Description

[Technical field]

[0001] The present invention relates to an air conditioning system that makes it possible to air-condition multiple rooms in a house with a single air conditioner. [Background technology]

[0002] Traditionally, homes have been air-conditioned using central air conditioners. However, with the growing demand for energy-saving homes and stricter regulations, it is expected that the number of highly insulated and airtight homes will increase, and there is a demand for air-conditioning systems that are suited to these characteristics.

[0003] One such air conditioning system known is a whole-building air conditioning system, which conditions air transported from multiple spaces (rooms) to an air-conditioned room to a predetermined temperature and humidity in the air-conditioned room and then transports the air to each of the multiple spaces (rooms) so that the air temperature and humidity in the multiple spaces become target temperature and humidity (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2020-63899 A Summary of the Invention [Problem to be solved by the invention]

[0005] In a conventional central air-conditioning system, the temperature of the air in the air-conditioning room is controlled by an air conditioner (air conditioner) installed in the air-conditioning room, and the humidity of the air in the air-conditioning room is controlled by a humidifier also installed in the air-conditioning room. Then, the conditioned (temperature-controlled and humidified) air is transported to each room by a blower (transport fan) installed in the air-conditioning room. However, if the amount of air transported to each room (air volume of the blower) fluctuates, the amount of moisture supplied to each room, that is, the humidity of each room, will fluctuate accordingly. For example, if the amount of air transported to each room increases, the moisture contained in the air of the increased amount is excessively supplied to each room, and the humidity of each room will increase. In this way, in a conventional central air-conditioning system, the humidity of the air in each room may not be stably maintained at the target humidity. In other words, with conventional central air conditioning systems, the amount of moisture supplied to each room changes due to fluctuations in the blower's airflow, resulting in unstable humidification control by the humidifier.

[0006] The present invention has been made to solve the above-mentioned problems, and provides an air conditioning system capable of controlling humidification by a humidifier in response to fluctuations in the air volume of a transport fan. [Means for solving the problem]

[0007] To achieve this object, the air conditioning system according to the present invention comprises an air-conditioned room configured to be able to introduce air from the outside, an air conditioner installed in the air-conditioned room and adjusting the temperature of the air in the air-conditioned room, a humidifier installed in the air-conditioned room and humidifying the air adjusted in temperature by the air conditioner, a plurality of transport fans that transport the air in the air-conditioned room to a plurality of conditioned spaces independent of the air-conditioned room, and a controller that controls the humidifier and the transport fans. The humidifier is configured to centrifugally crush and finely disperse water pumped by the rotation of the lift pipe, and release the water by including it in the air adjusted in temperature by the air conditioner. The controller specifies the number of revolutions of the lift pipe based on the required amount of humidification of the conditioned space, the temperature of the air adjusted in temperature by the air conditioner, and the air volume of the transport fan, and controls the amount of humidification of the air adjusted in temperature by the air conditioner using the specified number of revolutions.The controller controls the rotation speed of the water lift pipe to decrease when the air volume of the transport fan increases, and controls the rotation speed of the water lift pipe to increase when the air volume of the transport fan decreases. The present invention is characterized by the following: Effect of the Invention

[0008] According to the present invention, it is possible to provide an air conditioning system capable of controlling humidification by a humidifier in response to fluctuations in the air volume of a transport fan. [Brief description of the drawings]

[0010] The air conditioning system according to the present invention includes an air-conditioned room configured to be able to introduce air from the outside, an air conditioner installed in the air-conditioned room and controlling the temperature of the air in the air-conditioned room, a humidifier installed in the air-conditioned room and humidifying the air temperature-controlled by the air conditioner, a plurality of transport fans that transport the air in the air-conditioned room to a plurality of conditioned spaces independent of the air-conditioned room, and a controller that controls the humidifier and the transport fan. The humidifier is configured to centrifugally crush and finely disperse water pumped by the rotation of the lift pipe, and to include the water in the air temperature-controlled by the air conditioner and release the water. The controller specifies the number of revolutions of the lift pipe based on the required amount of humidification of the conditioned space, the temperature of the air temperature-controlled by the air conditioner, and the air volume of the transport fan, and controls the amount of humidification of the air temperature-controlled by the air conditioner based on the specified number of revolutions.

