Detailed Description:
Expansion valve, also called throttle valve, is the main component of the air conditioning refrigeration system. It is installed at the entrance of the evaporator and is the dividing point between the high pressure and low pressure of the air conditioning refrigeration system. Its function is: throttling and decompressing the high-pressure liquid refrigerant from the receiver dryer, adjusting and controlling the amount of liquid refrigerant entering the evaporator to adapt it to changes in refrigeration load, while preventing the compressor from liquid hammer ( That is, the unevaporated liquid refrigerant is compressed after entering the compressor, which can easily cause damage to the compressor valve plate) and abnormal overheating of the vapor at the outlet of the evaporator.
The role of thermal expansion valve:
The thermal expansion valve is installed at the entrance of the
evaporator and is often called an expansion valve. It has two main
functions:
1) Throttling: After being throttled by the orifice of the
expansion valve, the high-temperature and high-pressure liquid
refrigerant becomes a low-temperature and low-pressure misty
hydraulic refrigerant, creating conditions for the evaporation of
the refrigerant;
2) Control the flow of refrigerant: the liquid refrigerant entering
the evaporator, after passing through the evaporator, the
refrigerant evaporates from liquid to gas, absorbs heat and reduces
the temperature in the car. The expansion valve controls the flow
of refrigerant to ensure that the outlet of the evaporator is
completely gaseous refrigerant. If the flow is too large, the
outlet contains liquid refrigerant, which may enter the compressor
and cause liquid hammer; if the refrigerant flow is too small, the
evaporation is completed in advance, causing Insufficient cooling
