Outdoor Air Condensers and Fluid Coolers Layout and Components
.
The general layout of AC options (air-and water-cooled) is shown on Pic.D.5 below with the outdoor air condenser
NC-B-1 (left) and fluid cooler NG-V-0 (right) as an example. While layout and main components are similar for all
applicable AC options, there are some deviations (number of fans, coil sizes, composition, etc.). Refer to AC
Options ( Basic Information chapter) for additional information.
 Cooling (AC) coil (31) (where heat from refrigerant in the outdoor condenser or glycol mixture in fluid cooler is
rejected to the ambient air) is mounted onto metal frame/air box upstream (before) the fan (32), that pulls
the air through the coil to absorb the heat.
o
Condenser/cooler piping connections (33) are identified respectively (IN – OUT, Hot gas – Liquid etc.);
 In some cases , fluid cooler piping connection(s) may be located within pump package box
(37), if fluid cooler is provided with one.

Piping connection location may vary – refer to particular cooler/condenser labels, stickers,
submittal and other documentation.
o
Depending on the type, size and installation, outdoor condensers may be provided with different set
of legs/supports (34), which are required assembly on-site – refer to the Installation manual.
o
Depending on the size and capacity, condenser or cooler may have multiple fans or coils.

Electric power is normally to be brought to disconnect (35) (if cooler/condenser is equipped with such), which
feeds it to the electrical box (36), that contains condenser or cooler power and control apparatuses.
o
Depending on type of fluid cooler, location of electrical box may slightly differ.
