Features and Benefits 20 to 120 Ton Units Trane 20 to 120 ton air-cooled condensers have an operating range of 40 F to 115 F, with a low ambient option down to 0 F. The control panel is factory-installed and wired to prevent potential damage and to provide weathertight protection. The control panel contains: • fan motor contactors. • fan cycling controls. • terminal point connection for compressor interlock. • 115-volt control power transformer.
Application Considerations Unit Location Clearance Ambient Limitations Unobstructed flow of condenser air is essential to maintaining capacity and operating efficiency. When determining unit placement, careful consideration must be given to assure a sufficient flow of air across the condenser heat transfer surface. Two detrimental conditions are possible and must be avoided: Warm air recirculation and coil starvation. Vertical condenser air discharge must be unobstructed.
Selection Procedures c Example: At 95 F ambient and 129.4 F condensing temperature there is a 10.1% increase in capacity due to subcooling. This yields a system net capacity of 93.8 tons x 110% = 103.2 tons. Determine the total cooling load and the evaporator sst and compressor required. Transfer the results from the compressor and condenser plots to Chart SP-1 and do the following. Draw a line through the two points representing gross heat compressor capacities less subcooling (105.6 and 82.3).
