項(1)記載の空気調和機の運転制御装置。[Claims for Utility Model Registration] (1) An indoor heat exchanger, a pressure reducing device, an outdoor heat exchanger, a compressor, an indoor blower, an outdoor blower, and an inverter circuit that performs variable capacity control of the compressor. The air conditioner equipped with the above-mentioned air conditioner has a 24-hour timer that operates according to the time when the air conditioner starts operating, and a light detection element that is attached to the outdoor unit and detects the brightness outside.
An operation control device for an air conditioner, characterized in that the operating frequency of the compressor is lowered one step below the rated frequency to switch to silent operation after checking the condition. (2) While the air conditioner is running silently, the operating frequency of the compressor is returned to the vicinity of the rated frequency in response to changes in air volume or indoor temperature settings, and the operation is switched to normal operation, and after a predetermined period of time, a 24-hour timer is set. The air conditioner according to claim (1), wherein the "nighttime" condition is confirmed by the and the photodetection element, and the operating frequency of the compressor is lowered by one step below the rated frequency to switch to silent operation. Operation control device.
