Product Description

Product Description

DESCRIPTION
AFV valve is a three-way solenoid valve, which is designed for defrosting by hot gas.
AVF valve is designed with internal communication in each inner chamber to avoid external pipes and connections.AFV valve is easy for installation.
Refrigeration cycle: when the coil is currently. joint B is closed.Valve is in the normal flow direction, from the evaporator to the suction of compressor (joint C to join  A)
Defrosting cycle: when the coil is energized, joint A is closed,hot gas flow from the pipeline (jiont B) to the evaporator (joint C) for defrosting

when the temperature or time in the evaporator reaches the set value,the solenoid valve is closed, the hot gas defrosting will end, and the refrigeration cycle will start again. (but the fan needs to be delayed for a period of time before starting, commonly known as dripping time)

AVF valve can only be connected with the exhaust integrated the main pipe. lt is not allowed to connect with the exhaust main pipe directly.
