SA-12-C042 -- Experimental Study on Ceiling Radiant Cooling Panel System with Personal Floor Diffuser

A ceiling radiant cooling panel (CRCP) system provides high comfort to occupants since it does not produce draught.However, some occupants might feel uncomfortable in a room equipped with CRCP system, precisely due to the lack ofdraught. To solve this problem, an HVAC system using CRCPs and personal floor diffusers is proposed. An experimentalfacility for this HVAC system is constructed, and thermal performance tests as well as thermal environment surveys areperformed. This paper presents an outline of the experimental study on the abovementioned HVAC system and shows that thesystem can efficiently remove the cooling load while maintaining comfortable indoor conditions for the occupants.