[0011] With this configuration, even if the volume of air transported to the conditioned space fluctuates, the volume of humidification added to the air transported to the conditioned space is adjusted accordingly, suppressing fluctuations in the amount of moisture supplied to the conditioned space and enabling the humidity of the air in the conditioned space to be stably maintained at a target humidity. In other words, an air conditioning system can be provided that is capable of controlling humidification using a humidifier in response to fluctuations in the volume of air flow from the transport fan.

[0012] In the air conditioning system according to the present invention, the controller controls the rotation speed of the lift pipe to decrease when the air volume of the transport fan increases, and controls the rotation speed of the lift pipe to increase when the air volume of the transport fan decreases. As a result, when the air volume of the transport fan increases, the amount of humidification added to the air transported to the conditioned space decreases, and when the air volume of the transport fan decreases, the amount of humidification added to the air transported to the conditioned space increases, so that it is possible to reliably suppress fluctuations in the amount of moisture supplied to the conditioned space due to fluctuations in the air volume of the transport fan.

[0013] In the air conditioning system according to the present invention, the pumping pipe can rotate within a range between the lower limit rotation speed and the upper limit rotation speed, and the controller may control the conveying fan to increase the air volume when the humidification amount that can be output at the upper limit rotation speed is lower than the required humidification amount, and control the conveying fan to decrease the air volume when the humidification amount that can be output at the lower limit rotation speed is higher than the required humidification amount. In this way, when the humidification amount that can be output at the upper limit rotation speed is lower than the required humidification amount, the conveying amount of air conveyed to the conditioned space increases, so that the amount of moisture supplied to the conditioned space can be increased. On the other hand, when the humidification amount that can be output at the lower limit rotation speed is higher than the required humidification amount, the conveying amount of air conveyed to the conditioned space decreases, so that the amount of moisture supplied to the conditioned space can be decreased. In other words, in the air conditioning system, the range in which the humidification amount can be adjusted by the humidifier is expanded, and highly accurate humidification adjustment is possible for the air whose temperature is adjusted by the air conditioner.

[0014] The air conditioning system according to the present invention may further include a damper for adjusting the amount of air flowing into the humidifier, and the controller may be configured to control the damper and perform control to reduce the amount of air flowing in when the amount of humidification that can be output at the lower limit rotation speed exceeds the required amount of humidification. This further reduces the amount of humidification to be added to the air transported to the conditioned space when the amount of humidification that can be output at the lower limit rotation speed exceeds the required amount of humidification, thereby further reducing the amount of moisture supplied to the conditioned space.

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0016] (Embodiment 1) First, an air conditioning system 20 according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a schematic connection diagram of the air conditioning system 20 according to the first embodiment of the present invention.

[0017] The air conditioning system 20 includes a plurality of transport fans 3 (transport fans 3a and 3b), a heat exchange fan 4, a plurality of occupant room dampers 5 (occupant room dampers 5a, 5b, 5c and 5d), a plurality of circulation ports 6 (circulation ports 6a, 6b, 6c and 6d), a plurality of occupant room exhaust ports 7 (occupant room exhaust ports 7a, 7b, 7c and 7d), a plurality of occupant room supply ports 8 (occupant room supply ports 8a, 8b, 8c and 8d), and an occupant room temperature control unit. The system is equipped with a temperature sensor 11 (room temperature sensors 11a, 11b, 11c, 11d), a room humidity sensor 12 (room humidity sensors 12a, 12b, 12c, 12d), an air conditioner (air conditioner) 13, an intake temperature sensor 14, an intake damper 15, a humidifier 16, a dust collection filter 17, and a controller 50 (corresponding to an air conditioning controller).

[0018] The air conditioning system 20 is installed in a general house 1, which is an example of a building. The general house 1 has a plurality of (four in this embodiment) rooms 2 (rooms 2a, 2b, 2c, 2d), and at least one air-conditioned room 18 that is independent of the rooms 2. Here, the general house 1 (house) is a residence provided as a place for residents to live private lives, and the rooms 2 generally include a living room, dining room, bedroom, private room, children's room, etc. Furthermore, the rooms provided by the air conditioning system 20 may include a toilet, bathroom, washroom, dressing room, etc.

