[0035] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which like or similar elements or components are denoted by like reference numerals, and the embodiments described below are examples for explaining the present application and are not to be construed as limiting the present application.
[0036] An air conditioning system and a control method thereof, and a storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.
[0037] Figure 1 is a structural schematic diagram of an air conditioning system according to an embodiment of the present application.
[0038] As shown in Figure 1 , the air conditioning system comprises a fresh air device 10, an air conditioning device 20 and a control device 50, the air conditioning device 20 comprises an indoor unit 22 and an outdoor unit 21, the outdoor unit 21 comprises a compressor 23, and the outdoor unit 21 is connected to the indoor unit 22 through refrigerant pipes 25, the indoor unit 22 is provided with a return air sensor 24, and the control device 50 is connected to the fresh air device 10 and the air conditioning device 20 respectively. In the figure, the indoor unit 22 is arranged in a sub-space 30, and the fresh air device 10 is also arranged outside the sub-space 30, and the fresh air device 10 and the sub-space 30 are arranged in a total space 40.
[0039] The control device 50 can acquire an indoor air parameter when it is determined that the air conditioning device 20 is in a preset state, and then control the fresh air device 10 according to the indoor air parameter to reduce the energy consumption of the air conditioning device 20, wherein the preset state can be an on state of the air conditioning device 20 or an off state of the air conditioning device 20, and the indoor air parameter can include the humidity content of the indoor environment and the temperature of the indoor return air. Specifically, when it is determined that the air conditioning device 20 is in the on state, the control device 50 can control the fresh air device 10 according to the humidity content of the indoor environment, and when it is determined that the air conditioning device 20 is in the off state, the control device 50 can control the fresh air device 10 according to the temperature of the indoor return air.
[0040] More specifically, referring to Figure 1 , the fresh air device 10 includes an exhaust air fan 13, a supply air fan 12 and an adsorption wheel 11, and further includes an indoor return air port, an outdoor fresh air port, an indoor supply air port and an outdoor exhaust air port. The outdoor fresh air OA can enter the fresh air device 10 from the outdoor fresh air port and enter the indoor environment, i.e. the sub-space 30, under the guidance of the supply air fan 12 and be supplied to the sub-space 30 as the indoor supply air SA. The indoor return air port of the fresh air device 10 is arranged in the sub-space 30, through which the indoor return air RA in the sub-space 30 can be introduced into the fresh air device 10, and the exhaust air fan 13 can exhaust the indoor return air RA as the outdoor exhaust air EA. The adsorption wheel 11 in the embodiment can be used for sensible heat and latent heat exchange according to the indoor return air and the outdoor fresh air, thereby humidifying and / or energy recovering the indoor environment.
[0041] Further, the fresh air device 10 is provided with corresponding temperature and humidity sensors near the indoor return air port, the outdoor fresh air port and the indoor supply air port. The indoor return air port is provided with a return air temperature and humidity sensor 15, the outdoor fresh air port is provided with a fresh air temperature and humidity sensor 17, and the indoor supply air port is provided with a supply air temperature and humidity sensor 16 to detect the temperature and humidity of the corresponding air.
[0042] Figure 2 is a control method flow diagram of an air conditioning system according to an embodiment of the application.
[0043] As shown in Figure 2 , the application provides a control method of an air conditioning system, which can be applied to the control device 50 in the air conditioning system described above. Figure 1
[0044] The control method in the embodiment includes the following steps:
[0045] S10, determining the moisture content of the indoor environment when the air conditioning device is in an open state.
[0046] Specifically, when the air conditioning device in the embodiment is in an open state, it needs to be controlled not to be frequently started and stopped, thereby enabling energy-saving control of the air conditioning device. The reason why the air conditioning device needs to be started and stopped is mainly that when the indoor temperature meets the target temperature during the refrigeration or heating process of the air conditioning device, the air conditioning device is controlled to stop, and after the air conditioning device stops, the indoor temperature changes and does not reach the target temperature again, and then the air conditioning device is started again. Once the control is repeated.
[0047] Further, since the comfort of the environment is related to the humidity content, when determining the target regulation temperature of the air conditioning device, the humidity content of the indoor environment can be determined first, and then the target regulation temperature meeting the comfort requirement of the user can be determined according to the humidity content.
[0048] S20, determining the target regulation temperature of the air conditioning device according to the humidity content of the indoor environment.
[0049] Specifically, after the humidity content of the indoor environment is determined, the target regulation temperature of the air conditioning device can be determined by looking up the table according to the humidity content of the indoor environment. It can be understood that the temperature range meeting the comfort requirement of the user can be determined according to the humidity content, and then the temperature with the minimum energy consumption in the temperature range is taken as the target regulation temperature. For example, when the air conditioning device is in cooling, the maximum temperature in the temperature range is taken as the target regulation temperature.
