Title:
AIR CONDITIONER
Document Type and Number:
Japanese Patent JP3296196
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent over-rise of idling speed in a period of small airconditioning load by controlling idling speed and a cooling fan according to the detection value of a temperature detecting means.
SOLUTION: After the start of an engine, evaporator downstream temperature T1 immediately after the start is detected by an air thermo-sensor (step 2), and whether or not an air-conditioning switch is on is judged (step 3). In case of the air-conditioning switch being on, whether or not the evaporator downstream temperature T1 immediately after the start is the specified temperature or higher is judged. In case of the temperature T1 being the specified temperature or higher, air-conditioning load is judged to be large, so as to put idling of the engine in a high rotation state and to rotate a cooling fan at high speed. In case of the temperature T1 being less than the specified temperature, idling is put in a low rotation state, and the cooling fan is rotated at low speed.
