Abstract
Human bodies continuously build up new thermal balance due to the changes of their activity type, emotion and thermal history, etc. A very limited number of literatures focused on metabolic rate, and far fewer among them discussed impacts of metabolic rate changes on thermal comfort in transient spaces or circumstances. By conducting a series of well-controlled laboratory experiments with an ambient temperature of 28â where subjects ride spin bicycles to simulate moderate exercise, we found: a) the recovery process of thermal comfort after moderate exercise was longer than that of heart rate or metabolic rate; b) personal-controlled desk fan had a positive effect on shortening the recovery process after exercise; c) a 'sensation bounce' phenomenon was observed from several subjects; d) the work concentration increased after moderate level of exercise with fan cooling. © 2020 16th Conference of the International Society of Indoor Air Quality and Climate: Creative and Smart Solutions for Better Built Environments, Indoor Air 2020.
