Outline
To address insufficient performance and excessive energy consumption in hybrid closed‑circuit cooling towers under variable operating conditions，on the basis of the prototype mixed flow closed cooling tower，it has been improved using the improved tower as the test subject，To study the effects of variations in inlet water temperature（36.9~39.9°C），circulating water flow rate （125~170 m³/h），and fan power （10.48~16 kW） on cooling capacity and energy consumption ratio.The study revealed that increasing inlet water temperature raised the circulating water temperature drop （0.8°C per 10°C increase），while cooling efficiency and cooling capacity exhibited a non‑linear initial‑increase‑followed‑by‑decrease pattern，reaching a synergistic optimization peak at 38.2°C（107.8% cooling capacity，59.7% cooling efficiency，0.146 energy consumption ratio）.Higher circulating water flow rates reduced heat transfer efficiency（12% decrease in temperature drop）but improved cooling capacity by 34.5% （89%→119.7%），concurrently lowering the energy consumption ratio by 14.9%（0.174→0.148）.Elevating fan power enhanced heat dissipation（11.4% temperature drop increase）cooling capacity improved slightly（99.5%→102%），while the energy consumption ratio increased by 25.4%（0.126→0.158）.Through multi‑parameter analysis，the research elucidates the operational mechanisms of these variables on cooling tower performance，establishes quantitative relationships between operating parameters and energy consumption metrics，and provides quantifiable optimization strategies for industrial cooling tower regulation.