[0050] S30, controlling the air conditioning device according to the target regulation temperature, and obtaining the current regulation temperature of the air conditioning device.
[0051] Specifically, after the target regulation temperature is determined, the air conditioning device can be controlled according to the target regulation temperature, so that the temperature of the indoor environment can be controlled to be equal to the target regulation temperature, and the energy saving requirement can be achieved. However, it should be noted that during the control of the air conditioning device, it is possible that the air conditioning device can no longer continue to regulate the indoor environment according to the target regulation temperature, for example, the rotation speed of the compressor of the air conditioning device has reached the minimum rotation speed, and if the regulation continues, the air conditioning device may enter the shutdown state. That is, the air conditioning device has a certain regulation temperature range, so during the control of the air conditioning device according to the target regulation temperature, the current regulation temperature of the air conditioning device is also obtained.
[0052] S40, when it is determined that the current regulation temperature is in the first preset regulation range, the fresh air device is controlled to avoid frequent start and stop of the air conditioning device.
[0053] Specifically, if the current regulation temperature of the air conditioning device is in the first preset regulation range, it indicates that the air conditioning device will enter the shutdown state at this time, so in order to prevent the air conditioning device from shutting down, the fresh air device can be controlled in this embodiment, that is, the load of the air conditioning device is appropriately increased to avoid frequent start and stop of the air conditioning device.
[0054] In this embodiment, as shown in Figure 3 the control method further includes the following steps:
[0055] S301, obtaining the temperature of the indoor return air when the air conditioning device is in the off state.
[0056] Specifically, when the air conditioning device is in the off state, in order to control the air conditioning device to save energy, the fresh air device can be controlled to avoid the air conditioning device from being turned on. The air conditioning device can be controlled according to the temperature of the indoor environment, and when the air conditioning device is in the off state, the temperature of the indoor return air can be continuously obtained to determine whether the temperature of the current indoor environment needs to be adjusted.
[0057] S302, when it is determined that the temperature of the indoor return air is in the second preset adjustment range, the fresh air device is controlled to avoid the air conditioning device from being turned on.
[0058] Specifically, after obtaining the temperature of the indoor return air, the temperature of the indoor return air can be determined to determine whether it is in the second preset adjustment range. If it is determined that the temperature of the indoor return air is in the second preset adjustment range, it indicates that the temperature of the current indoor environment needs to be adjusted, but in order to avoid the opening of the air conditioning device for energy saving, the fresh air device is controlled in this embodiment.
[0059] In this embodiment, determining the moisture content of the indoor environment includes: obtaining the humidity of the indoor return air; and determining the moisture content of the indoor environment according to the temperature and humidity of the indoor return air.
[0060] It can be understood that the moisture content of the indoor environment has a certain corresponding relationship with the humidity of the indoor return air and the temperature of the indoor return air. Specifically, the moisture content of the indoor environment can be first determined according to experimental data to establish a moisture content query table of the indoor environment. The temperature and humidity of the indoor return air correspond to different moisture contents of the indoor environment, that is, after the humidity and temperature of the indoor return air are detected by the temperature and humidity sensor near the indoor return air outlet, the moisture content of the indoor environment can be directly determined by table lookup, and the corresponding target adjustment temperature is determined according to the moisture content.
[0061] In an embodiment of the present application, the target adjustment temperature includes a target evaporation temperature, that is, when the air conditioning device is in a refrigeration working condition, the current adjustment temperature includes a current evaporation temperature, and the air conditioning device is controlled according to the target adjustment temperature, including: reducing the speed of the indoor unit fan and the speed of the compressor according to the target evaporation temperature, so that the current evaporation temperature of the air conditioning device is equal to the target evaporation temperature.
[0062] Specifically, the target adjustment temperature in this embodiment is the target evaporation temperature, that is, the air conditioning device is in a refrigeration working condition. In the process of adjusting the air conditioning device to make the current adjustment temperature of the air conditioning device equal to the target adjustment temperature, the speed of the indoor unit fan and the speed of the compressor can be reduced, that is, the refrigeration capacity is reduced.
[0063] In this embodiment, when it is determined that the current adjustment temperature is in the first preset adjustment range, the fresh air device is controlled, including: when it is determined that the current evaporation temperature is greater than or equal to the preset evaporation temperature, if the temperature of the indoor return air is less than the temperature of the outdoor fresh air, the rotation speed of the driving motor is reduced, and / or the rotation speed of the exhaust air side fan is increased, and / or the rotation speed of the supply air side fan is increased; if the temperature of the indoor return air is greater than the temperature of the outdoor fresh air, the rotation speed of the exhaust air side fan and / or the rotation speed of the supply air side fan is reduced.
