Description

Technical Field

[0001] The present disclosure relates to the technical field of air conditioners, and in particular to an air conditioner defrosting control method, device, controller, storage medium and air conditioner. Background Art

[0002] When the air conditioner is in heating mode, it will absorb heat from the outside, which will lower the surface temperature of the air conditioner outdoor unit. When the temperature drops to a certain level, the water in the air will condense into frost. At this time, when the air conditioner continues to heat, the frost will become thicker and thicker. In order to ensure the heating effect, the air conditioner needs to be defrosted.

[0003] In the related art, air conditioner defrosting methods include conventional defrosting and hot gas defrosting. During the conventional defrosting process, the indoor heat exchanger absorbs heat from the room, causing the indoor temperature to drop. During the hot gas defrosting process, although it does not absorb heat from the room, the defrosting heat is less and the defrosting speed is slower, which still causes the indoor temperature to drop for a longer time. Therefore, no matter which air conditioner defrosting method is used, the temperature of the activity area will drop and the user's physical comfort will be poor. Summary of the invention

[0056] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0057] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0058] Before introducing an air conditioner defrosting control method provided by the present disclosure, an air conditioner provided by the present disclosure is first introduced. Figure 1 is a schematic block diagram of an air conditioner according to an exemplary embodiment. Figure 1 As shown, the air conditioner includes an air conditioner controller, an air conditioner body, an indoor heat exchanger and an air guide plate, wherein the air conditioner controller and the indoor heat exchanger can be arranged inside the air conditioner body, and the air conditioner controller is respectively connected to the air conditioner body, the indoor heat exchanger and the air guide plate by signals, so that the operation of the air conditioner body, the indoor heat exchanger and the air guide plate can be controlled by the air conditioner controller.

[0059] The air conditioner body includes an outer body and an inner body, which are used to realize the heat exchange function of the air conditioner, that is, the cooling and heating functions of the air conditioner, and can obtain user instructions, etc. The inner heat exchanger is arranged inside the inner body of the air conditioner to realize the mutual flow of air in the inner body of the air conditioner and indoor air. The air guide plate is arranged at the air outlet of the inner body of the air conditioner. By adjusting the angle of the air guide plate, the air can be blown from the top or bottom to the inside of the room to realize the change of the air flow direction of the air conditioner. Optionally, in order to improve the air flow effect, the size of the air guide plate is not limited in this disclosure, and can be as large as possible, or can be other specifications.

[0060] Figure 2 is a flow chart of an air conditioner defrosting control method according to an exemplary embodiment. Figure 2 As shown, the air conditioner defrost control method includes the following steps.

[0061] In step S11 , when the air conditioner is running in a heating mode and the defrosting condition is met, the outdoor ambient temperature is obtained.

[0062] For example, in cold weather, the air conditioner usually operates in heating mode, and frost may accumulate on the surface of the air conditioner's outdoor heat exchanger. Defrosting can remove the frost on the surface of the outdoor heat exchanger and restore the normal operation of the equipment. The defrosting condition may include: the cumulative running time of the compressor is greater than the first time threshold, the temperature of the indoor heat exchanger tube, the cumulative time when the indoor heat exchanger tube temperature is less than the indoor temperature is greater than the second time threshold, the difference between the indoor heat exchanger tube temperature and the indoor temperature is greater than the temperature threshold, and the outdoor fan stop time is greater than the third time threshold, etc., wherein the first time threshold, the second time threshold, the temperature threshold and the third time threshold may be the same or different; any of the above conditions may be used as a defrosting condition, and multiple conditions may be combined as a defrosting condition.

[0063] In one implementation, the defrosting condition may be any of the following:

[0064] 1. About 5 minutes after entering the heating mode, the difference between the indoor heat exchanger tube temperature and the indoor temperature decreases by more than 5 degrees and lasts for more than 3 minutes, the cumulative working time of the compressor exceeds 45 minutes, and the indoor heat exchanger tube temperature is less than 48 degrees, which determines that the defrosting conditions are met.

