Experimental Study of the effects of Throttle valve on Auto-cascade Refrigeration System [PDF]
Proceedings of the 3rd International Conference on Material, Mechanical and Manufacturing Engineering, 2015 The objection of this article is to optimize auto-cascade refrigeration system. This refrigeration system use multiple mixture (R22/R23/R14) as the refrigerant, which is driven by the single-stage compressor. Throttle is an important composition of auto-cascade refrigerant system, which impact on evaporation temperature and refrigeration efficiency ...

Study of Water-cooled Auto-cascade Refrigeration Cycle with a Low Temperature of﹣60 ℃
Zhileng xuebao, 2015 A new water-cooled auto-cascade refrigeration cycle(WACR) using a binary refrigerant mixture is presented, which adopts a condenser-phase separator instead of a condenser and an evaporative separator in traditional auto-cascade refrigeration cycle.

That sinkin’ feeling: Environmentally induced distress on a disappearing island
Medical Anthropology Quarterly, EarlyView.Abstract Residents of Tangier Island, Virginia, a subsiding island in the Chesapeake Bay, embody psychosocial dimensions of environmental change. Analysis of ethnographic data shows islanders’ experiences and articulations of anxiety, panic, and despair as “that sinkin’ feeling,” resulting from the stress of living with the long‐term threat of imminent
