Detailed implementation manners

[0021] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0022] It should be noted that all actions of obtaining signals, information, or data in the present disclosure are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where it is located and obtaining the authorization given by the owner of the corresponding device.

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

[0024] The existing air conditioner defrosting method is achieved by switching to the cooling mode, which will cause temperature fluctuations in the indoor environment during defrosting. Further, although the anti-freezing and sudden-cooling defrosting method can reduce the temperature fluctuations in the indoor environment during defrosting, in severe weather such as freezing rain, or in the case of serious heat leakage in the room, this method will cause the air conditioner to frequently perform anti-freezing and sudden-cooling defrosting.

[0025] Whether it is the defrosting method of switching to the cooling mode, or the frequent defrosting problem brought by the existing anti-freezing and sudden-cooling defrosting method, both will cause the indoor temperature to rise slowly, affecting the user experience.

[0026] In view of the problems existing in the related art, the present disclosure provides a defrost control method, Figure 1 which is a flowchart of a defrost control method shown according to an exemplary embodiment, as Figure 1 shown, and the method may at least include the following steps: Step S110. Obtain the environmental parameters of the air conditioner operation, and the environmental parameters reflect the environmental load of the air conditioner.

[0027] Step S120. Determine the target defrost mode of the air conditioner for defrosting according to the environmental parameters, and the target defrost mode includes the reverse cycle defrost mode and the anti-freezing and sudden-cooling defrost mode.

[0028] In an exemplary embodiment of the present disclosure, a corresponding target defrosting mode is selected for defrosting based on environmental parameters reflecting the environmental load. It can not only select the reverse cycle defrosting mode when the defrosting requirements are high, improve the reliability of the defrosting effect, and be applicable to application scenarios with bad weather or serious heat leakage, but also select the anti-sudden-cooling defrosting mode when the indoor comfort requirements are high, reduce the impact of slow temperature rise caused by defrosting, and improve the indoor heating efficiency and user experience during defrosting.

[0029] The following will describe each step of the defrosting control method in detail.

[0030] In step S110, environmental parameters during the operation of the air conditioner are obtained, and the environmental parameters reflect the environmental load of the air conditioner.

[0031] In an exemplary embodiment of the present disclosure, the air conditioner can be a variable-frequency air conditioner or other air conditioners, and this exemplary embodiment does not make special limitations on this.

[0032] When the air conditioner is in an unconnected state, corresponding detection data can be obtained from each sensor of the air conditioner as environmental parameters. Specifically, the sensors of the air conditioner include an indoor environmental temperature sensor, an outdoor environmental temperature sensor, an outdoor pipe temperature sensor, etc.

[0033] Among them, the indoor environmental temperature sensor mainly detects the environmental temperature in the room and controls the start and stop of the air conditioner; the outdoor environmental temperature sensor is installed on the outdoor radiator and is used to detect the outdoor environmental temperature, which helps the air conditioner system adjust its working state 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 for defrosting according to the environmental parameters, and the target defrosting mode includes a reverse cycle defrosting mode and an anti-sudden-cooling defrosting mode.

[0035] In an exemplary embodiment of the present disclosure, after obtaining the environmental parameters, the corresponding target defrosting mode can be determined for defrosting. Among them, the target defrosting mode includes a reverse cycle defrosting mode and an anti-sudden-cooling defrosting mode.

[0036] Specifically, the working principle of the reverse cycle defrosting mode is that when it is detected that defrosting is entered, the four-way valve switches directions, so that the system flow path is switched from the heating flow path to the cooling flow path. 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 and discharges it to the outdoor side for defrosting.

[0037] The working principle of the anti-sudden-cooling defrosting mode is that when it is detected that defrosting is about to start, the four-way valve does not change direction, and the system flow path maintains the heating flow path. The high-temperature gas discharged from the compressor enters the indoor heat exchanger and the outdoor heat exchanger in sequence, simultaneously meeting the heating of the indoor environment and defrosting on the outdoor side. During defrosting, heat is not absorbed from the indoor environment, resulting in better comfort.

