By adopting the system for dehumidification provided by the embodiment of the disclosure, the indoor environment can be cooled and dehumidified by matching the air conditioner 200 with the dehumidifier 300, because the dehumidification capacity of the air conditioner 200 is related to the evaporation pressure of the evaporator thereof, the high and low evaporation pressures of the evaporator concern the high and low evaporator tube temperatures, the lower the tube temperature of the evaporator, the stronger the dehumidification capacity of the air conditioner 200, and therefore the lower the evaporation pressure, the lower the tube temperature of the evaporator, the stronger the dehumidification capacity of the air conditioner 200, and when the air conditioner 200 is in normal operation, the suction pressure and the evaporation pressure of the compressor are almost the same, the dehumidification capacity of the air conditioner 200 can be more accurately reflected according to the high and low suction pressure of the compressor of the air conditioner 200, so the operation modes of the air conditioner 200 and the dehumidifier 300 are controlled according to the magnitude relation between the suction pressure and the target evaporation pressure of the compressor of the air conditioner 200, the air conditioner 200 and the humidity conditioner 300 can be matched more accurately, so that the humidity load of the indoor environment can be eliminated more efficiently, the comfort of the indoor environment is improved, and the energy consumption is reduced.
Alternatively, the controller 400 may be independent of the air conditioner 200 and the humidity conditioner 300, and may control the processors of the air conditioner 200 and the humidity conditioner 300, and the controller 400 may be mounted on the air conditioner 200 or the humidity conditioner 300. Like this, can be through the running state of controller 400 simultaneous control air conditioner 200 and damping machine 300, better adjust the humiture of indoor environment, install controller 400 is integrated on air conditioner 200 or damping machine 300 moreover, can reduce the occupation of the space of this system.
Optionally, the system for dehumidifying further comprises: a pressure sensor 500. The pressure sensor 500 is used to detect the suction pressure of the compressor of the air conditioner 200. In this way, the controller 400 may obtain the suction pressure of the compressor of the air conditioner 200 detected by the pressure sensor 500, and then control the operation of the air conditioner 200 and the humidity conditioner 300 according to the operation modes of the air conditioner 200 and the humidity conditioner 300 corresponding to the suction pressure in different preset pressure intervals, that is, the operation modes of the air conditioner 200 and the humidity conditioner 300 are controlled according to the magnitude relation between the suction pressure of the compressor of the air conditioner 200 and the target evaporation pressure, so as to more accurately cool and dehumidify the indoor environment, more efficiently eliminate the humidity load of the indoor environment, improve the comfort of the indoor environment, and reduce energy consumption.
In some examples, the pressure sensor 500 may be a pressure gauge, and the pressure gauge is installed at the air suction port of the compressor of the air conditioner 200, so that the air suction pressure of the compressor of the air conditioner 200 can be detected in real time.
Optionally, the system for dehumidifying further comprises: an air quality sensor 600. The air quality sensor 600 is used to detect the quality of the outdoor environment and the indoor environment.

As shown in connection with fig. 3-8, in some alternative embodiments, the humidity conditioner 300 includes: a housing 310, a moisture absorbing rotor 320, and a first baffle 330. The interior of the housing 310 defines a cavity; the moisture absorption rotary disc 320 is rotatably arranged in the cavity, a circulation cavity 311 is defined between the upper end surface of the moisture absorption rotary disc 320 and the inner wall of the cavity, and the lower end surface of the moisture absorption rotary disc 320 is provided with a first air inlet end 321, a first air outlet end 322, a second air inlet end 323 and a second air outlet end 324; the first partition 330 is disposed in the circulation chamber 311 and divides the circulation chamber 311 into a first chamber 312 and a second chamber 313. Thus, because the moisture in the air flow is absorbed when the air flow at normal temperature passes through the moisture absorption rotary disc 320, and the moisture in the moisture absorption rotary disc 320 is regenerated and released into the air flow when the heated air flow passes through the moisture absorption rotary disc 320, by utilizing the characteristic of the moisture absorption rotary disc 320, the moisture absorption rotary disc 320 is driven to continuously rotate below the first chamber 312 and the second chamber 313, and one of the air flow at normal temperature or the heated air flow passes through the first air inlet end 321 on the lower end surface of the moisture absorption rotary disc 320 to enter the first chamber 312, then passes through the first air outlet end 322 on the lower end surface of the moisture absorption rotary disc 320 again to flow out, and the other air flow passes through the second air inlet end 323 on the lower end surface of the moisture absorption rotary disc 320 to enter the second chamber 313, then passes through the second air outlet end 324 on the lower end surface of the moisture absorption rotary disc 320 again to flow out, so that the moisture in the air flow at normal temperature is better absorbed, the moisture absorbed by the desiccant rotor 320 is better regenerated and released into the heated air stream, thereby enabling continuous dehumidification of the indoor environment.
