Title:
AIR CONDITIONER FOR VEHICLE
Document Type and Number:
Japanese Patent JPS57182509
Kind Code:
A
Abstract:

PURPOSE: To enable elimination of discomfort at the time of a differential mode by closing a lower mode damper when a room temperature deflection is larger under the differential mode and opening the same when the room temperature deflection is smaller, in a captioned air conditioner of an air mix method.

CONSTITUTION: A control program is made to store in a microcomputer beforehand, signals from a room temperature setting device and an indoor air sensor are read when a mode is turned into a differential one by pushing a defrost switch, a difference of the foregoing two signals, that is, a room temperature deflection is computed, when its computed deflection becomes larger than, for example, ±4°C mode dampers 18 and 21 are turned into closed condition respectively, then when the room temperature deflection becomes within a scope of ±4°C the lower mode damper 21 is opened as what is called a temperature adjusting area and a foot is prevented from cooling by sending a worm wind toward the foot. And when concentration of a warming function to a differential blowing out opening at the time of a differential mode is required the dampers 18 and 21 are operated under the above procedure as either of the room temperature deflections is large.
