Detailed Implementation

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0022] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0023] The defrosting process of an air conditioner is crucial for maintaining its heating efficiency and protecting the equipment.

[0024] Existing air conditioner defrosting methods achieve this by switching cooling modes, which can cause indoor temperature fluctuations during the defrosting process. Furthermore, while anti-sudden cooling defrosting methods can reduce indoor temperature fluctuations during defrosting, in severe weather conditions such as freezing rain, or in situations with significant heat leakage in the room, this method can cause the air conditioner to frequently perform anti-sudden cooling defrosting.

[0025] Whether it's switching cooling modes to defrost or the frequent defrosting issues caused by existing anti-sudden cooling defrosting methods, both will result in slow indoor temperature rise, affecting the user experience.

[0026] To address the problems existing in related technologies, this disclosure provides a defrosting control method. Figure 1 This is a flowchart illustrating a defrosting control method according to an exemplary embodiment, such as... Figure 1 As shown, the method may include at least the following steps: Step S110. Obtain the environmental parameters for air conditioning operation. The environmental parameters reflect the environmental load of the air conditioning.

[0027] Step S120. Determine the target defrosting mode of the air conditioner based on environmental parameters and perform defrosting. The target defrosting mode includes reverse circulation defrosting mode and anti-sudden cooling defrosting mode.

[0028] In the exemplary embodiments of this disclosure, a corresponding target defrosting mode is selected based on environmental parameters reflecting the environmental load. This not only allows for the selection of a reverse-cycle defrosting mode when defrosting requirements are high, improving the reliability of the defrosting effect and making it suitable for application scenarios with severe weather or serious heat leakage, but also allows for the selection of an anti-sudden cooling defrosting mode when indoor comfort requirements are high, reducing the impact of slow heating caused by defrosting, improving the efficiency of indoor heating and the user experience during defrosting.

[0029] The following is a detailed explanation of each step in the defrosting control method.

[0030] In step S110, environmental parameters for air conditioning operation are obtained, which reflect the environmental load of the air conditioning.

[0031] In the exemplary embodiments of this disclosure, the air conditioner may be an inverter air conditioner or other types of air conditioners, and this exemplary embodiment does not impose any special limitations on it.

[0032] When the air conditioner is not connected to the internet, it can obtain corresponding detection data from its various sensors as environmental parameters. Specifically, the air conditioner's sensors include indoor ambient temperature sensors, outdoor ambient temperature sensors, and outdoor duct temperature sensors.

[0033] Among them, the indoor ambient temperature sensor mainly detects the ambient temperature inside the room and controls the start and stop of the air conditioner; the outdoor ambient temperature sensor is installed on the outdoor radiator to detect the outdoor ambient temperature, which helps the air conditioning system adjust its working status according to the external environment; the outdoor pipe temperature sensor can detect the temperature of the outdoor heat exchanger.

[0034] In step S120, the target defrosting mode of the air conditioner is determined according to the environmental parameters and defrosting is performed. The target defrosting mode includes reverse circulation defrosting mode and anti-sudden cooling defrosting mode.

[0035] In the exemplary embodiments of this disclosure, after obtaining the environmental parameters, a corresponding target defrosting mode can be determined for defrosting. The target defrosting mode includes a reverse-cycle defrosting mode and a sudden-cooling-resistant defrosting mode.

[0036] Specifically, the working principle of the reverse cycle defrosting mode is that when the defrosting mode is detected, the four-way valve switches the direction, changing the system flow path from heating to cooling. The high-temperature gas discharged from the compressor enters the outdoor heat exchanger and melts the frost layer by releasing heat. At the same time, the indoor heat exchanger absorbs heat from the indoor environment and discharges it to the outdoor side for defrosting.

[0037] The working principle of the anti-sudden cooling defrosting mode is that when defrosting is detected, the four-way valve does not switch directions, the system flow path maintains the heating flow path, and the high-temperature gas discharged from the compressor enters the indoor heat exchanger and the outdoor heat exchanger in sequence, simultaneously satisfying the indoor heating and outdoor defrosting. During defrosting, it does not absorb heat from the indoor environment, resulting in better comfort.

[0038] In an optional embodiment, the environmental parameters include outdoor ambient temperature and outdoor pipe temperature; Figure 2 A flowchart illustrating a method for determining a target defrosting pattern is shown, such as... Figure 2 As shown, the method may include at least the following steps: in step S210, a first temperature range in which the outdoor ambient temperature is located is determined, and a second temperature range corresponding to the first temperature range is determined.

[0039] Table 1 shows the first temperature range and the corresponding second temperature range:

[0040] Therefore, the range of the currently detected outdoor ambient temperature can be determined as the first temperature range by using the "Outdoor Ambient Temperature" in Table 1, and the second temperature range corresponding to the first temperature range in the "Outdoor Pipe Temperature" column can be found in Table 1.