Optionally, the first air inlet end 321 and the first air outlet end 322 are both communicated with the outdoor environment, and the second air inlet end 323 and the second air outlet end 324 are both communicated with the indoor environment. Therefore, air in the outdoor environment can enter the first cavity 312 through the first air inlet end 321 and then flow out to the outdoor environment through the first air outlet end 322, air in the indoor environment can enter the second cavity 313 through the second air inlet end 323 and then flow out to the indoor environment through the second air outlet end 324, and internal circulation of the indoor air is formed.
Optionally, a first baffle 330 may be rotatably disposed within the recirculation chamber 311. Thus, since the first partition 330 is located in the circulation cavity 311 and divides the circulation cavity 311 into the first chamber 312 and the second chamber 313, the first partition 330 is rotatably disposed, the first chamber 312 and the second chamber 313 can be switched by the rotation of the first partition 330, and the communication relationship between the first air inlet 321, the first air outlet 322, the second air inlet 323 and the second air outlet 324 can be changed, so that the flow channel of the air flow is switched by the rotation of the first partition 330 according to the outdoor environment quality, the humidity conditioner 300 is in the state of external circulation or internal circulation, the indoor air flow and the outdoor air flow can be exchanged or not exchanged in the dehumidification process, the indoor air flow and the outdoor air flow can be exchanged under the condition of the indoor air exchange requirement, and the indoor air flow and the outdoor air flow can not be exchanged under the condition of the outdoor air quality without the poor air exchange requirement, the indoor dehumidification method has the advantages that outdoor dirty air is prevented from entering the indoor space, outdoor airflow is selectively utilized, dependence on outdoor environment is reduced, dehumidification stability is improved, and indoor air quality is maintained.
Optionally, heating portion 314 is disposed in both first chamber 312 and second chamber 313.

and S03, the controller determines a target pressure interval where the suction pressure is located from at least two preset pressure intervals, and controls the air conditioner and the humidity conditioner to operate according to the operation modes of the air conditioner and the humidity conditioner corresponding to the target pressure interval.
By adopting the dehumidification method provided by the embodiment of the disclosure, the indoor environment can be cooled and dehumidified by matching the air conditioner and the dehumidifier, because the dehumidification capacity of the air conditioner is related to the evaporation pressure of the evaporator of the air conditioner, the evaporation pressure of the evaporator is related to the temperature of the evaporator pipe, the dehumidification capacity of the air conditioner is stronger as the pipe temperature of the evaporator is lower, therefore, the pipe temperature of the evaporator is lower as the evaporation pressure is lower, the dehumidification capacity of the air conditioner is stronger, and when the air conditioner normally operates, the suction pressure and the evaporation pressure of the compressor are almost the same, the operation mode of the air conditioner and the dehumidifier can be more accurately reflected according to the suction pressure of the air conditioner compressor, so that the operation mode of the air conditioner and the dehumidifier can be more accurately matched according to the size relation between the suction pressure of the air conditioner and the target evaporation pressure, therefore, the wet load of the indoor environment is eliminated more efficiently, the comfort of the indoor environment is improved, and the energy consumption is reduced.
