Abstract
A method for terminating defrosting of an evaporator () is disclosed. The evaporator () is part of a vapour compression system (). The vapour compression system () further comprises a compressor unit (), a heat rejecting heat exchanger (), and an expansion device (). The compressor unit (), the heat rejecting heat exchanger (), the expansion device () and the evaporator () are arranged in a refrigerant path, and an air flow is flowing across the evaporator (). When ice is accumulated on the evaporator (), the vapour compression system () operates in a defrosting mode. At least two temperature sensors () monitor an evaporator inlet temperature, T, at a hot gas inlet () of the evaporator () and an evaporator outlet temperature, T, at a hot gas outlet () of the evaporator (). A difference between Tand T, is monitored and defrosting is terminated when the rate of change of the difference between Tand Tapproaches zero.