[0019] Here, the living room 2a is provided with a circulation port 6a, a living room exhaust port 7a, a living room intake port 8a, a living room temperature sensor 11a, a living room humidity sensor 12a, and a controller 50. The living room 2b is provided with a circulation port 6b, a living room exhaust port 7b, a living room intake port 8b, a living room temperature sensor 11b, and a living room humidity sensor 12b. The living room 2c is provided with a circulation port 6c, a living room exhaust port 7c, a living room intake port 8c, a living room temperature sensor 11c, and a living room humidity sensor 12c. The living room 2d is provided with a circulation port 6d, a living room exhaust port 7d, a living room intake port 8d, a living room temperature sensor 11d, and a living room humidity sensor 12d.

[0020] Meanwhile, in air-conditioned room 18, there are disposed transport fan 3a, transport fan 3b, occupant room damper 5a, occupant room damper 5b, occupant room damper 5c, occupant room damper 5d, air conditioner 13, suction temperature sensor 14, suction port damper 15, humidifier 16, and dust collection filter 17. More specifically, from the upstream side of the circulation path of the air flowing in air-conditioned room 18, there are disposed air conditioner 13, dust collection filter 17, suction temperature sensor 14, suction port damper 15, humidifier 16, transport fan 3 (transport fans 3a, 3b), and occupant room damper 5 (occupant room dampers 5a, 5b, 5c, 5d) in this order.

[0021] Air is introduced from the outside of the air-conditioning room 18 to the inside of the air-conditioning room 18. In the air-conditioning room 18, air (indoor air) transported from each living room 2 through the circulation port 6 is mixed with outside air (outdoor air) taken in by the heat exchange fan 4 and heat-exchanged. The temperature and humidity of the air in the air-conditioning room 18 are controlled by the air conditioner 13 and the humidifier 16 installed in the air-conditioning room 18, that is, the air is conditioned to generate air to be transported to the living room 2. The air conditioned in the air-conditioning room 18 is transported to each living room 2 by the transport fan 3. Here, the air-conditioning room 18 means a space having a certain size in which the air conditioner 13, the intake temperature sensor 14, the intake port damper 15, the humidifier 16, the dust collection filter 17, etc. can be arranged and the air conditioning of each living room 2 can be controlled, but it is not intended as a living space and does not basically mean a room where a resident stays.

[0022] The air from each room 2 is transported to the air-conditioned room 18 through the circulation port 6, and is also heat-exchanged through the heat exchange fan 4 through the room exhaust port 7 before being discharged outdoors. The air-conditioning system 20 performs ventilation using a first type ventilation method by discharging inside air (indoor air) from each room 2 through the heat exchange fan 4 while taking in outside air (outdoor air) into the room. The ventilation air volume of the heat exchange fan 4 can be set in multiple stages, and the ventilation air volume is set to meet the required ventilation volume stipulated by law.

[0023] Heat exchange fan 4 is configured with an intake fan and an exhaust fan (not shown) inside, and by operating each fan, ventilation is performed while exchanging heat between the inside air (indoor air) and the outside air (outdoor air). At this time, heat exchange fan 4 transports the outside air that has been heat exchanged to air-conditioned room 18.

[0024] The transport fan 3 is provided on a wall surface (wall surface on the bottom side) of the air-conditioned room 18. The air in the air-conditioned room 18 is transported by the transport fan 3 through a transport duct from the room air supply port 8 to the room 2. More specifically, the air in the air-conditioned room 18 is transported by the transport fan 3a to the room 2a and the room 2b located on the first floor of the general house 1, and is transported by the transport fan 3b to the room 2c and the room 2d located on the second floor of the general house 1. The transport ducts connected to the room air supply port 8 of each room 2 are provided independently.

[0025] When transporting air from the transport fan 3 to each resident's room 2, the resident's room dampers 5 adjust the amount of air sent to each resident's room 2 by adjusting the opening degree of the resident's room dampers 5. More specifically, the resident's room damper 5a adjusts the amount of air sent to resident's room 2a located on the first floor, the resident's room damper 5b adjusts the amount of air sent to resident's room 2b located on the first floor, the resident's room damper 5c adjusts the amount of air sent to resident's room 2c located on the second floor, and the resident's room damper 5d adjusts the amount of air sent to resident's room 2d located on the second floor.

