[0002] Air-conditioning systems are extremely common in improving modern enterprises and living environments, and are even indispensable for certain living environments or production processes. Although air conditioners are currently relatively popular, many consumers still think that air conditioners consume a large amount of electricity, and there is a certain gap between the environmental temperature and the comfortable temperature required by users.

[0003] In the related art, in order to achieve the stability of indoor temperature / humidity, the refrigeration system, electric heating, and humidifier all independently adjust according to △T (actual indoor temperature - set temperature) and △d (actual indoor moisture content - set moisture content), and finally reach a dynamic balance, so that the indoor temperature / humidity reaches within the allowable error range of the set value. After the indoor temperature reaches equilibrium, the entire constant temperature and humidity refrigeration system will no longer be adjusted, and it will continue to operate in this mode.

[0004] However, in the related art, since the refrigeration system, electric heating, and humidifier can all automatically adjust the output, it is possible that all three output at a high power, and only constant temperature and humidity can be achieved, without achieving the energy-saving effect, and the intelligence and practicality are relatively low, which urgently needs to be improved.

[0023] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, but should not be construed as limiting the present application.

[0024] The energy-saving control method, device, electronic device and storage medium of the air-conditioning system according to the embodiments of the present application will be described below with reference to the accompanying drawings. In the related art mentioned in the above background art, since the refrigeration system, electric heating and humidifier can all automatically adjust their outputs, it is possible that all three output at a high power, and only constant temperature and humidity can be achieved, and the energy-saving effect cannot be achieved, and the intelligence and practicability are relatively low. The present application provides an energy-saving control method for an air-conditioning system. In this method, when it is determined that the air-conditioning system meets certain energy-saving conditions, the compressor, humidifier and electric heating can be simultaneously unloaded, so as to achieve energy saving while meeting the effect of constant temperature and humidity, and improve the intelligence and practicability of the air-conditioning system. Thus, the problems in the related art are solved, that is, since the refrigeration system, electric heating and humidifier can all automatically adjust their outputs, it is possible that all three output at a high power, and only constant temperature and humidity can be achieved, and the energy-saving effect cannot be achieved, and the intelligence and practicability are relatively low, etc.

[0025] Specifically, Figure 1 It is a schematic flow chart of an energy-saving control method for an air-conditioning system provided by an embodiment of the present application.

[0026] As Figure 1 shown, the refrigeration system of the air-conditioning system has at least two compressors. Among them, the energy-saving control method of the air-conditioning system includes the following steps:

[0027] In step S101, when the air-conditioning system is in the constant temperature and humidity control mode and the difference between the actual temperature and the target temperature in the room is within a preset constant temperature range, it is judged whether the current difference between the actual humidity and the target humidity in the room is less than or equal to a preset threshold.

[0028] It can be understood that the constant temperature and humidity control mode in the embodiments of the present application can control the indoor temperature, humidity fluctuation and regional deviation within a certain accuracy range by the air conditioner.

[0029] For example, in the embodiments of the present application, the difference between the actual temperature and the set temperature in the room can be ΔT, the preset constant temperature range can be [-T1, T1], the actual humidity in the room can be Δd, and the preset threshold can be d1. In the embodiments of the present application, when the air conditioner is in the constant temperature and humidity control mode and the difference between the actual temperature ΔT in the room and the target temperature is within a certain constant temperature range [-T1, T1], the indoor moisture content control is entered, and it is judged whether the difference between the actual humidity Δd in the room and the target humidity is less than or equal to a certain threshold d1, so as to provide a basis for subsequent judgment on whether the air conditioning system meets the energy-saving conditions, thereby meeting the constant temperature and humidity requirements and achieving the energy-saving effect.

[0030] It should be noted that the preset constant temperature range and the preset threshold can be set by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0031] In step S102, if the current difference is less than or equal to the preset threshold, it is judged whether the air conditioning system meets the preset energy-saving conditions. Among them, if the preset energy-saving conditions are met, while controlling the refrigeration system of the air conditioning system to reduce the number of compressors by one, the humidifier and the electric heater of the air conditioning system are controlled to reduce the corresponding power at the same time.

