COOLING EFFECTS OF PREFERRED AIR VELOCITY IN MUGGY CONDITIONS

Preferred air velocity,vas investigated by testing a total of 241 Japa nese subjects under different air temperatures and humidities in a cli mate chamber. The work,vas done to encourage energy efficient air-cond itioning design. Increases in air temperature and relative humidity we re compensated by increases in preferred air velocity, and then the su bjects reported themselves both slightly cool and comfortable. In addi tion, differences in preferred air velocity with seasonal variation, i ndividual variation, age and sex were examined. (C) 1997 Elsevier Scie nce Ltd.
