PROBLEM TO BE SOLVED: To prevent the occurrence of trouble that the state of a refrigerating cycle is hardly grasped accurately, even when a set function for setting humidity in a multistage is employed, the set function is not sufficiently effectively utilized, and amenity is low. SOLUTION: This air-conditioner comprises a refirgerating cycle having a compressor 1, a four-way valve 2, an indoor heat-exchanger 5, and outdoor heat-exchanger 3 interconnected and a refirgerant having a pressure loss of a refrigerant lower than that of an R22 refrigerant, an indoor fan 6 to generate an air flow passing through the indoor heat exchanger 5, an outdoor fan 7 to generate an air flow passing through the outdoor heat-exchanger, a humidity determining part 8c to determine set humidity in a multistage and a control part 8 to control the refrigerating cycle, the indoor fan 7, or the outdoor fan 6 so that humidity is adjusted to a set value. |