[0026] A portion of the air in each living room 2 (living rooms 2a to 2d) is transported to the air-conditioning room 18 through the corresponding circulation ports 6 (circulation ports 6a to 6d) via the circulation duct. Here, the air transported through the circulation ports 6 is naturally transported to the air-conditioning room 18 as circulating air by the difference between the air volume (supply air volume) transported from the air-conditioning room 18 to each living room 2 by the transport fan 3 and the air volume (exhaust air volume) exhausted to the outside from the living room exhaust port 7 by the heat exchange fan 4. Note that the circulation ducts connecting the air-conditioning room 18 and each living room 2 may be provided independently, or multiple branch ducts that are part of the circulation duct may be joined midway to be integrated into one circulation duct, which is then connected to the air-conditioning room 18.

[0027] As described above, each circulation port 6 (circulation ports 6a to 6d) is an opening for conveying indoor air from each room 2 (rooms 2a to 2d) to the air-conditioned room .

[0028] Each room exhaust vent 7 (room exhaust vents 7a to 7d) is an opening for conveying indoor air from each room 2 (rooms 2a to 2d) to the heat exchange fan 4, as described above.

[0029] As described above, each room air supply port 8 (room air supply ports 8a to 8d) is an opening for conveying air within air-conditioned room 18 from air-conditioned room 18 to each room 2 (rooms 2a to 2d).

[0030] The room temperature sensors 11 (room temperature sensors 11a to 11d) are sensors that obtain the room temperature of each of the corresponding rooms 2 (rooms 2a to 2d) and transmit the same to the controller 50.

[0031] The room humidity sensors 12 (room humidity sensors 12a to 12d) are sensors that obtain the room humidity (indoor humidity) of the corresponding rooms 2 (rooms 2a to 2d) and transmit it to the controller 50.

[0032] The air conditioner 13 corresponds to an air conditioner and controls the air conditioning of the air-conditioned room 18. The air conditioner 13 cools or heats the air in the air-conditioned room 18 so that the temperature of the air in the air-conditioned room 18 becomes a set temperature (air-conditioned room target temperature). Here, the set temperature is set to a temperature based on the result of calculating a required air conditioning amount from the temperature difference between the target temperature (room target temperature) set by the user and the room temperature. In this embodiment, the set temperature is set to a temperature at least higher than the target temperature in order to adjust the air temperature in each room 2 to the target temperature more quickly.

[0033] The suction temperature sensor 14 is a sensor that acquires the temperature of air conditioned by the air conditioner 13 in the air-conditioned room 18 and transmits it to the controller 50. More specifically, the suction temperature sensor 14 is installed downstream of the dust collection filter 17 in the air-conditioned room 18, acquires the temperature of the air being sucked into the humidifier 16, and transmits it to the controller 50.

[0034] The intake port damper 15 is installed corresponding to the intake port 31 of the humidifier 16 described later, and when air inside the air-conditioned room 18 is sucked in through the intake port 31, the amount of air flowing into the inside of the humidifier 16 is adjusted by adjusting the opening degree of the intake port damper 15.

[0035] The humidifier 16 is located downstream of the air conditioner 13 (and dust collection filter 17) in the air-conditioned room 18, and when the humidity of the air in each room 2 (room humidity) is lower than a target humidity (room target humidity) set by the user, the humidifier 16 humidifies the air in the air-conditioned room 18 so that the humidity becomes the target humidity. The humidities handled here are each indicated as relative humidity, but may be handled as absolute humidity by a predetermined conversion process. In this case, it is preferable to handle the entire handling in the air-conditioning system 20, including the humidity in the room 2, as absolute humidity. Details of the humidifier 16 will be described later.

[0036] The dust collection filter 17 is a dust collection filter that collects particles suspended in the air introduced into the air-conditioned room 18. The dust collection filter 17 collects particles contained in the air transported into the air-conditioned room 18 through the circulation port 6, thereby making the air supplied to the room by the transport fan 3 clean air. Here, the dust collection filter 17 is installed in the area between the air conditioner 13 and the humidifier 16 so as to block the air flow path.

