Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning system capable of air conditioning a plurality of rooms in a house with one air conditioner.

Conventionally, a house is air-conditioned by a central air conditioner. In addition, with the increase in demand for energy-saving housing and the tightening of regulations, it is expected that the number of highly insulated and highly airtight houses will increase, and there is a demand for an air conditioning system suitable for these characteristics.

As such an air-conditioning system, the air conveyed from multiple spaces, etc. to the air-conditioned room is conditioned to a predetermined temperature and humidity in the air-conditioned room so that the temperature and humidity of the air in the multiple spaces (living room) become the target temperature and humidity. After that, there is known a central air-conditioning system that transports air to each of a plurality of spaces (for example, Patent Literature 1).

Japanese Patent Application Laid-Open No. 2020-63899

In a conventional central air-conditioning system, the temperature of the air in the air-conditioned room is controlled by the air conditioner installed in the air-conditioned room, and the humidity of the air in the air-conditioned room is controlled by the humidifier installed in the air-conditioned room. Humidification is controlled. Then, air that has been air-conditioned (temperature-controlled and humidified) by a blower (conveyance fan) installed in the air-conditioned room is conveyed to each living room. However, when the amount of air to be conveyed to each living room (the air volume of the blower) fluctuates, the amount of moisture supplied to each living room, that is, the humidity of each living room will accordingly fluctuate. For example, when the amount of air to be conveyed to each living room increases, the moisture contained in the air corresponding to the increased amount of air to be conveyed is excessively supplied to each living room, resulting in an increase in the humidity of each living room. . As described above, in the conventional central air-conditioning system, the humidity of the air in each living room may not be stably maintained at the target humidity. In other words, in the conventional central air-conditioning system, the amount of moisture supplied to each living room changes due to fluctuations in the air volume of the blower, and there is a problem that the humidification control by the humidifier is not stable.

SUMMARY OF THE INVENTION An object of the present invention is to provide an air conditioning system capable of controlling humidification by a humidifying device corresponding to fluctuations in air volume of a carrier fan.

In order to achieve this object, the air conditioning system according to the present invention includes an air conditioning room configured to allow air to be introduced from the outside, an air conditioner installed in the air conditioning room for controlling the temperature of the air in the air conditioning room, and A humidifying device that is installed and humidifies the air temperature-controlled by the air conditioner, a plurality of transfer fans that transfer the air in the air-conditioned room to a plurality of air-conditioned spaces independent of the air-conditioned room, and controls the humidifier and the transfer fan. and a controller for Then, the humidifying device is configured to centrifugally crush the water pumped by the rotation of the pumping pipe to make the water finer, to include the water in the air whose temperature is controlled by the air conditioner, and to discharge the water. The controller identifies the number of rotations of the pumping pipe based on the required amount of humidification of the air-conditioned space, the temperature of the air temperature-controlled by the air conditioner, and the air volume of the carrier fan. It is characterized by controlling the amount of humidification of temperature-controlled air.

According to the present invention, it is possible to provide an air-conditioning system capable of performing humidification control using a humidifier corresponding to fluctuations in the air volume of a carrier fan.

An air-conditioning system according to the present invention includes an air-conditioned room configured to allow air to be introduced from the outside, an air-conditioner installed in the air-conditioned room for controlling the temperature of the air in the air-conditioned room, and A humidifier for humidifying conditioned air, a plurality of transfer fans for transferring air in an air-conditioned room to a plurality of air-conditioned spaces independent of the air-conditioned room, and a controller for controlling the humidifier and the transfer fan. Then, the humidifying device is configured to centrifugally crush the water pumped by the rotation of the pumping pipe to make the water finer, to include the water in the air whose temperature is controlled by the air conditioner, and to discharge the water. The controller identifies the number of rotations of the pumping pipe based on the required amount of humidification of the air-conditioned space, the temperature of the air temperature-controlled by the air conditioner, and the air volume of the carrier fan. Controls the amount of humidification of temperature-controlled air.

According to such a configuration, even if the amount of air to be conveyed to the air-conditioned space fluctuates, the amount of humidification contained in the air to be conveyed to the air-conditioned space is adjusted accordingly, so that the air is supplied to the air-conditioned space. Fluctuations in the moisture content are suppressed, and the humidity of the air in the air-conditioned space can be stably maintained at the target humidity. In other words, it is possible to provide an air conditioning system that can perform humidification control using a humidifier that corresponds to fluctuations in the air volume of the carrier fan.

