25 criteria for choosing the best refrigerator

For many decades, the refrigerator remains an indispensable unit in every kitchen. On the market there are many different modern models, differing in a set of functions, design. Before you choose a refrigerator that fits perfectly into the interior and will meet all the requirements during operation, you must be familiar with the important parameters of refrigeration appliances.

Dimensions of the refrigerator

Each model has its own dimensions. This is an important parameter that affects the basic selection criteria. A large family will need a roomy refrigerator, which will have enough space to store food stocks. Farmers and gardeners should also take a closer look at large refrigerators and freezers, since they will be very useful for storing crops and in the slaughter season.

Small kitchen is better not to overload the overall equipment. Fit a small budget refrigerator, up to one and a half meters in height. Especially if the family consists of one, two people. The dimensions of the embedded models should be discussed in advance with the master who mounts the corresponding module.

Overall dimensions include height, depth, width. With height, there are hardly any problems in ordinary apartments and houses, and the width and depth of most models rarely deviate from the standard. Dimensions of large-sized designer equipment should be taken into account at the initial stage of kitchen design, when furniture is located.

Useful volume

In the characteristics of the refrigerator, you can see two parameters: total and net volume. At the second indicator, it is necessary to pay special attention, because it reflects the actual capacity. Net volume is specified without taking into account shelves, containers for eggs, trays on the inside of the door.

The smallest capacity in single-chamber refrigerators. Their useful volume ranges from 100-150 liters. Two-chamber units make up to 350 liters. The largest volume of multi-camera models Side-by-Side with hinged doors - up to 700 liters.

Number and location of cameras

When choosing refrigeration equipment, you must take into account the number of family members, personal preferences of each. If it is not customary to freeze food, then a large freezer will be useless. For thrifty housewives, it plays a huge role, so you should pay attention to its location. There are several camera layout schemes - European, Asian, American. All types of refrigerators can be divided into the following groups:

cooling chamber

The main compartment of the home refrigerator is designed for the storage and cooling of food and beverages. In most models takes 2/3 of the total. Refrigerators are short-term and long-term storage. In the first case, the products can be stored no more than 5 days, the second option significantly extends the shelf life, but only already prepared, specially frozen pieces of meat, fish, puff pastry and others.

In the compartments for gentle cooling, you can keep only fresh vegetables, drinks, desserts. They are located as far as possible from the freezer. The shock freezing departments turn any product into ice in 1.5 hours. Suitable for freshly prepared dishes that require instant freezing.

Freezer

In any home, even with the most picky owners, there should be a fridge freezer. She will definitely come in handy. Low-temperature compartments are of several types. Features of each model are marked with special symbols:

• 1 star (*). Short storage, no more than a week at a temperature of -6 degrees;
• 2 stars (**). The deadline for finding products is 1 month. Temperature -12 degrees;
• 3 stars (***). Taste quality food products remain unchanged for 3 months. Temperature -18 degrees;
• 4 stars (****). The maximum shelf life is 12 months at a temperature of -24 degrees.

Refrigerator Cooling System Types

Cooling of the internal space of refrigeration equipment can occur in several ways. Each manufacturer uses the most convenient and popular option for a separate model in the line of technical innovations. When choosing a device for the home, you need to focus primarily on these indicators. All available cooling systems differ in the device and the principle of work.

Compressor system

Household units for home often equipped with just such a cooling system. It is the most common and practical. Used in household units "Stinol", "Atlant". Despite the impressive volume - economical and safe. The cooling process starts the compressor (linear, inverter motor), which causes the freon to move through the tubes. Heat generated when the engine is running out through a condenser, plastic tubes on the back or side of the refrigerator. Simple device helps to avoid overheating.

Manufacturers do not recommend installing compressor refrigerators near appliances that emit heat (batteries, heaters, stove). Additional heating of the device will quickly disable the motor.

Most models operate on a single compressor that cools the freezer and refrigeration chambers. Less common are refrigerators with two compressors, each of which is responsible for lowering the temperature in a separate chamber. This allows you to adjust the temperature of the compartment, turn it off without loss for another. The system is not very popular, because its positive aspects of work overlap the negative aspects - the high cost of the unit, the No Frost thawing system is not provided.

Absorption system

The main difference between models with this type of cooling from conventional designs is that they lack a compressor. Such refrigerators work silently, have a long service life. The negative aspects include the impossibility of repair when the absorption system fails.

