The invention provides a refrigerating cycle system and refrigerating equipment. The refrigerating cycle system comprises a compressor, a condenser, a throttling device, an evaporator and an ejector, the ejector is arranged between the inlet of the condenser and the outlet of the compressor, and a return pipe is further arranged between the outlet of the condenser and the ejector; the throttling device is arranged between the outlet of the condenser and the inlet of the evaporator, and the outlet of the evaporator is connected with the inlet of the compressor. The ejector is arranged in front of the inlet of the condenser, the return pipe is utilized to eject part of return fluid of the outlet of the condenser, saturated refrigerant steam is at the inlet of the condenser, the coefficient of heat transfer of the condenser is increased, heat transfer performance of the condenser is improved obviously, and further refrigeration performance of the refrigerating equipment is improved.
Description
Technical field [0001] The invention relates to refrigeration equipment, in particular to a refrigeration cycle system and refrigeration equipment. Background technique [0002] Refrigeration equipment (refrigerators, freezers, etc.) are widely used in people’s daily lives. Refrigeration equipment usually includes compressors, evaporators, condensers and throttling devices. Compressors, evaporators, condensers and throttling devices are connected Together they constitute a refrigeration cycle system. In the refrigeration cycle system, when the refrigerant is throttled by the capillary tube, the gas-liquid two-phase refrigerant with a certain degree of dryness directly enters the evaporator. As the refrigerant flows, the liquid refrigerant evaporates continuously. As the gas rate gradually increases, the wettable area in the evaporator tube is continuously reduced, the heat transfer coefficient in the evaporator tube gradually decreases, and the overall heat transfer coefficient i...
