Research on operation strategy of solar assisted ground source heat pump system
摘要
Abstract
In this paper, the operating time of the solar assisted ground source heat pump system (SAGSHP system) is divided into multiple operating periods based on the difference of the meteorological conditions and heating load. The influence of operating parameters on system performance is studied with setting different operating parameters of heat collection, heat storage and heating mode of heat pump during various operating periods. And then, the optimal operating parameters of each operating period are determined. The parameters of the system performance include COP of heat pump unit, direct heat supply proportion, total power consumption of SAGSHP system, COP of SAGSHP system and so on. The simulating results of the system show that the annual heat collection of the operating strategy mode of divided period is increased by 4.0%compared to that of the normal operating mode of non-divided period. Similarly, the heat storage is increased by 7.1%, the solar direct heat supply is increased by 15.5%, and the COP of SAGSHP system is increased by 3.9%.关键词
