Refrigeration principle of refrigerator

The refrigeration principle of refrigerator is as follows:

Liquid refrigerant is throttled by the capillary tube, reduce the pressure, the refrigerant from the liquid state to the vapor state in the process of the refrigerator absorbed the heat of the space, the surface of the evaporator gradually frost, the temperature inside the box is gradually declining; has been evaporated after absorbing the heat of the refrigerant vapor has been running compressor suction, compression and then become a high-pressure, high-temperature vapors; and then into the condenser will heat dissipated into the air to be liquefied; through the drying filter filtration may carry dirt or moisture and so on continuous cycle refrigeration. Condenser will be the heat dissipated into the air is liquefied; through the drying filter filter may carry dirt or water, throttled down by the capillary ...... continuous cycle of refrigeration in turn. Therefore, the working principle of vapor compression refrigeration cycle is briefly described as: evaporation? -- compression -- condensation -- throttling four processes.