[0065] Or, 2. When the cumulative running time of the compressor exceeds 45 minutes and the continuous running time exceeds 20 minutes, and the temperature of the indoor heat exchanger tube is 16 degrees lower than the indoor temperature, it is determined that the defrosting conditions are met.

[0066] Or, 3. The compressor has been running for more than 3 hours in total and continuously for more than 20 minutes, and the temperature of the indoor heat exchanger tube is 16 degrees lower than the indoor temperature, which is determined to meet the defrosting conditions.

[0067] Or, four, the outdoor fan enters overload protection and stops, the continuous running time of the outdoor fan is greater than 10 minutes when it is started next time, the compressor runs for more than 45 minutes in total or runs continuously for 20 minutes, and the temperature of the indoor heat exchanger tube is less than 48 degrees, which determines that the defrosting conditions are met.

[0068] Or, 5. The external fan stops for two hours to determine that the defrosting conditions are met.

[0069] In step S12, the defrost mode and the operating angle of the air guide plate are determined according to the outdoor ambient temperature.

[0070] For example, defrosting is caused by a low outdoor ambient temperature, and the defrosting mode corresponding to different outdoor ambient temperatures and the operating angle of the air guide plate can be determined according to the outdoor ambient temperature.

[0071] In step S13, heat is stored indoors according to the operating angle of the air guide plate.

[0072] For example, the defrost modes may include conventional defrost and hot gas defrost. Different defrost modes correspond to different operating angles of the air guide plates. The defrost mode is determined by the outdoor ambient temperature, and then the operating angle corresponding to the defrost mode is selected. By adjusting the wind shield to the operating angle corresponding to the defrost mode, the air can be guided to a specific area, thereby promoting heat transfer in the area, improving the uniform distribution and transfer efficiency of heat, and achieving a good indoor heat storage effect.

[0073] In step S14, after the heat storage is completed, the air conditioner is controlled to perform defrosting according to the defrost mode.

[0074] Through the guidance of the air guide plate, after completing the heat storage in a specific area, defrosting in the corresponding defrost mode is performed, so that the air conditioner can also increase the indoor temperature during the defrost period and avoid the cooling problem caused by defrosting.

[0075] In the above technical solution, when the air conditioner is running in heating mode and meets the defrosting conditions, the outdoor ambient temperature is obtained; the defrosting mode and the operating angle of the air guide plate are determined according to the outdoor ambient temperature; the indoor heat is stored according to the operating angle of the air guide plate; after the heat storage is completed, the air conditioner is controlled to defrost according to the defrosting mode. Through the above solution, the indoor heat can be stored through the defrosting mode determined by the outdoor ambient temperature and the operating angle of the air guide plate, so that the air conditioner can also increase the indoor temperature during the defrosting period, thereby improving the user comfort.

[0076] Figure 3 is a flow chart of another air conditioner defrosting control method according to an exemplary embodiment. Figure 3 As shown, the process of determining the defrost mode and the operating angle of the air guide plate according to the outdoor ambient temperature in the above step S12 includes the following steps.

[0077] In step S121 , a defrost mode and a heat storage mode corresponding to the defrost mode are determined according to the outdoor ambient temperature.

[0078] For example, when the outdoor ambient temperature drops to a certain level, the defrost mode will be triggered. The defrost process of the air conditioner is completed by absorbing a certain amount of heat. When the outdoor ambient temperature is different, the degree of frost of the air conditioner may be different. Therefore, the heat required for different defrost modes may be different. Therefore, the defrost mode and the heat storage mode corresponding to the defrost mode can be determined according to the outdoor ambient temperature.

[0079] In step S122, the operating angle of the air guide plate is determined according to the heat storage mode.