[0037] The controller 50 is a controller that controls the entire air conditioning system 20. The controller 50 is connected to each of the heat exchange fan 4, the transport fan 3, the room damper 5, the room temperature sensor 11, the room humidity sensor 12, the air conditioner 13, the suction temperature sensor 14, the suction port damper 15, and the humidifier 16 so as to be able to communicate with them via wireless communication.

[0038] Furthermore, the controller 50 controls the air conditioner 13, humidifier 16, opening degree of the intake damper 15, the air volume of the transport fan 3, and the opening degree of the room damper 5, which serve as air conditioners, in accordance with the room temperature and room humidity of each room 2 acquired by the room temperature sensor 11 and the room humidity sensor 12, the set temperature (room set temperature) and set humidity (room set humidity) set for each room 2a to 2d, and the air temperature of the air-conditioned room 18 acquired by the intake temperature sensor 14. The air volume of the transport fan 3 may be controlled individually for each fan.

[0039] As a result, the air conditioned in the air-conditioning room 18 is transported to each room 2 at the air volume set in each transport fan 3 and each room damper 5. Therefore, the room temperature and room humidity of each room 2 are controlled to be the room set temperature and room set humidity.

[0040] Here, the controller 50 is connected by wireless communication with the heat exchange fan 4, the transport fan 3, the room damper 5, the room temperature sensor 11, the room humidity sensor 12, the air conditioner 13, the suction temperature sensor 14, the suction port damper 15, and the humidifier 16, thereby making it possible to eliminate the need for complicated wiring work. However, all of these, or some of these and the controller 50 may be configured to be able to communicate with each other by wired communication.

[0041] Next, the configuration of the humidifier 16 will be described with reference to Fig. 2. Fig. 2 is a schematic cross-sectional view of the humidifier 16 that constitutes the air conditioning system 20.

[0042] 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 and finely disperse water pumped by the rotation of the water lift pipe 37, and to include the water in air whose temperature has been adjusted by the air conditioner 13 and release it.

[0043] The humidifier 16 includes an intake port 31 for drawing in air from the air-conditioning chamber 18, an exhaust port 32 for blowing out humidified air into the air-conditioning chamber 18, an air passage provided between the intake port 31 and the exhaust port 32, and a liquid atomization chamber 33 provided in this air passage.

[0044] The suction port 31 is provided on the top surface of a housing that constitutes the outer frame of the humidifier 16, and the outlet port 32 is provided on the side surface of the housing. The liquid atomization chamber 33 is the main part of the humidifier 16, and is where water is atomized by a centrifugal water crushing method. The suction port 31 is equipped with a suction port damper 15 as shown in FIG. 1.

[0045] Specifically, the humidifier 16 includes a rotary motor 34, a rotary shaft 35 rotated by the rotary motor 34, a centrifugal fan 36, a cylindrical lifting pipe 37, a water storage section 40, a first eliminator 41, and a second eliminator 42.

[0046] The water lift pipe 37 is fixed to the rotating shaft 35 inside the liquid atomization chamber 33, and while rotating in accordance with the rotation of the rotating shaft 35, it pumps up water from a circular water lift port provided vertically downward. More specifically, the water lift pipe 37 has an inverted cone-shaped hollow structure, and has a circular water lift port provided vertically downward, and the rotating shaft 35 is fixed vertically to the center of the top surface of the inverted cone above the water lift pipe 37. The rotating shaft 35 is connected to the rotating motor 34 located vertically above the liquid atomization chamber 33, so that the rotational motion of the rotating motor 34 is transmitted to the water lift pipe 37 through the rotating shaft 35, causing the water lift pipe 37 to rotate.

[0047] The rise pipe 37 is provided with a plurality of rotating plates 38 formed on the top surface side of the inverted cone shape so as to protrude outward from the outer surface of the rise pipe 37. The plurality of rotating plates 38 are formed so as to protrude outward from the outer surface of the rise pipe 37 with a predetermined interval in the axial direction of the rotating shaft 35 between the upper and lower adjacent rotating plates 38. Since the rotating plates 38 rotate together with the rise pipe 37, it is preferable that the rotating plates 38 have 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 rise pipe 37.

