Among them, the storage of some fruits and vegetables (such as lychees, strawberries, bananas, etc.) is more sensitive to temperature. Therefore, for the storage of temperature-sensitive fruits and vegetables, the cooling capacity of the air conditioner in the cold storage needs to be accurately controlled.

[0071] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0072] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0073] like Figure 1 As shown, it is a schematic diagram of an indoor environment in which an air conditioner is located, for example, a plurality of different positions of a cold storage, in which corresponding temperature sensors are respectively arranged. For the cold storage 101, corresponding temperature sensors are respectively arranged at 6 different positions therein. It should be noted that the setting position of the temperature sensor can be adjusted according to actual needs, and the embodiment of the present application does not limit this.

[0074] Specifically, a corresponding temperature sensor 102 is set at the rear upper left corner of the cold storage, a corresponding temperature sensor 103 is set at the rear lower right corner of the cold storage, a corresponding temperature sensor 104 is set at the middle upper left position of the cold storage, a corresponding temperature sensor 105 is set at the middle upper right position of the cold storage, a corresponding temperature sensor 106 is set at the front upper left corner of the cold storage, and a corresponding temperature sensor 107 is set at the front lower right corner of the cold storage.

[0075] In this way, after setting the corresponding temperature sensors at various positions, the relative temperature range values ​​corresponding to each position can be determined, and the temperatures collected by the temperature sensors at each position can be obtained. By using the temperatures and relative temperature range values ​​of multiple different positions in the indoor environment, the indoor temperature corresponding to the indoor environment can be obtained, which can reduce the deviation from the actual indoor temperature, thereby improving the precise control of the cooling capacity of the air conditioner and achieving effective control of the indoor temperature of the indoor environment.

[0076] Based on the above invention concept, Figure 2 FIG. 1 is a schematic diagram of an implementation flow of an air conditioning control method provided in an embodiment of the present application. The method is applied to an air conditioner and may specifically include the following steps:

[0077] S201, determining the relative temperature extreme value corresponding to each position, and obtaining the current temperature collected by the temperature sensor at each position.

[0078] In the embodiment of the present application, for different positions of the indoor environment where the air conditioner is located, it is necessary to determine the temperature relative extreme difference value corresponding to each position. Figure 1 As shown, for the 6 different positions of the cold storage where the air conditioner is located, it is necessary to determine the relative temperature range value corresponding to each position.

[0079] It should be noted that the premise for determining the relative temperature extreme value corresponding to each position is that the indoor environment is kept at a constant temperature, which means that during the process of maintaining the indoor environment at a constant temperature, the relative temperature extreme value corresponding to each position is determined. This embodiment of the present application does not limit this.

[0080] In addition, in the embodiment of the present application, it is also necessary to obtain the current temperature collected by the temperature sensors at each location. Figure 1 As shown, for the temperature sensors at 6 different positions, the current temperatures collected by the temperature sensors at each position are obtained, namely, T1 to T6.

[0081] S202: Determine the indoor temperature corresponding to the indoor environment according to the current temperature and the relative temperature extreme value.

[0082] In the embodiment of the present application, for the temperature relative extreme values ​​corresponding to each position determined in the above steps, and the current temperatures collected by the temperature sensors at each position, the indoor temperature corresponding to the indoor environment can be determined based on these temperature relative extreme values ​​and the current temperature. Among them, the indoor temperature can be understood as the overall temperature of the indoor environment.

[0083] For example, the relative temperature range values ​​corresponding to each position determined in the above steps, i.e., R1~R6, and the current temperatures collected by the temperature sensors at each position, i.e., T1~T6, are used to determine the indoor temperature T of the cold storage based on the relative temperature range values ​​R1~R6 and the current temperatures T1~T6, that is, to determine the overall temperature of the cold storage based on the relative temperature range values ​​R1~R6 and the current temperatures T1~T6.

[0084] S203, comparing the indoor temperature with the target indoor temperature, and controlling the air conditioner according to the comparison result.

[0085] In the embodiment of the present application, after the indoor temperature of the indoor environment is determined, the indoor temperature can be compared with the target indoor temperature (ie, the set indoor temperature of the indoor environment), and the air conditioner can be controlled according to the comparison result.

[0086] Specifically, when the temperature difference between the indoor temperature and the target indoor temperature is less than or equal to the preset first temperature difference threshold, and the duration is greater than the preset first duration, it means that the indoor temperature of the indoor environment is generally low. At this time, the air conditioner is controlled to reduce the cooling capacity to increase the indoor temperature of the indoor environment.

