Twin Wheel system humidity control and energy saving

The Twin Wheel might not be as important to humanity

as the wheel. But within the air treatment business we

still consider this system a landmark innovation, and it

creates a high indoor air quality as well as energy

savings for the benefi t of our common environment.

When outdoor air is warmer thanthe exhaust airflow there is a need

for cooling. The hygroscopicrotor then reduces temperature ofthe incoming air. Simultaneouslyit transfers moisture from the in-bound to the outbound air flows(in cases where absolute humi-dity is higher outdoors)

After passing through the hygro-scopic rotor the air passes through

the cooling coil, where the temp-erature is reduced further andmoisture is condensated downto required levels. Since the airhas already been cooled by thehygroscopic rotor, the demandfor cooling is lowered. The savingcan be up to 50% of the nominalrequired cooling effect, while at thesame time the need for a followingre-heating battery in most casesdisappear.

The now dehumidified and coo-led air continues to the sensible

rotor, where heat from exhaustair is recovered and used to re-heat it. The air then is suppliedto the building, whith controlledlevels on both temperature andhumidity.Note that the temperatureexchange in the sensible rotor,where exhaust air is cooled,further improves the coolingrecovery of exhaust air in thehygroscopic rotor!

Twin Wheel advantages in overview

The Twin Wheel system contains three main parts;

the hygroscopic rotor, a cooling coil and a sensible rotor.