[0080] For example, by adjusting the angle of the air guide plate, the direction and speed of air flow can be controlled so that heat is transferred to a designated area, thereby storing the heat required for the corresponding heat storage mode for the designated area.

[0081] In one implementation, the air conditioner can support hot gas defrosting and conventional defrosting, wherein the heat storage mode corresponding to the hot gas defrosting is the first heat storage mode, and the heat storage mode corresponding to the conventional defrosting is the second heat storage mode. Figure 4 is a flow chart of another air conditioner defrosting control method according to an exemplary embodiment. Figure 4 As shown, the step S121 described above of determining the defrost mode according to the outdoor ambient temperature and the heat storage mode corresponding to the defrost mode includes the following steps.

[0082] In step S1211, when the outdoor ambient temperature is greater than the set outdoor ambient temperature, the defrost mode is determined to be hot gas defrost, and the heat storage mode is determined to be the first heat storage mode.

[0083] For example, during hot gas defrosting, defrosting is performed by the heat generated by the indoor heat exchanger. The defrosting heat is relatively small and the defrosting speed is relatively slow. It is suitable for the case where the outdoor temperature is not particularly low. Therefore, when the outdoor ambient temperature is greater than the set outdoor ambient temperature, the defrost mode is determined to be hot gas defrost, and the heat storage mode is determined to be the first heat storage mode.

[0084] In step S1212, when the outdoor ambient temperature is less than or equal to the set outdoor ambient temperature, the defrost mode is determined to be the normal defrost mode and the heat storage mode is determined to be the second heat storage mode.

[0085] For example, during normal defrosting, the indoor heat exchanger absorbs heat from the indoor room for defrosting, which is also called reverse cycle defrosting. The heat for defrosting is relatively sufficient, and rapid defrosting can be achieved. It is suitable for conditions with low outdoor temperatures. Therefore, when the outdoor ambient temperature is less than or equal to the set outdoor ambient temperature, the defrost mode is determined to be normal defrosting, and the heat storage mode is determined to be the second heat storage mode.

[0086] Among them, the first heat storage mode is to store heat for the air below the air conditioner, and the second heat storage mode is to store heat for the air above the air conditioner.

[0087] For example, the first heat storage mode stores heat in the air below the air conditioner, which can increase the heat below the air conditioner; the second heat storage mode stores heat in the air above the air conditioner, which can increase the heat above the air conditioner.

[0088] Figure 5 is a flow chart of another air conditioner defrosting control method according to an exemplary embodiment. Figure 5 As shown, determining the operating angle of the air guide plate according to the heat storage mode described in the above step S122 includes the following steps.

[0089] In step S1221, when the heat storage mode is the first heat storage mode, the operating angle of the air guide plate is the first angle.

[0090] In step S1222, when the heat storage mode is the second heat storage mode, the operating angle of the air guide plate is the second angle.

[0091] Among them, the first angle is the angle towards the bottom of the air conditioner, and the second angle is the angle towards the top of the air conditioner.

[0092] For example, in the first heat storage mode, the air guide plate is directed toward the angle below the air conditioner, and the air outlet of the air conditioner flows toward the angle below the air conditioner, that is, the air can be blown to the lower space of the room. In the second heat storage mode, the air guide plate is directed toward the angle above the air conditioner, and the air outlet of the air conditioner flows toward the angle above the air conditioner, that is, the air can be blown to the upper space of the room.

[0093] Figure 6 is a flow chart of another air conditioner defrosting control method according to an exemplary embodiment. Figure 6 As shown, the heat storage in the room according to the operating angle of the air guide plate described in the above step S13 includes the following steps.

[0094] In step S131, when the defrost mode is hot gas defrost, the air guide plate is operated to a first angle, and the compressor of the air conditioner is controlled to operate in a first heat storage mode according to a first heat storage frequency.

[0095] or,

[0096] In step S132, when the defrost mode is normal defrost, the air guide plate is operated to a second angle, and the compressor of the air conditioner is controlled to operate in a second heat storage mode according to a second heat storage frequency.

