The thermal wheel is used to recover the energy from the exhaust air and subsequently bring down the overall cooling load.
The thermal wheels are air to air rotary heat exchanger and can recover energy up to 80% without spoiling the IAQ. The heat wheel can recover both the sensible as well as latent heat thus reducing the load on the main cooling coil by around 30 % Two basic types of Wheels are available. Sensible heat recovery wheel – for sensible heat recovery only Enthalpy heat recovery wheel – for Sensible and latent recovery The thermal wheel is a revolving cylinder divided into a number of parallel flutes.
