Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For example: in patent document CN201210111997.9, the original set temperature is compensated and set according to the detected signal, so as to control the operating frequency of the compressor and the wind speed gear of the indoor unit, and indirectly compensate the humidity of the air conditioner; but changing the compressor frequency can have an effect on temperature control.
For example: in patent document CN201710096326.2, the controller controls the angle of the spray header to change the spray area, so as to spray different areas, increase the area where air and water contact, and control the amount of humidification; but the air humidification is not uniform.
For example: in patent document CN201611089117.7, the amount of humidification is changed by the magnitude of the wind speed by detecting the humidity of the outdoor environment and calculating the difference between the humidity of the indoor environment and the humidity of the outdoor environment; but changing wind speed affects comfort.
According to an embodiment of the present invention, there is provided a humidification control device. Referring to fig. 1, a schematic diagram of an embodiment of the apparatus of the present invention is shown. The humidification control device may include: a controller and a heat exchanger 6. The method can also comprise the following steps: a water supply system and/or a water drainage system. The water supply system and/or the water drainage system are arranged on the periphery of the heat exchanger 6. The water supply system may include: a water supply system and a water replenishing system.
Wherein the controller can be used for controlling in at least one of the following control situations.
The first control scenario: the controller may be configured to determine a humidification water consumption amount required by the air conditioning system according to a target moisture content required by a user in an environment to which the air conditioning system to be controlled belongs, and control the water supply system to supply water and humidify the water by using water (such as tap water, water in a water storage tank, and condensed water of the air conditioning system) in a water pan 1 of the air conditioning system according to the humidification water consumption amount. The feed water is humidified, preferably isothermally humidified. Specifically, the water supply system is arranged on the first side above the heat exchanger 6, and can be used for performing water supply humidification on the environment to which the air conditioning system to be controlled belongs by using tap water or water in the water storage tank under the control of the controller, so as to realize isothermal humidification treatment on the environment.
In an alternative example, the determining, by the controller, the amount of humidification water required by the air conditioning system according to the target moisture content required by the user in the environment to which the air conditioning system to be controlled belongs may include:
the controller may be further specifically configured to determine whether a difference between a target moisture content (e.g., moisture content d2) required by a user in an environment to which the air conditioning system to be controlled belongs and a return air moisture content (e.g., moisture content d1) of a return air inlet of the air conditioning system accounts for a current ratio of the return air moisture content to be greater than a set ratio.
Alternatively, the controller may determine whether the difference between the target moisture content (e.g. moisture content d2) required by the user in the environment where the air conditioning system to be controlled belongs and the return air mouth moisture content (e.g. moisture content d1) of the return air inlet of the air conditioning system accounts for the current ratio of the return air mouth moisture content to be greater than a set ratio, and may include:
the controller may be further configured to obtain a return air inlet temperature (e.g., the return air inlet temperature t1) and a return air inlet relative humidity (e.g., the return air inlet relative humidity Φ 1) of the return air inlet of the air conditioning system, and obtain a target temperature (e.g., the target temperature t2) and a target relative humidity (e.g., the target relative humidity Φ 2) set by a user in the air conditioning system.
More optionally, the obtaining, by the controller, a return air inlet temperature (e.g., the return air inlet temperature t1) and a return air inlet relative humidity (e.g., the return air inlet relative humidity Φ 1) of the return air inlet of the air conditioning system may include: the controller may be further configured to obtain a return air inlet temperature (e.g., the return air inlet temperature t1) of the return air inlet of the air conditioning system detected by the first temperature sensor disposed in the return air channel or the return air inlet of the air conditioning system, and obtain a return air inlet relative humidity (e.g., the return air inlet relative humidity Φ 1) of the return air inlet of the air conditioning system detected by the first humidity sensor disposed in the return air channel or the return air inlet of the air conditioning system.
From this, detect through the temperature and humidity sensor who sets up at return air passageway or return air inlet and obtain return air inlet temperature and return air inlet relative humidity for the precision that acquires is good, the reliability is high to return air inlet temperature and return air inlet relative humidity.
