Description

Technical Field

[0001] This invention relates to the field of air conditioning control technology, specifically to a ducted air conditioning control method, a ducted air conditioning unit, and a readable storage medium. Background Technology

[0002] In a current ducted air conditioning control method, to ensure the compressor frequency better meets the needs of each room, the method includes, after the outdoor unit starts and runs for at least a first set time, acquiring the indoor unit operating parameters and indoor environmental parameters of each indoor unit. The indoor unit operating parameters include the indoor unit's preset frequency, preset temperature value, and preset fan speed. Then, based on the indoor unit operating parameters and indoor environmental parameters, a target frequency for each indoor unit is determined. Specifically, a second temperature coefficient for each indoor unit is obtained based on the temperature difference between the preset temperature value and the indoor ambient temperature; a second fan speed coefficient for each indoor unit is obtained based on the preset fan speed; and the target frequency of the indoor unit is obtained by multiplying the preset frequency, the second temperature coefficient, and the second fan speed coefficient. Finally, the outdoor environmental parameters of the outdoor unit are acquired, and based on these parameters and the target frequency of each indoor unit, the target compressor frequency of the outdoor unit is determined, and the compressor is adjusted based on the target compressor frequency.

[0003] However, the existing ducted air conditioning control method still fails to meet the actual cooling / heating needs of each room. Summary of the Invention

[0004] The primary objective of this invention is to provide a ducted air conditioning control method that better meets the actual cooling / heating needs of each room by controlling the compressor power.

[0005] The second objective of this invention is to provide a ducted air conditioner capable of implementing the above-described ducted air conditioner control method.

[0006] A third objective of this invention is to provide a readable storage medium capable of implementing the above-described ducted air conditioning control method.

[0007] The first objective of this invention is to provide a ducted air conditioning control method comprising: acquiring the detected temperature value, preset temperature value, outdoor temperature value, and preset area of ​​each operating room; determining a first coefficient for each operating room based on the detected temperature value and preset temperature value, and calculating the required area of ​​each operating room based on the first coefficient and the preset area; calculating a second coefficient based on the sum of the required areas of each operating room and the total area of ​​all rooms, and calculating the target frequency of the compressor based on the second coefficient and a preset upper limit value of the compressor frequency; and controlling the compressor to operate according to the target frequency.

[0008] As can be seen from the above solutions, the reason why the background technology failed to meet the actual cooling / heating needs of each room is that it did not consider the different room sizes and varying demand when calculating the compressor target power, and it did not consider the impact of unused rooms on the total actual demand. The control method of this invention calculates the second coefficient based on the relationship between the area of ​​each used room and the total area of ​​all rooms. In particular, when determining the area of ​​each room, it combines the relationship between the detected temperature value of each used room and the preset temperature value to generate a required area value that meets the actual needs. Then, it calculates the second coefficient by combining the sum of the required areas of each room with the total area of ​​all rooms, and combines the second coefficient with the compressor's upper frequency limit to calculate the target frequency. This method not only considers the relationship between the size of each used room and the demand, but also the difference between the current detected temperature and the set temperature, which also affects the demand. Therefore, it corrects the set area calculation to ensure that the required area, the second coefficient, and the finally calculated compressor target frequency meet the cooling / heating needs of each used room.

[0009] A further approach involves the following steps in calculating the target frequency of the compressor based on the second coefficient and a preset upper limit value for the compressor frequency: generating a first frequency based on the product of the second coefficient and the preset upper limit value for the compressor, and generating the target frequency based on the first frequency.

[0010] As can be seen above, the second coefficient reflects the ratio of the required area to the total area of ​​all rooms. The first frequency is generated by multiplying the second coefficient by the preset upper limit of frequency. The target frequency is then calculated based on the first frequency to meet the cooling / heating needs of each room that is turned on.

[0011] A further approach is that, if the currently calculated target frequency is the initial target frequency after the compressor is turned on, in the step of generating the target frequency based on the first frequency: the second frequency is calculated based on the first frequency and the first preset value; if the second frequency is less than the upper limit value of the frequency, the second frequency is used as the initial target frequency; if the second frequency is greater than or equal to the upper limit value of the frequency, the upper limit value of the frequency is used as the target frequency.

