[0062] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0063] An embodiment of the present invention provides an air conditioning system.

[0064] In the embodiment of the present invention, with reference to Figure 1, the air conditioning system includes a control device 100, an air conditioner 200, a fresh air unit 300, and a humidifier 400. The air conditioner 200, the fresh air unit 300, and the humidifier 400 are all connected to the control device 100.

[0065] In this embodiment, the air conditioner 200 is a multi-connected air conditioner, and the air conditioner 200 is used to adjust the temperature of at least two indoor spaces. The multi-connected air conditioner includes at least two indoor units, which are respectively arranged in different indoor spaces to adjust the air in different indoor spaces. Among them, each indoor unit includes an indoor heat exchanger and a control valve connected in series with the indoor heat exchanger, and an indoor fan is correspondingly arranged for the indoor heat exchanger. In some embodiments, the air conditioner 200 can also be an air conditioner 200 independently arranged in a space, such as a cabinet air conditioner, a window air conditioner, a wall-mounted air conditioner, etc.

[0066] In this embodiment, the fresh air unit 300 can introduce outdoor fresh air into the room and discharge the indoor air outdoors. The fresh air unit 300 is used to adjust the fresh air of at least two indoor spaces. The fresh air unit 300 can include more than one air outlet module, which are respectively arranged in different indoor spaces to adjust the air in different indoor spaces. In some embodiments, the fresh air unit 300 can also be a fresh air device independently arranged in a space.

[0067] In this embodiment, the humidifier 400 is used to increase the humidity of the indoor space. In this embodiment, the humidifier can be used to adjust the humidity of at least two indoor spaces. The humidifier 400 can include more than one sub-humidification module, which are respectively arranged in different indoor spaces to increase the humidity of different indoor spaces.

[0068] In this embodiment, the humidifier 400 is a device independently arranged from the air conditioner 200 and the fresh air unit 300. In other embodiments, the humidifier 400 can be built into the air conditioner 200, or the humidifier 400 can be built into the fresh air unit 300.

[0069] Further, referring to Figure 1 , the air conditioning system further includes an environment detection module 500 connected to the control device 100, which can include an indoor detection module and / or an outdoor detection module, and is used to detect the air state parameters (such as temperature, air pressure, humidity, etc.) indoors and / or outdoors. Among them, when the air conditioner 200 is a multi-connected air conditioner, an indoor detection module can be set for each indoor unit, and specifically, the indoor detection module can be arranged at the air return opening of the indoor unit.

[0070] Further, referring to Figure 1 , the air conditioning system further includes a formaldehyde detection module 600 connected to the control device 100, which can be used to detect the formaldehyde state parameters of the indoor space, such as formaldehyde concentration, etc.

[0071] In the embodiment of the present invention, referring to Figure 1, the control device 100 of the air conditioning system includes: a processor 1001, such as a CPU, a memory 1002, and a timer 1003. Among them, these components are connected and communicate with each other through a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0072] Those skilled in the art can understand that Figure 1 the device structure shown in

[0073] does not constitute a limitation on the device, and may include more or fewer components than shown in the figure, or combine some components, or have different component arrangements. Figure 1 As shown in

[0074] In Figure 1 the device shown, the processor 1001 can be used to call the control program of the air conditioning system stored in the memory 1002 and execute the relevant step operations of the control method of the air conditioning system in the following embodiments.

[0075] The embodiment of the present invention also provides a control method for an air conditioning system, which is applied to the above air conditioning system.

[0076] Referring to Figure 2 , an embodiment of the control method of the air conditioning system of the present application is proposed. In this embodiment, the control method of the air conditioning system includes:

[0077] Step S10, obtaining the required heating capacity when removing formaldehyde from the target space regulated by the air conditioning system;

[0078] The required heating capacity is specifically the heating capacity provided by the air conditioning system required for the target space to reach the target state from the current state when reaching the target formaldehyde removal efficiency. The required heating capacity here can be determined according to the parameters input by the user or according to the actual state of the monitored target space.

