描述了一个涉及现场取样和分析的程序，以确定冷水机组蒸发器中使用的水质。解释数据以推断蒸发器管水侧污垢阻力的可能性。指出问题涉及铜管中的管侧污垢，水流速度为5-10 ft/s，温度为42-52华氏度。进行水质测试以确定沉淀、生物、腐蚀和颗粒污染的可能性。从美国各地的71台冷水机中采集水样。每个采样点都填写了一份调查问卷。 一个统计模型被用于评估冷冻水对各种污染机制的潜在影响。在这些结论中，关键的总体发现是蒸发器管几乎没有传热表面结垢的可能性。关键词:水、质量、美国、蒸发器、冷却器、问卷调查、管道、铜、污垢、结垢、沉积物、腐蚀、颗粒引用:ASHRAE交易，第97卷，Pt。1991年，纽约

Describes a programme involving field sampling an analysis to determine the water quality used in water chiller evaporators. Interprets the data to infer the possibility for water-side fouling resistance in the evaporator tubes. States the problem involves the tube-side fouling in copper tubes with 5-10 ft/s water flow at 42-52degF. The water quality tests were conducted to determine the potential for precipitation, biological, corrosion and particulate fouling. Water samples were taken from 71 chillers across the USA. A questionnaire was filled out for each sampling site. A statistical model was applied to assess the potential of chilled water for various fouling mechanisms. Among the conclusions states that the key overall finding is that evaporator tubes have very little potential for heat transfer surface fouling.KEYWORDS: Water, quality, USA, evaporators, chillers, questionnaires, tubes, copper, fouling, scale, deposits, corrosion, particles