[0012] As can be seen above, the recommended range for the first preset value is 2~10Hz. During the initial startup phase, to achieve rapid cooling and heating, an additional correction coefficient (first preset value) can be added. When the second frequency is greater than or equal to the upper frequency limit, it indicates that a large number of rooms require air conditioning, resulting in a high demand for cooling and heating. However, to ensure overall system reliability, the compressor's target frequency cannot exceed its upper frequency limit at this time; in this case, the upper frequency limit is used as the target frequency. Conversely, if the second frequency is less than the upper frequency limit, it indicates that a smaller number of rooms require air conditioning, resulting in a lower demand for cooling and heating. In this case, the target frequency can be calculated based on the area (second frequency).

[0013] A further approach is to update the target frequency when the compressor's runtime is greater than or equal to a second preset value; if the current step is a target frequency update calculation step, in the step of generating the target frequency based on the first frequency: calculate the current second frequency; determine whether the difference between the second frequency before and after the runtime is greater than or equal to a third preset value; if so, use the current first frequency as the updated target frequency.

[0014] A further approach is to use the current second frequency as the updated target frequency when the difference between the second and third frequencies before and after the confirmed runtime is less than the third preset value.

[0015] As can be seen above, the compressor's target frequency is updated periodically, and the second frequency is recalculated based on the current data. However, the second frequency is not directly used as the target frequency after calculation. Instead, the difference between the current second frequency and the initial target frequency is used to determine whether each room has achieved effective temperature regulation during the operating period. If the difference between the initial target frequency and the second frequency is greater than or equal to the third preset value, it indicates that the room temperature is dropping rapidly, and the compressor's target frequency is decreasing rapidly. To achieve energy saving, the rapid cooling / heating mode can be exited, and there is no need to add the correction coefficient of the first preset value when calculating the compressor frequency. Therefore, the current first frequency is used as the updated target frequency. Conversely, if rapid cooling / heating is still needed, the second frequency plus the first preset value is used as the target frequency.

[0016] Another further approach is to include, in the step of calculating the first coefficient for each operating room based on the detected temperature value and the preset temperature value, determining the value of the first coefficient based on the numerical range of the ratio of the detected temperature value to the preset temperature value.

[0017] As can be seen from the above, since the ratio of the detected temperature value to the preset temperature value is not directly related to the ratio of the required area to the preset area, in the step of calculating the first coefficient for each operating room using the detected temperature value and the preset temperature value, this invention does not directly use the ratio of the detected temperature value to the preset temperature value as the settlement result, but determines the value of the first coefficient based on the numerical range of the ratio. Under this calculation, the demand of each operating room is categorized into levels, and the first coefficient is determined by the reasonable values ​​corresponding to each preset demand level, which facilitates the matching degree between the calculation result and the room's cooling / heating demand.

[0018] A further step is to determine the value of the first coefficient based on the range of the ratio of the detected temperature value to the preset temperature value. This includes the following steps if the air conditioner is in cooling operation: when the ratio of the detected temperature value to the preset temperature value in a room is less than or equal to a first preset ratio, the first coefficient is assigned a preset first value; when the ratio of the detected temperature value to the preset temperature value in a room is greater than the first preset ratio but less than or equal to a first calculated value, the first coefficient is assigned a preset second value; the first calculated value is the ratio of the sum of the preset temperature value and the fourth preset value to the preset temperature value; when the ratio of the detected temperature value to the preset temperature value in a room is greater than the first calculated value, the first coefficient is the ratio of the detected temperature value to the preset temperature value.

[0019] A further step is to determine the value of the first coefficient based on the range of the ratio of the detected temperature value to the preset temperature value. This includes the following steps if the air conditioner is in heating mode: when the ratio of the detected temperature value to the preset temperature value of a room is greater than or equal to a second preset ratio, the first coefficient is assigned a preset third value; when the ratio of the detected temperature value to the preset temperature value of a room is less than the second preset ratio but greater than or equal to a second calculated value, the first coefficient is assigned a preset fourth value; the second calculated value is the ratio of the difference between the preset temperature value and the fifth preset value to the preset temperature value; when the ratio of the detected temperature value to the preset temperature value of a room is less than the second calculated value, the first coefficient is the ratio of the detected temperature value to the preset temperature value.

