  • Patent number: 11408654
    Abstract: The present invention provides an economizer, including a housing having a first section and a second section; and a condenser outlet, an evaporator inlet, and a compressor intermediate-stage inlet that are disposed on the second section of the housing; wherein the first section has a contour matching a housing of a commonly used condenser, such that the first section can fit the housing of the condenser. The economizer of the present invention can better match an outer contour of a conventional condenser, so that the both can fit each other in arrangement as much as possible when applied to an overall layout of a refrigeration system, thereby significantly reducing a transverse space occupied by the refrigeration system.

  • Patent number: 11408676
    Abstract: A system and method for cooling a gas using a mixed refrigerant includes a compressor system and a heat exchange system, where the compressor system may include an interstage separation device or drum with no liquid outlet, a liquid outlet in fluid communication with a pump that pumps liquid forward to a high pressure separation device or a liquid outlet through which liquid flows to the heat exchanger to be subcooled. In the last situation, the subcooled liquid is expanded and combined with an expanded cold temperature stream, which is a cooled and expanded stream from the vapor side of a cold vapor separation device, and subcooled and expanded streams from liquid sides of the high pressure separation device and the cold vapor separation device, or combined with a stream formed from the subcooled streams from the liquid sides of the high pressure separation device and the cold vapor separation device after mixing and expansion, to form a primary refrigeration stream.
