Abstract

Abstract:

An indirect expansion solar heat pump system is a novel and efficient way to comprehensively utilize solar energy resources. To investigate the impact of different operation modes on the performance of an indirect expansion photovoltaic and photothermal（PV/T） integrated heat pump heating system in winter，a simulation model of the system was established on the Matlab/Simulink platform based on energy balance. Taking the environmental data from Baiyin area as the example，the operation status of the integrated heating system under different operating modes was analyzed. The heating performance of solar heat pumps is better than that of air source heat pumps under the same heating power，and the time control mode performs better than temperature control mode. In the time control mode，taking solar radiation as the control objective is conducive to showing the excellent heating performance and energy utilization efficiency of solar heat pumps.

Key words: solar heat pump, air source heat pump, heating method, performance, simulation
