Type I Industrial Application
The Type I unit produces a high amount of medium-temperature heat from the absorber and condenser section based on a relatively smaller amount of high-temperature waste heat in the generator section and low-temperature waste heat in the evaporator section .
In this Type I application , the extracted steam at 0.5 MPa ( g ) from the power steam turbine is the driving heat source in the generator section . The water diverted from the cooling tower is the low-temperature waste heat source that is fed into the evaporator section . The heat pump delivers 90 ° C ( 194 ° F ) from the absorber and condenser section , which can be used for district heating or boiler feed water pre-heating . This application saves primary energy , reduces steam and water consumption and helps cut emissions .
With a Type I absorption heat pump , it is typical to have a heating COP of 1.7 , meaning 1.7 units of heat is obtained from the absorber and condenser with a 1.0 unit of driving heat source in the generator and . 7 units being in the evaporator section .
