Abstract:
An air conditioning system comprising: a desiccant for adsorbing moisture from process air, and a heat pump, including a compressor, that operates by using process air as a low-temperature heat source and regeneration air as a high-temperature heat source so as to supply heat to regeneration air for regenerating said desiccant;wherein a high-temperature heat source heat exchanger, for exchanging heat with pre-desiccant regeneration air and refrigerant, comprises a plurality of sections divided along an air flow direction, and regeneration air passes said sections in an opposite order to that of refrigerant, andwherein, in said high-temperature heat source heat exchanger said sections include, in series, a refrigerant sensible heat transfer section, a refrigerant condensation heat transfer section, a refrigerant constriction device, and a reduced-pressure refrigerant condensation heat transfer section for counter-flow transfer of heat between said refrigerant and said pre-desiccant regeneration air.
