Method for defrosting an evaporator in a refrigeration circuit (2) for circulating a refrigerant in a predetermined flow direction, the refrigeration circuit (2) comprising in flow direction a compressor unit (4), a heat-rejecting heat exchanger (6), an expansion device (12) and an evaporator (14), wherein the evaporator (14) comprises at least two refrigerant conduits (42; 44) and the method comprises the following steps: (a) operating the refrigeration circuit (2) in the normal cooling mode where the refrigerant exiting the heat-rejecting heat exchanger (6) flows through the expansion device (12) and through the evaporator (14) and towards the compressor unit (4); (b) terminating the cooling mode by interrupting the flow of the refrigerant exiting the heat-rejecting heat exchanger (6) into the evaporator (14); and (c) directing hot gas refrigerant through only a portion of the refrigerant conduits (42; 44) of the evaporator (14) for defrosting the evaporator (14).
