An air conditioner for a vehicle includes a vapor compression refrigeration cycle switchable between a heat pump cycle and a cooler cycle, a heat core configured to heat air to be blown into a vehicle compartment by using coolant of an engine of the vehicle as a heat source, and a controller configured to control operation of the vapor compression refrigeration cycle. The controller controls the vapor compression refrigeration cycle to be operated as the cooler cycle so as to perform a defrosting control of the outdoor heat exchanger, and outputs an operation request signal to the engine, when the controller determines that the outdoor heat exchanger is frosted.

An air-conditioning device for a vehicle includes a blower and an estimating portion. The blower is disposed in an air-conditioning case, and performs a dry control for a heat exchanger arranged in a passenger compartment of the vehicle by sending air. The blower uses one of power supplied from an external power source, power supplied from the battery having residual quantity equal to or larger than a predetermined quantity, or power supplied from an in-vehicle solar cell, while the vehicle is parked. The estimating portion estimates an approximate elimination of odor generated from the heat exchanger by starting the sending of air, and stops the blower based on the estimation.

In a vehicle air conditioner with an automatic control having a learning function of manual operation, when a passenger manually sets an air blowing amount in the automatic control, it is determined whether or not an air blowing amount after the manual operation is in a readily sensible area. When a change of the air amount due to the manual operation is in the readily sensible area, a reflecting degree of the manual operation reflected in an air amount control pattern is increased. For example, 100% of the manual operation is reflected in the air amount control pattern in the readily sensible area, while about tens % of manual operations is generally reflected in the air amount control pattern totally.

In a vehicle air conditioner, a first air-conditioning control value is calculated based on a surface temperature detected by a non-contact temperature sensor in a temperature detection area of a passenger compartment. When it is determined that an obstacle exists between the temperature detection area and the non-contact temperature sensor, a second air-conditioning control value is calculated according to a temperature information that is influenced less by the obstacle than the detected surface temperature. When it is determined that the obstacle does not exist, an air conditioning state of the passenger compartment is controlled based on the first air-conditioning control value. When it is determined that the obstacle exists, the first air-conditioning control value is corrected to approach the second air-conditioning control value to calculate a corrected air-conditioning control value, so that the air conditioning state can be controlled satisfactorily.

An air conditioner for a vehicle includes a vapor compression refrigeration cycle configured to have a heat pump cycle for heating air to be blown into an interior of a vehicle compartment, and a heating member for heating the air using a coolant of an internal combustion engine of the vehicle as a heat source. In the air conditioner, an operation request signal is output by an air conditioning controller to the internal combustion engine when an outside air temperature is lower than a predetermined threshold.
