Application Considerations

b

ProvideVertical Clearance

Vertical condenser air discharge must be unobstructed.While it is difficult to predict the degree of warm air recirculation, a unit installed as shown below would have its capacity and efficiency significantly reduced — possibly to the degree of nuisance high head pressure trip outs. 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 of coil starvation and warm air recirculation, resulting in unit capacity and efficiency reductions and possible excessive head pressures.

The recommended lateral clearances are depicted in the dimensional data section. These are estimates and should be reviewed with the localTrane sales engineer at the jobsite.

d

Provide Sufficient Unit-to-Unit Clearance

Units should be separated from each other by sufficient distance to prevent warm air recirculation or coil starvation. Doubling the recommended single unit air-cooled chiller clearances will generally prove to be adequate.

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 localTrane sales engineer.

WATERTREATMENT

Dirt, scale, products of corrosion, and other foreign material in the water will adversely affect heat transfer between the water and system components.

Foreign matter in the chilled water system can also increase pressure drop and, consequently, reduce waterflow. Proper water treatment must be determined locally and depends on the type of system and local water characteristics.

Do not use salt or brackish water inTrane chillers. Use of either will lead to a shortened life.Trane encourages the employment of a reputable water treatment specialist, familiar with local water conditions, to assist in the establishment of a proper water treatment program.

The capacities given in the “Performance Data” section of this catalog are based on water with a fouling factor of 0.0001 (in accordance with ARI 550/590-98). For capacities at other fouling factors, see “Performance Adjustment Factors” section of this catalog.

EFFECT OFALTITUDE ON CAPACITY

Chiller capacities given in the “Performance Data” section are based upon application at sea level. At elevations substantially above sea level, the decreased air density will decrease condenser capacity and, therefore, unit capacity and efficiency. The adjustment factors in the “Performance Adjustment Factors” section of this catalog can be applied directly to the performance data to determine the unit’s adjusted performance.
