Features illustrated or described in connection with one exemplary embodiment may be combined with features of other embodiments. Such modifications and variations are intended to be included within the scope of the present invention.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, a detailed description of related known functions or configurations is omitted to avoid unnecessarily obscuring the technical points of the present invention. In addition, the same reference numerals refer to the same circuits, modules or units throughout the description, and repeated descriptions of the same circuits, modules or units are omitted for brevity.
Further, it should be understood that one or more of the following methods or aspects thereof may be performed by at least one control unit or controller. The term "control unit" or "controller" may refer to a hardware device that includes a memory and a processor. The memory is configured to store program instructions, and the processor is specifically configured to execute the program instructions to perform one or more processes that will be described further below.

Fig. 1A is a flowchart illustrating a method of confirming an operation state of an air conditioner according to an embodiment of the present invention, and referring to fig. 1A, the method includes:
100': and acquiring the indoor environment temperature difference and the machine temperature difference caused by the air conditioner operation target time. Wherein the machine temperature difference can be characterized by the indoor tube temperature difference.
102': and determining the running state of the air conditioner based on whether the indoor environment temperature difference and the corresponding first threshold value and the machine temperature difference and the corresponding second threshold value simultaneously meet the target condition. The operation state of the air conditioner comprises normal operation of the air conditioner or abnormal operation of the air conditioner; or comprises the following steps: and the air conditioner operates normally or not in a specific working mode. In the case where the air conditioner is normally operated (normal in all the operation modes), it can be determined that there is no abnormality in the installation of the air conditioner.
Compared with the prior art that the running state of the air conditioner is judged/detected only according to the indoor environment temperature difference, the method provided by the embodiment can more accurately determine the running state of the air conditioner after installation (in a test running stage) by simultaneously considering the indoor environment temperature difference representing the working effect of the air conditioner and the machine temperature difference of the state of the air conditioner, and further effectively determine whether the air conditioner is abnormally installed. For example, after an after-market installation, the validity and quality of the installation can be effectively and uniformly evaluated.
The method provided by the embodiment of the invention is suitable for testing the household air conditioner after installation, and can also be applied to testing the air conditioner for vehicles and ships after installation.
In one embodiment of the invention, process 100' may be implemented as follows:
and a, responding to a trial operation instruction to acquire the current indoor environment temperature. The specific test operation instruction may be sent by an infrared/bluetooth/radio frequency remote controller, a manual operator/wire controller, or WiFi, which is equipped with the air conditioner, through a specific operation mode, and the specific operation mode is not limited in the present invention. The test run command herein refers to a command in a test stage after the air conditioner is installed.
In the present embodiment, "performing action y in response to condition x" may be understood as performing action y at the time condition x occurs or within a set time after condition x occurs.
Step b: determining an operating mode based on the current indoor ambient temperature. If the current indoor ambient temperature is in a relatively low temperature region (set region), the operation mode of the heating mode is entered, and if the current indoor ambient temperature is in a relatively high temperature region (set region), the operation mode of the cooling mode is entered. The operation mode mentioned herein refers to a trial operation mode for detecting whether the air conditioner is abnormally installed after the air conditioner is installed, and accordingly, the heating mode and the cooling mode refer to heating and cooling during trial operation and should not be understood as heating and cooling when the air conditioner is normally operated.
Step c: and operating the target time in the working mode, acquiring the indoor environment temperature and the machine temperature before and after operation, and calculating to obtain the indoor environment temperature difference and the machine temperature difference.
Further, if it is determined that the indoor ambient temperature difference is greater than the first threshold and the machine temperature difference is greater than the second threshold, it is determined that the air conditioner is normally operated in the operation mode.
As previously described, the operation modes include a heating mode and a cooling mode. The first threshold and the second threshold correspond to an operating mode. That is, the heating mode has corresponding first and second thresholds (refer to table 4 below), and the cooling mode has corresponding first and second thresholds (refer to table 6 below). In one embodiment of the present invention, if the operation state of the air conditioner in the two modes is to be determined instead of only the operation state in the current mode, after the operation state of the air conditioner in one of the heating mode and the cooling mode is determined, a transition state of a set time is passed, and the air conditioner is switched to the other one of the heating mode and the cooling mode and whether the air conditioner can be normally operated in the other one is determined. The adverse effect on the air conditioner caused by the switching of the two modes can be effectively avoided through the transition state, and the effectiveness of the evaluation result can be guaranteed. Wherein the transition state may be shutdown, standby, etc.
In an exemplary embodiment of the present invention, step c may be implemented by:
in response to the operational load of the air conditioner completing the start-up, an initial indoor ambient temperature and an initial machine temperature are recorded. After the target time, for example, after the compressor in the operation load of the air conditioner is operated for the target time, the target indoor ambient temperature and the target machine temperature are recorded. And determining the indoor environment temperature difference and the machine temperature difference according to the target indoor environment temperature, the target machine temperature, the initial indoor environment temperature and the initial machine temperature.
The running load of the air conditioner comprises a compressor, an inner machine air deflector, an inner machine fan, an outer machine fan and a four-way valve. Depending on the operating mode of the air conditioner. Specifically, the operation load of the air conditioner completes the start, including: starting the compressor; opening the inner air deflector to a set angle (e.g., a minimum angle); starting an inner fan and an outer fan according to the operation mode corresponding to the working mode; wherein, when the mode of operation is the mode of heating, still include: the four-way valve is started.
