Research on Anti Condensation of Radiant Ceiling Air Conditioning with Fresh Return Air Wall-Attached-Jet
By conducting experiments on radiation air conditioning and independent fresh air composite systems, this study investigates the effects of pure fresh air wall-attached-jet conditions and mixed fresh air wall-attached-jet con-ditions on the system attachment layer, and further investigates the anti condensation effect of mixed fresh air wall-attached-jet on radiation ceiling air conditioning systems. Comparing the air parameters of the radiation plate attachment layer under different operating conditions, it is found that the new return air mixed operating condition can increase the influence range of the wall-attached-jet and reduce the dew point temperature of the attachment layer. Compared with the pure fresh air operating condition, the maximum reduction is 2.25 ℃ . Proved the feasibility of introducing indoor return air to reduce the dew point temperature of the attached layer in radiation ceiling air conditioning.
