Abstract: A refrigeration device containing CO2 a refrigerant to be circulated, including a compressor, a heat-rejecting heat exchanger, an expansion, and an evaporator which are connected to one another. The refrigeration device includes a first portion and a second portion, the second portion having a higher temperature relative to the first portion when the refrigeration device is in operation. A heat-reclaim heat exchanger is provided at a given location in the second portion, provided to transfer heat to a fluid for further use as a source of heated fluid.

Abstract: A Refrigerating system (2) comprises a refrigerating circuit (4) having, in flowing direction, a compressor (8), a gas cooler (10), a first expansion device (12), an intermediate pressure container (14), a second expansion device (16), an evaporator (18) and refrigerant conduits (22, 24, 26, 28, 30, 32) circulating a refrigerant therethrough. The first expansion device (12) expands the refrigerant to an intermediate pressure level. A first refrigerant conduit (22) of the refrigerant conduits (22, 24, 26, 28, 30, 32) connects the compressor (8) and the gas cooler (10), and a second refrigerant conduit (24) of the refrigerant conduits (22, 24, 26, 28, 30, 32) connects the gas cooler (10) and the first expansion device (12), the first refrigerant conduit (22), the gas cooler (10), and the second refrigerant conduit (24) forming a transcritical portion of the refrigerating circuit (4).
