[0046] In order to solve the problem that the use of redundant air conditioning equipment to assist the air conditioning equipment in energy-saving mode may lead to increased energy consumption and fail to achieve the real energy-saving effect, an air conditioning system is designed and provided.

[0047] As shown in Figure 1 The air conditioning system 1 includes a plurality of air conditioning equipment in communication connection.

[0048] In one or more embodiments of the application, at least one air conditioning equipment can adjust the indoor environment temperature of the current use environment, and the air conditioning equipment can be an air conditioner 10 for adjusting the indoor environment temperature of the current use environment.

[0049] The air conditioner 10 performs a refrigeration cycle of the air conditioner 10 by using a compressor, a condenser, a throttling element, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0050] The low-temperature and low-pressure refrigerant enters the compressor, which compresses the refrigerant gas into a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0051] The throttling element (for example, an electronic expansion valve) expands the high-temperature and high-pressure state liquid phase refrigerant formed in the condenser into a low-pressure liquid phase refrigerant. The evaporator evaporates the refrigerant expanded in the electronic expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by exchanging heat with a material to be cooled using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner 10 can adjust the temperature of the indoor space.

[0052] The outdoor unit of the air conditioner 10 refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger, the indoor unit of the air conditioner 10 includes the indoor heat exchanger, and the electronic expansion valve can be provided in the indoor unit or the outdoor unit.

[0053] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner 10 functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner 10 functions as a cooler in a cooling mode.

[0054] In one or more embodiments of the present application, the air conditioning device can be a fresh air device. The fresh air device includes a filter and a fan for removing particulate matter and harmful gases in the air while introducing fresh air to maintain indoor air freshness.

[0055] In one or more embodiments of the present application, the fresh air device can be a separate device or can be integrated into the air conditioner 10 as a functional module of the air conditioner 10.

[0056] In one or more embodiments of the present application, the air conditioning device can be an air purifier 11.

[0057] The air purifier 11 is a device for improving indoor air quality by removing particulate matter, gaseous pollutants, and harmful substances in the air, as well as eliminating odors and killing bacteria, and the like, to make the air fresher and healthier.

[0058] The air purifier 11 can be provided with a filtration system for removing particulate matter from the air. The filtration system can be a HEPA (High Efficiency Particulate Air Filter), an activated carbon filter, etc.

[0059] The air purifier 11 can also be provided with an ultraviolet lamp for killing bacteria, viruses, and other microorganisms in the air.

[0060] The air purifier 11 can also be provided with an ion generator to charge particulate matter in the air, making it easier to be captured by the filter.

[0061] In one or more embodiments of the present application, the air conditioning device can be a total heat exchanger.

[0062] The total heat exchanger can transfer heat between the incoming air and the exhaust air, achieving energy recovery, thereby pre-adjusting the temperature of the fresh air entering the building, reducing the energy needed for heating or air conditioning, reducing energy consumption, and saving energy expenditure. The total heat exchanger can also adjust the humidity under appropriate circumstances, helping to maintain the comfort and quality of indoor air.

[0063] In one or more embodiments of the present application, the air conditioning device can be a dehumidifier.

[0064] In one or more embodiments of the present application, the air conditioning device can be a humidifier.

[0065] In one or more embodiments of the present application, the air conditioning device can be an air circulation fan.

[0066] The air circulation fan is used to promote air flow, helping to evenly distribute pollutants and temperature in the air.

[0067] Multiple air conditioning devices are connected into a network based on a wireless communication protocol or a wired communication protocol, achieving data exchange and control.

[0068] In one or more embodiments of the present application, multiple air conditioning devices are connected to a router or gateway 12, and the router or gateway 12 is connected to a server 13. The air conditioning devices access the server 13 through the router or gateway 12, achieving data transmission and control.

[0069] The connection method can be a local area network, a signal line (including an Ethernet cable, a coaxial cable, an optical fiber, a power line, a serial line), a wireless signal, LTE, 5G, etc.

[0070] In an air conditioning system, multiple air conditioning devices can be independently operated, which can be controlled by a gateway or manually controlled by a user. In order to optimize energy consumption, at least part of the air conditioning devices are integrated with an energy saving mode. However, the comfort of indoor environment is determined by multiple factors and dynamically changes, and different users have different habits and preferences, so it is easy to have some air conditioning devices running in energy saving mode, but other air conditioning devices running redundantly to compensate for the energy saving effect, resulting in higher overall energy consumption of the air conditioning system. In particular, the functions of some air conditioning devices are overlapping, for example, air purifiers and fresh air systems can both improve air quality; if it is a system, without a global optimization algorithm, it is easy to have a situation of "losing one to gain the other" by controlling according to the setting of one or more air conditioning devices, for example, if the air conditioner runs in energy saving mode, the indoor environment temperature rises slightly, or the user is in a position under sunlight, the human body feels uncomfortable. The user is easy to use the air circulation fan to compensate, at this time the air circulation fan is easy to have overrunning, resulting in increased energy consumption.

[0071] As shown in Figure 2 To optimize the global strategy, in one or more embodiments of the present application, a processing device 20 is provided.

