Energy analysis of two-phase secondary refrigeration in steady-state operation, part 2: Exergy analysis and effects of phase change kinetics

Abstract : The NWT Ice Patch Study was developed in partnership with the Shúhtagot’ine residents of Tulita, Northwest Territories, Canada. This paper explores how Shúhtagot’ine traditional knowledge, collected through the direct participation of Elders in our archaeological fieldwork, science camps with Elders and youth, Elder interviews, and traditional land-use mapping, is informing our interpretation of archaeological data collected at alpine ice patches in the Selwyn Mountains. While knowledge of bowand - arrow and snare technologies persists in Shúhtagot’ine culture, Shúhtagot’ine oral history does not contain detailed knowledge of throwing dart technology. Using data collected in our traditional land - use mapping project, we consider the role of ice patches in the broader context of Shúhtagot’ine land use. We propose that resource harvesting on high alpine plateaus and adjacent ice patches in the summer was more important in late precontact times than it was after contact. Shúhtagot’ine land-use practices involve long-distance travel in all seasons. Safe travel in the alpine landscape requires detailed knowledge of environmental conditions, such as snow and ice conditions, and respectful engagement with the spiritual entities inhabiting the landscape
