Thus, even if the installer has no installation experience, the installation condition of the air conditioner can be easily known.
It should be noted that, when the judgment result and the prompt message are output, or after the operation is continued for m minutes, the operation has no fault, and the default state is normal, the whole detection process is completed, and the detection flow of the air conditioner is exited.
As a possible embodiment, the temperature of the evaporator and the temperature of the condenser of the air conditioner may also be detected, and the detection control of the air conditioner may be performed according to the temperature of the evaporator and the temperature of the condenser. For example, the temperature of the evaporator and the temperature of the condenser may be detected instead of the indoor and outdoor environment temperatures described above.
For convenience of understanding, the method for detecting an air conditioner according to an embodiment of the present invention will be described with reference to fig. 3, in which after the quick-check function is turned on, an indoor ambient temperature value T1 is detected by a temperature sensor provided at an indoor unit, an outdoor ambient temperature value T2 is detected by a temperature sensor provided at an outdoor unit, and an exhaust temperature value TP of the air conditioner is detected by a temperature sensor provided at an exhaust port of the air conditioner.
Further, T1 Initially, the method comprises (i.e., indoor ambient temperature value), T2 Initially, the method comprises (i.e., outdoor ambient temperature value), respectively. After the cooling operation is started, the entering temperature interval (for example, the temperature interval of TI in table 1 is (a, b), (b, c), (c, d), (d, e), and the temperature interval of T2 is (f, g), (g, h), (h, i), (i, j)) may be determined according to T1 Initially, the method comprises 、T2 Initially, the method comprises , so as to obtain the cooling operation parameters of the air conditioner, such as the operation frequency Fx, the inner fan rotation speed P Inner part , the outer fan rotation speed P Outer part , and the electronic expansion valve opening EXV.

Further, after T minutes of operation, the temperature sensor can detect once every m seconds, for example, three times, and average to obtain the parameters of the air conditioner after operation according to the refrigeration operation parameters, which are respectively recorded as an indoor environment temperature value T1 Inspection and detection 1, an outdoor environment temperature value T2 Inspection and detection 1 and an exhaust temperature value TP Inspection and detection 1 of the air conditioner. If the temperature interval in which T1 Inspection and detection 1 (i.e., the indoor environment temperature value) falls is the same as the temperature interval in which T1 Initially, the method comprises (i.e., the indoor environment temperature value) falls, and the temperature interval in which T2 Inspection and detection 1 (i.e., the outdoor environment temperature value) falls is also the same as the temperature interval in which T2 Initially, the method comprises (i.e., the outdoor environment temperature value) falls, it may be further determined whether TP Inspection and detection 1 (i.e., the air-conditioner exhaust temperature value after running with the cooling operation parameters) is greater than the corresponding temperature interval TPmax (i.e., the preset exhaust temperature), where TPmax may be obtained according to the temperature interval in which T1 Inspection and detection 1、T2 Inspection and detection 1 falls in table 1, if it is greater than TPmax, pushing first prompt information to display the information indicating that the air-conditioner is installed abnormally, such as a poor vacuum or a small refrigerant, according to the first prompt information, the installer may know that the air-conditioner is installed abnormally, or otherwise pushing second prompt information to display screen display the air-conditioner, which indicates that the air-conditioner is installed normally, and according to the second prompt information, the installer may know that the air-conditioner is installed normally. Thus, even if the installer has no installation experience, the installation condition of the air conditioner can be easily known.
Further, if the temperature interval in which T1 Inspection and detection 1 (i.e., the indoor ambient temperature value) falls is not the same as the temperature interval in which T1 Initially, the method comprises (i.e., the indoor ambient temperature value) falls, or the temperature interval in which T2 Inspection and detection 1 (i.e., the outdoor ambient temperature value) falls is not the same as the temperature interval in which T2 Initially, the method comprises (i.e., the outdoor ambient temperature value) falls, the air conditioner is controlled to operate again in the cooling mode. After operation is carried out for t2 minutes, refrigeration operation parameters of the air conditioner, such as operation frequency Fx 2, inner fan rotating speed P Inner part 2, outer fan rotating speed P Outer part 2, electronic expansion valve opening EXV 2 and the like, of the air conditioner, which is operated in a refrigeration mode next time, are obtained. After T2 minutes of operation, the sample can be detected once every m seconds, three times, and the average is taken as T1 Inspection and detection 2、T2 Inspection and detection 2、TP Inspection and detection 2. If the operation interval in which the T1 Inspection and detection 2、T2 Inspection and detection 2 falls is the same as the previous falling interval corresponding to the T1 Inspection and detection 1、T2 Inspection and detection 1, determining whether TP Inspection and detection 2 is greater than the corresponding operation interval TPmax, and if so, pushing the prompt message to the internal machine for display to indicate that the vacuum degree is poor or the refrigerant is less, otherwise, pushing the prompt message to the internal machine for display to indicate that the detection is normal. If the operation interval in which T1 Inspection and detection 2、T2 Inspection and detection 2 falls is different from the operation interval corresponding to the last T1 Inspection and detection 1、T2 Inspection and detection 1, the air conditioner is controlled to operate again in the cooling mode.
