PROBLEM TO BE SOLVED: To improve efficiency of a humidifier, by reducing input to a compressor, in the humidifier for heating and cooling a refrigerant by performing a refrigerating cycle. SOLUTION: First and second absorption heat exchangers 31 and 32 are arranged in a refrigerant circuit 15 of the humidifier 10. The refrigerant circuit 15 alternately performs operation that one of the first and second absorption heat exchangers 31 and 32 becomes a condenser and the other becomes an evaporator and operation that the other becomes the condenser and one becomes the evaporator. The humidifier 10 humidifies second air by the absorption heat exchangers 31 and 32 becoming the condenser, and dehumidifies first air by the absorption heat exchangers 31 and 32 becoming the evaporator, respectively. The humidifier 10 in humidifying operation supplies the humidified second air indoors, and exhausts the dehumidified first air outdoors. In the refrigerant circuit 15 in humidifying operation, an auxiliary heat exchanger 35 functions as the evaporator. This auxiliary heat exchanger 35 evaporates the refrigerant by absorbing heat from the first air exhausted outdoors. COPYRIGHT: (C)2006,JPO&NCIPI |
