✦ Synopsis

The double-effect vapour absorption refrigeration system working with HFC134a as refrigerant and dimethyl acetamide as absorbent is analysed. Cooling coefficients of performance in the range of 0)5-0)9 could be obtained depending on the operating conditions. However, sub-zero temperatures are difficult to obtain at typical heat source and heat rejection temperatures. Hence, cascaded systems are suggested for achieving low temperatures.
