水平微肋管内冷凝换热特性实验关联式的研究进展

RESEARCH PROGRESS ON CONDENSATION HEAT TRANSFER CORRELATIONS FOR MICRO-FIN TUBES

概述目前国内、外空调制冷行业中普遍采用的水平微肋管内冷凝换热特性的实验关联式及其影响因素,指出正确地选用实验关联式,为空调制冷行业中冷凝器的优化设计及其制造提供可靠的依据。

The condensation heat transfer correlations for micro-fin tubes widely used in the commercial air-conditioning industry are reviewed in this paper. These heat transfer correlations were developed by using different approaches to account for the heat transfer enhancement effect in micro-fin tubes. It is indicated that positive use of these heat transfer correlations will be reliable foundation of the condenser＇s optimal design and manufacture in the commercial airconditioning industry.
