[0025] The present disclosure will be further described in details by the following embodiments in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments provided herein are only used to explain the present disclosure, and are not used to limit the present disclosure. In addition, the embodiments provided below are used to implement part of the present disclosure, and the technical solutions described in the embodiments of the present disclosure can be implemented in any combination manner without conflict.

[0026] It should be noted that in the embodiments of the present disclosure, the terms “comprise”, “contain” or any other variants thereof are intended to cover non-exclusive inclusion, so that the method or device comprising a series of elements not only includes the elements explicitly described, but also includes other elements not explicitly listed, or includes elements inherent in the implementation of the method or device. Without more limitation, the element defined by the sentence “comprises a…” does not exclude the presence of other related elements (such as steps in the method or units in the device, for example, the unit can be part of the circuit, part of the processor, part of the program or software, etc.) in the method or device comprising the element.

[0027] For example, the jet augment control method provided by the embodiments of the present disclosure includes a series of steps, but the jet augment control method provided by the embodiments of the present disclosure is not limited to the steps described, and similarly, the jet augment control device provided by the embodiments of the present disclosure includes a series of units, but the device provided by the embodiments of the present disclosure is not limited to including the units explicitly described, and can also include units that need to be set when obtaining relevant information or processing based on information.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. The terminology used in the specification herein is for describing specific embodiments only and is not intended to be limiting of the present disclosure.

[0029] It can be understood that in the specific embodiments of the present application, relevant data is involved, and when the embodiments in the present application are applied to specific products or technologies, the permission or consent of the user needs to be obtained, and the collection, use and processing of relevant data need to comply with relevant laws, regulations and standards in relevant countries and regions.

[0030] Figure 1 A flowchart of a jet augment control method according to an embodiment of the present application is schematically shown. The execution subject of the jet augment control method can be any control device with processing capability, for example, an air conditioner, a mobile phone, a computer, a smart watch and other household appliances, etc. In a specific embodiment of the present application, the control device as the execution subject of the jet augment control method is specifically an air conditioner itself, and the air conditioner specifically controls the jet augment through its control module.

[0031] Jet augment: The jet augment technology mainly realizes the augment effect by introducing medium-pressure refrigerant into the compressor through an additional auxiliary air supplement port for supplement. Specifically, the technology separates the part of medium-pressure refrigerant through a flash evaporator or an economizer, and supplements the refrigerant into the working chamber of the compressor through the auxiliary air supplement port for supplement. In this process, the medium-low pressure is compressed while jetting and mixing cooling, and then the high pressure is normally compressed, which improves the compressor discharge capacity and further improves the heating capacity in a low-temperature environment. However, if the flow rate of the refrigerant supplemented into the working chamber of the compressor (hereinafter uniformly referred to as the air supplement flow rate) is not appropriate, the air supplement to the compressor will not be stable enough, resulting in poor low-temperature heating stability of the air conditioner.

[0032] The jet augment control method of the embodiments of the present application can control the appropriate air supplement flow rate supplemented into the working chamber of the compressor, ensure that the air supplement amount of the unit is always at an appropriate and stable air supplement flow rate, ensure the long-term operation reliability of low-temperature heating, and improve the low-temperature heating stability of the air conditioner.

[0033] Specifically, as shown in FIG. 1, the jet augment control method provided by the embodiments of the present application includes the following steps. Figure 1As shown, the jet augmenting control method of the embodiment of the present application can include steps S110 to S140.

[0034] In step S110, the temperature of the inner tube of the evaporator is monitored, and the temperature of the inner tube of the evaporator monitored in a predetermined time interval is averaged to obtain an average temperature of the inner tube of the evaporator in the predetermined time interval.

[0035] In step S120, if the average temperature of the inner tube of the evaporator is within a predetermined range, the air supplementing flow rate of the jet augmenting is maintained as the initial flow rate.

[0036] In step S130, if the average temperature of the inner tube of the evaporator is less than the predetermined range, the air supplementing flow rate is gradually increased until the average temperature of the inner tube of the evaporator monitored after the air supplementing flow rate is increased is within the predetermined range.

[0037] In step S140, if the average temperature of the inner tube of the evaporator is greater than the predetermined range, the air supplementing flow rate is gradually decreased until the average temperature of the inner tube of the evaporator monitored after the air supplementing flow rate is decreased is within the predetermined range.