[0079] The target space is specifically a target space with a formaldehyde removal requirement. The target space can be determined according to the user's instruction, or all the target spaces regulated by the air conditioner can be used as the target space when receiving the user's formaldehyde removal instruction.

[0080] When there are more than one target space regulated by the air conditioning system, the required heating capacity corresponding to each target space can be obtained.

[0081] Step S20: Determine the energy-saving formaldehyde removal mode of the air conditioning system according to the required heating capacity. In the energy-saving formaldehyde removal mode, the air conditioner operates in heating mode. The humidification amount of the humidifier and the heating capacity of the air conditioner in the energy-saving formaldehyde removal mode corresponding to different required heating capacities are different.

[0082] Different energy-saving formaldehyde removal modes correspond to different combinations of humidification amounts and heating capacities. In the combinations corresponding to the energy-saving formaldehyde removal modes, the humidification amount and the heating capacity are negatively correlated. That is, the larger the humidification amount corresponding to the energy-saving formaldehyde removal mode, the smaller the corresponding heating capacity; the smaller the humidification amount corresponding to the energy-saving formaldehyde removal mode, the larger the corresponding heating capacity.

[0083] The minimum value of the humidification amount or the heating capacity corresponding to the energy-saving formaldehyde removal mode can be 0.

[0084] In an implementation manner of this embodiment, at least two preset formaldehyde removal modes can be preset. In the preset formaldehyde removal modes, the air conditioner operates in heating mode and the fresh air fan operates for ventilation. Different preset formaldehyde removal modes correspond to different preset humidification amounts and different preset heating capacities. One of the most energy-saving preset formaldehyde removal modes can be determined from at least two preset formaldehyde removal modes as the energy-saving formaldehyde removal mode according to the required heating capacity.

[0085] In another implementation manner of this embodiment, a corresponding relationship between the required heating capacity and the humidification amount and heating capacity that achieve the energy-saving effect can be established in advance. This corresponding relationship can include calculation formulas, mapping relationships, etc. Based on this corresponding relationship, the humidification amount and heating capacity in the energy-saving formaldehyde removal mode corresponding to the current required heating capacity can be determined. For example, by substituting the required heating capacity into a preset formula, the target humidification amount and the target heating capacity are calculated. The energy-saving formaldehyde removal mode includes the air conditioner inputting the target heating capacity into the target space and the humidifier inputting the target humidification amount into the target space.

[0086] In this embodiment, if the air conditioning system is used to adjust the air in more than one target space, the energy-saving formaldehyde removal mode here can be determined according to the required heating capacities of all target spaces. Specifically, the sum of all required heating capacities can be determined as the total heating capacity. One of the most energy-saving preset formaldehyde removal modes can be determined from at least two preset formaldehyde removal modes as the energy-saving formaldehyde removal mode according to the total heating capacity. Alternatively, the total heating capacity is substituted into the corresponding relationship between the required heating capacity and the humidification amount and heating capacity that achieve the energy-saving effect to obtain the target humidification amount and the target heating capacity in the energy-saving formaldehyde removal mode.

[0087] Step S30: Control the air conditioning system to operate in the energy-saving formaldehyde removal mode.

[0088] Control the air conditioner to operate in heating mode and control the humidifier to operate for humidification according to the determined energy-saving formaldehyde removal mode.

[0089] Further, in this embodiment, the air conditioning system further includes a fresh air unit, and the energy-saving formaldehyde removal mode further includes the fresh air unit operating for ventilation. Then, the air conditioner can be controlled to operate in heating mode, the humidifier can be controlled to operate for humidification, and the fresh air unit can be controlled to operate for ventilation according to the determined energy-saving formaldehyde removal mode. The ventilation volume during the ventilation process of the fresh air unit can be a preset ventilation volume, or can be determined according to the actual operating conditions of the system. Specifically, the ventilation volume of the fresh air unit here can be determined according to the indoor air state parameters and the outdoor air state parameters.

