Abstract

The invention provides a flash type economizer, comprising a shell, a front end board and a back end board, wherein the front end board and the back end board are respectively sealed and covered at the opposite ends of the shell; an input pipe and a liquid outlet pipe are arranged at the lower part of the shell; an air supply pipe is arranged at the upper part of the shell; the flash type economizer further comprises a partition board arranged inside the shell and parallel to an axis direction of the shell, and at least two baffles located between the input pipe and the liquid outlet pipe and connected between the bottom face of the partition board and the shell at an interval; and the baffles are provided with openings in a staggered manner left and right, so that a baffling channel which is roundabout left and right is formed in each baffle. The liquid-phase refrigerating fluid is roundabout left and right through the baffles, so that severe fluctuation is weakened by the baffles, and the influence of the liquid-phase refrigerating fluid continuously surging into a surge area on the liquid level fluctuation is reduced to the lowest. Therefore, the liquid seal of the liquid outlet pipe is ensured, and the filling amount of the refrigerating fluid can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and air conditioning, and in particular relates to a flash economizer. Background technique [0002] Flash economizer (also known as flash tank, power saver, flash power saver) is an energy-saving device used by chillers in the refrigeration and air-conditioning industry. In the compression two-stage throttling refrigeration system, the flash economizer is usually set after the first-stage throttling device, the refrigerant liquid passes through the first-stage throttling device to throttle and flash, and the gas-liquid two-phase refrigerant enters the In the shell of the flash economizer, part of the refrigerant liquid evaporates in the shell of the economizer, and the refrigerant gas generated by flash and evaporation returns to the high-pressure stage of the two-stage compressor or the joint compression of the two-stage compressor through the air supply pipe. Compressed again in the high...