[0038] After the air conditioner is turned on, the air supplementing flow rate of the air supplementing control for the working chamber of the compressor can be set as the initial flow rate L. The temperature of the inner tube of the evaporator of the indoor unit of the air conditioner can be continuously monitored, and the temperature of the inner tube of the evaporator monitored in a predetermined time interval can be averaged to obtain an average temperature of the inner tube of the evaporator in the predetermined time interval.

[0039] During the heating operation of the air conditioner, if the average temperature of the inner tube of the evaporator monitored is within a predetermined range (a to b), the air supplementing flow rate of the jet augmenting is maintained as the initial flow rate L. That is, if the average temperature of the inner tube of the evaporator a≤ΔT≤b, the air supplementing flow rate is maintained as the initial flow rate L.

[0040] If the average temperature of the inner tube of the evaporator monitored is less than the predetermined range (i.e., ΔT

[0041] If the average temperature of the inner tube of the evaporator monitored is greater than the predetermined range (i.e., ΔT

[0042] It can be understood that after the air supplementing flow rate of the jet augmenting is maintained as the initial flow rate L or the LC, the jet augmenting control can be continuously performed according to the foregoing steps.

[0043] With the jet augment control mode of the embodiments of the application, the appropriate supplementary air flow rate can be reliably controlled continuously, the supplementary air amount of the unit is ensured to be always at an appropriate stable supplementary air flow rate, the long-term operation reliability of low-temperature heating is ensured, the low-temperature heating stability of the air conditioner is improved, and the user experience is improved.

[0044] The following describes Figure 1 When the jet augment control is performed in the embodiments, further optional specific embodiments of each step are described.

[0045] In an embodiment, the monitoring of the evaporator inner tube temperature can include: obtaining sensing data of a temperature sensor arranged at the evaporator inner tube; and obtaining the evaporator inner tube temperature according to the sensing data. The temperature sensor is arranged at the evaporator inner tube, the sensing data is obtained by sensing the evaporator inner tube, and the evaporator inner tube temperature is obtained in real time according to the sensing data.

[0046] Further, in an embodiment, the monitoring of the evaporator inner tube temperature can include: monitoring the suction pressure of the suction port of the compressor by a pressure sensor; and obtaining the evaporator inner tube temperature by conversion processing according to the suction pressure.

[0047] In this embodiment, the suction pressure of the suction port of the compressor is monitored in real time by the pressure sensor, and then the suction pressure is converted and processed, and the evaporator inner tube temperature is obtained by reverse conversion of the suction pressure of the compressor. The evaporator inner tube temperature takes into account the suction condition of the compressor, and the evaporator inner tube temperature is used in the steps of the embodiments of the application, which can further ensure that the supplementary air amount of the unit is always at an appropriate stable supplementary air flow rate, thereby further effectively improving the low-temperature heating stability of the air conditioner.

[0048] Further, in an embodiment, the monitoring of the evaporator inner tube temperature can include: obtaining sensing data of a temperature sensor arranged at the evaporator inner tube, obtaining a first temperature according to the sensing data; monitoring the suction pressure of the suction port of the compressor by a pressure sensor, and obtaining a second temperature by conversion according to the suction pressure; and taking the average of the first temperature and the second temperature as the evaporator inner tube temperature. In this way, the supplementary air amount of the unit can be further ensured to be always at an appropriate stable supplementary air flow rate, thereby further effectively improving the low-temperature heating stability of the air conditioner.

[0049] In an embodiment, refer to Figure 2, the step of gradually increasing the make-up gas flow until the average value of the monitored tube temperature is within the predetermined range comprises: step S210, increasing the make-up gas flow from an initial flow by a first value to obtain a first flow; and monitoring a first average value of the tube temperature in the evaporator within a predetermined time period after the increase to the first flow; step S220, if the first average value is less than the predetermined range, increasing the make-up gas flow from the first flow by the first value to obtain a second flow; step S230, monitoring a second average value of the tube temperature in the evaporator within a predetermined time period after the increase to the second flow; and step S240, adjusting the make-up gas flow according to the first average value, the second average value and the predetermined range until the average value of the monitored tube temperature is within the predetermined range.