Further, in the air conditioning system according to the present invention, the controller performs control to decrease the rotation speed of the pumping pipe when the air volume of the carrier fan increases, and controls the rotation speed of the pumping pipe when the air volume of the carrier fan decreases. is controlled to increase As a result, when the air flow rate of the transfer fan increases, the amount of humidification included in the air transferred to the air-conditioned space decreases, and when the air flow rate of the transfer fan decreases, the amount of humidification included in the air transferred to the air-conditioned space decreases. Since the amount of humidification supplied to the air-conditioned space increases, it is possible to reliably suppress fluctuations in the amount of moisture supplied to the air-conditioned space due to fluctuations in the air volume of the carrier fan.

Further, in the air conditioning system according to the present invention, the pumping pipe can rotate in a range between the lower limit rotation speed and the upper limit rotation speed, and the controller determines that the amount of humidification that can be output at the upper limit rotation speed with respect to the required humidification amount is If it falls below, control is performed to increase the air volume of the carrier fan, and if the humidification quantity that can be output at the lower limit rotation speed exceeds the required humidification quantity, control may be performed to decrease the air volume of the carrier fan. By doing so, when the amount of humidification that can be output at the upper limit rotation speed is less than the required amount of humidification, the amount of air conveyed to the air-conditioned space increases. amount can be increased. On the other hand, when the amount of humidification that can be output at the lower limit rotation speed exceeds the required amount of humidification, the amount of air conveyed to the air-conditioned space decreases, so the amount of moisture supplied to the air-conditioned space is reduced. can be done. That is, in the air conditioning system, the adjustable range of the amount of humidification by the humidifier is widened, and highly accurate humidification adjustment is possible for the air whose temperature is controlled by the air conditioner.

In addition, the air conditioning system according to the present invention further includes a damper that adjusts the amount of air flowing into the humidifying device, and the controller is configured to be able to control the damper so that the amount of humidification that can be output at the lower limit rotation speed with respect to the required amount of humidification. If it exceeds, control may be performed to reduce the inflow air volume by a damper. As a result, when the amount of humidification that can be output at the lower limit rotation speed exceeds the required amount of humidification, the amount of humidification contained in the air conveyed to the air-conditioned space is further reduced. can be further reduced.

Next, the configuration of the humidifying device 16 will be described with reference to FIG. FIG. 2 is a schematic cross-sectional view of the humidifier 16 that constitutes the air conditioning system 20. As shown in FIG.

The humidifier 16 is located downstream of the air conditioner 13 in the air-conditioned room 18 and is a device for humidifying the air in the air-conditioned room 18 by centrifugal water crushing. In other words, the humidifier 16 is a device configured to centrifugally crush the water pumped up by the rotation of the pumping pipe 37 to make it finer, include it in the air temperature-controlled by the air conditioner 13, and release it. be.

The humidifier 16 includes an intake port 31 for sucking air in the air-conditioned room 18, an air outlet 32 for blowing out the humidified air into the air-conditioned room 18, and an air passage provided between the air inlet 31 and the air outlet 32. , and a liquid atomization chamber 33 provided in the air passage.

The suction port 31 is provided on the upper surface of the housing that constitutes the outer frame of the humidifying device 16, and the outlet 32 is provided on the side surface of the housing. The liquid atomization chamber 33 is a main part of the humidifier 16, and is where water is atomized by a centrifugal water crushing method. A suction port damper 15 is attached to the suction port 31 as shown in FIG.

Specifically, the humidifying device 16 includes a rotating motor 34, a rotating shaft 35 rotated by the rotating motor 34, a centrifugal fan 36, a cylindrical water pumping pipe 37, a water reservoir 40, a first eliminator 41, a second a secondary eliminator 42;

The pumping pipe 37 is fixed to the rotating shaft 35 inside the liquid atomization chamber 33 and pumps up water from a circular pumping port provided vertically downward while rotating as the rotating shaft 35 rotates. More specifically, the pumping pipe 37 has an inverted conical hollow structure, has a circular pumping opening vertically downward, and is located above the pumping pipe 37 at the center of the top surface of the inverted cone. , a rotating shaft 35 arranged in the vertical direction is fixed. The rotating shaft 35 is connected to the rotating motor 34 positioned vertically above the liquid atomization chamber 33, so that the rotating motion of the rotating motor 34 is transmitted to the pumping pipe 37 through the rotating shaft 35, and the pumping pipe 37 rotates. do.

