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;
