Gas Absorption Heat Pumps - The technology

When a GAHP is used to heat a building, the energy is moved from a low temperature heat source and then upgraded in the heat pump so that it can be used to heat air or water inside the building.

The ambient air or ground provide an ample source of renewable energy which can be harvested and transferred to provide a building’s heating needs. 

Product features

  • Simple Process - uses refrigerants change of state from gas to liquid and back again to move heat - no requirement for electrical compressor used in a traditional heat pump.
  • Advanced absorber and generator systems transfer the refrigerant into an absorbing fluid and then liquefy it.
  • Only a small supply of energy is required to pump the refrigerant solution and circulate the air.
  • ‘Stand-alone’ package with automatic control.
  • Containerised shell protects it from the elements.

How does a GAHP work?

1. Gas burner heats
ammonia and water
solution.
3. High pressure ammonia 
liquid converted into low pressure ammonia liquid.
5. Ammonia gas absorbs into ammonia water solution. 
2. Ammonia gas enters condenser, condenses 
and releases heat.
4. Ammonia liquid 
evaporates and draws in
heat from ambient air.
6. Solution pump powers process.
