[0045] The refrigeration equipment mentioned below refers to equipment that is filled with refrigerant and can provide a refrigeration function based on the refrigerant. The refrigeration equipment includes but is not limited to refrigerators, freezers, air conditioners, etc.

[0046] In one embodiment, Figure 2 As shown, a refrigerant detection method is provided, which is applied to Figure 1 The following steps are taken as an example:

[0047] Step 202: obtaining a first power of a first refrigeration device when it is operated at a set temperature of a standard detection environment, and a plurality of second powers of the first refrigeration device when it is operated at a plurality of first temperatures.

[0048] The first refrigeration device is a refrigeration device with qualified refrigerant injection. The set temperature is a pre-set commodity inspection temperature, which can be set and modified according to commodity inspection items and requirements. The first temperature is a plurality of ambient temperatures different from the set temperature, and the second power of the first refrigeration device when it is running is obtained by detecting at the plurality of first temperatures.

[0049] Optionally, in a standard detection environment where the ambient temperature is a set temperature, the operating power of the first refrigeration device with qualified refrigerant perfusion is obtained to obtain the first power. The ambient temperature is adjusted, the first refrigeration device is operated based on the normal working mode, the second temperature is obtained through the ambient temperature detection sensor on the refrigeration device, and the second power of the first refrigeration device at the second temperature is obtained. By repeatedly adjusting the ambient temperature, multiple different second temperatures and second powers corresponding to the second temperatures are obtained.

[0050] Step 204 , fitting multiple first temperatures and second powers with the set temperature and the first power as constraints, to obtain correction parameters for correcting the powers detected at different temperatures.

[0051] The second power at the first temperature can be corrected based on the correction parameter so that the corrected second power is as close as possible to the power of the first refrigeration device when it is running at the set temperature. The more first temperatures and corresponding second powers there are, the more accurate the fitting result is, and the higher the accuracy of the obtained correction parameter is.

[0052] Optionally, with the set temperature and the first power as constraints, multiple first temperatures and multiple second powers are fitted so that the first temperature and the corresponding second power meet a preset functional relationship. The preset functional relationship can be obtained based on the correlation between the operating power of the refrigeration equipment and the ambient temperature. Specifically, the correlation between the operating power of the refrigeration equipment and the ambient temperature can be calculated based on the working principle of the refrigerator and the laws of thermodynamics; the correlation between the operating power of the refrigeration equipment and the ambient temperature can also be obtained through simulation, empirical formulas, etc.

[0053] Step 206: Correct the third power of the second refrigeration device when it is running under the current detection environment according to the second temperature of the current detection environment and the corresponding correction parameter.

[0054] Among them, the second refrigeration equipment is the equipment to be detected, and the structural structure of the second refrigeration equipment is the same as that of the first refrigeration equipment. Optionally, after the second refrigeration equipment is operated based on the normal working mode, the second temperature under the current detection environment is detected, and the third power of the second refrigeration equipment is detected. The third power is corrected in combination with the second temperature and the corresponding correction parameter. The degree of correction of the third power at different temperatures is different. According to the fitting results of the first temperature and the second power, the correction parameters of the power at different temperatures can be obtained, and the corrected third power can be obtained based on the correction parameters. Alternatively, according to the fitting results of the first temperature and the second power, a calculation formula for the correction parameters that change with temperature can be obtained, thereby obtaining a correction coefficient associated with the first temperature, and then obtaining a correction value of the third power. It can be understood that if the second temperature is the set temperature, there is no need to correct the third power.

[0055] Step 208: judging whether the refrigerant in the second refrigeration equipment is filled properly according to the corrected third power.

[0056] The corrected third power is close to the operating power of the second refrigeration equipment at the set temperature. Therefore, the corrected third power can be judged based on the judgment standard of the operating power of the second refrigeration equipment at the set temperature. If the corrected third power meets the power judgment standard of the second refrigeration equipment at the set temperature, it can be judged that the refrigerant filling of the second refrigeration equipment is qualified; if the corrected third power does not meet the power judgment standard of the second refrigeration equipment at the set temperature, it can be judged that the refrigerant filling of the second refrigeration equipment is unqualified.

