Type II Industry Application Process Heating Application
With a Type II absorption heat pump , it is typical to have a heating COP of 0.47 , meaning 0.47 units of heat is obtained from the absorber with a 1.0 unit of driving heat source in the evaporator and generator . The 0.53 units of heat rejected in the condenser can be used for other process applications .
In this Type II absorption heat pump application , the jacket water of the gas engine at 90 ° C ( 194 ° F ) is the driving heat source . The heat pump delivers 137 ° C ( 279 ° F ) from the absorber section that can be flashed in a tank to produce low-pressure steam at 0.2 MPa ( g ) for process heating . A portion of the input heat is rejected through the condenser section and is used for other purposes in the facility .