The pumping pipe 37 also has a plurality of rotating plates 38 formed on the top surface side of the inverted conical shape so as to protrude outward from the outer surface of the pumping pipe 37 . The plurality of rotating plates 38 are formed to protrude outward from the outer surface of the pumping pipe 37 with a predetermined interval in the axial direction of the rotating shaft 35 between the vertically adjacent rotating plates 38 . Since the rotating plate 38 rotates together with the pumping pipe 37 , it is preferable that the rotating plate 38 has a horizontal disk shape coaxial with the rotating shaft 35 . The number of rotating plates 38 is appropriately set according to the target performance or the dimensions of the pumping pipe 37 .

Moreover, a plurality of openings 39 penetrating through the wall surface of the pumping pipe 37 are provided in the wall surface of the pumping pipe 37 . Each of the plurality of openings 39 is provided at a position where the inside of the pumping pipe 37 communicates with the upper surface of the rotating plate 38 formed to protrude outward from the outer surface of the pumping pipe 37 .

A centrifugal fan 36 is arranged vertically above the water pump 37 and is a fan for drawing air from the air-conditioned room 18 into the apparatus. The centrifugal fan 36 is fixed to the rotating shaft 35 like the pumping pipe 37 , and rotates with the rotation of the rotating shaft 35 to introduce air into the liquid atomization chamber 33 . The amount of air introduced into the humidifier 16 (the air introduced into the liquid atomization chamber 33 ) increases or decreases under the influence of the air volume of the carrier fan 3 .

The water storage unit 40 stores the water pumped up by the pumping pipe 37 from the pumping port below the pumping pipe 37 in the vertical direction. The depth of the reservoir 40 is designed such that a portion of the lower part of the pumping pipe 37, for example, about one-third to one-hundredth of the height of the cone of the pumping pipe 37, is submerged. . This depth can be designed according to the required pumping capacity. Moreover, the bottom surface of the water storage part 40 is formed in a mortar shape toward the pumping port. Water is supplied to the water storage unit 40 by a water supply unit (not shown).

The first eliminator 41 is a porous body through which air can flow, is provided on the side of the liquid atomization chamber 33 (outer periphery in the centrifugal direction), and is arranged so that air flows in the centrifugal direction. In the first eliminator 41 , the water droplets emitted from the opening 39 of the pumping pipe 37 collide with each other to make the water droplets finer and collect the water droplets contained in the air passing through the liquid atomization chamber 33 . do. As a result, the air flowing through the humidifier 16 contains only vaporized water.

The second eliminator 42 is provided on the downstream side of the first eliminator 41 and arranged so that air flows vertically upward. The first eliminator 41 is also a porous body through which air can flow, and collects droplets of the water contained in the air passing through the first eliminator 41 by colliding with the air passing through the first eliminator 41. do. As a result, water droplets having a large particle size can be collected more accurately by collecting the miniaturized water droplets doubly by the two eliminators.

Next, the operating principle of humidification (miniaturization of water) in the humidifier 16 will be described.

Next, with reference to FIG. 2, the principle of operation of humidification (miniaturization of water) in the humidifier 16 will be described. In FIG. 2, the arrows indicate the flow of air and the flow of water in the device.

First, when the operation of the humidifying device 16 is started, the rotating shaft 35 is rotated at the first rotation speed by the rotating motor 34 , and the centrifugal fan 36 starts sucking air from the air-conditioning chamber 18 through the suction port 31 . Then, the pumping pipe 37 rotates according to the rotation of the rotary shaft 35 at the first rotation speed. The centrifugal force generated by the rotation causes the water stored in the water reservoir 40 to be pumped up by the pumping pipe 37, like the flow of water indicated by the dashed arrows. Here, the first rotation speed of the rotary motor 34 (the pumping pipe 37) is set between 500 rpm and 3000 rpm, for example, according to the amount of blown air and the amount of humidification of the air. Since the pumping pipe 37 has an inverted conical hollow structure, the water pumped up by the rotation is pumped up along the inner wall of the pumping pipe 37 . The pumped water is discharged in the centrifugal direction through the opening 39 of the pumping pipe 37 along the rotating plate 38 and scatters as water droplets.

