Description

[0002] Currently, cold storage air conditioners are widely used in daily life. The cold storage unit of a cold storage air conditioner is used to make ice, and when the cold storage air conditioner is cooling, it achieves cooling through the phase change of water to provide cooling capacity to the room.

[0003] In related technologies, the cold storage unit transforms liquid water into a solid state and stores it in an ice storage tank and a cold storage tank. A refrigerant-circulating heat exchanger in the cold storage tank exchanges heat with the refrigerant, releasing the cold energy into the indoor space through the heat release heat exchanger connected to the refrigerant-absorbing heat exchanger, thus achieving the cooling process. Users can then retrieve ice from the ice storage tank when needed. However, the ice storage capacity of the ice storage tank and the cold storage tank is limited. Inadequate ice storage planning not only increases the energy consumption of the cold storage air conditioner but also reduces the user experience. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a control method for a cold storage air conditioner, which can improve the rationality of ice storage planning, enhance the user experience, and reduce the energy consumption of the cold storage air conditioner.

[0005] This application further proposes a control device for an air conditioner.

[0006] This application also proposes a cold storage air conditioner.

[0007] This application further proposes a computer-readable storage medium.

[0008] According to the control method of the cold storage air conditioner according to the first aspect of this application, the cold storage air conditioner includes: a cold storage unit, an ice storage tank, a cold storage tank, and a cold release unit. The cold storage unit is used for ice making. The cold storage unit is connected to the ice storage tank to store ice for domestic use. The cold storage unit is connected to the cold storage tank to store ice for cold release. The cold release unit is connected to the cold storage tank to perform refrigeration. The control method includes: obtaining a first ice quantity m1 of the ice storage tank and a second ice quantity m2 of the cold storage tank; determining the working level of the cold storage unit in the cold storage mode according to the first ice quantity m1 and the second ice quantity m2; and making ice according to the target ice making speed va and ice making time t0 under the working level.

[0009] According to the control method of the cold storage air conditioner in the embodiments of this application, the cold storage unit can be controlled to make ice at an appropriate working level according to the amount of ice in the ice storage tank and the cold storage tank, so as to avoid the phenomenon of ice breakage in the cold storage tank and / or the ice storage tank, ensure that the amount of ice in the cold storage tank can achieve continuous and stable cooling, and that the ice in the ice storage tank can meet the needs of daily life and improve the user experience.

[0010] According to some embodiments of this application, determining the operating level of the cold storage unit based on the first ice quantity m1 and the second ice quantity m2, and making ice based on the operating level includes: determining a first ice-making speed v1 corresponding to the ice storage tank based on the first ice quantity m1, determining a second ice-making speed v2 corresponding to the cold storage tank based on the second ice quantity m2; and determining a target ice-making speed va under the operating level based on the first ice-making speed v1 and the second ice-making speed v2.

[0011] According to some embodiments of this application, the target ice-making speed va under the working position is determined based on the first ice-making speed v1 and the second ice-making speed v2 as follows: va = v1 + v2.

[0012] In some embodiments, the method further includes: obtaining the working duration t1 of the cold storage air conditioner in cooling mode; and making ice at the working setting during the working duration t1.

[0013] Further, making ice at the specified working speed during the working duration t1 includes: recording the amount of ice used for cooling n1 and the amount of ice used for domestic use n2 each time, as well as the corresponding time information; determining the ice consumption rate for cooling v3 and the ice consumption rate for domestic use v4; correcting the target ice-making speed va based on the ice consumption rate for cooling v3, the ice consumption rate for domestic use v4, and the working duration t1; and completing ice making at the corresponding target speed during the working duration t1 based on the corrected target ice-making speed.

[0014] Further, correcting the target ice-making speed va based on the cooling ice consumption rate v3, the domestic ice consumption rate v4, and the working time t1 includes: correcting the first ice-making speed v1 based on the cooling ice consumption rate v3 and the working time t1; correcting the second ice-making speed v2 based on the domestic ice consumption rate v4 and the working time t1; and obtaining the corrected target ice-making speed va based on the corrected first ice-making speed v1 and the second ice-making speed v2.

[0015] According to some embodiments of this application, the target ice-making speed va can be achieved by adjusting the fan speed and compressor frequency of the cold storage unit.

[0016] In some embodiments, determining the operating level of the cold storage unit in cold storage mode based on the first ice quantity m1 and the second ice quantity m2 includes: the first ice quantity m1 ≥ the first preset ice quantity and the second ice quantity m2 ≥ the second preset ice quantity, which is the first level; the first ice quantity m1 ≥ the first preset ice quantity and the second ice quantity m2 < the second preset ice quantity, which is the second level; the first ice quantity m1 < the first preset ice quantity and the second ice quantity m2 ≥ the second preset ice quantity, which is the third level; and the first ice quantity m1 < the first preset ice quantity and the second ice quantity m2 < the second preset ice quantity, which is the fourth level; wherein, the volume of the cold storage tank is larger than the volume of the ice storage tank.

[0017] Furthermore, the control method also includes: controlling the cold storage unit to selectively connect to the ice storage tank or the cold storage tank according to the first ice quantity m1 and the second ice quantity m2.