[0032] It can be understood that the air conditioner in the embodiments of the present application includes but is not limited to being composed of a refrigeration system, an electric heater, a humidifier, etc. The function of the refrigeration system is to adjust the temperature and play a role in cooling and dehumidifying; the function of the electric heater is to adjust the temperature and play a role in heating up, offsetting part of the cooling capacity of the refrigeration system, avoiding the indoor temperature being too low due to the cooling effect of the refrigeration system, and then the refrigeration system reaches the set temperature and stops, and after the refrigeration system stops, the dehumidification effect is lost, resulting in the humidity not reaching the desired target; the function of the humidifier is to adjust the humidity and increase the moisture content in the air. The refrigeration system, the electric heater and the humidifier in the embodiments of the present application are adjusted according to ΔT (the difference between the actual indoor temperature and the set temperature) and Δd (the difference between the actual indoor moisture content and the set moisture content).

[0033] In the actual execution process, in the embodiments of the present application, when the difference between the actual temperature Δd in the current room and the target humidity is less than or equal to a certain threshold d1, it is judged whether the air conditioning system meets certain energy-saving conditions. In the embodiments of the present application, when the air conditioning system meets certain energy-saving conditions, the refrigeration system of the air conditioning system is controlled to reduce the number of compressors by one, and at the same time, the humidifier and the electric heater of the air conditioning system are controlled to reduce the corresponding power at the same time, so as to further achieve the effect of both energy saving and constant temperature and humidity, and improve the intelligence and practicality of the air conditioning system.

[0034] Optionally, in an embodiment of the present application, the preset energy-saving conditions include that the loading number of the compressor of the refrigeration system of the air-conditioning system is greater than a preset threshold and the corresponding continuous operation duration is greater than a first preset duration, the output power of the electric heating is greater than a first preset power and the corresponding continuous operation duration is greater than a second preset duration, and the output power of the humidifier is greater than a second preset power and the corresponding continuous operation duration is greater than a third preset duration.

[0035] It can be understood that the refrigeration compressor in the embodiment of the present application is the core part of the refrigeration system and plays a role in compressing and driving the refrigerant in the air-conditioning refrigerant circuit. The preset threshold of the loading number of the compressor in the embodiment of the present application can be set to 1, and the first preset duration can be set to t cm , where t cm is the time (s) since the last operation of the refrigeration system; the first preset power of the electric heating can be set to Em, where Em represents the electric heating power output ratio, 40% for a 2-system, and 25% for a 4-system and above. The second preset duration can be set to t cm ; the second preset power of the humidifier can be set to Dm, where Dm represents the humidifier power output ratio, 40% for a 2-system, and 25% for a 4-system and above. The third preset duration can be set to t cm .

[0036] For example, in the embodiment of the present application, when the operation duration with the loading number of the compressor greater than 1 is greater than t cm and the operation duration with the output power of the electric heating greater than Em is greater than t cm and the operation duration with the output power of the humidifier greater than Dm is greater than t cm , it indicates that the current air-conditioning system meets certain energy-saving conditions, and thus can be unloaded to meet the energy-saving requirements; for another example, in the embodiment of the present application, when it does not meet that the operation duration with the loading number of the compressor greater than 1 is greater than t cm and the operation duration with the output power of the electric heating greater than Em is greater than t cm and the operation duration with the output power of the humidifier greater than Dm is greater than t cm for one or more of them, it indicates that the current air-conditioning system does not meet certain energy-saving conditions, and the air-conditioning system can be controlled to maintain the current operating state.

[0037] In step S103, if the current difference is greater than the preset threshold, it is determined whether the humidifier is working. If the humidifier is working, one compressor number of the refrigeration system is loaded or the air-conditioning system is controlled to maintain the current state.

[0038] For example, the preset threshold in the embodiments of the present application can be set to d1. When the difference between the actual humidity △d and the target humidity in the current room is greater than a certain threshold d1, it is determined whether the humidifier is working. When the humidifier is not working, the refrigeration system is controlled to operate according to the program that the actual humidity △d is less than or equal to a certain threshold d1; when the humidifier is working, the refrigeration system can be controlled to load a certain number of compressors or the air conditioning system is controlled to maintain the current state, so as to meet the requirements of constant temperature and humidity.

[0039] Optionally, in an embodiment of the present application, selecting to control the refrigeration system to load a certain number of compressors or control the air conditioning system to maintain the current state according to the humidity change trend in the room includes: obtaining the humidity change trend value in the room; when the humidity change trend is less than the preset trend value, controlling the air conditioning system to maintain the current state; when the humidity change trend is greater than or equal to the preset trend value, controlling the refrigeration system to load a certain number of compressors.

