About this file
This document is a set of construction drawings for the replacement of an HVAC system at the Ohi'a Wing of Hawaii Volcanoes National Park. The project involves removing existing chiller equipment and installing a new Variable Refrigerant Flow (VRF) ductless split-system air conditioning solution. The mechanical system consists of two air-cooled condensing units (ACCU-1 rated at 36,000 BTU/hr and ACCU-2 rated at 48,000 BTU/hr) serving six wall-mounted fan coil units (FCUs) distributed across first and second floors with capacities ranging from 9,000 to 18,000 BTU/hr. All equipment is specified as Mitsubishi models with smart touch-screen controllers, and the system includes condensate drain pumps for first-floor units. Refrigerant piping uses R-454B refrigerant with specified liquid and suction line sizes, and the ACCU-1 system operates 24 hours daily while ACCU-2 operates 12 hours daily, both with a room temperature setpoint of 72°F (adjustable).
The drawings detail site plans, first and second floor layouts, mechanical demolition plans showing removal of the existing chiller yard equipment and associated piping, and electrical plans for system connections. Construction notes specify compliance with the International Code Council suite of codes effective January 1, 2024, and NFPA 70 (National Electric Code). Key requirements include contractor responsibility for site inspection prior to bidding, coordination with the contracting officer regarding field conditions and equipment clearances, proper fire-stopping of all penetrations through fire-rated assemblies, and coordination of all electrical characteristics with the electrical contractor. The contractor must provide shop drawings for equipment layout and piping coordination, repair any construction damage, and patch and paint all exposed and disturbed work to match existing surfaces.
