PROBLEM TO BE SOLVED: To improve fuel consumption by reducing actuating opportunity of a fan for cooling a condenser of an air-conditioner.SOLUTION: That the speed of a running vehicle is high suggests that travel air only could cool a condenser naturally. Furthermore, that a length T of the time during which a compressor operates continuously is a specified length or less means that heat release of a coolant in the condenser is done very smoothly and heat received by the coolant at an evaporator from the air inside a cabin is small. Under this kind of condition, it is not necessary to rotate a condenser fan. Therefore, it is determined naturally not to rotate the condenser fan. |
