[0033] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0035] The operating principle of the air conditioner involved in the embodiment of the present application is described in detail below:

[0036] like Figure 1 As shown in the figure, the compressor compresses the refrigerant (coolant) and transports it to the condenser through a pipeline. The high-temperature and high-pressure gaseous refrigerant releases heat in the condenser and becomes a medium-temperature and high-pressure liquid refrigerant. After that, the medium-temperature and high-pressure liquid refrigerant is depressurized by a capillary tube (throttling unit) and becomes a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant is transported to the evaporator to evaporate from liquid to gas, and absorbs a large amount of heat during the evaporation process. Finally, the low-temperature and low-pressure gaseous refrigerant in the evaporator is transported to the compressor to participate in the next cycle. When the air conditioner is cooling, the heat exchanger of the outdoor unit is the condenser, and the heat exchanger of the indoor unit is the evaporator; conversely, when the air conditioner is heating, the heat exchanger of the outdoor unit is the evaporator, and the heat exchanger of the indoor unit is the condenser.

[0037] In order to be able to accurately control the air conditioner when in use, the maximum performance parameters of the air conditioner (including: the maximum operating power and maximum operating current of the air conditioner, etc.) need to be known before the air conditioner leaves the factory (especially new air conditioners). In the related art, most of them are manual measurements, which are costly and have poor accuracy. Based on this, the embodiment of the present application provides a method for measuring the maximum power and maximum current of an air conditioner, which realizes automatic measurement through measuring equipment that is respectively connected to the air conditioner to be tested and the working condition machine for communication, which not only reduces the measurement cost, but also improves the measurement efficiency and measurement accuracy.

[0038] The following is a detailed description of the method for measuring the maximum power and maximum current of the air conditioner provided in the embodiment of the present application through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0039] like Figure 2 As shown, an embodiment of the present application provides a method for measuring the maximum power and maximum current of an air conditioner, and the method may include the following steps 201 and 202:

[0040] Step 201: Acquire measurement data of the air conditioner to be tested by sending corresponding control instructions to the air conditioner to be tested and the working condition machine.

[0041] Among them, the measurement data includes: the operating power and operating current of the air conditioner under different operating temperatures and different input voltages; the control instructions sent by the measuring device to the air conditioner under test include: a first control instruction, a second control instruction, a third control instruction and a fourth control instruction; the first control instruction is used to initialize the input voltage; the second control instruction is used to initialize the operating temperature; the third control instruction is used to increase the input voltage; the fourth control instruction is used to increase the operating temperature.

[0042] It should be noted that, in the embodiment of the present application, when the air conditioner is being measured, the indoor unit and the indoor unit of the air conditioner to be tested are respectively located in different working condition rooms, and the measuring device can adjust the working temperature in the working condition room. The measuring device is respectively connected to the air conditioner to be tested and the working condition machine in communication, and the input voltage of the air conditioner to be tested can be adjusted by controlling the variable frequency power supply of the air conditioner to be tested, and the working condition temperature can be adjusted by controlling the working condition machine. At the same time, the measuring device can also obtain the operating power and operating current of the air conditioner to be tested in real time through the communication connection with the air conditioner to be tested.

[0043] Exemplarily, the working temperature is the ambient temperature of the working room where the outdoor unit of the air conditioner to be tested is located. In the embodiment of the present application, the temperature of the working room where the indoor unit is located is constant at 27°C, and the ambient temperature of the working room where the outdoor unit is located varies in the range of 36°C to 46°C. In the embodiment of the present application, the adjustment of the working temperature is the adjustment of the ambient temperature of the working room where the outdoor unit is located.

[0044] Specifically, the above step 201 may include the following steps 201a1 and 201a2:

[0045] Step 201a1, when the air conditioner is not in operation, sending the first control instruction to the air conditioner to be tested and sending the second control instruction to the operating condition machine to control the air conditioner to be tested to power on and operate at the first input voltage at the lowest operating temperature.

[0046] Step 201a2: acquiring the power change of the air conditioner to be tested in real time, and when the power change rate of the air conditioner to be tested is less than a preset change rate threshold, recording the operating power and operating current of the air conditioner to be tested at the minimum operating temperature and the first input voltage.

[0047] The first input voltage is the product of the rated voltage of the air conditioner to be tested and a first multiple; the first multiple is less than 1.