[0087] For example, when the temperature difference ΔT≤-1°C between the indoor temperature and the target indoor temperature and the duration T>T0 (for example, T0 is 10 seconds), it indicates that the overall indoor temperature of the cold storage is low. At this time, the cold storage air conditioner is controlled to reduce the cooling capacity and increase the indoor temperature of the cold storage.

[0088] In addition, when the temperature difference between the indoor temperature and the target indoor temperature is greater than or equal to the preset second temperature difference threshold, and the duration is greater than the preset second duration, it means that the overall indoor temperature of the indoor environment is too high. At this time, the air conditioner is controlled to increase the cooling capacity to lower the indoor temperature of the indoor environment.

[0089] For example, when the temperature difference ΔT between the indoor temperature and the target indoor temperature is ≥1°C and lasts for T>T0 (for example, T0 is 10 seconds), it means that the overall indoor temperature of the cold storage is too high. At this time, the cold storage air conditioner is controlled to increase the cooling capacity to lower the indoor temperature of the cold storage.

[0090] Through the above description of the technical solution provided in the embodiment of the present application, corresponding temperature sensors are respectively set at multiple different positions of the indoor environment where the air conditioner is located, the relative temperature extreme value corresponding to each position is determined, and the current temperature collected by the temperature sensor at each position is obtained. According to the current temperature and the relative temperature extreme value, the indoor temperature corresponding to the indoor environment is determined, the indoor temperature is compared with the target indoor temperature, and the air conditioner is controlled according to the comparison result.

[0091] By respectively setting corresponding temperature sensors at multiple different positions of the indoor environment where the air conditioner is located, the indoor temperature corresponding to the indoor environment is determined according to the current temperature collected by the temperature sensors at each position and the temperature relative extreme value corresponding to each position, and compared with the target indoor temperature, so as to control the air conditioner according to the comparison result. In this way, the indoor temperature corresponding to the indoor environment is obtained through the temperatures and temperature relative extreme values ​​at multiple different positions of the indoor environment, which can reduce the deviation from the actual indoor temperature, thereby improving the precise control of the cooling capacity of the air conditioner and realizing effective control of the indoor temperature of the indoor environment.

[0092] like Figure 3 FIG. 1 is a schematic diagram of an implementation flow of another air conditioning control method provided in an embodiment of the present application. The method is applied to an air conditioner and may specifically include the following steps:

[0093] S301, for any location, obtaining a plurality of first temperatures collected by a temperature sensor at the location within a preset first time period.

[0094] S302, determining the temperature relative extreme difference value corresponding to the position according to the multiple first temperatures, and obtaining the current temperature collected by the temperature sensors at the respective positions.

[0095] In the embodiment of the present application, corresponding temperature sensors are respectively set at different positions of the indoor environment where the air conditioner is located. For this purpose, for any position, multiple first temperatures collected by the temperature sensor at the position are obtained within a preset first time period, and the relative temperature range value corresponding to the position is determined based on the multiple first temperatures. In addition, it is also necessary to obtain the current temperature collected by the temperature sensors at each position.

[0096] It should be noted that for a temperature sensor at any position, it can collect temperature according to a set temperature collection frequency, for example, collecting temperature once every 6 minutes, so that 10 first temperatures can be collected within 1 hour, and the embodiment of the present application is not limited to this.

[0097] Among them, for the above-mentioned multiple first temperatures, the average temperature of the multiple first temperatures can be obtained, and the first maximum temperature and the first minimum temperature can be selected from the multiple first temperatures, and the temperature relative extreme value corresponding to the position can be determined according to the average temperature, the first maximum temperature and the first minimum temperature. In this way, the temperature relative extreme value corresponding to each position qualification is determined.

[0098] Specifically, a first temperature difference between a first maximum temperature and a first minimum temperature may be obtained; the first temperature difference is divided by the average temperature to obtain a relative temperature extreme value corresponding to the position.

[0099] For example, for any location, 10 first temperatures collected by the temperature sensor at the location can be obtained within 1 hour, and the average temperature T of the 10 first temperatures can be obtained. 平均 , and then select the first maximum temperature T from these 10 first temperatures max and the first minimum temperature T min , then the average temperature T 平均 , the first maximum temperature T max、 The first minimum temperature T min Substitute the following formula to calculate the relative temperature range R at that location.

[0100]

[0101] S303, determining the coupled temperature control weights corresponding to the respective positions according to the relative temperature extreme values.

[0102] In the embodiment of the present application, after the above steps, the relative temperature extreme value corresponding to each position can be calculated, and the coupling temperature control weight corresponding to each position can be determined according to the relative temperature extreme value.

