evaporator above doors

[skyboy6142]

Dear friends,

Some times I see cold rooms that evaporator has been installed above doors ! I think this place is best place that we can use for evaporator without occupying room for goods.
But I was reading a bulletin of Heatcraft factory, I saw on this "NEVER install evaporator over doors !" .

What is your opinion about this ?

Thanks.

I would suggest that it is a location that has the highest humidity due to the incoming outside air which could encourage early icing of the coil.

Always on the wall facing the door or on the side wall.
If you install it over the door, every time you open it, it sucks hot humid air with all the dirt in the air.

Bad practice.
