Claim 11:
12. The method according to claim 1, wherein the refrigerant cycle comprises a by-pass line connected between the flash tank and the suction port of the compressor, wherein the by-pass line comprises a by-pass valve, and wherein the method further comprises:
determining, via the controller, that the pressure of the flash tank is lower than the second threshold and closing the by-pass valve; or
determining, via the controller, that the pressure of the flash tank is equal to or greater than the second threshold and lower than a third threshold, and determining, by the controller, a value for an opening degree of the by-pass valve based on the determined flash tank pressure; or
determining, via the controller, that the pressure of the flash tank is equal to or greater than the third threshold and lower than a fourth threshold, and opening the by-pass valve completely; or
determining, via the controller, that the pressure of the flash tank is equal to or greater than the fourth threshold and setting an opening degree of the by-pass valve to a predetermined value.