[0057] In the above-mentioned refrigerant detection method, the operating power of the first refrigeration equipment at a set temperature is constrained, and the operating power of the refrigeration equipment at different temperatures and at different temperatures is fitted to obtain correction parameters for correcting the power of the refrigeration equipment. Based on the correction parameters, the operating power of the second refrigeration equipment at the second temperature is corrected, so that the corrected third power is close to the operating power of the second refrigeration equipment at the set temperature, so that the effect of accurately judging whether the refrigerant of the refrigeration equipment is filled with qualified can be achieved according to the corrected power.

[0058] In one embodiment, the first power and the second power are the compressor operating power of the first refrigeration equipment. With the set temperature and the first power as constraints, multiple first temperatures and second powers are fitted to obtain correction parameters for correcting the powers detected at different temperatures, including: with the preset temperature and the target power as constraints, the second power and the first temperature are fitted so that the second power and the first temperature satisfy a linear function relationship; and the power adjustment coefficient is obtained according to the parameters of the linear function after fitting.

[0059] Among them, since the suction and exhaust pressure of the compressor during the operation stage of the refrigeration equipment is basically linearly related to the ambient temperature, and the operating power of the compressor changes linearly with the change of the suction and exhaust pressure of the compressor during the operation stage, it can be deduced that the relationship between the power of the compressor and the ambient temperature is basically linear. Correspondingly, the third power of the second refrigeration equipment is the operating power of the compressor of the second refrigeration equipment. In this embodiment, the first temperature and the corresponding second power are fitted through a linear function relationship, so that the fitted temperature and power conform to the operating principle of the compressor of the refrigeration equipment, thereby improving the accuracy of whether the refrigerant of the refrigeration equipment is filled with qualified refrigerants.

[0060] In one embodiment, the correction parameters include a power adjustment constant and a temperature adjustment constant, wherein, after adjusting the preset power based on the power adjustment constant, and adjusting the set temperature and the first temperature respectively based on the temperature adjustment constant, the ratio between the adjusted preset power and the second power is equal to the ratio between the adjusted set temperature and the adjusted first temperature.

[0061] Among them, since the operating power of the refrigeration equipment is affected by the temperature, a temperature adjustment constant for adjusting the temperature can be obtained based on the corresponding relationship between the operating power and the temperature. After adjusting the first temperature and the set temperature respectively by the temperature adjustment constant, the ratio between the adjusted set temperature and the adjusted first temperature can be made to conform to the rate of change of power relative to temperature. Since the relationship between multiple powers of temperature change does not necessarily conform to a multiple relationship, a power adjustment constant can be obtained based on the corresponding relationship between power and temperature, and the ratio between the preset power adjusted based on the power adjustment constant and the second power also conforms to the rate of change of power relative to temperature, so that the ratio between the adjusted preset power and the second power is equal to the ratio between the adjusted set temperature and the adjusted first temperature.

[0062] In this embodiment, the correction parameter is obtained by two fixed constants, so that the operating power of the second refrigeration device at different detected ambient temperatures can be corrected by the two correction parameters, making the power correction method simple.

[0063] Furthermore, after obtaining the temperature adjustment constant, in one embodiment, based on the second temperature of the current detection environment and the corresponding correction parameter, the third power of the second refrigeration device detected under the current detection environment when it is running is corrected, including: obtaining a first difference between the second temperature and the temperature adjustment constant, and a second difference between the set temperature and the temperature adjustment constant; obtaining a power adjustment coefficient based on the first difference and the second difference; and correcting the third power of the second refrigeration device detected under the current detection environment when it is running based on the power adjustment constant and the power adjustment coefficient.

[0064] Optionally, the second temperature is subtracted from the temperature adjustment constant to obtain a first difference; the set temperature is subtracted from the temperature adjustment constant to obtain a second difference. The ratio between the first difference and the second difference is the rate of change of power relative to temperature, that is, the power adjustment coefficient can be obtained. After adjusting the third power by the power adjustment coefficient, the corrected third power is obtained in combination with the power adjustment constant.

