[0021] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0022] Nowadays, air conditioning systems are installed in various places to control the temperature and humidity of the application places. Some application scenarios do not require high temperature, but have high requirements for humidity. Therefore, how to use air conditioning systems to achieve accurate control of humidity has become an urgent problem to be solved.

[0023] Generally, ordinary comfort air conditioning systems have cooling mode, heating mode, dehumidification mode and air supply mode, and are often used in places where the accuracy requirements for temperature and humidity are not high, such as commercial and household places such as commercial office buildings, theaters, and residential buildings. Constant temperature and humidity process air conditioning has cooling constant temperature and humidity, heating constant temperature and humidity, and air supply mode, and is often used in industrial places with high requirements for temperature and humidity accuracy, such as hospitals, laboratories, industrial workshops, etc. It can maintain the stability of the working environment by controlling the indoor temperature and humidity; in recent years, it has also been promoted to civilian places to provide a more comfortable indoor environment. Whether it is comfort air conditioning or process air conditioning, the air supply mode does not control temperature or humidity, and is only used for indoor air circulation or replacement of fresh air. It is more commonly used in places where there is no high demand for cooling and heating, as well as in transitional seasons.

[0024] However, some civil or industrial and commercial places do not require high temperature but high humidity, such as civil residences during short holidays, furniture malls, electronics factories, explosion-proof factories, etc. For example, in civil air-conditioning systems, if you are away from home for a short holiday, but have valuable wooden furniture at home, you need to ensure a certain humidity (if the humidity is too low, the wooden furniture will crack, and if the humidity is too high, the house will get damp and mold will easily grow), but you do not need to strictly control the temperature.

[0025] If the constant temperature and humidity mode is used, both humidity and temperature must be maintained, which consumes relatively more power. However, if the air supply mode is used, the humidity cannot be controlled. If the dehumidification mode is used, the air conditioning system will be loaded all the time to ensure that the humidity drops. However, the application site cannot be humidified in the dehumidification mode, so it is impossible to accurately control the humidity in the application site.

[0026] In order to solve the above technical problems, the embodiment of the present application provides a control method, which will be described in detail below:

[0027] See also Figure 1 and Figure 2 The embodiment of the present application provides a control method applied to an air conditioning system 100, the air conditioning system 100 includes a humidity adjustment device and a fan 10, and the control method includes:

[0028] Step 011: When the air conditioning system 100 is in the air supply constant humidity mode, the fan 10 is controlled to operate and the current humidity content of the target place is obtained;

[0029] Specifically, the air conditioning system 100 is connected to the target place, the target place is the place where the air conditioning system 100 works, and the air conditioning system 100 is used to adjust the temperature and humidity of the target place. The air conditioning system 100 includes a fan 10 and a humidity adjustment device. The fan 10 is mainly used for air supply, and its function is to increase the air flow in the room. The humidity adjustment device is a device that can be used to adjust the indoor humidity. An air inlet duct 40 and a return air duct 30 are provided between the air conditioning system 100 and the target place. The air inlet duct 40 is connected to the output end of the air conditioning system 100, and the return air duct 30 is connected to the input end of the air conditioning system 100.

[0030] The fan 10 and the humidity adjustment device may both be arranged in the outdoor unit, or the humidity adjustment device may be arranged in the outdoor unit and the fan 10 may be arranged in the indoor unit.

[0031] A human-computer interaction interface 50 (such as a remote control) can be set in the target place. The user can use the human-computer interaction interface 50 to set the air-conditioning mode, set the temperature, set the humidity or set the wind speed, so that the user can issue commands to the air-conditioning system 100 according to the human-computer interaction interface 50 to achieve the purpose of air treatment.

[0032] When the target location has a high control accuracy for humidity and a low control accuracy for temperature, the user can control the air conditioning system 100 to be in the air supply and constant humidity mode using the human-computer interaction interface 50. When the air conditioning system 100 is in the air supply and constant humidity mode, the fan 10 will continue to work to increase the air flow of the target location.