Water droplets scattered from the rotating plate 38 fly in the space (liquid atomization chamber 33) surrounded by the first eliminator 41, collide with the first eliminator 41, and are atomized. On the other hand, the air passing through the liquid atomization chamber 33 moves to the outer peripheral portion of the first eliminator 41 while containing the water that has been crushed (finely atomized) by the first eliminator 41, like the air flow indicated by the solid line arrows. . As the air flows through the air passage from the first eliminator 41 to the second eliminator 42, a vortex of the air current is generated and the water and the air are mixed. The water-laden air then passes through the second eliminator 42 . As a result, the humidifying device 16 can humidify the air sucked from the suction port 31 and blow the humidified air from the blowing port 32 .

The liquid to be atomized may be other than water, and may be, for example, hypochlorous acid water having sterilizing or deodorizing properties.

In addition, the processing unit 50c updates the display of the display panel 50j through the output unit 50i according to changes in the information displayed on the display panel 50j.

The damper opening degree specifying unit 50f acquires information about the required air conditioning amount from the processing unit 50c, and specifies the opening degrees of the living room dampers 5a to 5d based on the ratio of the required air conditioning amounts for each of the living rooms 2a to 2d. In addition, although the details will be described later, the damper opening degree identification unit 50f identifies the opening degree of the inlet damper 15 in accordance with the air blowing control operation of the carrier fan 3 . Then, the damper opening degree identification unit 50f outputs information (opening degree information) regarding the opening degree of the identified room dampers 5a to 5d and the opening degree of the inlet damper 15 to the processing unit 50c.

The air volume specifying unit 50g acquires information about the required air conditioning volume from the processing unit 50c, and specifies the air volume blown out from the air conditioner 13 based on the average value or the total value of the required air conditioning volume. Further, the air volume specifying unit 50g specifies the air volume of the carrier fan 3 (the carrier fan 3a, the carrier fan 3b) based on the average value or the total value of the air conditioning volume requirements of the first floor and the second floor. Then, the air volume identification unit 50g outputs information (blown air volume information) on the air volume blown by the specified air conditioner 13 and information on the air volume blown by the specified carrier fan 3 (air volume information) to the processing unit 50c.

The set temperature specifying unit 50h acquires information about the required air conditioning amount from the processing unit 50c, and specifies the set temperature of the air conditioner 13 based on the average value or the total value of the required air conditioning amounts. Then, the set temperature identification unit 50h outputs information (air conditioner set temperature information) regarding the identified set temperature of the air conditioner 13 to the processing unit 50c.

The rotation speed identification unit 50k acquires information on the required air conditioning amount, information on the intake temperature of the humidifier 16, and air flow information from the processing unit 50c, and determines the rotation speed of the water pump 37 (rotary motor 34) of the humidifier 16.

Then, the processing unit 50c outputs the specified control information to the output unit 50i.

The output unit 50i outputs the control information received from the processing unit 50c to the air conditioner 13, the carrier fan 3 (the carrier fan 3a, the carrier fan 3b), the room damper 5 (the room dampers 5a to 5d), the inlet damper 15, and the , and the humidifier 16, respectively.

Then, according to the control information output from the output unit 50i, the air conditioner 13 performs the air conditioning operation with the air conditioning set temperature and blowing air volume based on the control information. In addition, the carrier fan 3 (the carrier fan 3a, the carrier fan 3b) executes the air blowing operation with each blowing amount based on the control information output from the output unit 50i. In addition, the living room dampers 5 (the living room dampers 5a to 5d) perform air volume adjustment operations at respective opening degrees based on the control information output from the output unit 50i.

In addition, the humidifying device 16 rotates the water pump 37 at the number of rotations based on the control information output from the output unit 50i.

As described above, the controller 50 causes the air conditioner 13, the carrier fan 3, the living room damper 5, the inlet damper 15, and the humidifier 16 to operate.

Next, basic operations of the controller 50 will be described with reference to FIG. FIG. 4 is a flow chart showing the basic processing operation of the controller 50. As shown in FIG.

First, the controller 50 performs a termination determination of the air conditioning system 20 (step S01). As a result, if the air conditioning system 20 is powered off (or an instruction to stop the operation of the air conditioning system 20 is input from the operation panel 50a) (YES in step S01), the operation of the air conditioning system 20 ends. On the other hand, if the air conditioning system 20 is powered on (NO in step S01), it is determined whether time has elapsed (step S02). As a result, if a certain period of time (for example, 10 minutes) has not elapsed since the previous process (NO in step S02), the controller 50 returns to step S01. On the other hand, if a certain period of time has passed since the previous process (YES in step S02), the process advances to step S03 to perform the output specifying process of room damper 5, air conditioner 13, and carrier fan 3. FIG.

