Outline
To address the issue of insufficient cooling capacity of current air‑cooled units under high‑temperature conditions in summer，a performance analysis of a 3D vertical tube parallel‑flow composite evaporative cooling condenser was conducted from the perspectives of entropy and exergy.The thermal performance of the device was simulated and calculated in conjunction with engineering application conditions，and the influence of different ambient air conditions on the cooling performance of the device was studied.The results show that when the wet‑bulb temperature varies within the range of 25~35 ℃ and other control parameters remain unchanged，the condensing pressure of the 3D vertical tube parallel‑flow composite evaporative cooling condenser increases by 7.87%.When the condensing pressure is kept constant，as the wet‑bulb temperature rises from 25 ℃ to 35 ℃，the condensing capacity decreases by 10.09%.Meanwhile，the pressure loss during the condensation process remains at a low level.The simulation results were verified and validated under the design operating point，showing good agreement with the design parameters.The influence of ambient temperature changes on this condensing device is significantly smaller than that on air‑cooled condensers，which is beneficial for improving the "peak load shifting in summer" capability of air‑cooled units.This device can be considered as a preferred auxiliary cooling device for peak shaving cooling of air‑cooled units in summer.The research provides a theoretical reference for the design optimization of evaporative cooling condensers.
