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.

Claim (Index 2):
The method according to  claim 1 , further comprising the steps of, in the case that the pressure difference is lower than the first lower threshold value:\n obtaining a difference between the derived reference pressure value and the selected fixed reference pressure value, comparing the obtained difference to a second upper threshold value, and in the case that the obtained difference is higher than the second upper threshold value, selecting the derived reference pressure value, and controlling the vapour compression system according to the derived reference pressure value, and in order to obtain a pressure of refrigerant leaving the heat rejecting heat exchanger which is equal to the derived reference pressure value.