[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figure 1 As shown, the cold storage air conditioner 100 of this application includes: a cold storage unit 10, an ice storage tank 20, and a cooling unit 30. The cold storage unit 10 is used to make ice, that is, water (e.g., water or other media with high specific heat capacity) can change from phase to solid under the heat exchange of the cold storage unit 10. The ice storage tank 20 is used to store ice for domestic use after phase change. The cold storage tank 40 is used to store ice for cooling. The cooling unit 30 directly or indirectly exchanges heat with the ice for cooling in the cold storage tank 40 and releases cold to the indoor space after heat exchange to achieve cooling of the indoor space.

[0037] The cold storage unit 10 has a first ice outlet and a second ice outlet. The ice blocks obtained by the cold storage unit 10 can be discharged through the first ice outlet or the second ice outlet. The ice storage tank 20 is connected to the first ice outlet, and the cold storage tank 40 is connected to the second ice outlet. The ice storage tank 20 has an ice extraction port for taking ice blocks for daily use. The cold storage tank 40 is part of the cold release unit 30. The heat exchanger of the cold release unit 30 exchanges heat with the ice blocks in the cold storage tank 40 and discharges the cold energy into the room.

[0038] Specifically, the first ice outlet of the cold storage unit 10 is connected to the ice storage tank 20. The ice storage tank 20 is constructed as a semi-enclosed structure, and the ice outlet can be selectively connected to the outside world to facilitate the use of ice in daily life and enrich the functions of the cold storage air conditioner 100.

[0039] like Figure 1 As shown, according to some embodiments of this application, the cold storage unit 10 includes: a compressor 11, a first fan assembly 12, a first heat exchanger 13, a second heat exchanger 14, and an ice-making box 15. The compressor 11 is connected to the first heat exchanger 13 to make ice. The second heat exchanger 14 is disposed in the ice-making box 15. The ice-making box 15 has a first ice outlet and a second ice outlet. The first fan assembly 12 is used to dissipate heat from the second heat exchanger 14.

[0040] Specifically, the first heat exchanger 13, the compressor 11, and the second heat exchanger 14 are connected in sequence to define a refrigeration circuit. The second heat exchanger 14 is installed inside the ice box 15, which contains water to be converted to phase. The second heat exchanger 14 exchanges heat with the water in the ice box 15, and the high-temperature refrigerant after heat exchange flows to the first heat exchanger 13. The first heat exchanger 13 is directly opposite the first fan assembly 12. The first fan assembly 12 rotates to cool the refrigerant in the first heat exchanger 13. The cooled refrigerant flows back to the compressor 11 to complete the ice-making cycle. The ice blocks produced can be discharged from the ice box 15 through the first ice outlet and / or the second ice outlet.

[0041] The cold storage unit 10 of this application makes ice through a refrigeration circuit formed by the compressor 11, the first heat exchanger 13 and the second heat exchanger 14, which makes ice faster. The ice blocks made can be directly discharged into the ice storage tank 20 through the first ice outlet of the ice box 15, or directly discharged into the cold storage tank 40 through the second ice outlet, which improves the convenience of ice collection.

[0042] Understandably, the ice maker 15 can be equipped with multiple ice trays, each with the same geometric shape and a more reasonable ice cube size. This avoids users taking ice cubes that are too large or too small in daily life, meeting their needs and improving the user experience.

[0043] Ice guiding channels can be set between the first ice outlet and the ice storage tank 20, and between the second ice outlet and the cold storage tank 40. The ice blocks can be guided through the ice guiding channels to avoid jamming. Alternatively, the ice storage tank 20 can be set directly below the first ice outlet and the cold storage tank 40 can be set directly below the second ice outlet, so that they fall directly into the ice under the action of gravity, which can improve the convenience of ice removal.

[0044] It is understood that in some embodiments, the ice maker 15 is connected to the household water supply through a first valve and is equipped with a flow meter to close the first valve after the water volume in the ice maker 15 reaches a water volume threshold; in other embodiments, the cold storage air conditioner 100 may be equipped with a water tank with a large volume, which can store a certain amount of water.

[0045] In other words, during the preparation stage before the cold storage air conditioner 100 releases cold water, household water or water from the water tank can be added to the ice-making box 15. After the cold storage unit 10 completes ice making, it can then release or use the ice. Connecting the ice-making box 15 to the household water via the first valve means that the ice-making box 15 has a filling port, which is connected to the household water via a pipeline. A first valve is installed on the pipeline to control the selective connection between the household water and the filling port. A flow meter is used to record the amount of water added to avoid overfilling and overflow, thereby improving the operational stability of the cold storage air conditioner 100.

[0046] In an embodiment where the water tank and ice maker 15 can be optionally connected, the filling port is connected to the water tank via a pipeline, a first valve is installed on the pipeline, and a flow meter can also be installed on the pipeline to record the filling amount.

[0047] In this way, by setting the first valve, the operation of adding water into the ice box 15 is simpler and more convenient. By setting the flow meter, overfilling can be avoided, and the cold storage mechanism can be prevented from overflowing the ice box 15. This is to prevent water from causing a short circuit inside the cold storage air conditioner 100 and damaging the electrical components inside the cold storage air conditioner 100, thereby improving the working stability and safety of the cold storage air conditioner 100.

