WORKING PRINCIPLE of Eurovent HRW
Air to Air Heat Exchanger Rotary Heat Exchanger
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% to 90%.

WHEEL MATERIAL

The sensible heat wheel is made by aluminum foils of 0.05mm thickness.
The total heat wheel is made by aluminum foils coated with 3A molecular sieve of 0.07mm thickness.
Plate frame is made of aluzinc.

TECHNICAL SUMMARIZATION

Driving System
The wheel is drove to rotate by this system. The drive system is composed of motor, turbine-worm reducer, belt pulley and V belt. The motor is installed on the special bracket tension- ing by the spring, it can ensure the gradually loose of V-belt in case of sudden stop.

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.

Installation Types and Motor Position
The motor is installed at the corner of the rotary heat exchanger, the position of the corner is marked from no. 1 to 4, and the motor positions is optional.

Laminar Flow Channels
The wave type structure of the wheel forms narrow chan- nels 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 RO- tor periphery and along the central beam. The sealing materials are soft and dense of small friction and longer service life.

Purge Sector
Because of the structure of rotary heat exchanger, the outdoor air and exhaust air will mix. According to the air velocity, wheel rotating speed and direction, purge sector is installed to prevent the exhaust air from entering the outdoor air.

The purge sector enables a small fraction of outdoor air to blow back the exhaust air in the alveolate holes to its side. A minimum pressure difference of 200PA between the outdoor air side and the exhaust air side is required to ensure the cleaning effectiveness.

With all conditions provided, the sector can ensure a leakage below 0.3% from exhaust air to outdoor air.
