PURPOSE:To obtain an air conditioner in which the abnormal rise of a high pressure side pressure at the time of heating can be effectively suppressed while shortening a time taken for release while reducing the frequency of the release, hence a heating efficiency can be improved and a wet vapor suction can be prevented as much as possible. CONSTITUTION:At the time of heating, when the temperature Tc of an indoor heat exchanger 5 (condenser) is raised to 60 deg.C or higher, a release signal is generated. When the temperature Tc of the exchanger 5 is dropped thereafter to less than 58 deg.C, a release cancel signal is generated. In the case of generating the release signal, the speed of an outdoor blower 6 is reduced at each predetermined time such as each one minute. The speed reducing width of the blower 6 is largely set as compared with that at the following time of decreasing. When the release cancel signal is generated, the speed reduction of the blower 6 is cancelled. |