More optionally, the obtaining, by the controller, a target temperature (e.g., the target temperature t2) and a target relative humidity (e.g., the target relative humidity Φ 2) set by a user in the air conditioning system may include: the controller may be further configured to obtain a target temperature (e.g., target temperature t2) and a target relative humidity (e.g., target relative humidity Φ 2) set by a user, where the target temperature and the target relative humidity are sent by any one of a remote controller, a hand operator, a key, a client APP, and a voice module of the air conditioning system.
For example: in the temperature control system, a user can set a required temperature through a manual operator or a remote controller, set data are transmitted to a main chip, a refrigeration (heating) system is controlled through a controller, indoor air is sent to the heat exchanger 6 to exchange heat, the indoor air reaches an air supply required value t2 after being processed, and the indoor air is mixed with the indoor air to reach a set temperature required value t 1.
Therefore, the target temperature and the target relative humidity set by the user are acquired through various modes, the acquisition mode is flexible and convenient, and convenience and reliability in use of the user are improved.
The controller may be further configured to determine the moisture content of the return air mouth according to the temperature of the return air inlet and the relative humidity of the return air inlet, and determine the target moisture content according to the target temperature and the target relative humidity.
The controller may be further configured to determine a current ratio of a difference between the target moisture content and the return air moisture content to the return air moisture content, and determine whether the current ratio is greater than a set ratio.
For example: judging whether humidification is performed or not by judging the difference value percentage n between the indoor moisture content and the set moisture content; the humidification water amount is accurately judged through the moisture content needing to be increased of a user, the air supply speed v of an air conditioning system, the current vaporization latent heat value r of water at the air supply temperature and the like.
Therefore, the return air containing moisture content is determined according to the return air inlet temperature and the return air inlet relative humidity of the air conditioning system, the target moisture content is determined according to the target temperature and the target relative humidity set by a user, the current proportion is determined according to the return air containing moisture content and the target moisture content, and whether the current proportion is larger than the set proportion or not is judged, so that the corresponding moisture content is determined more accurately and reliably, and the accuracy and the reliability of judgment of the starting time of the isothermal humidification processing are improved.
Wherein, the setting the proportion may include: one set ratio of the set ratio range, or one set ratio of the set plurality of ratio steps.
For example: as shown in Table 1, a plurality of gears suitable for human body humidity, such as 40%, 50% and 60%, are set on a hand operator or a remote controller for selection by a user.
Table 1: statistical table for relative humidity design standard of partial building
From this, through the proportion of setting for of multiple scope or multiple gear, can satisfy different user's different humidification demands, also can satisfy the humidification demand of same user under different environment, application scope is wider, and the commonality is stronger, and the convenience that the user used is experienced and the travelling comfort is experienced better.
And the controller can be specifically used for determining the humidification water consumption required to be supplied by the water supply system at present and controlling the water supply system to supply water for humidification according to the humidification water consumption if the current proportion is larger than the set proportion.
For example: when the system operates, the corresponding moisture content d1 is obtained according to the return air temperature t1 and the return air relative humidity value phi 1, the moisture content d2 is obtained according to the return air temperature t1 and the relative humidity value phi 2 expected by a user, and partial data are shown in table 2; the moisture content calculation method can also be programmed into the main chip: d is 0.622Pq/Pg, wherein Pq and Pg are respectively the dry air and water vapor pressure. And calculating the difference between the return air moisture content (such as d2) and the moisture content set by a user (such as d1), setting a fixed percentage n, namely (d2-d1)/d1, and controlling the air conditioner to perform isothermal humidification treatment when the percentage value n1 is greater than or equal to the set value n in actual operation.
In a specific use process, if the current proportion is smaller than or equal to the set proportion, the water supply system is controlled to stop water supply and/or carry out dehumidification treatment.
For example: when the percentage n1 is smaller than the set value n during actual operation, the controller controls the electric adjusting water pump 4 to be closed, and the air conditioner controls the air conditioner to perform dehumidification treatment during refrigeration or dehumidification.
