Alleviating the fouling issue of internally helical enhanced tubes within cooling system has important implications for reducing energy consumption in data centers. To address limitations experimental investigations, such as insufficient number test tubes, numerical simulations deposition characteristics 25 with different micro-rib geometric parameters are conducted employing Eulerian–Eulerian method this study. The response mechanisms and sensitivity to enhancement each single parameter on tube identified. results demonstrate that amount combined increases decrease inner diameter (Di), axial element pitch rib height ratio (p/e), increase ridges (Nsi), helix angle (αi), (ei), which is consistent change heat transfer performance surface. Meanwhile, under typical water velocity (1.6 m/s) medium potential conditions, impact overall variation asymptotic thermal resistance descending order: corresponding range (Rj) average being 2.44 × 10−5–8.01 10−5 (m2 · K)/W. In addition, a prediction model related was developed, an accuracy 4.91% predicting ratio. This work valuable understanding alleviating problem from viewpoint structural parameters.

Anti-frosting strategies of air source heat pump derived from homogenizing the uneven surface temperature of outdoor coils

Physics of Fluids, Год журнала: 2025, Номер 37(3)

Опубликована: Март 1, 2025

In actual operation of an air source heat pump unit, the outdoor coils generally showcase uneven surface temperature distribution, and this leads to frosting. Homogenizing frosting has been demonstrated be helpful for anti-frosting. study, two strategies, i.e., airflow regulation refrigerant flow regulation, were proposed tackle issue. Experimental tests with a newly designed exchanger conducted demonstrate these strategies. The experimental results depicted in semi-experimental evaluation plot, which anti-frosting potential quantitatively clarified. Specifically, by implementing critical could reduced 1.6 °C, relative humidity 4%–8%, respectively. Such optimization can significantly reduce annual accumulated duration. detail, duration decreased nearly 50% Hohhot, Urumqi, Xining; 35%–40% Beijing Lhasa, greater than 55% Kunming; 45% Wuhan 80% Shanghai. Baise, may avoided during throughout year. findings study provide some useful clues design pumps different climatic regions.
