Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a control method, a control device and an air conditioner of an air conditioning system. Background Art

[0002] When the air conditioner is in high temperature condition, in order to ensure rapid cooling, the air conditioner compressor runs for a long time at a high frequency to reach the set temperature as soon as possible. After the indoor temperature reaches the set temperature, it starts to reduce the frequency to maintain the indoor set temperature.

There is a certain deviation between the two. After the indoor temperature reaches the set temperature, as time goes by, the cold air continues to sink, which will cause the indoor temperature to be too cold, resulting in temperature over-adjustment, increased power consumption and failure to meet comfort requirements.

[0039] When the air conditioner is in high temperature condition, in order to ensure rapid cooling, the air conditioner compressor runs for a long time at a high frequency to reach the set temperature as soon as possible. After the indoor temperature reaches the set temperature, it starts to reduce the frequency to maintain the indoor set temperature. Because the room temperature change is a nonlinear process, the room temperature change is not strongly related to the current indoor temperature and does not consider the time dimension. There is a certain deviation between the two. After the indoor temperature reaches the set temperature, as time goes by, the cold air continues to sink, which will cause the indoor temperature to be too cold, resulting in temperature over-adjustment, increased power consumption and failure to meet comfort requirements.

The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0042] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the control device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0043] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication device, a user interface device, and a control program of the air conditioning system.

[0044] exist Figure 1 In the control device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the control device of the present invention can be set in the control device, and the control device calls the control program of the air-conditioning system stored in the memory 1005 through the processor 1001, and executes the control method of the air-conditioning system provided by the embodiment of the present invention.

[0045] The embodiment of the present invention provides a control method of an air conditioning system, referring to Figure 2 , Figure 2 The figure is a flow chart of an embodiment of a control method of an air conditioning system according to the present invention.

[0046] The control method of the air conditioning system comprises the following steps:

[0047] Step S10: After receiving the cooling mode instruction, obtain the current outdoor temperature.

[0048] In this embodiment, in order to obtain the outdoor temperature, the outdoor temperature data can be obtained through an outdoor temperature sensor, which is usually installed on the upper part of the air conditioner outdoor unit and can monitor the outdoor temperature in real time. When the user turns on the air conditioner and inputs a cooling mode command through a remote control or a control panel to control the air conditioner to start cooling, the air conditioning system can obtain the current outdoor temperature through the temperature sensor.

[0049] Step S20: when the current outdoor temperature is greater than or equal to the set threshold temperature, obtain the actual target temperature according to the real-time temperature and the set temperature, and control the air conditioning system to achieve the actual target temperature, wherein the actual target temperature is higher than the set temperature.

[0050] It should be noted that when the air conditioner is working, if the set temperature is low and the outdoor temperature is high, in order to reach the set temperature as quickly as possible, the air conditioning system is in a high-frequency working state. It should be noted that the high-frequency operation of the air conditioner means that the operating frequency of the compressor of the air conditioner is high during operation. The compressor of the air conditioner needs to compress the refrigerant into a high-temperature and high-pressure gas, so it needs to operate at a high frequency. The higher the operating frequency of the compressor, the better the cooling effect.

[0051] It should also be noted that the real-time temperature is the detected indoor temperature and outdoor temperature. In order to obtain the indoor temperature, the indoor temperature can be obtained through the indoor temperature sensor. During the operation of the air-conditioning system, the temperature sensor detects in real time and continuously updates the real-time temperature value.

[0052] In this embodiment, when the temperature sensor detects that the outdoor temperature reaches or exceeds the set threshold temperature, the current outdoor temperature is determined to be high temperature, and the air conditioning system is in a high temperature condition. Due to differences in individual physiques, the standards for determining high temperature vary. Preferably, when the set threshold temperature is set to 40°C, it meets the high temperature perception of most people. In order to achieve the purpose of cooling as quickly as possible, the user generally sets the set temperature to a temperature that the human body feels comfortable, or even lower than the comfortable temperature, so that the air conditioning system can work at a high frequency.

