A kind of flashing type economizer and its distribution method

Abstract

The invention discloses a flash-type economizer and a material distributing method using the same. A gas equalizing plate is arranged above the liquid pipe, and gas blocking plates are arranged at both ends of the gas equalizing plate. Below the air equalizing plate is the float valve assembly. The float valve assembly is installed in the liquid outlet casing, and the liquid outlet casing is welded on the cylinder body. The two sides of the float valve assembly are equipped with a buffer plate with a hole at the bottom. The cylinder body is connected to the liquid outlet sleeve. A float chamber is welded on the opposite side of the pipe, and the float chamber is sealed with a flange on which a sight glass is provided. When the economizer is running, the liquid level is stable and reliable, and the adjustment is quick and efficient when the operating conditions change. It adopts the casing installation method, which is easy to disassemble and maintain, and the overall cost is low.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a flash economizer and a cloth distribution method using the same. Background technique [0002] The economizers used in high-efficiency cold water (heat pump) units in the refrigeration and air-conditioning industry mainly include two types of evaporators: plate-exchange economizers and flash-type economizers. Among them, compared with plate-exchange economizers, flash-type economizers have With the advantages of small heat transfer temperature difference and high system efficiency, the application prospect of flash economizer is more extensive. According to the different liquid level control methods of the economizer, the flash economizer can be divided into a float valve type and an electronic expansion valve type. Among them, the float type means that the liquid level in the economizer is controlled by the float valve, that is, the float moves with the cha...

AI Technical Summary

Problems solved by technology

The current flash economizer has the following disadvantages: 1) Due to the violent internal liquid flow of the float valve type flash economizer, the working state of the float valve is not stable enough and is easy to be damaged, resulting in the risk of liquid in the economizer, and due to The float valve must be built inside the economizer cylinder, and it is difficult to disassemble and maintain; 2) The electronic expansion valve type flash economizer uses electronic feedback, and its adjustment speed is slow, and it will appear when the operating conditions of the unit fluctuate. Insufficient adjustment causes the economizer to not work normally, and its cost is high