[0033] Humidity refers to the content of water vapor in the air relative to the saturation of water vapor in the air, usually expressed as a percentage. Moisture content refers to the mass of water vapor contained in a unit volume of air, usually expressed in g / m 3 or kg / m 3 To indicate. The air conditioning system 100 needs to adjust the humidity according to the humidity content, so it is necessary to obtain the current humidity content of the target place. For example, a temperature sensor and a humidity sensor can be installed in the target place or in the return air duct 30, so as to obtain the current temperature of the target place using the temperature sensor, and obtain the current humidity of the target place using the humidity sensor. Alternatively, a temperature and humidity sensor 20 can be installed in the target place or in the return air duct 30, so as to directly obtain the current temperature and current humidity of the target place using the temperature and humidity sensor 20.

[0034] Therefore, the current humidity of the target location can be determined based on the current temperature and humidity of the target location, combined with the following formula (1) and formula (2):

[0035] d=622*Pq / (101300-Pq) (1)

[0036]

[0037] in: is the current humidity, T is the current temperature / ℃, and d is the current moisture content.

[0038] In one embodiment, the current temperature and humidity of the target location can be continuously acquired so as to monitor the current moisture content of the target location at all times, thereby facilitating improving the humidity control accuracy of the target location. In another embodiment, the current temperature and humidity of the target location can be acquired at preset intervals, for example, the preset interval is any interval between 1 minute and 3 minutes, preferably the preset interval is 2 minutes, so as to prevent the humidity from being adjusted too frequently, thereby facilitating energy saving.

[0039] Step 012: When the current humidity content exceeds the preset humidity content range, the humidity regulating device is controlled to operate so that the adjusted current humidity content is within the preset humidity content range.

[0040] Specifically, the preset humidity range is determined according to the preset temperature and preset humidity of the target location. The user can set the preset temperature and preset humidity as needed, and then determine the preset humidity based on the above formula (1) and formula (2). After determining the preset humidity, the preset humidity range is determined in combination with the upper deviation and the lower deviation. The sum of the preset humidity and the upper deviation is the maximum value of the preset humidity range, and the difference between the preset humidity and the lower deviation is the minimum value of the preset humidity range. The upper deviation and the lower deviation are deviation values ​​when the gap between the corresponding humidity and the preset humidity is smaller after combining with the preset humidity. The setting of the upper deviation and the lower deviation can be used to prevent the humidity from being adjusted too frequently. Alternatively, the user can also directly determine the preset humidity or the preset humidity range.

[0041] When the current humidity content exceeds the preset humidity content range, the humidity control device can be controlled to operate so that the adjusted current humidity content is within the preset humidity content range. For example, when the current humidity content is less than the minimum value of the preset humidity content range, the humidity control device is controlled to humidify. When the current humidity content is greater than the maximum value of the preset humidity content range, the humidity control device is controlled to dehumidify.

[0042] When the current humidity content is within the preset humidity content range, the humidity regulating device can be controlled to stop running, and only the fan 10 is running at this time to improve the air flow of the target place.

[0043] In this way, the present application actually provides a constant humidity air supply function. In the air supply and constant humidity mode, the present application monitors the humidity of the target place at all times. When the humidity of the target place is too high, the present application will use the humidity adjustment device for dehumidification. When the humidity of the target place is too low, the present application can also use the humidity condition device for humidification. When the humidity of the target place is appropriate, the present application only supplies air. In this way, the air conditioning system 100 can accurately switch between the dehumidification air supply mode, the humidification air supply mode and the air supply mode (i.e., only air supply) according to the current moisture content of the target place, ensuring that the moisture content of the target place can be maintained within the preset moisture content range to improve the humidity control accuracy. At the same time, the present application does not need to strictly control the temperature, so compared with the constant temperature and humidity mode, the present application can further save energy consumption. In this way, the present application can achieve more energy-saving and more intelligent humidity control. Compared with the traditional dehumidification mode, the present application can also achieve humidification, and compared with the traditional air supply mode, the present application can humidify and dehumidify the target place, so the present application can achieve more intelligent humidity control.

