Title:
AIR-CONDITIONING DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP3206046
Kind Code:
B2
Abstract:
PURPOSE: To provide an air-conditioning device for a vehicle in which a fluctuation in temperature in a car room owing to solar radiation can be suppressed without causing a cold feeling to a passenger.
CONSTITUTION: A blower 2 is regulated to vary an airflow of discharge air and through regulation of the openings of air dampers 8 and 9 and a damper 17 for bypass cold air, the temperature of discharge air is varied. A controller 20 calculates a target discharge temperature according to a set temperature Tset, the internal and external temperatures Tf and Tam of a vehicle, and a ratio between an amount of heat received by a passenger through a car body and an a total amount of heat received through solar radiation, and calculates a face target discharge temperature from the calculated target discharge temperature. Further, the controller calculates a face increase airflow according to a ratio between an amount of heat directly received by a passenger and a total amount of heat received through solar radiation through a heat balance formula and determines a face airflow from the face increase airflow.
