讨论了一种用于美国轻型商业应用的高效天然气发动机驱动热泵的开发。讨论操作的基本原则以及设计注意事项。声明通过环境室测试实现的产品目标包括95华氏度ARI性能系数（CoP）评级0.9和47华氏度ARI CoP评级1.8。讨论了现场测试结果，根据气候、应用和恒温器设定点，确定了加热COP在1.2到1.5之间，冷却COP在0.89到1.1之间的高季节性运行效率。 坚持认为，这项技术代表了空间调节技术的下一个合乎逻辑的进步，并为客户以及燃气和电力设施提供了好处。关键词:美国，测试，加热，冷却，热泵，燃气机热泵，商用，性能系数，空调引用:ASHRAE Trans。1992年，第98卷，第1部分，论文编号AN-92-10-4，994-1000，图10，表1，参考文献。

Discusses the development of a high-efficiency natural gas engine-driven heat pump for light commercial U.S. applications. Discusses basic principles of operation as well as design considerations. States that product goals achieved through environmental chamber testing include a 95degF ARI coefficient of performance (CoP) rating of 0.9 and a 47degF ARI CoP rating of 1.8. Discusses field test results, which confirm high seasonal operating efficiencies with heating CoPs ranging between 1.2 and 1.5 and cooling CoPs ranging from 0.89 to 1.1, depending on climate, application and thermostat set point. Maintains that this technology represents the next logical advance in space conditioning technology and offers benefits to the customer and gas and electric utilities.KEYWORDS: USA, testing, heating, cooling, heat pumps, gas engine heat pumps, commercial, coefficient of performance, air conditioning
