[0002] A split air conditioner generally consists of two parts, an indoor unit and an outdoor unit. The air inlet of the indoor unit is usually provided with a filter to filter the air entering the indoor unit for heat exchange.

[0044] like Figure 1-Figure 5 As shown, the present invention provides a method for monitoring filter clogging, the filter clogging monitoring method comprising:

[0045] S100, after the air conditioner is started, determining the actual temperature reaching time for the air conditioner to adjust the first indoor temperature to the first set temperature.

[0046] Among them, the first indoor temperature is the actual temperature of the current indoor environment, the first set temperature is the indoor target temperature that the user wants to adjust, and the actual temperature reaching time is the actual time for the first indoor temperature to rise to / drop to the first set temperature.

[0047] S200, determining a theoretical temperature reaching time required for the air conditioner to adjust the first indoor temperature to a first set temperature.

[0048] The theoretical temperature-reaching time is the theoretical time for raising the first indoor temperature to / lowering the first set temperature, calculated based on the operating parameters of the air conditioner, etc., when the filter is not dirty or clogged.

[0049] S300, after determining that the actual temperature-reaching time is greater than the theoretical temperature-reaching time, determining that the filter is clogged.

[0050] Among them, since the theoretical heating time is the standard time for the air conditioner to raise the actual indoor temperature to the target temperature when the filter is not dirty or clogged, when the actual heating time is greater than the theoretical heating time, it can be determined that the filter is dirty or clogged at this time.

[0051] It can be understood that the above-mentioned filter clogged monitoring method determines the actual time it takes for the air conditioner to adjust the first indoor temperature to the first set temperature after the air conditioner is started, and determines the theoretical time it takes for the air conditioner to adjust the first indoor temperature to the first set temperature. Based on the actual time and the theoretical time, it is determined whether the filter is clogged. After the actual time is greater than the theoretical time, it is determined that the filter is clogged. Then, the filter clogged time can be accurately determined according to different usage environments.

[0052] In some embodiments, before determining that the actual temperature-reaching time is greater than the theoretical temperature-reaching time, the filter blockage monitoring method further includes:

[0053] A first difference between the actual temperature-reaching time and the theoretical temperature-reaching time is determined.

[0054] The actual temperature reaching time is t 实际 , the theoretical temperature reaching time is t 理论 , the first difference is Δt1, where Δt1=t 实际 -t 理论 .

[0055] It is determined whether the first difference is greater than a first preset value.

[0056] The first preset value is data pre-stored in the controller of the air conditioner. The first preset value is generally a positive number so that there is a certain allowable error in the judgment of the actual temperature-reaching time and the theoretical temperature-reaching time. That is, under normal circumstances, even if the filter is not dirty or blocked, the actual temperature-reaching time may be greater than the theoretical temperature-reaching time and will not be completely equal to the theoretical temperature-reaching time. Therefore, the first preset value is set to a positive number to allow a certain allowable error between the actual temperature-reaching time and the theoretical temperature-reaching time.

[0057] When it is determined that the first difference is greater than the first preset value, it is determined that the actual temperature-reaching time is greater than the theoretical temperature-reaching time.

[0058] Among them, when the first difference is greater than the first preset value, it means that the actual temperature-reaching time is greater than the theoretical temperature-reaching time and far exceeds the allowable deviation time. Then it can be determined that the actual temperature-reaching time is greater than the theoretical temperature-reaching time, that is, the filter is dirty and clogged.

[0059] In some embodiments, the filter blockage monitoring method further includes:

[0060] S400, determining a first temperature reaching time for the air conditioner to adjust the first indoor temperature to the first set temperature when the filter of the air conditioner reaches a set dirty and blocked threshold.

[0061] The size of the dirty blockage threshold represents the degree of dirtiness of the filter. The dirty blockage threshold is set so that when the degree of dirtiness of the filter reaches a certain level, the air conditioner needs to remind and issue a dirty blockage alarm.

[0062] Among them, the first temperature-reaching time is the temperature adjustment time for the air conditioner to adjust the indoor temperature from the first indoor temperature to the first set temperature when the filter is at a set threshold level of dirt and blockage. Since the filter is dirty and blocked to a certain extent, the cooling capacity / heating capacity of the air conditioner will be affected, thereby affecting the temperature adjustment time.

