The development of the bed-based task/ambient air conditioning system applied to sleeping environments

Abstract

Task/ambient air conditioning (TAC) system is an excellent air conditioning method due to good performance in thermal comfort, indoor air quality and energy saving. For a sleeping environment, since a sleeper is usually immobile and occupied a small space, TAC systems can be regarded as the best air conditioning method. Nowadays, some bed-based TAC systems have been proposed and its operation performances on energy use, thermal comfort and indoor air quality were experimentally and numerically studied. In this study, the previous studies on these bed-based TAC systems are reviewed and its advantages and disadvantages are summarized.