[0020] As can be seen above, depending on the cooling mode and heating module, the first coefficient corresponding to the range of values ​​for the ratio of the detected temperature value to the preset temperature value is different. This setting ensures that a more accurate first coefficient can be determined in both cooling and heating modes. Taking cooling mode as an example, when the detected temperature value is less than the second preset value, it means that the current ambient temperature is lower than or equal to the set temperature, indicating that the room does not require additional cooling, and the first coefficient takes the smaller preset first value. If the ratio of the detected temperature value to the preset temperature value is greater than the first preset ratio but less than or equal to the first calculated value, the ambient temperature is higher than the set temperature, but the difference between the ambient temperature and the set temperature is small, indicating that the room does not require significant cooling, and the compressor frequency can be calculated normally based on the area, and the first coefficient takes the larger preset second value. Otherwise, it means that the ambient temperature is higher than the set temperature, and the difference between the ambient temperature and the set temperature is large, indicating that the room requires significant cooling, and an additional correction system is needed to calculate the compressor frequency to achieve rapid cooling.

[0021] The second objective of this invention is to provide a ducted air conditioner that includes a processor, which executes a computer program stored in a memory to implement the above-described ducted air conditioner control method.

[0022] The third objective of this invention is to provide a readable storage medium on which a computer program is stored, which, when executed by a processor, implements the ducted air conditioning control method described above. Attached Figure Description

[0027] Figure 5 This is the fourth flowchart of an embodiment of the ducted air conditioning control method of the present invention. Detailed Implementation

[0028] Examples of Ductless Air Conditioning Systems and Control Methods See Figure 1 The ducted air conditioner in this embodiment is a ducted air conditioner, which includes an outdoor unit (not shown) and an indoor unit 91. The indoor unit 91 has a main board 911 for calculating and storing data. The indoor unit 91 can be connected to one or more main air ducts and supply air to multiple rooms. Figure 1 The indoor unit 91 and two main air ducts 92 are shown. Each main air duct 92 supplies air to four rooms respectively, so the indoor unit 91 can supply air to at least eight rooms through the main air ducts 92.

[0029] Each room is equipped with an air valve, and the eight rooms are each equipped with air valves A through H. The air valves are capable of detecting and acquiring the ambient room temperature (the temperature value detected by this invention), and the room temperature of each room can be set independently.

[0030] In this embodiment, air valves A through H are all connected to area controller 1, which is connected to main board 911. The detected temperature values ​​from air valves A through H, as well as the set temperature values ​​for each room, can be transmitted from area controller 1 to main board 911. The outdoor unit is a variable frequency unit with speed control functionality.

[0031] In other embodiments, if the total number of rooms is small, area controllers may not be required, and the air valves in each room are connected to the main board of the indoor unit.

[0032] The motherboard 911 includes a processor, which executes a computer program stored in the memory to implement the ducted air conditioning control method of the present invention. The processor can be a Central Processing Unit (CPU), or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or any conventional processor.

[0033] The ducted air conditioner also includes a memory, which mainly comprises a program storage area and a data storage area. The program storage area can store the operating system and at least one application program required for a given function (such as sound playback or image playback). The data storage area can store data created based on the use of the handheld terminal (such as audio data or a phone book). Furthermore, the memory can include high-speed random access memory and non-volatile memory, such as hard disks, RAM, plug-in hard disks, smart media cards (SMC), secure digital cards (SD cards), flash cards, at least one disk storage device, flash memory device, or other volatile solid-state storage devices.

[0034] Before implementing the ducted air conditioning control method of the present invention, the following setup steps are performed: connect each room's air valves A to H to the area controller 1, and input the room area corresponding to each air valve.

[0035] Each room's air valve is connected to area controller 1 and corresponds to the area controller's number. For example, air valve A in room 1 corresponds to interface A of the area controller, air valve B in room 2 corresponds to interface B of the area controller, and so on.

[0036] Simultaneously, the actual area of ​​each room is input into the corresponding parameters of the corresponding area controller interface, and used as the preset area for calculation in the control method of this invention. This operation facilitates the subsequent detection of the rooms being operated by the area controller and the calculation of the compressor frequency based on the cooling capacity requirements of each room.