[0050] Specifically, after the air conditioner is turned on, the make-up gas flow for the compressor working cavity in the jet augmenting enthalpy control can be set as an initial flow L. When the average value of the tube temperature is less than the predetermined range (i.e., ΔT

[0051] If the first average value ΔT1 is less than the predetermined range (i.e., ΔT1

[0052] The make-up gas flow is further adjusted according to the first average value ΔT1, the second average value ΔT2 and the predetermined range (a to b) until the average value of the monitored tube temperature is within the predetermined range. In the case where the average value of the tube temperature is less than the predetermined range, the make-up gas flow can be smoothly controlled.

[0053] Further, the step of adjusting the make-up gas flow according to the first average value, the second average value and the predetermined range until the average value of the monitored tube temperature is within the predetermined range can specifically comprise:

[0054] If the second average value is less than the predetermined range and the second average value is greater than the first average value, a slow start phase is entered until the average value of the monitored tube temperature is within the predetermined range, wherein the make-up gas is turned on every predetermined time period and the make-up gas flow is the second flow in the slow start phase.

[0055] If the second average value is less than the predetermined range and the second average value is less than or equal to the first average value, the air supplementing flow rate is gradually increased until the monitored average value of the tube temperature is within the predetermined range after the air supplementing flow rate is increased.

[0056] If the second average value is within the predetermined range, the air supplementing flow rate controlled by the jet energy increasing is maintained as the second flow rate.

[0057] If the second average value is less than the predetermined range (i.e., ΔT2

[0058] If the second average value is less than the predetermined range (i.e., ΔT2

[0059] If the second average value is within the predetermined range (i.e., a≤ΔT2≤b), the air supplementing flow rate controlled by the jet energy increasing is maintained as the second flow rate L2, that is, the smooth air supplementing can be realized.

[0060] In this embodiment, the different situations of the first average value ΔT1, the second average value ΔT2 and the predetermined range (a to b) can be effectively considered, and the corresponding air supplementing control means is executed according to the different situations, so that the smooth control of the air supplementing flow rate can be reliably realized.

[0061] In an embodiment, referring to Figure 3 The gradually reducing the air supplementing flow rate until the monitored average value of the tube temperature is within the predetermined range after the air supplementing flow rate is reduced can include:

[0062] In step S310, the air supplementing flow rate is reduced by a second value from an initial flow rate to obtain a third flow rate, and a third average value of the tube temperature in the evaporator within a predetermined time period after the air supplementing flow rate is reduced to the third flow rate is monitored; in step S320, if the third average value is greater than the predetermined range, the air supplementing flow rate is reduced by the second value from the third flow rate to obtain a fourth flow rate; in step S330, a fourth average value of the tube temperature in the evaporator within a predetermined time period after the air supplementing flow rate is reduced to the fourth flow rate is monitored; and in step S340, the air supplementing flow rate is adjusted according to the third average value, the fourth average value and the predetermined range until the monitored average value of the tube temperature is within the predetermined range.

[0063] Specifically, after the air conditioner is turned on, the air injection flow rate for supplementing the working chamber of the compressor in the air injection enthalpy-increasing control can be set as an initial flow rate L. When the average value of the tube temperature is greater than the predetermined range (i.e., ΔT > a) in a certain monitoring, the air injection flow rate is reduced by a second value (which can be the same as or different from the first value in the foregoing embodiment) from the initial flow rate L to obtain a third flow rate L3; after being reduced to the third flow rate L3, the tube temperature in the evaporator is monitored for a predetermined time period, and the average value ΔT3 of the tube temperature in the evaporator in the predetermined time period after being reduced to the third flow rate L3 is obtained.

[0064] If the third average value ΔT3 is greater than the predetermined range (i.e., ΔT3 > a), the air injection flow rate is reduced by the second value from the third flow rate L3, so that the air injection flow rate is reduced to a fourth flow rate L4. After being reduced to the fourth flow rate L4, the tube temperature in the evaporator is monitored for a predetermined time period, and the fourth average value ΔT4 of the tube temperature in the evaporator in the predetermined time period after being reduced to the fourth flow rate L4 is obtained.

[0065] The air injection flow rate is further adjusted according to the third average value ΔT3, the fourth average value ΔT4, and the predetermined range (a to b) until the average value of the monitored tube temperature is within the predetermined range. In the case where the average value of the tube temperature is greater than the predetermined range, the air injection flow rate can be smoothly controlled reliably.