[0072] From the hardware point of view, the processing device 20 includes a processor, a volatile memory, a non-volatile memory, a display device, an operation device, a communication interface, and a driving device, etc. and are connected to each other through a bus. The processor can be a special purpose processor, a central processing device (CPU), etc. The processor can access the storage unit to execute instructions or applications stored in the storage unit to realize related functions. The display device is a display device for displaying various information, the operation device is an operation device for receiving various operations, and the driving device is a hardware terminal interacting with the storage medium. In one or more embodiments of the present application, the storage medium includes a medium such as CD-ROM, floppy disk, optical magnetic disk, ROM, flash memory, etc. to record information in an optical, electrical or magnetic way.

[0073] In one or more embodiments of the present application, the processing device 20 is a system on a board based on MCU.

[0074] In one or more embodiments of the present application, the processing device 20 is a controller of the air conditioning device itself.

[0075] In one or more embodiments of the present application, the processing device 20 is an upper computer.

[0076] In one or more embodiments of the present application, the processing device 20 is a cloud platform.

[0077] In one or more embodiments of the present application, the processing device 20 is a smart mobile terminal, such as a mobile phone or the like.

[0078] As shown in FIG. 2, in one or more embodiments of the present application, the processing device 20 includes a fusion load calculation module 201 and a set temperature correction module 202. Figure 3

[0079] In one or more embodiments of the present application, the fusion load calculation module 201 is configured to calculate the fusion load of the current use environment, which is calculated based on the power, use factor and demand factor of the plurality of air conditioning devices.

[0080] The power of the air conditioning device is the rated power of the device.

[0081] In one or more embodiments of the present application, the use factor is the ratio of the use time of the air conditioning device in a set period to the length of the set period.

[0082] In one or more embodiments of the present application, the set period can be 24 hours. The use factor is the proportion of the actual running time of the air conditioning device in a day to the total time. The use factor reflects the frequency of use of the device. For example, if a certain air conditioning device has been running for 12 hours in 24 hours, the use factor is 0.5.

[0083] In one or more embodiments of the present application, the demand factor is the ratio of the actual power consumption of the air conditioning device in a set period to the rated power consumption.

[0084] The demand factor indicates the ratio between the actual power consumption and the rated power consumption of the air conditioning device during use.

[0085] In one or more embodiments of the present application, the set temperature correction module 202 is configured to dynamically adjust the set temperature of the current use environment according to the fusion load, so that the set temperature of the current use environment matches the fusion load.

[0086] Through fusion load calculation, the processing device 20 can comprehensively plan the power, use factor and demand factor of all air conditioning devices, so as to determine the optimal set temperature of the current use environment, so that the set temperature of the current use environment matches the fusion load. Since the set temperature of the current use environment is dynamically adjusted according to the load of the entire air conditioning system 1, it ensures that the air conditioning devices work cooperatively, and different air conditioning devices maintain the lowest energy consumption while optimizing comfort.

[0087] As shown in FIG. 2, in one or more embodiments of the present application, the set temperature correction module 202 includes a setting unit 202-1 and a dynamic adjustment unit 202-2. Figure 4 ​​

[0088] In one or more embodiments of the present application, the setting unit 202-1 is configured to set the boundary comfortable temperature that the critical load can maintain as the set temperature of the current use environment when the fusion load exceeds the critical load.

[0089] In one or more embodiments of the present application, the dynamic adjustment unit 202-2 is configured to calculate the dynamic set temperature according to the boundary comfortable temperature that the critical load can maintain, the critical load and the fusion load when the fusion load does not exceed the critical load, and set the dynamic set temperature as the set temperature of the current use environment.

[0090] In one or more embodiments of the present application, the critical load is obtained by testing under experimental conditions. When testing the critical load, a reference load condition can be selected, the load is gradually increased by simulation until the air conditioning device cannot maintain the set temperature in the reference load condition, and the load is gradually reduced until the air conditioning device cannot maintain the set temperature in the reference load condition, the corresponding load is recorded as the critical load, and the critical load is stored for calling at any time.

[0091] In one or more embodiments of the present application, the critical load can be continuously updated based on machine learning in actual application scenarios.

[0092] In one or more embodiments of the present application, the boundary comfortable temperature that the critical load can maintain is obtained by testing under experimental conditions. Under the critical load (the critical load can be realized by simulating the internal heat load at a set outdoor temperature), the set temperature of the air conditioning device is gradually increased or decreased until the air conditioning device cannot maintain, the corresponding set temperature is recorded as the boundary comfortable temperature that the critical load can maintain, and the boundary comfortable temperature that the critical load can maintain is stored for calling at any time.

[0093] In one or more embodiments of the present application, the boundary comfortable temperature that the critical load can maintain can be continuously updated based on machine learning in actual application scenarios.

[0094] In one or more embodiments of the present application, the setting is configured to perform the following steps when the fusion load exceeds the critical load, and set the boundary comfortable temperature that the critical load can maintain as the set temperature of the current use environment.

[0095] When the fusion load is lower than the lower threshold of the critical load, the upper limit boundary comfortable temperature that the critical load can maintain is set as the set temperature of the current use environment.

