Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/021574
Kind Code:
A1
Abstract:
This air conditioning device is provided with: an indoor unit disposed in a space being air-conditioned and having an indoor heat exchanger and an indoor fan for blowing air to the indoor heat exchanger; an outdoor unit having a compressor; a room temperature sensor for sensing the room temperature in the space being air-conditioned; and, a control device for performing control to increase or decrease the compressor frequency of the compressor with a control width based on the difference between the room temperature sensed by the room temperature sensor and a set temperature, the control device performing a normal operation for controlling the compressor by setting the control width to a first control width when the compressor frequency exceeds a preset set frequency. The control device performs a low-capacity operation for controlling the compressor by setting the control width to a second control width smaller than the first control width when the compressor frequency is equal to or less than the set frequency and the rotational speed of the indoor fan exceeds a preset set rotational speed, and performs a low-air-volume low-capacity operation for controlling the compressor by setting the control width to a third control width smaller than the second control width when the compressor frequency is equal to or less than the set frequency and the rotational speed of the indoor fan is equal to or less than the set rotational speed.
