    摘要： A refrigeration system, includes a compressor, a condenser (200), a throttle flow path (100), and an evaporator (300) connected in sequence. A non-adjustable main throttle element (110,120) is disposed in the throttle flow path. A bypass flow path (500) is connected to the throttle flow path respectively at the upstream and downstream of the main throttle element, and provided with an adjustable auxiliary throttle element (510) thereon. A liquid level sensor is disposed upstream or downstream of the throttle flow path, and configured to detect the liquid level. A controller is configured to control the opening of the auxiliary throttle element according to a liquid level signal from the liquid level sensor.

    摘要： A system comprises the integrated combination of: a condenser having a condenser water path leg extending from a water inlet to a water outlet; a first expansion device; a flash tank economizer; a second expansion device; an evaporator having an evaporator water path leg extending from a water inlet to a water outlet; and a refrigerant flowpath passing sequentially through the condenser, the first expansion device, the economizer, the second expansion device and the evaporator. The flash tank economizer comprises a horizontally elongate body having a first end and a second end. The economizer has an inlet conduit having an outlet. The economizer has a liquid outlet, a vapor outlet, and a medium between the outlet of the inlet conduit and the liquid outlet. A length of the refrigerant flowpath between the first expansion device and the outlet of the inlet conduit is at least 0.5 m.

    摘要： A refrigeration system and a lubricating method thereof. The refrigeration system (100) includes: a compressor (110), a condenser (120), an evaporator (130), and a lubrication circuit (200), the lubrication circuit including a post-lubrication flow path (230,240,260) connected from the compressor into the condenser and the evaporator respectively; and a pre-lubrication flow path (210,220,250) connected from the condenser and the evaporator into the compressor respectively; wherein after flowing from the condenser via the pre-lubrication flow path to the compressor for lubrication, a part of refrigerant for lubrication can flow back to the evaporator via the post-lubrication flow path; or after flowing from the evaporator via the pre-lubrication flow path to the compressor for lubrication, the part of refrigerant for lubrication can flow back to the condenser via the post-lubrication flow path.
