Comfort chart

From Glossary of Meteorology



comfort chart

As used by the American Society of Heating and Air Conditioning Engineers, a diagram showing curves of relative humidity and effective temperature superimposed upon rectangular coordinates of wet-bulb temperature and dry-bulb temperature. Upon this chart (one for each chosen rate of air movement) may be indicated comfort zones bounded by relative humidity and effective temperature curves; these zones may be determined for various conditions (different seasons, different nations, different races, different clothing, etc.).