[0048] like Figure 1 As shown, according to some embodiments of this application, the cooling unit 30 includes: a circulating pump 31, a second fan assembly 32, a third heat exchanger 33, a fourth heat exchanger 34, and a cold storage tank 40. The third heat exchanger 33 is disposed in the cold storage tank 40, which has an ice inlet. The circulating pump 31 is connected to the third heat exchanger 33 so that the refrigerant after heat exchange in the third heat exchanger 33 flows to the fourth heat exchanger 34. The fourth heat exchanger 34 is directly opposite the second fan assembly 32, which generates airflow to cool the indoor space. In this way, cooling can be achieved through heat exchange between the refrigerant and the ice-water mixture, resulting in high cooling efficiency.

[0049] Specifically, the ice inlet of the cold storage tank 40 is optionally connected to the second ice outlet. The cold storage tank 40 contains an ice-water mixture. The third heat exchanger 33 is installed in the cold storage tank 40 and exchanges heat fully with the ice-water mixture in the cold storage tank 40. After the refrigerant in the third heat exchanger 33 is cooled, it flows to the fourth heat exchanger 34. The fourth heat exchanger 34 and the second fan assembly 32 are opposite each other in the air outlet direction. The second fan assembly 32 is located downstream of the fourth heat exchanger 34. The airflow generated by the second fan assembly 32 is cooled in the area of ​​the fourth heat exchanger 34, and after cooling, cold air is blown out to cool the indoor space.

[0050] It is understandable that after ice is added to the cold storage tank 40, it is to ensure that there is always an ice-water mixture in the cold storage tank 40 and that the temperature of the ice-water mixture is fixed. This can ensure that the temperature of the refrigerant that completes heat exchange in the third heat exchanger 33 is stable, thus ensuring that the outlet air temperature is stable.

[0051] It should be noted that the structure of the cooling unit 30 is not limited to this. In some embodiments, the cooling unit 30 includes a third heat exchanger 33, a fourth heat exchanger 34, and a circulating pump 31. In other embodiments, the cooling unit 30 may include a coolant extractor, a coolant venting unit, and a circulating pump 31. The coolant extractor is connected to the cold storage tank 40, and the coolant venting unit is directly opposite the second fan assembly 32. The coolant extractor, coolant venting unit, and circulating pump 31 are connected in sequence. This eliminates the need for a refrigerant and the need to form a closed refrigerant circulation loop through the third heat exchanger 33, the fourth heat exchanger 34, and the circulating pump 31, which can reduce costs. In the cooling cycle involving water, the cooling temperature is around 0°C and can remain stable, which can also reduce temperature fluctuations and achieve the same technical effect. Further details are omitted here.

[0052] Understandably, in some embodiments, the cold storage tank 40 and the second ice outlet are positioned directly opposite each other in the height direction, with the top of the cold storage tank 40 open, allowing the ice blocks discharged from the second ice outlet to fall directly into the cold storage tank 40 under gravity. In other embodiments, an ice guiding channel is provided between the second ice outlet and the cold storage tank 40. The ice guiding channel can guide the ice blocks discharged from the second ice outlet into the cold storage tank 40 and prevent the ice blocks from splashing water in the cold storage tank 40 during the guiding process, thereby improving the user experience, preventing splashed water from damaging surrounding electrical components, and improving the operational stability of the cold storage air conditioner 100.

[0053] In some embodiments, a drain pump is provided on the cold storage tank 40 for draining water.

[0054] In other words, during the process of adding ice to the cold storage tank 40, the water level in the cold storage tank 40 will gradually increase. In order to prevent the water in the cold storage tank 40 from overflowing, a drainage pump can be set up to control the water in the cold storage tank 40 to a safe water level below the water level line, so as to prevent the water in the cold storage tank 40 from overflowing.

[0055] In addition, in embodiments where a water tank is provided inside the cold storage air conditioner 100 and the water tank contains water, a drain pump can be connected to the water tank to discharge water from the cold storage tank 40 to the water tank, realizing dynamic water circulation, avoiding frequent water replenishment operations, and improving ease of use; the drain pump can also be directly connected to the ice maker 15 to introduce water into the ice maker 15 for easy use in the next ice making. In embodiments where the cold storage air conditioner 100 is connected to the household water supply, the drain pump can be connected to the ice maker 15 to pour water into the ice maker 15. The water discharged by the drain pump into the ice maker 15 is at a lower temperature, which can reduce the initial temperature of the water inside the ice maker 15 during ice making, thereby achieving faster ice making and improving ice making efficiency.

[0056] Furthermore, a water level sensor is installed inside the cold storage tank 40 to detect the water level inside the cold storage tank 40, and to start the drainage pump when the water level inside the cold storage tank 40 reaches the water level threshold.

