Case Study: Impacts of Air-Conditioner Air Supply Strategy on Thermal Environment and Energy Consumption in Offices Using BES–CFD Co-Simulation

Abstract

Due to energy constraints and people’s increasing requirements for indoor thermal comfort, improving energy efficiency while ensuring thermal comfort has become the focus of research in the design and operation of HVAC systems. This study took office rooms with few people occupying them in Wuhan as the research object. The EnergyPlus-Fluent co-simulation method was used to study the impact of 12 forms of air distribution on the thermal environment and air-conditioner energy consumption. The results indicate that 3 m/s supply air velocity and 45° supply air angle are more suitable for the case model in this study. The EnergyPlus-Fluent co-simulation method used in this paper provides a reference for the study of indoor environments in offices with few people occupying them.

Study on the Impact of Building Energy Predictions Considering Weather Errors of Neighboring Weather Stations

“…Accurately predicting energy levels in future time periods not only aids building managers in optimizing energy usage and reducing operating costs but also provides decision support to mitigate adverse environmental impacts. In other domains, such as power systems, accurate load demand forecasts at different time scales (general, short-term, medium-term, and long-term) are essential for the proper operation of power facilities [ 35 , 36 , 37 ]. For instance, economic dispatch of generation capacity, fuel purchasing dispatch, security analysis, and short-term maintenance scheduling require short-term forecasts ranging from hours to weeks in advance.…”
