Working Principle
Rotary heat exchanger is composed of alveolate heat wheel, case, drive system and sealing parts.
The exhaust and outdoor air pass through half of the wheel separately, when the wheel rotates,
the heat and moisture are exchanged between the exhaust and outdoor air. The energy recovery efficiency is up to 70%~90%
Wheel Materials
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.
Wheel Construction
The wheel of the rotary heat exchanger is made of alternating layers of flat and corrugated aluminum foil to form the alveolate shape.
Various height of corrugation is available. Flat surface ensures minimum leakage. Interior spokes are used to mechanically bond the rotor’s laminations. These are threaded at the hub and welded at the periphery.
Laminar Flow Channels
The wave type structure of the wheel forms narrow channels in the direction of air flow. The air flow forms a laminar flow inside the wheel
when passing through it. When the wheel rotates, dust won’t accumulate on the channel since outdoor air and exhaust air respectively flow through the channels from two directions. This is called self cleaning.
Double Sealing System
Unique double sealing system is installed around the rotor periphery and along the central beam. The sealing materials are soft and dense of small friction and longer service life.
Bearing and Lubrication
The hub of the wheel is equipped with life-time- lubricated ball bearing or roller bearing, and with covers at both sides. No maintenance is required under normal usage.