Therefore, under the condition that the difference value of the target moisture content required by a user and the return air mouth moisture content of the return air inlet of the air conditioning system accounts for the current proportion of the return air mouth moisture content to be larger than the set proportion, the humidification water consumption required by the water supply system is determined, the water supply system is controlled to supply water for humidification according to the humidification water consumption, the isothermal humidification treatment of the air conditioning system is realized, the humidification water consumption required by the air conditioning system is more accurately determined, and the method is simpler, more convenient and more reliable.
Alternatively, the controller determining the amount of humidification water currently required to be supplied by the watering system may comprise:
the controller may be further configured to determine a target moisture demand (e.g., a user moisture demand Q) required by a user according to a target wind speed and a moisture content value set by the user in the air conditioning system, and determine a current latent heat value for vaporization of water according to a current air supply temperature (e.g., an air supply temperature t3) of an air supply outlet of the air conditioning system.
More optionally, the determining, by the controller, a target moisture content required by the user (for example, a user moisture content Q) according to the target wind speed and the moisture content value set by the user in the air conditioning system may include:
the controller may be further configured to obtain a target wind speed (e.g., a user-set wind speed v) set by a user and sent by any one of a remote controller, a manual operator, a key, a client APP, and a voice module of the air conditioning system.
The controller may be further specifically configured to determine a target air volume (e.g., air volume G) of the air conditioning system according to the target air speed and the moisture content value.
The controller may be further configured to use a predetermined coefficient times a product of the target supply air volume and the difference (i.e., a difference between a target moisture content d2 required by the user in an environment to which the air conditioning system belongs and a return air inlet moisture content d1 of the return air inlet of the air conditioning system) as a target moisture content required by the user (e.g., a user moisture content Q).
For example: acquiring the air supply volume G according to the set air speed v of the user, wherein the moisture content of the user is 1000G (d2-d 1); according to the air supply temperature t3 known by the air supply outlet temperature sensor, the current vaporization latent heat value r of the water at the temperature t3 can be obtained, and the water addition amount W is equal to Q/r, namely W is equal to 1000G (d2-d 1)/r.
Therefore, the target wind speed set by the user is acquired in various ways, and the acquisition way is flexible and convenient; and then the target air supply volume of the air conditioning system is determined according to the target air speed, and the target air supply volume and the preset coefficient times of the difference value between the target moisture content and the return air mouth moisture content are used as the target moisture content required by the user.
More optionally, the controller may include, according to a current supply air temperature of the air supply outlet of the air conditioning system (e.g., supply air temperature t3), a current latent heat value of vaporization of water:
the controller may be further configured to obtain a current air supply temperature and a current atmospheric pressure (e.g., air supply temperature t3) of the air supply outlet of the air conditioning system, which are detected by a second temperature sensor disposed in the air supply passage or the air supply outlet of the air conditioning system. For example: the latent heat of vaporization is related to the supply air temperature and the current atmospheric pressure, as shown in table 2.
The controller may be further configured to, according to a correspondence between a set air supply temperature and a set atmospheric pressure and a set latent heat value for vaporization, use, as the current latent heat value for vaporization, the set latent heat value for vaporization that is the same as the current air supply temperature and the current atmospheric pressure in the correspondence.
For example: arranging a temperature sensor in the air supply channel, and detecting the air supply temperature t 3; a temperature sensor and a relative humidity sensor are arranged in the return air channel, and the return air temperature t1 and the return air relative humidity phi 1 are detected; the temperature t2, the relative humidity value phi 2 and the air supply speed v which are expected by a user are obtained through a remote controller or a hand operator.
From this, through the current air supply temperature that detects air conditioning system's supply-air outlet, and then confirm the current latent heat value of vaporization of this current supply-air temperature offal water, be favorable to confirming the current required humidification water consumption according to the current latent heat value of vaporization of supply-air temperature offal water, and then realize isothermal humidification and handle, precision and reliability can all obtain guaranteeing to promote user's comfort and experience fabulously.