[0041] Among them, T 外环 It refers to the outdoor ambient temperature, T. 外管 This is the outdoor pipe temperature. (T) 进入化霜温差1 T 进入化霜温差2 ... T 进入化霜温差8 This is the temperature difference between the outdoor heat exchanger and the outdoor environment during heating operation, used to characterize the frosting condition of the outdoor heat exchanger. This parameter gradually decreases as the outdoor environment temperature decreases. For example, a specific value could be T... 进入化霜温差1 T 进入化霜温差2 =8,T 进入化霜温差3 T 进入化霜温差4 =7,T 进入化霜温差5 T 进入化霜温差6 =6,T 进入化霜温差7 T 进入化霜温差8 =5.

[0042] T 结霜较厚条件下化霜进入温度补偿 This is because frosting occurs faster under harsh temperature conditions, and this compensation value is increased to differentiate it from frosting conditions under normal circumstances. For example, T 结霜较厚条件下化霜进入温度补偿 It can take the value 9.

[0043] In step S220, when the outdoor ambient temperature and the outdoor pipe temperature meet the second temperature range and continue for a preset duration, it is determined to defrost according to the reverse cycle defrosting mode.

[0044] When the outdoor ambient temperature and the outdoor pipe temperature meet the requirements of the second temperature range and can be maintained for a preset duration of 3 minutes, it indicates that the temperature conditions for severe frosting are met, and the reverse circulation defrosting mode can be used for defrosting.

[0045] After determining to perform defrosting in the reverse cycle defrosting mode according to step S220, the target defrosting mode can be switched and updated.

[0046] In an optional embodiment, Figure 3 A flowchart illustrating a method for updating a target defrost mode is shown, as follows: Figure 3 As shown, the method may include at least the following steps: In step S310, the first defrosting duration of running the reverse cycle defrosting mode is obtained.

[0047] In step S320, when the first defrosting time meets the first preset condition, it is determined that defrosting is performed in the anti-sudden cooling defrosting mode.

[0048] The first preset condition can be that the first defrosting time is < 3 / 4 × t 化霜最长时间 , the t 化霜最长时间 This is the longest defrosting time in reverse cycle defrosting mode or anti-sudden cooling defrosting mode.

[0049] When the first defrosting time satisfies the condition that the first defrosting time is less than 3 / 4 × t 化霜最长时间 At that time, it is determined that from the start of the next defrost cycle, the reverse cycle defrost mode will be switched to the anti-sudden cooling defrost mode for defrosting.

[0050] In step S330, if the first defrosting time does not meet the first preset condition, it is determined to continue defrosting according to the reverse cycle defrosting mode.

[0051] When the first defrosting time does not meet the requirement of first defrosting time < 3 / 4 × t 化霜最长时间 When the first preset condition is met, it is determined that the reverse cycle defrosting mode will continue to be used for defrosting in the next defrosting cycle.

[0052] In step S230, if the outdoor ambient temperature and the outdoor pipe temperature do not meet the second temperature range, or do not continue for the preset duration, defrosting is determined to be performed in the anti-sudden cooling defrosting mode.

[0053] When the outdoor ambient temperature and outdoor pipe temperature do not meet the requirements of the second temperature range, or when the outdoor ambient temperature and outdoor pipe temperature meet the requirements of the second temperature range but do not last for the preset duration of 3 minutes, it indicates that the temperature is not under severe frost conditions, and the anti-sudden cooling defrosting mode can be used for defrosting.

[0054] After confirming defrosting in the anti-sudden cooling defrosting mode according to step S230, the defrosting mode of the target can be switched and updated.

[0055] In an optional embodiment, Figure 4 A flowchart illustrating another method for updating the target defrost mode is shown, such as... Figure 4 As shown, the method may include at least the following steps: in step S410, obtaining the second defrosting duration of the anti-sudden cooling defrosting mode.

[0056] In step S420, when the second defrosting duration meets the second preset condition to exit the anti-sudden cooling defrosting mode, and the corresponding outdoor pipe temperature meets the third preset condition, it is determined to defrost according to the reverse cycle defrosting mode.

[0057] The second preset condition could be whether the second defrosting time has reached t. 化霜最长时间 , the t 化霜最长时间 This is the longest defrosting time in reverse cycle defrosting mode or anti-sudden cooling defrosting mode.

[0058] When the second defrosting time reaches t 化霜最长时间 The anti-sudden cooling defrosting mode can be exited at any time, and at the moment of exiting the anti-sudden cooling defrosting mode, the outdoor pipe temperature meets T. 外管 < (T) 防骤冷化霜退出温度 +T 防骤冷化霜除霜不净判断温差 When the third preset condition is met, the reverse cycle defrosting mode can be used in the next defrosting cycle.

