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.

Car air conditioning equipment with temperature variation system to

The temperature and velocity of a wind blown from an air-conditioner are controlled in such a manner that a temperature sensation value TS expressed by the following formula becomes a targeted temperature sensation value by using facial skin temperature t.sub.SK and a rate of change in the facial skin temperature, t'.sub.SK : TS=A(t.sub.SK -B)+Ct'.sub.SK, where A is a coefficient in the range of 0.4-1.0; B is a coefficient in the range of 32.8-35.0; and C is a coefficient in the range of 10.0-85.0.

Control apparatus for air-conditioner

A control apparatus for an air-conditioner provided with a flow controlling means which controls the amount of air blown into a room, a temperature control means to which controls the temperature of air blown, a skin temperature detecting means which detects the actual skin temperature of persons in the room, a temperature sensation determining means which determines the actual temperature sensation of persons in the room in accordance with the skin temperature detected above and the rate of change of this detected skin temperature, and an electrical control means which makes the flow control means bring the temperature sensation determined above into line with the target temperature sensation and which makes the temperature control means perform temperature control.
