Selection analysis and design of free cooling system in a Beijing commercial inner area
With the implementation of the national"dual carbon"policy,the construction of energy-saving,low-carbon,green ecology,intensive and efficient building energy system,has important practical significance and far-reaching strategic significance.based on a large-scale commercial complex project in Tongzhou,Beijing,.For the inner area with large depth and large waste heat,in winter or the transition season with low outdoor temperature,analyzes the selection basis of free refrigeration system,from the two aspects of making full use of outdoor fresh air and cooling tower cooling.Under the premise of not increasing heat consumption,appropriately increasing the fresh air volume and solving the problem of low-temperature air supply.Priority use of fresh air system for some stores in the commercial inner area;For the stores that still cannot elimination of waste heat in the inner area by using the free cooling of fresh air,the free cooling of cooling toweris adopted.Describes the design approach for free cooling of cooling tower:main parameter selection,equipment configuration and system design calculation process,propose the self-control points that need attention and are easy to overlook in system design.Provide reference for the selection and design of free refrigeration systems of similar projects.
