Car air conditioning equipment with temperature variation system to avoid occupant boredom with constant temperature air

摘要

Car air conditioning equipment comprising: an air feeding device for feeding a constant amount of air; air-blow outlets for blowing air with an adjusted temperature into a car interior; an interior temperature detector for detecting a temperature in the car interior; a blown-air temperature detector for detecting a temperature of air blown out from the air outlet; a temperature controlling device for outputting a heating- cooling control signal to control the flow of heating-air and the flow of cooling-air which temporally varies, based on the detected interior temperature and the detected blown-air temperature; and a temperature adjusting device which includes a heating-cooling device for heating and cooling the air from the air feeding device and temporally varying the temperature of the heating-air and the cooling-air, and first mixing device for mixing the heating-air and the cooling-air from the heating- cooling device and supplying the mixed air with the adjusted temperature to the air outlet device. In a second embodiment electric heaters at the outlet vents are used to temporally vary the air temperature to avoid occupant boredom with constant temperature air.
