Standard: counter-current heat exchanger
New: enthalpy heat exchanger solution
New: combination heat exchanger made up of an enthalpy heat exchanger + Airmaster’s standard counter-current heat exchanger.
The enthalpy solution is particularly suited for extremely cold climates such as northernmost Scandinavia or mountainous regions such as the Norwegian interior or the Alps.
A combination heat exchanger is a cross between these two types, meaning that it has a higher impact on temperature than an enthalpy-only exchanger but a reduced effect on humidity levels.
The combination heat exchanger is ideal for inland regions of Central Europe where, although cold, dry periods can occur, the climate is not considered extreme.
The combination heat exchanger is also ideal for coastal areas with a moderate climate if you want to be certain of maintaining a higher-than-normal indoor relative humidity (over 40%) at all times.
An enthalpy heat exchanger is a heat recovery unit that transfers moisture between supply air and exhaust air.
The moisture is transferred by means of osmosis through a polymer membrane with a pore structure. The polymer membrane keeps supply air separate from exhaust air, just like Airmaster’s other heat exchangers.
This prevents the transfer of unpleasant odours or contamination.
Due to the lower temperature efficiency ratio of the enthalpy exchangers, the maximum output of an enthalpy-only exchanger is lower for AM 150 and AM 300 to comply with Ecodesign Directive requirements. Otherwise, the air handling units operate normally.
Maximum output of an enthalpy-only exchanger:
A combination heat exchanger can maintain these normal outputs for all Airmaster air handling units.
