Scheme design and energy-saving effect evaluation of recirculated air from air conditioning system utilization in glass fiber drawing department
Through the energy-saving renovation project of a large glass fiber produc-tion enterprise in Jiaxing-Scheme design and energy-saving effect evaluation of recirculated air from air conditioning system utilization in glass fiber drawing department,The results indicated that when using the air-conditioning return air system to operate from June to September,the four-month energy-saving rates were 24.3%,29.96%,29.56%and 17.40%respectively.Combined with the average energy efficiency ratio and electricity rate standard of the chiller in summer cooling conditions used in the production line of the en-terprise,according to the calculation,the four-month net income of using the air-condi-tioning return air utilization system from June to September is about 1.25 million yuan.The equipment investment of this project is about 1.8 million yuan,and the invest-ment cost is expected to be recovered in one and a half years.