[0044] In addition, the present application does not limit the specific structure of the air delivery system. The air delivery system of the present application can be a fresh air system, a return air system or a mixed air system. The air delivery system can also add various functions such as purification, dust removal, sterilization, mildew removal, heat recovery, etc. Therefore, the present application can be applied to direct expansion systems, chilled water systems, fresh air systems, mixed air systems, return air systems, etc. in many scenarios.

[0045] In the control method of the embodiment of the present application, when the air conditioning system 100 is in the air supply constant humidity mode, the fan 10 of the air conditioning system 100 continues to supply air, and the current humidity content of the target place can be obtained at the same time. When the current humidity content of the target place exceeds the preset humidity content range, the air conditioning system 100 will control the humidity control device to operate, for example, when the current humidity content is lower than the minimum value of the preset humidity content range, the humidity control device is controlled to humidify, and when the current humidity content is greater than the maximum value of the preset humidity content range, the humidity control device is controlled to dehumidify, so as to ensure that the current humidity content of the adjusted target place is within the preset humidity content range. When the current humidity content is within the preset humidity content range, the air conditioning system 100 only supplies air. In this way, the air conditioning system 100 can accurately switch between the dehumidification air supply mode, the humidification air supply mode and the air supply mode according to the current humidity content of the target place, so as to ensure that the humidity content of the target place can be kept within the preset humidity content range, thereby realizing more intelligent and more accurate humidity control.

[0046] See also Figure 2 and Figure 3 In some embodiments, the humidity regulating device includes a dehumidifying device 60 and a humidifying device 70. Step 012: when the current humidity content exceeds the preset humidity content range, controlling the humidity regulating device to operate includes:

[0047] Step 0121: When the current moisture content is less than the minimum value of the preset moisture content range, control the humidification device 70 to operate;

[0048] Step 0122: When the current moisture content is greater than the maximum value of the preset moisture content range, control the dehumidification device 60 to operate.

[0049] Specifically, the humidification method of the humidifier 70 includes but is not limited to dry steam humidification, electrode humidification, and mist humidification. The humidifier 70 can spray water vapor to the gas to increase the humidity of the target location. The dehumidifier 60 can condense the moisture in the gas entering the dehumidifier 60 into water droplets by lowering the temperature of the internal space of the dehumidifier 60, and then discharge the dried gas into the target location. After such a cycle, the dehumidification effect can be achieved.

[0050] For example, the humidity control device includes a humidifying device 70 and a dehumidifying device 60. The humidifying device 70 can be used for humidification, and the dehumidifying device 60 can be used for dehumidification. The humidifying device 70 and the dehumidifying device 60 can be two different components in one humidity control device, that is, one humidity control device can achieve humidification and dehumidification at the same time, or the humidifying device 70 and the dehumidifying device 60 are two separate devices.

[0051] Therefore, when the current humidity is less than the minimum value of the preset humidity range, the humidifier 70 is controlled to operate, that is, the humidifier 70 is controlled to humidify. When the current humidity is greater than the maximum value of the preset humidity range, the dehumidifier 60 is controlled to operate, that is, the dehumidifier 60 is controlled to dehumidify. When the current humidity is within the preset humidity range, the humidifier 70 and the dehumidifier 60 can be controlled to stop operating, and only the fan 10 is operated at this time to improve the air flow of the target location.

[0052] Proportional-Integral-Derivative control (PID) can be performed when controlling the operation of the humidifier 70 and the dehumidifier 60. PID control compares the deviation between the given value and the actual output value, and uses a linear combination of proportion, integration and differentiation to calculate the control amount, thereby controlling the controlled object.

[0053] Therefore, when the current humidity content is less than the minimum value of the preset humidity content range, the target humidification amount of the humidifier 70 is determined according to the current humidity content and the preset humidity content range. For example, the current humidity content is used as the actual output value, and the preset humidity content in the preset humidity content range is used as the given value. Then, by comparing the deviation between the current humidity content and the preset humidity content, the control amount target humidification amount is calculated by combining a linear combination of proportion, integration and differentiation. Then, the operation of the humidifier 70 is controlled according to the target humidification amount, so as to improve the control accuracy of the humidifier 70 over humidity.

