Air conditioning system for vehicles
First Claim
1. A vehicular air conditioning system in which an air flow produced by a blower is conditioned and discharged into a passenger compartment, said system comprising:
- a regulating member for regulating an air-distribution ratio between an amount of air discharged to a right side of the passenger compartment and an amount of air discharged to a left side thereof;
a plurality of solar radiation quantity detectors for detecting quantities of solar radiation at a plurality of points in the passenger compartment;
a calculating means responsive to said solar radiation quantity detectors for calculating a direction of the solar radiation;
a first setting means for setting a rotational speed of the blower;
a second setting means responsive to the first setting means for setting a control range for the air-distribution ratio; and
a control means responsive to said calculating means for controlling the regulating member so as to obtain the air-distribution ratio suitable for the calculated direction of the solar radiation within the control range.

Abstract
In a vehicular air conditioning system, an air-distribution ratio control range is determined in accordance with a set rotational speed of a blower and the air distribution ratio is controlled in accordance with a solar radiation direction within the control range, whereby more comfortable air conditioning can be realized. The system may be arranged in such a way that the correction amount of air discharge in the case where the direction of the solar radiation is not within the a prescribed range is less than that in the case where the direction is within the perscribed range, in order to prevent unnecessarily large amount of air discharge.
