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 refrigerant 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 1, max , of refrigerant entering the evaporator, and a minimum temperature, T 2,min , of refrigerant leaving the evaporator are registered. A calibration value, ΔΤ 1 , is calculated as ΔΤ 1 = C-(T 2, min - T 1, max ) for each cycle, and a maximum calibration value, among the calculated values is selected. Finally, temperature measurements performed by the first temperature sensor (6) are adjusted by an amount defined by ΔT 1, max .

For each cycle of the opening degree of the expansion device, a maximum temperature, T1, max, of refrigerant entering the evaporator, and a minimum temperature, T2, min, of refrigerant leaving the evaporator are registered. A calibration value, ΔT1, is calculated as ΔT1=C−(T2, min−T1, max) for each cycle, and a maximum calibration value, among the calculated values is selected. Finally, temperature measurements performed by the first temperature sensor are adjusted by an amount defined by ΔT1, max.
