The company has developed a double source heat pump water heater system with air supplement and enthalpy increase, which solves the problem that the ordinary series double source heat pump can not reasonably distribute the refrigerant flow, and realizes the automatic distribution of the refrigerant flow at the low-pressure end under heating conditions. At the same time, an economizer is added in the system to realize the supercooling of the hot end, and extract the gas phase in the refrigerant flow in the primary evaporator in the low-pressure section, so as to enhance the heat exchange effect in the secondary evaporator. At the same time, it gives full play to the advantages of the air supplement enthalpy increase system, enhances the low-temperature adaptability of the system, expands its application range, and is energy-saving and efficient. A regenerator is added to the system, and heat exchange is added in another step, with a higher coefficient of performance.
