The thermal expansion valve regulates the refrigerant flow through the temperature of the temperature sensing bag. It can realize refrigerating or heating rapidly. Also, it can supply stable superheat, energy saving.
The thermal expansion valve regulates the refrigerant flow through the temperature of the temperature sensing bag. It can realize refrigerating or heating rapidly. Also, it can supply stable superheat, energy saving. The solenoid expansion valve controls the on-off of fluid through its own solenoid valve to accomplish the shutdown of independent circuit. It can solve the problem perfectly that the thermal expansion valve can not be closed completely.