[0059] Among them, T 防骤冷化霜退出温度 When the outdoor heat exchanger temperature is greater than or equal to this temperature, the anti-sudden cooling defrosting function can be deactivated. Generally, T... 防骤冷化霜退出温度 The value is 14. T 防骤冷化霜除霜不净判断温差 This is the difference between the outdoor heat exchanger tube temperature and the defrost protection exit temperature at the moment the anti-sudden cooling defrost mode exits. If this difference is less than the temperature difference that determines incomplete defrosting, then there is a risk of incomplete defrosting. Generally, T... 防骤冷化霜除霜不净判断温差 The value is 4.

[0060] Furthermore, the reverse-cycle defrosting mode in this situation can be switched and updated.

[0061] In an optional embodiment, Figure 5 A flowchart illustrating the method for further updating the target defrosting mode is shown, such as... Figure 5 As shown, the method may include at least the following steps: in step S510, the number of times the reverse cycle defrosting mode is run continuously is counted, and the third defrosting duration of the reverse cycle defrosting mode is obtained.

[0062] Generally, the second number of runs can be twice, or other values ​​can be set according to the actual situation. This exemplary embodiment does not impose any special limitations on this.

[0063] In step S520, when the second number of runs is greater than or equal to the second preset number of runs, and the third defrosting duration meets the fourth preset condition, it is determined that defrosting will be performed in the anti-sudden cooling defrosting mode.

[0064] When, in two consecutive second runs, the third defrosting time satisfies the condition that the third defrosting time < (3 / 4 × t) 化霜最长时间 When the fourth preset condition is met, the reverse cycle defrosting mode can be switched to the anti-sudden cooling defrosting mode at the beginning of the next defrosting cycle.

[0065] In step S530, when the second number of runs is less than the second preset number of runs, or the third defrosting time does not meet the fourth preset condition, it is determined to continue defrosting according to the reverse cycle defrosting mode.

[0066] If the second run count is not reached twice consecutively, or if the third defrosting time does not meet the requirement of third defrosting time < (3 / 4 × t) after two consecutive second run counts. 化霜最长时间 When the fourth preset condition is met, the reverse cycle defrosting mode is used to continue defrosting in the next defrosting cycle.

[0067] In an optional embodiment, the environmental parameters include indoor ambient temperature; Figure 6 A flowchart illustrating another method for determining the target defrosting pattern is shown, such as... Figure 6 As shown, the method may include at least the following steps: In step S610, after determining that defrosting is performed in the anti-sudden cooling defrosting mode, the first number of consecutive runs of the anti-sudden cooling defrosting mode is counted.

[0068] In addition to determining the target defrosting mode based on the outdoor ambient temperature, the target defrosting mode can also be determined based on the detected indoor ambient temperature.

[0069] Specifically, during heating operation, the number of consecutive defrosting runs performed under the anti-sudden cooling defrosting mode can be counted. This first number of runs can be within the range of t... 频繁化霜判断时间 The t obtained from internal statistics 频繁化霜判断时间 It can be a preset duration such as 2 hours.

[0070] In step S620, when the first number of runs is greater than or equal to the first preset number of runs, and the indoor ambient temperature is less than or equal to the first preset temperature, it is determined that defrosting will be performed in the reverse cycle defrosting mode.

[0071] The first run of the anti-sudden cooling defrost mode ≥N, and T each time the anti-sudden cooling defrost mode is entered. 内环 ≤T 设定 This allows us to determine that the target defrosting mode is the reverse cycle defrosting mode, in order to perform defrosting.

[0072] Among them, T 内环 It refers to the indoor ambient temperature, T. 设定 It is the preset indoor temperature.

[0073] After determining to perform defrosting in the reverse cycle defrosting mode according to step S620, the target defrosting mode can be switched and updated.

[0074] In an optional embodiment, Figure 7 A flowchart illustrating another method for updating the target defrost mode is shown, such as... Figure 7 As shown, the method may include at least the following steps: In step S710, when the indoor ambient temperature is greater than or equal to the second preset temperature, it is determined to defrost according to the anti-sudden cooling defrosting mode.

[0075] The second preset temperature can be determined by the first preset temperature T. 设定 The value obtained by adding 1 can also be set to other temperature values ​​according to actual conditions. This exemplary embodiment does not impose any special limitations on this.

[0076] The indoor ambient temperature meets T 内环 ≥ (T) 设定 When the temperature reaches +1℃, the reverse cycle defrosting mode is switched to the anti-sudden cooling defrosting mode to start the next defrosting cycle.

