Abstract
Clean air heat pump (CAHP) is a new technology that combines air cleaning with hygrothermal control of ventilation air. In CAHP, a regenerative desiccant wheel is used for moisture control and air cleaning. This study investigated experimentally the air cleaning performance of a desiccant wheel when it was regenerated by polluted air. The experiment was conducted in a laboratory by testing air cleaning efficiency of a CAHP using two pure chemicals - toluene and acetone as air pollutants. The results showed that the single-pass air cleaning efficiency of the CAHP remained above 40% when it was regenerated by polluted air. Although the efficiency decreased around 10% when the desiccant wheel was regenerated by polluted air compared to the value obtained when it was regenerated by cleaning outdoor air, the results suggested that using rejected indoor air for regenerating the desiccant wheel is worthwhile considering its significant effect on energy saving.