It should be noted that, when the judgment result and the prompt message are output, or after the operation is continued for m minutes, the operation has no fault, and the default state is normal, the whole detection process is completed, and the detection flow of the air conditioner is exited.
In summary, the detection method of the air conditioner determines whether the installation of the air conditioner is normal or not by detecting the indoor environment temperature, the outdoor environment temperature, the exhaust temperature of the air conditioner before and after the air conditioner operates according to the refrigeration operation parameters and the exhaust temperature after the air conditioner operates according to the refrigeration operation parameters, and can rapidly detect the operation state of the air conditioner system of the quick connecting pipe type, thereby avoiding damage to the air conditioning system caused by factors such as air mixing or serious few refrigerants and ensuring the operation reliability of the air conditioning system.

Specifically, the temperature sensor can detect once every m seconds, for example, three times, and average to obtain parameters before the air conditioner operates with the refrigeration operation parameters, which are respectively recorded as an indoor environment temperature value T1 Initially, the method comprises , an outdoor environment temperature value T2 Initially, the method comprises and an exhaust temperature value TP Initially, the method comprises of the air conditioner, and parameters after the air conditioner operates with the refrigeration operation parameters are respectively recorded as an indoor environment temperature value T1 Inspection and detection 1, An outdoor ambient temperature value T2 Inspection and detection 1 and an air-conditioner discharge temperature value TP Inspection and detection 1. The temperature interval (which can be obtained from the temperature intervals (a, b), (b, c), (c, d), (d, e) of T1 and the temperature intervals (f, g), (g, h), (h, i), (i, j) of T2 in the table 1) in which T1 Inspection and detection 1、T2 Inspection and detection 1 falls and the temperature interval (T1 Initially, the method comprises (i.e. indoor environment temperature value) before the air conditioner in the step S102 is operated with the cooling operation parameters) can be determined by the determination module 40, T2 Initially, the method comprises (i.e., outdoor ambient temperature value) falls within a temperature range (from the temperature ranges of TI in Table 1, which are (a, b), (b, c), (c, d), (d, e), T2 is (f, g), (g, h), (h, i), a temperature range of (c, d, e), (i, j) comparing, if the temperature interval in which T1 Inspection and detection 1 (i.e. the indoor environment temperature value) falls is different from the temperature interval in which T1 Initially, the method comprises (i.e. the indoor environment temperature value) falls, or the temperature interval in which T2 Inspection and detection 1 (i.e. the outdoor environment temperature value) falls is different from the temperature interval in which T2 Initially, the method comprises (i.e. the outdoor environment temperature value) falls, controlling the air conditioner to operate again in the cooling mode, and according to the operation interval determined by T1 Inspection and detection 1、T2 Inspection and detection 1, acquiring the cooling operation parameter of the air conditioner to operate in the cooling mode next time, such as the operation frequency Fx 2, Inner fan speed P Inner part 2, outer fan speed P Outer part 2, electronic expansion valve opening EXV 2, and the like.
Further, if the temperature interval in which T1 Inspection and detection 1 (i.e., the indoor environment temperature value) falls is the same as the temperature interval in which T1 Initially, the method comprises (i.e., the indoor environment temperature value) falls, and the temperature interval in which T2 Inspection and detection 1 (i.e., the outdoor environment temperature value) falls is also the same as the temperature interval in which T2 Initially, the method comprises (i.e., the outdoor environment temperature value) falls, it may be further determined whether TP Inspection and detection 1 (i.e., the air-conditioner exhaust temperature value after running with the cooling operation parameter) is greater than the corresponding temperature interval TPmax (i.e., the preset exhaust temperature), where TPmax may be obtained according to the temperature interval in which T1 Inspection and detection 1、T2 Inspection and detection 1 falls in table 1, if TPmax is greater than TPmax, a first prompt message indicating that the air-conditioner installation is abnormal, such as poor vacuum or low refrigerant, according to the first prompt message, the installer may know that the air-conditioner installation is abnormal, or a second prompt message indicating that the air-conditioner installation is normal, according to the second prompt message, the installer may know that the air-conditioner installation is normal. Thus, even if the installer has no installation experience, the installation condition of the air conditioner can be easily known.
