Cycling losses in domestic appliances: an experimental and theoretical analysis

Abstract The on/off mode is the method of control usually applied in domestic refrigeration equipment. Owing to this method of operation, cycling losses occur which depend on the on/off cycle length, the dimensions of the heat exchangers, etc. It is the aim of this study to analyse these cycling losses in detail, both numerically and experimentally. Two operation modes for cycling are selected: the condenser closed during the off-period and the condenser open during the off-period. Both cycling operation modes are compared with a continuously running system.