Cooling chambers, as in the compressor system, is due to the movement of the refrigerant. But in this case, the flow moves due to the dissolution of ammonia in water. A heat exchanger heating system using a generator is applied to small refrigeration devices. To maintain the processes of large models requires a lot of electricity.

The positive side of this type of cooling is the ability to use liquid fuel, gas as an energy resource. In domestic conditions, models are used to obtain ice, short storage of products. Russian companies produce absorption units ranging from 30 to 200 liters.

Thermoelectric system

The device is based on the Peltier Effect. Produce only small-sized models. The main purpose of such refrigerators is high-quality cooling of products during any movement. Eco-friendly mini-unit does not release refrigerants into the atmosphere, it remains effective at low current consumption. Able to work continuously from the vehicle's cigarette lighter when the engine is turned on. At the time of parking, its battery is discharged after 4 hours. In the home 220 V thermoelectric device can not be connected. It is designed to operate from a network of 12 V. It should be turned on at home only through an adapter and a stabilizer.

Thermoelectric portable refrigerators come in various shapes and designs. The smallest low-cost models hold only a few bottles or cans. There is more space in the rectangular chests, you can hold a supply of provisions for the entire trip. Some car refrigerators have a high number of floors, special tanks for distinguishing the degree of cooling.

Defrost systems

Any refrigerator with a certain frequency should be defrosted and cleaned. This is a necessary process by which the work of the system is stabilized, ice freezing, harmful microorganisms and unpleasant odor are removed. Such actions significantly extend the life of the equipment.

Modern models of refrigerators are able to automatically eliminate frozen condensate, thanks to special additions. To prevent the formation of ice they are equipped with the following defrosting systems:

• Drip. The most affordable for buyers. This fridge is very convenient to use. The evaporator and the special panel independently regulate temperature indicators. Accumulated condensate flows into the tank along the internal wall of the refrigerator.
• Automatic. The built-in defrost system is activated when frost forms. It works on the principle of the water cycle - fluid accumulation, evaporation, return to the original place.
• Semi-automatic. It is installed in multi-chamber refrigerators. If the defrost drip system is working in the main compartment, then to get rid of the ice cap in the freezer, you will need to disconnect it from the network.
• No frost. It works due to air circulation in all compartments of the refrigerator. Airflow is generated by built-in fans. The evaporator is outside the fro fro chamber. The system of dry thawing completely prevents the formation of ice, the packages do not freeze inside the compartments, a uniform temperature is always maintained. Details can be seen in the review.

No automatic defrost system replaces complete defrosting. The procedure should be carried out at least once a year. The accumulation of even minimal icings negatively affects the operation of all processes of the refrigerator.

Additional characteristics of refrigerators

It is possible to choose exactly the necessary product for your kitchen from a variety of models according to three main features - functionality, harmonious combination with the interior, usability. Many modern refrigerators are equipped with additional features that improve their performance. It can be a variety of sound signals, antibacterial coating, automatic power control, and so on.

Some additional functions may not be combined in a specific model. Giving preference to one modern technology will have to sacrifice another. For example, compression devices are characterized by great cooling capacity, but make noise when the engine is running. Silent thermoelectric refrigerators have a high cost, they consume a lot of electricity in autumn, but attract buyers with their simplicity of construction, low weight.

Economy Class

One of the important indicators when choosing a model of refrigeration unit for the home. It determines the likely cost of electricity to operate and maintain the necessary functions. Refrigerator included in the network around the clock. In some brands, electricity is consumed only when the compressor is turned on, when other devices wind kilowatts continuously. Manufacturers mark their goods with special symbols according to the energy efficiency index. There are the following classes of efficiency:

1. Class A. The most highly efficient models with high ratings are A +, A ++. Energy consumption level up to 55%;
2. Class B. Average profitability index up to 75%;
3. Class C. The level of energy consumption is high, up to 95%;
4. Class D. Old-fashioned models with a huge profitability index, up to 110%.

Noise level

The volume of the refrigerator during operation should not exceed 53 dB. The noise levels are divided into low - up to 34 dB, medium - up to 44 dB, high - more than 45 dB. Such information is reflected in the passport of the device. For a human ear, these are minor interferences, the hearing aid quickly adapts to them. But in any case, a quiet domestic refrigerator is more comfortable to operate.

The most pronounced sound effects creates a compressor. If it comes into contact with adjacent parts, the work of the motor is complemented by vibration. It is characteristic that the refrigerant rumbles, moving through the tubes. You can hear well how the fan blows the cameras and clicks the relay when changing the mode.

Absolutely silently refrigeration can not work, but you can independently try to reduce its volume. It is necessary to install the refrigerator on the most even surface by adjusting the legs or placing a lining under them. It should not come into contact with other household appliances, fit snugly to furniture, with the exception of built-in models. You can also improve the outer part of the camera, overlaid with special materials that absorb noise.

Climate class

A lot of additional features attracts the attention of customers at the moment of choosing a refrigerator. Climate control, unfortunately, not one of them. This important characteristic indicates the possibility of operating equipment at a certain temperature, humidity.

Warranty service may be provided if the refrigerator has been operated in conditions acceptable for its climate class. This indicator is divided into several types:

• Normal (N). The most common class. The operating temperature range is 15-33 ° C. In winter, the refrigerator should work in rooms with heating, and in summer in aired kitchens;
• Subnormal (SN). It works without problems at temperatures from 10 ° C to 32 ° C. Can be installed in cool basements, unheated hallways;
• Subtropical (ST). Models are designed for hot regions with high humidity. Such refrigerators tolerate heat up to 40 ° C.

There is also a T marking. It is applied to appliances capable of withstanding a temperature of 45 ° C in a dry tropical climate. Such refrigerators are practically not supplied to the Russian market. They are replaced by multi-class models that operate smoothly over the entire temperature range presented above.

Air distribution system

A useful additional feature allows you to distribute the cooled air evenly across all chambers. Special fans deliver cool streams to the most inaccessible corners, to closed vegetable boxes and other departments. Models with a forced circulation system can be equipped with beautiful glass shelves and partitions, instead of standard metal gratings. On the walls of the refrigerator does not increase the snow layer, there is no need for frequent defrosting.

In the refrigeration compartments, single-level and multi-level air flows can be arranged. Each manufacturer will improve its system, as much as possible adapting to the needs of the consumer. Fans can be located on the side, rear wall of the unit and create a vortex, direct flow.

Humidity control

The indicator of moisture content in the refrigerator is always less than outside. In order for the products in the freezer or any other chamber not to dry out and not be moldy, it must be regulated. This function is complemented by refrigerators with fresh areas. In the camera, you can set the humidity level suitable for each specific product. For example, chilled fish and meat will be enough for 50%, and vegetables will be better preserved at 95% humidity.

Moisture content may increase due to insufficient fit of the door, frequent use of the compartment for the preparation of food ice. Constant sputum and smudges adversely affect the quality of products, reduce the efficiency of the unit. The cooling evaporator does not work well. On it frost is more often formed, hindering his work. Increased loads significantly reduce the durability of the refrigeration unit.

With the help of an electronic humidity controller, you can use any isolated chamber to store a specific group of goods. If the sensor is installed in a common compartment, products should be placed on different shelves taking into account temperature changes in height, respectively, and humidity. If the warm mode is adjusted in the chamber, the temperature in the upper zone will be +10, in the average +7. In the bottom + 5 degrees.

Super freeze

Place for forced superfrost compartment was found in the freezer. Such a function is mainly found in multi-chamber refrigerators. The developers have supplied many models with a special system that allows for a short time to turn a large volume of products in the compartment into a weekly freeze.

A feature of this function is the constant operation of the compressor when it is triggered. It will not turn off until all the goods loaded into the compartment have taken the expected state. The temperature in the shock freezing chamber drops to -35 degrees. When in the usual freezer just -18.

Produce models with automatic and manual superfrost mode. Благодаря автоматизации процессов, спустя некоторое время (от пары часов до нескольких суток), происходит отключение режима. Температура в камере опускается до обычных -18 градусов. Если такой функции нет, выключить интенсивное замораживание можно вручную, повернув реле.

Vacation mode / vacation

Leaving the refrigerator in working condition for a long time without food, you can not only get a musty smell, but also spoil the equipment. Vacation mode will help to avoid such troubles. Many models, ranging from the average price category, are equipped with such a function. In order to minimize power consumption, experts give recommendations on setting temperatures not lower than +15 degrees.

