Temperature monitoring of dryers

As the clothes dryers can reach operating temperatures as
high as 83 ⁰C, measurements were taken to assess their impact
on the surrounding ambient air temperature. Measurements
were taken at various points, including the glass cover of
the dryer (T1), the surrounding ambient temperature (T2),
and the dryer hot-air outlet (T3). Measurements were taken
with and without a load of clothes in the dryer. Refer to
Figures 7 to 10 for visual representations of the temperature
measurements.