[0048] Further, a plurality of openings 39 penetrating the wall surface of the rise pipe 37 are provided on the wall surface of the rise pipe 37. Each of the plurality of openings 39 is provided at a position that communicates the inside of the rise pipe 37 with the upper surface of a rotating plate 38 formed so as to protrude outward from the outer surface of the rise pipe 37.

[0049] The centrifugal fan 36 is disposed vertically above the water lift pipe 37, and serves to take air into the device from the air conditioning room 18. The centrifugal fan 36 is fixed to the rotating shaft 35, like the water lift pipe 37, and rotates in accordance with the rotation of the rotating shaft 35 to introduce air into the liquid atomization chamber 33. The flow rate of the air introduced into the humidifier 16 (air introduced into the liquid atomization chamber 33) increases or decreases depending on the air volume of the transport fan 3.

[0050] The water storage section 40 is located vertically below the rise pipe 37 and stores the water that the rise pipe 37 pumps from the rise port. The depth of the water storage section 40 is designed so that a part of the lower part of the rise pipe 37, for example, a length of about one-third to one-hundredth of the cone height of the rise pipe 37, is submerged. This depth can be designed according to the required amount of water to be pumped. The bottom surface of the water storage section 40 is formed in a cone shape facing the rise port. Water is supplied to the water storage section 40 by a water supply section (not shown).

[0051] The first eliminator 41 is a porous body through which air can pass, and is provided on the side (outer periphery in the centrifugal direction) of the liquid atomization chamber 33 so that air can pass therethrough in the centrifugal direction. The first eliminator 41 atomizes the water droplets discharged from the opening 39 of the water lift pipe 37 by collision with the first eliminator 41, and collects the water droplets contained in the air passing through the liquid atomization chamber 33. As a result, the air flowing through the humidifier 16 contains only vaporized water.

[0052] The second eliminator 42 is provided downstream of the first eliminator 41 and is arranged so that air flows vertically upward. The first eliminator 41 is also a porous body through which air can flow, and collects water droplets from the water contained in the air passing through the first eliminator 41 by collision with the first eliminator 41. In this way, the fine water droplets are doubly collected by the two eliminators, and large water droplets can be collected more accurately.

[0053] Next, the operating principle of humidification (water atomization) in the humidifier 16 will be described.

[0054] Next, the operational principle of humidification (dispersion of water into fine particles) in the humidifier 16 will be described with reference to Fig. 2. In Fig. 2, the flow of air and the flow of water within the device are respectively indicated by arrows.

[0055] First, when the operation of the humidifier 16 is started, the rotary motor 34 rotates the rotary shaft 35 at a first rotation speed, and the centrifugal fan 36 starts sucking air from the air-conditioning room 18 through the suction port 31. Then, the lift pipe 37 rotates in accordance with the rotation of the rotary shaft 35 at the first rotation speed. Then, as shown by the water flow indicated by the dashed arrow, the water stored in the water storage section 40 is pumped up by the lift pipe 37 due to the centrifugal force generated by the rotation. Here, the first rotation speed of the rotary motor 34 (lift pipe 37) is set between 500 rpm and 3000 rpm depending on the air blowing volume and the amount of humidification of the air, for example. Since the lift pipe 37 has an inverted cone-shaped hollow structure, the water pumped up by the rotation is pumped up along the inner wall of the lift pipe 37. The pumped water is then discharged in the centrifugal direction from the opening 39 of the pumping pipe 37 along the rotating plate 38 and scattered as water droplets.

[0056] The water droplets scattered from the rotating plate 38 fly in the space surrounded by the first eliminator 41 (liquid atomization chamber 33), collide with the first eliminator 41, and are atomized. Meanwhile, the air passing through the liquid atomization chamber 33 moves to the outer periphery of the first eliminator 41 while containing the water crushed (atomized) by the first eliminator 41, as shown by the air flow indicated by the solid arrow. Then, in the process of the air flowing through the air passage from the first eliminator 41 to the second eliminator 42, an air vortex is generated, and the water and the air are mixed. Then, the air containing the water passes through the second eliminator 42. As a result, the humidifier 16 can humidify the air sucked in from the suction port 31 and blow out the humidified air from the blowout port 32.

