CO2在超临界区管内冷却的换热关联式

摘要

自然制冷剂CO2 的应用日益广泛, 尤其是在跨临界循环的热泵热水器中. 本文综述了超临界CO2 在管内冷却传热关联式的比较和验证.%The natural refrigerant CO2 is used widely, especially in trans -critical cycle heat pump water heat-ers. In this paper, the comparison and validation of heat transfer correlations for in-tube cooling of supercritical CO2 is discussed.
