cold storage plants are large warehouses equipped with a vapour compression system for refrigeration, traditionally using ammonia as the refrigerant. The system functions through a network consisting of a compressor, condenser, expansion valve and an evaporator (referred to as bunker coils when placed in a bunker). A brief description of the refrigeration process is outlined in the next few paragraphs. The compressor sucks in saturated and dry ammonia vapour at design evaporating temperature and pressure and compresses the vapour into a pre-determined higher pressure, called the condensing pressure, with corresponding temperature. The actual temperature at the condensing pressure is considerably higher due to superheating it the compression process.
