１熱交換器３の放熱量が低下し。When the air conditioner is operated for cooling, the refrigerant flows as shown by the dotted line, radiating heat in the outdoor heat exchanger 2, absorbing heat in the indoor heat exchangers 3 and 4, and cooling the indoor area. become. When the switch 11 in Fig. 2 is set to the dotted line for dehumidifying operation, the refrigerant flows as shown by the dotted line, becomes part of the first heat exchanger or condenser on the indoor side, and radiates heat, and the second heat exchanger Since it becomes part of the evaporator and simultaneously absorbs heat and dehumidifies it, a dehumidifying operation is performed in which the air inside the room is only dehumidified and the temperature does not drop. In such an air conditioner, when the temperature on the outdoor side decreases during dehumidification operation, the amount of heat released by the first heat exchanger 3 on the indoor side decreases.
室内側の温度が低下しすぎてしまうという欠点があった
。又、この第１熱交換器３の放熱量を変化させて、室内
側で吐出させる空気温度を欲求に応じて変化できないと
いう問題点もあった。The drawback was that the temperature inside the room would drop too much. Another problem is that the temperature of the air discharged indoors cannot be changed as desired by changing the amount of heat released by the first heat exchanger 3.
本発明は上記欠陥を改良するものである。 The present invention aims to improve the above deficiencies.

たものである。In other words, when the temperature on the outdoor side decreases and the amount of reheat to the indoor side decreases, or when a higher amount of reheat to the indoor side is required, by changing the time interval between operation and stop of the blower 8 on the outdoor side, This reduces heat radiation outside the room and increases heat radiation inside the room.

。By controlling the controller 13 that controls the OFF time, the operation rate of the outdoor blower 8 is changed, and as a result, the amount of heat released from the outdoor heat exchanger 2 is changed, and the amount of heat released from the outdoor side heat exchanger 2 is changed. The amount of heat dissipated from the

じ結果が得られる。As described above, the present invention has a first heat exchanger 3, a condenser and a blower 8 on the outdoor side, and a reheater on the indoor side. Second heat exchanger 4 of the cooler
In this air conditioner, which performs dehumidifying operation by providing a switch 12 for turning on and off the blower 8 on the outdoor side, the amount of reheat to the indoor side can be changed, making the air conditioner more comfortable. . In the present invention, the heat radiation amount is changed by turning on and off the outdoor fan 8 to change the air volume, but the same result can be obtained even if the rotation speed of the fan 8 is changed.
