[0053] It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative labor should fall within the scope of protection of the present application.

[0054] The present application provides a unit fluorine deficiency control method, referring to Figure 1 , Figure 1 The present application provides a unit fluorine deficiency control method, referring to

[0055] Step S10, obtaining unit operation data of the unit;

[0056] The unit is the object of the unit fluorine deficiency control; the unit can be specifically a multi-connected unit.

[0057] The unit operation data is the operation data related to the refrigerant in the unit; the specific data type in the unit operation data can be set based on actual needs, such as compressor operating frequency, high-pressure side pressure, compressor discharge temperature, outdoor electronic expansion valve opening, indoor pipe temperature, indoor electronic expansion valve opening, etc.

[0058] The acquisition of the unit operation data can be obtained based on the type of specific data and the related monitoring device, such as the high-pressure side pressure which can be obtained by setting a pressure sensor on the high-pressure side; the compressor discharge temperature can be obtained by setting a temperature sensor on the compressor discharge port; other types of data can be analogized to achieve, and will not be described here.

[0059] Step S20, determining whether the unit has a fluorine deficiency condition according to the unit operation data;

[0060] It can be understood that when the unit has a fluorine deficiency condition, part of the devices will be affected by the fluorine deficiency condition, resulting in abnormal characteristics of the corresponding data; for example, when the fluorine deficiency condition occurs, it will cause the total amount of refrigerant in the unit to be insufficient, thereby causing the refrigerant in the high-pressure side to be insufficient, the high-pressure side pressure to decrease, and at the same time, due to the unchanged work of the compressor, the discharge temperature to increase.

[0061] Therefore, the unit operation data can reflect whether the unit has a fluorine deficiency condition; the correlation between the specific unit operation data and the fluorine deficiency condition can be set based on the actual operation characteristics of the unit.

[0062] Step S30, if the unit has a fluorine deficiency condition, continuously monitoring the fluorine deficiency duration;

[0063] If the unit does not exist in the under-fluorine condition, the subsequent operation is not performed.

[0064] The under-fluorine duration is the duration of the under-fluorine condition existing in the unit; it can be understood that the longer the under-fluorine duration, the longer the unit runs in the under-fluorine condition, and the greater the possibility of the under-fluorine causing impact or failure to the unit; therefore, the under-fluorine duration is monitored in this embodiment to determine the degree of impact of the under-fluorine condition on the unit. Specifically, the under-fluorine identifier is set to be effective when the unit exists in the under-fluorine condition, and the under-fluorine duration is obtained by counting the effective duration of the under-fluorine identifier.

[0065] Step S40, determining a lack-fluorine level corresponding to the under-fluorine duration, wherein the under-fluorine duration is positively correlated with the lack-fluorine level;

[0066] The longer the under-fluorine duration, the greater the possibility of the under-fluorine causing impact or failure to the unit; therefore, in this embodiment, the lack-fluorine level is set to be positively correlated with the under-fluorine duration, so that the current lack-fluorine level of the unit can be accurately determined through the under-fluorine duration.

[0067] The lack-fluorine level can be set based on actual needs, such as the lack-fluorine level can be set to include a non-lack-fluorine level, a slight lack-fluorine level, a moderate lack-fluorine level, and a severe lack-fluorine level.

[0068] Step S50, performing a target processing strategy corresponding to the lack-fluorine level.

[0069] After determining the lack-fluorine level, a specific processing strategy can be performed for the lack-fluorine level.

[0070] The target processing strategy is a processing strategy determined based on the lack-fluorine level and needed to be performed on the unit.

[0071] Specifically, a corresponding processing strategy can be set for each lack-fluorine level in advance, and after the lack-fluorine level is determined, the corresponding target processing strategy can be matched.

[0072] This embodiment determines the under-fluorine condition of the unit through the unit operation data, and determines the lack-fluorine level of the current unit based on the under-fluorine duration of the under-fluorine condition, thereby determining the lack-fluorine condition of the current unit, and then performing a corresponding target processing strategy based on the lack-fluorine level, so that the unit failure caused by lack-fluorine can be avoided.

[0073] Further, referring to Figure 2 In the second embodiment of the unit lack-fluorine control method of the present application based on the first embodiment of the present application, the step S20 includes the steps of:

[0074] Step S21, determining a plurality of sub-data in the unit operation data;

[0075] In step S22, for each of the sub-data, an under-flu condition corresponding to the sub-data is obtained.

[0076] In step S23, it is judged whether the sub-data satisfies the corresponding under-flu condition.

[0077] In step S24, if each of the sub-data satisfies the under-flu condition, it is determined that the unit exists under-flu condition.

[0078] The sub-data is the data corresponding to a specific data type in the unit operation data; for example, the sub-data includes high-pressure side pressure, compressor discharge temperature, outdoor electronic expansion valve opening, indoor pipe temperature, and indoor electronic expansion valve opening.

