Abstract

This thesis presents an analysis of the cabinet loads of a typical household refrigerator/ freezer. The thennalload on the cabinet during closed door conditions is investigated. The area of greatest focus is the door and wall edge region of the refrigerator where thennal losses are greatest Conduction heat transfer into the refrigerator cabinet is quantified using numerical computer simulations and experimental measurements. The overall cabinet load is detennined, as well as specific loads for various pathways that sum to equal the total. Based on agreement between simulations and experiments, the complete edge loss accounts for approximately 30% of the overall cabinet load on the fresh food and freezer compartments. In addition to this primary finding, percentages for heat leakage directly through the door gaskets, along the steel casing at the wall and door flanges, along the steel skin in the mullion section, due to the presence of a mullion anti-sweat heater, and due to the presence of an anti-sweat condenser tube are detennined.