[0103] Among them, the temperature relative extreme difference values ​​corresponding to each position can be added to obtain the sum of the temperature relative extreme difference values. Therefore, for any position, the temperature relative extreme difference value corresponding to the position is divided by the sum of the temperature relative extreme difference values ​​to obtain the coupling temperature control weight corresponding to the position.

[0104] For example, the temperature relative extreme difference values ​​R1 to R6 corresponding to each position can be added to obtain the sum of the temperature relative extreme difference values. Therefore, for any position, the temperature relative extreme difference value corresponding to the position is divided by the sum of the temperature relative extreme difference values ​​to obtain the coupling temperature control weight C corresponding to the position, as shown in the following formula.

[0105]

[0106] S304: Determine the indoor temperature corresponding to the indoor environment according to the current temperature and the coupled temperature control weight.

[0107] In an embodiment of the present application, after the above steps, the coupled temperature control weight corresponding to each position and the current temperature collected by the temperature sensor at each position can be obtained, thereby determining the indoor temperature corresponding to the indoor environment based on the current temperature and the coupled temperature control weight.

[0108] Among them, the coupled temperature control weights corresponding to each position and the current temperature collected by the temperature sensor at each position can be weighted summed to obtain the indoor temperature corresponding to the indoor environment.

[0109] For example, the coupled temperature control weights C1-C6 corresponding to each position and the current temperatures T1-T6 collected by the temperature sensors at each position may be weighted summed to obtain the indoor temperature T corresponding to the indoor environment, as shown in the following formula.

[0110] T=T1*C1+T2*C2+T3*C3+T4*C4+T5*C5+T6*C6.

[0111] S305, comparing the indoor temperature with the target indoor temperature, and controlling the air conditioner according to the comparison result.

[0112] In the embodiment of the present application, this step is similar to the above-mentioned step S203, and the embodiment of the present application will not be described one by one here.

[0113] By respectively setting corresponding temperature sensors at multiple different positions of the indoor environment where the air conditioner is located, the indoor temperature corresponding to the indoor environment is determined according to the current temperature collected by the temperature sensors at each position and the temperature relative extreme value corresponding to each position, and compared with the target indoor temperature, so as to control the air conditioner according to the comparison result. In this way, the indoor temperature corresponding to the indoor environment is obtained through the temperatures and temperature relative extreme values ​​at multiple different positions of the indoor environment, which can reduce the deviation from the actual indoor temperature, thereby improving the precise control of the cooling capacity of the air conditioner and realizing effective control of the indoor temperature of the indoor environment.

[0114] In addition, for the indoor environment, the overall heat load will gradually decrease, and the indoor temperature will drop overall. However, when the door is suddenly opened, the heat load will increase suddenly. To ensure that the air conditioner can adapt to the sudden change in heat load, the temperature at each point in the indoor environment changes slowly due to the latent heat of the goods. Therefore, the indoor temperature changes slowly, and further correction of the indoor temperature is required.

[0115] For example, during the operation of the cold storage, the overall heat load will gradually decrease, and the indoor temperature of the cold storage will gradually drop. However, when the door is suddenly opened, the heat load will suddenly increase. In order to ensure that the cold storage air conditioner can adapt to the sudden change of heat load, the temperature of each point in the cold storage changes slowly due to the latent heat of the goods, so the indoor temperature of the cold storage changes slowly, so the indoor temperature needs to be further corrected.

[0116] Based on this, Figure 4 FIG. 1 is a schematic diagram of an implementation flow of another air conditioning control method provided in an embodiment of the present application. The method is applied to an air conditioner and may specifically include the following steps:

[0117] S401, for any location, obtaining a plurality of first temperatures collected by a temperature sensor at the location within a preset first time period.

[0118] In the embodiment of the present application, this step is similar to the above-mentioned step S301, and the embodiment of the present application will not be described one by one here.

[0119] S402, determining the temperature relative extreme difference value corresponding to the position according to the multiple first temperatures, and obtaining the current temperature collected by the temperature sensor at each position.

[0120] In the embodiment of the present application, this step is similar to the above-mentioned step S302, and the embodiment of the present application will not be described one by one here.

[0121] S403, determining the coupled temperature control weights corresponding to the respective positions according to the relative temperature extreme values.

[0122] In the embodiment of the present application, this step is similar to the above step S303, and the embodiment of the present application will not be described one by one here.

[0123] S404, determining the coupled temperature control correction coefficient corresponding to each position.

