Study on the Energy Consumption of Different Air-Conditioning Systems, Layouts and Working Hours

Abstract

This study aims to investigate different types of air conditioning systems, considering different layouts and schedules. The research analyzes chiller systems with water and air condensation with fancoils and fancoletes, VRF (Variable Refrigerant Flow) and mini splits, in two types of layouts, open office and cellular, with two-time regimes, flexible (7 a.m. to 9 p.m.) and fixed (8 a.m. to 5 p.m.). The study was applied to a 5-storey building with 500 m² per floor, located in a hot bioclimatic zone. The focus was to identify the most efficient configuration in terms of energy consumption, considering the variables of artificial conditioning system, layouts and occupancy. The research suggests that choosing the ideal air conditioning system can provide greater environmental comfort and energy efficiency.
