Sorption rotary heat exchangers
Air flow through rotary heat exchanger
Operation
Rotary heat exchangers transfer energy through a rotating storage mass, which is alternately heated by one air stream and cooled by the other. They can transfer both temperature and humidity between air streams.
The storage mass consists of aluminium foil. A smooth and a corrugated foil are wound on top of each other to form a wheel of sinusoidal channels. Warm air and cold air flow through these alternately and thus transfer the heat between the two air streams.
Their storage mass is largely or even completely coated with a hydrophilic material. Therefore, they transfer humidity between the air streams all year round. The sorption coating guarantees maximum humidity transfer for all seasons. In summer operation, the supply air is not only precooled, but also significantly dehumidified at the same time. This in turn reduces the subsequent cooling demand. As a result, the output of the cooling units does not need to be as high and their dimensions can be reduced, thereby reducing both running and investment costs.

Muonio (HM1)
The aluminium foil used for the storage mass is completely coated with molecular sieve 3 Å. This makes Muonio exchangers a high-performance model. The sorption coating guarantees maximum humidity efficiency throughout the year.
In summer operation, the supply air is dried. The cooling requirement to be covered by a cooling unit is considerably reduced. This saves both investment costs and energy costs for cooling. In winter operation, humidity transfer improves the indoor climate.

Einsatzbereiche
Die Sorptionsbeschichtung bewirkt eine ganzjährig hohe Feuchteübertragung. Dadurch reduziert sich im Sommer der Kühlbedarf, der sonst durch Kältemaschinen gedeckt werden muss. Im Winter verbessert sich signifikant das Raumklima. So eignet sich der Sorption Sorptionswärmetauscher ideal für den Einsatz in Lüftungsanlagen mit mechanischer Kühlung.
