compression the basic components of any refrigeration system (figure ) working on the vapour compression cycle, are the compressor, condenser, expansion valve, evaporator and the refrigerant fluid which is alternately vaporized and liquefied during the refrigeration cycle. the temperature at which a...
which is condensed by cooling to about k in steel-lined condensers, and then removed and cast into ingots: the forward reaction is endothermic and the position of equilibrium is in favour of magnesium oxide. however, by removing the magnesium vapour as it is produced, the reactiongoes to completion....
