Description

Technical Field

[0001] This invention relates to the field of air conditioning control technology, and in particular to a control method and air conditioning system for a multi-split air conditioning system. Background Technology

[0002] Currently, for large-area applications requiring constant temperature and humidity, such as supermarkets and hospitals, most common air conditioning systems are multi-split air conditioning systems. In this system architecture, one outdoor unit connects to multiple indoor units, forming a centralized control mode. However, due to the limitations of this centralized control method, the outdoor unit can only uniformly control the operation of multiple indoor units, and cannot differentiate the needs of each indoor unit at the same time.

[0003] When multiple indoor units operate in different modes, meaning the air conditioning system simultaneously faces both cooling and heating demands, the outdoor units cannot differentiate and meet the cooling and heating needs of all indoor units in all areas. For example, if the indoor units in one area require cooling output while those in another area require heating output, under this centralized control mode, all indoor units can only operate in either cooling or heating mode. This means that the indoor units in some areas may fail to provide adequate air conditioning, or even produce the opposite temperature regulation effect, severely impacting user comfort and experience.

[0004] This situation is prevalent in current multi-split air conditioning systems, limiting their adaptability and flexibility in various complex environments. Therefore, improving and optimizing these systems is crucial for enhancing their performance and user experience. Summary of the Invention

[0005] The purpose of this invention is to provide a control method for a multi-split air conditioning system that can provide differentiated control so that indoor units located in different areas and with different needs can operate in different states.

[0006] To achieve the above objectives, this invention discloses a control method for a multi-split air conditioning system. The air conditioning system includes an outdoor unit and at least two indoor units connected to the outdoor unit, each located in a different usage area. Each indoor unit is configured with at least three operating modes: cooling mode, heating mode, and fan-operated mode. In cooling and heating modes, the indoor units exchange heat via refrigerant. In fan-operated mode, the indoor units output natural air. Each indoor unit is also equipped with an auxiliary electric heater. The control method includes:

[0007] Obtain the operating mode of each of the pre-required internal machine outputs to obtain the basic dataset;

[0008] When the proportion of cooling mode in the basic data is greater than zero, the outdoor unit is controlled to work in the cooling cycle state, and the indoor unit that requires pre-output as heating mode and air supply mode is controlled to be in air supply mode, and the auxiliary electric heater in the indoor unit that requires pre-output as heating mode is put into the on-demand turn-on state.

[0009] When the proportion of cooling mode in the basic data is zero and the proportion of heating mode is greater than zero, the outdoor unit is controlled to work in heating cycle state. At the same time, the indoor unit, which is pre-outputted as air supply mode, is controlled to be in air supply mode.

[0010] Preferably, the cooling mode includes a pure cooling mode and a first mixed cooling mode; in the first mixed cooling mode, the indoor unit dehumidifies based on heat exchange with the refrigerant, and simultaneously controls the auxiliary electric heater to be turned on as needed; when statistically analyzing the basic data, the sum of the proportions of the pure cooling mode and the first mixed cooling mode is taken as the proportion of the cooling mode; when the outdoor unit is working in the cooling cycle state, for the indoor unit that is required to output the first mixed cooling mode, the auxiliary electric heater in the indoor unit is controlled to be turned on as needed.

[0011] Preferably, the indoor unit is also equipped with an auxiliary electric humidifier, and the cooling mode includes a pure cooling mode and a second mixed cooling mode; in the second mixed cooling mode, the indoor unit performs heat exchange based on the refrigerant while controlling the auxiliary electric humidifier to be turned on as needed; when statistically analyzing the basic data, the sum of the proportions of the pure cooling mode and the second mixed cooling mode is taken as the proportion of the cooling mode.

[0012] Preferably, the heating mode includes a strong heating mode and a general heating mode; in the strong heating mode, the indoor unit performs heat exchange based on the refrigerant while simultaneously controlling the auxiliary electric heater to be turned on as needed; the indoor unit is also equipped with an auxiliary electric humidifier, and in the general heating mode, the indoor unit performs heat exchange based on the refrigerant while simultaneously controlling the auxiliary electric humidifier to be turned on as needed; when statistically analyzing the basic data, the sum of the proportions of the strong heating mode and the general heating mode is taken as the proportion of the heating mode.

[0013] Preferably, the indoor unit is also equipped with an auxiliary electric humidifier, and the working mode configured for the indoor unit also includes a humidification mode. When all the indoor units require the pre-output to be in humidification mode, while controlling the indoor unit to be in the air supply mode, the auxiliary heater in the indoor unit is also controlled to be turned on as needed.

