    Abstract: In a refrigerant cycle system with an ejector pump, refrigerant to be introduced into a nozzle of the ejector pump is heated in a heat exchanger using waste heat from a vehicle engine as a heating source, and any one of a first mode, a second mode and a third mode can be selectively set based on a thermal load of an evaporator. In the first mode, refrigerant circulates from the evaporator toward a radiator only by the ejector pump. In the second mode, refrigerant circulate from the evaporator toward the radiator only by a compressor. Further, in the third mode, refrigerant circulates from the evaporator toward the radiator by using both the ejector pump and the compressor. Accordingly, the waste heat can be effectively recovered while a flow resistance of the refrigerant can be restricted.

    Abstract: The present invention provides a cryogenic refrigerating system for achieving ultra low temperature by sequentially obtaining low temperature through repetition of expansion and evaporation of a mixed-refrigerant in multiple stages. The refrigerating system includes a heat exchanger and a compressor between a final evaporator and a compressor. The heat exchanger causes evaporated refrigerant vapor in a suction tube for the compressor to be heated and to be drawn into the compressor, and causes the refrigerant condensed by a condenser to be supercooled. The refrigerating system includes a plurality of expansion/suction apparatuses connected with one another between the gas/liquid separator and the final evaporator.

    Abstract: A process and apparatus for exchanging heat with condensable fluid are disclosed. In the process, a two-phase fluid is passed through the tubes of a heat exchanger under conditions of temperature and pressure such that the quality of the two-phase flow lies in the range of 0.03 to 0.97. The two-phase fluid is in a state of thermodynamic saturation at both the entry and exit of the heat exchanger. The change in quality of the two-phase mixture passing through the heat exchanger is distributed over the entire heat exchanger. The apparatus according to the invention includes a plurality of connected modular stages, each stage including a heat exchanger, a vapor-liquid separator, a compressor, an ejector and the suitable conduits to establish fluid communication between adjacent stages.
