Built-in appliances are a companion of most modern kitchens, where all technological paraphernalia is hidden behind aesthetic facades, without violating a single interior ensemble. In addition to built-in hobs, ovens and refrigerators, there are solutions for freezers. How to choose them and why it is impossible to build in a regular freestanding freezer – in this guide.
The decision to purchase an additional freezer cabinet is often determined by several reasons:
Lack of storage space. Especially in the case of using built-in refrigerators, whose useful internal volume is on average 20-30% less than that of freestanding ones. For a large family, there may not be enough space to store food, and you have to think about an additional unit.
Buying a refrigerator without a freezer. Such devices are only gaining their popularity. In this case, in the refrigerator, food intended for cooling, and in a separate freezer cabinet for long-term storage.
The need to store a large number of products for future use. Someone, due to household habits, likes to have a lot of food in stock, while someone has their own garden or farmstead, and you need to store stocks of vegetables, berries, fish, and meat somewhere. There is not enough space in a conventional freezer, and an additional freezer cabinet expands the possibilities.
Niche dimensions for embedding and usable volume
The best option is to first look at the equipment, and then design a kitchen set for it. However, in any case, even if the headset has already been purchased from you, the dimensions of the future equipment are the first parameter that you should pay attention to when buying a built-in.
The dimensions of the niche for embedding indicate the parameters of a floor cabinet or a pencil case that will suit you for the selected equipment. If these dimensions are not taken into account, then the selected equipment may simply not fit into the ordered set or standard modules, and you will either have to change the kitchen design or buy other equipment.
According to the standard, a height of 82-82.5 cm is a typical lower kitchen belt, compact under-counter freezers are implied. These are suitable for small storage, since their usable volume is on average up to 100 liters.
120-130 cm is an average height, already above the kitchen countertop, but still below a standard refrigerator. When built-in, such a freezer is already recessed into a tall pencil case, but due to the small height above it, a wall cabinet or additional shelves can be placed. The useful volume of devices of this size will be about 100-120 liters.
From 170 cm and above – standard full-size tall cabinet freezers with a total usable volume of 195 liters. Often located next to the refrigerator, forming a kind of single system. In such devices, there is enough space for products of daily use, and for storage for future use.
The total usable volume indicates how much the freezer actually holds.
The convenience of storage directly depends on the type of internal structure. It determines the number of drawers and hinged drawers inside the freezer, the total number of compartments. However, in the pursuit of shelves and drawers, it is much more important to figure out in advance which products and how you most often store.
A large number of internal sections is suitable if you store a wide variety of products from meat to berries and pastries – odors will not mix in separate boxes and sorting is more convenient.
However, if you, on the contrary, store products of the same type more often – especially bulky ones – it may be more convenient for you to choose devices with several, but deep drawers.
Freezing power – is determined by how many kilograms of products at room temperature the device is able to completely freeze per day. The parameter varies from 6 to 20 kg / day and directly depends on both the volume of the device and its working power. However, even with similar volumes of devices, the freezing power may vary.
This is an important indicator for those who download large batches at a time. For ordinary household storage of modest purchases from the store, small values \u200b\u200bare enough. If this parameter is greatly exceeded, this significantly increases the load on the freezer compressor, since it has to work at maximum power for too long. In addition, excessively long freezing worsens the condition of the products.
Maximum and minimum temperatures. In modern freezers, the average freezing temperature is -18 °C. It allows you to significantly increase the shelf life of products and at the same time not violate their condition. However, in many devices, the temperature can be adjusted in its own way, choosing from -11 ° C to -26 ° C.
Autonomous cold storage indicates how long the freezer will “last” without electricity and how long it will be able to keep food frozen. Suitable for places with frequent power outages. Most modern freezers stay at the 24 hour mark, but you can find both 19 and 12 hours.
Superfreezing is a useful option just for a one-time large bookmark of products. Most often implemented by turning off the temperature sensors and running the compressor at full capacity. Allows you to freeze the desired batch of products in a short time. Most often turned on and off manually. The main thing is not to forget to return the freezer to its usual mode of operation, preventing the compressor from processing for days.
