3.2 General rules for positioning unit cooler
In order to reach the best performance of your unit
cooler，you must install unit cooler in a suitable place.
The following general rules must be followed while
selecting place for unit cooler:
1.
The distance between suction side and the wall must
be greater than a diameter of fan (229mm).
will provide uniform air distribution on suction side.
If unit cooler is placed too close to the wall, it will
form a still place in the upper part between wall and
unit cooler. This will reduce capacity of unit cooler.
2.
The suction side must be away from door. Have to
avoid the outdoor air being sucked directly into the
unit cooler while door opened, otherwise it will
accumulate heavy condensate on coil surface. Thus
will block air flow tunnel of unit cooler.
3.
Make sure there is no obstacle in front of fan(s).
Must reserve space to build up better air circulation.
If air flow is blocked, it could lead to a short circuit
at air side that will reduce the system capacity.
Adjust air blades to achieve best flow pattern.
4.
When install multi-unit coolers system, do avoid the
air flow interference between unit coolers.
Before installation, check the position with designer
or customer to find the most suitable place for the unit
cooler.
At least one fan diameter
away from wall and the space
for connecting electric wires
to terminal box!
至少與牆要有一個風車葉徑的
距離或預留接線空間！
3.2 安置蒸發器的通則
為了確保蒸發器能發揮最大的效能，必須要將蒸
發器裝置在正確的位置。在選擇安裝位置時，必須要
遵守以下的通則：
1. 蒸發器吸氣面與牆之間的距離至少必須要大於該
This
蒸發器的風車葉徑 （229mm） ，並預留連接電線到
接線盒的作業空間。這樣才能確保蒸發器迎風面
有均勻的氣流。如果蒸發器離牆太近，在牆與蒸
發器的上方空間會形成一個氣流停滯區，將造成
蒸發器的效能下降。
2. 吸氣面應遠離門，必須避免門開啟時外界溫暖的
空氣直接被蒸發器吸入，否則將造成盤管面累積
過多凝結水，造成氣流通道阻塞。
3. 確保蒸發器在使用時風車的前方無任何障礙物，
並確保有足夠的預留空間形成良好的氣流循環。
如果蒸發器的出風處被阻擋，氣流很可能形成短
循環，降低整體系統效能。利用可調式導風板獲
得最佳的氣流分配。
4. 在使用多組蒸發器系統時，要注意要避免蒸發器
之間的氣流互相干擾，造成系統效能無法如預期
設計。
在安裝前務必與系統設計者和使用者確認位置，
以獲得蒸發器的最佳安裝位置。
Suction side must be away
from door to avoid warm air
directly flows into unit cooler
while open the door.
蒸 發 器 吸 氣 端 應 遠 離 開 門
處，避免溫暖外氣直接進入
蒸發器。