The controller may be further configured to use a ratio of the target moisture content to the vaporization latent heat value as a humidification water consumption amount currently required to be supplied by the water supply system, that is, a current water supply amount currently required to be supplied by the water supply system.
Therefore, the target moisture demand of the user is determined according to the target air speed set by the user, and the ratio of the target moisture demand to the vaporization latent heat value of water at the current air supply temperature of the air supply outlet of the air conditioning system is used as the humidification water consumption required by the water supply system, so that the humidification water consumption required by the water supply system is determined more simply and accurately, and the accuracy and the reliability of isothermal humidification treatment are guaranteed.
Optionally, the controller controls the water supply system to humidify the supplied water according to the amount of the humidification water, and may include:
the controller may be further configured to control a water supply flow rate and/or a water supply rate of the water supply system according to the humidification water consumption, so as to supply water in the water pan 1 to the nozzles 5 disposed above the heat exchanger 6.
More optionally, the controller controlling the feedwater flow and/or the feedwater rate of the feedwater system may include:
the controller can be specifically used for controlling the current rotating speed of a water pump 4 arranged on a water supply pipe 2 between the water receiving tray 1 and a water distribution pipe 3 positioned above the heat exchanger 6.
The water supply pipe 2, the water pump 4, the water distribution pipe 3 and the nozzle 5 form the water supply system. In the water supply system, the water pump 4 may include: an electric regulating water pump. And/or, the nozzle 5 may include: spray amount adjustable nozzle. And/or the number of the nozzles 5 is more than one, and the more than one nozzles 5 are uniformly or non-uniformly arranged on the water distribution pipe 3 at intervals.
For example: the water receiving tray 1 is arranged at the bottommost position of the system, the tail end of the water supply pipe 2 is connected with the water receiving tray 1 and keeps a certain distance, the other end of the water supply pipe 2 is connected with the water distribution pipe 3 through a bent pipe, a water supply pipeline formed by the water supply pipe 2 and the water distribution pipe 3 is arranged in front of the heat exchanger 6, the arrangement height of the water distribution pipe 3 is slightly higher than that of the heat exchanger 6, and air flowing through the heat exchanger 6 can completely perform moisture content exchange with spray water; and the water supply pipes 2 can be flexibly arranged at any positions such as the left side, the right side or the middle of the water distribution pipe 3 according to the requirements, and are particularly shown in figure 2. The electric adjusting water pump 4 is arranged on the water distribution pipe 3, and the nozzles 5 are uniformly distributed on the water distribution pipe 3. An air supply temperature sensor and an air return humidity sensor are arranged between the heat exchanger 6 and the water supply pipeline, and an air return temperature sensor and an air return humidity sensor are arranged at an air return inlet.
Therefore, the control of the water supply flow, the water supply flow rate or the water supply speed and the like from the water supply pipe to the water distribution pipe and then to the nozzle is realized by controlling the current rotating speed of the water pump on the water supply pipe in the water supply system, the water supply quantity can be flexibly and accurately controlled, and the improvement of the accuracy and the reliability of humidification control is facilitated.
And the controller can be specifically used for controlling the spraying amount of a nozzle 5 arranged above the heat exchanger 6 in the air conditioning system, so that the water supplied by the water supply system is uniformly or unevenly sprayed onto the air (such as low-temperature or high-temperature air) with the set temperature after heat exchange treatment of the heat exchanger 6 through the nozzle 5, and the water mist sprayed by the nozzle 5 reaches the target moisture content and the target air supply temperature set by a user and then is sent into the environment.
For example: according to theoretical calculation, the humidity required by a user can be achieved after the air sent into the room is humidified, but the temperature is slightly reduced, so that the temperature and the humidity can be described as being sent into the environment after reaching the precision range.
