Simplified method of air conditioning terminal model in large buildings based on EnergyPlus

Based on EnergyPlus energy consumption simulation software, studies the terminal simplification of a large air conditioning system by theoretical analysis and modeling data comparison. Studies the fan models of air conditioning terminal, and finds the relationship between fan energy consumption and air flow. Presents three simplified methods applied to different CAV and VAV systems, which can be chosen by users according to their objectives. Verifies the simplified method application to typical office buildings.
