Abstract:

Accurate energy measurement and optimization are critical in District Cooling Systems (DCS) for achieving energy efficiency and operational reliability. This study proposes an innovative approach to enhancing BTU measurement accuracy by integrating advanced measurement and control systems into existing DCS infrastructure in smart cities. A secondary flowmeter is installed parallel to the primary system, and regression analysis is employed to model flow as a dependent variable, influenced by factors such as Pressure-Independent Balancing Control Valves (PIBCVs) and supply-return temperature differentials. Experimental results demonstrate significant improvements in flow measurement accuracy, which directly enhances BTU calculation precision. The findings contribute to optimizing DCS operations and achieving sustainable energy goals.