[0054] When the current moisture content is greater than the maximum value of the preset moisture content range, the target dehumidification amount of the dehumidification device 60 is determined according to the current moisture content and the preset moisture content range, for example, the current moisture content is used as the actual output value, and the preset moisture content in the preset moisture content range is used as the given value, and then the target dehumidification amount of the control quantity is calculated by comparing the deviation between the current moisture content and the preset moisture content and combining the linear combination of proportion, integration and differentiation, and then the operation of the dehumidification device 60 is controlled according to the target dehumidification amount, so as to improve the control accuracy of the dehumidification device 60 over the humidity.

[0055] In this way, the humidity control accuracy of the humidifying device 70 and the dehumidifying device 60 can be controlled by PID adjustment to ensure that the current humidity content of the target place after adjustment can be within the preset humidity content range.

[0056] Of course, the humidifier 70 and the dehumidifier 60 may also have only one operating gear. When it is necessary to control the operation of the humidifier 70 or the dehumidifier 60, it is directly operated according to the corresponding operating gear, and the current humidity content of the target place is continuously detected during the operation. Once the current humidity content is within the preset humidity content range, the humidifier 70 or the dehumidifier 60 is controlled to stop operating. Alternatively, the humidifier 70 and the dehumidifier 60 are provided with multiple operating gears, and different operating gears correspond to different humidity contents. The target operating gear of the humidifier 70 or the dehumidifier 60 can be determined according to the current humidity content, and then it can be operated according to the target operating gear. In this way, the current humidity content of the target place after adjustment can also be within the preset humidity content range.

[0057] It should be noted that the control modes of the humidifier 70 and the dehumidifier 60 may be the same or different, and are not limited to each other. For example, the humidifier 70 may use PID regulation, and the dehumidifier 60 may have multiple operating gears, or both the humidifier 70 and the dehumidifier 60 may use PID regulation.

[0058] In this way, the operation of the humidifying device 70 and the dehumidifying device 60 can be accurately controlled according to the current humidity content and the preset humidity content range to ensure that the current humidity content of the target place can be maintained within the preset humidity content range.

[0059] See also Figure 2 and Figure 4 In some embodiments, the air conditioning system 100 includes a temperature regulating device, and the control method includes:

[0060] Step 013: During the operation of the humidifying device 70, the current temperature of the target location is obtained;

[0061] Step 014: When the current temperature is lower than the first preset temperature threshold, control the temperature adjustment device to heat;

[0062] Step 015: When the current temperature is higher than the second preset temperature threshold, the temperature regulating device is controlled to stop running.

[0063] Specifically, the air conditioning system 100 also includes a temperature regulating device, which can regulate the indoor temperature of the target location. The indoor temperature will affect the humidification effect. When the indoor temperature is low, the humidification effect is greatly reduced. Too low temperature has little effect on the dehumidification effect. Therefore, at least during the operation of the humidification device 70, it is necessary to obtain the current temperature of the target location so as to adjust the temperature of the target location in a timely manner.

[0064] The first preset temperature threshold is the minimum value of the temperature of the target place when the humidification effect meets expectations. Once the temperature of the target place is lower than the first preset temperature threshold, it means that the humidification effect of the humidification device 70 on the target place is poor. The second preset temperature threshold is the minimum temperature at which the humidification effect meets expectations and the temperature of the target place does not drop quickly below the first preset temperature threshold after the temperature adjustment device stops heating. For example, the first preset temperature threshold is 18°C ​​and the second preset temperature threshold is 20°C.

[0065] During the operation of the humidifying device 70, the current temperature of the target place can be obtained through the temperature and humidity sensor 20 or the temperature sensor. When the current temperature is lower than the first preset temperature threshold, it can be considered that the temperature is too low at this time, resulting in a poor humidification effect. Therefore, the temperature regulating device can be controlled to heat so that the temperature of the target place rises, so as to improve the humidification effect of the humidifying device 70, thereby increasing the humidity rising speed of the target place. When the current temperature is higher than the second preset temperature threshold, it can be considered that the temperature has little effect on the humidification effect at this time, and the temperature regulating device is controlled to stop running to reduce the energy consumption of the temperature regulating device during operation. Alternatively, when the humidifying device 70 stops running, the temperature regulating device can be controlled to stop running to reduce the energy consumption of the temperature regulating device during operation.

