When selecting a Trane chiller, you must prioritize Cooling Capacity (measured in Tons or kW) to match your facility's heat load. Key technical factors include the Compressor Type (Centrifugal, Helical Rotary/Screw, or Scroll), the Refrigerant Type (ensure compliance with environmental regulations like R-1233zd or R-514A for low GWP), and the Energy Efficiency Ratio (EER/COP). Additionally, verify the Integrated Part Load Value (IPLV) to understand performance under varying operational conditions.
