How ASHP works

Air Sourced Heat Pumps are electrical devices that extracts heat from ambient air and transfers it to another place.

The Heat Pump works by transferring heat via a circulation of the coolant via a cycle of evaporation and condensation. Depending on how it is designed, these pumps can either discharge Hot Water, Hot Air, or even Cold Air.

There are 4 main components to the Heat Pump:

  1. The evaporator houses the refrigerant that is maintained at a temperature lower that the outside air. This causes heat to be transferred to the refrigerant, thus causing it to evaporate
  1. The evaporated vapour moves to the compressor and reaches a higher temperature and pressure
  1. The heated vapour enters the condensor and transfers heat to the medium to be heated during the condensation process
  1. The condensed refrigerant moves to the expansion valve and undergoes a drop in pressure and temperature before returning to the evaporator again

These 4 main components are the basis of our range of products.