[0053] In the technical solution provided by the present invention, after receiving the cooling mode instruction, the user sets the set temperature and the air-conditioning system starts working. When it is detected that the current outdoor temperature reaches above the set threshold temperature, the air-conditioning system is in a high temperature working condition. The air-conditioning system uses a temperature value higher than the set temperature as the actual target temperature, and controls the air-conditioning system to work to achieve the actual target temperature. Because the actual target temperature is higher than the set temperature, and the air-conditioning system adjusts the working frequency according to the high and low matching of the target temperature, the indoor temperature gradually approaches the actual target temperature. As time goes by, the cold air sinks, and finally the indoor temperature is slightly lower than the actual target temperature, thereby being closer to the set temperature and meeting the comfort requirements, so as to solve the problem that the existing air-conditioning system is prone to overcooling under high temperature conditions.

[0054] In this embodiment, step S20: when the current outdoor temperature is greater than or equal to the set threshold temperature, the step of obtaining the actual target temperature according to the real-time temperature and the set temperature includes:

[0055] Step S21, obtaining the real-time temperature, and determining the actual target temperature according to the real-time temperature difference between the real-time temperature and the set temperature.

[0056] In this embodiment, as the air-conditioning system works, the real-time temperature in the room continues to decrease, and the real-time temperature difference between the real-time temperature and the set temperature will gradually decrease. Therefore, the cooling capacity required by the air-conditioning system is not constant, and the cooling demand will gradually decrease. Because the air-conditioning system adjusts the working frequency according to the target temperature, the working frequency of the air-conditioning compressor will gradually decrease automatically as time goes by. Therefore, in order to enable the compressor working frequency of the air-conditioning system to be matched and adjusted according to the real-time temperature, the actual target temperature can be determined according to the real-time temperature difference between the real-time temperature and the set temperature. When the difference is larger, it means that it is far from the target temperature and the required cooling capacity is larger. At this time, the air-conditioning system needs to work at a high frequency, so the actual target temperature also needs to be lower and closer to the set temperature to achieve the purpose of high-frequency operation of the compressor of the air-conditioning system; when the difference is smaller, it means that it is closer to the target temperature and the required cooling capacity is smaller. At this time, the air-conditioning system needs to work at a lower frequency, so the actual target temperature also needs to be higher to achieve the purpose of low-frequency operation of the compressor of the air-conditioning system. Therefore, the actual target temperature is dynamically adjusted according to the real-time temperature difference between the real-time temperature and the set temperature, so that the air conditioner can work at a preset frequency to achieve energy-saving effects and avoid increased power consumption.

[0057] In this embodiment, step S21: determining the actual target temperature according to the real-time temperature difference between the real-time temperature and the set temperature comprises:

[0058] Step S211, obtaining a real-time compensation coefficient according to the size of the real-time temperature difference.

[0059] In this embodiment, since the size of the real-time temperature difference is related to the operating frequency of the air-conditioning system, the larger the real-time temperature difference is, the lower the actual target temperature is; and the smaller the real-time temperature difference is, the higher the actual target temperature is. Therefore, the actual target temperature needs to be established by a real-time compensation coefficient.

[0060] Step S212: determining the actual target temperature according to the real-time compensation coefficient.

[0061] In one embodiment, the compensation coefficient can be a specific compensation temperature value, that is, the actual target temperature can be equal to the set temperature plus the compensation temperature. For example, when the set temperature is 26°C, the compensation temperature can be 1°C, then the actual target temperature is 26°C+1°C=27°C.

[0062] In another embodiment, the compensation coefficient may be a constant, that is, the actual target temperature may be the set temperature multiplied by the compensation coefficient. For example, when the set temperature is 25°C, the compensation coefficient is 1.04, then the actual target temperature is 25°C×1.04=26°C.