In single-compressor refrigerators, with one cooling circuit, it is impossible to completely turn off the freezer, while leaving the rest of the compartments running. Some units with two compressors support two optimal variants of the "holiday" mode for low-temperature compartments at once - preservation of the normal operation mode and complete shutdown.

Automatic ice generator

The system of cooking edible ice is found in models of high price category. To do this, the unit must have a separate compartment connected to the water supply, the possibility of filtering. In some models, it is possible to manually pour already purified water into a container.

The ice generator does not freeze the water, but distributes it into forms, maintains the temperature, and distributes it through a special dispenser. It is not necessary to open the refrigerator door, the device discharges water in a liquid, in portions frozen, when you press the desired button. The automatic cooling compartment in some units is complemented by a mill for making ice chips. Such refrigerators stand out due to the following factors:

• The size. Models have a separate vertical compartment in the entire height of the unit, which increases their dimensions;
• The presence of a decorative panel with a variety of fasteners;
• Additional awnings on the doors;
• High energy efficiency. There is no need to open the freezer often to collect ice.

Antibacterial wall coating

The main reason for the appearance of spoiled food in the refrigerator is the presence of microorganisms. Bacteria and fungi do not die at low temperatures. And just slow down the processes of life. To solve this problem, manufacturers began to coat the walls of some models with antibacterial coating. A special layer based on silver particles can not only stop the spread of the fungus, but also destroy it completely.

In refrigerators with a good biological climate products are stored longer, there is no stagnant smell. It can be a simple antiseptic coating of just 100 microns, the treatment of special film with silver ions inside the chambers, a dense ceramic layer with antibacterial particles. Any technology is reliable, copes well with the work - eliminates the development of microorganisms and dangerous infections.

Presence of air filter

An integral addition to all modern refrigerators - a filter that absorbs odors. The air cleaner is able to neutralize the unpleasant aromas that emanate from smoked meat, raw fish, citrus fruits and other products. The essence of the work of special devices is to clean the air at the time of its passage through the filter element.

The system of cleaning the air entering the refrigerator is very popular. It is used by well-known manufacturers: BOSCH, LG, Electrolux. In some premium models, such a device is complemented by a second filter that destroys fungi, bacteria. The service life of an odor-absorbing element is 6 months. Working longer, the filters themselves become distributors of bacteria and odor.

Cold accumulators

A simple cold storage device is used for cooling, maintaining the required temperature in a portable thermal bag or a sealed mini-fridge. Plastic container with a special substance inside ensures the safety of products during country picnics and long trips. Such an accumulator does not accumulate cold, but simply conveys its temperature to beverages, various quickly perishable products.

The service life of the cooling elements is unlimited, and the principle of operation is very simple. Before use, it must be placed in the freezer and freeze well. Then it is transferred to the cooler bag with already cooled products and sealed. The inner walls of the portable simplest refrigerators are covered with foiled material, which helps to maintain the desired temperature for up to 24 hours. You can store the cold battery in the freezer in a frozen state or chilled in a drawer or on a shelf.

The most important part of the coolers is the internal filler. It is its properties and characteristics that affect the safety of products. Factory cold batteries are of the following types:

• With a filler in the form of a gel. The main substance is carboxymethylcellulose, packed in a sealed bag, absolutely safe. It has the ability to keep both low and high temperatures for a long time;
• Saline. Rectangular durable plastic cans with blue saline liquid. During the day, keep the temperature from -20 to +5 degrees;
• Silicone. Foil-shaped film bags are suitable for long-term cooling. They can keep the temperature from 0 to + 2 throughout the week.

Ergonomics of the refrigerator

One of the main kitchen assistants should be not only the most functional, but also convenient to use. Properly equipped cameras will facilitate interaction with them, speed up the search for the desired product. You will not forget about a small piece of sausage, rolled into the far corner or sliced ​​lemon, if such residue will be allocated a special place on the side door.

Convenient in height shelves will allow you to store bottles with drinks, packs with juice in an upright position. For round fruit in many refrigerators inclined containers are provided, and for oblong special rag hammocks are suspended. These accessories in the units - a great way to save space. Drawers allow you to observe the commodity neighborhood and prevent the mixing of odors.