[0040] It can be understood that the embodiments of the present application can obtain the humidity change trend value in the room, which is represented by M1. Among them, the value is the average moisture content in the latter 30s - the average moisture content in the former 30s; the preset change trend in the embodiments of the present application can be set to 0.

[0041] For example, the embodiments of the present application can obtain the humidity change trend value M1 in the room. When the humidity change trend in the room is less than a certain trend value, that is, M1 < 0, the air conditioning system is controlled to maintain the current operating state. When the humidity change trend is greater than or equal to a certain trend value, that is, M1 ≥ 0, the refrigeration system is controlled to load a certain number of compressors, so that not only can the refrigeration system meet the requirements of constant temperature and humidity, but also the energy-saving effect can be achieved.

[0042] It should be noted that the preset trend value can be set by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0043] Optionally, in an embodiment of the present application, it further includes: if the current difference is less than or equal to the preset threshold and does not meet the preset energy-saving condition, then control the air conditioning system to maintain the current state.

[0044] As a possible implementation manner, the embodiments of the present application can control the air conditioning system to maintain the current operating state when the difference between the actual temperature and the target temperature in the room is less than or equal to a certain threshold and does not meet a certain energy-saving condition, so as to improve the intelligence and practicality of the air conditioning system and ensure the constant temperature and humidity state of the air conditioner.

[0045] Next, it can be combined with Figure 2 As shown, the working principle of the energy-saving control method of the air conditioning system in the embodiments of the present application will be elaborated in detail with a specific embodiment.

[0046] Step S201: Constant temperature and humidity control.

[0047] Step S202: -T1 ≤ △T ≤ T1.

[0048] In the embodiment of the present application, after the temperature reaches the set temperature (-T1 ≤ △T ≤ T1), the moisture content control can be entered.

[0049] Step S203: △d ≤ d1.

[0050] Step S204: The compressor load number > 1 for a time > t cm and the electric heating output > Em for a time > t cm and the humidifier output > Dm for a time > t cm , if so, execute Step S205, if not, execute Step S206.

[0051] In the embodiment of the present application, when △d ≤ d1, it can be judged whether, first, the running time of the compressor load number > 1 is > t cm ; second, the running time of the output power of the electric heating being greater than Em is > t cm ; third, the running time of the output power of the humidifier being greater than Dm is > t cm , if so, execute Step S205, if not, execute Step S206.

[0052] Step S205: t cm Unload one system and accompany with unloading Em of the electric heating and unloading Dm of the humidifier.

[0053] In the embodiment of the present application, when it satisfies that the compressor load number > 1 for a time > t cm and the electric heating output > Em for a time > t cm and the humidifier output > Dm for a time > t cm , execute Step S205, and the unit unloads one refrigeration system and is accompanied by unloading Em of the electric heating and unloading Dm of the humidifier.

[0054] Step S206: Maintain.

[0055] In the embodiment of the present application, when one or more of the conditions that the compressor load number > 1 for a time > t cm and the electric heating output > Em for a time > t cm and the humidifier output > Dm for a time > t cm are not satisfied, execute Step S206, and the unit maintains the current operating state.

[0056] Step S207: △d > d1.

[0057] Step S208: Judge whether the output of the humidifier is 0. If so, execute Step S209. If not, execute Step S204.

[0058] In the embodiment of the present application, when △d > d1, it can be determined whether the output of the humidifier is 0. If so, step S209 is executed; if not, step S204 is executed.

[0059] Step S209: Determine whether M1 < 0 is satisfied. If so, step S206 is executed; if not, step S210 is executed.

[0060] In the embodiment of the present application, when the output of the humidifier is 0, it can be determined whether M1 < 0 is satisfied. If so, step S206 is executed and the unit maintains the current operating state; if not, step S210 is executed to load a system.

[0061] Step S210: Load a system. In the embodiment of the present application, when M1 is greater than or equal to 0, the unit loads a refrigeration system.

[0062] According to the energy-saving control method of the air-conditioning system proposed by the embodiment of the present application, when it is determined that the air-conditioning system meets certain energy-saving conditions, the compressor, humidifier, and electric heater can be simultaneously unloaded, achieving energy saving while meeting the effect of constant temperature and humidity, and improving the intelligence and practicality of the air-conditioning system. Thus, the problem in the related art is solved that since the refrigeration system, electric heater, and humidifier can all automatically adjust their outputs, it is possible that all three output at a high power, only achieving constant temperature and humidity and unable to achieve energy-saving effects, with low intelligence and practicality.