[0057] In other words, a water level limit can be set for the cold storage tank 40. The maximum height of the liquid level in the cold storage tank 40 is H1, and the corresponding water level limit can be 0.67H1-0.8H1. In this way, on the one hand, water in the cold storage tank 40 can be drained in time to avoid the water level from becoming too high, thereby improving operational stability and preventing water overflow; on the other hand, the water level limit height can be more reasonable, ensuring that the ice blocks floating on the liquid surface in the cold storage tank 40 do not exceed the height of the side plate of the cold storage tank 40 before the cold storage tank 40 is about to reach the water level limit.

[0058] In some embodiments, the cold storage air conditioner 100 further includes a housing, and the cold storage unit 10, the ice storage tank 20, and the cold release unit 30 are all disposed inside the housing.

[0059] Specifically, the outer casing can be constructed as a hollow cylinder, prism, etc., and the inner part of the outer casing defines the installation space. The cold storage unit 10, ice storage tank 20, cold storage tank 40 and cold release unit 30 are all set in the installation space, so that the structure of the cold storage air conditioner 100 is more compact and the arrangement in the indoor space is simpler and more convenient. The bottom of the casing can be equipped with casters to facilitate the movement of the cold storage air conditioner 100 indoors and improve the convenience of use.

[0060] Understandably, the outer casing has a heat dissipation vent and an air outlet. The heat dissipation vent is located downstream of the cold storage unit 10, and the air outlet is located downstream of the cold release unit 30, with the heat dissipation vent and the air outlet being spaced apart.

[0061] In other words, the heat dissipation vents and air outlets on the outer casing are spaced apart. The heat dissipation vents are located downstream of the first fan assembly 12 and the second heat exchanger 14, while the air outlets are located downstream of the second fan assembly 32 and the fourth heat exchanger 34. The air outlets are used to discharge cold air to adjust the indoor space temperature, while the heat dissipation vents are used to dissipate heat from the second heat exchanger 14. This prevents the refrigerant temperature flowing in the refrigeration circuit defined by the first heat exchanger 13, the second heat exchanger 14, and the compressor 11 from becoming too high, thereby improving the working stability and safety of the cold storage air conditioner 100.

[0062] The following is for reference. Figures 1-4 The present invention describes a control method, a control device 200, a cold storage air conditioner 100, and a computer-readable storage medium according to embodiments of the present invention.

[0063] As described above, the cold storage air conditioner 100 of this application embodiment includes: a cold storage unit 10, an ice storage tank 20, a cold storage tank 40, and a cold release unit 30. The cold storage unit 10 is used for making ice. The cold storage unit 10 is connected to the ice storage tank 20 to store ice for domestic use. The cold storage unit 10 is connected to the cold storage tank 40 to store ice for cold release. The cold release unit 30 is connected to the cold storage tank 40 to perform refrigeration.

[0064] It should be noted that ice for domestic use refers to ice blocks stored in ice storage tank 20, while ice for cooling refers to ice blocks stored in cold storage tank 40.

[0065] like Figure 4 As shown, the control method of the cold storage air conditioner 100 according to an embodiment of this application includes:

[0066] Obtain the first ice volume m1 of the ice storage tank 20 and the second ice volume m2 of the cold storage tank 40;

[0067] The working level of the cold storage unit 10 in the cold storage mode is determined based on the first ice volume m1 and the second ice volume m2, and ice is made according to the target ice-making speed va and ice-making time t0 under the working level.

[0068] It is understood that the cold storage air conditioner 100 of this application supplies ice for daily use based on the ice in the ice storage tank 20, and supplies the cooling unit 30 with the ice in the cold storage tank 40. The cold storage air conditioner 100 is used for cooling when it is in the cold storage mode. Therefore, the initial working level of the cold storage unit 10 in the cold storage mode is affected by the second ice amount m2 in the cold storage tank 40 and the first ice amount m1 in the ice storage tank 20.

[0069] This application first obtains the first ice quantity m1 in the ice storage tank 20 and the second ice quantity m2 in the cold storage tank 40, and determines the working position that the cold storage unit 10 should be in at this time based on the first ice quantity m1 and the second ice quantity m2, and makes ice according to the target ice-making speed va and ice-making time t0 under the working position.

[0070] It should be noted that the cold storage mode refers to the mode in which the cold storage unit 10 of the cold storage air conditioner 100 performs ice-making operations to replenish the ice in the ice storage tank 20 and / or the cold storage tank 40. The target ice-making speed va is different under different working levels, and the corresponding speed at which ice is replenished into the cold storage tank 40 and the ice storage tank 20 is different. However, the overall control is based on the first ice quantity m1 and the second ice quantity m2, which can meet the dynamic balance between ice production and ice consumption and maintain the stability of cooling output. Furthermore, ice is made according to the target ice-making speed va within the ice-making time t0. The length of the ice-making time t0 is more reasonable and can improve the stability of ice supply.

[0071] According to the control method of the cold storage air conditioner 100 in the embodiments of this application, the cold storage unit 10 can be controlled to make ice at an appropriate working level according to the amount of ice in the ice storage tank 20 and the cold storage tank 40, so as to avoid the phenomenon of ice breakage in the cold storage tank 40 and / or the ice storage tank 20, ensure that the amount of ice in the cold storage tank 40 can achieve continuous and stable cooling, and that the ice in the ice storage tank 20 can meet the needs of daily life and improve the user experience.