[0014] Preferably, when the number of indoor units in any area of ​​use is greater than 1, the output mode of the indoor units in that area is uniformly selected according to the following conditions one and / or conditions two.

[0015] Condition 1: Within the usage area, the ratio of each of the operating modes pre-required by all the indoor units to all operating modes pre-required by all the indoor units within the usage area;

[0016] Condition 2: Within the area of ​​use, the energy requirement value of each of the operating modes that all the indoor units are required to output.

[0017] Preferably, the outdoor unit uses a variable frequency compressor. When the outdoor unit is in cooling cycle mode, the compressor adjusts its frequency according to the temperature difference between the preset evaporation temperature and the actual evaporation temperature, and simultaneously corrects the preset evaporation temperature according to the energy requirements of all indoor units. When the outdoor unit is in heating cycle mode, the compressor adjusts its frequency according to the temperature difference between the preset condensation temperature and the actual condensation temperature, and simultaneously corrects the preset condensation temperature according to the energy requirements of all indoor units.

[0024] Compared with the prior art, the control method disclosed in the above technical solution of the present invention has the following beneficial technical effects:

[0025] 1. Compared with the traditional centralized control method, the present invention allows indoor units in different areas to work in any of the three states of cooling, heating and ventilation at the same time, which effectively improves the flexibility of air conditioning zone control, and avoids wasting energy when cooling or heating is not needed, thereby improving the energy utilization efficiency of the air conditioning system.

[0026] 2. Since different usage areas can choose cooling, heating or natural air supply according to actual needs, more personalized air conditioning services can be provided, improving the user experience. Attached Figure Description

[0029] Figure 3 This is a flowchart illustrating the specific execution of the control method in one embodiment of the present invention.

[0030] Figure 4 This is a flowchart illustrating the specific execution of the control method in another embodiment of the present invention. Detailed Implementation

[0031] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0032] This embodiment discloses a control method for a multi-split air conditioning system, enabling flexible control of the system's operation and providing differentiated services to indoor units in different areas. Specifically, as shown... Figure 1 The air conditioning system in this embodiment includes one outdoor unit and at least two indoor units located in different usage areas. Each indoor unit is equipped with at least three operating modes: cooling mode, heating mode, and ventilation mode. In cooling and heating modes, the indoor unit exchanges heat through refrigerant, meaning the refrigerant in the outdoor unit is in a circulating state to regulate the air temperature of the area. In ventilation mode, the indoor unit outputs natural airflow to increase air circulation in the area. That is, in ventilation mode, the outdoor unit is in a stopped or standby state, the refrigerant is in a non-flowing state, and the heat exchanger in the indoor unit cannot perform heat exchange between the refrigerant and the indoor air. In addition, each indoor unit is also equipped with an auxiliary electric heater M1 to assist the indoor unit in independently heating the ambient air.

[0033] Air conditioning systems based on the above structure, such as Figure 2 The control method in this embodiment includes the following steps:

[0034] S1: First, obtain the working mode required by each indoor unit in advance. This information will constitute a basic dataset.

[0035] Next, the operating status of the outdoor unit is controlled based on the analysis of the basic dataset. Specifically, since the indoor unit is equipped with an auxiliary electric heater M1, the cooling needs of the indoor unit can be prioritized.

[0036] S2: Determine whether the proportion of cooling mode in the basic dataset is greater than zero. If yes, proceed to step S3; otherwise, proceed to step S4.

[0037] S3: Indicates that at least one indoor unit requires cooling mode, in which case the outdoor unit will be controlled to operate in cooling cycle mode. This way, the indoor unit requesting cooling mode will operate as requested. Simultaneously, indoor units requesting heating and fan-only modes will be controlled to fan-only mode, and the auxiliary heater in the indoor unit requesting heating mode will be on-demand. This satisfies the diverse cooling, heating, and fan-only needs of any area in the current environment.

[0038] S4: If the proportion of cooling mode in the basic dataset is zero, that is, no indoor unit requires output in cooling mode, determine whether the proportion of heating mode is greater than zero. If yes, proceed to S40; otherwise, proceed to S41.

[0039] S40: Controls the outdoor unit to operate in heating cycle mode. This ensures that indoor units requiring heating output will operate accordingly. Simultaneously, it controls indoor units requiring fan-operated output to operate in fan-operated mode. This satisfies the diverse heating and fan-operated needs of any area in the current environment.

[0040] S41: Controls the outdoor unit to be in a stopped or standby state.