Optionally, the controller determines that the air conditioner is operated in a cooling mode, and obtains a suction pressure of a compressor of the air conditioner detected by the pressure sensor, and the method includes: the controller determines that the air conditioner operates in a cooling mode, and if a dehumidification instruction is obtained, the controller obtains the suction pressure of the air conditioner compressor detected by the pressure sensor. Therefore, after the controller acquires the dehumidification instruction, the suction pressure of the air conditioner compressor detected by the pressure sensor is acquired, the operation mode of the air conditioner and the dehumidifier is controlled according to the size relation between the suction pressure and the target evaporation pressure, the indoor environment can be dehumidified according to the requirements of users, and the user experience is improved.

Like this, the user can send the dehumidification instruction to the controller according to self demand, and the controller then acquires the suction pressure of the air conditioner compressor that pressure sensor detected after acquireing the dehumidification instruction, then controls the operation mode of air conditioner and damping machine according to suction pressure and target evaporating pressure's big or small relation, can dehumidify the indoor environment according to user's demand, has improved user's experience.
Optionally, the controller obtains voice information sent by the user through a voice input end, and analyzes the dehumidification instruction from the voice information. Therefore, the user can send voice information to the voice input end, the controller obtains the voice information sent by the user and analyzes the dehumidification instruction, and the operation modes of the air conditioner and the humidity conditioner are controlled more accurately.
Optionally, the controller obtains a dehumidification command issued by a user through a remote controller. Therefore, a user can send a dehumidification instruction to the controller through the remote controller, and the controller obtains the dehumidification instruction to more accurately control the operation modes of the air conditioner and the humidity conditioner.
Optionally, the controller obtains a target evaporating pressure, including: the controller acquires a set temperature and a set humidity, and determines a dew point temperature corresponding to the set temperature and the set humidity; and determining a target evaporation temperature according to the dew point temperature, and acquiring a target evaporation pressure according to the target evaporation temperature. Thus, by determining the dew point temperature when the temperature and humidity of the indoor environment are at the set temperature and the set humidity, then determining the target evaporation temperature of the air conditioner compressor according to the dew point temperature, and acquiring the target evaporation pressure of the air conditioner compressor at the target evaporation temperature, and because the preset pressure interval is acquired according to the target evaporation pressure, the operation modes of the air conditioner and the humidity regulator are controlled according to the acquired suction pressure of the air conditioner compressor at different preset pressure intervals, namely, the operation modes of the air conditioner and the humidity regulator are controlled according to the magnitude relation between the acquired suction pressure of the air conditioner compressor and the suction pressure of the air conditioner compressor when the temperature and humidity of the indoor environment are at the set temperature and the set humidity, the air conditioner and the humidity regulator can be more accurately matched, and the humidity load of the indoor environment can be more efficiently eliminated, improve the comfort of the indoor environment and reduce the energy consumption.
Optionally, the controller determining the target evaporation temperature from the dew point temperature comprises: the controller is according to the formula: t is1＝T2-T3To determine a target evaporation temperature, wherein T1Is the target evaporation temperature, T2Is the dew point temperature, T3Is set for a temperatureThe value is, for example, 2 ℃. Therefore, the target evaporation temperature determined by the controller according to the dew point temperature is always lower than the dew point temperature, namely the evaporation temperature of the evaporator of the air conditioner is always lower than the dew point temperature, and the air conditioner has better dehumidification capacity at the moment, so that the air conditioner is controlled to dehumidify under the condition that the suction pressure of the compressor of the air conditioner is lower than the evaporation pressure of the evaporator at the target evaporation temperature, and the indoor environment is cooled and dehumidified more efficiently.
