The thermal expansion valve is an important regulating component in the refrigeration system. Its main function is to adjust the refrigerant flow entering the evaporator to adapt to changes in the evaporator load, thereby maintaining efficient operation of the system. According to the structure and pressure sensing position, thermal expansion valves can be divided into two types: internally balanced type and externally balanced type.
1. Direct-acting solenoid valve: Principle: When the power is turned on, the solenoid coil generates electromagnetic force to lift the closing member from the valve seat
Solenoid Valve is an industrial equipment controlled by electromagnetism. It is a basic component of automation used to control fluids.
Sanheng is a professional manufacturer of Expansion Valve,Thermal Expansion Valve,Air Conditioning Expansion Valve. When the temperature of the air box head decreases, P1
A refrigeration unit is a device used to realize a refrigeration cycle, which reduces the temperature and maintains a constant ambient temperature by absorbing heat. It is one of the most critical core components in a refrigeration system, and is therefore also known as the main unit of a refrigeration plant.
Thermal expansion valve is also called temperature regulating valve. In the refrigeration system, the thermal expansion valve is installed on the liquid supply pipe of the evaporator inlet and has three functions:
