The invention discloses a split-phase refrigerating fluid gas-liquid dispenser and a refrigerating system. The dispenser and the refrigerating system can guarantee that the refrigerating fluid flow of all flow paths is the same and can achieve same-dryness liquid supply. The dispenser is composed of a gas-liquid two-phase flow liquid supply pipe, an annular sealing pipeline, a liquid header and a plurality of split-phase branches. An outlet of the gas-fluid two-phase flow liquid supply pipe is connected with an inlet of the annular closed pipeline. A liquid pipe and a gas pipe in each split-phase branch are symmetrically connected with the annular closed pipeline, wherein the liquid pipe is mounted on the lower portion of the annular closed pipeline, and the gas pipe is mounted on the upper portion of the annular closed pipeline. The liquid pipe of each split-phase branch is connected with an inlet of the liquid header, and the liquid header is connected with an inlet of a liquid distribution pipe. An outlet of the liquid distribution pipe is connected with a liquid inlet of a mixer, and a gas outlet of each gas pipe is connected with a gas inlet of the mixer. All the flow paths of an evaporator are supplied together, the heat exchange performance of the evaporator is improved, and the performance of the refrigerating system is improved.
Description
technical field [0001] The invention relates to the technical field of refrigeration, and more particularly, to a phase-separating gas-liquid separator and a refrigeration system. Background technique [0002] In the refrigeration system, the evaporator that directly expands the liquid supply usually adopts the form of multi-channel parallel connection to achieve the best heat exchange effect, maintain the best refrigerant flow rate, and limit the pipeline pressure loss within a certain range. . The gas-liquid two-phase flow of refrigerant coming out of the expansion valve is usually in the form of bubble flow or slug flow. Two-phase flow distribution equipment is required to fully mix the gas-liquid two-phase refrigerant, and then distribute the same amount to each flow. on the road. In refrigeration systems, the refrigerant two-phase flow distribution equipment is usually referred to as a liquid distributor or a liquid distributor. [0003] The liquid separator should a...
