Abstract

A method for calibrating a temperature sensor (6) arranged in a vapour compression system (1) is disclosed. The opening degree (9) of an expansion device (3) is alternatingly increased and decreased. Simultaneously a temperature (10) of refri gerant entering the evaporator (4) and a temperature ( 11) of refrigerant leaving the evaporator (4) are monitored. For each cycle of the opening degree (9) of the expansion device (3), a maximum temperature, T i m , of refrigerant entering the evaporator, and a min imum temperature, 2 , of refrigerant leaving the evaporator are registered. A calibration value, DT i, is calculated as DTi = C-(T2, min- T i m ) for each cycle, and a maximum calibration value, among the calculated values is selected. Finally, temperature measure ments performed by the first temperature sensor (6) are adjusted by an amount defined by ATi.
