Title:
VEHICULAR AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/047562
Kind Code:
A1
Abstract:
This vehicular air-conditioning device has an inside temperature detecting unit 32, an indoor air-conditioning unit, and an air-conditioning control unit 30. The inside temperature detecting unit detects an inside temperature (Tr). The indoor air-conditioning unit is provided with: a temperature adjusting part 10 for adjusting the temperature in a cabin; and a blowing part (1) for blowing air in the cabin. The air-conditioning control unit has automatic control parts (S2, S3, S4, S5, S6), an open signal detecting part (S7), thermal load determining parts (S8, S10), and power saving control parts (S9, S11). The automatic control parts perform an automatic control that automatically adjusts the operation of the indoor air-conditioning unit according to the detected inside temperature. The open signal detecting part detects an open signal indicating that an opening is open. The thermal load determining parts determine whether the thermal load in the cabin exceeds the air-conditioning capacity of the automatic control. Regardless of the inside temperature, the power saving control parts perform power saving control to prevent power consumption from increasing when the open signal is detected and it has been determined that the thermal load exceeds the air-conditioning capacity of the automatic control.
