前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規(guī)則》的規(guī)

定起草。

本文件代替GB/T18835—2002《谷物冷卻機》，與GB/T18835—2002相比，除結構調(diào)整和編輯性

改動外，主要技術變化如下：

a）更改了適用范圍（見第1章，2002年版的第1章）；

b）刪除了術語“空氣焓差法”及其定義（見2002年版的3.7）；

c）增加了谷物冷卻機的型式分類（見4.1）；

d）更改了谷物冷卻機的基本參數(shù)，更改了試驗工況，增加了水冷式和蒸發(fā)冷卻式的機組型式，增

加了散裝谷物冷卻機、包裝谷物冷卻機和散裝谷物糧面冷卻機的基本參數(shù)（見4.3，2002年版

的6.1.2）；

e）更改了谷物冷卻機的一般要求和零、部件要求（見5.1，2002年版的5.1和5.2）；

f）更改了試運轉(zhuǎn)的要求（見5.3，2002年版的5.3.2）；

g）更改了制冷能效比的要求和試驗方法（見5.7、6.2.6，2002年版的5.3.6、6.3.3和6.3.4）；

h）更改了單位功率送風量的要求和試驗方法（見5.8、6.2.4和6.2.6，2002年版的5.3.7、6.3.4

和6.3.5）；

i）更改了最大運行制冷的要求和試驗方法（見5.10和6.2.9，2002年版的5.3.9和6.3.6）；

j）增加了低溫制冷運行的要求和試驗方法（見5.12和6.2.10）；

k）增加了水側壓力損失的要求和試驗方法（見5.13和6.2.11）；

l）更改了噪聲的要求（見5.14，2002年版的5.3.11）；

m）更改了絕緣電阻、電氣強度、接地裝置和防觸電保護的要求和試驗方法（見5.17~5.20和

6.2.16~6.2.19，2002年版的5.1.10）；

n）刪除了淋水試驗的要求和試驗方法（見2002年版的5.1.10和6.3.11）；

o）刪除了谷物冷卻機風量及制冷量試驗方法（見2002年版的附錄A）。
