Collana: CA - 62 - Fisciano 2007

Note:
The present study investigates the type of temperatur sensor that best represents the operative temperature, i.e., the type of sensor that will integrate the influence of air and mean radiant temperature in the same way as a person. Size, shape and colour of the sensor will have an impact on the relative influence of air and mean radiant temperature in a space.
In an experimental chamber different combinations of air temperaure and radiant heated or cooled surfaces were tested. Severaltypes of sensor (flat, Sphere, ellipsoid, half-sphere, grey, black, white) were used to measure the operative temperature. Besides comparing the type of sensor, the influence of the sensor position in the room was experimentally investigated. The results show that a grey sensor of 3-5 cm diameter is the best size. The best shape, hovewer, depends on the position of the sensor in the space.
