Experimental and numerical study on air flow and moisture transport in sleeping environments with a task/ambient air conditioning (TAC) system

An experimental and numerical study on indoor air flow and moisture transport was performed in a bedroom with a task/ambient air conditioning (TAC) system. To better evaluate the characteristics of the TAC system, a traditional full volume (FAC) air conditioning system was also investigated. In the experimental study, the horizontal stratification of temperature distribution created by the air conditioning (A/C) system and the skin (surface) temperature of thermal manikin were reported, and the results suggested an acceptable thermal stratification and a higher nonuniformity of skin temperatures at the TAC system. In the numerical study, the air temperature and velocity fields demonstrated the effect of supply air and buoyancy driven flow inside the bedroom, and the removal of moisture near the thermal manikin.
