This document is an HVAC System Diagram for a 154-foot ship prepared by the Office of Naval Engineering. The diagram consists of multiple interconnected plan views and elevations showing the heating, ventilation, and air conditioning system configuration across the vessel.

The document presents five detailed schematic pages: Plan 13-A displays the main deck HVAC equipment layout and ductwork routing; Plan 21-A illustrates the midship section with additional system components and air distribution networks; Plan 29-A depicts the engineering spaces with chiller, pump, and thermal management equipment; Elevation 39-A shows the side profile of the vessel with vertical system components; and Elevation 35-A provides the longitudinal view indicating air handling unit placement and duct runs. The diagrams include a comprehensive legend identifying over 40 different symbols representing supply ducts, return ducts, exhaust ducts, deck drains, blast gates, dampers, isolation valves, expansion tanks, pressure sensors, thermostats, chillers, compressors, strainers, and various other mechanical and control devices. Equipment nomenclature callouts reference specific components by designation number and location. The system architecture appears designed to distribute conditioned air throughout multiple compartments while managing condensation, pressure differentials, and thermal loads across the vessel's operational spaces. All drawings are scaled and include grid references for precise component location identification.
