However, while the popularization of air conditioners provides people with a comfortable working and living environment, some disadvantages have gradually emerged, which are mainly reflected in the initial installation process, especially in densely populated areas where air conditioners are installed. When setting up a multi-connected system, there may be a phenomenon that the refrigerant connection pipe of the indoor unit is connected to the outdoor unit system A, but the communication connection line is connected to the outdoor unit system B, and the installation of the outdoor unit and the indoor unit is chaotic.

The invention provides a multi-split system diagnosis method and a multi-split system. The multi-split system diagnosis method is applied to the multi-split system. The multi-split system comprises multiple outer units and multiple inner units. The multi-split system diagnosis method comprises the steps of detecting operation modes of the outer units, and detecting the temperatures inside heat exchangers of the inner units connected with the outer units; detecting the temperature of the indoor environment where the inner units are located; and comparing the temperatures inside the heat exchangers with the environment temperature according to the operation modes of the outer units, and judging whether connection between the outer units and the inner units is wrong or not according to the comparison result. By means of the multi-split system diagnosis method and the multi-split system, whether connection between the outer units and the inner units of the multi-split system is correct ornot can be judged; the problem that the inner units and the outer units of different multi-split systems are connected disorderly when the multiple multi-split systems are mounted is found; maintenance workers are informed of conducing repair and troubleshooting in time; the situation that equipment is destroyed due to the fact that wrong connection between the inner units and the outer units is not found in time is avoided; and reliability of the multi-split system is improved.
Description
technical field [0001] The present invention relates to the field of air conditioners, and more particularly, to a method for diagnosing a multi-line system and a multi-line system. Background technique [0002] Nowadays, air conditioners are gradually popularized in daily home life. However, while the popularization of air conditioners has given people a comfortable working and living environment, some drawbacks have gradually emerged, mainly reflected in the initial installation process, especially in the dense areas where air conditioners are installed. Specifically, there are many installations on the same floor. When a multi-connection system is set up, the indoor unit refrigerant connection pipe may be connected to the A outdoor unit system, but the communication cable is connected to the B outdoor unit system. This kind of disorderly installation of the outdoor unit and the indoor unit occurs. [0003] Therefore, it is an urgent problem to design a multi-connection s...
