Abstract:

To further improve the utilization efficiency of solar energy and the performance of solar heat pump heating systems, a new heating mode of a solar air-source heat pump(SASHP)is proposed, and the characteristics and performance of the heat pump part of this new heating system are studied.Based on a SASHP with 10 kW, the mathematical model of this system is built, and the characteristics and performance are concluded from the simulation analysis at different environmental temperatures and output water temperatures.The results show that the performance of heat pumps can be greatly improved based on the new SASHP.When the environmental temperature is 7 ℃, the coefficient of performance(COP)of the air-source heat pump(ASHP)can be increased by 26% at most.This paper sets up a base for further study on the heating system with this new SASHP in the heating season.