Maintaining a constant working microclimate, as well as periodic defrosting of the device, can be done in two ways.
Manual defrosting is an old system in which a snow cap forms on the inner walls over time. Heat and condensate emitted by fresh products are not removed to the outside and do not evaporate, gradually settling in the freezer chamber in frost. Devices with manual defrost have the only significant plus – they are much cheaper than No Frost systems.
There is also one minus, but a big one – such freezers must be periodically defrosted manually, unplugging the appliance from the mains and waiting for complete thawing. An accompanying difficulty with manual defrosting is the need to pull out all the food from the chamber, which can be very inconvenient with a constant full load, especially if you have a 200-liter cabinet.
No Frost is a modern and convenient solution that automatically removes condensate and constantly maintains dry air inside the chamber. At No Frost, fans ensure constant air circulation through the inner chamber and expel fumes. Condensate freezes on the back wall, the device periodically turns on the heating of the cooling element, the ice melts and flows down into a special tray. It is also not necessary to manually pour out the condensate – it evaporates due to the heat of the compressor.
Human participation in the operation of the No Frost system is not required, and this is the main plus. The chamber will always be dry, clean, without ice and snow. However, this solution also has some disadvantages. The first is that the microclimate in the freezer becomes too dry, and loosely closed products will be prone to airing and drying out, so they need to be packed for storage especially carefully. The second disadvantage is the relative high cost in comparison with manual defrost devices. However, this disadvantage is objectively leveled by the resulting comfort.
In a sense, the compressor is the heart of the refrigerator. This is the main motor that pumps cold and thanks to which the set temperature inside the chamber is maintained. Two types of compressors are currently in use – linear and inverter.
The principle of operation of a linear compressor is based on constant switching on and off: sensors determine the set and actual temperature conditions and, if necessary, start the compressor. In this case, the compressor starts immediately at full capacity and at the slightest deviation from the set temperature.
An inverter compressor works differently. Its main feature is an adjustable shaft speed, which allows you to smoothly increase and decrease engine speed. Thus, a stable temperature is maintained in the chamber without sudden jumps in the operation of the compressor.
The advantages of an inverter motor are that such a freezer has much higher energy efficiency – an inverter compressor consumes on average 20% less electricity due to operation at constantly low speeds.
Also, the inverter compressor is more durable, runs quieter and is more stable in performance – with them there is less risk of temperature fluctuations inside the chamber. Read more about the operation of inverter compressors in refrigeration equipment here .
Child lock. Security option to prevent doors from opening.
Display . Convenient display of the selected operating modes on the external screen of the freezer.
Alerts and indication. Indication of temperature and selected settings allows you to always monitor the state inside the freezer, adjust it and notice malfunctions or unwanted temperature fluctuations in time.
Noise level. In general, freezers are fairly quiet appliances. Their noise level ranges from 38 to 44 dB, which is unlikely to interfere with your comfort, especially behind the walls of cabinets. Values closer to 45 dB are perceived as a quiet conversation in an undertone – audible, but not disturbing. Below 40 dB – almost inaudible. If you are very sensitive to any noise, or the freezer is located very close to the recreation area, choose appliances with the lowest noise level.
Energy consumption and climate class
Due to the fact that the freezer is a fairly large and powerful device that operates 24/7, its energy consumption is not the least important. Most manufacturers are now trying to maintain an energy class of level A and above. This classifies the technique as economical. At the same time, classes A + and A ++ save up to 35% of electricity. Such devices are more expensive, but quickly pay off.
The climate class shows at what ambient temperatures the equipment can function comfortably. This parameter is not particularly important if you are buying appliances for the home, but it matters for non-residential premises or placement on a balcony.
Class N — from +16 °С to +32 °С
Class SN – from +10 °С to +32 °С
ST class — from +18 °С to +38 °С
Class T – from +18 °С to +43 °С
It is impossible to go beyond the limits of permissible values, otherwise it will sharply negatively affect the performance and durability of the device.
