This document is an HVAC System Diagram for a 154-Foot naval vessel (154FT) prepared by the Office of Naval Engineering at the United States Naval Shipbuilding Center. The technical drawing comprises five detailed plan sheets depicting the heating, ventilation, and air conditioning system architecture across multiple deck levels of the vessel.

The diagram details the complete HVAC system layout including equipment specifications, piping configurations, control systems, and component nomenclature. The plans illustrate supply and return air distribution networks, chilled water and hot water loops, expansion tanks, cooling units, heating elements, filters, dampers, and associated mechanical equipment positioned throughout designated compartments. Each sheet identifies specific pressure relief settings, temperature control points, duct sizing specifications, and component connections with technical annotations. The documentation includes a legend of symbols for ductwork, piping, valves, dampers, strainers, and various mechanical components. Multiple elevation views and cross-sectional details are provided to clarify three-dimensional spatial relationships and installation requirements. The revision blocks and drawing identifiers indicate this is a controlled technical document subject to engineering standards and specifications applicable to U.S. Navy vessel construction and maintenance protocols.