From this, through the feedwater flow, the feedwater rate etc. of controlling water supply system according to the humidification water consumption of confirming, supply the water in the water collector to the nozzle department of heat exchanger top, and then the volume of spraying of control nozzle sprays water evenly or unevenly on the air of the settlement temperature after the heat exchanger heat transfer is handled, the water smoke that makes the nozzle spray is sent into the environment that the user is located after the isothermal treatment of settlement temperature air after the heat exchanger is handled again, realize accurate and reliable isothermal humidification processing, promote user's travelling comfort greatly and experience, it is fabulous.
The second control scenario: the controller can also be used for controlling the water supplementing system to supplement water to the water receiving tray 1 by using external tap water or water in the water storage tank or controlling the drainage system to drain water in the water receiving tray 1 according to the actual water level height of the water receiving tray 1 of the air conditioning system. Specifically, the water replenishing system is arranged on the second side above the heat exchanger 6, and can be used for replenishing water by using the condensed water of the air conditioner. The drainage system is arranged below the heat exchanger 6, specifically can be positioned below the water replenishing system, and can be used for draining water in the water pan 1 of the air conditioning system.
For example: the water supply system and the drainage system can accurately judge the amount of water required for humidification of the air conditioning system according to the requirements of users, can humidify by using condensed water in summer and simultaneously realize an automatic water supplement control system, so that the comfort level of the users when using the air conditioners is improved; meanwhile, the control method of the drainage system in the air conditioning system can ensure the safe operation of the air conditioning system. Therefore, automatic water replenishing and draining of the air conditioning system are realized through system control, the problem that the temperature and the humidity of the indoor air environment cannot be independently controlled is solved, and the problem that the indoor relative humidity cannot be quantitatively controlled in the traditional humidification mode is also solved; moreover, aiming at the low indoor cold quantity requirement in the northern transition season, the humidification system can be used for taking away latent heat of vaporization in air to achieve the purposes of humidification and cooling, the problem of indoor air drying caused by the use of air conditioning equipment in winter and summer is solved, and the energy consumption of the air conditioner is reduced.
For example: a water replenishing system, a water supply system and a water drainage system; the amount of humidification water required by the air conditioning system can be accurately judged according to the requirements of users; by reasonably utilizing the summer condensed water for humidification, the automatic switching of the condensed water and a municipal water replenishing control system is realized; the safe operation of the air conditioning system can be ensured.
From this, through optional cooperation setting of water supply system, water charging system, drainage system etc. and heat exchanger, under the control of controller, can realize carrying out the humidification according to user's demand moisture under the condition that does not influence air conditioning system's air supply temperature, not only promote the humidification precision, still promoted user's comfort and experienced.
In an optional example, the controlling, by the controller, the water replenishing system to replenish the water receiving tray 1 with externally-connected tap water or water in a water storage tank according to an actual water level height of the water receiving tray 1 of the air conditioning system may include:
the controller can be specifically used for acquiring the actual water level height of the water pan 1 of the air conditioning system.
Optionally, the obtaining, by the controller, the actual water level height of the water pan 1 of the air conditioning system may include: the controller may be further configured to obtain the actual water level detected by a water level switch 11 disposed in the water pan 1 of the air conditioning system. The water pan 1 is arranged below the heat exchanger 6.
From this, through the actual water level height that obtains of acquireing water collector well water level switch detection for to the acquireing of actual water level height in the water collector accurate, reliable, be favorable to in time carrying out in time and accurately humidification control based on actual water level height in the water collector, be favorable to promoting the convenience and the reliability of humidification control.
The controller may be further configured to determine whether the actual water level is less than or equal to a set minimum water level (e.g., the minimum water level h of the water level switch 11).
The controller may be further configured to control the water charging system to be turned off if the actual water level is greater than the minimum water charging height, and control the water supply system to supply water and humidify only by using the condensed water of the air conditioning system in the water receiving tray 1.
