In a heat pump air conditioner that consists of an outdoor unit consisting of a compressor, an outdoor heat exchanger, and a pressure reducing device, and an indoor unit consisting of an indoor heat exchanger, fan, and expansion valve, the indoor unit is equipped with an indoor temperature detector. A rotation speed control is installed to adjust the air volume of the fan in response to the output of the indoor temperature sensor, and a pressure transducer is installed in the refrigerant piping on the suction side and discharge side of the compressor of the outdoor unit. In order to keep the pressure constant on the discharge side and on the suction side during cooling, an engine or an electric motor with variable rotation speed is installed to control the rotation speed of the compressor.
（作用）
前記技術的手段は次のように作用する。すなわち室内ユ

温より高い場合には、モータの回転数をアップし、風量
を多くして室温を下げ調整するもので、室温を高（する
場合には、ファンの回転を低下せしめるものである。(Operation) The technical means operates as follows. In other words, in an indoor unit, when heat is exchanged by a fan in a heat exchanger, during cooling, an indoor temperature sensor measures the temperature near the air blown from the fan, and if the temperature is higher than the preset room temperature, the motor This is a device that lowers and adjusts the room temperature by increasing the fan rotation speed and air volume.

は、圧縮機の回転を下げて冷媒の吸入圧力を上げる、こ
の様に室内ユニットが動作する時、ファンの回転数を上
げると、室内熱交換器での吸熱量が上昇するため蒸発温
度が高くなる。In addition, in the outdoor unit, if the refrigerant pressure in the refrigerant piping on the suction side is lower than a predetermined constant value, the rotation of the compressor is lowered and the refrigerant suction pressure is increased. When the rotation speed of the fan is increased, the amount of heat absorbed by the indoor heat exchanger increases, resulting in a higher evaporation temperature.
これは圧縮機の吸入圧力の上昇という形で表われるので
、この圧力を設定値に保つべく回転数制御装置において
原動機の回転数を上昇させるものである。This appears in the form of an increase in the suction pressure of the compressor, so in order to maintain this pressure at a set value, the rotation speed control device increases the rotation speed of the prime mover.

る。Also, during heating, if the indoor temperature drops, the rotation speed of the indoor fan is increased to increase the amount of heat exchange and raise the room temperature. At this time, the condensation temperature in the indoor heat exchanger decreases, so the compressor discharge pressure also begins to decrease. In contrast, the rotational speed control device increases the rotational speed of the prime mover and keeps the discharge pressure constant.