[0079] The under-flu condition is a parameter feature indicating that the sub-data is in an under-flu condition; it can be understood that different types of sub-data have different expressions in the under-flu condition, and therefore, different under-flu conditions need to be set for different sub-data; for example:

[0080] The sub-data is high-pressure side pressure, and the corresponding set under-flu condition is high-pressure side pressure threshold; since under the under-flu condition, the high-pressure side pressure will decrease, and therefore, the set under-flu condition is that the high-pressure side pressure is less than the high-pressure side pressure threshold; the specific value of the high-pressure side pressure threshold can be set based on the actual needs of the unit, such as obtaining the high-pressure side pressure threshold by actually detecting the high-pressure side pressure of the under-flu and non-under-flu critical points;

[0081] The sub-data is the compressor discharge temperature, and the corresponding set under-flu condition is the compressor discharge temperature threshold; since under the under-flu condition, the compressor discharge temperature will increase, and therefore, the set under-flu condition is that the compressor discharge temperature is greater than the compressor discharge temperature threshold; the specific value of the compressor discharge temperature threshold can be set based on the actual needs of the unit, such as obtaining the compressor discharge temperature threshold by actually detecting the compressor discharge temperature of the under-flu and non-under-flu critical points;

[0082] The sub-data is the outdoor electronic expansion valve opening, and the corresponding set under-flu condition is the outdoor electronic expansion valve opening threshold; since under the under-flu condition, the superheat degree at the evaporator outlet increases, thereby causing the controller to increase the opening of the outdoor electronic expansion valve, and therefore, the set under-flu condition is that the outdoor electronic expansion valve opening is greater than the outdoor electronic expansion valve opening threshold; the specific value of the outdoor electronic expansion valve opening threshold can be set based on the actual needs of the unit, such as obtaining the outdoor electronic expansion valve opening threshold by actually detecting the outdoor electronic expansion valve opening of the under-flu and non-under-flu critical points;

[0083] When the sub-data is the indoor unit pipe temperature, the corresponding set undersized condition is an indoor unit pipe temperature threshold value. Since in the undersized condition, the refrigerant is insufficient, the indoor unit evaporation ends early, which causes the indoor unit pipe temperature to rise. Therefore, the set undersized condition is that the indoor unit pipe temperature is greater than the indoor unit pipe temperature threshold value. The specific value of the indoor unit pipe temperature threshold value can be set based on the actual needs of the unit, such as obtaining the indoor unit pipe temperature threshold value by actually detecting the indoor unit pipe temperatures of the undersized and non-undersized critical points.

[0084] When the sub-data is the indoor unit electronic expansion valve opening degree, the corresponding set undersized condition is an indoor unit electronic expansion valve opening degree threshold value. Since in the undersized condition, the indoor unit electronic expansion valve opening degree increases, the set undersized condition is that the indoor unit electronic expansion valve opening degree is greater than the indoor unit electronic expansion valve opening degree threshold value. The specific value of the indoor unit electronic expansion valve opening degree threshold value can be set based on the actual needs of the unit, such as obtaining the indoor unit electronic expansion valve opening degree threshold value by actually detecting the indoor unit electronic expansion valve opening degrees of the undersized and non-undersized critical points.

[0085] In this embodiment, multiple sub-data are set, so that the undersized condition can be comprehensively judged in combination with the running conditions of different devices in the unit, and the accuracy of undersized condition detection can be improved.

[0086] When the sub-data meets the respective corresponding undersized condition, it can be determined that the unit has an undersized condition.

[0087] Further, the step S23 includes the steps of:

[0088] Step S231: Obtain the parameter condition in the undersized condition and the time threshold value;

[0089] Step S232: Determine whether the sub-data meets the parameter condition, and the duration of meeting the parameter condition reaches the time threshold value;

[0090] Step S233: If the sub-data meets the parameter condition, and the duration of meeting the parameter condition reaches the time threshold value, it is determined that the sub-data meets the corresponding undersized condition.

[0091] In actual application, the running data of the unit fluctuates, so it is possible that part or all of the sub-data meet the corresponding undersized condition in the case that the unit does not have an undersized condition. Therefore, in order to avoid the occurrence of false identification of undersized, in this embodiment, the parameter condition and the time threshold value are specifically set in the undersized condition.

