摘要
地源热泵多联机空调系统是以地源热泵作为冷热源,直接蒸发式多联机机组作为室内末端的一种新的节能技术.以天津市某办公楼的地源热泵多联机系统为研究对象,通过能耗、初投资、运行费用、维护修理费用以及敏感性和CO2排放量分析,得出在设备使用年限内,地源热泵多联机系统较传统的风冷多联机系统,6年即可回收成本;较地源热泵加风机盘管系统,尽管首年总费用高6.9%,但是LCC费用涨幅较小,11年可以回收成本;相比其他两种系统,地源热泵多联机系统受利息率和物价上升率变化影响最小,其利润风险最小.
Variable Refrigerant Volume Ground Source Heat Pump（VRV-GSHP hereinafter） is a new energy-saving technology, using ground source beat pump as a heat source, and direct evaporative multi-line units as indoor terminal devices. An office building of Tianjin is selected as representative building, and VRV-GSHP system is compared by with two other traditional air conditioning systems. According to the comparison between VRV-GSHP system and other systems in energy consumption, initial costs, operation costs and maintenance and repair costs, the economy of the VRV GSHP system is elicited.
