摘要：

间接膨胀式太阳能热泵系统是一种新颖的综合利用太阳能资源的高效途径。为探究冬季条件下多系统运行方式对间接膨胀式光伏光热（PV/T）一体化热泵供暖系统运行性能的影响，基于能量平衡原理在Matlab/Simulink平台上建立了系统的仿真模型。根据白银地区的环境数据，分析了冬季供暖状况下，综合供暖系统不同运行方式下的运行状况。结果表明，相同供热功率下太阳能热泵的供暖情况优于空气源热泵的供暖情况，而且时间控制运行模式较温度控制运行模式有较好表现。时间控制运行模式中，以太阳辐射为控制标准的、利于太阳能热泵运行的运行模式有优秀的供暖效果和能源利用率。

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