[0090] A control method for an air conditioning system provided by an embodiment of the present invention. During the formaldehyde removal process, in addition to using the air conditioner to raise the temperature, the humidifier can also be used for humidity adjustment. Different energy-saving formaldehyde removal modes can be selected according to different required heating capacities when meeting the demand for formaldehyde removal in the target space, so as to ensure that the humidification amount and the heating capacity are coordinated to adjust the indoor environment state, improve the formaldehyde release rate to meet the formaldehyde removal demand, and compared with using only temperature adjustment to meet the formaldehyde removal demand, the total operating power of the humidifier and the air conditioner can be effectively reduced, so as to meet the formaldehyde removal demand and save energy consumption at the same time, thereby improving the energy efficiency of the system.

[0091] Further, in this embodiment, step S10 includes: obtaining the indoor temperature of the target space and the target formaldehyde removal temperature; determining the required heating capacity according to the indoor temperature and the target formaldehyde removal temperature.

[0092] Specifically, the required heating capacity here can be determined according to the temperature difference value between the indoor temperature and the target formaldehyde removal temperature.

[0093] In this embodiment, the air conditioning system is used to adjust the air in more than one target space. Determine the temperature difference value between the indoor temperature and the target formaldehyde removal temperature of each target space adjusted by the air conditioning system; determine the required heating capacity according to all the temperature difference values. Specifically, the sub-heating capacity required for each space corresponding to each temperature difference value can be determined, and the sum of all sub-heating capacities is determined as the required heating capacity.

[0094] In this embodiment, through the above method, the required heating capacity of the space adjusted by the air conditioning system can be accurately obtained, so as to accurately select the energy-saving formaldehyde removal mode, further ensure the formaldehyde removal effect and save the energy consumption of the system at the same time.

[0095] Further, based on the above embodiment, another embodiment of the control method of the air conditioning system of the present application is proposed. In this embodiment, referring to Figure 3 , step S20 includes:

[0096] Step S21, when the required heating capacity is less than the preset heating capacity, determine the first formaldehyde removal mode as the energy-saving formaldehyde removal mode;

[0097] Step S22: When the required heating capacity is greater than or equal to the preset heating capacity, determine that the second formaldehyde removal mode is the energy-saving formaldehyde removal mode;

[0098] Wherein, in the first formaldehyde removal mode, the humidifier is turned off (at this time, the air conditioner operates in heating mode), in the second formaldehyde removal mode, the humidifier is controlled to operate according to the set humidity (at this time, the air conditioner operates in heating mode), and the heating capacity of the first formaldehyde removal mode is greater than that of the second formaldehyde removal mode.

[0099] The preset heating capacity is specifically the critical heating capacity when the optimal energy consumption of the air conditioning system in the first formaldehyde removal mode is equal to the optimal energy consumption of the air conditioning system in the second formaldehyde removal mode when the target space reaches the target formaldehyde removal effect. Among them, the optimal energy consumption can be understood as the minimum energy consumption estimated based on experimental data and the rated capacity of the air conditioning system.

[0100] Furthermore, before step S20, it also includes: determining the preset heating capacity according to the rated heating capacity of the outdoor unit of the air conditioner, the rated heating capacity of the indoor unit of the air conditioner, and the rated humidification capacity of the humidifier. Specifically, the rated heating capacity of the outdoor unit can be determined according to the model of the outdoor unit, the rated heating capacity can be determined according to the model of the indoor unit, and the rated humidification capacity can be determined according to the model of the humidifier. When there are more than one indoor unit in the air conditioner, the preset heating capacity can be determined according to the rated heating capacity of the outdoor unit, the rated heating capacity of the indoor unit, the number of indoor units, and the rated humidification capacity of the humidifier.

[0101] During the process of controlling the humidifier to operate according to the set humidity, the ambient temperature and / or ambient humidity of the environment where the air conditioning system is located can be obtained, and the humidifier is controlled to operate according to the ambient humidity and the set temperature and / or according to the ambient temperature and the set temperature.