[0065] In this embodiment, the power adjustment coefficient of the second temperature corresponding to the third power is calculated by the temperature adjustment constant, so that the third power is corrected according to the actual temperature of the environment where the second refrigeration equipment is located. The power correction method is simple and the calculation amount is small.

[0066] In one embodiment, with the set temperature and the first power as constraints, multiple first temperatures and second powers are fitted, and correction parameters for correcting the powers detected at different temperatures are obtained, including: a power adjustment constant and a temperature adjustment constant; wherein the power adjustment constant and the temperature adjustment constant are obtained by fitting based on the following formula:

[0067] P 设定 =P 测 / K+P 常

[0068] K = (TR1-R) / (TR)

[0069] Among them, P 设定 is the first power, P 测 is the second power, P 常 is the power adjustment constant, TR1 is the first temperature, R is the temperature adjustment constant, and T is the set temperature.

[0070] Optionally, multiple second powers corresponding to multiple first temperatures are obtained, and when the first power and the set temperature remain unchanged, the multiple second powers corresponding to the multiple first temperatures are substituted into the above two formulas to calculate the power adjustment constant and the temperature adjustment constant.

[0071] In one embodiment, the correction parameters include a power adjustment constant and a temperature adjustment constant. According to the second temperature of the current detection environment and the corresponding correction parameters, the third power of the second refrigeration equipment detected under the current detection environment when it is running is corrected, including: based on the difference between the second temperature and the temperature adjustment constant, and the ratio between the set temperature and the temperature adjustment constant, the power adjustment coefficient K is calculated, the third power is divided by the power correction coefficient, and the power adjustment constant is added to obtain the corrected third power. The specific formula is as follows:

[0072] P 修 =P 实 / K+P 常

[0073] K = (TR2-R) / (TR)

[0074] Among them, P 修 is the corrected third power, P is the third power, K is the power adjustment coefficient, P 常 is the power adjustment constant, TR2 is the third temperature, R is the temperature adjustment constant, and T is the set temperature.

[0075] In one embodiment, judging whether the refrigerant filling of the second refrigeration equipment is qualified according to the corrected third power includes: obtaining a preset power range when the second refrigeration equipment is operating at a set temperature; when the corrected third power is within the preset power range, judging that the refrigerant filling of the refrigeration equipment is qualified.

[0076] The preset power range is the operating power of the qualified refrigeration equipment at the set temperature. The first power of the first refrigeration equipment operating at the set temperature is within the preset power range.

[0077] Optionally, an upper threshold and a lower threshold of the third power are obtained according to the power operation range, and when the third power is greater than or equal to the lower threshold and less than or equal to the upper threshold, it is judged that the third power is within a preset power range, and the refrigerant filling of the refrigeration equipment is qualified. On the contrary, when the corrected third power is not within the preset power range, the refrigerant filling of the refrigeration equipment is unqualified.

[0078] If the third power is less than the lower limit threshold indicated by the preset power range, the refrigerant is overfilled; if the third power is greater than the upper limit threshold indicated by the preset power range, the refrigerant is underfilled.

[0079] In one embodiment, another refrigerant detection method is provided, and the refrigerant detection method is applied to a refrigerator as an example. The refrigerant detection environment is located in a commodity inspection room, and the ambient temperature of the commodity inspection room is set, that is, the set temperature in the above embodiment is 25°C.

