Chillers and Heat Pumps | Absorption Chillers and Heat Pumps
Type I
Flexible Operating Envelope
The Type I heat pump , also referred to as a heat amplifier , is driven by a high-temperature waste heat source in the generator section . The low-temperature waste heat source is fed into the evaporator section . With these two heat sources , the Type I heat pump amplifies and provides useful medium temperature heat from the absorber and condenser section .
How it Works
Medium-temperature heating water supply up to 95 ° C / 203 ° F for various applications
Condenser Generator
High-temperature driving waste heat source such as steam 2-8 bar ( g ) / 30-120 psig or Exhaust Gas / Direct Fired / Hot Water
Exhaust Gas / Direct Fired / Hot Water Low-temperature waste heat source typically 30 ° C / 86 ° F - 50 ° C / 122 ° F
Evaporator Absorber
Return heating water from application
Heat Balance
Compared to the typical steam boiler ’ s 0.93 Coefficient of Performance ( COP ), the Type I unit provides a COP as high as 1.7 *, delivering up to 95 ° C ( 203 ° F ) hot water for various heating applications . This unit also provides a good turndown over a range of heating loads .
