第１項記載の空気調和機。[Scope of Claim for Utility Model Registration] (1) In a heat pump type air conditioner, a rotation prevention means is provided to restrict rotation of an evaporator fan that blows air to an evaporator installed in an outdoor unit only during heating operation. An air conditioner characterized in that heat radiation from the evaporator is prevented by configuring the evaporator fan so that it does not rotate even when wind blows in from the outside. (2) A practical application characterized in that the rotation stopping means is constituted by a friction body movable in the axial direction of the evaporator fan motor during heating operation, and means for pressing the friction body against the evaporator fan. An air conditioner according to claim 1 of the patent registration claim. (3) The air conditioner according to claim 1, wherein the rotation restraining means is constituted by a drive circuit that supplies a restraining waveform output to the evaporator fan motor.
