Working Principle
Rotary heat exchanger is composed of alveolate heat wheel, case, drive system and sealing parts. The ex-
haust and outdoor air pass through half of the wheel separately, when the wheel rotates, the heat and mois-
ture are exchanged between the exhaust and outdoor air. The energy recovery efficiency is up to 70% to
90%.
Wheel materials of air to air plate heat exchanger
The sensible heat wheel is made by aluminum foils of 0.05mm thickness.
And the total heat wheel is made by aluminum foils coated with 3A molecular sieve of 0.07mm thickness.
Adhensive; aluminum foil; moisture absorption coating
Silicon gel absorbs both moisture and odor by capillarity.
Molecular sieve selectively absorbs moisture and expels odor by molecular lattice.
Wheel Construction of wheel type heat exchanger
1, The wheel of the rotary heat exchanger is made of alternating layers of flat and corrugated aluminum foil to form the alveolate shape.
2, Various height of corrugation is available.
3, Flat surface ensures minimum leakage.
4, Interior spokes are used to mechanically bond the rotor’s laminations. These are threaded at the hub and welded at the periphery.
The wheels can be divided into small sectors, convenient for transporting