[0066] In this way, at least during the operation of the humidifier 70, the current temperature of the target place can be obtained so as to timely increase the current temperature of the target place and prevent the current temperature from being too low to reduce the humidification effect of the humidifier 70. Thus, the temperature regulating device can be used to assist the operation of the humidifier 70 to ensure that the humidification effect of the humidifier 70 is better.

[0067] See also Figure 2 and Figure 5 In some embodiments, the control method comprises:

[0068] Step 016: During the operation of the dehumidification device 60, the current temperature of the target location is obtained;

[0069] Step 017: When the current temperature is lower than the third preset temperature threshold, control the temperature adjustment device to heat;

[0070] Step 018: When the current temperature is higher than the fourth preset temperature threshold, the temperature regulating device is controlled to stop running.

[0071] Specifically, the dehumidification process will cause the temperature in the target place to decrease. If the temperature drops too low, it may affect the user's physical sensation in the target place or affect the safety of items stored in the target place. For example, the target place is used to store wood, and the temperature requirement of the warehouse for wood storage is usually between 15°C and 25°C. If the temperature is lower than 15°C, the wood may be damaged. The third preset temperature threshold is the lowest temperature when dehumidification is performed, when the user feels better or the safety of the items stored in the target place is higher. The fourth preset temperature threshold is the lowest temperature when dehumidification is performed, when the user feels better or the safety of the items stored in the target place meets expectations, and after the temperature adjustment device stops heating, the temperature of the target place will not quickly drop to a temperature below the third preset temperature threshold.

[0072] During the operation of the dehumidification device 60, the current temperature of the target place can be obtained through the temperature and humidity sensor 20 or the temperature sensor. When the current temperature is lower than the third preset temperature threshold, it can be considered that the temperature is too low at this time, resulting in poor physical sensation of the user in the target place or affecting the safety of the items stored in the target place. Therefore, the temperature adjustment device can be controlled to heat up so that the temperature of the target place rises, so as to improve the physical sensation of the user in the target place or the safety of the items stored in the target place. When the current temperature is higher than the fourth preset temperature threshold, it can be considered that the physical sensation of the user in the target place or the safety of the items stored in the target place is high, and the temperature adjustment device is controlled to stop running to reduce the energy consumption of the temperature adjustment device during operation. Alternatively, when the dehumidification device 60 stops running, the temperature adjustment device can be controlled to stop running to reduce the energy consumption of the temperature adjustment device during operation.

[0073] It should be noted that if the target place only has high requirements for humidity and not for temperature, the temperature reduction during the dehumidification process will not have any impact on the target place. In this case, temperature adjustment will only be performed during the humidification process, and no temperature adjustment will be performed during the dehumidification process, so as to further reduce the energy consumption of the temperature adjustment equipment during operation during the dehumidification process, while ensuring the humidification effect during the humidification process.

[0074] In this way, during the operation of the dehumidification device 60, temperature adjustment can also be performed to improve the user's physical sensation in the target location or the safety of items stored in the target location.

[0075] See also Figure 2 , Figure 6 and Figure 7In some embodiments, the humidity adjustment device includes a dehumidifier 60 and a humidifier 70, the dehumidifier 60 includes a temperature control function and a dehumidification function, the temperature adjustment device includes a dehumidifier 60 and a heating device 80, the humidifier 70 is located between the dehumidifier 60 and the output end of the air conditioning system 100, and the heating device 80 is located between the humidifier 70 and the output end of the air conditioning system 100, step 014: when the current temperature is lower than the first preset temperature threshold, controlling the temperature adjustment device to heat, including:

[0076] Step 0141: When the current temperature is lower than the first preset temperature threshold, control at least one of the dehumidification device 60 and the heating device 80 to perform heating;

[0077] Step 017: When the current temperature is lower than the third preset temperature threshold, controlling the temperature adjustment device to heat, including:

[0078] Step 0171: When the current temperature is lower than the third preset temperature threshold, control the heating device 80 to heat.

