The operation of the freezer will not cause any difficulties - we will tell you how it is arranged and works. This equipment allows you to store food longer; it is installed in shops, warehouses, private homes.
Design features and purpose of the freezer
They allow you to freeze and store a large number of products for a long time. Recently, they have become popular not only in retail outlets, but also at home. If you have a large family, and the freezer is not enough for cooking, you can install a chest.
It consists of:
- covers;
- baskets;
- control panels;
- temperature controller.
The circuit diagram is as follows:
Main nodes:
- Compressor. It pressurizes the system to distribute refrigerant through the evaporator tubes.
- Capacitor. It removes heat to the environment, prevents overheating.
- Fan. On some models, it distributes the cold over the chamber.
- Capillary tube. Refrigerant moves through it.
- Filter drier. Converts refrigerant from liquid to gaseous state.
- Dokupatel. Protects the compressor from liquid freon.
The principle of operation of the chest is not different from a conventional refrigerator. The compressor is switched on using a start relay and creates pressure for the movement of the refrigerant. The latter passes through the evaporator and filter, passing into a gaseous state and cooling the system. The presence of fans allows you to disperse the flow in the compartment, so defrosting such models is extremely rare.
As a thermal insulation, a sealant is used. It allows you to keep the set temperature longer.
The chest is located horizontally, the lid can open up or move to the side.
- Transparent cover. Often used in stores for easy viewing of content.
- The blind cover is suitable for household use.
The height of the body reaches an average of 75-85 cm, capacity - from 100 to 800 liters. For two or three people, 150-200 liters will be enough, while for a family of 4-5 people - 300-400 liters.
Some models are equipped with additional functionality and are able to maintain the temperature for up to 72 hours when there is a power outage.
The device may consist of one or two cameras. What is inside? Baskets and containers that can be removed and rearranged.
How to install and configure a chest freezer
If you are just going to buy equipment, listen to our recommendations. It is forbidden to place it in an unheated room, so when choosing, pay attention to the climate class.
Business Continuity
In the instructions, the label indicates the climate class - a combination of Latin letters. Each of them means the level of heat at which the device can be operated.
- SN - subnormal - from +10 to +32 degrees.
- N - normal - from + 16 ° C to + 32 ° C.
- ST - subtropics - + 16-38 degrees.
- T - tropics - + 16-43 degrees.
When installing, follow the manufacturer's instructions. Failure due to non-compliance with climatic conditions will lead to loss of warranty service.
Many are interested in: is it possible to put a chest on a balcony? It is possible if the balcony is insulated and the temperature corresponds to the recommended one.
If the room is too hot, the motor will run to wear, trying to cool the camera.
Most often we use the classes SN, N.
Installation Principles
Do you want the equipment to last as long as possible? Follow these rules:
- The appliance must not be built into furniture; it is designed for separate placement.
- The case should stand on a flat surface, not wobble.
- Between the walls of the chest and other objects should be a distance of 15 cm for normal ventilation.
- Installation is carried out far from heating objects, stoves. Avoid direct sunlight.
- Connection is made to a separate grounded outlet.
- If you want to connect to the generator, remember that its power should be 2-3 times higher than the consumption of the chest.
- After turning on, wait 2-3 hours before loading products into the camera.
Operational Features
What temperature is set in the compartment? It all depends on the strength and speed of freezing. The device is equipped with one thermostat, which is most often located in the lower right corner. This is a rotary switch or wheel that needs to be set to the desired position. The temperature sensor will maintain the setpoint.
Position 1 means the lowest mark. Position 4 is recommended for home use. Mode 6 means superfreeze - will be turned on until you turn it off manually.
Nearby are indicator lights:
- Green indicates stable operation.
- Red - the compressor is operating to reach the specified temperature. As soon as the task is completed, the lamp goes out.
The red indicator can be lit by the room temperature, the frequency and duration of opening the lid.
- Yellow - the temperature rose above -6 degrees.
What to consider:
- When the regulator is switched to the OFF position, freezing stops, but the device does not disconnect from the power supply.
- Overloading the compartment reduces the degree of cooling of the products.
- If you need to set a different temperature, switch the controller gradually, one division at a time. So the technique will have time to stabilize.
How to defrost a technique
When the ice on the walls reaches 5-10 mm, the chest needs defrosting. Before disassembling the contents of the camera, one day before defrosting, set the regulator to the maximum value. So the products last longer without cooling. Then:
- Unplug the appliance.
- Remove all products from the compartment.
- Open the lid wide open.
- Wait for the camera to thaw. This usually takes about a day.
Some models have a plug for draining melt water.
- Wash the walls and containers. Wipe the surface with a dry cloth.
- Connect the device to the network. Wait a few hours for the camera to gain temperature. Download the products.
Care and cleaning
You can wash the compartments both during installation and during operation.
- Turn off cooling on the regulator.
- Unplug the power cord.
- Wash the walls with a sponge dampened in a soda solution. Wash baskets and containers.
- Wipe the seal thoroughly. It must be kept clean to prevent mold.
- Exterior walls and lid can be washed with liquid detergent.
- Dry all surfaces.
Now you know how the chest is arranged and works, how to care for him so that he serves for a long time.
Last tip: when choosing, pay attention to the proximity of service centers, is it difficult to find spare parts and accessories for the model. Then no damage will be scary.