[0072] like Figure 4 As shown, according to some embodiments of this application, determining the operating level of the cold storage unit 10 based on the first ice quantity m1 and the second ice quantity m2, and performing ice making according to the operating level includes:

[0073] Based on the first ice quantity m1, determine the first ice-making speed v1 of the corresponding ice storage tank 20, and based on the second ice quantity m2, determine the second ice-making speed v2 of the corresponding cold storage tank 40.

[0074] The target ice-making speed va is determined based on the first ice-making speed v1 and the second ice-making speed v2 at the working setting.

[0075] Specifically, the cold storage tank 40 is generally enclosed, and a first ice quantity m1 (i.e., the ice storage capacity of the cold storage tank 40) can be detected by an internal sensor. The ice storage tank 20 is semi-open, facilitating the removal and placement of ice blocks, and a second ice quantity m2 (i.e., the ice storage capacity of the ice storage tank 20) ​​can also be detected by an internal sensor. A first ice-making speed v1 is determined based on the first ice quantity m1, and a second ice-making speed v2 is determined based on the second ice quantity m2. This can be achieved by dividing the first ice quantity m1 into several increments, with each increment corresponding to a first ice-making speed v1. A larger increment indicates a larger ice quantity in the ice storage tank 20, and a corresponding... The lower the initial ice-making speed v1, the higher the initial ice-making speed v1. Similarly, the second ice quantity m2 can be divided into multiple increments, with each increment corresponding to a second ice-making speed v2. A larger increment indicates a larger amount of ice in the cold storage tank 40, and the corresponding second ice-making speed v2 is lower. By dynamically adjusting the target ice-making speed va based on the first ice quantity m1 and the second ice quantity m2, the target ice-making speed va can be made more reasonable, ensuring a stable supply of ice in the ice storage tank 20 and the cold storage tank 40, preventing ice shortages in the ice storage tank 20 and the cold storage tank 40, and improving the user experience.

[0076] It is understandable that the target ice-making speed va corresponds to the working level. The target ice-making speed va is different under different working levels. The target ice-making speed va under each working level can be within a range or a fixed value.

[0077] Of course, the determination of the target ice-making speed va in this application is not limited to this. In some other embodiments, it is only necessary to obtain whether there are ice blocks in the cold storage tank 40 and the ice storage tank 20 or whether a certain threshold has been reached. When there are ice blocks in both or a certain threshold has been reached, ice is made according to ice-making speed one. When there are no ice blocks in either, ice is made according to ice-making speed two. When there is ice in the ice storage tank 20 but no ice in the cold storage tank 40, ice is made according to ice-making speed three. When there is no ice in the ice storage tank 20 but ice in the cold storage tank 40, ice is made according to ice-making speed four. Ice-making speed one, ice-making speed two, ice-making speed three and ice-making speed four are different, and the corresponding ice-making time t0 is the same or different, which can also ensure that ice breakage occurs in the cold storage tank 40 or the ice storage tank 20.

[0078] According to some embodiments of this application, the target ice-making speed va under the working position is determined based on the first ice-making speed v1 and the second ice-making speed v2 as follows: va = v1 + v2.

[0079] Specifically, in some embodiments, the first heat exchanger 13 may include a first sub-heat exchanger and a second sub-heat exchanger connected in parallel. The ice box 15 includes a first ice grid and a second ice grid. The first sub-heat exchanger is disposed in the first ice grid and is used to make ice and discharge it to the ice storage tank 20. The second sub-heat exchanger is disposed in the second ice grid and is used to make ice and discharge it to the cold storage tank 40. In this embodiment, the refrigerant flow rate of the first sub-heat exchanger can be controlled based on the first ice-making speed v1, and the refrigerant flow rate of the second sub-heat exchanger can be controlled based on the second ice-making speed v2 to make the target ice-making speed va meet the requirements.

[0080] In some other embodiments, the first heat exchanger 13 may include a first sub-heat exchanger and a second sub-heat exchanger connected in series. The ice grid includes a first ice grid and a second ice grid. The first sub-heat exchanger is disposed in the first ice grid and is used to make ice and discharge it to the ice storage tank 20. The second sub-heat exchanger is disposed in the second ice grid and is used to make ice and discharge it to the cold storage tank 40. At this time, the target ice-making speed va is the sum of the first ice-making speed v1 and the second ice-making speed v2.

[0081] Of course, the ice box 15 can also be constructed as a single piece, and the first heat exchanger 13 is directly installed inside the ice box 15. The ice produced by the first heat exchanger 13 is discharged partly to the cold storage tank 40 and partly to the ice storage tank 20. In this embodiment, the target ice making speed va is also the sum of the first ice making speed v1 and the second ice making speed v2.

[0082] In summary, by controlling the first ice-making speed v1 and the second ice-making speed v2 to achieve control of the target specified speed va, the control of the target ice-making speed va is more reasonable. It can simultaneously achieve control of the ice quantity of the ice storage tank 20 and the cold storage tank 40, thereby improving control accuracy and control stability.