[0124] In the embodiment of the present application, for different positions of the indoor environment, the corresponding coupled temperature control correction coefficients are determined for each position to cope with the sudden change of the indoor environment heat load. Among them, the coupled temperature control correction coefficient is related to the change of the superheat of the evaporator of the air conditioner and the temperature of each position.

[0125] Based on this, for any position, multiple second temperatures collected by the temperature sensor at the position are obtained within the preset second time period; multiple superheats of the air conditioner evaporator are obtained within the preset second time period; based on the multiple second temperatures and multiple superheats, the coupled temperature control correction coefficient corresponding to the position is determined.

[0126] It should be noted that for the temperature sensor at any position, it can collect temperature according to the set temperature collection frequency, for example, collect temperature once every 6 minutes, so that 10 second temperatures can be collected within 1 hour, and the embodiment of the present application is not limited to this.

[0127] Among them, for the above-mentioned multiple second temperatures, the second maximum temperature and the second minimum temperature can be selected from the multiple second temperatures, and the maximum superheat and the minimum superheat can be selected from the multiple superheats. According to the second maximum temperature, the second minimum temperature, the maximum superheat and the minimum superheat, the coupling temperature control correction coefficient corresponding to the position is determined.

[0128] Specifically, the second temperature difference between the second maximum temperature and the second minimum temperature, and the superheat difference between the maximum superheat and the minimum superheat are obtained; the second temperature difference is divided by the superheat difference to obtain the coupled temperature control correction coefficient corresponding to the position.

[0129] For example, get the second maximum temperature T max With the second minimum temperature T min The second temperature difference between max and minimum superheat Ek min The superheat difference between the second temperature difference and the superheat difference are divided to obtain the coupling temperature control correction coefficient K corresponding to the position, as shown in the following formula.

[0130]

[0131] In addition, in the embodiment of the present application, the coupled temperature control correction coefficient is related to the superheat requirement of the object stored in the indoor environment and the temperature of each position. Based on this, for any position, multiple second temperatures collected by the temperature sensor of the position are obtained within a preset second time period, the maximum superheat and the minimum superheat corresponding to the object stored in the indoor environment are obtained, and the coupled temperature control correction coefficient corresponding to the position is determined according to the multiple second temperatures, the maximum superheat and the minimum superheat.

[0132] It should be noted that for the temperature sensor at any position, it can collect temperature according to the set temperature collection frequency, for example, collect temperature once every 6 minutes, so that 10 second temperatures can be collected within 1 hour, and the embodiment of the present application is not limited to this.

[0133] Among them, for the above-mentioned multiple second temperatures, the second maximum temperature and the second minimum temperature can be selected from the multiple second temperatures, and the coupled temperature control correction coefficient corresponding to the position can be determined according to the second maximum temperature, the second minimum temperature, the maximum superheat and the minimum superheat.

[0134] Specifically, the second temperature difference between the second maximum temperature and the second minimum temperature, and the superheat difference between the maximum superheat and the minimum superheat are obtained; the second temperature difference is divided by the superheat difference to obtain the coupled temperature control correction coefficient corresponding to the position.

[0135] S405: Determine the indoor temperature corresponding to the indoor environment according to the current temperature, the coupled temperature control weight, and the coupled temperature control correction coefficient.

[0136] In an embodiment of the present application, after the above steps, the coupled temperature control weight corresponding to each position, the coupled temperature control correction coefficient corresponding to each position, and the current temperature collected by the temperature sensor at each position can be obtained, thereby determining the indoor temperature corresponding to the indoor environment based on the current temperature, the coupled temperature control weight and the coupled temperature control correction coefficient.

[0137] Among them, the coupled temperature control weight corresponding to each position, the coupled temperature control correction coefficient corresponding to each position, and the current temperature collected by the temperature sensor at each position can be weighted summed to obtain the indoor temperature corresponding to the indoor environment.

[0138] For example, the coupled temperature control weights C1~C6 corresponding to each position, the coupled temperature control correction coefficients K1~K6 corresponding to each position, and the current temperatures T1~T6 collected by the temperature sensors at each position can be weighted summed to obtain the indoor temperature T corresponding to the indoor environment, as shown in the following formula.

[0139] T=T1*C1*K1+T2*C2+K2+T3*C3*K3+T4*C4*K4+T5*C5*K5+T6*C6*K6.

[0140] S406, comparing the indoor temperature with the target indoor temperature, and controlling the air conditioner according to the comparison result.

[0141] In the embodiment of the present application, this step is similar to the above-mentioned step S203, and the embodiment of the present application will not be described one by one here.

