LIQUID DESICCANT DEHUMIDIFIER AND AIR CONDITIONER

摘要

The present invention provides a liquid desiccant dehumidifier (200) and a liquid desiccant air conditioner (10) including an absorption air conditioner and a liquid desiccant dehumidifier. The dehumidifier includes a liquid desiccant absorber (12) for absorbing moisture contained in ambient air entering the dehumidifier and passing through the desiccant absorber. A boiler (34) is provided for boiling partially preheated dilute liquid desiccant to evaporate moisture to reconstitute the liquid desiccant into concentrated liquid desiccant. A first heat exchanger (58) fluidly communicates with the desiccant absorber and a second heat exchanger (66). The first heat exchanger is operable to transfer heat from the concentrated liquid desiccant to the dilute liquid desiccant directed to the first heat exchanger (58) from the desiccant absorber (12) to raise the temperature of the dilute liquid desiccant to a first temperature. A condenser (86) fluidly communicates with the boiler (34) to receive steam generated by boiling the liquid desiccant in the boiler, and with the first heat exchanger to receive partially heated dilute liquid desiccant from the first heat exchanger at the first temperature. A second heat exchanger (66) fluidly communicates with the condenser, the boiler and the first heat exchanger (58).
