    摘要： A refrigeration apparatus performs heat exchange on a water tube system having a water inlet tube leading exterior water to a water branching point, first and second branching water tubes extending from the water branching point, and a water outlet tube leading to the exterior from a convergent point of the first and second branching water tubes. Active refrigerant is in a supercritical state in at least part of a refrigeration cycle. The refrigeration apparatus includes a main expansion mechanism connected to an evaporator, first and second compression elements connected by a first refrigerant tube, a first heat exchanger exchanging heat between the first refrigerant tube and the first branching water tubes, second refrigerant tubes connecting the second compression element and the main expansion mechanism, and a second heat exchanger in which the second refrigerant tubes exchange heat with the second branching water tubes and does not exchange heat with the water inlet tube.

    摘要： A refrigerating apparatus, where refrigerant reaches a supercritical state in at least part of a refrigeration cycle, includes at least one expansion mechanism, an evaporator connected to the expansion mechanism, first and second sequential compression elements, a radiator connected to the discharge side of the second compression element, a first refrigerant pipe interconnecting the radiator and the expansion mechanism, a heat exchanger arranged to cause heat exchange between the first refrigerant pipe and another refrigerant pipe. Preferably, a heat exchanger switching mechanism is switchable so that refrigerant flows in the first refrigerant pipe through the first heat exchanger or in a heat exchange bypass pipe connected to the first refrigerant pipe. Alternatively, a heat exchanger switching mechanism increases refrigerant flowing through a second expansion mechanism when an air temperature at the evaporator and/or a compressed refrigerant temperature detected is higher and/or lower than predetermined values.