First, the controller 50 starts a loop for the number of living rooms 2 (step S03). The controller 50 then calculates the required air conditioning amounts for each of the living rooms 2a to 2d (step S04). The controller 50 also specifies the opening degrees of the living room dampers 5a to 5d corresponding to the living rooms 2a to 2d, respectively (step S05). Then, the controller 50 ends the loop when the calculation of the required air conditioning amounts for all the rooms 2 and the specification of the opening degrees of the room dampers 5 are completed (step S06).

The processing in the loop of steps S03 to S06 will be described in more detail by taking the living room 2a as an example.

In step S04, the controller 50 specifies the required air conditioning amount of the living room 2a as the temperature difference between the living room temperature acquired from the living room temperature sensor 11a and the living room set temperature set for the living room 2a. More specifically, the required air conditioning amount is specified based on the value obtained by subtracting the living room temperature from the living room temperature setting during heating operation, and is specified based on the value obtained by subtracting the living room temperature setting from the living room temperature during cooling operation. . This means that the greater the positive value of the required air-conditioning amount, the more air-conditioning is required in the living room 2a.

In step S05, the degree of opening of the damper 5a for the living room corresponding to the living room 2a is specified according to the required air conditioning amount of the living room 2a. In the present embodiment, when the required air conditioning amount is 2°C or higher, the degree of opening is set to "100%"; The degree of opening is "45%", the degree of opening is "50%" when the temperature is -1°C or more and less than 0°C, and the degree of opening is "10%" when the temperature is less than -1°C. By setting in this way, the degree of opening of the room dampers 5a to 5d is set according to the ratio of the required air conditioning amounts of the rooms 2a to 2d, and the room with the higher required air conditioning amount (room 2) is more air-conditioned. Air is blown, and temperature control for each living room 2 becomes possible.

Next, the controller 50 calculates the required air conditioning amount for the entire general house 1 based on the required air conditioning amount for each living room 2 (step S07). In this embodiment, the required air-conditioning amount of the general house 1 is calculated based on the average value of the required air-conditioning amounts of the living rooms 2 .

Subsequently, the controller 50 specifies the air conditioning set temperature and the blown air volume of the air conditioner 13 according to the calculated required air conditioning volume of the general house 1 (step S08). More specifically, the controller 50 sets the air conditioning set temperature higher as the required air conditioning amount increases during heating operation, and lowers the air conditioning set temperature as the required air conditioning amount increases during cooling operation. For example, if the required air conditioning amount is less than 0°C, the controller 50 sets the air conditioning set temperature to the same value as the room set temperature of the living room 2, and if the required air conditioning amount is 0°C or more and less than 1°C, the air conditioning set temperature is set to the same value. The living room set temperature of the living room 2 is made higher by 1 degree during heating operation and lower by 1 degree during cooling operation. Further, when the required air conditioning amount is 1° C. or more, the controller 50 sets the air conditioning set temperature of the living room 2 to be 2 degrees higher than the living room set temperature during the heating operation and 2 degrees lower during the cooling operation. As a result, the air conditioner 13 operates at a higher output as the required air conditioning amount increases, and the living room temperature of the living room 2 is controlled to the living room set temperature more quickly.

In addition, the controller 50 controls the blowing air volume of the air conditioner 13 to be larger as the required air conditioning volume is higher. In the present embodiment, when the required air conditioning amount is less than 0° C., the blown air volume is 500 m ³ /h, and when the required air conditioning volume is 0° C. or more and less than 1° C., the blown air volume is 700 m ³ /h. When the air-conditioning amount is 2° C. or higher, the blown air amount is 1200 m ³ /h.

Subsequently, the controller 50 determines the total air volume of the carrier fan 3 to be equal to or slightly larger than the air volume blown from the air conditioner 13 (step S09). In other words, the controller 50 specifies that the air volume difference between the total air volume of the carrier fan 3 and the air volume blown out from the air conditioner 13 is equal to or less than the reference air volume. Thereby, the controller 50 suppresses the power consumption of the transfer fan 3 .

Next, the controller 50 calculates the required air conditioning amounts for each of the first and second floors (step S10). In this embodiment, the average value of the required air-conditioning amounts of the living rooms 2 on the first and second floors is used as the required air-conditioning amount for that floor.

