[0027] Obviously, the accompanying drawings described below are merely some embodiments of this disclosure. Those skilled in the art can obtain other drawings based on these drawings without any creative effort.

[0033] Figure 6 A schematic diagram of the structure of a connecting pipe mounting device according to some embodiments of the present disclosure is shown. Detailed Implementation

[0034] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0035] Unless otherwise stated, the terms "first," "second," etc., used in this disclosure are used to distinguish different objects and are not used to indicate size or sequence.

[0036] Figure 1 This diagram shows the correct piping connection for a dual-system unit air conditioning unit.

[0037] like Figure 1 As shown, the dual-system unitary air conditioning unit includes: Air Conditioning System 1 (hereinafter referred to as System 1) and Air Conditioning System 2 (hereinafter referred to as System 2), as well as four connecting pipes. Air Conditioning System 1 includes Compressor 1, Outdoor Heat Exchanger 1, Indoor Heat Exchanger 1, Outdoor System 1 Liquid Pipe, Indoor System 1 Liquid Pipe, Outdoor System 1 Gas Pipe, and Indoor System 1 Gas Pipe. The Outdoor System 1 Liquid Pipe and the Indoor System 1 Liquid Pipe are connected by a connecting pipe. The Outdoor System 1 Gas Pipe and the Indoor System 1 Gas Pipe are connected by a connecting pipe. Similarly, Air Conditioning System 2 includes Compressor 2, Outdoor Heat Exchanger 2, Indoor Heat Exchanger 2, Outdoor System 2 Liquid Pipe, Indoor System 2 Liquid Pipe, Outdoor System 2 Gas Pipe, and Indoor System 2 Gas Pipe. The Outdoor System 2 Liquid Pipe and the Indoor System 2 Liquid Pipe are connected by a connecting pipe. The Outdoor System 2 Gas Pipe and the Indoor System 2 Gas Pipe are connected by a connecting pipe.

[0038] The correct way to connect pipes is as follows Figure 1 As shown, each air conditioning system is independent of the others. The pipes between the indoor and outdoor units correspond one-to-one and cannot be connected incorrectly; otherwise, the air conditioning unit will not be able to operate normally.

[0039] However, due to the long and numerous pipes in multi-system unit air conditioning units, it is difficult to determine the correspondence between the two ends of the pipes after they are laid, which can easily lead to pipe connection errors. Figure 2A , 2B Figure 2C shows a schematic diagram of incorrect piping connections in a dual-system unit air conditioning unit.

[0040] To address the aforementioned issues, this disclosure provides a multi-system unit air conditioning unit comprising: multiple air conditioning systems and multiple connecting pipes, each connecting pipe connecting the indoor and outdoor sides of one air conditioning system. Specifically: the connecting pipe on the first side of any air conditioning system is connected to the port on the first side of one of the multiple connecting pipes; the connecting pipe on the first side of any air conditioning system is equipped with a shut-off valve and an injection port for injecting gas; the port on the second side of the connecting pipe from which gas flows out is connected to the connecting pipe on the second side of any air conditioning system. The first side is one of the outdoor and indoor sides, and the second side is the other of the outdoor and indoor sides. The type of the connecting pipe on the first side of any air conditioning system is the same as the type of the connecting pipe on the second side of any air conditioning system, including, for example, liquid pipes and gas pipes. Thus, the liquid pipes on the indoor and outdoor sides of the same air conditioning system are connected via connecting pipes, and the gas pipes on the indoor and outdoor sides of the same air conditioning system are connected via connecting pipes.

[0041] The gas cylinder is connected to the injection port via a gas tube. Opening the valve on the gas cylinder allows gas to be injected through the tube into the injection port. Injected gases may include, but are not limited to, inert gases and refrigerants. Nitrogen can be a suitable inert gas. If welding is used for the pipe connections, nitrogen provides protection during welding, preventing the copper pipes (liquid and gas pipes are copper) from directly contacting air at high temperatures, which could lead to oxide scale formation, impurities in the pipes, and blockages.

[0042] Figure 3 A schematic diagram illustrating the installation method of the connecting pipe according to some embodiments of this disclosure is shown.

[0043] like Figure 3 As shown, the installation method of the connecting pipe in this embodiment includes:

[0044] In step 310, the pipe to be connected on the first side of any air conditioning system in the multi-system unit air conditioning unit is connected to the port on the first side of one of the multiple connecting pipes. The pipe to be connected on the first side of any air conditioning system is provided with a shut-off valve and an air injection port.

[0045] The first side is one of the outdoor side and the indoor side, and the second side mentioned later is the other of the outdoor side and the indoor side.

[0046] In step 320, the valve of the gas tank is opened, and the gas in the gas tank is injected into the gas tank through the gas tube from the gas inlet. The gas flows out through the stop valve, the port on the first side of the connecting pipe, and the port on the second side of the same connecting pipe.

[0047] In some embodiments, injecting gas from the injection port includes: injecting gas from the injection port at a first pressure to determine a port on the second side of the connecting pipe from which gas flows out; then, injecting gas from the injection port at a second pressure, wherein the high-pressure gas purges any impurities that may be present in the connecting pipe to remove impurities from the connecting pipe, wherein the second pressure is greater than the first pressure.

[0048] In step 330, the port on the second side of the connecting pipe from which gas flows out is connected to the connecting pipe on the second side of any of the air conditioning systems.

[0049] Wherein, the type of the pipe to be connected on the first side of any air conditioning system is the same as the type of the pipe to be connected on the second side of any air conditioning system. The types of pipes to be connected include, for example, liquid pipes and gas pipes. Thus, the liquid pipes on the indoor and outdoor sides of the same air conditioning system are connected by connecting pipes, and the gas pipes on the indoor and outdoor sides of the same air conditioning system are connected by connecting pipes.

[0050] In some embodiments, the ports on the first side and the second side of the connecting pipe are marked with the same mark according to the pipe to be connected in any of the air conditioning systems, so that the connection can be made based on the mark.

[0051] For example, assuming that the pipe to be connected in any of the air conditioning systems is the System 1 liquid pipe, the outdoor port of the selected connecting pipe of the System 1 liquid pipe is marked as "System 1 liquid pipe", and the indoor port of the same connecting pipe determined by gas injection is also marked as "System 1 liquid pipe". The outdoor port of the connecting pipe marked as "System 1 liquid pipe" is connected to the outdoor liquid pipe of System 1, and the indoor port of the connecting pipe marked as "System 1 liquid pipe" is connected to the indoor liquid pipe of System 1.

[0052] The pipe connection methods in the various embodiments of this disclosure include, but are not limited to, welding, threaded connection, etc.

[0053] The above embodiments enable accurate determination of pipeline connection methods before the air conditioning unit valves are opened, effectively guiding on-site installation work.
