), and a Pt100 sensor inside. The globe thermometer temperature could be remarkably
higher than the air temperature. For example in a mountain cottage, in which air is at 0°C but the
presence of a fireplace produces an average radiation temperature of 40°C, ensuring a comfortable
condition. In normal conditions, maintaining a certain difference between average radiation
temperature and air temperature (where
T
MR
is remarkably higher than
T
A
) is preferable in order to
get a better environment quality. In houses, where fireplaces and ranges are absent, generally the
average radiation temperature is equal to the air temperature, or even lower. These conditions
(mainly in buildings with large window surfaces) are not particularly healthy as the warm humid air
facilitates the development of pathogenic organisms. From this point of view, using lamps or
radiating panels is more healthy. It is much more hygienic to use a higher average radiation
temperature than the air temperature, in order to guarantee comfort conditions. The regulations use
air temperature and not average radiation temperature to assess heating system, but this is wrong.
In order to calculate the average radiation temperature you have to connect the following
probes:
•
Globe thermometer probe
•
Air temperature measurement probe
•
Hot-wire probe for wind speed measurement
In order to measure the average radiation temperature, you should refer to the following
regulations:
•
