Heat Recovery Wheel comes under rotary air to air heat ex-changer, which consist of wheel of alluminium substrate coat-ed with desiccant which reduces the cross contaminations to minimum. The wheel comes with segmented or unsegmented options, helping easy for maintenance. The airflow across the wheel is laminar due to coating of desiccant. The wheel comes with the diameters in between 0.5m to 5m.
Heat recovery equipment for air-side equipment Technology outline & how it can save energy:(a) Thermal wheel and Desiccant total energy heat recovery wheel . Thermal wheel is a heat transfer device with a rotating wheel, which allows the sensible heat transfer between the fresh air intake and exhaust air in an AC system.
THE USE OF HEAT RECOVERY DEVICES FOR REDUCING Latent load recovery = air flow × air density × 2454 × (8) Power to operate this heat wheel = 0.186425kW (9) The equations obtained were used to build
Total-energy recovery systems not only transfer sensible heat, but latent heat as well that is, energy stored in water vapor in the air stream. Such systems raise and lower both the dry bulb and dew point of an air stream. Common examples of total-energy recovery devices include total-energy rotary heat exchangers (also known as
102.20-AG6, Air Systems - Energy Series, Energy Amount of Heat Transferred The sensible and total energy transferred by the energy recovery wheel can be calculated using Equations 2 and 3:Equation 2:Q s = H 1.08 Vmin (t1 - t3) Equation 3:Q t = H 4.5 Vmin (h1 - h3) Where:Qs = Sensible heat transferred (btu/hr) Q t= Total heat transferred (btu/hr) H = Sensible, or total effectiveness