Shelves

Refrigerators of the same type from competing manufacturers can be equipped with shelves of different material. They may differ not only in the method of manufacture, but also in shape, color, texture and other factors. The size of the internal horizontal partitions depends on the size of the refrigerator. Internal shelves can be of the following types:

• Metallic. Found in models of economy class. They are freely adjustable in height, removed, retracted. The shelves for main storage in the budget refrigerator are simply enameled. Stands for products in modern units have plastic coatings. Both options are durable, not afraid of mechanical stress. The disadvantages include the rack form and the possibility of rust formation at the site of the enamel chip;
• Glass. Made of high strength tempered glass. Products capable of withstanding a load of up to 30 kilograms. This is the most expensive, outwardly attractive option. Shelves have plastic sides and edging. They can be wide or reach half the depth of the refrigerator. The main drawback is an obstacle to the normal circulation of air inside the chambers;
• Plastic. Make them from special food plastic. This is the least reliable option for refrigerator shelves. Plastic coasters are very fragile, over time they crack, exfoliate and turn yellow.

Shelves on the doors

Boxes on the side door of the refrigerator are more often used for storing products for everyday use: eggs, sauces, notched vegetables and fruits. In some models, the lower shelf of the door is equipped with a special device for storing round bottles. Products made of plastic, can be open or closed, transparent and matte.

On the door is usually provided space for 3-5 horizontal removable shelves on its entire width. There are units with scattered shelves, balconies of small size. The surface of the inner side of the door in some models is equipped with additional holders to change the location of products. Next to such devices may be a mini-bar - embedded window with a separate door or a reservoir for chilled liquids - a recess with a dispenser.

Containers

For high-quality and convenient storage of products in many models there are special boxes. Vegetable containers are in everyone, even in the simplest refrigerator. They are placed in the opposite freezer part, have a cast form. Production material - plastic. They can be transparent and opaque, with or without a separate lid. For open containers, a special glass lining is provided to keep the contents moist at any temperature in the refrigerator. A pair of identical drawers can be easily pulled out without touching the upper shelves.

In some models, retractable containers replace conventional shelves. Boxes are provided for storing large containers. They are equipped with special holders so that the goods in a round container do not roll. Tender berries are stored in closed boxes with a special rough bottom, so that they do not roll down and stick together.

Freezer drawers

Most budget fridges do not have drawers in the freezer. The spacious compartment is simply divided into zones by several shelves. But if the manufacturer has provided the presence of containers, the improved function should be used to the maximum. Thanks to such a container with a tight panel products are stored longer. Freezers can be equipped with several types of drawers:

• Retractable cameras;
• Hinged trays;
• Folding boxes.

In refrigerators with a large freezer located near the floor, use wide drawers. Collapsible design is very easy to maintain. If a part of a plastic product has broken, you can easily find a replacement in the manufacturer’s service center. Solid containers are made of high strength material that is well adapted to extremely low temperatures.

Lighting

Thanks to the design and the door seals, the walls of the refrigerator do not allow light, heat rays to pass through. This technique has its own lighting provided by the manufacturer. More often, lamps and lighting modules are located on the side wall. This type of accommodation is very convenient. The light appears automatically when you open the door. The light bulb on the back wall covers the entire chamber, not overlapped by products. Lamps can be mounted on the top panel or visor. These are the most unfortunate options. The light does not reach the lower shelves.

Different brands of refrigerators can be equipped with different types of lighting. The quality of light depends on the chosen system and the light bulb itself. You can find the following illumination:

• Incandescent lamp. Affordable, easy to use option. It emits a bright yellow light. Disadvantages - very hot;
• Halogen lamps. Consumes little power. The light is bright, soft. Disadvantages - heat during operation;
• Fluorescent lighting. Lamps emit a white glow, have a high resource of work (15 thousand hours), do not heat up. Disadvantages - the content of hazardous mercury vapor. On the advice of manufacturers, they should be disposed of in special places;
• LEDs. The safest, most economical way to deliver light. Consume a minimum of electricity, can serve up to 10 years. Disadvantages - difficult repair and replacement.

Pens

Refrigerator - frequently used household appliances. Every family member takes his pens daily and repeatedly. Of great importance is their location on the outside of the door. They should be at a convenient height for all. The upper doors of large multi-compartment refrigerators should have grooves in the panel at the top and bottom.

