Development of a New Model of Single-Speed Air Conditioners at Part-Load Conditions for Hourly Simulations

International audienceA new model of HVAC systems for hourly simulations is dealt with. The latter is derived from a short time step model that is priory described. The hourly model is appraised by comparing its predictions to those of the short time step simulations. Finally, a sensitivity analysis is carried out to understand the cause of the discrepancies between the two models when it occurs. The analysis also allows to identify the factors that mainly affect the system performance
