Heat Pumps
Application
The advanced heating technology used in air source heat pumps make them ideal for use in the UK's ambient temperatures hence perfect for the domestic market. Air Source heat pumps are ideal for use in a variety of house sizes or styles.
Traditionally heat pumps have been seen as only suitable for under floor heating, however with the advanced control system of the Mitsubishi Ecodan and it's ability to provide optimum variable flow temperature control, radiators can now be easily provided with the hot water they need and prove to be a very efficient option.
Performance
With conventional boilers, 1kW of input energy provides less than 1kW of output energy orheat. With air source heat pumps, every 1kW of input energy is converted into an average of 3kW of output energy or heat, making it more than three times as efficient as conventional boilers and a natural choice for low cost heating and hot water.
With the UK's ambient temperatures, our air source heat pumps are perfectly designed to operate at optimum performance throughout the year. They can generate hot water up to 60ºC, it also has the ability to operate in the unlikely event of the outside temperature plummeting to -20ºC
Technology
The technology inside the air source heat pump is similar to any domestic refrigerator, which uses a vapour compression cycle. The main components in the air source heat pump are the compressor, the expansion valve and two heat exchangers.
- Refrigerant in the evaporator is colder than the heat source. This causes the heat to move from the heat source (outside air) to the refrigerant, which then evaporates.
- This vapour then moves to the compressor and reaches a higher temperature and pressure.
- The hot vapour then enters the condenser and gives off heat as it condenses.
- The refrigerant then moves to the expansion valve; drops in temperature and pressure; and then returns to the evaporator.