[0037] The air conditioning control method for ducted air conditioners of the present invention includes: First, execute step S1 to start the ducted air conditioning unit.

[0038] Then, step S2 is executed to detect the indoor and outdoor ambient temperatures. This step prepares for subsequent determination of the compressor frequency upper limit.

[0039] Then, step S3 is executed to determine the upper limit of the compressor frequency based on the detected indoor and outdoor ambient temperatures.

[0040] The ducted air conditioner's program has its upper frequency limit determined before leaving the factory based on performance and reliability requirements under different indoor and outdoor ambient temperatures. The compressor's upper frequency limit is primarily determined by the declared maximum permissible usable area and can be determined by referring to a table. max .

[0041] Then, step S4 is executed to obtain the detected temperature value Tx and the preset temperature value T for each powered-on room. 设x And a preset area Sx, where x represents the serial number of the room where the unit is turned on. By detecting the area of ​​the room where the unit is turned on, the ambient temperature, and the set temperature, preparation is made for calculating the target frequency of the compressor using a calculation formula.

[0042] Then, step S5 is executed to calculate the detected temperature value Tx and the preset temperature value T for each powered-on room. 设x The ratio of . Next, the step of calculating the first coefficient for each operating room based on the detected temperature value and the preset temperature value is performed. Further, the step of confirming the value of the first coefficient based on the numerical range of the ratio of the detected temperature value to the preset temperature value is performed.

[0043] Combination Figure 3 If the current operating mode is cooling mode, proceed to step S6 after step S5 to determine Tx / T. 设X ≤1, meaning the detected temperature value Tx of each powered-on room is compared to the preset temperature value T. 设x The ratio is less than or equal to the first preset ratio, which is 1.

[0044] If the result of step S6 is yes, then proceed to step S8, Tx / T 设X =0, Tx / T 设X As the first coefficient, the first coefficient takes a preset first value, which is 0 in this embodiment.

[0045] In this case, if the indoor ambient temperature is lower than or equal to the set temperature, it means that the room does not require additional cooling.

[0046] If the result of step S6 is negative, then proceed to step S7 to determine whether 1 < Tx / T is satisfied. 设X ≤(T 设X+2) / T 设X That is, to determine the difference between the detected temperature value Tx of a certain room that is turned on and the preset temperature value T. 设X The ratio is greater than the first preset ratio 1 and less than or equal to the first calculated value, the first calculated value (T) 设X +2) / T 设X Preset temperature value T 设X The sum of the fourth preset value and the preset temperature value T 设X The ratio of .

[0047] The first calculated value is set to determine whether the detected temperature value Tx is different from the preset temperature value T. 设X The fourth preset value is set higher. For example, in this embodiment, the fourth preset value is 2. If the temperature value is set to 20, it is determined whether the current detected temperature value is 2 degrees higher than 20 degrees, that is, whether the detected temperature value is higher than 22 degrees.

[0048] If the result of step S7 is yes, then proceed to step S9, Tx / T 设X As the first coefficient, the first coefficient takes a preset second value. In this embodiment, the second value is 1.

[0049] At this time, the ambient temperature is higher than the set temperature, but the difference between the ambient temperature and the set temperature is small, indicating that this room does not require a large amount of cooling, and the compressor frequency can be calculated normally according to the preset area (actual area).

[0050] If the result of step S7 is negative, then step S10 is executed. At this time, the detected temperature value Tx of the room is compared with the preset temperature value T. 设X The ratio is greater than the first calculated value (T) 设X +2) / T 设X At this point, the first coefficient is taken as the ratio of the detected temperature value to the preset temperature value, Tx / T. 设X itself.

[0051] The ambient temperature is currently higher than the set temperature, and the difference between the ambient and set temperatures is significant, indicating that this room requires substantial cooling. Therefore, an additional correction system is needed. Based on a ratio greater than 1, Tx / T... 设X It calculates the compressor frequency to achieve rapid cooling.

[0052] At this point, the value of the first coefficient has been determined based on the range of values ​​for the ratio of the detected temperature value to the preset temperature value.