In some examples, the controller may calculate the dew point temperature corresponding to the set temperature and the set humidity according to a calculation formula of the temperature and the dew point temperature in the prior art, and the evaporator of the air conditioner is required to have the dehumidification capability at the current dew point temperature, and the evaporation temperature of the evaporator is necessarily lower than the dew point temperature, so the controller calculates the dew point temperature according to the formula: t is1＝T2-T3The target evaporation temperature is determined, the determined target evaporation temperature is lower than the dew point temperature, namely the air conditioner evaporator under the target evaporation temperature has better dehumidification capacity, the target evaporation pressure of the air conditioner evaporator under the target evaporation temperature can be detected through the pressure gauge, at least two preset pressure intervals are obtained according to the target evaporation pressure, after a dehumidification instruction is obtained, the operation modes of the air conditioner and the dehumidifier are controlled according to the condition that the suction pressure of an air conditioner compressor is in different preset pressure intervals, and the indoor environment is cooled and dehumidified more efficiently and more efficiently.
Alternatively, if the preset pressure interval is two preset pressure intervals: a first preset pressure interval and a second preset pressure interval; the air conditioner and the dehumidifier respectively correspond to the operation modes in different preset pressure intervals, and the operation modes comprise: the operation mode of the air conditioner and the humidity regulator in the first preset pressure interval is as follows: the air conditioner performs dehumidification together with the humidity regulator while refrigerating; the operation mode of the air conditioner and the humidity regulator in the second preset pressure interval is as follows: the dehumidifier dehumidifies and the air conditioner refrigerates. Like this, the suction pressure of the air conditioner compressor that makes the controller acquire if under first preset pressure interval, then control the air conditioner in refrigerated, dehumidify with the damping machine jointly, if under second preset pressure interval, then control the air conditioner and refrigerate, the damping machine dehumidifies, thereby select better energy-conserving comfortable cooling dehumidification mode according to the change of the suction pressure of air conditioner compressor, better control air conditioner and damping machine, the stability of indoor environment cooling dehumidification has been improved.
Optionally, the first preset pressure interval and the second preset pressure interval are defined by the target evaporation pressure, that is, the first preset pressure interval is an interval smaller than or equal to the target evaporation pressure, and the second preset pressure interval is an interval larger than the target evaporation pressure. Therefore, the controller acquires a first preset pressure interval and a second preset pressure interval defined according to the target evaporation pressure, and can judge the size relation between the suction pressure of the air conditioner compressor and the target evaporation pressure under different preset pressure intervals according to the acquired suction pressure of the air conditioner compressor, so that the air conditioner and the humidity regulator can be better controlled.
In some examples, if the suction pressure of the air conditioner compressor obtained by the controller is in a first preset pressure interval, the suction pressure of the air conditioner compressor at this time is less than or equal to the target evaporation pressure, since the suction pressure of the compressor is substantially the same as the evaporating pressure during the normal operation of the air conditioner, when the suction pressure of the compressor is less than or equal to the target evaporating pressure, the evaporation pressure corresponding to the suction pressure of the current compressor is also less than or equal to the target evaporation pressure, the evaporation temperature of the evaporator of the air conditioner is lower than the dew point temperature corresponding to the set temperature and the set humidity, the air conditioner has better refrigerating and dehumidifying capacity, therefore, the controller controls the air conditioner to dehumidify together with the humidity regulator while refrigerating, the air conditioner is used for cooling and dehumidifying, the humidity regulator is used for assisting in dehumidifying, and the indoor environment can be cooled and dehumidified more efficiently; if the suction pressure of the air conditioner compressor acquired by the controller is within the second preset pressure interval, the suction pressure of the air conditioner compressor at the moment is greater than the target evaporation pressure, namely the evaporation pressure corresponding to the suction pressure of the current compressor is greater than the target evaporation pressure, the evaporation temperature of the air conditioner evaporator is higher than the dew point temperature corresponding to the set temperature and the set humidity at the moment, and the air conditioner cannot dehumidify when being cooled, so that the controller controls the humidity regulator to intervene to dehumidify, the air conditioner refrigerates, and the temperature fluctuation of the indoor environment can be reduced while the humidity load of the indoor environment can be efficiently removed.
