The refrigerant flows through the compressor, which increases the pressure of the refrigerant. Next, the refrigerant flows through the condenser, condensing from a vapor form to a liquid form, releasing heat during the process. The heat released causes the condenser to "touch the heat." After the condenser, the refrigerant passes through the expansion valve, where it experiences a pressure drop. Finally, the refrigerant enters the evaporator. The refrigerant absorbs heat from the evaporator, causing the evaporator to evaporate. The evaporator draws heat from the area to be cooled. The evaporated refrigerant returns to the compressor to restart the cycle.
The compressor is a driven fluid machine that lifts low pressure gas to high pressure gas and is the heart of a refrigeration system. It inhales low temperature and low pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, discharges the high temperature and high pressure refrigerant gas to the exhaust pipe, and provides power for the refrigeration cycle. Compressors are considered the heart of the refrigeration system, the best performance of the compressor features a special term called "steam pump." The actual responsibility of the compressor is to enhance the pressure, the suction pressure to raise the pressure to the state
Thereby achieving a refrigeration cycle of compression → condensation (exothermic) → expansion → evaporation (endothermic). Compressor is divided into piston compressor, screw compressor, centrifugal compressor, linear compressor. Entry describes the compressor working principle, classification, parts, specifications, operating requirements, compressor production, common failures and environmental requirements, selection principles, installation conditions and trends.
Among reciprocating, rotary and centrifugal compressors, reciprocating is the most popular type in domestic or small commercial refrigerators. Reciprocating compressors are similar to car engines. The piston is driven by a motor to "breathe" and compress the refrigerant in the cylinder. As the piston moves down (increasing the cylinder volume) it will "suck" the refrigerant from the evaporator. When the refrigerant pressure in the cylinder reaches the pressure in the evaporator, the intake valve is closed. When the piston hit the maximum downward displacement, the compression of the refrigerant on the trip. The refrigerant is pushed into the condenser through the exhaust valve. Both the intake valve and the exhaust valve are designed such that the flow of refrigerant passes through the system in only one direction.
