Abstract

The estimation of the cooling power considerably influences the electrical energy consumption. Thus, numerical methods for its definition are crucial for HVAC systems design. The present study aims at investigating the cooling power variation in a residential building using different combinations of algorithms available in the E+ library to calculate indoor/outdoor convection and energy balance. Parametric and non-parametric statistical tests were performed to evaluate significant differences between the analyzed combinations. There is at least one significant difference between the [simple- adaptive-convection] and [simple-tarp] groups. The choice of algorithm can significantly influence the definition of artificial air conditioning systems. Thus, the present work points out the weight of choosing different combinations of algorithms in estimating the cooling heat load as a way to assist the decision-making about the simulation input settings.