Optionally, in a second preset pressure interval, the dehumidifier performs dehumidification, including: the controller controls the moisture absorption turntable of the humidity regulator to operate at the highest rotating speed; the controller controls the fan of the humidity conditioner to operate at the highest rotation speed under the condition of meeting the minimum regeneration temperature. Therefore, under the second preset pressure interval, the suction pressure of the air conditioner compressor is greater than the target evaporation pressure, namely, the air conditioner has poor dehumidification capacity during refrigeration and cooling, so that the dehumidifier needs to be controlled to dehumidify, at the moment, the controller controls the moisture absorption rotary disc of the dehumidifier to operate at the highest rotating speed so as to improve the dehumidification efficiency, but the fan of the dehumidifier is controlled to operate at the highest rotating speed under the condition of meeting the minimum regeneration temperature of the dehumidifier so as to further improve the dehumidification efficiency of the indoor environment.
It can be understood that, because the moisture in the air flow can be absorbed by the moisture absorption rotary table when the air flow at normal temperature flows through the moisture absorption rotary table, and the heated air flow can regenerate the moisture absorbed in the moisture absorption rotary table to release the moisture into the air flow when the air flow flows through the moisture absorption rotary table for absorbing moisture, by using the characteristic of the moisture absorption rotary table, it can be obtained through experiments that the minimum temperature capable of regenerating the moisture absorbed in the moisture absorption rotary table is the minimum regeneration temperature when the heated air flow flows through the moisture absorption rotary table for absorbing moisture.
Optionally, controlling the fan of the humidity conditioner to operate at the highest rotation speed under the condition that the minimum regeneration temperature is met comprises: the controller controls the heating part of the dehumidifier to operate at the highest heating power and simultaneously gradually increases the rotating speed of the fan of the dehumidifier; and acquiring the temperature of the air flow flowing through the heating part, controlling the rotating speed of a fan of the humidity conditioner to stop rising and operating at the current rotating speed under the condition that the temperature of the air flow is the same as the minimum regeneration temperature. Therefore, in the process that the rotating speed of the fan of the humidity conditioner is increased, the flow velocity of the air flow is accelerated, and the heating efficiency of the heating part to the air flow is reduced, so that the rotating speed of the fan of the humidity conditioner is gradually increased while the heating part of the humidity conditioner is controlled to operate at the highest heating power through the controller, then the temperature of the air flow flowing through the heating part is obtained, under the condition that the temperature of the air flow is the same as the minimum regeneration temperature, the fan of the humidity conditioner is controlled to operate at the current rotating speed, the humidity conditioner can be enabled to operate at the highest rotating speed, namely, the maximum air volume under the condition that the minimum regeneration temperature is met, and the dehumidification efficiency of the indoor environment is further improved.
In some examples, the maximum power of the dehumidifier is 200w/h, the minimum regeneration temperature is 50 ℃, the heating part of the dehumidifier operates at 200w/h, the air flow flowing through is heated, the rotating speed of a fan of the humidity regulator is gradually increased, the flow rate of the air flow flowing through the heating part is gradually increased, the heat exchange efficiency between the air flow and the heating part is reduced when the flow rate of the air flow is increased, i.e., the heating efficiency of the heating part, thereby causing the temperature of the air flow passing through the heating part to decrease, the controller acquires the temperature of the air flow passing through the heating part through the temperature sensor, when the temperature of the air flow passing through the heating part is 50 ℃, the rotating speed of the fan of the humidity regulator is 400r/min, the rotating speed of the fan of the humidity regulator is controlled to stop rising and to run at the current rotating speed of 300r/min, therefore, the humidity regulator can meet the minimum regeneration temperature and improve the air quantity, thereby improving the dehumidification capacity.
Optionally, in the first preset pressure interval and the second preset pressure interval, the initial states of the dehumidifier during dehumidification are both internal circulation states. Therefore, when the temperature and the humidity of the indoor environment are regulated through the air conditioner and the humidity regulator, the quality of the outdoor environment is not clear, and the humidity regulator is controlled to be in an internal circulation state in order to prevent low-quality air in the outdoor environment from entering the indoor environment.
