Title:
AIR CONDITIONER FOR ELECTRIC AUTOMOBILE AND CONTROL METHOD THEREOF
Document Type and Number:
Japanese Patent JP3028664
Kind Code:
B2
Abstract:
PURPOSE: To provide an electric automobile air conditioner which is most power saving by way of being set to an outside air inlet value where the sum total of electric power to be fed to an electric heating element and a compressor power source for defogging a window according to inside and outside air conditions and so on, becomes minimized.
CONSTITUTION: An inside and outside air selector damper 13 connected to a servomotor 12 is installed in an air inlet port of a blower unit 10 constituting an electric automobile air conditioner 100. In addition, an electric heating element 31 is interposed between two-layer structural windows 30. Moreover, output signals out of each sensor and a temperature setter for determining inside and outside air conditions are inputted into an engine control unit 20. At this engine control unit 20, an outside air inlet value, where the sum total of electric power to be fed to the electric heating element 31 and a compressor power source of the air conditioner becomes minimized, is operated, and on the basis of this operated value, opening of the inside and outside air selector damper 13 is controlled. With this constitution, in a car room can be set to the irreducible minimum of necessity.
