Rectification nozzle type equal flow liquid separator and refrigeration system

Abstract

The invention discloses a rectifying nozzle type equal-flow liquid distributor and a refrigeration system, and provides a liquid distributor and a refrigeration system capable of realizing equal liquid supply in each flow path of an evaporator and improving the heat exchange performance of the evaporator. The liquid separator includes a two-phase flow liquid supply pipe, a fluid rectifier and a liquid separator. There is a liquid supply chamber and a ring-shaped distribution chamber on the circumference of the liquid distribution chamber. The ring-shaped distribution chamber is divided into multiple distribution chambers by partitions. Each distribution chamber There is a liquid distribution pipe on the top, and a distribution nozzle is installed in each distribution chamber; there are swirl vanes inside the two-phase flow liquid supply pipe, the outlet of the two-phase flow liquid supply pipe is connected to the inlet of the fluid rectifier, and the outlet of the fluid rectifier is connected to the liquid supply pipe. The cavity is connected; the distribution chamber, the split nozzle and the liquid distribution pipe are arranged in a circular array with the center line of the annular distribution chamber as the center, and the center line of the distribution chamber, the split nozzle and the liquid distribution pipe is in a straight line. The liquid separator can realize equal flow liquid supply in each branch, thereby improving the heat transfer performance of the evaporator and the performance of the refrigeration system.

Description

technical field [0001] The invention relates to the technical field of refrigeration, and more specifically relates to a rectifying nozzle type equal-flow liquid separator and a refrigeration system. Background technique [0002] In the refrigeration system, the evaporator with direct expansion liquid supply usually adopts the form of multi-flow parallel connection to achieve the best heat exchange effect, maintain the best refrigerant flow rate, and limit the pressure loss of the pipeline within a certain range . The gas-liquid two-phase flow of the 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 distribute it equally to each flow. on the road. In the refrigeration system, the refrigerant two-phase flow distribution equipment is usually called a liquid distributor or liquid separator. [0003] The liquid separator shoul...
