<p>An air conditioning device includes: a heat pump freezing cycle formed by connecting a compressor (1), a four-way valve (2), an indoor heat exchanger (3), a pressure reducer (4), and an outdoor heat exchanger (5) by a coolant circuit; an indoor fan (7) which performs heat exchange between the indoor heat exchanger (3) and the indoor air; an outdoor fan (8) which performs heat exchange between the outdoor heat exchanger (5) and the outdoor air; and an outdoor temperature detection means (6) which detects the outdoor temperature. Moreover, when defrosting the outdoor heat exchanger (5), the compressor (1) is stopped and the outdoor fan (8) is rotated if the outdoor temperature detected by the outdoor temperature sensor (6) exceeds a predetermined value.</p> |
