Abstract (en)
A method for controlling a vapour compression system (1) is disclosed, the vapour compression system (1) comprising a compressor unit (2), a heat rejecting heat exchanger (3), an expansion device (4) and an evaporator (5) arranged in a refrigerant path. A superheat value of refrigerant leaving the evaporator (5) is derived, and a quantity being representative for a variance of the derived superheat value is calculated. A reference superheat value is calculated, based on the calculated quantity and on a minimum acceptable superheat value. The expansion device (4) is operated in accordance with the calculated reference superheat value, and in order to obtain a superheat of refrigerant leaving the evaporator (5) which is equal to the reference superheat value.
