Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/016918
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an air conditioner that suppresses an increase in power consumption which accompanies the starting and stopping of a compressor, and that has high energy efficiency. In response to such problem, this air conditioning device is provided with a refrigeration cycle device formed by connecting an outdoor unit equipped with a compressor and a plurality of indoor units. On the basis of the temperature difference information of an intake air temperature and a set temperature, the indoor units perform an air conditioning operation by switching between a thermo-ON operation that performs a cooling operation or a heating operation and a thermo-OFF operation that stops the cooling operation or the heating operation. If an indoor unit (A) satisfies a thermo-OFF condition by which the thermo-ON operation is switched to the thermo-OFF operation and if there is no indoor unit in the thermo-ON operation other than the indoor unit (A), the air conditioning device shifts to a start/stop control operation mode that causes any of the indoor units to perform the thermo-ON operation.
