Abstract
In a vehicle air conditioner, at least one of an inner surface temperature of a passenger compartment and a surface temperature of a passenger in each detection area is the passenger compartment is detected by an infrared rays sensor, and a control unit determines a solar radiation condition such as a solar radiation amount and a solar radiation direction in the passenger compartment based on the surface temperature detected by the infrared rays sensor. The control unit controls operation of an operation member such as an air mixing door, based on the determined solar radiation condition. Thus, uncomfortable feeling given to the passenger can be reduced regardless of the solar radiation condition.
Claims19
An air conditioner for a vehicle, comprising:
- an air conditioning unit for performing air conditioning of a passenger compartment of the vehicle, the air conditioning unit including an operation portion that being operated in the air conditioning;
- an environmental-condition detecting device for detecting an environmental condition of the vehicle;
- a control characteristic memory means for storing a control characteristic showing a relationship between the environmental condition detected by the environmental-condition detecting device and a control value applied to the operation portion;
- and
- a control unit for controlling operation of the operation portion based on the control characteristic stored in the control characteristic memory means, by using the environmental condition detected by the environmental-condition detecting device,
- wherein the environmental-condition detecting device includes a surface temperature detecting means for detecting at least one of an inner surface temperature of the passenger compartment and a surface temperature of a passenger, in each detection area of the passenger compartment.
An air conditioner for a vehicle, comprising:
- a temperature adjusting unit for adjusting a temperature of conditioned air to be blown into a passenger compartment of the vehicle;
- a blower for blowing conditioned air into the passenger compartment;
- an area temperature detecting device for detecting temperatures in a plurality of detection areas around a passenger in the passenger compartment, the detection areas at least include an area where the temperature is changed in accordance with a solar radiation direction;
- a target temperature calculating means for calculating a target air temperature based on at least a set temperature, an inside air temperature inside the passenger compartment, an outside air temperature outside the passenger compartment and a solar radiation amount that is calculated based on the temperature detected by the area temperature detecting device;
- and
- a control means for controlling the temperature and a flow amount of conditioned air to be blown into the passenger compartment by controlling the temperature adjusting unit and the blower in accordance with the calculated target air temperature,
- wherein the control means determines an air outlet mode in accordance with the calculated target air temperature.
