Full Description

Twelve subjects, six men and six women evaluated the effectiveness of three space heaters in producing a comfortable thermal environment during a transient warming period. The subjects voted every three minutes during a one hour exposure period in which the temperature of the occupied space was allowed to drift from 10°C to 22°C. The results showed that Heater Nos. 2 and 3 provided comfort for the subjects faster than Heater No. 1, even though all heaters had the maximum wattage of 2600 W. The results showed that the male and female subjects had similar responses and that head, hands, trunk, and back comfort were the same regardless of heater. The study represents a new methodology for evaluating the human response to the transient warming conditions developed by space heaters.
