About this file
This is a set of mechanical design and construction drawings for the replacement of two rooftop ventilation units (RVU-7 and RVU-8) at New Kent High School in New Kent, Virginia. The project, identified as 25-044, involves the complete removal of existing HVAC equipment and installation of new 100% outdoor air water source heat pump units with energy recovery capabilities. The scope of work includes demolition of existing rooftop ventilation units, ductwork, piping, and condensate systems; installation of new OFCI rooftop ventilation units mounted on vibration isolation rails; new ductwork connections and transitions; new condenser water piping with heat trace protection; and new condensate piping and supports. The project is designed in accordance with the 2021 Virginia Uniform Statewide Building Code and includes detailed specifications for mechanical, electrical, and control system integration. The drawings indicate contractor responsibilities for site investigation, equipment coordination, vibration isolation installation, and compliance with school premises code of conduct. The design indicates both units will operate as constant volume systems with modulating compressors, enthalpy wheels for energy recovery, and integrated Building Automation System controls.
The design documents specify comprehensive mechanical system requirements including condenser water circulation pumps, heat trace cable installation for freeze protection, and automatic temperature controls with BAS integration currently managed by Johnson Controls. The new RVU-7 unit is sized at 5,000 CFM with dual refrigeration circuits utilizing R454B refrigerant, while RVU-8 is rated at 6,000 CFM. Both units include MERV-13 filters, hot gas reheat coils with fully modulating control, emergency electric preheat capabilities, and factory-mounted VFDs on supply and exhaust fans. Electrical requirements include single-point connections with GFCI receptacles and 277-volt field power connections managed by Division 26 contractors. The design emphasizes weathertight construction, proper clearances per electrical code, and coordination among all trades to ensure a neat and attractive installation. Pump selection details specify Grundfos inline units with variable frequency drives and premium efficiency inverter duty motors. Heat trace systems are specified for all condenser water piping above the roof line with terminal controllers providing ground fault protection and BAS monitoring capabilities.
