Abstract

PURPOSE: To prevent a thermostat from generating a hunting and prevent a pressure on the discharge side of a compressor from becoming too large by transmitting a frequency command wherein a frequency is higher than that of the signal of the controller of a distribution control unit only during a period for which a time from the start of a heating operation and a refrigerant temperature on the discharge side of the compressor are below a prescribed values.
CONSTITUTION: A multi-controller 2 is provided with a temperature sensor 24 for detecting a refrigerant temperature on a compressor discharge side. The multi-controller 2 releases the high frequency operation of a compressor 32 when the refrigerant temperature exceeds a given value before a time set to a timer 22 elapses. To transmit a frequency command wherein a frequency is higher than that of the signal of the signal controller 11 of an indoor unit 1A to the controller 31 of an outdoor unit 3 only during a period wherein a time from a start and a refrigerant temperature on the compressor discharge side are below prescribed values, an operation at a high frequency is released at the time when the refrigerant temperature exceeds the prescribed value. Thus, a hunting due to the repetition of the ON/OFF action of a thermostat and a too high pressure on the compressor discharge side can be prevented.