[0080] Since the suction and exhaust pressure of the refrigerator compressor is basically linearly related to the ambient temperature during the initial operation of the refrigerator. When the suction pressure of the refrigerator compressor is low and the exhaust pressure of the refrigerator compressor is high, the operating power P of the refrigerator compressor is high; when the suction pressure of the refrigerator compressor is high and the exhaust pressure of the refrigerator compressor is low, the operating power P of the refrigerator compressor is low. It can be deduced that the operating power P of the refrigerator compressor and the ambient temperature can also be constrained using linearity, and the impact of ambient temperature changes on the power of the refrigerator compressor is obtained:

[0081] K=(TR-R) / (25-R)

[0082] Wherein, K is the power adjustment coefficient, R is the temperature adjustment constant, and 25 is the set temperature of the commercial inspection room. When the refrigerator starts to be powered on, the second temperature TR is collected by the ambient temperature sensor set in the refrigerator.

[0083] Furthermore, the power correction formula can be obtained according to the power adjustment coefficient:

[0084] P 修 =P 实 / K+P 常

[0085] Among them, P 实 is the measured refrigerator power, P 常 is the power adjustment constant, P 修 is the corrected refrigerator power.

[0086] Based on the above principle, the temperature adjustment constant and power adjustment constant used to correct the refrigerator power are obtained according to the power of the refrigerator when it is running at different temperatures, and then the refrigerator operating power obtained by the test in the commercial inspection room is corrected according to the temperature adjustment constant and power adjustment constant. If the preset power range of the refrigerator under normal operation state with qualified refrigerant filling is (Pl, Ph), then P 修 If it is within the range (Pl, Ph), it is judged as qualified;

[0087] For ease of understanding, for example, the commodity inspection judgment commodity inspection condition is set at 25°C, and the refrigerator operating power P satisfies 90W<P<100W, then the refrigerant filling is qualified. At the set temperature of 25°C, the refrigerator with qualified refrigerant filling, that is, the first refrigeration equipment, has a first power of 95W under normal operating conditions. When the ambient temperature is 30°C, the operating power of this refrigerator is detected to be 100W; when the ambient temperature is 35°C, the operating power is detected to be 105W. Here, the ambient temperatures of 30°C and 35°C are the first temperatures in the above embodiment; the operating powers of 100W and 105W are the second temperatures in the above embodiment.

[0088] Based on the above power correction formula, the corresponding fitting formula when the ambient temperature is 30°C can be obtained:

[0089] 95=100 / K+P 常

[0090] K = (30-R) / (25-R)

[0091] Based on the above power correction formula, the corresponding fitting formula when the ambient temperature is 35°C can be obtained:

[0092] 95=105 / K+P 常

[0093] K = (35-R) / (25-R)

[0094] According to the two fitting formulas, the power adjustment constant P can be obtained 常 =0, temperature adjustment constant R=-70. Optionally, it can also be calculated that the power adjustment coefficient K is 1.05 when the ambient temperature is 30°C; and the power adjustment coefficient K is 1.11 when the ambient temperature is 35°C.

[0095] When the two test samples of this refrigerator, i.e., the second refrigeration equipment, enter the commodity inspection line, the test samples are operated and the ambient temperature of the commodity inspection room is detected, i.e., the second temperature in the above embodiment is 28°C. The measured power of the two samples is obtained, i.e., the third power in the above embodiment is 104W and 102W respectively. Based on the power adjustment constant P 常 =0, temperature adjustment constant R = -70 and second temperature, the power adjustment coefficient K of one of the prototypes can be calculated to be 1.03, and the corrected third power P 修 =104 / 1.03=101W, and the refrigerant filling is judged to be unqualified. The power adjustment coefficient K of another prototype is calculated to be 1.03, and the corrected third power P is obtained. 修 =102 / 1.03=99W, the refrigerant filling is judged to be qualified.

[0096] In this embodiment, by fitting the operating power of the refrigerator under different environments, the correction parameters for correcting the refrigerator are determined. When the ambient temperature changes, the detected refrigerator power is corrected by the correction parameters, and the corrected power P is used. 修 To determine whether the refrigerant is filled properly, it can effectively avoid misjudgment of commodity inspection due to temperature fluctuations, and achieve the effect of accurately judging whether the refrigerator refrigerant is filled properly.

[0097] Based on the same inventive concept, the embodiment of the present application also provides a refrigerant detection device for implementing the refrigerant detection method involved above.
