<p>An air conditioner exhibiting a preferred COP even under a different use condition. In a cooling medium circuit (10), a compressor (21), an outdoor heat exchanger (23), an indoor expansion valve (41, 51), and indoor heat exchanger (42, 52) are interconnected so as to circulate the cooling medium. An outdoor fan (28) sends a fluid to the outdoor heat exchanger (23). A heat exchange temperature sensor (33) detects the condensation temperature of the cooling medium. An outdoor temperature sensor (36) detects the temperature of the outdoor air subjected to heat exchange with the cooling medium in the outdoor heat exchanger (23). A control unit (8) divides the degree of supercooling of the cooling medium present near the outlet of the outdoor heat exchanger (23) by the difference between the detected condensation temperature of the cooling medium and the detected temperature of the outdoor air and controls at least one of the compressor (21), the indoor expansion valve (41, 51), and the outdoor fan (28) according to the quotient of the division used as a target value.</p> |
