In a hybrid vehicle air conditioning system in which coolant is supplied to a heater core from a vehicle running engine, for heating, a demand of the operation of the vehicle running engine is controlled to obtain respective set coolant temperatures TWS2 for target air-outlet temperature TAO of air sent out into a passenger compartment during a bilevel mode operation and TWS1 for the target air-outlet temperature TAO during a foot mode operation by setting the set coolant temperature TWS2 higher than the set coolant temperature TWS1.

In a battery cooling system that cools a battery by using conditioned air (inside air of a passenger compartment) of a vehicle air conditioner, a battery control unit controls a battery blower to increase an air amount supplied to the battery when a predetermined condition is satisfied. In contrast, an air-conditioning control unit decreases a compression capacity of a compression device after an air amount supplied to the battery is increased to a predetermined amount by the battery control unit. For example, the air-conditioning control unit decreases the compression capacity of the compression device after a predetermined time passes after the air amount supplied to the battery is increased to the predetermined amount. Accordingly, the temperature inside the passenger compartment and the compression device can be stably controlled.

In a vehicle air conditioner, a controller calculates a first target post-evaporator temperature for defogging a windshield based on a detection humidity of a humidity sensor, and calculates a second target post-evaporator temperature for defogging the windshield regardless of the detection humidity of the humidity sensor. Then, the controller determines a smaller one between the first and second target post-evaporator temperatures, as a target post-evaporator temperature. Accordingly, even when the humidity sensor detects a humidity lower than an actual humidity of a passenger compartment when a blower operates by a low air-blowing amount, a windshield is prevented from fogging.

In an air conditioner, a target compressor rotation speed is determined based on a target air temperature, which represents an air conditioning load, when an electric compressor is started from a stop state. Thus, an evaporator air temperature can be approximated to a target evaporator air temperature, more quickly as compared with a control method where an incremental rotation speed is added to a present rotation speed of the electric compressor, that is, 0 rpm. Accordingly, a large cooling capacity can be obtained for a short time period. Thus, an air temperature in a compartment can be quickly reduced to a comfortable temperature, when the air conditioner is started, for example.

A valve opening-closing timing control device includes a solenoid valve having a solenoid mechanism provided with a spool having an oil path groove formed in an outer face thereof, and a sleeve for housing the spool to reciprocate and slide. A wall surface of the sleeve has a first port communicating with a first hydraulic oil supply section, a second port communicating with a second hydraulic oil supply section, and a third port communicating with the side of a hydraulic oil supply source. The spool is driven and set to a first position for supplying hydraulic oil from the hydraulic oil supply source to the first port, a second position for supplying the hydraulic oil from the hydraulic oil supply source to the second port, and a third position outside an area between the first and second positions to prevent supply of hydraulic oil from the first and second ports.