[0064] Specifically, when it is determined that the current evaporation temperature is greater than or equal to the preset evaporation temperature, it indicates that the air conditioning device will possibly enter a shutdown state, and then the fresh air device needs to be controlled to increase the load of the air conditioning device. Due to the difference between indoor and outdoor temperatures, different controls of the fresh air device are needed to increase the load of the air conditioning device.
[0065] More specifically, the embodiment compares the temperature between indoor and outdoor by detecting the temperature of the indoor return air and the temperature of the outdoor fresh air. In the case that the temperature of the indoor return air is less than the temperature of the outdoor fresh air, it indicates that the indoor temperature is less than the outdoor temperature, and this working condition is possibly in summer, when the air conditioning device is in refrigeration and the fresh air device is in full heat recovery to recover the cold energy of the indoor return air. Therefore, in order to increase the load of the air conditioning device, the rotation speed of the driving motor can be reduced, and / or the rotation speed of the exhaust air side fan can be increased, and / or the rotation speed of the supply air side fan can be increased. As shown in the figure, in this working condition, the energy-saving control of the air conditioning device includes the following steps: Figure 4
[0066] S401, acquiring the temperature and humidity of the indoor return air;
[0067] S402, determining the humidity content of the indoor environment;
[0068] S403, determining the target evaporation temperature;
[0069] S404, reducing the rotation speed of the indoor unit fan and the rotation speed of the compressor;
[0070] S405, acquiring the current evaporation temperature;
[0071] S406, whether the current evaporation temperature is greater than or equal to the preset evaporation temperature, if yes, executing step S407, otherwise, re-executing step S404;
[0072] S407, reducing the rotation speed of the driving motor, and / or increasing the rotation speed of the exhaust air side fan, and / or increasing the rotation speed of the supply air side fan.
[0073] When the indoor return air temperature is higher than the outdoor fresh air temperature, i.e., during the transitional season (spring and autumn), the air conditioning equipment operates on demand for cooling. Since the outdoor temperature is typically lower than the indoor temperature during this transitional season, the load on the air conditioning equipment can be increased by reducing the speed of the exhaust fan and / or the supply fan. Furthermore, in this embodiment, if the indoor return air temperature is determined to be within a second preset adjustment range, the fresh air equipment is controlled, including increasing the speed of the exhaust fan and / or the supply fan when the indoor return air temperature is higher than both the first preset temperature and the outdoor fresh air temperature.
[0074] Specifically, if the air conditioning equipment is off during the transition season and the indoor return air temperature is higher than the first preset temperature, the load can be reduced by increasing the speed of the exhaust side fan and / or the supply side fan to prevent the air conditioning equipment from turning on, thereby achieving energy-saving control of the air conditioning equipment. It should be noted that the first preset temperature in this embodiment can be a temperature set by the user or determined based on the parameters of the fresh air system.
[0075] like Figure 5 As shown, under this operating condition, energy-saving control of the air conditioning equipment includes the following steps:
[0076] S501, Determine whether the air conditioning unit is turned on. If it is turned on, proceed to step S502; otherwise, proceed to step S509.
[0077] S502, obtains the temperature and humidity of the indoor return air;
[0078] S503, determine the humidity level of the indoor environment;
[0079] S504, determine the target evaporation temperature;
[0080] S505 reduces the indoor unit fan speed and compressor speed;
[0081] S506, obtain the current evaporation temperature;
[0082] S507, Determine whether the current evaporation temperature is greater than or equal to the preset evaporation temperature. If yes, proceed to step S508; otherwise, repeat step S505.
[0083] S508, reduce the speed of the exhaust side fan and / or the supply side fan;
[0084] S509, obtain the indoor return air temperature;
[0085] S510, judging whether the indoor return air temperature is greater than the first preset temperature or not, if yes, executing step S511, otherwise, re-executing step S509;
[0086] S511, increasing the rotating speed of the exhaust air fan and / or the rotating speed of the supply air fan.
[0087] In another embodiment of the present application, the target regulation temperature comprises a target condensing temperature, and the current regulation temperature comprises a current condensing temperature when the air conditioning device is in the heating mode, and the controlling the air conditioning device according to the target regulation temperature comprises: reducing the rotating speed of the indoor unit fan and the rotating speed of the compressor according to the target condensing temperature, so as to make the current condensing temperature of the air conditioning device equal to the target condensing temperature.