[0063] Among them, different dirtiness and clogging thresholds correspond to the degree of dirtiness and clogging of the filter, and further correspond to different first temperature-reaching times.

[0064] S500: After determining that the actual temperature-reaching time is greater than or equal to the first temperature-reaching time, it is determined that the degree of dirtiness and blockage of the filter reaches a set dirtiness and blockage threshold, and a dirtiness and blockage alarm is issued.

[0065] Among them, when the actual temperature reached is greater than or equal to the first temperature reaching time, it is determined that the degree of dirtiness and blockage of the filter has reached the condition requiring an alarm reminder, and then the air conditioner is controlled to issue a dirtiness and blockage alarm.

[0066] In some embodiments, before determining that the actual temperature reaching time is greater than or equal to the first temperature reaching time, the filter screen dirty blockage monitoring method further includes:

[0067] A second difference between the actual temperature-reaching time and the first temperature-reaching time is determined.

[0068] The actual temperature reaching time is t 实际 , the first temperature reaching time is t 脏堵 , the second difference is Δt2, where Δt2 = t 实际 -t 脏堵 .

[0069] It is determined whether the second difference is greater than a second preset value.

[0070] The second preset value is data pre-stored in the controller of the air conditioner, and the second preset value is generally a positive number, so that there is a certain allowable error in the judgment of the actual temperature-reaching time and the first temperature-reaching time. That is, in some cases, due to other factors, the actual temperature-reaching time is greater than the first temperature-reaching time, but the actual degree of clogging of the filter has not reached the degree of clogging corresponding to the set clogging threshold, so the second preset value is set to a positive number, allowing a certain allowable error between the actual temperature-reaching time and the first temperature-reaching time.

[0071] When it is determined that the second difference is greater than or equal to the second preset value, it is determined that the actual temperature-reaching time is greater than or equal to the first temperature-reaching time.

[0072] Among them, when the second difference is greater than or equal to the second preset value, it means that the actual temperature reaching time is greater than or equal to the first temperature reaching time, and then it can be determined that the actual temperature reaching time is greater than or equal to the first temperature reaching time, that is, the degree of dirtiness and clogging of the filter has reached the degree of dirtiness and clogging corresponding to the set dirtiness and clogging threshold.

[0073] In some embodiments, S400, determining a first temperature reaching time for the air conditioner to adjust the first indoor temperature to the first set temperature when the filter of the air conditioner reaches a set dirty and blocked threshold, includes:

[0074] S410, determining the dirty blocking cooling capacity / dirty blocking heating capacity of the air conditioner when the filter reaches a set dirty blocking threshold.

[0075] When the air conditioner is in heating mode, the dirty blocking heating capacity is determined; when the air conditioner is in cooling mode, the dirty blocking cooling capacity is determined.

[0076] Among them, different dirty blocking thresholds represent different degrees of filter blocking. Different degrees of filter blocking will have different degrees of influence on the cooling capacity / heating capacity of the air conditioner. Therefore, setting the dirty blocking threshold has a corresponding dirty blocking cooling capacity / dirty blocking heating capacity.

[0077] The dirty blocking cooling capacity / dirty blocking heating capacity corresponding to the set dirty blocking threshold can be determined through simulation software or preset parameters.

[0078] S420, determining the first temperature reaching time according to the dirty blockage cooling capacity / dirty blockage heating capacity.

[0079] Among them, determining the dirty blockage cooling capacity / dirty blockage heating capacity of the air conditioner is essentially to determine the specific impact of the dirty blockage of the air conditioner's filter on the air intake volume of the air conditioner. Under normal circumstances, the air intake volume will directly affect the cooling capacity / heating capacity of the air conditioner. After the air conditioner's filter is dirty and clogged, it will directly affect the air intake volume of the air conditioner, and then affect the cooling capacity / heating capacity of the air conditioner, thereby forming the dirty blockage cooling capacity / dirty blockage heating capacity; after determining the dirty blockage cooling capacity / dirty blockage heating capacity, the first temperature-reaching time can be determined according to the dirty blockage cooling capacity / dirty blockage heating capacity, temperature changes and indoor volume.

[0080] In some embodiments, S420, determining the first temperature reaching time according to the dirty blocking cooling capacity / dirty blocking heating capacity includes:

[0081] A first temperature difference is determined according to the first indoor temperature and the first set temperature.

[0082] Among them, the first indoor temperature is T 室1 , the first set temperature is T 设1 , the first temperature difference is ΔT1, ΔT1=|T 室1 -T 设1 |.

[0083] The first temperature reaching time is determined according to the first temperature difference, the indoor volume and the dirty blocking cooling capacity / dirty blocking heating capacity.

[0084] The indoor volume is the internal volume of the indoor environment where the air conditioner is currently located, which is generally the product of the indoor area of ​​the current indoor environment and the indoor height.

[0085] Among them, the first temperature difference is ΔT1, the indoor volume is V, and the dirty blockage cooling capacity / dirty blockage heating capacity is Q 脏堵 , the first temperature reaching time is t 脏堵 , Where a is a constant term, and the general value of a is 0.86.

[0086] Among them, a is generally the ratio of dirty blocking cooling capacity / dirty blocking heating capacity to effective cooling capacity / heating capacity.

[0087] In some embodiments, S410, determining the dirty blocking cooling capacity / dirty blocking heating capacity of the air conditioner when the filter reaches a set dirty blocking threshold, includes:

[0088] S411, determining the attenuation ratio of the cooling capacity / heating capacity of the air conditioner when the filter reaches a set dirty and blocked threshold.

[0089] Among them, different dirty blockage thresholds correspond to different attenuation ratios. The controller of the air conditioner stores multiple dirty blockage threshold ranges and attenuation ratios corresponding to each dirty blockage threshold range. That is, the attenuation ratio corresponding to the threshold can be determined by setting the dirty blockage range in which the dirty blockage threshold is located.

[0090] S412: Determine the dirty blocking cooling capacity / dirty blocking heating capacity according to the standard cooling capacity / standard heating capacity and the attenuation ratio of the air conditioner.

[0091] Among them, the decay ratio is b, and the standard cooling capacity / standard heating capacity is Q 标准 , i.e. dirty blockage cooling capacity / dirty blockage heating capacity Q 脏堵 =Q 标准 * b.

[0092] In some embodiments, S200, determining a theoretical temperature reaching time for the air conditioner to adjust the first indoor temperature to the first set temperature includes:

[0093] S210, determining a theoretical temperature-reaching time according to the standard cooling capacity / standard heating capacity of the air conditioner.

[0094] When the air conditioner is in heating mode, the standard heating capacity is determined; when the air conditioner is in cooling mode, the standard cooling capacity is determined.

[0095] Among them, the standard cooling capacity / standard heating capacity is actually the rated cooling capacity / rated heating capacity when the filter is not dirty or blocked; after determining the standard cooling capacity / standard heating capacity, the theoretical temperature reaching time can be determined based on the standard cooling capacity / standard heating capacity, temperature change and indoor volume.

[0096] In some embodiments, S210, determining the theoretical temperature reaching time according to the standard cooling capacity / standard heating capacity of the air conditioner includes:

[0097] S211, determining a first temperature difference according to the first indoor temperature and the first set temperature.

[0098] Among them, the first indoor temperature is T 室1 , the first set temperature is T 设1 , the first temperature difference is ΔT1, ΔT1=|T 室1 -T 设1 |.

[0099] The theoretical temperature-reaching time is determined according to the first temperature difference, the indoor volume and the standard cooling capacity / standard heating capacity.

[0100] Among them, the first temperature difference is ΔT1, the indoor volume is V, and the standard cooling capacity / standard heating capacity is Q 标准 , the theoretical temperature reaching time is t 理论 , Where a is a constant term, and the general value of a is 0.86.

[0101] Among them, a is generally the ratio of rated cooling capacity / rated heating capacity to effective cooling capacity / heating capacity.

[0102] In some embodiments, the present invention further provides a filter net dirty blockage monitoring device 10, comprising an acquisition module 100, a judgment module 200 and a calculation module 300. The acquisition module 100 is used to acquire the first indoor temperature, and acquire the actual temperature reaching time when the air conditioner adjusts the first indoor temperature to the first set temperature after the air conditioner is started. The judgment module 200 is used to determine that the filter net is dirty and blocked after determining that the actual temperature reaching time is greater than the theoretical temperature reaching time. The calculation module 300 is used to determine the theoretical temperature reaching time when the air conditioner adjusts the first indoor temperature to the first set temperature.
