Our systems provide highly efficient solutions, which minimise the impact on the environment and running costs.
- A heat exchanger contains refrigerant, which is colder than the outside air. As the air passes the exchanger, the refrigerant absorbs the latent heat from the outside air and evaporates.
- The vapour passes into the compressor and is compressed, increasing its pressure and temperature, effectively concentrating the heat.
- Hot vapour is condensed in the second heat exchanger where heat is rejected and the vapour condenses back into a liquid. The rejected heat passes into the central heating and hot water system, ready for use in the home.
- The liquid refrigerant passes back through an expansion valve, ready to start the cycle again.
