Working principle of heat recovery wheel

Heat recovery wheelworking principle

Working principle: Taking winter as an example, indoor return air is discharged to the outside through the upper part of the heat exchanger. At this moment, the majority of the air contained in the external atmosphere

Heat and moisture accumulate in the wheel, and only polluted air is discharged outdoors. In addition, the outdoor new heat exchanger is introduced from the lower half of the heat exchanger

Wind, when passing through a rotating wheel, captures the heat and moisture accumulated in the wheel, which is preheated and humidified. Similarly, in summer, it has pre cooling and dehumidification effects, and continues to do so

Continuously supplying fresh air indoors. That is to say, allHeat recovery wheelIt is an energy-saving device that recovers energy lost during ventilation.
