とする空気調和機の制御装置。 In an inverter-driven heat pump air conditioner, detects the current flowing through the bypass circuit with an on-off valve installed between the high-pressure side circuit and the low-pressure side circuit during heating, and the air conditioner power supply circuit. The current detection unit compares a voltage proportional to the current value detected by the current detection unit with two different reference voltages, high and low, and compares the higher reference voltage with the voltage proportional to the detected current value to an air conditioner comprising control means for controlling the frequency of the power supply to the air conditioner, and controlling the opening/closing valve by comparing a lower reference voltage with a voltage proportional to the detected current value. control device.
