Title:
COOLING SYSTEM, AUTOMOBILE MOUNTED WITH THE SYSTEM, AND METHOD OF CONTROLLING COOLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2007/116739
Kind Code:
A1
Abstract:
In a cooling system, an indoor air suction mode and an A/C air suction mode are changed
over between each other by a damper, where the indoor air suction mode is mode where
air in an occupant compartment is sucked by driving a blower fan for a battery and
sending it to the battery and the A/C air suction mode is a mode where air cooled
by driving an air conditioner (evaporator) is sucked by the blower fan and sent
to the battery. The damper is changed over immediately when vehicle speed V is
equal to or higher than a predetermined vehicle speed Vref (S220-S240), and when
the vehicle speed V is lower than the predetermined speed, the changeover of the
damper is inhibited (S250, S260). The damper is adapted to be changed over only
when the vehicle speed V is equal to or higher than the predetermined vehicle speed
Vref, and also, when vehicle speed is high, wind noise occurring when the damper
is changed over can be masked by noise (background noise) caused by traveling.
As a result, the changeover does not cause the driver or an occupant unpleasant.
