【英文篇名】 Issues in design of the surface air cooler in fan coil units 【作者中文名】 徐凤林; 【作者英文名】 Xu Fenglin; 【作者单位】 北京空调器厂; 【文献出处】 暖通空调, HV 表冷器; 风量; 片间距; 水阻力; 【英文关键词】 fan coil unit; surface air cooler; air volume; fin pitch; resistance of watercourse; 【摘要】 认为应以湿工况风量作为对风机盘管机组的考核标准,应合理确定盘管肋片的片间距以保证表冷器的供冷量,应改进水路结构,降低水阻力。 【英文摘要】 Holds that the air volume under the wet cooling condition should be taken as an assessment criterion in stead of that when dry cooling, that the fin pitch of the coil pipe should be optimised to keep proper cooling capacity, and that the number of water passages should be doubled to reduce the resistance within the limits stipulated in the standard and to improve the heat transfer conditions.