[0097] Among them, the first angle is the angle towards the bottom of the air conditioner, the second angle is the angle towards the top of the air conditioner, the first heat storage mode is to store heat for the air below the air conditioner, and the second heat storage mode is to store heat for the air above the air conditioner.

[0098] For example, by moving the air guide plate toward the bottom of the air conditioner, the compressor of the air conditioner can be controlled to store heat in the air below the air conditioner at the first heat storage frequency, thereby increasing the temperature of the personnel activity area and ensuring that the temperature of the activity area will not drop to a particularly low temperature during the hot gas defrosting process, thereby improving user comfort. By moving the air guide plate toward the top of the air conditioner, the compressor of the air conditioner can be controlled to store heat in the air above the air conditioner at the second heat storage frequency, thereby increasing the absorption of heat by the indoor heat exchanger, thereby accelerating defrosting, allowing the air conditioner to quickly resume the indoor heating mode, and improving user comfort. Optionally, the indoor heat can be stored by increasing the operating frequency of the compressor.

[0099] Figure 7 is a flow chart of another air conditioner defrosting control method according to an exemplary embodiment. Figure 7As shown, after completing the heat storage described in the above step S14, controlling the air conditioner to defrost according to the defrost mode includes the following steps.

[0100] In step S141, when the defrost mode is hot gas defrost, the operation time of the heat storage and the indoor temperature are monitored.

[0101] In step S142, when the operation time of heat storage is greater than the set time, or the indoor temperature is greater than the set indoor ambient temperature, it is determined that the heat storage is completed.

[0102] In step S143, the air conditioner is controlled to perform hot gas defrosting.

[0103] For example, in the hot gas defrost mode, the heat storage operation time and the indoor temperature are monitored to determine whether the heat storage is completed; optionally, the heat storage operation time can be set according to the design and performance of the air conditioner, the indoor and outdoor temperature difference and the needs of the user. When the heat storage operation time is monitored to be greater than the set time, it can be determined that the heat storage is completed and the hot gas defrost can be started; or, when the indoor temperature is monitored to be greater than the set indoor temperature, it means that the indoor temperature meets the user's needs, and it can also be determined that the heat storage is completed and the hot gas defrost can be started. Optionally, the indoor temperature can be the most comfortable air-conditioning temperature for the human body, such as about 26°C. The present disclosure does not limit the set time and indoor ambient temperature.

[0104] Figure 8 is a flow chart of another air conditioner defrosting control method according to an exemplary embodiment. Figure 8 As shown, after completing the heat storage described in the above step S14, controlling the air conditioner to defrost according to the defrost mode includes the following steps.

[0105] In step S144, when the defrost mode is normal defrost, the operation time of the heat storage and the temperature of the heat exchanger tube of the indoor unit of the air conditioner are monitored;

[0106] In step S145, when the heat storage operation time is greater than the set time, or the indoor heat exchanger tube temperature is greater than the set indoor heat exchanger tube temperature, the air conditioner is controlled to perform conventional defrosting.

[0107] For example, in the conventional defrost mode, the heat storage operation time and the temperature of the heat exchanger tube of the indoor unit of the air conditioner are monitored to determine whether the heat storage is completed; optionally, in the conventional defrost mode, the heat storage operation time can be set according to the design and performance of the air conditioner, the indoor and outdoor temperature difference and the needs of the user. When the heat storage operation time is monitored to be greater than the set time, it can be determined that the heat storage has been completed and the conventional defrost can be started; or, when the temperature of the heat exchanger tube of the indoor unit is monitored to be greater than the set temperature of the heat exchanger tube of the indoor unit, it can be determined that the heat storage has been completed and the conventional defrost can be started. The temperature of the heat exchanger tube of the indoor unit can be the temperature of the heat exchanger pipe of the indoor unit.
