Vehicle air conditioner and vehicle ventilation system
First Claim
1. A ventilation system for a vehicle, comprising:
- a ventilating unit which performs a ventilation of a passenger compartment using power from a battery of the vehicle while the vehicle is stopped in a vehicle state where the battery is disconnected from a driving source of the vehicle, and no passenger exists in the vehicle;
a non-contact temperature sensor which detects infrared rays radiated from a predetermined area of the passenger compartment and detects a surface temperature in the predetermined area by non-contact based on the detected infrared rays, using the power of the battery disconnected from the driving source;
ventilation determining means for determining whether the ventilation by the ventilating unit needs to be started based on the surface temperature detected by the non-contact temperature sensor using the power of the battery disconnected from the driving source; and
when the determining means determines that the ventilation by the ventilating unit needs to be started, the ventilating unit performs the ventilation using the power of the battery that is disconnected from the driving source of the vehicle.

Abstract
In a vehicle air conditioner, a non-contact temperature sensor is used as an inside air temperature sensor for detecting a temperature in a passenger compartment. Based on infrared rays radiated from a predetermined area of the passenger compartment, the non-contact temperature sensor detects a surface temperature in the predetermined area in non-contact. Therefore, it is not necessary to blow air from the passenger compartment to the inside air temperature sensor in order to detect the temperature in the passenger compartment. Thus, energy consumption can be reduced while the temperature in the passenger compartment can be accurately detected. Accordingly, while the vehicle stops, the vehicle air conditioner can accurately determine whether air conditioning control by an air conditioning unit needs be started while energy consumption can be reduced.