[0083] In some embodiments, the control method further includes:

[0084] Obtain the operating time t1 of the cold storage air conditioner 100 in cooling mode;

[0085] Ice making is performed at the working speed for the available working time t1.

[0086] Each operating setting has an initial target ice-making speed va and an initial ice-making duration t0. The working duration t1 of the cold storage air conditioner 100 is different in different cooling modes. That is, the duration for which the current first ice amount m1 in the cold storage tank 40 can maintain the cooling mode is different. If ice is made according to the initial ice-making duration t0 and the target ice-making speed va, and the current working duration t1 < t0, it may cause ice breakage in the cold storage tank 40. If the current working duration t1 > t0, there will be excessive ice-making capacity, which will increase the energy consumption of the cold storage air conditioner 100.

[0087] Based on this, in cooling mode, the working time t1 of the cold storage air conditioner 100 in cooling mode is obtained in real time, and ice is made according to the working level within the working time t1 to avoid ice-making process or ice interruption.

[0088] See Figure 4 Ice making at the working speed during the working duration t1 includes:

[0089] Record the amount of ice used for each cooling cycle, n1, and the amount of ice used for domestic purposes, n2, as well as the corresponding time information;

[0090] Determine the ice consumption rate v3 for cooling and the ice consumption rate v4 for domestic use;

[0091] The target ice-making speed va is corrected based on the ice consumption rate v3, the ice consumption rate for domestic use v4, and the working time t1.

[0092] Based on the corrected target ice-making speed, ice making is completed at the corresponding target speed within the working time t1.

[0093] It should be noted that the time information refers to the amount of ice used for a certain cooling cycle and the corresponding time information in the cooling mode. For example: at 9:00, the first cooling cycle uses ice with an amount of x; at 10:00, the second cooling cycle uses ice with an amount of y. The cooling ice consumption rate v3 can be determined based on the amount of ice used n1 for each cooling cycle and the corresponding time information. Similarly: at 9:00, the first household ice consumption cycle uses ice with an amount of z; at 10:00, the second household ice consumption cycle uses ice with an amount of i. The casing can determine the household ice consumption rate v4 based on the amount of household ice used n2 for each household cycle and the corresponding time information.

[0094] Furthermore, after determining the cooling ice consumption rate v3 and the domestic ice consumption rate v4, the operating time of the ice in the cold storage tank 40 can be determined based on the cooling ice consumption rate v3 and the second ice quantity m2, and the operating time of the ice in the ice storage tank 20 can be determined based on the domestic ice consumption rate v4 and the first ice quantity m1.

[0095] It should be noted that the working time t1 obtained above can be either the working time of the ice in the cold storage tank 40 or the working time of the ice in the ice storage tank 20. Specifically, the working time of the ice in the cold storage tank 40 can be compared with the working time of the ice in the ice storage tank 20. The shorter of the two working times can be taken as the working time t1.

[0096] Furthermore, the target ice-making rate va is corrected based on the refrigeration ice consumption rate v3, the domestic ice consumption rate v4, and the working time t1, including:

[0097] The first ice-making speed v1 is corrected based on the cooling ice consumption rate v3 and the working time t1, and the second ice-making speed v2 is corrected based on the domestic ice consumption rate v4 and the working time t1.

[0098] The corrected target ice-making speed va is obtained based on the corrected first ice-making speed v1 and the corrected second ice-making speed v2.

[0099] In other words, after determining the working time t1, the first ice-making speed v1 is corrected based on the cooling ice consumption rate v3 and the working time t1, and the second ice-making speed v2 is corrected based on the domestic ice consumption rate v4 and the working time t1, so that the ice-making efficiency under the first ice-making speed v1 is dynamically matched with the cooling ice consumption rate, and the ice-making efficiency under the second ice-making speed v2 is dynamically matched with the domestic ice consumption rate.

[0100] This means that the target ice-making speed va and ice-making time can be dynamically adjusted based on the ice storage status of ice storage tank 20, ice storage status of cold storage tank 40, ice utilization efficiency of cold storage tank 40, ice utilization efficiency of ice storage tank 20, ice-making efficiency of cold storage tank 40, and ice-making efficiency of ice storage tank 20. This satisfies both cold storage and ice utilization needs, avoids ice shortage in ice storage tank 20 or cold storage tank 40, and makes the cooling power of cold storage air conditioner 100 more reasonable during operation, avoiding excessive cooling capacity and increased energy consumption of cold storage air conditioner 100.

[0101] In summary, according to the control method of the cold storage air conditioner 100 in the embodiment of this application, firstly, based on the ice storage situation in the ice storage tank 20 and the cold storage tank 40, ice is made with an initial target ice making speed va and ice making time t0. At this time, the ice making efficiency and ice making time t0 can meet the expected cold release ice consumption and domestic ice consumption needs in the initial state.

[0102] Furthermore, based on the recorded ice consumption cycle for domestic use (i.e., the amount of ice used each time n2 and the time information) and the ice release cycle for cooling (i.e., the amount of ice released each time n1 and the time information), the actual ice release rate v3 and the ice consumption rate for domestic use can be determined, and the actual working time t1 of the ice blocks in the ice storage tank 20 and the cold storage tank 40 can be determined. Then, based on the ice release rate v3 and the ice consumption rate for domestic use v4 and the working time t1, the target ice making rate va can be corrected so that the ice making efficiency meets the usage requirements.

