一、前言在氟里昂水冷冷凝器中,制冷剂侧的换热强度仅为水侧的1/3,所以从50年代开始国外就推广应用低肋管,通过增加制冷剂侧的换热表面积来提高其传热性能。近些年来,由于商品市场对制冷设备的体积尺寸要求进一步减少,以便于包装、运输。产品能耗 I. Introduction In the Freon water-cooled condenser, the heat exchange between the refrigerant side and the water side is only 1/3, so from the 1950s onwards to promote the use of low-cost tubes, by increasing the refrigerant side of the heat transfer surface area to Improve its heat transfer performance. In recent years, due to the commodity market to further reduce the size requirements of refrigeration equipment, in order to facilitate packaging, transportation. Product energy consumption
