Theoretical and experimental research on the thermal energy management system of direct expansion solar heating
Yu Weifang (College of Intelligent Manufacturing, Wuxi, China + Wuxi Vocational College of Science and Technology, Wuxi, China), [email protected]
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.