[0063] Next, a description is given with reference to the drawings of an energy-saving control device for an air-conditioning system according to an embodiment of the present application.

[0064] Figure 3 It is a schematic structural diagram of an energy-saving control device for an air-conditioning system according to an embodiment of the present application.

[0065] As Figure 3 shown, the refrigeration system of the air-conditioning system has at least two compressors. Among them, the energy-saving control device 10 of the air-conditioning system includes: a judgment module 100, a first control module 200, and a second control module 200.

[0066] Specifically, the judgment module 100 is configured to determine whether the current difference between the actual humidity and the target humidity in the room is less than or equal to a preset threshold when the air-conditioning system is in the constant temperature and humidity control mode and the difference between the actual temperature and the target temperature in the room is within a preset constant temperature range.

[0067] The first control module 200 is configured to determine whether the air-conditioning system meets a preset energy-saving condition when the current difference is less than or equal to a preset threshold. Among them, if the preset energy-saving condition is met, while controlling the refrigeration system of the air-conditioning system to reduce the number of compressors by one, the humidifier and the electric heater of the air-conditioning system are controlled to reduce the corresponding power at the same time.

[0068] The second control module 300 is configured to determine whether the humidifier is working when the current difference is greater than the preset threshold. Among them, if the humidifier is working, the refrigeration system is controlled to load one compressor number or the air-conditioning system is controlled to maintain the current state.

[0069] Optionally, in an embodiment of the present application, the energy-saving control device 10 of the air-conditioning system further includes: a third control module.

[0070] Among them, the third control module is configured to control the air-conditioning system to maintain the current state when the current difference is less than or equal to the preset threshold and the preset energy-saving condition is not met.

[0071] Optionally, in an embodiment of the present application, the second control module 300 includes: an acquisition unit, a first control unit, and a second control unit.

[0072] Among them, the acquisition unit is configured to acquire the humidity change trend value in the room.

[0073] The first control unit is configured to control the air-conditioning system to maintain the current state when the humidity change trend is less than the preset trend value.

[0074] The second control unit is configured to control the refrigeration system to load one compressor number when the humidity change trend is greater than or equal to the preset trend value.

[0075] Optionally, in an embodiment of the present application, the preset energy-saving condition includes that the loading number of the compressors of the refrigeration system of the air-conditioning system is greater than the preset threshold and the corresponding continuous operation duration is greater than the first preset duration, the output power of the electric heater is greater than the first preset power and the corresponding continuous operation duration is greater than the second preset duration, and the output power of the humidifier is greater than the second preset power and the corresponding continuous operation duration is greater than the third preset duration.

[0076] It should be noted that the foregoing explanation of the embodiments of the energy-saving control method of the air-conditioning system also applies to the energy-saving control device of the air-conditioning system in this embodiment, and will not be elaborated here.

[0077] The energy-saving control device of the air-conditioning system proposed according to the embodiments of the present application can, when it is determined that the air-conditioning system meets certain energy-saving conditions, control the compressor, humidifier and electric heating to unload simultaneously, achieving energy saving while meeting the effects of constant temperature and humidity, and improving the intelligence and practicality of the vehicle. Thus, the problem in the related art is solved, that is, since the refrigeration system, electric heating and humidifier can all automatically adjust the output, it is possible that all three output at a high power, and only constant temperature and humidity can be achieved, and the energy-saving effect cannot be achieved, and the intelligence and practicality are relatively low.

[0079] A memory 401, a processor 402, and a computer program stored on the memory 401 and executable on the processor 402.

[0080] When the processor 402 executes the program, it implements the energy-saving control method of the air-conditioning system provided in the above embodiments.

[0081] Furthermore, the electronic device further includes:

[0082] A communication interface 403 for communication between the memory 401 and the processor 402.

[0083] The memory 401 is used to store the computer program executable on the processor 402.

[0084] The memory 401 may include a high-speed RAM memory, and may also include a non-volatile memory, such as at least one disk memory.

[0085] If the memory 401, the processor 402, and the communication interface 403 are independently implemented, the communication interface 403, the memory 401, and the processor 402 can be interconnected through a bus and complete communication with each other. The bus may be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, or an Extended Industry Standard Architecture (EISA) bus, etc. The bus can be divided into an address bus, a data bus, a control bus, etc. For the sake of representation, Figure 4 only a thick line is shown in the figure, but it does not mean that there is only one bus or one type of bus.
