Abstract: A method for controlling a vapour compression system (1) comprising an ejector (6) is disclosed. In the case that a pressure difference between a pressure prevailing in the receiver (7) and a pressure of refrigerant leaving the evaporator (9) decreases below a first lower threshold value, the pressure of refrigerant leaving the heat rejecting heat exchanger (5) is kept at a level which is slightly higher than the pressure level providing optimal COP. Thereby the ejector (6) can operate at lower ambient temperatures, and the energy efficiency of the vapour compression system (1) is improved.

Abstract: A method for estimating a thermal capacity of foodstuff stored in a refrigerated volume of a refrigeration system. A thermal capacity of air inside the refrigerated volume is estimated, e.g. a time constant. Then the setpoint temperature for the air inside the refrigerated volume is changed, and the air temperature inside the refrigerated volume is monitored. A thermal capacity of the foodstuff stored in the refrigerated volume, e.g. a time constant, is estimated, based on the monitored air temperature and on the estimated thermal capacity of the air inside the refrigerated volume. The refrigeration system is controlled at least partly on the basis of the estimated thermal capacity of the foodstuff stored in the refrigerated volume.
