Résumé

This study proposed a novel hybrid no-frost air source heat pump(ASHP) combined with membrane-based liquid desiccant dehumidification and humidification. Liquid-to-air membrane dehumidifier is used to dehumidify the air before entering the outdoor evaporator in the proposed system so that frosting can be prevented. Diluted solution is regenerated to humidify the supply air via the liquid-to-air membrane regenerator,which can overcome the droplets carry-over problem in the liquid-to-air energy exchanger. Mathematical models are developed to study the system performance under different climatic conditions. Moreover, the comparison between the novel system and conventional reverse-cycle defrosting ASHP is performed. Results show that the COPsen and the COPtot of the novel system are at least 37.7% and 64.3% higher than that of the COPreverse of conventional defrosting heat pump in the variation ranges of the analyzed parameters, respectively.
