Abstract：
This paper discusses the design of cooling tower cooling (free cooling) for VAV air conditioning systems in Shanghai area. Through the cooling load analysis of interior zone and outside air, the necessity of cooling tower cooling (free cooling) in the design of VAV air conditioning systems is pointed out. Through the analysis of cooling tower thermal performance, the feasibility of cooling tower cooling in the design of VAV air conditioning systems is proposed, and the importance of common manifold design for cooling water systems is also pointed out.
