要:为了研究制冷站氨压缩机发生泄漏时,设备摆放位直不同情况下,近地面氨气浓度始
终在
IDLH(
立即威胁生命和健康浓度)以下的最小事故排风量,同时针对制冷站机械进风口最佳
的进风高度及进风量等问题进行研究,保证站房内工作人员人身安全.采用
Fluent
数值模拟方法,
建立了制冷站氨压缩机泄漏模型,通过数据处理,给出了适用于制冷站的设备布直方式及事故排风
量.模拟结果得出:制冷站内设备应尽量布直在站房中部,机械进风机进风口下边缘高度保持在
1-
1.
5m
且不应大于
2.5
m
,为制冷站的制冷设备的安装位直、事故排风机选型及机械进风机安装
高度提供依据.

Abstract
: Based on the minimum exhaust accident research about making sure the ammonia concentration is un-
der
IDLH(immediately dangerous to life or health concentration)when the refrigeration station's ammonia compressor
is
leaking by putting the
e
伊
ipment
onto different places.
At
the same time ,
it
discussed the wind
path's
best height
and
quantity of into-wind , on the refrigeration machine ,
to
safe the staff working inside. Built up a refrigeration sta-
tion's
ammonia compressor leaking model by the
way
of Fluent numerical simulation. It tells the method of putting re-
frigeration station's equipment and the quantity of exhausting air accident
by
dealing with data information.
Th
e result
is
that the Refrigeration equipment should be put in the middle of the Station , the down-edge of the wind
path'
s into-
wind should keep within 1 to
1.
5 m and
no
more than
2.
5
m.
It
also provides evident for installing of refrigeration sta-
tion'
s machine , selecting accident exhaust fan and the height of into-wind machine' s install.
