AN EXPERIMENTAL-STUDY ON THE EFFECT OF HUMIDITY ON THERMAL SENSATIONSOF PEOPLE IN SUMMER

1. The authors propose humidity reduction instead of lowering room tem perature in order to reduce cooling syndrome. 2. They conducted experi ments with subjects in the rooms, one with controlling humidity to abo ut 40% r.h. and another without humidity control. Air-conditioning sys tem with humidity control has a greater promise in making a comfortabl e environment, even at the temperature as high as 30 degrees C, in com parison with conventional means using temperature control alone. 3. Re lationship of actual mean votes on temperature sensation and comfort s ensation with PMV and SET, respectively, suggests that Japanese peopl e might be more sensitive to humidity than Westerners and so different methods from those used in the western countries should be required f or human thermal environmental studies with respect to the hot humid s ummer in Japan.
