Freezers: how to operate functions such as select operation

Freezer - a device for freezing and storage of frozen food supplies.

How to operate the freezer

The main nodes freezer are:

• evaporator;
• compressor;
• capacitor;
• capillary tube;
• Filter-dryer;
• thermostat.

The algorithm of the freezer compartment is identical to the principle of action the refrigerator. In the evaporator, the refrigerant boils and begins to evaporate, passing into gaseous form; thus it removes heat from the inner chamber.

The process takes place at low pressure.

The compressor draws refrigerant vapor under high pressure and injects them into the condenser. Next, the refrigerant is condensed into the liquid phase and giving heat to the environment. Passing through the filter-dryer and the capillary tube, it is fed to the evaporator.

The cooling cycle is repeated until such time as the temperature inside the chamber reaches the preset parameters, and then operates the thermostat and switches off the compressor.

Kinds

On the household appliances market offers a wide range of cooling equipment, which varies specifications, design and color schemes.
