Refrigerator testing

摘要

A method of predicting the power consumption of a refrigerator (10) comprises measuring the power consumption and duration of defrosting and refrigeration cycles. The measured values are used, together with an estimate of the number of defrosting cycles expected in a predetermined period, to predict the power consumption of the refrigerator (10) in a predetermined period. An apparatus for carrying out the method is also disclosed and comprises a measuring apparatus (20) operating under the control of a computer (30) which also performs the necessary calculations.
