Title:
VEHICLE AIR CONDITIONING APPARATUS AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/138806
Kind Code:
A1
Abstract:
[Problem] To provide a control method for a vehicle air conditioning apparatus provided with an independent temperature adjustment function for the left and right sections, said adjustment function making it possible to prevent condensed water from freezing in an evaporator. [Solution] The downstream side of an evaporator 8 of a vehicle air conditioning apparatus is partitioned by a partitioning section 14 into a driver-side air channel 20 and a passenger-side air channel 30 other than the driver-side air channel, and a non-contact temperature sensor 50 is disposed, away from the evaporator 8, in a region facing the driver-side air channel 20. When a normal blowing mode is selected, the operating state of a compressor 10 is controlled so that detected temperatures (T8a, T8a') detected by the temperature sensor 50 fall between a lower limit (Tsd)min and an upper limit (Tsd)max of a threshold temperature (Tsd), and, when a strong blowing mode is selected, a threshold temperature (Tsp) is set at a greater value than the threshold temperature (Tsd) used when the normal blowing mode is selected.