[0041] In summary, this control method, by flexibly adjusting the status of the indoor and outdoor units, achieves maximum energy savings while meeting the diverse needs of different areas. Furthermore, this method allows for more refined adjustments based on environmental and user requirements, thereby providing more comfortable and energy-efficient air conditioning services. This method has high application value for multi-split air conditioning systems in large public places such as shopping malls, hospitals, and schools.

[0042] On the other hand, the cooling modes include pure cooling mode and first mixed cooling mode. In the first mixed cooling mode, the indoor unit dehumidifies based on heat exchange with the refrigerant, while simultaneously controlling the auxiliary electric heater to operate on demand. When statistically analyzing the basic data, the sum of the proportions of pure cooling mode and first mixed cooling mode is taken as the proportion of cooling modes. When the outdoor unit is operating in the cooling cycle state, for indoor units that are required to output the first mixed cooling mode, the auxiliary electric heater in that indoor unit is controlled to operate on demand.

[0043] In this embodiment, the cooling mode is further subdivided into a pure cooling mode and a first mixed cooling mode. In pure cooling mode, the indoor unit cools the environment solely through heat exchange between the refrigerant and the air. In the first mixed cooling mode, the indoor unit dehumidifies the environment based on cooling, and also activates the auxiliary electric heater M1 as needed to ensure that the temperature of the environment is maintained at the required level, thereby providing users with a constant temperature and humidity indoor environment. Furthermore, when calculating basic data, both the pure cooling mode and the first mixed cooling mode are counted as cooling modes. For example, if one indoor unit requires output in pure cooling mode and another requires output in the first mixed cooling mode, then the statistical data for the current cooling mode is 2.

[0044] In some usage scenarios, the air is relatively dry, and users desire a humidification function from the air conditioner. Further improvements are needed in this regard, such as... Figure 2 An auxiliary electric humidifier M2 is installed in the indoor unit, so that the indoor unit can turn on the auxiliary electric humidifier M2 as needed to humidify the current indoor environment.

[0045] In response, the cooling mode also includes a second hybrid cooling mode. In the second hybrid cooling mode, the indoor unit performs heat exchange based on the refrigerant while simultaneously controlling the auxiliary electric humidifier M2 to operate on demand. When statistically analyzing the basic data, the sum of the proportions of the pure cooling mode, the first hybrid cooling mode, and the second hybrid cooling mode is taken as the proportion of the cooling mode.

[0046] When the indoor unit is in cooling mode, it has a dehumidification function. Therefore, if the current indoor humidity is too low, the indoor unit can be set to the second hybrid cooling mode. In this mode, the indoor unit exchanges heat with the surrounding air based on the refrigerant, and also humidifies the surrounding air based on the humidifier, thereby providing a comfortable environment for users.

[0047] On the other hand, the heating modes include a strong heating mode and a standard heating mode. In strong heating mode, the indoor unit exchanges heat using refrigerant while simultaneously controlling the auxiliary electric heater M1 to operate on demand. In standard heating mode, the indoor unit exchanges heat using refrigerant while simultaneously controlling the auxiliary electric humidifier M2 to operate on demand. When statistically analyzing the basic data, the sum of the proportions of strong heating mode and standard heating mode is taken as the proportion of heating modes; that is, both strong heating mode and standard heating mode are counted as heating modes.

[0048] In this embodiment, when the outdoor unit is in heating cycle mode, if the indoor unit is required to output strong heat mode, the auxiliary electric heater M1 on the indoor unit will be turned on as needed; if the indoor unit is required to output general heat mode, the auxiliary electric humidifier M2 on the indoor unit will be turned on at the same time, so as to provide humidification effect to the surrounding air while heating it.

[0049] On the other hand, in some situations, the indoor ambient temperature is within a suitable range, but the air is relatively dry, requiring only humidification from the air conditioner. For this, the indoor unit is configured with a humidification mode. When all indoor units are required to output humidification mode, the indoor units are controlled to be in fan mode, the outdoor units are in off or standby mode, and the auxiliary heater in the indoor units is also controlled to be turned on as needed, so that the indoor units output natural air while also providing humidification to the surrounding air.

[0050] In summary, the control method disclosed in this invention configures each indoor unit with six operating modes: pure cooling mode, first mixed cooling mode, second mixed cooling mode, strong heating mode, general heating mode, humidification mode, and air supply mode. During the operation of the air conditioning system, the operating mode of each indoor unit's pre-required output is statistically analyzed in real time.