[0092] The parameter condition is a condition for specifically evaluating the sub-data. For example, if the sub-data is the high-pressure side pressure, the corresponding set parameter condition is that the high-pressure side pressure is less than a high-pressure side pressure threshold value; if the sub-data is the compressor discharge temperature, the corresponding set parameter condition is that the compressor discharge temperature is greater than a compressor discharge temperature threshold value; if the sub-data is the outdoor electronic expansion valve opening degree, the corresponding set parameter condition is that the outdoor electronic expansion valve opening degree is greater than an outdoor electronic expansion valve opening degree threshold value; if the sub-data is the indoor unit pipe temperature, the corresponding set parameter condition is that the indoor unit pipe temperature is greater than an indoor unit pipe temperature threshold value; and if the sub-data is the indoor electronic expansion valve opening degree, the corresponding set parameter condition is that the indoor electronic expansion valve opening degree is greater than an indoor electronic expansion valve opening degree threshold value.

[0093] The time length threshold value is a condition for the duration of the sub-data meeting the parameter condition. When the duration of the sub-data meeting the parameter condition reaches the corresponding time length threshold value, it is considered that the sub-data is stably in the under-fluorine condition, and therefore, it can be determined that the sub-data meets the parameter condition due to the influence of the under-fluorine. At this time, it is considered that the sub-data meets the under-fluorine condition, and the influence of accidental factors is excluded.

[0094] The time length threshold values corresponding to different sub-data can be set to be different, and the specific time length threshold values can be set based on actual needs.

[0095] In this embodiment, by specifically setting the parameter condition and the time length threshold value in the under-fluorine condition, it can be avoided that the sub-data fluctuation caused by accidental factors, and the accuracy of the under-fluorine condition determination is ensured.

[0096] Further, the step S24 includes the steps of:

[0097] Step S241, determining the under-fluorine quantity of the sub-data meeting the corresponding under-fluorine condition;

[0098] Step S242, judging whether the under-fluorine quantity reaches a preset quantity threshold value;

[0099] Step S243, if the under-fluorine quantity reaches the preset quantity threshold value, determining that the unit exists the under-fluorine condition.

[0100] The under-fluorine quantity is the quantity of the sub-data meeting the under-fluorine condition.

[0101] In actual application, the operation data of the unit is also affected by other aspects besides the under-fluorine, therefore, when the unit appears the under-fluorine condition, not all sub-data can meet the corresponding under-fluorine condition; therefore, in order to improve the determination accuracy of the under-fluorine condition, in the embodiment, it is not required that all sub-data meet the under-fluorine condition to consider that the unit exists the under-fluorine condition; the embodiment specifically sets a preset number threshold; the specific value of the preset number threshold can be set based on actual needs, such as based on the type number of the sub-data, such as the number of the sub-data is 5, the preset number threshold can be set to be greater than the general type number of the sub-data, such as 3.

[0102] When the under-fluorine number reaches the preset number threshold, it is considered that the number of the sub-data meeting the under-fluorine condition is relatively large, the devices affected by the under-fluorine in the unit are relatively large, and the possibility of the unit existing the under-fluorine condition is relatively high, therefore, it is determined that the unit exists the under-fluorine condition.

[0103] If the under-fluorine number is less than the preset number threshold, it is considered that the number of the sub-data meeting the under-fluorine condition is relatively small, the devices affected by the under-fluorine in the unit are relatively small, and the possibility of the unit existing the under-fluorine condition is relatively low, therefore, it is determined that the unit does not exist the under-fluorine condition.

[0104] In the embodiment, the preset number threshold is set to determine whether the unit exists the under-fluorine condition based on the number of the sub-data meeting the under-fluorine condition, so that the misjudgment caused by other parameters in the unit can be avoided, and the accuracy of the under-fluorine condition determination is ensured.

[0105] Further, referring to Figure 3 In the third embodiment of the unit under-fluorine control method of the application based on the first embodiment of the application, the step S40 comprises the steps of:

[0106] Step S41, obtaining the running duration of the unit;

[0107] Step S42, calculating the under-fluorine proportion of the under-fluorine duration in the running duration;

[0108] Step S43, determining the under-fluorine level corresponding to the under-fluorine proportion.

[0109] The running duration is the duration of the continuous operation of the unit; when the compressor is closed, the under-fluorine control method in the application is not executed, when the compressor starts to operate, the timing is started, and the running duration of the unit is updated in real time.

[0110] The fluorine deficiency proportion indicates a proportion of the under-fluorine condition in the operation of the unit; it can be understood that, in the same time, the greater the fluorine deficiency proportion, the earlier the under-fluorine condition of the unit occurs; and in the same fluorine deficiency proportion, the shorter the operation time, the earlier the under-fluorine condition of the unit occurs; therefore, the specific fluorine deficiency level is determined based on the fluorine deficiency proportion in this embodiment, so that the overall situation of the under-fluorine condition in the operation of the unit can be determined, and the accuracy of the determination of the fluorine deficiency level is improved.

