Air Source Heat Pumps

NFH-air-source-heat-pump

Air Source heating systems are more than capable of delivering all of your home or office’s heating and hot water requirements throughout the year – even when the temperature outside is down to -20°C.  Heat pumps work using a very straight forward process:

  • Extract thermal energy from the outside air
  • Refrigerant liquid in an outdoor unit absorbs the energy and the liquid evaporates into vapour
  • The vapour is compressed to increase its temperature
  • The vapour is then condensed back to a liquid, releasing its heat into your heating system
  • The refrigerant liquid is circulated back to start the process all over again A heat pump only needs a heat source (the outside air), two heat exchangers (one to absorb and another one to release heat) and a relatively small amount of drive energy to keep the system going. A heat pump extracts thermal energy from the environment. In the case of Daikin Altherma the source is the outside air.

The pump extracts the energy at a certain temperature, increases that temperature and then releases it into a medium which is the water running to your low temperature radiators, under floor heating system or fan coil units. Between those two media the heat is moved by means of a working fluid.

Compressor – the essence of heat pumps

As the working fluid passes through the evaporator and extracts heat from the air, it turns into a gas. This is where the compressor comes in. When you compress a gas the temperature rises (for example if you inflate the tyre of your bicycle, you can feel the air inside warming up through the rubber). Inside your house the second heat exchange takes place when the compressed gas enters the condenser, a surface which is colder than the gas itself. Finally, the gas condenses and releases its heat – this heat then warms up your house.

Less energy, pleasant warmth in the home

Air Source heat pumps are up to 5 times more efficient than a traditional heating system based on fossil fuels or electricity. By making use of the heat in the outside air, you use much less energy while still enjoying a stable and pleasant level of comfort. Daikin Altherma provides energy efficient, eco-friendly heating.

Minimal installation cost

Air Source heat pumps take heat form the air. No digging or excavation works are required. Both the outdoor and indoor units are compact. The external unit can be located easily outside any building, including flats. Without flames or fumes, there is no need for a chimney or constant ventilation in the room where the indoor hydrobox unit is installed.

Flexible configurations

Air Source heat pumps can be configured for use in both new and refurbishment applications, and connects to standard low temperature radiators, underfloor heating or fan coil units. If you already have a heating system, there is no need to change it all.  Air Source heat pumps satisfy your heating requirements and can also supply your sanitary hot water. They also come with a cooling option for hot summer days. Air Source heat pumps work without oil, gas or other hazardous substances – reducing potential risk that goes together. Moreover, you don’t need a gas connection or a fuel tank, so no risk of intoxication, smell or pollution from leaking tanks.