Subsequently, based on the required air conditioning amount calculated in step S10, the blowing amount of the conveying fan 3 is specified (step S11). The controller 50 specifies the air volume of each of the carrier fans 3 on the first floor and the second floor so as to provide an air volume ratio corresponding to the ratio of the required air conditioning volume. Specifically, when the required air conditioning amount for the second floor is 1° C., the required air conditioning amount for the first floor is 2° C., and the total air volume of the transfer fan 3 specified in step S09 is 1200 m ³ /h, The air volume of the carrier fan 3a on the second floor is specified to be 400 m ³ /h, and the air volume of the carrier fan 3b on the first floor is specified to be 800 m ³ /h so that the air volume ratio between the carrier fans 3 is 1:2. As a result, even if there is a difference in the amount of air conditioning required between the first floor and the second floor, the difference in the amount of air blown by the transfer fan 3 causes a difference in the amount of heat to be conveyed. A suitable amount of heat can be transported.

Subsequently, the controller 50 starts humidification control (step S12).

Next, humidification control will be described with reference to FIGS. 5 and 6. FIG. FIG. 5 is a flow chart showing the humidification control operation of the controller. FIG. 6 is a diagram showing humidification performance data of the humidifier 16. As shown in FIG.

When humidification control is started, the controller 50 starts a loop corresponding to the number of living rooms 2, which are spaces to be air-conditioned (step S21). Then, the controller 50 calculates the required humidification amount for each of the living rooms 2a to 2d (step S22). Then, the controller 50 ends the loop when the calculation of the required humidification amounts for all the living rooms 2 is completed (step S23).

The processing in the loop of steps S21 to S23 will be described in more detail using the room 2a as an example.

In step S22, the controller 50 specifies the required humidification amount of the living room 2a as the humidity difference between the living room humidity acquired from the living room humidity sensor 12a and the living room set humidity set for the living room 2a. Specifically, the room set humidity and the room humidity are each converted into absolute humidity, and the value obtained by subtracting the room absolute humidity from the room set absolute humidity is defined as the required humidification amount. This means that the larger the positive value of the required humidification amount, the more humidification is required in the living room 2a.

Next, the controller 50 calculates the required humidification amount of the entire general house 1 based on the required humidification amount of each living room 2 (step S24). In the present embodiment, the required air conditioning amount of the general house 1 is calculated based on the average value of the required humidification amounts of the living rooms 2 .

Next, the controller 50 performs operation determination of the humidifier 16 (step S25). Specifically, when the required humidification amount of the general house 1 is positive (YES in step S25), the humidifier 16 is operated, and the process proceeds to step S26. If the required humidification amount of the general house 1 is 0 or negative (NO in step S25), the rotation speed of the water pumping pipe 37 is set to "0" and the humidification device 16 is not operated (step S28), and the humidification control ends. do.

Subsequently, the controller 50 specifies the required rotation speed of the water pump 37 according to the calculated required air conditioning amount of the general house 1, the suction temperature to the humidifier 16, and the total air volume of the carrier fan 3 (step S26). In this step S26, the controller 50 sets the required number of revolutions higher as the required humidification amount is higher, the suction temperature is lower, or the total air volume of the transport fan 3 is smaller.

In the present embodiment, the controller 50 specifies the required rotation speed based on the humidification performance data of the humidifier 16 shown in FIG. The humidification performance data is data obtained in advance by experiments, and the humidification performance data generated by the humidification device 16 when the humidification operation is performed under the conditions of the suction temperature T, the rotation speed R of the pumping pipe 37, and the total air volume Q of the transfer fan 3. Quantity X is shown. Here, the amount of humidification X emitted by the humidifier 16 corresponds to the amount of water contained in the air flowing through the humidifier 16 . Due to the characteristics of the humidifier 16, the suction temperature T, the number of revolutions R, and the total air volume Q have a positive correlation with the humidification amount X, respectively. For example, when the total air volumes Q1 and Q2 are in the relationship of Q1<Q2, and the temperature is T1 and the rotational speed is R1, the relative magnitude of the humidification amounts X1 and X2 is X1<X2.

