Proposed a new type of integrated heat / energy storage / evaporation solar water heater system, and analysis of the working principle of the system to build the system of experimental test equipment. Based on the experimental tests, the heat gain efficiency of the integrated solar heat pump water heater system is defined and compared with the direct-expansion solar heat pump system. The performance coefficient under different operating conditions is analyzed. Experimental results show that the heat gain efficiency of the heat / energy storage / evaporator with integrated heat / energy storage / evaporation solar heat pump water heater system is higher than that of the direct-fired solar heat pump water heater. The integrated heat / energy storage / The average coefficient of performance COP of the heat pump water heater system is 7.56.
