Heatcraft Refrigeration Products Condensing Units H-IM-CU Benutzerhandbuch

The most important consideration which must be taken into account when

deciding upon the location of air-cooled equipment is the provision for a

supply of ambient air to the condenser, and removal of heated air from the

condensing unit or remote condenser area. Where this essential requirement

is not adhered to, it will result in higher head pressures, which cause poor

operation and potential failure of equipment. Units must not be located

in the vicinity of steam, hot air or fume exhausts. Corrosive atmospheres

require custom designed condensers.

Another consideration which must be taken is that the unit should be

mounted away from noise sensitive spaces and must have adequate support

to avoid vibration and noise transmission into the building. Units should be

mounted over corridors, utility areas, rest rooms and other auxiliary areas

where high levels of sound are not an important factor. Sound and structural

consultants should be retained for recommendations.

Space and Location Requirements for
Air Cooled Condensing Units and Remote Condensers

Figure 1. Space and Location Requirements for Condensing Units

Units in Pits

The top of the unit should be level with the top of the pit, and side

distance increased to “2W”.
If the top of the unit is not level with the top of pit, discharge cones or

stacks must be used to raise discharge air to the top of the pit. This is a

minimum requirement.

Decorative Fences

Fences must have 50% free area, with 1 foot undercut, a “W”

minimum clearance, and must not exceed the top of unit. If these

requirements are not met, unit must be installed as indicated for

“Units in pits”.

Walls or Obstructions

The unit should be located so that air may circulate freely and not be

recirculated. For proper air flow and access all sides of the unit should be

a minimum of “W” away from any wall or obstruction. It is preferred that

this distance be increased whenever possible. Care should be taken to

see that ample room is left for maintenance work through access doors

and panels. Overhead obstructions are not permitted. When the unit is

in an area where it is enclosed by three walls the unit must be installed

as indicated for units in a pit.

Walls or Obstructions for Horizontal Air Flow

Multiple Units with Horizontal Air Flow

* “W” = Total width of the condensing unit

Multiple Units

For units placed side by side, the minimum distance between

units is the width of the largest unit. If units are placed end to

end, the minimum distance between units is 4 feet.