[0038] In an alternative embodiment, the environmental parameters include the outdoor ambient temperature and the outdoor pipe temperature; Figure 2 A flowchart showing a method for determining a target defrosting mode is presented, as Figure 2 shown. The method may at least include the following steps: In step S210, determine the first temperature range in which the outdoor ambient temperature is located, and determine the corresponding second temperature range.

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

[0040] Therefore, the range in which the currently detected outdoor ambient temperature is located can be determined as the first temperature range through the "outdoor ambient temperature" in Table 1, and the corresponding second temperature range in the "outdoor pipe temperature" column of Table 1 can be queried.

[0041] Where T 外环 is the outdoor ambient temperature, and T 外管 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 is the difference between the outdoor heat exchanger of the air conditioner and the outdoor ambient temperature during the heating operation, which is used to characterize the frosting condition of the outdoor heat exchanger. This parameter gradually decreases as the outdoor ambient temperature decreases. For example, the specific value situation can 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 is because the frosting speed increases under the temperature conditions of severe frosting, and this compensation value is added to distinguish from the frosting conditions in normal environments. For example, T 结霜较厚条件下化霜进入温度补偿 can be taken as 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 last for a preset duration of 3 minutes, it indicates that the temperature conditions for severe frosting are met at this time, and the reverse cycle defrosting mode can be adopted for defrosting.

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

[0046] In an alternative embodiment, Figure 3 a flowchart showing a method for updating the target defrosting mode is shown, as Figure 3 shown, the method may at least include the following steps: In step S310, obtain the first defrosting duration of operating the reverse cycle defrosting mode.

[0047] In step S320, when the first defrosting duration meets the first preset condition, determine to defrost in the anti - sudden - cooling defrosting mode.

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

[0049] When the first defrosting duration meets the condition that the first defrosting duration < 3 / 4×t 化霜最长时间 , determine to switch the reverse cycle defrosting mode to the anti - sudden - cooling defrosting mode for defrosting starting from the next defrosting cycle.

[0050] In step S330, when the first defrosting duration does not meet the first preset condition, determine to continue defrosting in the reverse cycle defrosting mode.

[0051] When the first defrosting duration does not meet the first preset condition that the first defrosting duration < 3 / 4×t 化霜最长时间 , determine to continue using the reverse cycle defrosting mode for defrosting in the next defrosting cycle.

[0052] In step S230, when the outdoor ambient temperature and the outdoor pipe temperature do not meet the second temperature range, or do not last for the preset duration, determine to defrost in the anti - sudden - cooling defrosting mode.

[0053] When the outdoor ambient temperature and the outdoor pipe temperature do not meet the requirements of the second temperature range, or the outdoor ambient temperature and the 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 conditions are not in the temperature conditions for severe frosting, and the anti - sudden - cooling defrosting mode can be adopted for defrosting.

[0054] After determining to defrost in accordance with the anti-sudden-cooling defrost mode in step S230, the target defrost mode can be switched and updated.

[0055] In an alternative embodiment, Figure 4 A schematic flowchart showing another method for updating the target defrost mode is shown, as Figure 4 shown. The method may at least include the following steps: In step S410, obtain a second defrost duration of operating the anti-sudden-cooling defrost mode.

[0056] In step S420, when the second defrost duration meets a second preset condition to exit the anti-sudden-cooling defrost mode and the corresponding outdoor pipe temperature meets a third preset condition, determine to defrost in accordance with the reverse-cycle defrost mode.

[0057] The second preset condition may be whether the second defrost duration reaches t 化霜最长时间 , and this t 化霜最长时间 is the longest defrost duration in the reverse-cycle defrost mode or the anti-sudden-cooling defrost mode.

