PROBLEM TO BE SOLVED: To calculate Wet-Bulb Globe Temperature by automatically selecting a calculation expression.SOLUTION: A Wet-Bulb Globe Temperature measuring device 10 includes a globe temperature sensor 12, an atmosphere temperature sensor 14, a humidity sensor 15 and a control unit 16. The globe temperature sensor 12 detects globe temperature. The atmosphere temperature sensor 14 detects atmosphere temperature. The control unit 16 compares a threshold with a difference between the globe temperature detected by the globe temperature sensor 12 and the atmosphere temperature detected by the atmosphere temperature sensor. When the difference is higher than the threshold, the control unit 16 uses a calculation expression for outdoor Web-Bulb Globe Temperature to calculate Wet-Bulb Globe Temperature. When the difference is lower than the threshold, the control unit 16 uses a calculation expression for indoor Wet-Bulb Globe Temperature to calculate the Wet-Bulb Globe Temperature. |
