Title:
車両用空調装置
Document Type and Number:
Japanese Patent JP7338175
Kind Code:
B2
Abstract:
To provide an air conditioner for a vehicle which reduces refrigerant passing sound.SOLUTION: An air conditioner for a vehicle includes a compressor for compressing refrigerant circulating a refrigeration cycle device, a condensation heat exchanger for condensing gas-phrase refrigerant compressed by the compressor, and an expansion valve for expanding a liquid-phase refrigerant condensed by the condensation heat exchanger. The air conditioner for a vehicle includes an evaporator for performing heat exchange of the liquid-phase refrigerant expanded by the expansion valve and air provided into a cabin to evaporate the liquid-phase refrigerant, and a refrigerant piping for connecting the compressor, the condensation heat exchanger, the expansion valve and the evaporator to cause the refrigerant to flow inside. The air conditioner for a vehicle includes a background noise information acquisition part for acquiring information of background noise, and an air conditioning control part for controlling the compressor. The air conditioning control part performs control so as to make the lower limit value of a refrigerant discharge capability of the compressor large as the background noise acquired by the background noise information acquisition part becomes small. Consequently, it is possible to acquire the air conditioner for a vehicle which reduces refrigerant passing noise.SELECTED DRAWING: Figure 3
