About this file
This document is a comprehensive Carrier submittal for the Pinellas County Schools Chiller Replacement project at Palm Harbor University High School, dated January 9, 2025. The submittal details two identical water-cooled chillers (CH-1 and CH-2) with model number 23XRV4040NRVAA50, each featuring 500-ton cooling capacity, Unit Mounted VFD with Harmonic Mitigation, and R-513A refrigerant. The chillers are designed with specific configurations including Nozzle-in-Head waterboxes, two passes, copper rifled tubes, and fresh water fluid type, with total rigging weight of 19,525 lbs and total operating weight of 21,755 lbs per unit.
The technical specifications demonstrate high efficiency performance, with chillers complying with multiple ASHRAE 90.1 efficiency standards from 2007 to 2016 and potential to earn one LEED EAC4 point. Each chiller operates at 460V-3-60Hz, includes automatic hot gas bypass, isolation valves, and features a control center with removable lifting lugs. The acoustic data indicates sound pressure levels ranging from 78-88 dBA depending on load percentage, and the units are manufactured in the USA (Charlotte). The submittal includes detailed performance reports, configuration details, and technical drawings showing dimensional specifications, heat exchanger configurations, and mechanical layout, providing comprehensive technical documentation for the proposed chiller replacement project.

Estimated Sound Pressure Levels - dB re: 20 micropascal.
Sound pressure levels used to develop this program were measured per AHRI Standard 575.
The sound pressure levels were measured in an acoustical free-field, i.e. a non-reflective environment. Field sound measurements can vary significantly as a function of the reflectivity and proximity of nearby surfaces and the presence of other sound sources.
