Problems solved by technology

[0006] With the continuous development of industrial technology, the use of commercial air conditioners that require a large cooling ton capacity is also increasing. As a large cooling ton air conditioning system, the pressure of the medium circulation system is relatively high, and the airtight pressure is required to be increased. The copper material The main air-collecting pipe assembly is bulky and consumes a lot of copper materials. This is not conducive to cost con

Embodiment Construction

[0044] The technology of the present invention will be described below in conjunction with specific embodiments.

[0045] In order to facilitate the description of the technical solution of the present invention, the same numbers are used for the same parts of the present invention and the prior art.

[0046] Please refer to image 3 , Figure 4 , image 3 A schematic structural view of the gas collecting pipe assembly provided by the present invention, Figure 4 A schematic cross-sectional view of the main air collecting pipe provided by the present invention;

[0047] The air collecting pipe assembly 107 is composed of the main air collecting pipe 1 as the main structure. The main air collecting pipe 1 is generally in the shape of a hollow round rod, and several stepped flanges 11 are processed on the pipe wall. The main air collecting pipe 1 can be a straight pipe as shown in the figure. According to the connection requirements, a bend can be provided at one or both end...

Abstract

The invention relates to a method for manufacturing a gas collecting tube component. The method comprises the following steps of: 1) preparing a main gas collecting tube made of a stainless steel material; 2) preparing a plurality of gas collecting branch tubes made of carbon steel materials; 3) fixing the main gas collecting tube, the gas collecting branch tubes and a tube orifice sealing cap obtained in the steps 1 and 2 through interference or transition fit; and 4) welding the assembled parts to form the gas collecting tube component. The invention also provides an air-conditioning system. The material manufacturing cost can be greatly reduced; and meanwhile, according to novel materials, a novel method for manufacturing the gas collecting tube component is adopted, the airtight reliability and corrosion resistance of the product are improved, the process is simplified, the pickling step is canceled, and the environmental pollution can be avoided through the pickling process.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a method for manufacturing an air collecting pipe assembly and an air conditioning system using the air collecting pipe assembly. Background technique [0002] Air conditioning or other forms of heat pump refrigeration systems in the prior art mainly include functional components such as a compressor 101, a first heat exchanger 102, a second heat exchanger 103, and a throttling element 104, and the airtight communication of each functional component forms The pipeline connector 105 of the medium circulation path, such as figure 1 shown. Its working principle is as follows: After the air-conditioning system is powered on, the low-pressure steam of the refrigerant in the refrigeration system is sucked by the compressor 101 and compressed into high-pressure steam, and then discharged to the second heat exchanger 103 (condenser), while the outdoor air sucked by the...
