MEASUREMENT SYSTEM OF AIR TEMPERATURE DISTRIBUTION OF SPACE AND MEASUREMENT METHOD

Japanese Patent JP2015224987

A

PROBLEM TO BE SOLVED: To provide a measurement system of an air temperature distribution of a space and a measurement method which can improve a measurement accuracy.SOLUTION: A measurement system includes: a plurality of wave elements arranged at predetermined intervals on the outer circumference of a measurement object space and emitting and receiving a sound; sonic wave transmission means for selecting one of the sonic wave elements and emitting the sonic wave at a predetermined time; sonic wave reception means for measuring the reception time of the sonic wave emitted by the sonic wave element other than the selected sonic wave element; propagation time calculation means for calculating a propagation time for each propagation path on the basis of the sonic wave emission time and the reception time at each position of the sonic wave elements; and temperature calculation means for calculating the temperature of the propagation path on the basis of the propagation time for each propagation time. The measurement object space is cylindrical, and the plurality of sonic wave elements vertically crosses a center axis of the cylindrical space and arranged on each circumference of a plurality of multiple parallelly arrayed virtual circuit 10 at a predetermined angle θ, and arranged at a position 8 rotated by the angle ω in the circumference direction of the virtual circle with respect to the sonic wave arranged on the adjacent virtual circle.
