In the related art, three temperature sensing bulbs are installed in an air conditioner indoor unit to measure the temperature of an inlet pipe, a middle pipe and an outlet pipe of an indoor heat exchanger (evaporator). Because the temperature sensing bags for measuring the pipe temperature in the multi-connected indoor unit are easy to be confused, the situation that the temperature sensors corresponding to all positions are inserted reversely is inevitable in the production and after-sale maintenance processes, in the air conditioner, the temperature information obtained by the controller generally directly corresponds to a specific temperature sensing bulb for detecting the temperature, that is, in general, if the temperature information detected by the inlet tube thermal bulb is directly identified as the temperature information of the inlet tube of the heat exchanger by the controller, and in case of the wrong insertion of the inlet tube thermal bulb, the identification of the temperature information is usually not corrected in time, so when the installation of each temperature sensing bulb is in trouble and the temperature information is uploaded by the temperature sensing bulbs at each position, the controller still corresponds the acquired error temperature information with the set position and controls the air conditioner, in this case, the temperature control is disabled, so that the air conditioning system operates abnormally, and the use of the air conditioning system is finally affected.
Based on the embodiment of the invention, when the air conditioner runs, the air conditioner can enter the temperature sensing bulb self-detection repairing mode, in the temperature sensing bulb self-detection repairing mode, whether the temperature sensing bulb correspondingly detecting the temperature of the first refrigerant opening, the temperature of the middle pipe and the temperature of the second refrigerant opening is correctly installed or not is judged by acquiring the temperature of the first refrigerant opening, the temperature of the middle pipe and the temperature of the second refrigerant opening of the indoor heat exchanger in the air conditioner and comparing the temperature with the temperature of the second refrigerant opening, and the temperature sensing bulb can be installed or the corresponding temperature information which is acquired and set can be repaired according to the judgment result, so that the abnormal running of the air conditioner caused by the installation error of the temperature sensing bulb can be prevented, and the use of a user is prevented from being influenced.
The multi-connected air conditioner system can enable the unit to enter a thermal bulb self-detection repairing mode after the air conditioner is installed and operated for the first time and after the air conditioner unit is operated for a first preset operation time without abnormality, wherein the first preset operation time is selectable to be 5-10min, so that errors in thermal bulb self-detection repairing caused by other abnormalities of the air conditioner are prevented.
In an optional embodiment of the present invention, the obtaining a first refrigerant port temperature, a middle pipe temperature, and a second refrigerant port temperature of an indoor heat exchanger in the air conditioner includes:
operating the air conditioner in a heating mode;

In the embodiment of the invention, when the air conditioner operates in a heating mode, the values of the first refrigerant port temperature, the middle pipe temperature and the second refrigerant port temperature are obtained, because the pipe temperature difference of the heat exchanger of the indoor unit is small and the phenomenon of liquid return exists during the cooling operation, the situation of misjudgment is possible, and the pipe temperature difference is relatively large in the heating mode, the misjudgment can be prevented, so that the detection can be more accurately carried out, and the subsequent repair is convenient.
After the air conditioner operates for a second preset operation time, the temperature is detected, so that the phenomenon that the refrigerant does not flow sufficiently due to too short operation time of the air conditioner and misjudgment occurs can be prevented, the second preset operation time can be set according to actual conditions, and in the embodiment, the second preset operation time can be selected to be 8-15 min.
After the air conditioner runs for the second preset running time, a plurality of pipe inlet temperatures, a plurality of pipe middle temperatures and a plurality of pipe outlet temperatures of the indoor heat exchanger in the first preset collection time are obtained, and corresponding average values are calculated according to the plurality of temperature values, so that the temperature can be detected more accurately, and misjudgment is prevented.
In general, the heat exchanger of the indoor unit is a coil type, which includes a first refrigerant port and a second refrigerant port, and when the indoor unit is in heating operation or cooling operation, the pipe temperatures are the same, and when the heating and cooling mode is switched, the refrigerant flow direction is reversed, the pipe inlet and outlet of the refrigerant are also reversed correspondingly.
