Properties of Refrigerant 717 (anhydrous ammonia)
by Mark Geurts
This book describes the saturation, superheat, and subcooled properties of Refrigerant 717. R-717 is a pure working fluid used in many refrigeration systems. The term anhydrous means without water. Solutions of ammonia mixed with water, called aqua-ammonia refrigerants, are often used in many absorption refrigeration systems.
