Adaptability Analysis of New Ceiling Radiant Cooling Panels with Dedicated Outdoor Air Systems Used in Summer Moist Heat Regions

Abstract:

This paper introduces the operating principle and system components of Ceiling Radiant Cooling Panels (CRCP) with Dedicated Outdoor Air Systems (DOAS), moreover, analyses not only the advantages of CRCP/DOAS system in terms of comfort, energy conservation and healthy environmental protection, but also the three obstacles to the system when running in summer moist heat regions condensation, radiant cooling capacity and first cost. The major defect of CRCP is proposed that the surface temperature of the panel is uneven, while the shortage of DOAS is the insufficiency of outdoor air handling. A new CRCP/DOAS system is provided in this paper, including patent radiant cooling panel and patent air condition. We also expound the characteristics of this new system, and list the recommended design parameters as well.
