The ranges of indoor [[temperature]], [[humidity]], and air movement, under which most persons enjoy mental and physical well-being.</div><br/> <div class="paragraph">As represented on [[comfort charts]] of the American Society of Heating and Air Conditioning Engineers, comfort zones are areas bounded by curves of [[effective temperature]] and [[relative humidity]]. The limiting conditions vary somewhat according to [[season]] and to the native [[climate]] of the person or group. In the United States the comfort zone with [[normal]] ventilation lies between air temperatures of about 17° and 24°C (63° and 75°F) at a relative humidity of 70%, and 19°C (67°F) at a relative humidity of 30%, giving an effective temperature within a few degrees of 19°C (67°F). The limits, however, vary with the season, being higher in summer than in winter. In the United Kingdom, the comfort zone is centered on an effective temperature of about 16°C (60°F). In the Tropics the comfort zone lies between the same limits of relative humidity, but at air temperatures around 26°C (78°F). <br/>''Compare'' [[comfort curve]].</div><br/> </div>