[0053] See Figure 4 If the current operating mode is heating mode, proceed to step S11 after step S5 to determine Tx / T. 设X ≥1 means that the detected temperature value Tx of each powered-on room is compared with the preset temperature value T. 设xThe ratio is greater than or equal to the second preset ratio, which is 1.

[0054] If the result of step S11 is yes, then proceed to step S13, Tx / T 设X =0, Tx / T 设X As the first coefficient, the first coefficient takes a preset third value, which is 0 in this embodiment.

[0055] In this case, if the indoor ambient temperature is higher than or equal to the set temperature, it means that the room does not require additional heating.

[0056] If the result of step S11 is negative, then proceed to step S12 to determine whether 1 > Tx / T is satisfied. 设X ≥(T 设X -2) / T 设X That is, to determine the difference between the detected temperature value Tx of a certain room that is turned on and the preset temperature value T. 设X Is the ratio less than the second preset ratio 1 and greater than or equal to the second calculated value (T)? 设X -2) / T 设X The second calculated value (T) 设X -2) / T 设X Preset temperature value T 设X The difference between the fifth preset value and the preset temperature value T 设X The ratio of .

[0057] Second calculated value (T) 设X -2) / T 设X The setting is to determine whether the detected temperature value Tx is higher than the preset temperature value T. 设X The fifth preset value is lower than 2. For example, in this embodiment, the fifth preset value is 2. If the temperature value is set to 25, it is determined whether the current detection temperature value is 2 degrees lower than 25 degrees, that is, whether the detection temperature value is lower than 23 degrees.

[0058] If the result of step S12 is yes, then proceed to step S14, Tx / T 设X As the first coefficient, the first coefficient takes a preset fourth value, which is 1 in this embodiment.

[0059] At this time, the ambient temperature is lower than the set temperature, but the difference between the ambient temperature and the set temperature is small, indicating that the room does not require a large heating supply, and the compressor frequency can be calculated normally according to the preset area (actual area).

[0060] If the judgment result of step S12 is negative, then step S15 is executed. At this time, the detected temperature value Tx of the room is compared with the preset temperature value T. 设X The ratio is less than the second calculated value (T) 设X -2) / T 设XAt this point, the first coefficient is taken as the ratio of the detected temperature value to the preset temperature value, Tx / T. 设X itself.

[0061] The ambient temperature is currently lower than the set temperature, and the difference between the ambient and set temperatures is significant, indicating that the room requires substantial heating and necessitates the addition of a correction system. Therefore, based on a ratio greater than 1, Tx / T... 设X It calculates the compressor frequency to achieve rapid heating.

[0062] At this point, the value of the first coefficient has been determined based on the range of values ​​for the ratio of the detected temperature value to the preset temperature value.

[0063] like Figure 3 As shown, in steps S8, S9, and S10, and as... Figure 4 As shown, after determining the value of the first coefficient in steps S13, S14, and S15, step 16 is executed. See Figure 5 The second frequency P0 of the compressor is calculated according to formula 1.

[0064] Formula 1 is as follows:

[0065] In Formula 1, P max This represents the upper limit of the compressor's power; S 总 S1 represents the sum of the areas of all rooms connected to the area controller (total area of ​​all rooms), S2, ... represent the preset areas (pre-stored actual area data) corresponding to the rooms that are powered on. T1 represents the temperature detection value corresponding to the room powered on with S1, and T... 设1 This refers to the set temperature value corresponding to the room where the unit is turned on, and so on. Tx / T 设X It is the first coefficient calculated based on the above steps. The specific value of the first coefficient is the execution result of step S8, step S9, step S10, step S13, step S14 or step S15.

[0066] In Formula 1, S1×T1 / T 设1 The calculation result is used as the required area of ​​the operating room corresponding to S1 calculated according to the first coefficient and the preset area in this invention.

[0067] In Formula 1, (S1×T1 / T) 设1 + S2×T2 / T 设2 +…) / S 总 The calculation result serves as the second coefficient of this invention, calculated based on the sum of the required areas of each operating room and the total area of ​​all rooms.