[0142] By respectively setting corresponding temperature sensors at multiple different positions of the indoor environment where the air conditioner is located, the indoor temperature corresponding to the indoor environment is determined according to the current temperature collected by the temperature sensors at each position, the coupled temperature control weights corresponding to each position, and the coupled temperature control correction coefficients corresponding to each position, and compared with the target indoor temperature, so as to control the air conditioner according to the comparison result. In this way, the indoor temperature corresponding to the indoor environment is obtained through the temperatures, coupled temperature control weights and coupled temperature control correction coefficients at multiple different positions of the indoor environment, which can reduce the deviation from the actual indoor temperature, thereby improving the precise control of the cooling capacity of the air conditioner, realizing effective control of the indoor temperature of the indoor environment, and can also cope with the sudden change of the heat load of the indoor environment.

[0143] The following takes the indoor environment as a cold storage as an example to illustrate the air conditioning control method provided by the embodiment of the present application: For the cold storage, corresponding temperature sensors are respectively set at 6 different positions of the cold storage, such as Figure 1 As shown, by analyzing the temperature at 6 different positions of the cold storage, the indoor temperature of the cold storage is obtained, thereby controlling the cooling capacity of the cold storage air conditioner and achieving effective temperature control of the cold storage.

[0144] When the cold storage is in the process of constant temperature, the temperature sensors at various positions start to detect and record the temperature data regularly. For example, the time set in the embodiment of the present application is 6 minutes to record once. After recording 10 groups of temperature data (i.e. 1 hour), each group of temperature data is analyzed, that is, the range calculation method is used to obtain the relative range value R of the temperature at each position, which satisfies the following formula:

[0145]

[0146] Among them, R is the relative temperature range, T max is the maximum temperature measurement value, T min is the minimum temperature measurement value, T 平均 is the average value of temperature measurements.

[0147] After the relative temperature extreme value of each position is obtained, the coupled temperature control weight of each position is calculated, wherein for each position, the corresponding coupled temperature control weight C is calculated using the following formula.

[0148]

[0149] After calculating the coupled temperature control weights of each location, the indoor temperature of the cold storage can be calculated by the coupled control calculation method to meet the following formula:

[0150] T=T1*C1+T2*C2+T3*C3+T4*C4+T5*C5+T6*C6.

[0151] Among them, Cn represents the coupled temperature control weight of each position, Tn represents the real-time temperature detected by the temperature sensor at each position, and n is 1, 2, 3, 4, 5, and 6 respectively.

[0152] At the same time, during the operation of the cold storage, the overall heat load will gradually decrease, and the indoor temperature of the cold storage will gradually decrease. However, when the door is suddenly opened, resulting in a sudden increase in heat load, in order to ensure that the cold storage air conditioner can adapt to the sudden change in heat load, the temperature at each point in the cold storage changes slowly due to the latent heat of the goods at this time, so the indoor temperature of the cold storage changes slowly, and the indoor temperature T of the cold storage needs to be further corrected. According to the real-time operating parameters of the cold storage, the evaporator superheat change Ek of the cold storage air conditioner can be collected to calculate the coupled temperature control correction coefficient to meet the following formula:

[0153]

[0154] Then the indoor temperature T of the cold storage is corrected according to the coupled temperature control correction coefficient K as follows:

[0155] T=T1*C1*K1+T2*C2+K2+T3*C3*K3+T4*C4*K4+T5*C5*K5+T6*C6*K6.

[0156] After the indoor temperature of the cold storage is calculated, it is compared with the set indoor temperature. When it is found that the difference between the indoor temperature of the cold storage and the set indoor temperature is ΔT≤-1°C, and the time T>T0 (for example, T0 is 10s), it means that the indoor temperature of the cold storage is low. In this case, the air conditioner of the cold storage is controlled to reduce the cooling capacity and increase the indoor temperature of the cold storage.

[0157] With the continuous constant temperature operation of the cold storage and the regular detection of the temperature sensor, when it is found that the difference between the indoor temperature of the cold storage and the set indoor temperature is ΔT≥1°C, and the time T>T0 (for example, T0 is 10s), it means that the indoor temperature of the cold storage is too high. In this case, the air conditioner of the cold storage is controlled to increase the cooling capacity and lower the indoor temperature of the cold storage.

[0158] In this way, the indoor temperature of the cold storage can be obtained by measuring the temperatures at multiple different locations of the cold storage, the coupled temperature control weights and the coupled temperature control correction coefficients. This can reduce the deviation from the actual indoor temperature, thereby improving the precise control of the cooling capacity of the air conditioner, achieving effective control of the indoor temperature of the cold storage, and also coping with sudden changes in the heat load of the cold storage.