[0111] Further, the step S43 comprises the steps of:

[0112] Step S431, matching a target proportion interval corresponding to the fluorine deficiency proportion;

[0113] Step S432, determining an associated level corresponding to the target proportion interval, wherein the value corresponding to the target proportion interval is positively correlated with the severity of the associated level;

[0114] Step S433, taking the associated level as the fluorine deficiency level corresponding to the fluorine deficiency proportion.

[0115] The target proportion interval is a proportion interval corresponding to the fluorine deficiency proportion; a plurality of proportion intervals can be set based on the actual needs of the unit in advance, such as setting four proportion intervals (0, A) (A, B) (B, C) (C, 1), wherein A < B < C; it should be noted that the above four proportion intervals are only for illustration, and more or fewer proportion intervals can be set based on the actual application needs in actual application. At the same time, different proportion intervals are associated with corresponding associated levels, and the value corresponding to the target proportion interval is positively correlated with the severity of the associated level, such as (0, A) corresponding to a non-fluorine deficiency level; (A, B) corresponding to a slight fluorine deficiency level; (B, C) corresponding to a moderate fluorine deficiency level; (C, 1) corresponding to a serious fluorine deficiency level.

[0116] After the fluorine deficiency proportion is determined, the proportion interval in which the fluorine deficiency proportion is located, i.e. the target proportion interval, is determined according to the specific value of the fluorine deficiency proportion, and then the associated level corresponding to the target proportion interval is determined, so as to obtain the corresponding fluorine deficiency level; for example, if the proportion interval in which the fluorine deficiency proportion is located is (B, C), the corresponding fluorine deficiency level is a moderate fluorine deficiency level.

[0117] In this embodiment, the fluorine deficiency level is matched through the proportion interval, so that the fluorine deficiency level of the unit can be accurately determined.

[0118] Further, referring to Figure 4 In the fourth embodiment of the unit fluorine deficiency control method of the present application based on the first embodiment of the present application, the step S50 comprises the steps of:

[0119] Step S51, determining whether the fluorine deficiency level is a serious fluorine deficiency level;

[0120] In step S52, if the fluorine deficiency level is the serious fluorine deficiency level, the control unit controls the air conditioner to stop running.

[0121] When the fluorine deficiency level is the serious fluorine deficiency level, it is considered that the amount of refrigerant in the air conditioner is too low, and the air conditioner will be malfunctioned or damaged if it continues to run. Therefore, the air conditioner is controlled to stop running at this time, so that the malfunction of the air conditioner is avoided.

[0122] Different processing strategies can be set for different fluorine deficiency levels. For example:

[0123] When the fluorine deficiency level is the non-fluorine deficiency level, there is no fluorine deficiency condition under this level, and the corresponding processing strategy is to maintain normal running of the air conditioner.

[0124] When the fluorine deficiency level is the slight fluorine deficiency level, there is a weak fluorine deficiency condition under this level, but it will not affect the running of the air conditioner. Therefore, the corresponding processing strategy is to maintain normal running of the air conditioner.

[0125] When the fluorine deficiency level is the moderate fluorine deficiency level, there is a certain fluorine deficiency condition under this level, but it will not cause malfunction or damage to the running of the air conditioner. Therefore, the corresponding processing strategy is to maintain normal running of the air conditioner while abnormally reminding the fluorine deficiency condition of the air conditioner to remind the user to supplement the refrigerant in time.

[0126] When the fluorine deficiency level is the serious fluorine deficiency level, there is a serious fluorine deficiency condition under this level, which will affect the running of the air conditioner. Therefore, the corresponding processing strategy is to control the air conditioner to stop running, and a fluorine deficiency protection reminder can also be given to remind the user to handle the fluorine deficiency condition in time.

[0127] It should be noted that the setting relationship between the above-mentioned fluorine deficiency levels and the corresponding processing strategies is for illustration, and the processing strategies corresponding to different fluorine deficiency levels can also be set based on actual needs.

[0128] In the embodiment, the air conditioner is controlled to stop running when the serious fluorine deficiency level is detected, so that malfunction and damage of the air conditioner in the case of serious fluorine deficiency can be avoided.

[0129] It should be noted that, for the above-mentioned method embodiments, in order to simply describe, they are all expressed as a series of action combinations, but those skilled in the art should know that the present application is not limited by the action sequence described, because according to the present application, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should know that the embodiments described in the specification all belong to preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0130] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be realized by means of software on a general hardware platform as necessary, and of course can also be realized by hardware, but in many cases the former is a better embodiment. Based on such understanding, the technical solutions of the present application can be embodied in the form of a software product in essence or the part that contributes to the prior art, and the computer software product is stored in a storage medium (such as a ROM / RAM, a magnetic disk, or an optical disc), and includes a plurality of instructions for causing a terminal device (which can be a mobile phone, a computer, a server, or a network device) to execute the method described in each embodiment of the present application.
