Recommended Unit Cooler Placement
Some general rules for evaporator placement which must be
followed are:
1.
The air pattern must cover the entire room.
2.
NEVER locate evaporators over doors.
3.
Location of aisles, racks, etc. must be known.
4.
Location relative to compressors for minimum pipe runs.
5.
Location of condensate drains for minimum run.
The size and shape of the storage will generally determine the
type and number of evaporators to be used and their location.
The following are some typical examples:
