A normal heat pump air conditioner needs condensation dehumidification

leading to low energy efficiency. To improve the energy efficiency

a novel integrated dehumidification heat pump air-condition cycle

based on a desiccant-coated heat exchanger

is presented in this paper. Through the establishment of experiment table

the performance under summer condition of the novel cycle is tested and the influence of key operational parameters are analyzed. The results show that the novel integrated dehumidification heat pump air-condition cycle has good performance: the dehumidification quantity can reach 7.9 g/kg

and the coefficient of performance（COP）of the system can reach 5.2. The change in the temperature of fresh air and return air has influence on the temperature of supply air and COP. The change in humidity of the fresh air and return air has also influence on the temperature and humidity of the supply air

the dehumidification quantity

and COP.