[0088] Specifically, the target regulation temperature in the embodiment is the target condensing temperature, and the embodiment can specifically reduce the rotating speed of the indoor unit fan and the rotating speed of the compressor, i.e., reduce the heating capacity, in the process of regulating the air conditioning device to make the current regulation temperature of the air conditioning device equal to the target regulation temperature.
[0089] In the embodiment, referring to Figure 1 It can be known that the fresh air device 10 further comprises a heat source 14, the heat source 14 is used for heating the outdoor fresh air, so that the heated outdoor fresh air is guided by the supply air fan 12 to the indoor environment, wherein, when it is determined that the current regulation temperature is in the first preset regulation range, the fresh air device 10 is controlled, comprising: when it is determined that the current condensing temperature is less than or equal to the preset condensing temperature, the heating power of the heat source is reduced, and / or the rotating speed of the exhaust air fan 13 is increased, and / or the rotating speed of the supply air fan 12 is increased.
[0090] Specifically, when it is determined that the current condensing temperature is greater than or equal to the preset condensing temperature, it indicates that the air conditioning device will possibly enter the shutdown state, and then the fresh air device needs to be controlled to increase the load of the air conditioning device, and since the working condition is generally in winter, the indoor and outdoor temperatures will be higher than the outdoor temperature, and the fresh air device is generally in the humidification working condition, i.e., the adsorption material in the adsorption wheel absorbs the moisture in the indoor return air when the indoor return air passes through the adsorption wheel, and the outdoor fresh air is heated by the heat source and then passes through the adsorption wheel to take the moisture in the adsorption wheel to the indoor environment, thereby completing the humidification of the indoor environment. Therefore, in order to increase the load of the air conditioning device, the heating power of the heat source can be reduced, and / or the rotating speed of the exhaust air fan can be increased, and / or the rotating speed of the supply air fan can be increased. In the embodiment, when it is determined that the temperature of the indoor return air is in the second preset regulation range, the fresh air device is controlled, comprising: when the temperature of the indoor return air is less than the second preset temperature, the heating power of the heat source is increased, and / or the rotating speed of the exhaust air fan is reduced, and / or the rotating speed of the supply air fan is reduced.
[0091] Specifically, if the air conditioning device is already in the off state, the temperature of the indoor return air is further acquired, and when the temperature of the indoor return air is less than the second preset temperature, the air conditioning device is prevented from being turned on to perform heating, and thus the heating power of the heat source of the fresh air device can be increased, and / or the rotation speed of the exhaust air side fan can be reduced, and / or the rotation speed of the supply air side fan can be reduced, to reduce the load. It should be noted that all the preset temperatures, preset temperature ranges, etc. in the embodiment can be set by the user himself, and are not specifically limited here.
[0092] As shown in Figure 6 , in this working condition, the energy-saving control of the air conditioning device includes the following steps:
[0093] S601, determining whether the air conditioning device is turned on, if yes, executing step S602, and if not, executing step S609;
[0094] S602, acquiring the temperature and humidity of the indoor return air;
[0095] S603, determining the moisture content of the indoor environment;
[0096] S604, determining the target condensing temperature;
[0097] S605, reducing the rotation speed of the indoor unit fan and the rotation speed of the compressor;
[0098] S606, acquiring the current condensing temperature;
[0099] S607, determining whether the current condensing temperature is greater than or equal to the preset condensing temperature, if yes, executing step S608, and if not, re-executing step S605;
[0100] S608, reducing the heating power of the heat source, and / or increasing the rotation speed of the exhaust air side fan, and / or increasing the rotation speed of the supply air side fan;
[0101] S609, acquiring the temperature of the indoor return air;
[0102] S610, determining whether the temperature of the indoor return air is less than the second preset temperature, if yes, executing step S611, and if not, re-executing step S609;
[0103] S611, increasing the heating power of the heat source, and / or reducing the rotation speed of the exhaust air side fan, and / or reducing the rotation speed of the supply air side fan.
[0104] In summary, the control method of the air conditioning system in the embodiment of the application can control the indoor temperature through the linkage of the fresh air device and the air conditioning device, reduce the energy consumption of the air conditioning device, and improve the user experience.
[0105] Further, the present application provides a computer readable storage medium, having stored thereon a control program of an air conditioning system, which, when executed by a processor, implements the control method of the air conditioning system according to the above embodiment.
[0106] The computer readable storage medium according to the embodiment of the present application, by executing the control program of the air conditioning system stored thereon by a processor, can effectively reduce the energy consumption of the air conditioning equipment and improve the user experience.
