| Application Considerations b
Provide Vertical Clearance
Vertical condenser air discharge must be unobstructed. While it is difficult to predict the degree of warm air circulation, a
unit installed as shown on the left would have its
capacity and efficiency significantly reduced. Performance data is based on free air discharge.
c
Provide Lateral Clearance
The condenser coil inlet must not be obstructed. A unit installed closer than the minimum recommended distance to a wall or
other vertical riser may experience a combination coil
starvation and warm air recirculation, resulting in unit capacity and efficiency reductions. Once again, the Adaptive Control™ microprocessor will allow
the chiller to stay on line, producing the maximum available capacity, even at less than recommended lateral clearances.
The recommended lateral clearances are depicted in the dimensional data section. These are estimates and should be
reviewed with the local Trane sales engineer at the
jobsite.
d
Provide Sufficient Unit-to-Unit Clearance
Units should be separated from each other by a sufficient distance to prevent
warm air recirculation or coil starvation. The
air-cooled Series R® chiller has the lowest recommended unit-to-unit clearance in the industry, eight
feet. Consult the local Trane sales engineer for
applications concerning close spacing and restricted
airflows.
e
Walled Enclosure Installations
When the unit is placed in an enclosure or small depression, the top of the fans should be no lower than the top of the enclosure
or depression. If they are, consideration should be
given to ducting the top of the unit. Ducting individual fans, however, is not recommended.
Such applications should always be reviewed with the
local Trane sales engineer. |
