本文主要以沈阳市某办公建筑的实际工程进行空气-土壤双热源热泵系统模拟研究。本系统在冬季以空气源为主要热源、土壤源为辅助热源进行供热,夏季由土壤源热泵单独制冷。本文主要应用DeST软件及TRNSYS软件对所研究工程的空气-土壤双热源热泵系统进行模拟分析,并与单一热源进行比较。在能耗方面,双热源热泵系统的全年能耗为25962.23 kWh,单一土壤源热泵系统全年能耗45573.78 kWh,双热源热泵系统相对节省了43.03%的能耗,在运行费用和节能方面,有明显的优越性及发展前景。
In this paper, the actual project of an office building in Shenyang City, air-soil dual heat pump system simulation study. The system in the winter air source as the main heat source, soil source for the auxiliary heat for heating, the ground source heat pump alone in the summer cooling. In this paper, the DeST software and TRNSYS software are used to simulate the air-soil dual heat source heat pump system under study and compared with a single heat source. In terms of energy consumption, the annual energy consumption of the dual-heat source heat pump system is 25962.23 kWh, the annual energy consumption of a single ground source heat pump system is 45573.78 kWh, and the relative energy saving of the double heat source heat pump system is 43.03%. In terms of operation cost and energy saving, There are obvious advantages and development prospects.