[0102] In this embodiment, when the required heating capacity is less than the preset heating capacity, a smaller heating capacity is required indoors to achieve the target formaldehyde removal effect. At this time, when the air conditioner is used alone for heating, the power is small to achieve the target formaldehyde removal effect. If the humidifier is turned on, it will cause an increase in the total power of the system. Therefore, adopting the first formaldehyde removal mode to control the system operation is beneficial to achieving the target formaldehyde removal effect while reducing the system energy consumption; when the required heating capacity is greater than or equal to the preset heating capacity, a large heating capacity of the air conditioner is required to ensure that the indoor reaches the target formaldehyde removal effect. When the air conditioner is used alone for heating, the power of the system will be very large. Therefore, adopting the second formaldehyde removal mode to control the system operation, through the humidifying effect of the humidifier, it is ensured that the air conditioner can output a smaller heating capacity and the indoor can also reach the target formaldehyde removal effect. The energy consumption of the humidifier for humidification is much smaller than the energy consumption required for increasing the heating capacity of the air conditioner. Compared with using the air conditioner alone for heating to achieve the target formaldehyde removal effect, the total energy consumption of the system can be effectively reduced.

[0103] Further, in this embodiment, the step of controlling the air conditioning system to operate in the energy-saving formaldehyde removal mode includes: when the energy-saving formaldehyde removal mode is the first formaldehyde removal mode, controlling the humidifier to be turned off, and controlling the air conditioner to operate in heating mode according to the required heating capacity and the first target formaldehyde removal temperature; when the energy-saving formaldehyde removal mode is the second formaldehyde removal mode, controlling the humidifier to operate according to the set humidity, and controlling the air conditioner to operate in heating mode according to the preset heating capacity and the second target formaldehyde removal temperature; wherein, the first target formaldehyde removal temperature is greater than the second target formaldehyde removal temperature.

[0104] The first target formaldehyde removal temperature and the second target formaldehyde removal temperature are the target temperatures required in the target space during the formaldehyde removal process.

[0105] The humidification amount when the humidifier is turned on can be a preset humidification amount, or can be determined according to the actual operating conditions of the system. Specifically, the humidification amount of the humidifier here can be determined according to the indoor air state parameters and the outdoor air state parameters.

[0106] Controlling the air conditioner to operate in heating mode according to the required heating capacity and the first target formaldehyde removal temperature includes: controlling the compressor of the air conditioner to operate according to the required heating capacity, and controlling the indoor unit of the air conditioner to operate according to the first target formaldehyde removal temperature.

[0107] Controlling the air conditioner to operate in heating mode according to the preset heating capacity and the second target formaldehyde removal temperature includes: controlling the compressor of the air conditioner to operate according to the preset heating capacity, and controlling the indoor unit of the air conditioner to operate according to the second target formaldehyde removal temperature.

[0108] The set humidity in the first formaldehyde removal mode and the second formaldehyde removal mode can be the same or different.

[0109] In this embodiment, in the first formaldehyde removal mode, during the process of turning off the humidifier, the air conditioner is controlled to operate in heating mode according to the actual required heating capacity and the higher first target formaldehyde removal temperature, so as to ensure that the temperature state required to achieve the target formaldehyde removal effect in the room can be reached when the air conditioner operates in heating mode alone, and ensure that the target formaldehyde removal effect can be achieved in the room; in the second formaldehyde removal mode, during the process of turning on the humidifier, the air conditioner is controlled to operate in heating mode according to the preset heating capacity and the lower second target formaldehyde removal temperature, and the deviation between the heat input into the room by the current air conditioner and the required heating capacity is compensated by the additive effect of the humidification amount on the formaldehyde removal efficiency, so as to ensure that the target formaldehyde removal effect can be achieved in the indoor environment.

[0110] Further, based on any of the above embodiments, another embodiment of the control method of the air conditioning system of the present application is proposed. In this embodiment, referring to Figure 4 , the air outlet control process of the air conditioner during the operation of the energy-saving formaldehyde removal mode is as follows:

[0111] Step S31: Obtain the indoor temperature of the target space and the outdoor temperature outside the target space;

[0112] The indoor temperature is specifically detected by the above-mentioned indoor detection module, and the outdoor temperature is specifically detected by the above-mentioned outdoor detection module.

