摘　　要：为了节能减排,同时保证系统的经济可行性,提出了一种光伏和燃气机热泵联合供能的办公建筑供能方案,对系统工作原理和季节性能进行了分析.以传统分供系统为参照对象,提出了技术、环境和经济3方面的评价指标;以某一典型办公建筑在4个不同地区的全年冷热电需求为基础,设计了传统分供系统和光伏与燃气机热泵联合供能系统,从技术、环境和经济角度,分析和比较了两者的性能.结果表明:与传统供能系统相比,新系统在4个典型地区的平均一次能源节约率达到34.6%,,在4个地区的CO_2、SO_2、R11和PM2.5的平均当量减排率分别为39.4%,、50.4%,、50.4%,和50.9%,,相对投资回报年限大约为4~5年.In order to save energy,reduce emission and ensure the economic feasibility of systems simultaneously,a photovoltaic power system-combined gas engine heat pump(GP)system for energy supply of office building scheme was presented in this paper. The working principle and seasonal performance of the system were analyzed. In comparison with a traditional separation production(SP)system,the technological,environmental and economical evaluation criteria were put forward. A typical office building in four different regions was selected as a case to design the SP system and GP system. The performance of both systems was analyzed and compared from the perspective of technology,environment and economy. The results show that compared with SP system,in four typical regions,the new system has an average primary energy saving ratio of 34.6%,and its CO2,SO2,R11 and PM2.5 equivalent emission reduction rates reach 39.4%,,50.4%,,50.4%, and 50.9%,,respectively. Meanwhile,its relative payback period is about 4—5 years.
