Natural refrigerant heat pump water heaters

Heat pump water heaters using a natural refrigerant, such as CO2, propane gas or ammonia (whose global warming potential can be more than 1000 times lower than conventional refrigerants such as R134a or R410a). For heat pump CO2 water heaters, the refrigerant operates in a transcritical cycle (i.e. behaving like a gas but with the density of a liquid), which enhances energy performance.

Vapour compression packaged air conditioners

Uses vapour compression refrigeration and a refrigerant system to remove heat from a space and provide cooling. All components (evaporator coil, condenser, and compressor) are located in one cabinet, usually placed outside.

Inclined or deep horizontal wells heat pump

Closed star-shaped geo-energy inclined exchangers (vertical, deviated or deep horizontal), typically going several hundred metres deep and allowing a drastic reduction of the space footprint of geothermal heating.

State-of-the-art air-to-air heat pump

Transfer heat energy from a colder space to a warmer one, providing either heating or cooling (using either outdoor air or indoor air as a source of heat) thanks to vapour compression refrigeration and a refrigerant system. Typically more efficient than electrical resistance heaters, although efficiencies begin dropping significantly with low outside air temperature (below 5¬∞C).

Vapour compression split air conditioners

Uses vapour compression refrigeration and a refrigerant system to remove heat from a space and provide cooling. Components are split between an outdoor cabinet (condenser and compressor), and indoor cabinet (evaporator coil) and an air handler, which sends the cool air through the duct system.

Shallow ground-source heat pump

Heat pump transferring heat to or from the ground to provide cooling or heating, thanks to a ground heat exchanger buried in the ground. More energy-efficient than air-source heat pumps, especially in winter, as the underground temperature does not drop as much as other heat sources like the air or water.

Membrane heat pump

Providing cooling and dehumidification (or humidification and heating), membrane heat pumps are characterised by several permeable membranes and a vacuum pump. Separate control of sensible and latent heat.