[0068] In Formula 1, Pmax × (S1×T1 / T 设1 + S2×T2 / T 设2 +…) / S 总 The first frequency is generated by multiplying the second coefficient by a preset upper frequency limit.

[0069] The first preset value is to add an extra correction factor, and the recommended range for the first preset value is 2~10Hz. During the initial power-on phase, this extra correction factor is needed to achieve rapid cooling and heating.

[0070] The second frequency P0 is the sum of the first frequency and the first preset value.

[0071] In step S16, after calculating the second frequency P0 using formula 1, the second frequency P0 is not directly used as the target frequency.

[0072] Then, step S17 is executed to determine whether the calculated second frequency P0 is greater than the compressor's power upper limit value P. max .

[0073] If the judgment result of step S17 is yes, proceed to step S18, and the target frequency of the compressor is determined to be the upper limit of power P. max .

[0074] This situation indicates that there are a large number of rooms requiring air conditioning, resulting in a high demand for cooling / heating. However, to ensure the overall reliability of the unit, the compressor's target frequency cannot exceed its upper limit frequency value. Therefore, the upper limit power value P is chosen. max .

[0075] If the judgment result of step S17 is negative, proceed to step S19, and the target frequency of the compressor is determined to be the second frequency P0.

[0076] In this case, it means that the number of rooms that need to be air-conditioned is small, and the demand for air conditioning in terms of cooling and heating is small. The compressor frequency can be calculated normally according to the area. Therefore, the target frequency of the compressor is the second frequency P0 obtained from the actual result calculated by Formula 1.

[0077] The next step is to control the compressor operation according to the target frequency.

[0078] Then, step S20 is executed to determine if the compressor's cumulative running time is greater than or equal to the second preset value. The second preset value ranges from 5 to 30 minutes. After running for a period of time immediately after startup, the actual room temperature will drop rapidly in cooling mode and rise rapidly in heating mode. Therefore, the cumulative running time needs to be used to prepare for subsequent target frequency update calculations.

[0079] If the judgment result of step S20 is negative, then return to step S5 for real-time update; If the judgment result of step S20 is yes, then step S21 is executed: when the compressor's operating length is greater than or equal to the second preset value, the target frequency is updated. Here, the current second frequency P1 is recalculated according to the above formula 1.

[0080] Then, the judgment step S22 is executed to determine whether the difference (P0-P1) between the second frequency before and after the running time (second preset value) is greater than or equal to the third preset value (2~10Hz).

[0081] If the judgment result of step S22 is yes, then the first frequency P2 of the compressor is calculated according to formula 2, and the first frequency P2 is used as the updated target frequency.

[0082]

[0083] In fact, Formula 2, which is the part of Formula 1 that calculates the first frequency, does not add a first preset value for correction. In this case, it indicates that the room temperature drops rapidly, and the compressor's target frequency decreases rapidly. To achieve energy saving, the rapid cooling / heating mode can be exited, and there is no need to add a correction coefficient of the first preset value when calculating the compressor frequency.

[0084] Conversely, if the judgment result of step S22 is negative, the target frequency of the compressor decreases slowly and still needs to maintain the rapid cooling / heating mode. Therefore, step S24 is executed, and the second frequency P1 calculated by formula 1 at this time is used as the updated target frequency.

[0085] The main reason why the background technology failed to meet the actual cooling / heating needs of each room is that it did not take into account the different room sizes and different demand when calculating the target power of the compressor, and it did not take into account the impact of rooms that were not turned on on on the actual total demand.

[0086] In the control method of this invention, the second coefficient is calculated based on the relationship between the area of ​​each operating room and the total area of ​​all rooms. Specifically, when determining the area of ​​each room, the relationship between the detected temperature value of each operating room and the preset temperature value is considered to generate a required area value that meets actual needs. The second coefficient is then calculated by combining the sum of the required areas of each room with the total area of ​​all rooms. Finally, the target frequency is calculated by combining the second coefficient with the compressor's upper frequency limit. This method not only considers the relationship between the area of ​​each operating room and the demand, but also the difference between the current detected temperature and the set temperature, which also affects the demand. Therefore, the set area is corrected to ensure that the required area, the second coefficient, and the finally calculated compressor target frequency meet the cooling / heating needs of each operating room.
