关于风机盘管机组国家标准的几点分析和探讨

Some Analyses and Discussions on National Standard for Fan-coil Unit

风机盘管机组国家标准,即GB/T19232-2003中明确规定了机组风量、供冷量试验方法的规范性附录。这些试验中所涉及的主要测量其本质即是湿空气的测量。本文主要分析了试验方法中所规定计算公式的不准确和不合理之处,并通过实测试验数据及计算结果分析了误差,提出建议使用更为合理准确的计算公式。

National standard for Fan-coil unit,namely GB/T19232-2003 has definitely regulated the normative addenda of the unit air flow rate experiment method,and cooling capacity experiment method.Main measurements in these experiments are those of humid air essentially.Inaccuracy and unreasonableness of the calculating formulas and errors in these experiment methods are analyzed through true experiment data and calculating results.Then more accurate and reasonable calculating formulas are proposed.
