The radiant cooling combined with attached jet air supply system is a temperature and humidity independent control system. Radiant cooling panels are used to bear the indoor sensible heat load, and the attached jet air supply is used to bear the indoor humidity load. Numerical simulation method is used to study the changes of indoor relative humidity and dehumidification efficiency of radiant cooling panels installed on ceiling and wall, as well as the advantages and disadvantages of all three systems taking into consideration the radiant cooling coupled with wall attached jet air supply with deflectors in terms of comfort. The results show that the attached jet has good adhesion to the cooling panel and will not leads to condensation; the dehumidification efficiency of wall attached jet is relatively poor; at the height of 0.1m, the thermal comfort of wall radiant cooling system is the best; at the height of 0.7m, the wall radiant cooling system with deflector is the best; in the working range of 1.1 ∼ 2.4m, the wall radiant cooling system is better than the ceiling radiant cooling system with or without deflector.
Key words: Radiant cooling / Dehumidification / PMV