[0077] In step S720, when the indoor ambient temperature is lower than the second preset temperature, it is determined to continue defrosting according to the reverse cycle defrosting mode.

[0078] Indoor ambient temperature does not meet T 内环 ≥ (T) 设定 When the temperature reaches +1℃, determine that the reverse cycle defrosting mode will continue to be used for the next defrosting cycle.

[0079] In step S630, when the first number of runs is less than the first preset number of runs, or the indoor ambient temperature is greater than the first preset temperature, it is determined to continue defrosting in the anti-sudden cooling defrosting mode.

[0080] When the first run count of the anti-sudden cooling defrost mode is less than N, or the first run count of the anti-sudden cooling defrost mode is less than N. ≥ N, but when entering the anti-sudden cooling defrost mode, T 内环 >T 设定 This allows us to determine the target defrosting mode as the anti-sudden cooling defrosting mode in order to perform defrosting.

[0081] The defrosting control method in this embodiment will be described in detail below with reference to an application scenario.

[0082] Figure 8 A flowchart illustrating the defrosting control method in an application scenario is shown, such as... Figure 8 As shown, in step S810, the compressor restarts after the initial power-on or heating protection shutdown.

[0083] In step S820, the system continuously runs for 10 minutes to detect when defrosting conditions are met.

[0084] In step S830, when the outdoor ambient temperature and the outdoor heat exchanger tube temperature meet the severe frosting conditions, the normal defrosting process begins.

[0085] If the severe frosting temperature conditions shown in Table 1 are met for 3 consecutive minutes, then the normal defrosting will be performed directly in this cycle, that is, the reverse cycle defrosting mode.

[0086] In step S840, the system switches to anti-sudden cooling defrosting.

[0087] If the defrosting time of a subsequent routine defrosting is less than (3 / 4 × t) 化霜最长时间 If so, the next defrosting cycle can switch back to anti-sudden cold defrosting.

[0088] In step S850, normal defrosting is maintained.

[0089] When the defrosting time of normal defrosting does not meet the requirement of defrosting time < (3 / 4 × t) 化霜最长时间 If so, then the next defrosting cycle will continue with the regular defrosting process.

[0090] In step S860, when the outdoor ambient temperature and the outdoor heat exchanger tube temperature meet the conditions for entering the anti-sudden cooling defrost, the anti-sudden cooling defrost is initiated.

[0091] If the severe frosting temperature conditions shown in Table 1 are not met for 3 consecutive minutes, then the anti-sudden cooling defrosting process will begin.

[0092] In step S870, the process switches to regular defrosting.

[0093] When the anti-sudden cooling defrosting meets the condition of the longest defrosting time, and the exit time T 外管 < (T) 防骤冷化霜退出温度 +T 防骤冷化霜除霜不净判断温差 When this happens, the subsequent cycle will switch to regular defrosting.

[0094] In step S880, the defrosting time for two consecutive cycles is... < (3 / 4×t) 化霜最长时间 ), to prevent sudden cooling and defrosting.

[0095] If the defrosting time for two consecutive cycles is less than (3 / 4 × t) 化霜最长时间 If so, the subsequent defrosting cycle can be switched back to anti-sudden cooling defrosting.

[0096] In step S890, anti-sudden cooling defrosting is maintained.

[0097] The defrosting process exits when the anti-sudden cooling defrosting fails to meet the longest defrosting time condition, or when the anti-sudden cooling defrosting fails to meet the longest defrosting time condition but the exit time does not meet T. 外管 < (T) 防骤冷化霜退出温度 +T 防骤冷化霜除霜不净判断温差 If so, the subsequent defrosting cycle will continue to implement anti-sudden cooling defrosting.

[0098] In the exemplary embodiments of this disclosure, a corresponding target defrosting mode is selected based on environmental parameters reflecting the environmental load. This not only allows for the selection of a reverse-cycle defrosting mode when defrosting requirements are high, improving the reliability of the defrosting effect and making it suitable for application scenarios with severe weather or serious heat leakage, but also allows for the selection of an anti-sudden cooling defrosting mode when indoor comfort requirements are high, reducing the impact of slow heating caused by defrosting, improving the efficiency of indoor heating and the user experience during defrosting.

[0099] Furthermore, in an exemplary embodiment of this disclosure, a defrosting control device is also provided. Figure 9 A schematic diagram of the defrosting control device is shown, such as... Figure 9 As shown, the defrosting control device 900 may include: a parameter acquisition module 910 and a mode determination module 920. Wherein: The parameter acquisition module 910 is configured to acquire environmental parameters for the operation of the air conditioner, the environmental parameters reflecting the environmental load of the air conditioner. The mode determination module 920 is configured to determine the target defrosting mode of the air conditioner based on the environmental parameters and perform defrosting.
