Air Movement Acceptibility
Another factor investigated during our qualitative testing was the acceptability of the air movement. This was measured in a similar manner to thermal sensation, and the collated responses are shown below.
For ease of comparison the responses were averaged using the same method as the thermal sensation responses shown here, and the results are shown below.
The most obvious characteristic identified here is that the participants strongly prefer having a higher air speed. If it had been possible to increase the air speed above the current maximum, a significant proportion of the participants would have done so, and only two responses requested a decrease in air speed.
On the other hand, looking into these results in slightly more detail reveals another interesting feature. Tabulating the data it becomes very easy to compare responses between participants, shown in the table below.
It would appear that the participants who desired more air are doing it in order to feel cooler. Those who didn't desire a temperature change also didn't desire an air speed change. The thermal sensation and the air speed are therefore closely linked, and in reality it is not really possible to consider one without the other.