[0096] For example, in the cooling mode, a plurality of steps as shown in Figure 5 are performed:

[0097] Step S101: judging whether the fusion load is lower than the lower threshold of the critical load.

[0098] Step S102: if the fusion load is lower than the lower threshold of the critical load, taking the highest temperature that the critical load can maintain as the set temperature of the current use environment.

[0099] In the heating mode, if the fusion load is lower than the lower threshold of the critical load, the upper limit boundary comfort temperature that the critical load can maintain is the lowest temperature.

[0100] When the fusion load is higher than the upper threshold of the critical load, taking the lower limit boundary comfort temperature that the critical load can maintain as the set temperature of the current use environment.

[0101] For example, in the cooling mode, a plurality of steps as shown in Figure 6 are performed:

[0102] Step S201: judging whether the fusion load is higher than the upper threshold of the critical load.

[0103] Step S202: if the fusion load is higher than the upper threshold, taking the lowest temperature that the critical load can maintain as the set temperature of the current use environment.

[0104] In the heating mode, if the fusion load is higher than the upper threshold of the critical load, the lower limit boundary comfort temperature that the critical load can maintain is the highest temperature.

[0105] When the fusion load is lower than the lower threshold of the critical load, the energy consumption of the air conditioning system 1 is reduced, and when the fusion load is higher than the upper threshold of the critical load, the cooling (heating) load demand is ensured to be met.

[0106] As shown in Figure 7 in one or more embodiments of the present application, the dynamic adjustment unit 202-2 is configured to, when the fusion load does not exceed the critical load, perform the following steps: calculating a dynamic set temperature according to the boundary comfort temperature that the critical load can maintain, the critical load and the fusion load, and taking the dynamic set temperature as the set temperature of the current use environment.

[0107] Step S301: calculating a set temperature change rate caused by load change based on the difference between the upper limit boundary comfort temperature and the lower limit boundary comfort temperature that the critical load can maintain, and the difference between the upper threshold of the critical load and the lower threshold of the critical load.

[0108] Step S302: calculating an offset of the fusion load relative to the upper threshold of the critical load based on the difference between the fusion load and the upper threshold of the critical load.

[0109] Step S303: calculating the dynamic set temperature based on the product of the set temperature change rate and the offset and the lower limit boundary comfortable temperature that can be maintained under the current load condition.

[0110] In the above manner, during dynamic load change, the dynamic set temperature provides sufficient refrigerating capacity when the load is high and reduces energy consumption when the load is low. At the same time, the upper limit boundary comfortable temperature and the lower limit boundary comfortable temperature ensure that the dynamic set temperature changes as expected and does not fluctuate greatly due to load fluctuations. The dynamic set temperature always smoothly transitions within different load intervals, improving the stability of the air conditioning system.

[0111] In one or more embodiments of the present application, the fusion load is the sum of the products of the power, the use factor and the demand factor of multiple air conditioning devices.

[0112] In one or more embodiments of the present application:

[0113] The upper limit threshold of the critical load is represented as Q max ;

[0114] The lower limit threshold of the critical load is represented as Q min ;

[0115] The fusion load is represented as Q f ;

[0116] The upper limit boundary comfortable temperature that can be maintained by the critical load is represented as T ev，out，max ;

[0117] The lower limit boundary comfortable temperature that can be maintained by the critical load is represented as T ev，out，min ;

[0118] The set temperature of the current use environment is represented as T ev，out .

[0119] Then:

[0120]

[0121] Q f =∑(ω×ν×λ)

[0122] Where ω is the power, v is the use factor, and λ is the demand factor.

[0123] is the estimated set temperature change rate caused by load change, Q f -Q max is the offset of the fusion load relative to the upper limit threshold of the critical load; is the dynamic set temperature.

[0124] In one or more embodiments of the present application, at least one air conditioning device can adjust the indoor air quality of the current use environment on the basis of the air conditioner 10. The air conditioning device that can adjust the indoor air quality of the current use environment can be an air purifier, an air conditioner with a fresh air module, a fresh air device, etc.

[0125] In one or more embodiments of the present application, the air conditioning device is in communication connection with the sensor module 30.

[0126] The sensor module 30 can detect the concentration of pollutants such as PM2.5, PM10, O3, CO, SO2 and NO2 in real time to calculate the air quality index (AQI).

[0127] In one or more embodiments of the present application, the processing device 20 further comprises a start confirmation module 203 configured to determine the start-stop of the plurality of air conditioning devices by using an optimization algorithm, with the goal that the total energy consumption of the air conditioning system 1 meets the preset energy consumption condition and the air quality index meets the preset air quality condition.

[0128] In one or more embodiments of the present application, the optimization algorithm is configured in the start confirmation module 203, wherein x i represents the start-stop state of each air conditioning device. For example, when x i = 1, it represents that the i-th air conditioning device is in a running state, and when x i = 0, it represents that the air conditioning device is in a closed state.

[0129] Taking the minimization of energy consumption as the objective function of the optimization algorithm, the objective function can be expressed as:

[0130]

[0131] where P i represents the power consumption of the i-th air conditioning device.

[0132] The constraint conditions of the objective function include one or more of the following:
