C:/NRPortbI/DCC/LGL/4026604_ .DOC-26/02/20l3 A carbon dioxide (C0 2) based refrigeration system including a primary refrigeration circuit 5 cycling C0 2, the primary refrigeration circuit including a main condenser and an auxiliary heat exchanger. The auxiliary heat exchanger being for reducing the temperature of CO2 flowing out of the main condenser. The auxiliary heat exchanger is independently operable with respect to the primary refrigeration circuit such that when the temperature of CO2 flowing out of the main condenser is at or above a threshold temperature, the auxiliary 10 heat exchanger operates to reduce the temperature of the CO 2. |
