HVAC system enhancement

A project submitted to the faculty of the California Maritime Academy in partial fulfillment of the requirements for the degree of Bachelors of Science in Mechanical Engineering.

The Golden Bear's original HVAC system was designed to cool equipment intended for sonar mapping. This equipment gave off high sensible heat loads; therefore cooling loads were designed accordingly. Although now repurposed as a training ship for cadets, the existing HVAC system currently operates in the manner in which it was originally designed. Enormous amounts of energy are still used to operate this system despite the absence of sonar equipment providing a high heat load. The goal of our project is to design a new heating, ventilating, and air conditioning (HVAC) system for the Training Ship Golden Bear that reflects the way the ship operates today. Objectives for our project include site surveys to determine which areas of the ship are under or over served by the HVAC system, analyses of the HVAC, chilled water, and diesel generator systems to identify inefficiencies, and inquiring with Chief Engineers Coyle and Davidson about a new variable frequency drive chiller. Our project goal is to present professional plans for a system that meets the current needs of the ship more completely and efficiently than the existing one. We hope that this system will pay for itself in the form of reduced fuel costs, and that these savings can be passed on to future students.
