Considers that the series/parallel cycle of a double condenser coupling is suitable for the domestic conditions in China. Analyses the operation data in different working modes of a model machine developed and illustrates characteristics of the cycle. Explains the major differences between the double and triple effect LiBr chiller in design, running and control.
