The Characteristic Analysis of the Heat Storage System of the Solar-air Source Compound Heat Pump

A mathematical model of the all-glass vacuum tube solar collector-heat storage tank system of a new solar-air source compound heat pump has been developed, and the heat storage characteristics of the system have been simulated in Zhengzhou City at winter solstice. The changing regularity of the solar radiation intensity in one day, and the influence of the heat storage medium flow on the temperature variation of the heat storage tank and the heat-collecting efficiency of the solar collector have been analyzed. The simulation results reveals the dynamic heat-collecting features of the solar collector-heat storage tank system, and forms a solid basis for the combined operation of the solar collector-heat storage tank system and the heat pump system.