[0051] like Figure 3 When at least one indoor unit requests to pre-output a cooling mode (pure cooling mode, first mixed cooling mode, or second mixed cooling mode), the outdoor unit is controlled to be in cooling cycle mode, and the actual operating mode of the indoor unit is determined according to the following requirements:

[0052] If the indoor unit requires the pre-output operating mode to be any one of pure cooling mode, first mixed cooling mode, or second mixed cooling mode, then control the indoor unit to operate in the corresponding required operating mode.

[0053] If the indoor unit requires a strong heating mode or a normal heating mode, then control the indoor unit to be in the air supply mode, and simultaneously turn on the auxiliary electric heater M1 as needed;

[0054] If the indoor unit requires humidification mode, control the indoor unit to be in air supply mode, and at the same time turn on the auxiliary electric humidifier M2 as needed to adjust the humidity;

[0055] If the indoor unit only requires the air supply mode, then control the indoor unit to be in the air supply mode.

[0056] like Figure 4 When no indoor unit requests cooling mode (pure cooling mode, first mixed cooling mode, or second mixed cooling mode), and at least one indoor unit requests heating mode (strong heating mode or general heating mode), the outdoor unit is controlled to be in heating cycle mode, and the actual operating mode of the indoor unit is determined according to the following requirements:

[0057] If the indoor unit requires a strong heating mode or a normal heating mode, then control the indoor unit's operating status according to the demand.

[0058] If the indoor unit requires the air supply mode, then control the indoor unit to be in the air supply mode;

[0059] If the indoor unit requires humidification mode, then control the indoor unit to be in air supply mode while also turning on the electric humidifier.

[0060] On the other hand, in some applications, multiple indoor units will be installed in the same area of ​​use. Since the environmental requirements of the same area of ​​use are generally the same, in order to make different indoor units in the same area work in the same working mode, when the number of indoor units in any area of ​​use is greater than 1, the output mode of the indoor units in that area will be uniformly executed according to the following conditions one and / or conditions two.

[0061] Condition 1: Within the usage area, the ratio of each operating mode of all indoor units pre-required output to all operating modes of all indoor units pre-required output within the usage area;

[0062] Condition 2: Within this usage area, the energy requirement value of each operating mode of all indoor units is pre-requisite.

[0063] Specifically, for a certain area A, there are three indoor units installed. If one indoor unit requires cooling mode output and the other two indoor units require heating mode output, then according to condition one, since the proportion of heating mode output in area A is 2 / 3 and the proportion of cooling mode output is 1 / 3, the three indoor units in area A are controlled to uniformly output heating mode.

[0064] In another scenario, for a certain area B, there are four indoor units installed. If two indoor units P1 and P2 require cooling mode output, and the other two indoor units P3 and P4 require heating mode output, then since it cannot be determined according to condition one, it can be determined according to condition two. Specifically, obtain the sum of the energy requirements of indoor units P1 and P2 (W1), and obtain the sum of the energy requirements of indoor units P3 and P4 (W2). Then compare the values ​​of W1 and W2. If W1 > W2, then control all four indoor units in area B to uniformly execute cooling mode; if W1 < W2, then control all four indoor units in area B to uniformly execute heating mode.

[0065] In the other extreme case, for a certain area C, if the proportion of cooling mode and heating mode outputs of all indoor units is the same, and the energy demand of the indoor units corresponding to these two modes is also the same, then all indoor units in area C can be randomly controlled to uniformly execute either cooling mode or heating mode.

[0066] To facilitate the differentiation of the usage area to which each indoor unit belongs, each indoor unit can be numbered according to the usage area, and all indoor units located in the same usage area can use the same area number.

[0067] On the other hand, the outdoor unit uses an inverter compressor. When the outdoor unit is in cooling cycle mode, the compressor adjusts its frequency based on the temperature difference between the preset evaporation temperature and the actual evaporation temperature, and simultaneously corrects the preset evaporation temperature based on the energy requirements of all indoor units. When the outdoor unit is in heating cycle mode, the compressor adjusts its frequency based on the temperature difference between the preset condensation temperature and the actual condensation temperature, and simultaneously corrects the preset condensation temperature based on the energy requirements of all indoor units.

[0068] In another preferred embodiment of the present invention, a multi-split air conditioning system is also disclosed, such as... Figure 1 It includes an outdoor unit, at least two indoor units located in different usage areas connected to the outdoor unit, and a control system that operates based on the control method described above.

[0070] The present invention also discloses a computer-readable storage medium comprising a computer program executable by a processor to perform the control method described above. The computer-readable storage medium can be any available medium accessible to a computer or a data storage device such as a server or data center integrating one or more available media.
