A new dehumidification air conditioning was put forward on the research above. The procedures were as follows. Firstly, on the basis of thermocompression air conditioning, liquid dehumidification system was added. Secondly, dehumidification solution was sprayed on the evaporator and condensator directly. The evaporator's cooling was used in dehumidification. The condensator's heat was used in the solution's regeneration. The latent heat charge and sensible heat charge were treated at the same time in this air conditioning process.