[0113] When the number of target spaces is more than one, the indoor temperature of each target space can be obtained.

[0114] Step S32: Determine the target air volume of the air conditioner according to the indoor temperature and the outdoor temperature;

[0115] Different indoor temperatures and different outdoor temperatures correspond to different target air volumes. When the number of target spaces is more than one, the target air volume of each target space can be determined according to the corresponding indoor temperature and outdoor temperature, or the target air volume of the air conditioner for each target space can be determined according to all indoor temperatures and outdoor temperatures. The target air volumes of different target spaces can be the same or different.

[0116] In one implementation, the first temperature range where the indoor temperature is located can be determined, the second temperature range where the outdoor temperature is located can be determined, and the target air volume corresponding to the target space can be determined according to the first temperature range and the second temperature range.

[0117] In another implementation, the indoor temperature and the outdoor temperature can be substituted into a preset formula to calculate the target air volume corresponding to the target space.

[0118] In yet another implementation, the target air volume corresponding to the target space can be determined according to the temperature difference value between the indoor temperature and the outdoor temperature.

[0119] In still another implementation, the target air volume corresponding to the target space can be determined according to the indoor temperature, the outdoor temperature, and a preset temperature.

[0120] Step S33: Control the air conditioner to operate in heating mode according to the target air volume.

[0121] Control the indoor fan and / or the indoor air deflector of the air conditioner provided in the target space to operate according to the target air volume, so that the air volume input by the air conditioner into the target space can reach the target air volume.

[0122] Among them, during the operation of the air conditioning system in the first formaldehyde removal mode or the second formaldehyde removal mode, the air output of the air conditioner can be controlled according to steps S31 to S33.

[0123] In this embodiment, the heating capacity of the air conditioner is regulated according to the indoor temperature and the outdoor temperature, which is beneficial to ensuring that the heat output by the air conditioner during the fresh air ventilation process can be precisely matched with the heat introduced by the fresh air ventilation to achieve the target heat required for the target formaldehyde removal effect, thereby further improving the formaldehyde release efficiency of the target space while saving system energy consumption.

[0124] Further, in this embodiment, the step of determining the target air volume of the air conditioner according to the indoor temperature and the outdoor temperature includes: when both the indoor temperature and the outdoor temperature are greater than the first preset temperature, determining the first air volume as the target air volume; when at least one of the indoor temperature and the outdoor temperature is less than or equal to the first preset temperature, determining the second air volume as the target air volume; wherein, the first air volume is less than the second air volume.

[0125] The first preset temperatures corresponding to different energy-saving formaldehyde removal modes are different. Specifically, when the energy-saving formaldehyde removal mode is the first formaldehyde removal mode, determining the first temperature as the first preset temperature; when the energy-saving formaldehyde removal mode is the second formaldehyde removal mode, determining the second temperature as the second preset temperature.

[0126] In this embodiment, the first air volume and the second air volume can be fixed air volumes set in advance, or can be the air volumes determined according to the actual operating state of the system. Specifically, the first air volume and the second air volume can be determined according to the temperature difference value between the indoor temperature and the outdoor temperature, the temperature difference value between the indoor temperature and the preset temperature, and the temperature difference value between the outdoor temperature and the preset temperature.

[0127] When the air conditioner adjusts at least two target spaces, adapting to the different relationships between the indoor temperature, the outdoor temperature and the preset temperature corresponding to different spaces, the target air volumes of the air conditioners in different target spaces can be different. In more than one space, the target air volume of the air conditioner in the target space that meets the first condition is the first air volume, and the target air volume of the air conditioner in the target space that meets the second condition is the second air volume. Here, the first condition is that both the indoor temperature and the outdoor temperature are greater than or equal to the first preset temperature, and the second condition is that at least one of the indoor temperature and the outdoor temperature is less than the first preset temperature.

