燃气热泵及其它供热空调系统的能源利用分析评价

分析燃气机热泵及其它供热空调系统的能源利用的情况，及社会经济效益，指出燃气热泵系统在提高一次能源利用率，减少环境污染方面的优势，结果显示燃气机热泵的一次能源利用率最高，年单位面积供热能耗量低，而年单位面积运行能耗费用与年单位面积总成本仅次于燃煤锅炉和冷水机组方案，该文进一步提出应该按照系统消耗能源需要的治理技术和工艺情况（包括生产该能源的污染治理情况）收取系统能源消耗污染治理费，并就该项费用指标对装置经济性的影响进行分析，得出当煤的能源消耗污染治理费大于0．344元／kg时，燃气热泵的年单位面积总成本会低于所有的其它方案。

EVALUATION OF GAS-ENGINE HEAT PUMPS AND OTHERHEATING AND COOLING SYSTEMS ABOUT THEENERGY EFFICIENCY AND ECONOMIC BENEFIT

In order to analyze the energy efficiency and economic benefit of the gas engine heat pump(GEHP),the ratio of using primary energy resources,annual operating cost per unit area,and annual overall cost of six kinds of heating and cooling systems are analyzed.The results show that the GEHP has the highest primary energy efficiency,the lowest annual energy consumption per unit area,and its annual operating cost and annual overall cost per unit area are just higher than the system of coal fired boiler plus air conditioner.Improving the economic property of the products to be benefit to environment and energy saving,the authors of this paper suggest that the money that should be paid is the cost during the process of energy consumption and production (CECP)to govern emitting to environment.By analyzing the relationship between the CECP and the annual overall cost,we conclude that when the CECP is higher than 0.344 yuan per kilogram standard coal,the GEHP has the lowest annual overall cost per unit area.
