When the air conditioner is in the refrigeration state, the four-way valve is not energized (initial state),the four-way valve is in the state of AB connection, DC connection, the refrigerant is compressed by the compressor into high temperature and high pressure gas, through the A port of the four-way valve, discharged from the B port, into the outdoor heat exchanger (condenser), after the condenser absorbs cold and heat release, it becomes a medium temperature and high pressure liquid, after passing the expansion valve, it becomes a low temperature and low pressure liquid, after the indoor heat exchanger (evaporator) endothermic and cooling action, it becomes a low temperature and low pressure gas, through the four way valve D port, Return to the compressor from port C and continue the cycle.

When the air conditioner is in a heating state, the four-way valve is energized, the motor drives the valve core to move, so that the AC is connected, DC is connected, the refrigerant is compressed by the compressor into high temperature and high pressure gas, through the A port of the four-way valve, discharged from the C port, into the indoor heat exchanger (condenser), after the condenser absorbs cold and releases heat, it becomes a medium temperature and high pressure liquid, after the expansion valve becomes a low temperature and low pressure liquid, after the outdoor heat exchanger (evaporator) heat absorption and cooling action, it becomes a low temperature and low pressure gas, passes through the four way valve port D, and returns to the compressor from port B , and continue the loop.
