About this file
These mechanical documents are for the P-475 Aircraft Maintenance Hangar Parking Garage project at MCAS Beaufort, South Carolina, developed by Naval Facilities Engineering Systems Command (NAVFAC). The drawings detail mechanical systems, specifically ductless split air conditioning units with three units (AC-1.7, AC-1.8, AC-1.9) serving different rooms: Solar Inverter (P103), Electrical (P104), and Sprinkler (P105). The units use R454B refrigerant, operate at 208V, and are designed for continuous 24/7 occupied mode with space temperature control set at 80°F in summer and 55°F in winter. The condensing units (CU-1.7, CU-1.8, CU-1.9) are located at grade level and have cooling capacities ranging from 10.8 to 12.2 MBH with EER ratings between 10.8 and 12.2.
The mechanical plans include specific installation notes such as routing refrigerant piping to avoid electrical equipment, providing exterior exposure corrosion protection, and implementing environmental severity classification C4 for building systems in specific rooms. The design conditions specify outdoor summer dry bulb temperature at 93°F, summer wet bulb at 78°F, and winter dry bulb at 32°F. The documents are part of a comprehensive set of mechanical drawings for a naval facility project, with modifications noted as P00005 in May 2023 and P00006/P00007 in October 2025.
