Claims

[Scope of utility model registration request]

(1) In a vehicle air conditioner that takes air from outside the vehicle interior into a ventilation duct, mixes hot air and cold air in the duct, and blows the mixture into the vehicle interior to control the interior temperature to a desired temperature, the temperature inside the vehicle interior is set. A temperature setting device, an outside temperature sensor that detects the outside air temperature, an inside temperature sensor that detects the inside temperature of the car, an air temperature sensor that detects the temperature of the air taken into the duct, and an amount of solar radiation that is detected. A cooling water temperature sensor that detects the engine cooling water temperature, a blower fan that is installed near the internal and external air intakes of the duct and blows air into the duct, and a vehicle that receives the detection outputs of the temperature setting device and various sensors. A control and means for calculating an air blowing amount of the blower fan that maximizes the rate of increase in indoor temperature and outputting a control signal for controlling the rotation speed of the blower fan, and a blower fan that receives the control signal. 1. A vehicle air conditioner comprising: a drive means for outputting a drive signal to the vehicle.

(2) The control means is characterized in that it calculates the air flow rate when the target blowout temperature calculated based on the detection outputs of the various sensors is higher than a reference temperature for determining the magnitude of the heating load. Scope of Claim for Utility Model Registration (1)
) The vehicle air conditioner described in item 2.

(3) The control means calculates the amount of air blown when the engine cooling water temperature is below a predetermined value when the air outlet mode of the ventilation-duct is in the heat mode, which is determined by the target air outlet temperature. Scope of request for patent registration No. (1)
The vehicle air conditioner described in paragraph 1.

(4) The control means calculates the air flow amount when the difference between the actual vehicle interior temperature and the set temperature is equal to or less than a predetermined value when the air outlet mode of the ventilation duct determined by the target air temperature is the heat mode. A vehicle air conditioner according to claim (1) of the utility model registration claim.
