一种排热风的空气调节器，包括一压缩机；一四向阀；一冷凝器；一膨胀装置；一蒸发器；以及一蓄热器，它还包括一安放在膨胀装置的出口侧并彼此相连通的辅助蒸发器；以及一安装在辅助蒸发器的入口和冷凝器之间并与它们相连通的支路管，只有当蒸发温度低于预定温度时，支路管才开通。

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.
