Ammonia has been used in refrigerating technology for nearly 130 years, making it the only refrigerant to be permanently on the market since it was first used. It is typically used in large-scale refrigerating plants on account of its excellent refrigeration effect and its specific evaporation heat value of 1,262 kJ/kg at 0℃ - second only to water.
