PROBLEM TO BE SOLVED: To provide an air-conditioner for actualizing an improved pump life, reduced noises and a smaller size and lower cost of pump motor while suppressing the temperature rise of a pump independently of temperature characteristic of oxygen enrichment. SOLUTION: The air-conditioner comprises the pump for separating oxygen from nitrogen in air, generating a pressure difference between an oxygen enrichment membrane permeable to oxygen and an oxygen transmitting side and carrying oxygen, a driving means for driving it, a current detecting means for detecting an operating current in the air-conditioner, a current storage means for storing a preset current, a central processing unit for giving the driving means a signal for a current value detected by the current detecting means in accordance with the current stored in the preset current storage means, and a blowing means provided on an oxygen non-transmitting side for exhausting nitrogen.
