摘要
Abstract
To clarify the air conditioning system solution suitable for ultra-low energy consumption buildings in hot summer and cold winter regions,based on EnergyPlus simulation,a certain ultra-low energy consumption office building in Shanghai is taken as the research object to comparatively analyze the operational energy consumption and carbon emission characteristics of multi-split systems,centrifugal chiller+gas boiler and air-cooled heat pump systems.The results show that the energy consumption per unit air conditioning area of each system is 22.47～29.00 kWh/(m2·a),and the air conditioning system accounts for 41.0%～47.2%of the total energy consumption of the building.The total energy consumption of multi-split systems is relatively low and the indirect carbon emissions are less.The proportion of carbon emissions from refrigerant leakage will rise from 33.8%to 46.0%as the carbon factor of the power grid decreases.关键词
