3. Water-alcohol and water-ammonia mixtures
Dissolving low-freezing fluids, such as alcohols, in water to obtain refrigerant fluids is a technique traditionally used by refrigeration engineers. The most commonly used antifreezes are: ethylene glycol (monoethylene glycol with formula C 2 H 4 (OH) 2 ), propylene glycol (1-2 propylene glycol with formula C 3 H 6 (OH) 2 ). More anecdotal remains the use of ethanol (C 2 H 5 OH), methanol (CH 3 OH) and glycerol (C 5 H 10...
