Air to water  heat pump

In terms of placement, a distinction is made between outdoor and indoor (also known as ducted) Air to Water heat pumps. Outdoor heat pumps are usually fitted with axial fans, whereas indoor heat pumps are equipped with higher pressure (eg centrifugal) fans. The latter are usually used in case of lack of outdoor space. The heat generated by the heat pump is transferred to the building by a water transfer medium, where additional units (eg fan coil, air handling unit, etc.) can be used to produce the desired temperature conditions in the spaces.

Refigirant gas ODP GWP
HFC R-410A 0 2088
HFC R-134A 0 1430
HF0 R1234ze 0 6
HFC R-513A 0 631
HFC R-407C 0 1774
R-454B 0 466

The GWP shows the amount of CO2 equivalent to the test substance in the greenhouse effect over 100 years (kgCO2 / kg). The lower the number, the less potent the greenhouse effect.

Ozone depletion is indicated by the ODP value (Ozone Depletion Potential), which can be between 0 and 1.
