What is a 4-Way Reversing Valve for air conditioning?
The function of the 4-Way Reversing Valve is “to realize the mutual conversion between refrigeration and heating by changing the flow direction of refrigerant in the system piping”;
When the 4-Way Reversing Valve is not charged, is the refrigeration mode, refrigerant out from the compressor, the first through the 4-Way Reversing Valve into the condenser cooling, and then throttling, into the indoor machine evaporator; When the 4-Way Reversing Valve is charged, is the heating mode, refrigerant from the compressor out, through the 4-Way Reversing Valve into the indoor heat exchanger, and then throttle into the outdoor heat exchanger.
