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
