THEORETICAL AND EXPERIMENTAL RESEARCH ON THE THERMAL ENERGY MANAGEMENT SYSTEM OF DIRECT EXPANSION SOLAR HEATING

ABSTRACT
The author has established the experimental device of the direct expansion solar heat pump system. In this device, the bare plate solar collector is also used as a heat pump evaporator. Under the sunny weather in May, the author conducted an experimental study on the heat pump system. The experimental results show that during the whole experiment, the COP, and the heat collection efficiency of the system reached 2.50-3.35 and 50.0-75.2%, respectively. At the same time, the influence of solar irradiance, condensation temperature and other parameters on the COP and heat collection efficiency of the system is analyzed and discussed, so as to provide some reference for the application of the system.
