Fig. 1 is a flowchart of an intelligent commissioning method of an air conditioner according to an embodiment of the present invention. As shown in fig. 1, the intelligent commissioning method of the air conditioner in this embodiment includes:
s101, entering a trial run, if the accumulated running time of the air conditioner identification compressor is less than or equal to 5h, judging that the compressor is started for the first time, and turning to S102; the air conditioner recognizes that the accumulated running time of the compressor is more than 5h, judges that the compressor is not started for the first time, and shifts to a step S103;
s102, judging whether the indoor air inlet side detection temperature C is greater than 20 ℃, and if so, turning to the step S104; otherwise, go to step S105;
s103, judging whether the number of times of using the refrigeration mode is more than that of the heating mode in nearly 2 days, and if so, turning to the step S104; otherwise, go to step S105;
in the embodiment, for an air conditioner with a cooling or heating mode, firstly, whether the air conditioner is started by a user for the first time is judged, and if the air conditioner is started for the first time, the cooling or heating mode is judged by adopting the indoor temperature of a user site; if the air conditioner is not started for the first time, the mode which is required by the air conditioner is judged according to the mode which is used by the user most frequently recently.
S104: refrigerating the high air at 16 ℃, meanwhile, detecting the frequency of a compressor by a unit, judging whether the difference C-A between the indoor air inlet side detection temperature C and the indoor air outlet temperature A is greater than a preset refrigerating threshold value or not when the compressor runs to the highest frequency and is stabilized for 3min, if so, turning to the step S106, otherwise, turning to the step S107; the preset refrigeration threshold value is determined according to the numerical values of the indoor air inlet side detection temperature C and the outdoor side detection temperature D;
s105: heating high air to run at 32 ℃, simultaneously, detecting the frequency of a compressor by a unit, judging whether the difference A-C between an indoor air outlet temperature value A and an indoor air inlet side detection temperature C is greater than a preset heating threshold value or not when the compressor runs to the highest frequency and is stabilized for 3min, if so, turning to step S106, otherwise, turning to step S107; the preset heating threshold value is determined according to the numerical values of the indoor air inlet side detection temperature C and the outdoor side detection temperature D;

s107: and judging that the air conditioner does not reach the standard, and displaying the difference value between the mark of not reaching the standard and the indoor side air inlet and outlet temperature by the panel.
After detecting the temperature of the air conditioner to operate, the air conditioner starts to detect whether the operating temperature index meets the preset condition. According to the machine testing method, because the machine testing function is integrated into the air conditioner, no external detection equipment is needed in the detection process, so that the home test of a user is facilitated, the home maintenance caused by subjective judgment is avoided, and the cost of manpower and material resources is saved.
Preferably, in step S104, in the cooling mode, the damper swings upward, and the cold air discharged from the air conditioner drops from above because the cold air is heavy, and thus the cold air can be better circulated indoors.
Preferably, in the step S105, in the heating mode, the air guide door swings downward, and hot air from the air conditioner is relatively light, so that hot air from the air conditioner can be circulated better indoors from bottom to top.
In the step S104, the indoor outlet air temperature value a is obtained by detecting the temperature B by the indoor coil sensor, and during refrigeration: a is B + a, wherein a is a preset compensation value set by a program; the value range of a is 2-5.
In step S105, the indoor outlet air temperature value a is obtained by detecting the temperature B by the indoor coil sensor, and during heating: a is B-a, wherein a is a preset compensation value set by a program; the value range of a is 5-8.
The intelligent machine testing method of the invention adopts the difference value of the indoor air inlet side detection temperature and the indoor air outlet temperature value to reflect the temperature control capability of the air conditioner, and judges whether the air conditioner operation capability reaches the standard or not by comparing the difference value with the preset refrigeration threshold value and the preset heating threshold value. The preset refrigeration threshold and the preset heating threshold are determined according to the value of the outdoor side detection temperature D, and the method specifically comprises the following steps, referring to table 1:

In one embodiment, T1 is 35 ℃, when the outdoor detection temperature D is higher than 35 ℃, the weather is hot, T3 is 15 ℃, when the difference between the indoor and the outdoor temperature values of the air inlet side detection temperature is greater than 15 ℃, the air-conditioning refrigeration capacity is qualified, when the outdoor detection temperature D is less than 35 ℃, the air-conditioning refrigeration capacity is improved compared with the hot weather, T4 is 18 ℃, that is, when the difference between the indoor air outlet temperature value and the air inlet side detection temperature is greater than 18 ℃, the air-conditioning refrigeration capacity is judged to be qualified.
When the air conditioner is in a heating mode:
if D is larger than T2, the preset heating threshold is a first preset heating threshold T5;
if D is less than T2, the preset heating threshold is a second preset heating threshold T6;
wherein the value range of T2 is 4-10 ℃, the value range of T5 is 23-27 ℃, and the value range of T6 is 18-22 ℃. In one embodiment, the value of T2 is 7 ℃, when the outdoor detection temperature is less than 7 ℃, the weather is cold, and the value of T6 is set to be 20 ℃; when the difference between the indoor air outlet temperature value and the air inlet side detection temperature is greater than 20 ℃, judging that the heating capacity of the air conditioner is qualified; when the outdoor detection temperature is higher than 7 ℃, the heating capacity of the air conditioner is improved compared with that of the air conditioner in cold weather, T5 takes a value of 25 ℃, namely, when the difference between the indoor air outlet temperature value and the detection temperature of the air inlet side is higher than 15 ℃, the heating capacity of the air conditioner is judged to be qualified.
