Bob will examine refrigeration systems design and technologies available to today’s cruising boater.  The objective being to refrigerate and freeze food while reducing power consumption and required battery capacity, without generator reliance. Refrigeration typically represents the single biggest on-board daily power consumption, in many cases more than all other energy demands combined. For this reason this presentation will focus on energy management using good box design, condenser efficiencies and managing food storage temperatures. Examples of efficient box design and types of DYI construction material will be covered, as well as possible improvements that could be made to existing boxes. AC, DC, propane and engine driven condensers will be reviewed, including the latest variable speed control units. A general explanation will be given of a typical refrigeration circuit as it pertains to troubleshooting and diagnostics. This program should provide a good foundation for optimizing box design, choosing a refrigeration system and basic troubleshooting.
