About this file
This document is a Carrier AquaForce Air-Cooled Chiller submittal for the Pinellas County Schools' Palm Harbor University High School project, dated January 9, 2025. The submittal details a 30XV325 model air-cooled chiller with a cooling capacity of 303 tons, featuring a VFD screw compressor, R-513A refrigerant, and manufactured in Charlotte, NC. The chiller includes multiple accessories such as isolation valves, suction line insulation, a control transformer, non-fused disconnect, sound/capacity optimization, and a permanent magnet compressor motor. The unit offers a warranty that includes parts-only coverage for the first year, with comprehensive parts and labor coverage for years 2-10.
The technical specifications reveal the chiller's comprehensive performance characteristics, including an Integrated Part Load Value (IPLV) of 20.84 BTU/Wh and a total unit power of 326.2 kW at full load. The unit operates with a minimum capacity of 16%, has two independent refrigerant circuits, and is designed with a flooded evaporator with a heater. Electrical specifications include a 460-3-60 V-Ph-Hz power configuration, with a minimum voltage of 414V and maximum of 506V. The acoustic performance is detailed, with sound power levels ranging from 83 to 99 dB depending on load percentage, and the unit is certified in accordance with AHRI Air-Cooled Water-Chilling Packages Certification Program standards.