[0058] When the second defrost duration reaches t 化霜最长时间 , the anti-sudden-cooling defrost mode can be exited. And at the moment of exiting the anti-sudden-cooling defrost mode, when the outdoor pipe temperature meets the third preset condition that 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 ), defrosting can be performed using the reverse-cycle defrost mode in the next defrost cycle.

[0059] Among them, T 防骤冷化霜退出温度 is the temperature at which defrosting can be exited when the outdoor heat exchanger temperature is greater than or equal to this temperature. Generally, T 防骤冷化霜退出温度 takes a value of 14. T 防骤冷化霜除霜不净判断温差 is the difference between the outdoor heat exchanger pipe temperature and the anti-sudden-cooling defrost exit temperature at the moment of exiting the anti-sudden-cooling defrost mode. When this difference is less than the determination temperature difference for incomplete defrosting, it is considered that there is a risk of incomplete defrosting. Generally, T 防骤冷化霜除霜不净判断温差 takes a value of 4.

[0060] Furthermore, the reverse-cycle defrost mode in this case can also be switched and updated.

[0061] In an alternative embodiment, Figure 5 A schematic flowchart showing a further method for updating the target defrost mode is shown, as Figure 5 shown. The method may at least include the following steps: In step S510, count the second number of consecutive operations of the reverse-cycle defrost mode and obtain a third defrost duration of operating the reverse-cycle defrost mode.

[0062] Generally, the second number of runs can be two, or other values can be set according to the actual situation, and this exemplary embodiment does not make special limitations on this.

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

[0064] When, under the second number of runs for two consecutive times, the third defrosting duration meets the fourth preset condition that the third defrosting duration < (3 / 4 × t 化霜最长时间 )), it is possible to convert the reverse-cycle defrosting mode to the anti-sudden-cooling defrosting mode for defrosting 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, or the third defrosting duration does not meet the fourth preset condition, it is determined to continue to perform defrosting according to the reverse-cycle defrosting mode.

[0066] When the second number of runs has not reached two consecutive times, or when, under the second number of runs for two consecutive times, the third defrosting duration does not meet the fourth preset condition that the third defrosting duration < (3 / 4 × t 化霜最长时间 ), it is determined to continue to use the reverse-cycle defrosting mode for defrosting in the next defrosting cycle.

[0067] In an alternative embodiment, the environmental parameter includes the indoor environmental temperature; Figure 6 The flowchart shows another method for determining the target defrosting mode. As Figure 6 shown, the method may at least include the following steps: In step S610, after determining to perform defrosting according to the anti-sudden-cooling defrosting mode, count the first number of runs of continuously operating in the anti-sudden-cooling defrosting mode.

[0068] In addition to determining the target defrosting mode according to the outdoor environmental temperature, it is also possible to determine the target defrosting mode according to the detected indoor environmental temperature.

[0069] Specifically, during the heating operation, the first number of runs of continuously performing defrosting according to the anti-sudden-cooling defrosting mode can be counted. The first number of runs can be counted within t 频繁化霜判断时间 , and the t 频繁化霜判断时间 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, and the indoor environmental temperature is less than or equal to the first preset temperature, it is determined to perform defrosting according to the reverse-cycle defrosting mode.

[0071] When the first number of runs of the anti-sudden-cooling defrosting mode ≥N, and each time when entering the anti-freezing defrosting mode, T 内环 ≤T 设定 , it can be determined that the target defrosting mode is the reverse cycle defrosting mode to perform defrosting.

[0072] Wherein, T 内环 is the indoor ambient temperature, and T 设定 is the first preset temperature of the indoor that is preset in advance.

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

[0074] In an alternative embodiment, Figure 7 a flowchart showing yet another method for updating the target defrosting mode is shown. As Figure 7 shown, the method may at least include 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 perform defrosting according to the anti-freezing defrosting mode.

[0075] Wherein, the second preset temperature may be obtained by adding 1 to the first preset temperature T 设定 , or other temperature values may be set according to the actual situation, and this exemplary embodiment does not make special limitations on this.

[0076] When the indoor ambient temperature satisfies T 内环 ≥ (T 设定 +1°C), it is determined that the reverse cycle defrosting mode will be converted to the anti-freezing defrosting mode at the start of the next defrosting cycle to perform defrosting.

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

[0078] When the indoor ambient temperature does not satisfy T 内环 ≥ (T 设定 +1°C), it is determined that the reverse cycle defrosting mode will continue to be used for defrosting in the next defrosting cycle.

[0079] In step S630, when the first number of operations is less than the first preset number, or the indoor ambient temperature is greater than the first preset temperature, it is determined to continue to perform defrosting according to the anti-freezing defrosting mode.

[0080] When the first number of operations of the anti-freezing defrosting mode < N, or the first number of operations of the anti-freezing defrosting mode ≥ N, but when entering the anti-freezing defrosting mode, T 内环 > T 设定 , it can be determined that the target defrosting mode is the anti-freezing defrosting mode to perform defrosting.

[0081] The defrost control method in the embodiments of the present disclosure will be described in detail below in combination with an application scenario.

[0082] Figure 8 The flowchart of the defrost control method in the application scenario is shown. As Figure 8 shown, in step S810, the compressor restarts after the first power-on or after the heating protection stops and then restarts.

[0083] In step S820, it continuously runs for 10 minutes to detect the conditions for entering defrost.

[0084] In step S830, when the outdoor ambient temperature and the temperature of the outdoor heat exchanger tubes meet the severe frosting entry conditions, it enters the conventional defrost.

[0085] If it continuously detects that the severe frosting temperature conditions shown in Table 1 are met for 3 minutes, then this cycle directly performs the conventional defrost, that is, the reverse cycle defrost mode.

[0086] In step S840, it switches to the anti-sudden-cooling defrost.

[0087] If the defrost time of a subsequent conventional defrost < (3 / 4 × t 化霜最长时间 ), then the next defrost cycle can switch back to the anti-sudden-cooling defrost.

[0088] In step S850, it maintains the conventional defrost.

[0089] When the defrost time of the conventional defrost does not satisfy the defrost time < (3 / 4 × t 化霜最长时间 ), then the next defrost cycle continues to perform the conventional defrost.

[0090] In step S860, when the outdoor ambient temperature and the temperature of the outdoor heat exchanger tubes meet the anti-sudden-cooling defrost entry conditions, it enters the anti-sudden-cooling defrost.

[0091] If it continuously detects that the severe frosting temperature conditions shown in Table 1 are not met for 3 minutes, then it enters the anti-sudden-cooling defrost.

[0092] In step S870, it switches to the conventional defrost.

[0093] When the anti-sudden-cooling defrost exits when meeting the longest defrost time condition, 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 ), then the subsequent cycle switches to the conventional defrost.

[0094] In step S880, when the defrost time of the conventional defrost in two consecutive cycles ＜ < (3 / 4 × t 化霜最长时间 ), it switches to the anti-sudden-cooling defrost.

[0095] If the defrosting time in two consecutive cycles is < (3 / 4 × t 化霜最长时间 ), the subsequent defrosting cycle can return to anti - sudden - cooling defrosting.

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

[0097] When anti - sudden - cooling defrosting exits because it does not meet the longest defrosting time condition, or when anti - sudden - cooling defrosting exits because it meets the longest defrosting time condition, but the exit moment 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 ), then the subsequent defrosting cycle continues to perform anti - sudden - cooling defrosting.

[0098] In the exemplary embodiment of the present disclosure, the corresponding target defrosting mode is selected based on the environmental parameters reflecting the environmental load for defrosting. It can not only select the reverse - cycle defrosting mode when the defrosting requirements are high, improve the reliability of the defrosting effect, and be applicable to application scenarios with bad weather or serious heat leakage, but also select the anti - sudden - cooling defrosting mode when the indoor comfort requirements are high, reduce the impact of slow temperature rise caused by defrosting, and improve the efficiency of indoor temperature rise and the user experience during defrosting.
