Document Type and Number:
Japanese Patent JP7294000
Kind Code:
B2
Abstract:
To provide an air conditioner for vehicle capable of suppressing deterioration of cooling efficiency of a cooling object to a minimum, while maintaining air conditioning capacity, in performing air conditioning in a cabin and cooling of the cooling object.SOLUTION: An air conditioner 1 for vehicle includes a refrigeration cycle device 10, a solenoid valve 14a for air conditioning and a solenoid valve 14b for battery, a switching control part 50a, a flow rate control part 50b for cooling, and a minimum opening determination part 50c. The refrigeration cycle device 10 includes a compressor 11, an evaporator 16 for air conditioning, an evaporator 19a for right side battery and an evaporator 19b for left side battery, and an expansion valve 18a for right side battery and an expansion valve 18b for left side battery. The minimum opening determination part 50c determines a minimum opening of the expansion valve 18a for right side battery and the expansion valve 18b for left side battery in Step S414. The minimum opening determination part 50c determines the minimum opening in an air conditioning cooling cycle at a value smaller than the minimum opening in a cooling single cycle.SELECTED DRAWING: Figure 14