For example: according to the moisture content required by the detection air conditioning system of the humidity control system part, the controller controls the electric adjusting water pump 4 to supplement water by using condensed water, and the condensed water is sent into the water distribution pipe 3 through the water supply pipeline 2 and distributed by the nozzle to perform moisture content exchange with air. When the control system detects that the amount of condensed water exceeds the designed height, the excess water is discharged by the overflow pipe 9, and the continuous water discharge is stopped until the excess water reaches the set height h of the water level switch. If the condensed water quantity is not enough to reach the water quantity required by the user, namely, the water replenishing height does not reach the set height h of the water level switch, the controller controls the power-off normally closed switch 8 to be powered on for replenishing water, and when the set height h is reached, the power-off normally closed switch 8 is closed to stop replenishing water.
The mode of humidifying the feedwater may include: and (5) isothermal humidification.
Therefore, the humidification treatment can be carried out under the condition of not influencing the air supply temperature through the isothermal humidification treatment, and the comfort of the user is greatly improved.
Or, the controller may be further specifically configured to control the water charging system to be turned on if the actual water level is less than or equal to the minimum water charging height, and control the water charging system to perform water charging and humidifying by using the condensed water of the air conditioning system in the water receiving tray 1 and tap water or water in a water storage tank supplied by the water charging system.
For example: moisturizing, among the drainage control system, set for water level switch height h and be minimum moisturizing height, detect 1 water level height h1 of water collector, and give main control chip with the signal transmission, main control chip controls outage normally closed switch 8 through the controller and switches on and off, when water level switch detects that water level height h1 is not more than h unsatisfied when setting for the requirement, controller control outage normally closed switch 8 circular telegram is opened, moisturizing pipe 7 carries out the moisturizing, when water level switch detects 1 water level height h1 of water collector and satisfies when setting for the demand, controller control outage normally closed switch 8 circular telegram is closed, moisturizing pipe 7 stops the moisturizing. Through rational utilization comdenstion water humidification simultaneously can with municipal water supply automatic switch-over, when practicing thrift the humidification water, can ensure that the moisturizing volume in time supplies.
Therefore, the water supply system is controlled to only utilize the condensed water of the air conditioning system in the water receiving tray to supply water and humidify under the condition that the actual water level height in the water receiving tray is greater than the set minimum water level height, and the water is supplemented and humidified under the condition that the actual water level height is less than or equal to the minimum water level height, so that the reliability of humidification treatment can be ensured, and the convenience and the comfort of a user are ensured.
Optionally, the controller controls the water replenishing system to be turned on, and may include: the controller may be further configured to control a first control switch 8 that may be configured to control the water replenishing system to be turned on. The first control switch 8 may include: and (4) closing the valve normally when the power is cut off.
Wherein, the moisturizing system can include: and the water replenishing pipe 7 is positioned above the drainage system and communicated to the side wall of the water receiving tray 1. The first control switch 8 is arranged on the water replenishing pipe 7.
For example: moisturizing is sent into humidification system through moisturizing pipe 7 for the humidification, and the moisturizing pipe 7 other end is connected with municipal water supply line, also can be connected with the storage water tank, and 7 mounting heights of moisturizing pipe should be higher than 9 knecks of overflow pipe. The power-off normally closed switch 8 is arranged on the water replenishing pipe 7.
Therefore, the water replenishing system is controlled to be opened or closed through the first control switch arranged on the water replenishing pipe, the structure is simple, and the control mode is simple, convenient and reliable.
In an alternative example, the controlling the drainage system to drain the water in the water pan 1 according to the actual water level height of the water pan 1 of the air conditioning system may include:
the controller may be further configured to determine whether the actual water level is greater than a set maximum water level (e.g., a set maximum water level h2 of the overflow pipe 9 in the drainage system) when the water replenishment system is turned on.
The controller may be further configured to control the drainage system to be opened if the actual water level is greater than the maximum water level, so as to drain water from the water receiving tray 1, where the actual water level is greater than the maximum water level.