Next, the details of the method for specifying the required number of revolutions from the humidification performance data will be described. First, a regression formula relating to the amount of humidification X is created from table data, and formula (1) in FIG. 6 is obtained. Next, the generated regression equation is transformed so that the number of rotations R is on the left side to obtain equation (2) in FIG. Then, assuming that the intake temperature T is the intake temperature from the intake temperature sensor 14, the total air volume Q is the total air volume of the carrier fan 3, and the humidification amount X is the required humidification amount X' of the general house 1, the right side of equation (2) is calculated. , the required rotation speed is calculated. Although the regression formula of formula (1) is a combination of linear terms of the rotation speed R, the suction temperature T, and the total air volume Q, in order to improve the accuracy of the regression, the rotation speed R, the suction temperature T, and the total air volume Q any second or higher term may be included.

Subsequently, when the required rotation speed exceeds the preset upper limit rotation speed, the controller 50 specifies the upper limit rotation speed as the rotation speed of the pumping pipe 37, and the required rotation speed falls below the preset lower limit rotation speed. In this case, the lower limit number of revolutions is specified as the number of revolutions of the pumping pipe 37 (step S27).

As a result, when the total air volume Q of the transfer fan 3 increases while the required humidification amount X′ and the suction temperature T are constant, the rotation speed R of the water pumping pipe 37 is controlled to decrease. less humidification in the air delivered to the Similarly, when the required humidification amount X′ and the suction temperature T are constant and the total air volume Q of the transfer fan 3 decreases, control is performed to increase the rotation speed R of the water pumping pipe 37. increases the amount of humidification contained in the air conveyed to the In other words, even if the total air volume Q of the carrier fan 3 fluctuates and the volume of air carried to each living room 2 fluctuates, the amount of air carried to each living room 2 varies according to the fluctuation of the total air volume Q of the carrier fan 3. Since the amount of humidification to be applied is adjusted, fluctuations in the amount of moisture supplied to each classroom 2 are suppressed.

Here, if the required rotation speed exceeds the upper limit rotation speed, it means that the amount of humidification that can be output at the upper limit rotation speed is insufficient for the required humidification amount, and the required rotation speed is lower than the lower limit rotation speed. If it is, it means that the amount of humidification that can be output at the lower limit rotation speed is excessive with respect to the required amount of humidification.

Next, in these cases, a method of eliminating excessive or insufficient humidification by adjusting the total air volume Q of the transfer fan 3 or adjusting the opening of the inlet damper 15 will be described.

First, with reference to FIG. 7, a processing operation for air volume correction of the conveying fan 3 in humidification control will be described. FIG. 7 is a flow chart showing the conveying fan air volume correction processing of the controller 50 .

First, when the required rotation speed exceeds the upper limit rotation speed (YES in step S31), the controller 50 increases the total air volume Q of the transport fan 3 at a predetermined rate (for example, 1.1 times) (step S32). If the required rotation speed is equal to or lower than the upper limit rotation speed (NO in step S31), it is determined whether the required rotation speed is lower than the lower limit rotation speed (step S33). If the required rotation speed is lower than the lower limit rotation speed (YES in step S33), the total air volume Q of the transport fan 3 is decreased by a predetermined ratio (for example, 0.9 times) (step S34). In this embodiment, the total air volume Q of the conveying fan 3 is set to be equal to the air volume of the air conditioner 13. Increase or decrease to equal the total airflow of fan 3. By doing so, the amount of air flowing into the humidifier 16 can be changed without changing the temperature of the air sucked into the humidifier 16 . As a result, when the amount of humidification that can be output at the upper limit rotation speed is less than the required amount of humidification, the amount of air to be conveyed to each living room 2 increases. Further, when the amount of humidification that can be output at the lower limit rotation speed exceeds the required amount of humidification, the amount of air to be conveyed to each living room 2 decreases. In addition, the total air volume Q of the transfer fan 3 after correction is obtained by solving the equation (1) for the total air volume Q, the humidification amount X being the required humidification amount of the general house 1, the rotation speed R being the upper limit rotation speed, and the suction temperature T being the suction temperature. You may specify by substituting and calculating as the suction temperature from the temperature sensor 14, respectively.

Next, control of the suction port damper 15 will be described with reference to FIG. FIG. 8 is a flow chart showing the suction inlet damper control operation of the controller 50 .

