组合式空调机组供冷量测量的不确定度评定

摘要

介绍了空调机组供冷量的测试方法.并在对某机组供冷量实测的基础上,详细分析了水侧及空气侧供冷量测量的不确定度及其主要来源.结果表明,供冷量测量不确定度的主要因素是进出风干、湿球温度和进出水温度及水流量.%Presents the test methods of cooling capacity of the air handling units. Based on the cooling capacity measurement of an actual unit, analyses the uncertainty and main sources in detail. As a result, theuncertainty of cooling capacity measurement results mainly from the dry-bulb and wet-bulb temperature of entering and leaving air, temperature of entering and leaving water and water flow rate.
