Problems solved by technology
[0003] During the process of assembling the four-way valve into the outdoor unit, since the three nozzles (i.e. S nozzle, E nozzle and C nozzle) at the bottom of the four-way valve have the same diameter and are arranged side by side, it is difficult for the assembler to weld. It is easy to happen that the nozzle of the four-way valve is not connected to the corresponding pipeline in the outdoor unit by welding, that is, the assembler welds the nozzle of the four-way valve incorrectly, which will cause the heat pump air conditioner to not operate normally, and then affect the system. reliability

The invention relates to the technical field of air conditioners, and discloses a pipe connection error judging method and a device of a four-way valve and a machine readable storage medium. The pipeconnection error judging method comprises the steps of: an air conditioner operation testing step (S1): an air conditioner is controlled to respectively work in a heating mode or a refrigerating mode,and an exhaust temperature of an indoor unit (10) and an exhaust temperature of an outdoor unit (20) are respectively acquired; and a judging step (S2): according to the acquired exhaust temperatures, when the air conditioner dose not perform heating in the heating mode and / or dose not perform refrigeration in the refrigerating mode, the pipe connection of the four-way valve (21) of the air conditioner is wrong. The pipe connection error judging method analyzes and judges if the pipe connection of the four-way valve of the air conditioner is wrong according to the acquired exhaust temperatures, so that producers of the air conditioner are convenient to perform the targeted treatment, pipe orifices of the four-way valve of the air conditioner are connected with corresponding pipelines in awelding manner, and the system reliability is improved.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a method and device for judging a connection error of a four-way valve of an air conditioner, and a machine-readable storage medium. Background technique [0002] At present, in the heat pump air conditioner, the four-way valve inside is reversing to change the flow direction of the refrigerant, so that the functions of the indoor heat exchanger and the outdoor heat exchanger in the air conditioner are interchanged, thereby realizing The purpose of the cold and warm exchange of the air conditioner, therefore, the four-way valve is a more important part in the whole machine. [0003] During the process of assembling the four-way valve into the outdoor unit, since the three nozzles (i.e. S nozzle, E nozzle and C nozzle) at the bottom of the four-way valve have the same diameter and are arranged side by side, it is difficult for the assembler to weld. It is eas...