For example: give main control chip with air conditioning system on-off state signal transmission, main control chip controls the drainage through the controller and is responsible for section outage normally closed switch 8 break-make electricity, and when air conditioning system was in the open mode, controller control outage normally open switch 9 circular telegram was closed, and when air conditioning system was in the closed mode, controller control outage normally open switch 13 circular telegram was opened, and then the moisturizing in the water collector 1 was responsible for through the drainage lateral conduit inflow drainage. When the water level switch has a fault, the water level height cannot be controlled, the water amount supplemented by the water supplementing pipe 7 exceeds the height h2 of the overflow pipe 9 with the set height, and the exceeded water amount flows into the main drainage pipeline 13 through the overflow pipe 9 so as to ensure the normal operation of the air conditioning system.
Optionally, the controller controls the drainage system to be opened, and may include: the controller may be further configured to turn on a second control switch 11 that may be configured to control the drainage system. The second control switch 11 may include: and a normally open valve is opened when power is cut off.
Therefore, the second control switch arranged in the drainage system controls the drainage system to be turned on or off, and the operation mode is simple, convenient and reliable.
Optionally, the draining, by the controller, the amount of water in the drip tray 1, in which the actual water level height is greater than the maximum water level height, may include: the controller can be further specifically used for discharging water quantity, in the water pan 1, of which the actual water level height is greater than the highest water level height to a main water discharge pipe 13 communicated with the overflow pipe 9 and the water discharge pipe branch pipe 12 respectively through an overflow pipe 9 arranged on the side wall of the water pan 1, and/or a through hole arranged at the bottom of the water pan 1 and the water discharge pipe branch pipe 12 communicated with the through hole.
Wherein the overflow pipe 9, the drain branch pipes 12 and the main drain pipe 13 form the drainage system. In the drainage system, may further include: a water level switch 10 arranged in the water pan 1 and a second control switch 11 arranged on the drainage pipeline branch pipe 12.
For example: a drainage system may include: overflow pipe 9, water level switch 10, power-off normally-open switch 11, drainage branch pipe 12 and drainage pipe 13. The installation height of the overflow pipe 9 is judged according to the surface area of the water receiving tray 1 and the maximum humidification quantity of the system. A through hole is opened at the bottom end of the water pan 1 and is connected with a drainage pipeline branch pipe 12, a power-off normally-open valve 11 passes through the drainage pipeline branch pipe 12, and the tail end 12 of the drainage branch pipe and the overflow pipe 9 finally converge into a main drainage pipe 13. A water level switch 10 is arranged on the drip tray 1 to control the height of the water level.
From this, carry out anti-overflow and drainage through the overflow pipe that sets up at the water collector lateral wall and the distribution pipe branch pipe that sets up in the water collector bottom and handle, the efficiency and the reliability of drainage can all obtain guaranteeing, and then can guarantee the reliability and the security of air conditioning system operation more reliably, and user experience is better.
Or, the controller may be further specifically configured to, if the actual water level is less than or equal to the maximum water level, continuously determine whether the actual water level is less than or equal to a set minimum water level (e.g., a minimum water level h of the water level switch 11), so as to control the water replenishing system to replenish the water receiving tray 1 with external tap water or water in the water storage tank when the actual water level is less than or equal to the minimum water level.
From this, through carry out timely drainage processing under the circumstances that actual water level height is greater than the highest water level height of settlement in the water collector, avoid actual water level height too high and take place to leak in the water collector, can promote the convenience that the user used, also can guarantee the reliability and the security of air conditioning system operation.

For example: in the temperature control system, a user can set a required temperature through a manual operator or a remote controller, set data are transmitted to a main chip, a refrigeration (heating) system is controlled through a controller, indoor air is sent to the heat exchanger 6 to exchange heat, the indoor air reaches an air supply required value t2 after being processed, and the indoor air is mixed with the indoor air to reach a set temperature required value t 1.

And calculating the difference between the return air moisture content (such as d2) and the moisture content set by a user (such as d1), setting a fixed percentage n, namely (d2-d1)/d1, and controlling the air conditioner to perform isothermal humidification treatment when the percentage value n1 is greater than or equal to the set value n in actual operation.
In a specific use process, if the current proportion is smaller than or equal to the set proportion, the water supply system is controlled to stop water supply and/or carry out dehumidification treatment.
