摘要
热泵是一种节能型加热设备,其性能系数远高于普通锅炉装置.燃气发动机热泵除能保证一般热泵功能外,还能利用发动机余热,这样既能提高热泵运转时的性能系数,又能克服热泵在环境低温时加热性能下降的缺点.随着我国天然气的“西气东输”工程的实现,天然气作为一种能源可以分担相应的空调负荷份额.燃气发动机热泵将发挥其相应的作用.文中介绍燃气发动机热泵的工作原理,其热效率分析,特性及其在各种不同情况下的应用实例.
Heat pump is a kind of heating equipment for energy-saving purpose. Its performance coefficient is much higher than common furnace equipment. Heat pump for gas engine not only can ensure the functions of common heat pump, but also can utilize residual heat energy of the engine. Thus, the performance coefficient of the heat pump during operation is improved, and the disadvantage of the heat pump under low temperature, which is its heating performance decreases, is remedied. With the realization of 揥estern Gas Transported to the East Project?in our country, natural gas can be used to share some air-conditioning loads. Heat pump for gas engine will play a certain role. This paper introduces the work principles, thermal efficiency analysis, performances and application examples under different conditions of heat pump for gas engine.