[0063] In this embodiment, step S211: the step of obtaining the real-time compensation coefficient according to the real-time temperature difference value includes:

[0064] Step S2111: If the real-time temperature difference is less than or equal to the first preset range value or the operation time of the air-conditioning system is greater than or equal to the set time, then determine the fixed compensation coefficient as the real-time compensation coefficient.

[0065] It is understandable that under high temperature conditions, when the temperature difference is large, the air-conditioning system needs to work at a high frequency, and the necessity of real-time dynamic compensation of the temperature coefficient is not great. Therefore, in the early stage of the cooling mode, a fixed compensation coefficient can be set as the real-time compensation coefficient, and the air-conditioning system can cool quickly by working at a high frequency.

[0066] When the air conditioning system has been working for a long time reaching the set time, the indoor temperature drops to close to the set temperature. The air conditioning system only needs to maintain the current operating frequency and there is no need to frequently switch the compensation coefficient.

[0067] It should be noted that the time it takes for the air conditioner to reach the set temperature is directly related to factors such as the air conditioner's capacity, the size of the room, the room's insulation, the outdoor ambient temperature, the set temperature, and the condition of the air conditioner itself. Under ideal conditions, the initial startup time is longer, and the subsequent startup time is about 15-20 minutes to reach the set temperature. However, the specific time will vary depending on factors such as the room area, outdoor ambient temperature, and set temperature. In this embodiment, the set time is n, where 25min≤n≤35min, preferably, n=30min. Under normal circumstances, the indoor temperature of the air conditioning system will basically reach the set temperature after running for about 30 minutes, and it will only maintain the set temperature afterwards, so it is more reasonable to set it to 30min.

[0068] Step S2112: if the real-time temperature difference value is less than the second preset range value, the real-time compensation coefficient is obtained according to the mapping relationship between multiple temperature difference intervals and multiple compensation parameters.

[0069] It is understandable that as the air-conditioning system works, the temperature gradually decreases and gets closer and closer to the set temperature. When the real-time temperature difference is within the second preset range, it is necessary to determine the real-time compensation value based on the real-time temperature in order to achieve the purpose of precise control and segmented frequency modulation.

[0070] In this embodiment, the second preset range value is set to 0.5°C≤m≤1.5°C, preferably, m=1°C. That is, when the temperature difference range value changes within the range of 1°C, the method of obtaining the dynamic compensation coefficient in real time is adopted to control the operation of the air conditioning system.

[0071] In the technical solution provided by the present invention, during the entire cooling process, the determination of the compensation coefficient is related to the size of the real-time temperature difference value and the operating time of the air-conditioning system. When the temperature difference value is large and no real-time compensation temperature value is required, a fixed compensation coefficient can be set as the compensation value. After the air-conditioning system has worked for a long enough time and maintained the set temperature state, a fixed compensation coefficient can also be set as the compensation value. After the air-conditioning system has worked for a period of time, when the temperature difference value is within the second preset range value, it is necessary to fine-tune the compensation. At this time, dynamic compensation is adopted to obtain the real-time temperature difference value in real time, and determine the real-time compensation coefficient according to the temperature difference interval where the temperature difference value is located.

[0072] In this embodiment, in step S2112: the step of obtaining the real-time compensation coefficient according to the mapping relationship between the multiple temperature difference intervals and the multiple compensation parameters includes:

[0073] Step S21121, establishing a mapping relationship between multiple temperature difference intervals and multiple compensation parameters.

[0074] In this embodiment, since the real-time temperature difference between the real-time temperature and the set temperature is a dynamic value, the compensation coefficient will also be different when the actual target temperature is dynamically adjusted. In order to accurately and quickly determine the compensation coefficient, a library can be established, and the compensation coefficient can be determined through the mapping relationship between multiple temperature difference intervals and multiple compensation parameters.

[0075] For example, there is a set relationship between the real-time temperature difference △T between the real-time temperature T1 and the set temperature Tset and the compensation coefficient A. Table 1 below is a mapping relationship chart corresponding to different temperature difference intervals and compensation coefficient data.

