摘要
Abstract
The energy consumption of centralized cooling and heating sources accounts for a large proportion of the HVAC system,and there are many types of equipment,which makes it difficult to optimize the overall energy saving of the system,whatsmore,it lacks the support of equipment-level energy-saving algorithms.For cold and heat source hosts with high energy consumption,in response to the current situation of multiple parameters,high complexity,and difficulty in accurate modeling in its energy efficiency model algorithms,an equipment level energy-saving algorithm is proposed based on parameters such as load side water temperature,source side water temperature,source side temperature difference,and partial load rate,based on the study of the impact of operating parameters of cold and heat source hosts on energy efficiency.This algorithm adopts a decoupling algorithm with boundary constraints for water temperature conditions;Adopting dynamic programming load optimization allocation algorithm in system load distribution.After actual project verification,the average monthly electricity consumption savings rate of the system can reach 23.34%,with significant energy-saving effects.关键词
