Impact de la pressurisation sur la consommation d'énergie des laboratoires et des salles blanches.

Impact of pressurization on energy consumption for laboratories and clean rooms.

Résumé

Pressure differential setpoint and air tightness affect both pressure control and energy consumption for containment spaces such as laboratories and clean rooms. Due to the lack of engineering means to determine the suitable pressure differential setpoint during the design stage, such a setpoint is often intuitively selected. There is a lack of study in the literature that quantitatively examines the impacts of pressure differential setpoint and air tightness on energy consumption for containment spaces. Therefore, the objective of this study is to use simulation models to quantify the impact of pressure differential and air tightness on HVAC system energy consumption for a containment space. In this paper, three different laboratory layouts: a single laboratory, a suite of pressurized laboratories consisting of a small space within a large space, and two adjacent pressurized laboratory spaces, are modelled and simulated using MATLAB SIMULINK (Mathworks 2007).
