Technical field:

Background technique:

The second type of absorption heat pump uses the temperature difference between the residual heat medium and the cooling medium as the driving force. When the driving temperature difference is large, the double-effect or multi-effect process should be used to provide the utilization rate of the low-temperature residual heat; when the temperature difference is small and the residual heat When it is rich, it should be considered to use graded condensation to increase the utilization of waste heat resources. From the perspective of working fluid, there are sub-temperature working medium and low-temperature working medium, which correspond to suitable thermodynamic parameters; thus, when the driving temperature difference exceeds the working range of a single working medium, two or two should be considered.
