Or there are other models that you can privately chat with me about
separately.
Throttling and pressure reduction: The expansion valve throttles
and reduces the pressure of the high-temperature and high-pressure
liquid refrigerant condensed by the condenser, making it a
low-temperature and low-pressure gas-liquid mixture that is easy to
evaporate, creating conditions for the evaporation of the
refrigerant.
Adjust flow rate: The expansion valve can automatically adjust the
refrigerant flow into the evaporator based on the temperature
signal obtained from the evaporator temperature sensor, in order to
adapt to the constantly changing cooling load requirements.
Protecting the compressor: Another important function of the
expansion valve is to protect the compressor from liquid hammer and
abnormal overheating of the evaporator outlet vapor.
Product Legend
We all ship genuine products, and the accessories are specifically
designed to match the interface of the air cooler
Thermostatic expansion valve regulates the flow of liquid
refrigerant entering the evaporator. The flow is controlled by a
thermal ball valve attached to the evaporator outlet suction pipe.
Thermostatic ball sensing evaporator heating and regulating valve
Enhanced adaptability to changes in refrigerant dosage; Enhanced
comfort and short defrosting time;
