1、前言许多工业如化学、石油、造纸、食品等,大量的热以40～70℃的热水形式向外界排放。这种低品位热的可用性很低,如果不提高它的温度,则回收这种热量是不经济的。工业上可借助于热泵来提高这种低温热源的品位。压缩式热泵的缺点是需要高品位能量来驱动压缩机。而吸收式热泵以废热为动力,因而减少了运行成本。当然,要使制冷剂在系统中循环,少量的辅助动力仍是必需的。传统的蒸汽吸收热泵系统(VAHP)
1, Preface Many industries such as chemical, petroleum, paper, food, etc., a lot of heat to 40 ~ 70 ℃ hot water to the outside world emissions. The availability of this low-grade heat is very low and recovery of this heat is uneconomical without increasing its temperature. Industry can use the heat pump to improve the quality of this low-temperature heat source. The disadvantage of a compression heat pump is the need for high-grade energy to drive the compressor. The absorption heat pump to waste heat as the driving force, thus reducing operating costs. Of course, for the refrigerant to circulate in the system, a small amount of auxiliary power is still necessary. The traditional steam absorption heat pump system (VAHP)
