Air-Source Heat Pumps

Innovations in energy efficient design and the pioneering introduction of new refrigerants have produced systems that are better for the environment and comply with all current and planned legislative demands. In addition, with energy tax beginning to impact on business, air conditioning and ventilation is a real investment for the future.

How it works:

The technology inside the air source heat pump is similar to any domestic refrigerator, using a vapour compression cycle. The main components in the air source heat pump are the compressor, the expansion valve and two heat exchanges.

  1. Refrigerant in the evaporator is colder than the heat source, causing the heat to move from the heat source to the refrigerant, which then evaporates.
  2. This vapour moves to the compressor and reaches a higher temperature and pressure.
  3. The hot vapour now enters the condenser and gives off heat as it condenses.
  4. The refrigerant then moves to the expansion valve; drops in temperature and pressure; and returns to the evaporator.