[0048] Exemplarily, the first input voltage is the initialization voltage during the measurement process, and the first input voltage is also the lower limit of the input voltage adjustment value of the air conditioner to be measured during the measurement process, that is, the minimum input voltage; the minimum operating temperature is the initialization operating temperature. That is, the first control instruction is used to adjust the input voltage of the air conditioner to be measured to the first input voltage, and the second control instruction is used to adjust the operating temperature to the minimum operating temperature.

[0049] For example, Figure 3 As shown, after the measurement starts, the air conditioner to be tested is first controlled to operate at a voltage V=0.8*rated voltage (i.e., the first input voltage) at an operating temperature T=36°C (i.e., the above-mentioned minimum operating temperature) by sending a first control instruction to the air conditioner to be tested and a second control instruction to the operating conditioner. Afterwards, when the air conditioner is running stably (the judgment condition is that the rate of change of the power P of the air conditioner to be tested is less than 50 watts per minute w / min, i.e., the above-mentioned preset rate of change threshold), the operating power and operating current of the air conditioner to be tested at the minimum operating temperature and the first input voltage are recorded.

[0050] Specifically, the above step 201 may further include the following steps 201b1 and 201b2:

[0051] Step 201b1, when the input voltage of the air conditioner under test is less than the second input voltage, send the third control instruction to the air conditioner under test to control the air conditioner under test to increase the input voltage of the air conditioner under test according to the target voltage increment based on the current input voltage.

[0052] Exemplarily, the second input voltage is the upper limit of the input voltage adjustment value of the air conditioner under test during the measurement process, that is, the maximum input voltage. When the current input voltage of the air conditioner under test is less than the second input voltage, the input voltage needs to be increased and then measured again.

[0053] Step 201b2, acquiring the power change of the air conditioner to be tested in real time, and when the power change rate of the air conditioner to be tested is less than the preset change rate threshold, recording the operating power and operating current of the air conditioner to be tested under the current operating temperature and current input voltage.

[0054] Among them, the second input voltage is the product of the rated voltage of the air conditioner to be tested and a second multiple; the second multiple is greater than 1; the target voltage increment is the product of the rated voltage of the air conditioner to be tested and the target multiple; the target multiple can be divided by a target multiple difference integer; the target multiple difference is the difference between the second multiple and the first multiple.

[0055] For example, Figure 3 As shown, after completing a measurement, if the input voltage V of the air conditioner to be tested is less than 1.2*rated voltage (i.e., the second input voltage mentioned above), a third control instruction needs to be sent to the air conditioner to be tested to increase the input voltage of the air conditioner to be tested and re-measure the operating power and operating current.

[0056] Specifically, the above step 201 may further include the following steps 201c1 and 201c2:

[0057] Step 201c1, when the input voltage of the air conditioner to be tested is equal to the second input voltage and the operating temperature of the air conditioner to be tested is lower than the maximum operating temperature, send the first control instruction to the air conditioner to be tested, and send the fourth control instruction to the operating machine to control the air conditioner to be tested to operate according to the first input voltage at the increased operating temperature.

[0058] Step 201c2, obtaining the power change of the air conditioner to be tested in real time, and when the power change rate of the air conditioner to be tested is less than the preset change rate threshold, recording the operating power and operating current of the air conditioner to be tested under the current operating temperature and the first input voltage.

[0059] For example, after the operating temperature is adjusted, the input voltage needs to be reinitialized in order to obtain the operating power and operating current corresponding to each input voltage of the air conditioner to be tested under the new operating temperature.

[0060] For example, Figure 3 As shown, after completing a measurement, if the operating temperature T is less than 46°C (i.e., the above-mentioned maximum operating temperature), it is necessary to send a fourth control instruction to the operating machine to increase the operating temperature (by 1°C each time). At the same time, a first control instruction is sent to the air conditioner to be tested to initialize the input voltage of the air conditioner to be tested, and re-measure the operating power and operating current.

[0061] Exemplarily, by cyclically executing the above steps 201b1, 201b2, 201c1 and 201c2, the operating power and the operating current of the air conditioner under different operating temperatures and different input voltages can be obtained.

[0062] Specifically, the above step 201 may further include the following step 201d:

[0063] Step 201d: When the input voltage of the air conditioner to be tested is equal to the second input voltage and the operating temperature of the air conditioner to be tested is equal to the maximum operating temperature, end the measurement of the air conditioner to be tested.