First, the controller 50 determines whether the required rotation speed is below the lower limit rotation speed (step S41). Then, as a result of the determination, if the required rotation speed is lower than the lower limit rotation speed (YES in step S41), the opening of the suction port damper 15 is reduced to, for example, "50%" (step S42), and the humidifying device 16 is reduced. On the other hand, if the result of determination is that the required rotation speed is equal to or higher than the lower limit rotation speed (NO in step S41), the opening of the suction port damper 15 is set to "100%" (step S43), and the air flowing into the humidifier 16 is do not impede As a result, when the required rotation speed is lower than the lower limit rotation speed, the degree of opening of the suction port damper 15 is reduced, so that the amount of air flowing into the humidifier 16 is reduced, and the humidification included in the air conveyed to each living room 2 is reduced. quantity is further reduced.

As described above, according to the air conditioning system 20 according to the first embodiment, the following effects can be obtained.

(1) The air conditioning system 20 includes an air conditioning room 18 configured to allow air to be introduced from the outside, an air conditioner 13 installed in the air conditioning room 18 to control the temperature of the air in the air conditioning room 18, and an air conditioner 13 installed in the air conditioning room 18. a humidifying device 16 for humidifying the air temperature-controlled by the air conditioner 13; a plurality of transfer fans 3 for transferring the air in the air-conditioned room 18 to a plurality of living rooms 2 independent of the air-conditioned room 18; and a controller 50 that controls the transfer fan 3 . The humidifying device 16 is configured to centrifugally crush the water pumped by the rotation of the water pumping pipe 37 to make the water fine, and to include the water in the air whose temperature is controlled by the air conditioner 13 and release it. The controller 50 specifies the number of revolutions of the water pumping pipe 37 (rotary motor 34) based on the required amount of humidification of the living room 2, the temperature of the air temperature-controlled by the air conditioner 13, and the air volume of the carrier fan 3, The amount of humidification of the air temperature-controlled by the air conditioner 13 is controlled by the specified number of revolutions.

As a result, even if the amount of air to be conveyed to each living room 2 fluctuates, the amount of humidification included in the air to be conveyed to each living room 2 is adjusted accordingly. Fluctuations are suppressed, and the humidity of the air in each living room 2 can be stably maintained at the target humidity. In other words, the air conditioning system 20 can be configured to be able to perform humidification control by the humidifier 16 corresponding to fluctuations in the air volume of the carrier fan 3 .

(2) In the air conditioning system 20, the controller 50 performs control to decrease the rotation speed of the water pump 37 when the air volume of the carrier fan 3 increases, and when the air volume of the carrier fan 3 decreases, the controller 50 I tried to control to increase the number of revolutions. As a result, when the air volume of the transport fan 3 increases, the amount of humidification included in the air transported to each living room 2 decreases, and when the air volume of the transport fan 3 decreases, the air transported to each living room 2 Since the amount of humidification to be contained in the room increases, it is possible to reliably suppress fluctuations in the amount of moisture supplied to each living room 2 due to fluctuations in the air volume of the carrier fan 3 .

(3) In the air conditioning system 20, the pumping pipe 37 is rotatable in a range between the lower limit rotation speed and the upper limit rotation speed, and the controller 50 determines that the amount of humidification that can be output at the upper limit rotation speed with respect to the required humidification amount is When it falls below, control is performed to increase the air volume of the conveying fan 3, and when the humidification quantity that can be output at the lower limit rotational speed exceeds the required humidification quantity, control is performed to decrease the air volume of the conveying fan 3. - 特許庁As a result, when the amount of humidification that can be output at the upper limit rotation speed is less than the required amount of humidification, the amount of air conveyed to each living room 2 increases, so the amount of moisture supplied to each living room 2 is increased. be able to. On the other hand, when the amount of humidification that can be output at the lower limit rotation speed exceeds the required amount of humidification, the amount of air conveyed to each living room 2 decreases, so the amount of moisture supplied to each living room 2 should be reduced. can be done. That is, in the air-conditioning system 20, the adjustable range of the amount of humidification by the humidifier 16 is widened, and high-precision humidification adjustment for the air temperature-controlled by the air conditioner 13 is possible.

(4) The air-conditioning system 20 further includes an inlet damper 15 that adjusts the amount of air flowing into the humidifier 16. The controller 50 is configured to be able to control the inlet damper 15, and controls the lower limit number of rotations with respect to the required humidification amount. When the amount of humidification that can be output exceeds the amount of humidification that can be output by the suction port damper 15, control is performed to reduce the amount of inflow air. As a result, when the amount of humidification that can be output at the lower limit rotation speed exceeds the required amount of humidification, the amount of humidification included in the air conveyed to each living room 2 is further reduced, so the amount of moisture supplied to each living room 2 can be further reduced.