[0076] Table 1

[0077] T1-Tset Ta≤△T<Tb Tb≤△T<Tc Tc≤△T<Td Compensation coefficient A1 A2 A3 ……

[0078] Step S21122, determine the temperature difference range corresponding to the real-time temperature difference.

[0079] In this embodiment, the real-time temperature difference changes in real time as the air-conditioning system operates. However, since the operating frequency of the compressor is only adjusted between a plurality of limited frequencies, excessively frequent adjustments of the real-time target temperature are not very meaningful. Therefore, it is only necessary to determine that when the real-time temperature difference is within a certain range, the compensation coefficient can effectively adjust the operating frequency of the air-conditioning system.

[0080] Step S21123, matching the corresponding compensation coefficient according to the temperature difference interval to determine the real-time compensation coefficient.

[0081] In one embodiment, if A1, A2, A3, . . . are specific temperature values, when the real-time temperature difference is between Ta and Tb, the actual target temperature T=Tset+A1.

[0082] For example, when the current temperature is 27°C and the set temperature is 26°C, the real-time temperature difference △T is 1°C, and the compensation temperature A1 can be 0.5°C. Then the actual target temperature is 26°C+0.5°C=26.5°C. After the air-conditioning system adjusts the corresponding frequency and works for a certain period of time, when the real-time temperature reaches 26.6°C, the real-time temperature difference △T is 0.6°C. At this time, the compensation temperature A2 is 0.3°C. Then the actual target temperature is 26°C+0.3°C=26.3°C. After the air-conditioning system adjusts the corresponding frequency and works for a certain period of time, when the real-time temperature reaches 26.4°C, the real-time temperature difference △T is 0.4°C. At this time, the compensation temperature A2 is 0.1°C. Then the actual target temperature is 26°C+0.1°C=26.1°C... In this way, the actual target temperature is gradually set to be close to the set temperature, and at the same time, the working frequency of the air conditioner is continuously reduced to achieve energy-saving effects.

[0083] It is understandable that in order to gradually set the actual target temperature close to the set temperature, the arrangement order of the multiple compensation coefficients decreases with the decreasing value of the temperature difference range. That is, the larger the value of the temperature difference range, the greater the temperature difference, the greater the compensation coefficient, and the smaller the temperature difference, the smaller the compensation coefficient.

[0084] In another embodiment, if A1, A2, A3, . . . are constant coefficients, when the real-time temperature difference is between Ta and Tb, the actual target temperature T = Tset × A1.

[0085] In another embodiment, if A1, A2, A3, etc. are specific temperature values, when the real-time temperature difference is between Ta and Tb, the actual target temperature T = T1-A1. Of course, the setting method of the compensation coefficient and how to compensate to form the actual target temperature are not limited to the above examples. Under the inspiration of the technical essence of the embodiments of this specification, technicians in the relevant field may make other changes, but as long as the functions and effects achieved are the same or similar to the embodiments of this specification, they should be covered within the protection scope of the embodiments of this specification.

[0086] In this embodiment, the control method of the air conditioning system further includes:

[0087] Step S30: when the current outdoor temperature is less than the set threshold temperature, determine the set temperature as the actual target temperature, and control the air conditioning system to achieve the actual target temperature.

[0088] In this embodiment, when the current outdoor temperature is lower than the set threshold temperature, it indicates that the working condition of the air-conditioning system can be classified as a normal working condition. When the air-conditioning receives a cooling command, the compressor itself is not in a full-load high-frequency working state. Then, when the air-conditioning system is working, the compressor works at a lower frequency, providing a certain amount of time for the cold air to sink. The detected indoor temperature is not much different from the indoor temperature actually felt by the user. Therefore, after the real-time indoor temperature reaches the set temperature, the air-conditioning system can maintain a lower frequency of operation.

[0089] It should be understood that the above is only an example and does not constitute any limitation on the technical solution of the present invention. In specific applications, technicians in this field can make settings as needed, and the present invention does not limit this.
