Development of a model to simulate the performance of hydronic radiant cooling ceilings.

Author(s) : STETIU C., FEUSTEL H. E., WINKELMANN F. C.

Summary

The evaluation of the theoretical performance of hydronic systems could be made most conveniently by computer models. Energy analysis programs such as DOE 2 do not have the capability to simulate hydronic radiant systems yet. The development of a model that can accurately simulate the dynamic performance of hydronic radiant cooling systems is described. The model can calculate loads, heat extraction rates, room air temperature, and room surface temperature distributions, and can be used to evaluate issues such as thermal comfort, controls, system sizing, system configuration, and dynamic response. The model was created with SPARK, developed at a national laboratory, which provides a methodology for describing and solving the dynamic, nonlinear equations that correspond to complex physical systems.
