Method for manufacturing gas collecting tube component and air-conditioning system

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...

AI Technical Summary

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 control and sustainable development under the circumstances of high copper prices and increasingly scarce copper resources.

[0007] Due to the many welding points of the air collecting pipe assembly parts in the current technology, the mutual thermal influence is relatively large, and the air tightness is difficult to control

At the same time, the surface quality after flame brazing is poor, and necessary pickling is required, which will have a greater impact on the environment
