Abstract
An air source heating air conditioning hot water machine adopts the combination of only two refrigerant electromagnetic valves and one refrigerant check valve to solve the hidden danger in the prior art of an air source three-way set that as a changed-over heat exchanger stores refrigerant liquid constantly through six to eight refrigerant electromagnetic valves, fluorine shortage in a heat pump cycle is aggravated gradually, fundamentally avoids the refrigerant circulation between the changed-over heat exchanger and the heat pump cycle, and realizes the long-term self-stabilization operation, therefore, the air source heating air conditioning hot water machine is endowed with the four functions of heating, air conditioning, hot water supply as well as air conditioning together with hot water supply through simpler structure, lower cost, more reliable operation and improved efficiency.
