Ceiling Radiant Cooling Panels Employing Heat-Conducting Rails: Deriving the Governing Heat Transfer Equations

摘要

The central thrust of this paper is the derivation of the governing heat transfer equations for a ceiling radiant cooling panel (CRCP) that employs an extruded aluminum heat-conducting rail (HCR) between the copper tube waterway and the ceiling to room heat transfer metal sheet. The utility of the derived governing heat transfer equations to predict the performance of CRCPs using HCRs with various geometries, materials of construction, fluid inlet temperatures and flow rates, and room environments—including mechanically induced forced convection—is also presented.
