In order to compensate the poor performance on building envelopes, it seems to be tough to keep the hygrothermal IAQ by a residential air-conditioner as the primary equipment. Since the proper latent heat load processing makes the indoor air overcooled. Otherwise the partial processing of the dehumidification load leave behind the humid indoor air. For the improvement of the hygrothermal IAQ and the reduction of HVAC loads, the residential heat pump desiccant ventilation system is expected for
