Abstract
A method for calibrating a temperature sensor arranged in a vapor compression system is disclosed. The opening degree of an expansion device is alternatingly increased and decreased. Simultaneously a temperature of refrigerant entering the evaporator and a temperature of refrigerant leaving the evaporator are monitored. For each cycle of the opening degree of the expansion device, a maximum temperature, T, of refrigerant entering the evaporator, and a minimum temperature, T, of refrigerant leaving the evaporator are registered. A calibration value, ΔT, is calculated as ΔT=C−(T−T) 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 ΔT.
