Absorption heat pump and absorption chillers - 'sample, the generator, condenser, expansion valve, evaporator, absorber and solution of pump, the system is shown in figure 6-6-10. It, at the expense of the consumption of high heat absorption through thermodynamic cycle device to increase the heat of low temperature heat source 7 c temperature for users to use after. According to thermodynamic viewpoint, the absorption heat pump can be considered a work in between the two heat source (Th and again) engine, is to provide high quality can (1) y no compressor compression heat pump unit. As shown in figure 6-6-11, engine HM get heat from heat source (7 h) Qh, part into work that drives the pump door P learn Qo heat from low temperature heat source, and will be out of the two parts of heat, the heat engine and the pump Fei out quantity of heat Q. 'and Qh users' supply.

Under ideal conditions, according to the principle of thermodynamics, the heat balance equation for

By the above equation, the maximum working coefficient of the absorption heat pump can be obtained
