Frequently Asked Questions
What is the efficiency difference between Trane air-cooled and water-cooled chillers?
Water-cooled Trane chillers typically achieve higher efficiency with IPLV ratings up to 0.3 kW/ton for the CenTraVac series, compared to air-cooled units that range from 0.9-1.2 kW/ton IPLV. However, water-cooled systems require cooling towers and water treatment, which affect total system efficiency and maintenance requirements.
How often should Trane chillers be serviced?
Trane recommends quarterly maintenance inspections at minimum, with more comprehensive annual service. Critical items include oil analysis, refrigerant leak checks, electrical inspections, control system verification, condenser/evaporator performance evaluation, and water quality testing for water-cooled units.
What are the advantages of Trane's Adaptive Frequency Drive technology?
Trane's Adaptive Frequency Drives (AFD) provide precise capacity control, significantly improved part-load efficiency, soft starting to reduce mechanical stress, harmonic distortion mitigation, and advanced surge protection. They can reduce annual energy consumption by 30% or more compared to fixed-speed chillers.
How long do Trane commercial chillers typically last?
With proper maintenance, Trane centrifugal chillers can last 25-30 years, while screw and scroll chillers typically last 15-20 years. Factors affecting longevity include operating hours, load profile, water quality, preventive maintenance quality, and operating environment.
