About this file
This document is a technical equipment specification sheet for HVAC equipment designed for the New Haven Animal Shelter renovation and addition project located in Connecticut (DOAS Job #57). The specification details a complete rooftop unit system featuring dual variable capacity scroll compressors using R-454B refrigerant with a design system charge of 220/361 ounces, rated for 3,350 SCFM airflow capacity. The unit incorporates an energy recovery wheel (ERC-5255C-4M) with total effectiveness of 64.8% in summer and 71.6% in winter, a natural gas heating system with 270 MBH consumption and 9.0:1 turndown ratio, and dual fans (24.5-inch supply fan and 22-inch exhaust fan) configured for variable frequency drive control. The equipment is specified with a single-zone VAV controller featuring AAON controls with BACnet IP/MSTP connectivity, modulating hot gas reheat, and comprehensive safety features including A2L mitigation boards for refrigerant leak detection and remote shutdown capabilities. Unit specifications include 208V/3-phase/60Hz electrical service with total full load amps of 77 and maximum overcurrent protection of 83 amps at 100 KAIC.
The equipment configuration represents a sophisticated integrated system designed to support the interior renovations and addition requirements outlined in the project scope, which includes modifications to restrooms, break rooms, cat isolation rooms, laundry, grooming, disinfection rooms, and new veterinary exam space. The unit submittal, dated March 17, 2026, was prepared by APA HVAC Technologies in Hartford, Connecticut, and specifies premium construction features including a galvanized double-wall cabinet with R-16 foam insulation, AAON gray paint exterior finish, and factory-wired 115V convenience outlets with LED service lights. Component documentation includes integrated control sensors (supply temperature, space temperature/humidity, building pressure, and outside temperature), multiple clogged filter switches for both standard and energy recovery filters, airflow proving switches, and comprehensive gas safety modules with dual gas sensors and ignition proof circuits supporting dual-stage modulating gas heat operation.