[0064] For example, in the embodiment of the present application, the process of the input voltage from the lowest input voltage to the highest input voltage is the input voltage cycle, and the process of the operating temperature from the lowest operating temperature to the highest operating temperature is the operating temperature cycle. The input voltage cycle is nested in the operating temperature cycle, that is, each time the operating temperature changes, an input voltage cycle needs to be executed. After the above operating temperature cycle is executed, the entire measurement process can be terminated.

[0065] It should be noted that in the embodiment of the present application, after adjusting the input voltage and operating temperature of the air conditioner to be tested, it is necessary to re-perform the measurement step to obtain the operating power and operating current of the air conditioner to be tested under different operating temperatures and different input voltages. The measurement steps are the same each time, that is, when the rate of change of the operating power of the air conditioner to be tested is less than the preset rate of change threshold, the relevant data is recorded.

[0066] In a possible implementation, the above-mentioned measuring device can also display the current measurement progress in real time on the display screen, including: current input voltage, current operating temperature and other related information.

[0067] Specifically, the above step 201 may further include the following step 201e:

[0068] Step 201e: Displaying the current measurement progress information in real time on the display screen of the measuring device.

[0069] The measurement information includes at least one of the following: the input voltage at the current moment, and the operating temperature at the current moment.

[0070] It is understandable that each new air conditioner needs to be measured before leaving the factory, so the measurement method must be compatible with all air conditioners. In the embodiment of the present application, the method of measuring the air conditioner by the measuring device only requires a program that can execute the corresponding control instructions and feedback the operating power and operating current to be built into the air conditioner, and the maximum operating power and maximum operating current can be measured using the measurement method provided in the embodiment of the present application. Good compatibility and less changes to the air conditioner.

[0071] Step 202: Filter out the maximum operating power and the maximum operating current, and the operating temperature and input voltage corresponding to the maximum operating power and the maximum operating current from the measurement data.

[0072] For example, after the operating power and operating current of the air conditioner to be tested under different operating temperatures and different input voltages are obtained, the maximum operating power and the maximum operating current, as well as the corresponding operating temperature and input voltage, can be screened out.

[0073] Specifically, the above step 202 may include the following steps 202a:

[0074] Step 202a, compare the operating power and operating current corresponding to each operating temperature, and filter out the maximum operating power, the first operating temperature corresponding to the maximum operating power, and the first input voltage, as well as the maximum operating current, the second operating temperature corresponding to the maximum operating current, and the second input voltage.

[0075] It should be noted that the operating temperature corresponding to the maximum operating power and the operating temperature corresponding to the maximum operating current may be the same or different; the input voltage corresponding to the maximum operating power and the input voltage corresponding to the maximum operating current may be the same or different. That is, the first operating temperature and the second operating temperature may be the same or different; the first input voltage and the second input voltage may be the same or different.

[0076] The method for measuring the maximum power and maximum current of an air conditioner provided in the embodiment of the present application, first, by sending corresponding control instructions to the air conditioner to be tested and the working condition machine, the measurement data of the air conditioner to be tested is obtained; the measurement data includes: the operating power and operating current of the air conditioner to be tested under different working temperature and different input voltage; then, the maximum operating power and the maximum operating current, as well as the working temperature and input voltage corresponding to the maximum operating power and the maximum operating current are screened out from the measurement data; wherein, the control instructions sent by the measuring device to the air conditioner to be tested include: a first control instruction, a second control instruction, a third control instruction and a fourth control instruction; the first control instruction is used to initialize the input voltage; the second control instruction is used to initialize the working temperature; the third control instruction is used to increase the input voltage; the fourth control instruction is used to increase the working temperature. In this way, the input voltage and working temperature can be automatically adjusted by the measuring device, and the system stability judgment and data parameter recording can be performed, which greatly improves the measurement efficiency and measurement accuracy.

[0077] It should be noted that the method for measuring the maximum power and maximum current of the air conditioner provided in the embodiment of the present application can be executed by a device for measuring the maximum power and maximum current of the air conditioner, or a control module in the device for measuring the maximum power and maximum current of the air conditioner for executing the method for measuring the maximum power and maximum current of the air conditioner.