In some cases, for example, in cold regions, the current outdoor ambient temperature may be obtained before the internal air deflector is turned on; and if the current outdoor environment temperature is smaller than the corresponding threshold value, starting an electric heating function of the compressor to heat for a set time, then starting an air deflector of the internal machine to a set angle and carrying out subsequent treatment. Therefore, the air conditioner is protected in a preheating mode in a cold environment, the validity of the evaluation result of the running state of the air conditioner in a test running state is improved, and the accuracy of the result of determining whether the air conditioner is installed abnormally according to the running state of the air conditioner is improved.
In an embodiment of the present invention, the inner fan and the outer fan need to be controlled to operate according to an operation mode corresponding to the operation mode. For example, in the heating mode, the rotation speed of the internal fan is adjusted according to a first indoor temperature interval (for an example, refer to table 2 below, which has 3 temperature intervals) to which the real-time indoor ambient temperature belongs; in the heating mode, the rotation speed of the multi-wind-gear/rotation-speed outer machine fan is adjusted or the start of the single-wind-gear/rotation-speed outer machine fan is controlled according to a second indoor temperature interval (an example refers to fig. 3 below, 2 temperature intervals between-15 ℃ and between 15 ℃ and 50 ℃ can be known according to S302/S306) to which the real-time indoor environment temperature belongs and a first outdoor temperature interval (an example refers to fig. 3 below, 3 temperature intervals for the multi-wind-gear/rotation-speed outer machine fan; 2 temperature intervals for the single-wind-gear/rotation-speed outer machine fan); in the cooling mode, the rotation speed of the internal fan is adjusted according to a third indoor temperature interval to which the real-time indoor environment temperature belongs (see table 5 below for an example, 3 temperature intervals are provided for a multi-wind-gear/rotation-speed external fan, and 3 temperature intervals are also provided for a single-wind-gear/rotation-speed external fan); in the cooling mode, the rotation speed of the multi-wind-gear/rotation-speed outer machine fan is adjusted or the start of the single-wind-gear/rotation-speed outer machine fan is controlled according to a second outdoor temperature range to which the real-time outdoor environment temperature belongs (see table 5 below for an example, the multi-wind-gear/rotation-speed outer machine fan has 3 temperature ranges, and the single-wind-gear/rotation-speed outer machine fan has 1 temperature range). By dividing the temperature interval and matching the temperature interval and the rotating speed, the effectiveness of the determined air conditioner running state (during the test running) is favorably ensured, and the accuracy of the result of whether the air conditioner is normally installed or not determined based on the air conditioner running state is further ensured.
For an example of the temperature zones and the rotation speed in this embodiment, please refer to the following description related to table 2, table 5 and fig. 3.

The method specifically comprises the following steps: if the rated heating capacity of the air conditioner does not exceed a first heating capacity threshold value (for example, 3500W), the four-way valve and the compressor are started simultaneously; if the rated heating capacity of the air conditioner is larger than the first heating capacity threshold value and does not exceed a second heating capacity threshold value (for example, 7200W), starting the four-way valve by delaying k (Q0-Q1) seconds after the compressor is started; if the rated heating capacity of the air conditioner exceeds a second heating capacity threshold value, starting the four-way valve in a time delay k (Q2-Q1) seconds after the compressor is started; wherein Q0 represents a rated heating capacity of the air conditioner, Q1 represents the first heating capacity threshold value, Q2 represents the second heating capacity threshold value, and k is a constant.
In an embodiment of the invention, in the operating mode, in the process of determining the operating state of the air conditioner, a fault detection mode is simultaneously adopted to detect whether a fault occurs in the operating process of the air conditioner. The fault detection mode may be an existing air conditioner fault detection mode, and the present invention is not limited thereto. By adopting the embodiment, whether the air conditioner has hidden danger or faults can be detected while the running state of the air conditioner is detected, and whether the air conditioner has faults or not does not need to be detected independently, so that the high efficiency of after-sale installation result evaluation is ensured.
In an embodiment of the present invention, the first threshold and the second threshold may be different according to different air conditioner operation modes (cooling/heating), and may have a strict correspondence relationship with a known parameter to ensure the validity of the finally confirmed air conditioner operation state. The known parameters include an initial indoor ambient temperature, an initial outdoor ambient temperature, and a difference therebetween. For example, an initial indoor ambient temperature, an initial outdoor ambient temperature may be recorded in response to the operational load of the air conditioner completing the start-up; and determining the first threshold value and the second threshold value according to a temperature interval to which the initial indoor environment temperature belongs, a temperature interval to which the initial outdoor environment temperature belongs, and a temperature interval to which a difference value between the initial outdoor environment temperature and the initial indoor environment temperature belongs. For the values of the first threshold and the second threshold, please refer to the following description about tables 4 and 6.
In one embodiment of the invention, a heating mode is entered when the current indoor ambient temperature is within a first relatively low temperature range (e.g., [ -15 ℃ -20 ℃)); the cooling mode is entered when the current indoor ambient temperature is within a second relatively high temperature range (e.g., (20 c-50 c)), wherein the first temperature range includes temperatures lower than 16 c, the second temperature range includes temperatures higher than 30 c, or the first temperature range includes temperatures higher than-15 c, and the second temperature range includes temperatures lower than 50 c, which is advantageous for facilitating rapid verification of the cooling or heating function of the air conditioner, solving the problems that the cooling function (or heating function) of the air conditioner cannot be rapidly verified in cold winter (or in hot summer), some loads that can be turned on only under specific temperature or logic conditions under cooling (or heating) may not be rapidly discovered if there is a malfunction, of course, the temperature set to enter the heating and cooling modes is not limited to the above examples, the flexible arrangement can be realized by the person skilled in the art according to the needs.
