REFRIGERATION PLANT

Domain	Definition
Mining	A. A surface plant to form the protective barrier of frozen ground in the freezing method of shaft sinking. The cooling agent used is ammonia which, in its gaseous state, is compressed to about 120 psi (827 kPa) when it passes to the top of the condensers, emerging at the bottom as liquid ammonia under pressure. It then passes through a regulator valve into the coolers where it immediately evaporates. The latent heat of evaporation is extracted from the brine circuit--the brine being passed through the coolers by the brine pumps. The ammonia gas passes back for re-use. The brine emerges from the coolers at a temperature of -4 degrees F (-21.7 degrees C) and is pumped down the boreholes to freeze the water around the shaft sinking. b. A surface plant to cool liquids. These liquids or ice are sent underground to cool the air current in heat exchangers. By this method, the air in deep mines is cooled considerably and the working environmentis improved. See also:deep mining. (references)
