Presents a fresh air handling solution with liquid desiccant total heat recovery combined heat pump system. Experiment results in a hospital show that the EER of the unit is 6.3 to 7.3 under summer conditions and 4.7 to 5.0 under winter conditions. Liquid desiccant can remove indoor pollutants in the air, avoiding cross contamination between air streams.
