The Optimization of Partial Load Operation and Energy-Saving Effect Measurement of Air Conditioning in Large Public Buildings
摘要
Abstract
The central air-conditioning system in large public buildings generally has the phenomenon of high energy consumption and long-term low load operation.Current research mostly focuses on improving the performance of individual equipment,and there is not much overall planning for the efficient operation throughout the entire life process.In terms of this phenomenon,this investigation has for the first time formed an evaluation standard based on the dynamic characteristics of the entire system-"System Operating Energy Efficiency Ratio"(SOEER),and provided a comprehensive energy-saving solution for pump air conditioning that combines mass and quantity regulation methods.Through the analysis on hotel engineering examples,it can be seen that as long as the indoor thermal environment meets the requirements of human comfort,energy utilization efficiency can be significantly improved,thereby achieving significant savings.The measurement results show that compared to the traditional constant temperature operation model,the comprehensive energy-saving operation model proposed in this paper improves the operation energy efficiency by 7.3%and reduces the energy consumption of the air-conditioning system per area by more than 12.5%under the premising of guaranteeing the indoor thermal comfort.The paper provides a referable scheme with practical guiding significance for the refined operation and energy-saving transformation of the air-conditioning systems in large public buildings.关键词
