Air conditioner minimizing differences in right and left temperatures
First Claim
1. An air conditioner for a vehicle having a passenger compartment, comprising:
- a first duct forming a first air passage for introducing air toward a first air conditioning zone in said passenger compartment;
a second duct for forming a second air passage for introducing air toward a second air conditioning zone in said passenger compartment;
first temperature adjusting means for adjusting a temperature of air in said first air passage according to a position thereof;
second temperature adjusting means for adjusting a temperature of air in said second air passage according to a position thereof, independently of said first temperature adjusting means;
temperature controlling means for controlling said first temperature adjusting means so as to set a deviation between target positions and actual positions of said first temperature adjusting means within a range from a negative predetermined value to a positive predetermined value and for controlling said second temperature adjusting means so as to set a deviation between target positions and actual positions of said second temperature adjusting means within a range from a negative predetermined value to a positive predetermined value; and
shifting means for shifting one of said target positions of said first and second temperature adjusting means in a deviated direction where an actual position of the other temperature adjusting means is deviated from said target position of the other temperature adjusting means such that a relative deviated amount in the respective temperature adjusting means becomes smaller than the range from the negative predetermined value to the positive predetermined value.

Abstract
According to the present invention, when target temperatures of air blown out toward a first and a second air conditioning zones are equal, a target opening degree of a second air mixing door is set to an actual opening degree of a first air mixing door. In this way, the second air mixing door is located at a deviated position in the range of -4-+4 (%) from the actual position of the first air mixing door. Thus, a relative positional deviation between the respective air mixing doors becomes 4 (%) even at maximum, which is approximately half as compared with a conventional value. Accordingly, temperatures of air blown out toward the first and second air conditioning zones can be substantially the same, and a comfortable temperature control independently for the right and left seats can be realized.