[0066] Further, the adjustment of the air injection flow rate according to the third average value, the fourth average value, and the predetermined range until the average value of the monitored tube temperature is within the predetermined range can specifically include:

[0067] If the fourth average value is greater than the predetermined range and the fourth average value is greater than the third average value, the air injection flow rate is gradually reduced until the average value of the monitored tube temperature is within the predetermined range after the air injection flow rate is reduced;

[0068] If the fourth average value is greater than the predetermined range and the fourth average value is less than or equal to the third average value, a slow closing stage is entered until the average value of the monitored tube temperature is within the predetermined range, wherein the air injection flow rate in the slow closing stage is the second flow rate and the air injection is closed every predetermined time period.

[0069] If the fourth average value is within the predetermined range, the air injection flow rate of the air injection enthalpy-increasing control is maintained at the fourth flow rate.

[0070] If the fourth average value is greater than the predetermined range (i.e., ΔT4 > b) and the fourth average value is greater than the third average value (i.e., ΔT4 > ΔT3), the foregoing step of gradually reducing the air injection flow rate until the average value of the monitored tube temperature is within the predetermined range after the air injection flow rate is reduced is continuously repeated.

[0071] If the fourth average value is greater than the predetermined range (i.e., AT4 > b) and the fourth average value is less than or equal to the third average value (i.e., AT4 < AT3), a slow closing stage is entered, in which the makeup gas flow control is maintained at the second flow rate and the makeup gas is closed every predetermined time interval until the monitored average value of the tube temperature is within the predetermined range, the slow closing stage is ended, and the makeup gas flow is maintained at the second flow rate for continuous makeup gas.

[0072] If the fourth average value is within the predetermined range (i.e., a < AT4 < b), the makeup gas flow of the jet enhanced heating is controlled to maintain the fourth flow rate L4, that is, the stable makeup gas can be achieved.

[0073] In this embodiment, the third average value AT3, the fourth average value AT4, and the different cases of the predetermined range (a to b) can be effectively considered, and the corresponding makeup gas control means can be performed according to different cases, so that the stable control of the makeup gas flow can be reliably performed.

[0074] In addition, the application also provides a jet enhanced heating control device, which can be applied to a control equipment. Figure 4 As shown in Figure 4 A block diagram of a jet enhanced heating control device according to an embodiment of the application is shown, in particular: the jet enhanced heating control device 400 can include a processor 401 having one or more processing cores, a memory 402 having one or more computer readable storage media.

[0075] The processor 401 can load the executable file corresponding to the process of one or more computer programs into the memory 402 according to the instructions, and run the computer program stored in the memory 402 by the processor 401, so as to realize various functions in the embodiments of the foregoing jet enhanced heating control method of the application.

[0076] The processor 401 can perform the following steps:

[0077] The tube temperature in the evaporator is monitored, and every predetermined time interval, the tube temperature in the evaporator monitored in the predetermined time interval is averaged to obtain an average value of the tube temperature in the predetermined time interval; if the average value of the tube temperature is within the predetermined range, the makeup gas flow of the jet enhanced heating is controlled to maintain the initial flow rate; if the average value of the tube temperature is less than the predetermined range, the makeup gas flow is gradually increased until the average value of the tube temperature monitored after the makeup gas flow is increased is within the predetermined range; if the average value of the tube temperature is greater than the predetermined range, the makeup gas flow is gradually reduced until the average value of the tube temperature monitored after the makeup gas flow is reduced is within the predetermined range.

[0078] In one embodiment, the gradually increasing the supplemental gas flow rate until the monitored average tube temperature is within the predetermined range comprises: increasing the supplemental gas flow rate from an initial flow rate by a first value to obtain a first flow rate; monitoring a first average tube temperature in the evaporator over a predetermined time period after the increase to the first flow rate; if the first average tube temperature is less than the predetermined range, increasing the supplemental gas flow rate from the first flow rate by the first value to obtain a second flow rate; monitoring a second average tube temperature in the evaporator over the predetermined time period after the increase to the second flow rate; and adjusting the supplemental gas flow rate based on the first average tube temperature, the second average tube temperature, and the predetermined range until the monitored average tube temperature is within the predetermined range.
