以天然气为能源，用燃气机代替电动机驱动压缩机并充分利用发动机废热、工业余热以及低品位环境热量的采暖、空调装置——燃气压缩式热泵近年来发展迅速。美国燃气设备的总装机容量已达到1．2GW，日本燃气机热泵占全部燃气制冷设备的29％，总装机容量大约1GW，燃气机热泵在英国、法国、德国、瑞士等都得到了较快的发展与应用。中研究了以天然气为驱动能源的压缩式热泵的特点及能量利用率，分析并测试了该系统的运行特性及交工况特性，进行了各种工况及转速下的实验研究。结果表明，该系统具有较好的部分负荷特性、一次能源利用率及交工况特性，为一种绿色高效的供热空调系统。

Research of Heating and Cooling System Driven by Natural Gas

??Taking natural gas as an energy source,the heating and air conditioning system??the heat pumps of gas compression model,which use gas turbines instead of electric motors to drive compressors and make good use of the waste heat from engine the industrial residual heat and the environmental heat with low grade,have been developed rapidly at resent years.The total installed volume of combustible gas facilities has reached to 1.2 GW in USA.The heat pumps of gas turbine have accounted for 29% of total cooling facilities droved by combustible gas engine,and the total installed volume is about 1 GW in Japan.Also,the heat pumps of gas turbine are developed and utilized rapidly in UK,France,German,and Switzerland,etc.The article discusses the characteristics and the energy efficiency of the heat pumps of compression type droved by combustible gas,analyzes and tests the features of the system under different operating and speed conditions,The research results show that the system has good operating behaviors and higher energy efficiency and is a heating air conditioning one with environment-friend and high efficiency.
