ことを特徴とする空気調和機。 It is equipped with a heating load signal output means 13 that outputs a signal corresponding to the heating load such as room temperature, and the output means 13 is connected to a rotation speed controller 10 to control the capacity of the compressor by changing the rotation speed of the compressor motor 11. In the air conditioner, the current detecting means 14 for detecting the current supplied to the compressor motor 11, the current setting means 15 for setting the upper limit value of the current supplied to the compressor motor 11, and the above-mentioned Detection means 14
and a control means 12 for comparing the output from the setting means 15 with the output from the setting means 15 and controlling the operation of the rotation speed controller 10 so that the detected current does not exceed the set value. The current setting means 15 is connected to a first current setting means 16 for setting a high current value when the floor radiant heating machine 6 is not in use, and a first current setting means 16 for setting a high current value when the floor radiant heating machine 6 is not in use. and a second current setting means 17 for setting the value, and both of the above means 16, 17
An air conditioner characterized in that a switching means 18 is provided for selectively outputting either high or low output from the control means 12 to the control means 12.