The handle of the refrigerator has a high functional, decorative value. Models with simple grooves quickly lose their attractiveness, as dirt accumulates in the grooves. Due to the design features of such parts there are difficulties with their washing. The most convenient option - a vertical, horizontal handle, similar to the door. It may be small enough to pass a hand, or long full width, the length of the refrigerator compartment. There are models with a diagonal arrangement of handles.

a door

Refrigerators are single-door and multi-door. The first option is considered standard and is implemented in most models. Units with a deaf door are easy to operate, spend less energy when working than similar-volume counterparts with multiple doors. The possibility of cold leakage through the doorway is reduced.

Multi-door refrigerators with a hinged door mechanism (Side by Side) are in great demand. Large units can be detached and built-in. Will only look good in a large, spacious kitchen. An interesting option is a transparent door. Showcase doors look very nice. But such models are rarely purchased for everyday use, because they require regular maintenance. The condition of the glass surface must be carefully monitored. Practical and convenient unit - "door to door" from LG.

Design and equipment of modern refrigerators

The refrigerator is part of the kitchen interior. It should be not only functional and equipped with useful additions for owners, but also have a pleasant color, correct, convenient form. Manufacturers offer buyers a wide variety in appearance and style of the model. The most common white fridges are of standard, streamlined shape.

In a sufficient range on sale you can see units with sharp corners, narrow and elongated, or vice versa, low and wide. They can be a variety of shades. Popular colors: gray, metallic, gold. Many refrigerator manufacturers decorate their doors with graphics, geometric patterns, colors and even Swarovski crystals.

Each manufacturer annually expands the range of its equipment, equipping refrigerators with new, useful functions. In modern units, the following additions are common:

• Electronic control. Models have a special digital display, which displays information about the temperature inside the refrigerator. A beep will alert you of any changes (open door, rising, falling temperature);
• Smart Fridge Built-in wi-fi significantly expands the functionality of the model. You can control the refrigerator through any smartphone, computer or tablet. You only need to install a special program of the manufacturer. A “smart” fridge will report on the fullness of products, their shelf life, and even make their own orders in online stores;
• Function "self-test". In the event of a malfunction, a special display will show information with an error code. Combinations of letters and numbers vary by model;
• Automated ice maker. Mounted in a special compartment on the outside of the door. Purified water enters batch trays, freezes and is transferred to the dispensing tray;
• Camera for wine. Managed separately from other areas, has its own door and wooden shelf-stand. With the help of a relay, you can create the ideal temperature for an elegant drink.

Built-in refrigerators

The main feature of this unit is a complete fusion with kitchen furniture, saving space. This type of refrigerator is suitable for both spacious and miniature kitchens. Before choosing a model, it is necessary to take measurements of the opening under the refrigerator, taking into account the depth. Going beyond the common feature of the kitchen unit unit can spoil the whole picture.

A built-in fridge in a small kitchen will save precious space. It works practically without noise, since the sound is absorbed by the kitchen cabinet around the device. A model hidden in a niche can be of any color. An inconspicuous unit will not violate the design direction. Universal equipment suitable for offices, bars, hotels. Among the shortcomings can be noted the complexity of installation, high cost, small range of styles and models.

How to build a fridge yourself

To build a refrigerator in the kitchen, no special skills are required. You will need a minimum set of tools, attentiveness and physical strength. Work will take place in several stages. First of all, it is necessary to determine the place and method of connecting to the network. Then you should free up space for work. Furniture, household appliances should not interfere. If necessary, the kitchen wall modules are dismantled. Low models can be covered with a table top. For large refrigerators use a decorative plinth.

Not every family can afford the purchase of an expensive built-in refrigerator. The design of the room will not deteriorate, if for this purpose you use the most common stand-alone refrigerator. Save space in the kitchen in this way will not work. Therefore, it is necessary to think several times about the feasibility of such a step before starting work. Если необходимость встраивать агрегат подтверждена, первое, что следует сделать - сконструировать короб, гармонирующий по цвету и дизайну с мебелью на кухне. Готовое изделие устанавливаем на выбранное место, помещаем внутрь холодильник и делаем дверь.

Conclusion

Каждый человек имеет свои требования к современной технике в соотношении цена - качество. Before buying a refrigerator, you need to evaluate its work and think about the need for additional functions. From the list of the most popular models from well-known brands, you can choose as expensive design equipment of the desired size, as well as a simple white assistant standard size.
