Title:
TEMPERATURE VARYING DEVICE FOR BLOW-OUT AIR IN AIR CONDITIONER FOR VEHICLE
Document Type and Number:
Japanese Patent JPH01212615
Kind Code:
A
Abstract:
PURPOSE:To improve the comfortable feeling in the air conditioning action for a driver by allowing the driver to feel the temperature variation by intentionally varying the temperature of the air blown onto the upper half of the driver's body when the compartment temperature is close to the comfortable temperature for the driver. CONSTITUTION:The air blown from a blower 1 is temperature-adjusted through an evaporator 2, heater 3, etc., and blown into the compartment of an automobile from a number of blow-out ports 9, 12, and 15. The blower 1 and an air mixing valve 5 are controlled by a temperature controller 17 on the basis of the detection signal supplied from a compartment temperature detector 16, and the compartment temperature is kept at a set temperature. In this case, a warm air passage 18, flow rate adjusting valve 19, cold air passage 20 and a flow rate adjusting valve 21 are installed. When the difference between the detection value and set value of the compartment temperature becomes within a set range, the flow rate adjusting valves 19 and 21 are controlled by a temperature variation controller 23 so that the detection value from a blow-out air temperature detector 22 varies in a prescribed variation range through the lapse of time.
