Eurovent Thermal Wheel/Rotating Heat Exchanger (HRT-500~5000)


Rotary heat exchanger (wheel) is mainly used in building ventilation or in the air supply/discharge system of air conditioning equipment. The wheel transfers the energy (cold or heat) contained in exhaust air to the fresh air supplied to indoor. It's one important equipment and key technology in the field of construction energy-saving.

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 thick- ness.
 
Molecular sieve selectively absorbs moisture and expels odor by molecular lattice.
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 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 SystemUnique 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.
Purge SectorBecause 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.
 
Bearing and LubricationThe 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.
 
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.
 
Operation Control Motor voltage is 380V/3ph/50Hz, with the turbine-worm reducer, the wheel rotates at about 10 rpm steadily.
 
Standardly, we offer wheels without operation control device. However as an option, 
we offer ZK-100 intelligent controller which has following functions:
1)Various rotary speed control by instruction signal from the exterior sensor. Speed can be steplessly ad- justed.
2)Manual set of rotary speed
3)Automatic temperature sensing and running mode selection.
4)  Fault alarm and display
5)  Overload and undervoltage protection
