Design of a New Solar-powered Combined Heating and Cooling System
-
Abstract
A new solar-powered combined heating and cooling system is designed based on the concept of energy saving and environmental protection, this system has high efficiency which use semiconductor chilling plate powered by solar energy to produce refrigenation effect, and the waste heat is used to supply domestic hot water. Theoretical calculation and numerical simulation are finished based on energy balance and heat transfer theory, the results shows that this system can realize the function of the refrigeration and hot water supply, which COP is 0.7 and energy utilization efficiency is 73.5%.