[0128] In this embodiment, by controlling the heating capacity input by the air conditioner to the target space in the above manner, when the indoor and outdoor temperatures are relatively high, the air conditioner inputs a lower heating capacity, which is beneficial to making more use of the outdoor heat source to increase the indoor temperature to ensure the formaldehyde release rate, reducing the heating capacity of the air conditioner to reduce the energy consumption of the air conditioner; when the indoor or outdoor temperature is relatively low, the air conditioner inputs a higher amount of heat to ensure that the indoor temperature is high enough to ensure the efficient release of formaldehyde. Based on this, it is possible to ensure the target formaldehyde removal effect indoors while saving the energy consumption of the air conditioner.

[0129] Further, based on any of the above embodiments, another embodiment of the control method of the air conditioning system of the present application is proposed. In this embodiment, referring to Figure 5 , the air conditioning system further includes a fresh air unit. During the energy-saving formaldehyde removal mode, the fresh air unit operates for ventilation. The steps of controlling the air conditioning system to operate in the energy-saving formaldehyde removal mode further include:

[0130] Step S34, obtain the indoor enthalpy value of the target space and the outdoor enthalpy value outside the target space;

[0131] The indoor enthalpy value can be specifically determined according to the temperature, humidity, and pressure detected by the above indoor detection module, and the outdoor enthalpy value can be specifically determined according to the temperature, humidity, and pressure detected by the above outdoor detection module.

[0132] Step S35, determine the target ventilation volume of the fresh air unit according to the indoor enthalpy value and the outdoor enthalpy value;

[0133] The target ventilation volume is greater than or equal to 0.

[0134] Different indoor enthalpy values and different outdoor enthalpy values correspond to different target ventilation volumes of the fresh air unit. When there is more than one target space, the target ventilation volume of the fresh air unit for each target space is determined correspondingly according to the indoor enthalpy value and the outdoor enthalpy value of each target space.

[0135] In one implementation, the first enthalpy value interval where the indoor enthalpy value is located can be determined, the second enthalpy value interval where the outdoor enthalpy value is located can be determined, and the target ventilation volume of the fresh air unit corresponding to the target space is determined according to the first enthalpy value interval and the second enthalpy value interval.

[0136] In another implementation, the indoor enthalpy value and the outdoor enthalpy value can be substituted into a preset formula to calculate the target ventilation volume of the fresh air unit corresponding to the target space.

[0137] In yet another implementation, the target ventilation volume of the fresh air unit corresponding to the target space can be determined according to the enthalpy difference between the indoor enthalpy value and the outdoor enthalpy value.

[0138] Step S36, control the fresh air unit to operate according to the target ventilation volume.

[0139] Control the supply air fan and / or the exhaust air fan in the fresh air unit to operate according to the target ventilation volume, so that the actual ventilation volume reaches the target ventilation volume.

[0140] Wherein, when the energy-saving formaldehyde removal mode is the first formaldehyde removal mode or the second formaldehyde removal mode, the ventilation operation process of the fresh air unit can be executed according to steps S34 to S36 here.

[0141] In this embodiment, the air volume of the fresh air should be regulated according to the enthalpy values indoors and outdoors, which is beneficial to ensuring that the introduced fresh air volume can be accurately matched with the temperature and humidity required for the efficient release of formaldehyde indoors, and can effectively utilize outdoor air to assist in regulating the environmental state during the formaldehyde removal process in the target space, thereby ensuring the target formaldehyde removal effect while further saving system energy consumption.

[0142] Further, in this embodiment, the step of determining the target ventilation volume of the fresh air machine according to the indoor enthalpy value and the outdoor enthalpy value includes: when the outdoor enthalpy value is greater than or equal to the indoor enthalpy value, determining the first ventilation volume as the target ventilation volume; when the outdoor enthalpy value is less than the indoor enthalpy value and the indoor enthalpy value is greater than the preset enthalpy value, determining the second ventilation volume as the target ventilation volume; when the outdoor enthalpy value is less than the indoor enthalpy value and the indoor enthalpy value is less than or equal to the preset enthalpy value, determining the third ventilation volume as the target ventilation volume;

[0143] In this embodiment, the first ventilation volume is the maximum ventilation volume, the second ventilation volume is the minimum ventilation volume, and the third ventilation volume is 0. In other embodiments, the first ventilation volume may be the maximum ventilation volume, the third ventilation volume is the minimum ventilation volume, and the second ventilation volume is the ventilation volume between the maximum ventilation volume and the minimum ventilation volume.

