Some general rules for evaporator placement shall be followed:
冷风机得布置规则如下：
These Heavy Duty Evaporator ranges are standard
OEM products of Heatcraft Australia; they comprise
both ‘medium’ and ‘low’ temperature ranges. They are
intended for typical commercial sized cool room and
freezer applications for the storage of vegetables, fresh
meat, general foodstuffs, beverages, etc. They are not
intended for environments that may have harmful,
corrosive or flammable atmospheres or for the storage
of corrosive or flammable chemicals. ‘Marine’
environments are considered corrosive; please consult
Heatcraft before installing in this environment.
这些工业型冷风机是西克标准的
OEM
产品；
包括中温和低温两个应用范围。专为保存蔬
菜，鲜肉，常规食品和饮料等典型的商业冷藏
及冷冻库而设计。不能用于储藏有害，腐蚀，
易燃物的冷库，也不能用于储藏腐蚀，易燃化
学品的冷库。海洋环境是有腐蚀的；如果要安
装在这样的环境中请在安装前咨询西克。
Medium temperature range evaporators (Kirby KHDC
series) are designed at -4°C saturation suction
temperature (SST) and 6 KTD to suit room temperature
from -6°C to +20°C (refer to technical data for
maximum and minimum allowed KTD for specific SST),
for use in ‘heavy duty’ commercial cool room
applications. For rooms below 2°C, additional
defrosting means may be required. R507/R404A and
R22 are recommended refrigerants. For other
refrigerants, please refer to sales data sheet for
capacity variations.
Low temperature range evaporators (Kirby KHDF
series) are designed at -24°C SST and 6 KTD to suit
room temperatures from –4°C to –32°C (refer to
technical data for maximum and minimum allowed KTD
for specific SST), for use in ‘heavy duty’ commercial
freezer room applications. R507 or R404A are the
recommended refrigerants. For other refrigerants,
please refer to sales data sheet for capacity variations.
For lower temperatures design variations may be
required.
中温工业型冷风机 (BOHN BHDC 系列）其设
计的饱和吸气温度为
-4°C
，温差为
6K
，适用
于室温从 -6°C 到 20°C 商用冷库（特定的饱和
吸气温度下允许的最大和最小温差请参照技术
资料）。室温低于
2 °C 时需额外的除霜方
法 。 该 蒸 发 器 推 荐 使 用 的 制 冷 剂 有
R507/R404A 和 R22 。对于其他制冷剂，请参
照数据表查不同的制冷量。
低温冷风机 (BOHN BHDF 系列）其设计的饱
和吸气温度为
-24°C
，温差为
6K
，适用于室温
从 -6°C 到 -32°C 商用冷库（特殊饱和吸气温度
允许的最大和最小温差请参照技术资料）。该
蒸发器推荐使用的制冷剂有
R507/R404A
和
R22
。对于其他制冷剂，请参照数据表查的不
同的制冷量。更低的库温必须重新设计。
These standard evaporators cannot use Ammonia
(NH
3
) as refrigerant.
For special design requirements (non standard
conditions and/or refrigerants such as Glycol,
Hydrocarbons, etc), please inquire with your local
representatives and/or Heatcraft Wuxi local branches,
or call our national telephone number 0510-85282020
for your nearest available information resources
这些标准的蒸发器不能用氨
(NH
3
)
作为冷媒。
对于非标设计（非标准工况和
/
或乙二醇、碳
氢化合物等作为冷媒）请咨询西克当地代表和
/ 或西克无锡，或者拨 0510-85282020 为您

•
The air pattern shall cover the entire room or
effective area.
•
Do NOT locate evaporators over doors.
• Locate aisles, racks, etc so as not to hinder the
discharge or return airflow of the evaporator.
•
Locate relative to compressors for minimum pipe
runs.
•
Locate condensate drains for minimum pipe runs.
• 气流组织应覆盖整个房间或者有效面积。
• 禁止将蒸发器安装在门的上面。
• 过道和货架的布置不能阻碍蒸发器的送风和
回风的流道。
• 蒸发器到压缩机的管道距离尽量短。
• 排水管的走管距离尽量短。
