Fine design and energy efficient operation of air conditioning system in

The key points of fine design and operation of the air conditioning system of the project are presented. Through annual dynamic load and technical and economic comparison, the type of cold and heat source equipment is determined to ensure that the system is energy-saving, stable and reliable. The outdoor air and exhaust air system in the restaurant private room is used to eliminate the waste heat in inner zone, and adjust the outdoor air temperature to solve the shortcomings of two pipes system. With airflow simulation and considering room characteristics and requirements, the air outlet form and position of multi-functional hall and dining room respectively are determined to ensure comfortable use. After three years of data statistics, the projects non-heating energy consumption indicators and heating energy consumption indicators both meet the constraint values, and the non-heating energy consumption indicators in 2019 and 2020 reach the guide value.
