Abstract
Refrigeration system used for both cooling and freezing food, e.g. in a supermarket, comprises a freezing system(12) and a chilling system(14) with flow circuits for recirculation of separate refrigerants, each of the flow circuits comprising a shared evaporator (30) that is shared by the freezing system and the chilling system and provides a separate flow path through the evaporator for each of the refrigerants of the freezing system and the chilling system. The evaporator may selectively be coupled into the flow circuit of the freezing system allowing the refrigerant of the freezing system to flow through the evaporator cooling the surroundings to a freezing temperature, e.g. -180C, and the evaporator may selectively be coupled into the flow circuit of the chilling system allowing the refrigerant of the chilling system to flow through the evaporator cooling the surroundings to a chilling temperature, e .g.40C . In this way, the evaporator may selectively cool the surroudings to a freezing temperature with the efficiency of the freezing system and cool the surroundings to a chilling temperature with the efficiency of the chilling system.