[0144] In this embodiment, the ventilation volume may be a pre-set ventilation volume or a ventilation volume determined according to the actual operation of the system. For example, the first ventilation volume and the second ventilation volume of the target space can be determined according to the formaldehyde concentration in the target space.

[0145] In this embodiment, when both the indoor and outdoor enthalpy values are relatively small, the fresh air machine is controlled to operate with the minimum third ventilation volume to reduce the loss of indoor heat caused by ventilation, which is beneficial for the target space to have enough heat to rapidly increase the formaldehyde release rate; when the indoor enthalpy value is relatively large but the outdoor enthalpy value is smaller than the indoor enthalpy value, the fresh air machine operates with a lower second ventilation volume, which is beneficial for ensuring that formaldehyde is discharged outdoors while maintaining a relatively high formaldehyde release rate indoors, thereby further improving the formaldehyde removal effect; when the outdoor enthalpy value is greater than the indoor enthalpy value, the fresh air machine is controlled to operate with the maximum first ventilation volume to improve the utilization rate of outdoor heat, reduce the heating output during the system operation, ensure the rapid release of indoor formaldehyde while reducing the formaldehyde removal energy consumption of the system.

[0146] Further, based on any of the above embodiments, another optional embodiment of the control method of the air conditioning system of the present application is proposed. In this embodiment, the air conditioning system further includes a fresh air machine, and the fresh air machine operates with ventilation in the energy-saving formaldehyde removal mode. Refer to Figure 6 , when the energy-saving formaldehyde removal mode includes controlling the humidifier to operate according to the set humidity, the controlling the humidifier to operate according to the set humidity includes:

[0147] Step S37: Obtain the indoor humidity of the target space, the outdoor humidity outside the target space, and the operating state of the fresh air unit.

[0148] The indoor humidity can specifically be detected by the above-mentioned indoor detection module, and the outdoor humidity can specifically be detected by the above-mentioned outdoor detection module.

[0149] The operating state of the fresh air unit includes at least one of the following parameters: the opening degree of the fresh air inlet, the opening degree of the air supply outlet, the air change rate, the rotational speed of the air supply fan, the rotational speed of the exhaust fan, etc.

[0150] Step S38: Control the operation of the humidifier according to the indoor humidity, the outdoor humidity, the operating state, and the set humidity of the humidifier.

[0151] The humidification amounts of the target space corresponding to different indoor humidities, outdoor humidities, operating states, and set humidities are different. When the air conditioning system adjusts more than one target space, the humidification amount corresponding to each target space can be determined according to the indoor humidity, outdoor humidity, operating state of the fresh air unit, and set temperature corresponding to each target space.

[0152] In one implementation, the target humidification amount can be calculated by substituting the indoor humidity, outdoor humidity, operating state, and set humidity into a preset formula, and the operation of the humidifier is controlled according to the target humidification amount.

[0153] In another implementation, the target humidification amount can be determined according to the magnitude relationship between the indoor humidity and the set humidity, the magnitude relationship between the outdoor humidity and the set humidity, and the operating state of the fresh air unit, and the operation of the humidifier is controlled according to the target humidification amount.

[0154] In yet another implementation, the target humidification amount can be determined according to the temperature difference value between the indoor humidity and the outdoor humidity, the temperature difference value between the indoor humidity and the set humidity, and the operating state, and the operation of the humidifier is controlled according to the target humidification amount.

[0155] Among them, during the operation of the air conditioning system in the first formaldehyde removal mode or the second formaldehyde removal mode, the humidification amount of the humidifier can be controlled according to steps S37 to S38.

