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 11):
The method according to  claim 3 , wherein the step of deriving a reference pressure comprises using a look-up table providing corresponding values of temperature of refrigerant leaving the heat rejecting heat exchanger, pressure of refrigerant leaving the heat rejecting heat exchanger, and optimal coefficient of performance (COP) for the vapour compression system.