It is understood that the initial state of the humidifier is a state immediately after the humidifier is turned on.
Optionally, the method for dehumidifying further comprises: and S04, the controller acquires the air quality of the outdoor environment, and controls the humidity conditioner to work in an external circulation state if the air quality of the outdoor environment is higher than that of the indoor environment. Like this, at the in-process that cools down the dehumidification to the indoor environment, the controller can also acquire the air quality of outdoor environment and indoor environment, according to the operating condition of the air quality control damping machine of outdoor environment, if the air quality of outdoor environment is higher than the air quality of indoor environment, then control damping machine is in the work of extrinsic cycle state, make the high quality air in the outdoor environment can get into indoorly, indoor low quality air can flow out to the open air, improve the air quality of indoor environment, further improve the comfort level of indoor environment temperature humidity control.
Alternatively, if the air quality of the outdoor environment is higher than that of the indoor environment, the controller controls the humidity conditioner to operate in an external circulation state, including: the controller controls the first diaphragm to rotate from the first position to the second position. Like this, rotate the second position from the first position through the first baffle of controller control, make first cavity intercommunication outdoor environment and indoor environment, second cavity intercommunication indoor environment and outdoor environment, first cavity and first air inlet end promptly, second air-out end intercommunication, second cavity and second air inlet end, first air-out end intercommunication, make the damping machine be in the extrinsic cycle state, outdoor high quality air can get into indoorly through first cavity, indoor low quality air can flow out to indoorly through the second cavity, when cooling down the dehumidification to indoor environment, improve indoor environment's air quality.
Optionally, the controller obtains the air quality of the outdoor environment and the air quality of the indoor environment detected by the air quality sensor, and further includes: if the air quality of the outdoor environment is lower than that of the indoor environment, the controller controls the humidity conditioner to work in an internal circulation state. Therefore, if the outdoor air quality is lower than the indoor air quality, the air quality of the outdoor environment is poor, and therefore the humidity regulator is controlled to work in an internal circulation state, outdoor dirty air is prevented from entering the indoor environment, and the indoor air quality is maintained.
Alternatively, if the air quality of the outdoor environment is lower than the air quality of the indoor environment, the controller controls the humidity conditioner to operate in an inner circulation state, including: the controller controls the first partition to rotate from the second position to the first position. Like this, rotate first position from the second position through the first baffle of controller control, make first cavity intercommunication outdoor environment, second cavity intercommunication indoor environment, first cavity and first air inlet end promptly, first air-out end intercommunication, second cavity and second air inlet end, second air-out end intercommunication, make the damping machine be in the inner loop state, outdoor low-quality air can drive the moisture in the moisture absorption carousel through first cavity circulation flow, indoor high-quality air can absorb the moisture in the air current through second cavity circulation flow, when cooling the dehumidification to indoor environment, avoid outdoor dirty air to enter into indoorly, keep the quality of indoor air.
Optionally, the air quality comprises: the content of PM2.5 in air and/or the content of carbon dioxide in air. Therefore, the air quality of the indoor environment and the air quality of the outdoor environment can be judged according to the PM2.5 content and/or the carbon dioxide content in the air of the indoor environment and the air of the outdoor environment, the external circulation or the internal circulation state of the humidity conditioner can be better controlled, and the quality of the indoor environment is improved.
It is understood that the air quality of the outdoor environment is higher than the air quality of the indoor environment, meaning that the amount of PM2.5 and/or carbon dioxide in the outdoor environment air is less than the amount of PM2.5 and/or carbon dioxide in the indoor environment air, and the air quality of the outdoor environment is lower than the air quality of the indoor environment, meaning that the amount of PM2.5 and/or carbon dioxide in the outdoor environment air is greater than or equal to the amount of PM2.5 and/or carbon dioxide in the indoor environment air.
