Title:
AIR CONDITIONING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/205576
Kind Code:
A1
Abstract:
An air conditioning apparatus comprising: a compressor; a shell temperature detection sensor that detects the shell temperature of the compressor; an outside air temperature detection sensor that detects the temperature of outside air; a memory that stores the mode of operation in effect immediately before the compressor stops; a preheating device that preheats the compressor; a control device that, when operation of the compressor has stopped, deems that the preheating of the compressor by the preheating device is unnecessary in cases in which the mode of operation in effect immediately before the compressor has stopped as stored in the memory is not air-warming mode, and in cases in which said operation mode was air-warming mode and the outside air temperature detected by the outside air temperature detection sensor is not equal to or less than a first temperature; and an outdoor unit substrate having a power supply cutoff unit that cuts off electric power supplied from a power source, the outdoor unit substrate conducting the electric power supplied from the power source to the outside air temperature detection sensor, the memory, and the shell temperature detection sensor. The control device issues an instruction for the power supply cutoff unit of the outdoor unit substrate to cut off the power supply when it has been deemed unnecessary for the compressor to be preheated by the preheating device. The power supply cutoff unit cuts off the electric power supplied to the outdoor unit substrate from the power supply in cases in which an instruction to cut off the power supply has been received from the control device.
