    • A high efficiency refrigeration system for saving energy and a control method thereof are provided to operate a compressor requiring high power at a low compression rate by maximally utilizing a heat source of a condenser, thereby increasing operation efficiency of the compressor. A refrigerant liquid pressure control valve(101) controls a high pressure refrigerant liquid to refrigerant supply pressure proposed for capacity selection of an expansion valve(8). A gas/liquid heat exchanger(102) removes flash gas generated by decompression of the high pressure refrigerant liquid of the pressure control valve and carries out heat exchange between refrigerant gas of low temperature and low pressure and the refrigerant liquid, wherein the refrigerant gas is converted to a low temperature and low pressure state from the high pressure refrigerant liquid from which the fresh gas is removed while passing through an electronic valve(7) for a liquid pipe, the expansion valve, and an evaporator(1).

    • PURPOSE: To reduce the necessary quantity of an enclosed refrigerant. CONSTITUTION: A first check valve 620 is mounted in a hot gas pathway 600 for guiding a refrigerant discharged from a compressor 100 to an evaporator 300, bypathing a discharger 200 and an ejector 400. The first check valve 620 allows the refrigerant to flow from the compressor 100 only toward the evaporator 300 (a refrigerant pathway 510). Accordingly, as the refrigerant is prevented from flowing into the hot gas pathway 600 in the normal operation, the refrigerant flowing into the hot gas pathway 600 from the low pressure side is prevented from residing (sleeping) in the hot gas pathway 600 during the normal operation, so that the necessary quantity of the enclosed refrigerant can be reduced and the manufacturing cost of the ejector cycle can be reduced.
    • 目的:减少必要数量的封闭制冷剂。 构成:第一止回阀620安装在热气通道600中,用于通过使排放器200和喷射器400通过路径将从压缩机100排出的制冷剂引导到蒸发器300.第一止回阀620允许制冷剂从 压缩机100仅朝向蒸发器300(制冷剂通路510)。 因此,由于在正常运转时阻止制冷剂流入热气通路600,所以在正常运转期间阻止从低压侧流入热气体通路600的制冷剂在正常状态下停留(睡觉)在热气体通路600中 从而可以减少所需量的封闭制冷剂,并且可以降低喷射器循环的制造成本。