For example: when the percentage n1 is smaller than the set value n during actual operation, the controller controls the electric adjusting water pump 4 to be closed, and the air conditioner controls the air conditioner to perform dehumidification treatment during refrigeration or dehumidification.
Therefore, under the condition that the difference value of the target moisture content required by a user and the return air mouth moisture content of the return air inlet of the air conditioning system accounts for the current proportion of the return air mouth moisture content to be larger than the set proportion, the humidification water consumption required by the water supply system is determined, the water supply system is controlled to supply water for humidification according to the humidification water consumption, the isothermal humidification treatment of the air conditioning system is realized, the humidification water consumption required by the air conditioning system is more accurately determined, and the method is simpler, more convenient and more reliable.
Alternatively, the specific process of determining the currently required amount of humidification water to be supplied by the water supply system in step S220 may further be described with reference to a flowchart of an embodiment of determining the currently required amount of humidification water to be supplied by the water supply system in the method of fig. 8, and may include: step S410 and step S420.

For example: acquiring the air supply volume G according to the set air speed v of the user, wherein the moisture content of the user is 1000G (d2-d 1); according to the air supply temperature t3 known by the air supply outlet temperature sensor, the current vaporization latent heat value r of the water at the temperature t3 can be obtained, and the water addition amount W is equal to Q/r, namely W is equal to 1000G (d2-d 1)/r.
Therefore, the target wind speed set by the user is acquired in various ways, and the acquisition way is flexible and convenient; and then the target air supply volume of the air conditioning system is determined according to the target air speed, and the target air supply volume and the preset coefficient times of the difference value between the target moisture content and the return air mouth moisture content are used as the target moisture content required by the user.
More optionally, a specific process of the step S410 of obtaining the current latent heat value of vaporization of water according to the current supply temperature of the air supply outlet of the air conditioning system (e.g. the supply air temperature t3) may further be described with reference to a flowchart of an embodiment of obtaining the current latent heat value of vaporization of water according to the current supply temperature of the air supply outlet of the air conditioning system (e.g. the supply air temperature t3) in the method of fig. 10, where the specific process may include: step S610 and step S620.
In step S610, a current air supply temperature and a current atmospheric pressure (for example, air supply temperature t3) of an air supply outlet of the air conditioning system, which are detected by a second temperature sensor arranged in an air supply passage or the air supply outlet of the air conditioning system, are acquired.
Step S620, according to the corresponding relation between the set air supply temperature and the set atmospheric pressure and the set vaporization latent heat value, taking the set vaporization latent heat value which is the same as the current air supply temperature and the current atmospheric pressure in the corresponding relation as the current vaporization latent heat value.
For example: arranging a temperature sensor in the air supply channel, and detecting the air supply temperature t 3; a temperature sensor and a relative humidity sensor are arranged in the return air channel, and the return air temperature t1 and the return air relative humidity phi 1 are detected; the temperature t2, the relative humidity value phi 2 and the air supply speed v which are expected by a user are obtained through a remote controller or a hand operator.
From this, through the current air supply temperature that detects air conditioning system's supply-air outlet, and then confirm the current latent heat value of vaporization of this current supply-air temperature offal water, be favorable to confirming the current required humidification water consumption according to the current latent heat value of vaporization of supply-air temperature offal water, and then realize isothermal humidification and handle, precision and reliability can all obtain guaranteeing to promote user's comfort and experience fabulously.
Step S420, using the ratio of the target moisture content to the vaporization latent heat value as the humidification water consumption currently required to be supplied by the water supply system, that is, the current water supply amount currently required to be supplied by the water supply system.
Therefore, the target moisture demand of the user is determined according to the target air speed set by the user, and the ratio of the target moisture demand to the vaporization latent heat value of water at the current air supply temperature of the air supply outlet of the air conditioning system is used as the humidification water consumption required by the water supply system, so that the humidification water consumption required by the water supply system is determined more simply and accurately, and the accuracy and the reliability of isothermal humidification treatment are guaranteed.
