Abstract: A measurement device includes a frame member rotatably supported about a first axis line, a detection body disposed inside of the frame member and rotatably supported relative to the frame member about a second axis line, and a vane disposed on one end side of the detection body in a direction orthogonal to the second axis line and that directs the other end side of the detection body in the direction orthogonal to the second axis line toward an air flow upstream side upon receiving an air flow. The measurement device includes a wind direction sensor disposed in the detection body that detects a wind direction as a direction of the other end side of the detection body in the direction orthogonal to the second axis line, and a wind speed sensor disposed in the detection body that detects a wind speed of the air flow.

Abstract: 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.

Abstract: 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.
