[0002] The background technology of ground source heat pump central air conditioning gas collecting pipe originates from the demand for efficient and stable heat exchange system, and its core lies in achieving flow balance between underground buried pipe heat exchanger loops and stable system operation through reasonable design of gas collecting pipe shape and layout. Ground source heat pump system utilizes underground shallow geothermal resources (such as soil, underground water or surface water) as cold and heat source, and realizes energy transfer from low temperature level to high temperature level through heat pump principle. In this process, gas collecting pipe, as a key component connecting multiple parallel buried pipe heat exchanger loops, is responsible for collecting and distributing circulating medium (such as water or antifreeze). Its design needs to consider fluid dynamics characteristics, system layout, installation convenience and cost, etc. to ensure small pressure loss of medium flowing in pipe, balanced flow, avoid local overheating or overcooling phenomenon, and thus guarantee efficient and stable operation of the whole ground source heat pump system.

However, in actual engineering application, when the length of a single gas collecting pipe cannot meet the installation requirements, two gas collecting pipes need to be butt-jointed through welding process. In this process, the contact parts of the two gas collecting pipes must be welded; however, the traditional welding method is to manually find and position welding points along the butt-joint circumference by welding gun, which not only has low efficiency, but also is difficult to ensure uniform consistency of weld quality; therefore, it cannot meet the existing requirements, and thus we propose a ground source heat pump central air conditioning gas collecting pipe positioning welding equipment.
