介绍了一种先进的循环，通过这种循环，目前使用的H2O/LiBr空调可以切换到热泵运行模式。吸收的热量转化为高于50°C的温度，因此可用于加热。在下一个循环中，描述了将蒸汽压缩机集成到H2O/LiBr吸收系统中的过程。用内燃机驱动压缩机，并将废热送入吸收系统的发电机，可使COP（冷生产/一次能源）从目前的约1（双效吸收机或电动压缩机）增加到约1。 5.单元:SICitation:研讨会，ASHRAE交易，1985年，第91卷，pt。你好，檀香山2B

An advanced cycle is presented, by which presently used H2O/LiBr air conditioners can be switched into a heat-pump mode of operation. The heat of absorption is transformed to temperatures above 50°C, thus being usable for heating.In a further cycle, the integration of a steam compressor into a H2O/LiBr absorption system is described. Driving the compressor with a combustion engine and feeding the waste heat into the generators of the absorption system yields an increase of the COP (cold production/primary energy) from presently about 1 (for double-effect absorption machines or for electrically driven compression machines) to about 1.5.Units: SI