[0156] In this embodiment, the operation of the humidifier is controlled by combining the indoor and outdoor humidities, the operating state of the fresh air unit, and the set humidity, so as to ensure the effective utilization of the outdoor humidity, and ensure that the humidification effect of the humidifier cooperates with the humidification effect of the moisture introduced by the outdoor fresh air, so that the target space can quickly and accurately reach the humidity environment required for the target formaldehyde removal effect. While removing indoor formaldehyde, the regulatory effect of outdoor air is maximally utilized, and the system energy consumption required to reach the humidity environment for the target formaldehyde removal effect can be reduced, thereby further saving system energy consumption while ensuring the formaldehyde removal effect of the system.

[0157] Further, in this embodiment, the step of controlling the operation of the humidifier according to the indoor humidity, the outdoor humidity, the operating state, and the set humidity includes: when the first condition is met, controlling the humidifier to turn off; when the second condition is met, controlling the operation of the humidifier according to the first humidification amount; when the third condition is met, controlling the operation of the humidifier according to the second humidification amount; when the fourth condition is met, controlling the operation of the humidifier according to the third humidification amount; when none of the first condition, the second condition, the third condition, and the fourth condition is met, controlling the operation of the humidifier according to the fourth humidification amount; wherein, the first condition includes that both the indoor humidity and the outdoor humidity are greater than the set humidity, the second condition includes that the indoor humidity is greater than the set humidity, the outdoor humidity is less than or equal to the set humidity, and the air change rate of the fresh air machine is greater than the preset air change rate, the third condition includes that the indoor humidity is greater than the set humidity, the outdoor humidity is less than or equal to the set humidity, and the air change rate of the fresh air machine is less than or equal to the preset air change rate, the fourth condition includes that the indoor humidity is less than or equal to the set humidity, the outdoor humidity is greater than the set humidity, and the air change rate of the fresh air machine is greater than the preset air change rate, the fourth humidification amount is greater than the first humidification amount and the third humidification amount, and both the first humidification amount and the third humidification amount are greater than the second humidification amount.

[0158] The set humidity can be the target value required for the indoor humidity during the formaldehyde removal process set in advance, or the humidity determined according to the actual formaldehyde removal state of the target space. For example, the set humidity here can be determined according to the difference between the required heating capacity and the preset heating capacity and the difference between the outdoor humidity and the indoor humidity.

[0159] In different energy-saving formaldehyde removal modes, the set humidity and the preset air change rate can be the same or different.

[0160] The first humidification amount, the second humidification amount, the third humidification amount, and the fourth humidification amount can be the humidification amounts set in advance, or the humidification amounts determined according to the actual formaldehyde removal state of the target space. Specifically, the first humidification amount, the second humidification amount, the third humidification amount, and the fourth humidification amount can be determined according to the difference between the indoor humidity and the outdoor humidity, the air change rate of the fresh air machine, and the current indoor temperature, etc.

[0161] In this embodiment, when the first condition is met, the humidifier is turned off, which can ensure the formaldehyde removal effect while further reducing energy consumption; when the second condition is met, humidification is carried out with a relatively large first humidification amount, which is beneficial to maintaining a relatively high humidity state indoors during the fresh air large-volume ventilation process to ensure the formaldehyde removal effect; when the third condition is met, humidification is carried out with a relatively small second humidification amount, which is beneficial to making up for the humidity loss caused by the introduction of fresh air through the humidification amount during the fresh air ventilation process and ensuring that the indoor humidity can be maintained at a relatively high state to ensure the formaldehyde removal effect; when the fourth condition is met, humidification is carried out with a relatively large third humidification amount, which is beneficial to ensuring the combined humidification effect of the humidifier and fresh air, enabling the indoor environment to quickly reach the humidity state required for the target formaldehyde removal effect and effectively ensuring the achievement of the target formaldehyde removal effect; when none of the above conditions are met, the fresh air humidity adjustment effect is small and the indoor humidity also deviates from the requirements of the target formaldehyde removal effect. At this time, humidification is carried out with the largest fourth humidification amount to enable the indoor environment to quickly reach the humidity state required for the target formaldehyde removal effect and effectively ensure the achievement of the target formaldehyde removal effect.
