Energy-saving Renovation and Design of Central Air Conditioning under"Dual Carbon"Goals
Under the"dual carbon"goals,with the continuous improvement of people's green and energy-saving awareness,central air conditioning systems,as important energy consumption in buildings,are receiving more and more social attention.The air conditioning water system is a key component of the central air conditioning system,of which the energy consumption status,operation strategy and energy-saving design cannot be separated from the consideration of the hydraulic characteristics of the system.From this perspective,the problems of large flow rate,small temperature difference,high resistance and hydraulic balance in the central air conditioning water system were analyzed.It was explored that how to understand the essence of supply-demand imbalance through analyzing hydraulic problems,and corresponding hydraulic formulas and analysis conclusions were derived by discussing the hydraulic characteristics of the system loop and the model of system resistance characteristics.A reference conclusion was provided for the comprehensive energy-saving design of the central air conditioning water system,which requires low system resistance,good hydraulic balance,high hydraulic adjustability and reasonable system configuration,in order to assist the energy-saving transformation and design of the central air conditioning in the field of"dual carbon"green energy conservation.