[0103] It should be noted that, in order to match the target ice-making speed va with the actual ice consumption speed, when the working time t1 is higher than the ice-making time t0, the target ice-making speed va should be reduced accordingly, so that the ice production of the target ice-making speed va under the working time t1 is consistent with the ice consumption of the actual ice consumption speed under the working time t1. The working time t1 can also be lower than the ice-making time t0, in which case the target ice-making speed va should be increased accordingly, so that the ice production of the target ice-making speed va under the working time t1 is consistent with the ice consumption of the actual ice consumption speed under the working time t1. This achieves dynamic adjustment. When there is a lot of ice in the cold storage tank 40 and the ice storage tank 20, the output power of the cold storage air conditioner 100 is reduced, and when there is little ice, the output power of the cold storage air conditioner 100 is increased.

[0104] It is understood that, according to some embodiments of this application, the target ice-making speed va can be achieved by adjusting the fan speed of the cold storage unit 10 and the frequency of the compressor 11.

[0105] It should be noted that in some embodiments, determining the working level based on the first ice volume m1 and the second ice volume m2 is a dynamic adjustment process. That is, the first ice volume m1 and the second ice volume m2 are the actual ice volume in the ice storage tank 20 and the actual ice volume in the cold storage tank 40, respectively. The working level is determined based on the amount of actual ice volume. For example, if the first ice volume is 5L and the second ice volume is 5L, one working level is used. However, if the first ice volume is 6L and the second ice volume is 4L, another working level is used. The initial working level is determined by the actual ice volume in the cold storage tank 40 and the ice storage tank 20.

[0106] In other embodiments, determining the operating level of the cold storage unit 10 in the cold storage mode based on the first ice quantity m1 and the second ice quantity m2 may include:

[0107] The first ice quantity m1 is greater than or equal to the first preset ice quantity and the second ice quantity m2 is greater than or equal to the second preset ice quantity, which is in the first gear;

[0108] The first ice quantity m1 is greater than or equal to the first preset ice quantity and the second ice quantity m2 is less than the second preset ice quantity, so it is in the second gear.

[0109] The first ice quantity m1 is less than the first preset ice quantity and the second ice quantity m2 is greater than or equal to the second preset ice quantity, so it is in the third gear.

[0110] The first ice quantity m1 is less than the first preset ice quantity and the second ice quantity m2 is less than the second preset ice quantity, which is in the fourth position; wherein, the volume of the cold storage tank 40 is greater than the volume of the ice storage tank 20.

[0111] The first and second preset ice quantities can be pre-calibrated. For example, the first preset ice quantity can be characterized as no ice in the ice storage tank 20, and the second preset ice quantity can be characterized as no ice in the cold storage tank 40; or the first preset ice quantity can be characterized as 5L of ice in the ice storage tank 20, and the second preset ice quantity can be characterized as 5L of ice in the cold storage tank 40, etc. This application does not make specific limitations.

[0112] The following section will specifically explain the selection of the initial working level of this application, using the first preset ice quantity as the representation that there is no ice in the ice storage tank 20 and the second preset ice quantity as the representation that there is no ice in the cold storage tank 40.

[0113] Cold storage tank There are ice cubes No ice There are ice cubes No ice Ice storage tank There are ice cubes There are ice cubes No ice No ice Cooling mode First gear Second gear Third gear Fourth gear

[0114] In this case, the volume of the cold storage tank 40 of the cold storage air conditioner 100 is larger than the volume of the ice storage tank 20. Therefore, the ice-making efficiency of the first setting is less than that of the third setting, less than that of the second setting, and less than that of the fourth setting, in order to meet the usage requirements of the cold storage air conditioner 100.

[0115] It should be noted that the control method of the cold storage air conditioner 100 in this application embodiment can also control the cold storage unit 10 to connect with the ice storage tank 20 and / or the cold storage tank 40 based on the first ice quantity m1 and the second ice quantity m2.

[0116] Specifically, the first ice quantity m1 represents the ice quantity stored in the ice storage tank 20, and the second ice quantity m2 represents the ice quantity stored in the cold storage tank 40. The connection between the cold storage unit 10 and the ice storage tank 20 and / or the cold storage tank 40 based on the first ice quantity m1 and the second ice quantity m2 can be controlled as follows: when the first ice quantity m1 < the first preset ice quantity and the second ice quantity m2 ≥ the second preset ice quantity, the cold storage unit 10 is connected to the ice storage tank 20; when the first ice quantity m1 ≥ the first preset ice quantity and the second ice quantity m2 < the second preset ice quantity, the cold storage unit 10 is connected to the cold storage tank 40; when the first ice quantity m1 < the first preset ice quantity and the second ice quantity m2 < the second preset ice quantity, the cold storage unit 10 is connected to both the ice storage tank 20 and the cold storage tank 40.

