摘要: Abstract Radiant cooling ceiling systems have already been proven to potentially provide an improved thermal comfort environment. This work conducted a full-scale experiment in office, and computational fluid dynamics (CFD) simulation study for radiant system integrated with air dehumidification equipment installed this test space. The obtained results from the were compared values CFD validate accuracy of model. Predicted mean vote (PMV) index was used assess original indoor condition conditions according results. Experimental variables included supply temperature diffuser, surface temperature, area panels. In addition, diffuser position mechanical ventilation analyzed that provided suggestions on improving design proposed solutions alongside limitations energy efficiency using subtropical regions Taiwan.
