摘要

从机房空调产品开发中送风风量该如何确定的问题出发，对机房空调国标GB/T19413-2003的相关要求以及市场上主流外资品牌机房空调的相关参数做了理论对比分析和实验验证.分析显示，国标要求送回风温差≤7 ℃，则在保证显热比的条件下，每千瓦全热制冷量所需要的最小循环风量为376 m

/h；而外资品牌大部分设计的送回风温差为≤11 ℃，在保证相同显热比的条件下，每千瓦全热制冷量所需要的最小循环风量为264 m

/h，风量降低29.8%，出风温度在13～15 ℃之间，机组噪声平均可以降低1.2 dBA.同时，从机房内温度控制精度和换气次数两个方面的分析也表明264 m

/h的风量设计可以满足相关要求.机房空调风量设计应在满足此最低要求的基础上，根据实际情况适当增加.

Abstract

Beginning with air volume determination in the design of precision air conditioning unit

it presents a detailed comparative analysis of the related requirements for the GB/T19413-2003 and the parameters of the mainstream foreign precision air conditioning unit. The analysis shows that the national standard specifies that the air supply temperature difference must be less than 7℃

and under the condition of sensible heat ratio air volume needed for per kW cooling capacity is at least 376 m

h while the air supply temperature difference for most foreign brands is less than 11℃

and under the condition of the same sensible heat ratio

air volume needed for per kW cooling capacity is only 264 m

with air volume reduced by 29.8%

the air outlet

temperature being between 13 ℃ and 15 ℃

and the average noise value of the product reduced by 1.2 dBA. At the same time

the analysis of the temperature control precision and ventilation rate also indicates that the air volume of 264 m

/h can satisfy the requirements. The design of air volume should meet the minimum requirements and increase properly according to the actual situation.