[0117] Of course, when the first ice quantity m1 < the first preset ice quantity and the second ice quantity m2 < the second preset ice quantity, the cold storage unit 10 can be connected to both the ice storage tank 20 and the cold storage tank 40 simultaneously. Alternatively, based on user-set priority conditions, ice can be supplied to the cold storage tank 40 when cold is needed first, and ice can be supplied to the ice storage tank 20 when ice is needed for domestic use. Or, the cold storage unit 10 can be controlled to alternately connect to the ice storage tank 20 and the cold storage tank 40. This application does not make any specific limitations.

[0118] Furthermore, the cold storage unit 10 can be divided into zones. When the first ice quantity m1 is less than the first preset ice quantity and the second ice quantity m2 is less than the second preset ice quantity, the cold storage unit 10 can be divided into a first zone and a second zone. The first zone supplies ice to the cold storage tank 40, and the second zone supplies ice to the ice storage tank 20.

[0119] In this way, the control method of this application can ensure that the ice storage tank 20 or cold storage tank 40 of the cold storage air conditioner 100 can obtain ice in a timely manner when the ice quantity is insufficient, so as to improve the cooling effect and the convenience of using ice for daily life.

[0120] like Figure 2 As shown, the control device 200 of the cold storage air conditioner 100 according to an embodiment of this application includes: an acquisition module 210, configured to acquire a first ice quantity m1 of the ice storage tank 20 and a second ice quantity m2 of the cold storage tank 40; and a control module 220, configured to determine the working level of the cold storage unit 10 in the cold storage mode based on the first ice quantity m1 and the second ice quantity m2, and to perform ice making based on the target ice making speed va and ice making time t0 under the working level.

[0121] According to the control device 200 of the cold storage air conditioner 100 in the embodiment of this application, firstly, based on the ice storage conditions in the ice storage tank 20 and the cold storage tank 40, ice is made at an initial target ice-making speed va and ice-making time t0. At this time, the ice-making efficiency and ice-making time t0 can meet the expected cold release ice consumption and domestic ice consumption needs in the initial state.

[0122] Furthermore, based on the recorded ice consumption cycle (i.e., the amount of ice used each time n2 and the time information) and the ice release cycle (i.e., the amount of ice released each time n1 and the time information), the actual ice release rate v3 and the ice consumption rate v4 can be determined, and the actual working time t1 of the ice blocks in the ice storage tank 20 and the cold storage tank 40 can be determined. Then, based on the ice release rate v3 and the ice consumption rate v4, and the working time t1, the first ice-making rate v1 and the second ice-making rate v2 are corrected to obtain the corrected target ice-making rate va, so that the ice-making efficiency meets the usage requirements, can avoid ice breakage during the refrigeration process, and improve the user experience.

[0123] like Figure 3 As shown, the cold storage air conditioner 100 according to an embodiment of this application includes: a processor 110; a memory 120 for storing executable instructions of the processor 110; wherein the processor 110 is configured to perform the control method as described in the above embodiment. The cold storage air conditioner 100 of this application adopts the above control method, and the technical effects it has are the same as those of the above control method, which will not be repeated here.

[0124] According to the embodiments of this application, when the instructions in the storage medium are executed by the processor 110 of the cold storage air conditioner 100, the cold storage air conditioner 100 is able to perform the control method as described in the above embodiments.

[0125] Below, refer to Figure 1 and Figure 4 The control flow of the control method for the cold storage air conditioner 100 of this application is described in detail.

[0126] like Figure 1 As shown, after the cold storage air conditioner 100 is turned on, it enters the cold storage mode. The cold storage unit 10, which consists of the compressor 11, the first heat exchanger 13, the second heat exchanger 14 and the first fan assembly 12, performs initial cold storage. Part of the ice generated is discharged into the cold storage tank 40 and the other part is discharged into the ice storage tank 20.

[0127] like Figure 4 As shown, after the initial ice storage is completed, the system switches to the cooling mode. In the cooling mode, the first ice volume m1 of the ice storage tank 20 and the second ice volume m2 of the cold storage tank 40 are obtained. The initial working position is determined based on the first ice volume m1 and the second ice volume m2. Ice is then made according to the target ice-making speed va and ice-making time t0 corresponding to the initial working position.

[0128] Then, the amount of ice used for each cooling cycle n1, the amount of ice used for each household cycle n2, and the corresponding time information are obtained, and the working duration t1 is obtained. Based on the working duration t1, the amount of ice used for each cooling cycle n1, and the amount of ice used for each household cycle n2, the cooling ice consumption rate v3 and the household ice consumption rate v4 can be obtained.

[0129] Then, based on the ice consumption rate v3 and the ice consumption rate v4, as well as the working time t1, the actual ice consumption is determined. Based on the actual ice consumption and the working time t1, the required ice-making speed to meet the actual ice consumption within the working time t1 can be determined. The target ice-making speed va is then adjusted based on the required ice-making speed to match the actual ice consumption rate within the working time t1. This allows the cold storage air conditioner 100 to make ice at an appropriate working efficiency in cooling mode, avoiding ice breakage and improving the user experience. At the same time, the output power of the cold storage air conditioner 100 can also be made more reasonable, thus improving the energy consumption of the cold storage air conditioner 100.
