DEMONSTRATION OF ESP-r's ADAPTIVE CONVECTION ALGORITHM

Ian Beausoleil-Morrison

Abstract: A flow responsive algorithm was devised and imple­ mented within the ESP-r simulation program to advance the modelling of internal surface convection. The impact of this method is demonstrated with two case studies. The method is able to resolve the impact that HVAC systems have upon room convective regimes and can substantially affect simulation results. The total annual heating load predictions of an energy efficient house were found to increase by up to 3.3%. The method had an even greater impact on the simula­ tion of a typical office building conditioned with a air­ based heating and cooling system. In this case, the method increased the predicted annual heating coil load by 9% and the cooling coil load by 19%.
