compressor

A driven fluid machine that raises low pressure gas to high pressure. Is the heart of the refrigeration system, which inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it after the motor runs, discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, Compression → Condensation → Expansion → Evaporation refrigeration cycle.


Condenser

The high-temperature and high-pressure refrigerant vapor discharged from the compressor is condensed by condensation into a liquid refrigerant, and the heat absorbed by the refrigerant from the evaporator is absorbed by the medium around the condenser.


Evaporator

Here the liquid refrigerant is converted to a gaseous state.


Dry the filter

In the refrigeration system, the function of the drying filter is to absorb the moisture in the refrigeration system, prevent the impurities in the system from passing, and prevent the ice in the refrigeration system from being clogged and clogged. Since the most clogged part of the system is a capillary, a dry filter is usually installed between the condenser and the capillary.


Expansion throttle

The high pressure liquid refrigerant from the receiver drier is throttled and decompressed to adjust and control the amount of liquid refrigerant entering the evaporator to adapt to changes in the refrigeration load while preventing the compressor from liquid hammering and the evaporator outlet vapor Abnormally overheated