[0079] Specifically, the dehumidifier 60 can have both temperature control function and dehumidification function. For example, the dehumidifier 60 is a cooling or heating coil, wherein the cooling and heating coil can be a water coil, in which case the coil flows with a secondary coolant, and the cooling and heating coil can also be a fluorine coil, in which case the coil flows with a refrigerant, and the temperature of the working fluid (i.e., the refrigerant or secondary coolant) of the dehumidifier 60 can be changed, so that the dehumidifier 60 can be heated or cooled, so in fact, the dehumidifier 60 is also a temperature regulating device. For example, the evaporator and condenser commonly seen in the air-conditioning system 100 can be understood as fluorine coils, and the temperature of the refrigerant flowing in the coil can be changed by controlling the operation of the evaporator and the condenser. Or in the case where the dehumidifier 60 is a water coil, the air-conditioning system 100 can be additionally provided with an evaporator and a condenser. The secondary coolant is cooled by the refrigerant in the evaporator, and then sent to the cooling device to absorb the heat of the cooled object, and then returned to the evaporator to be cooled by the refrigerant again, and the temperature of the secondary coolant can be controlled by controlling the operation of the evaporator and the condenser. After the temperature of the working fluid in the dehumidifier 60 is lowered, the gas passing through the dehumidifier 60 exchanges heat with the dehumidifier 60, so that the moisture in the gas is condensed into water, thereby completing the dehumidification. Therefore, dehumidification can be completed by lowering the temperature of the dehumidifier 60, so that the dehumidifier 60 can have both temperature control function and dehumidification function.

[0080] The air conditioning system 100 may also be provided with a heating device 80, which is mainly used for compensating and increasing the temperature, and is generally electric heating, and other reheating types may also be used. The humidifying device 70 is located between the dehumidifying device 60 and the output end of the air conditioning system 100, and the heating device 80 is located between the humidifying device 70 and the output end of the air conditioning system 100, that is, from the input end of the air conditioning system 100 toward the output end of the air conditioning system 100, the air conditioning system 100 includes a dehumidifying device 60, a humidifying device 70 and a heating device 80. In this way, the gas after being cooled and dehumidified by the dehumidifying device 60 can be heated by heating of the heating device 80. In some embodiments, the fan 10 may be arranged between the dehumidifying device 60 and the input end of the air conditioning system 100, or the fan 10 may be arranged in an indoor unit of the air conditioning system 100 located in the target place.

[0081] When the current humidity control mode is humidification, if the current temperature is lower than the first preset temperature threshold, it can be considered that heating is required at this time to improve the humidification effect. Therefore, at least one of the dehumidification device 60 or the heating device 80 can be controlled to heat, for example, the dehumidification device 60 is controlled to heat, or the heating device 80 is controlled to heat, or the dehumidification device 60 and the heating device 80 are controlled to heat at the same time, so as to improve the heating efficiency.

[0082] When the current humidity control mode is dehumidification, if the current temperature is lower than the third preset temperature threshold, it can be considered that the temperature is low and needs to be heated. However, the dehumidification device 60 needs to perform the dehumidification function. When the dehumidification device 60 performs the dehumidification function, the temperature of the working fluid therein is low and the gas cannot be heated. Therefore, at this time, only the heating device 80 can be controlled to heat the gas dehumidified by the dehumidification device 60, so as to ensure that the air conditioning system 100 can dehumidify on the one hand, and on the other hand, ensure that the temperature of the dehumidified gas can be controlled.

[0083] In this way, the dehumidifier 60 has both the temperature adjustment function and the dehumidification function, and the heating device 80 has the heating function. When the current temperature is low, it is necessary to select a device for heating according to the current humidity control mode. When the current humidity control mode is humidification, at least one of the dehumidifier 60 and the heating device 80 can be controlled to heat. When the current humidity control mode is dehumidification, the heating device 80 is controlled to heat, thereby ensuring that temperature control can be achieved during both dehumidification and humidification.