[0057] The liquid to be atomized may be other than water, for example, hypochlorous acid water or other liquid having bactericidal or deodorizing properties.

[0058] Next, the controller 50 in the air conditioning system 20 will be described with reference to Fig. 3. Fig. 3 is a functional block diagram of the controller 50 in the air conditioning system 20.

[0059] The controller 50 is installed on a wall in a room such as a living room of the general house 1, which is the main space used for daily life, and controls the operation of the air conditioner 13, the transport fan 3, the room damper 5, the intake damper 15, and the humidifier 16. To facilitate operation by the user, the controller 50 is installed at a height about the same as a person's face from the floor of the room. The controller 50 has a rectangular shape and includes a display panel 50j in the center area on the front side of the main body and an operation panel 50a in the area to the right of the display panel 50j.

[0060] The display panel 50j is an LCD monitor or the like, and displays on the display screen the operating status of the air conditioner 13, the conveying fan 3, the room damper 5, the intake damper 15, and the humidifier 16, the room set temperature, the room set humidity, the current room temperature and room humidity in room 2, etc.

[0061] The operation panel 50a is a button switch or the like that allows the user to input the room set temperature, room set humidity, and the like for the room 2.

[0062] The controller 50 includes a control unit housed within its main body, the control unit having a computer CPU (Central Processing Unit), memory, and the like.

[0063] Specifically, the control unit of the controller 50 includes an input section 50b, a processing section 50c, a memory section 50d, a timing section 50e, a damper opening determination section 50f, an air volume determination section 50g, a set temperature determination section 50h, a rotation speed determination section 50k, and an output section 50i.

[0064] Input unit 50b receives information (first information) relating to the room temperature in room 2 from room temperature sensor 11, information (second information) relating to the room humidity in room 2 from room humidity sensor 12, information (third information) relating to the suction temperature of humidifier 16 from suction temperature sensor 14, and information (fourth information) relating to the user's input settings from operation panel 50a. Input unit 50b outputs the received first to fourth information to processing unit 50c.

[0065] The storage unit 50d stores data to be referenced or updated by the processing unit 50c. For example, the storage unit 50d stores an algorithm for determining the operation modes of the air conditioner 13, the humidifier 16, and the transport fan 3. The storage unit 50d also stores the first information to the fourth information received by the input unit 50b in chronological order. The storage unit 50d outputs the stored data (stored data) to the processing unit 50c in response to a request from the processing unit 50c.

[0066] The timekeeping unit 50e is used to measure time as necessary in the programs executed by the processing unit 50c, and outputs data indicating the current time (time data) to the processing unit 50c.

[0067] The processing unit 50c receives the first information to the fourth information from the input unit 50b, the stored data from the memory unit 50d, and the time data from the clock unit 50e. The processing unit 50c uses each piece of received information to identify the requested air conditioning amount and requested humidification amount required for the room 2 at regular intervals (e.g., 5 minutes). More specifically, the processing unit 50c identifies the requested air conditioning amount required individually for each of the rooms 2a to 2d at regular intervals based on the time data acquired from the clock unit 50e and the temperature difference between the room set temperature stored in the memory unit 50d and the room temperature detected by the room temperature sensors 11a to 11d installed in the rooms 2a to 2d. Similarly, the processing unit 50c determines the required amount of humidification required for each of the rooms 2a-2d based on the humidity difference between the room set humidity stored in the memory unit 50d and the room humidity detected by the room humidity sensors 12a-12d installed in the rooms 2a-2d at regular time intervals based on the time data obtained from the timer unit 50e. In addition, the processing unit 50c updates the display on the display panel 50j via the output unit 50i in response to changes in the information displayed on the display panel 50j.

[0068] The damper opening specifying unit 50f acquires information relating to the required air conditioning amount from the processing unit 50c, and specifies the opening degree of the room dampers 5a-5d based on the ratio of the required air conditioning amount for each of the rooms 2a-2d. Furthermore, as will be described in detail later, the damper opening specifying unit 50f specifies the opening degree of the inlet damper 15 in accordance with the air blowing control operation of the transport fan 3. The damper opening specifying unit 50f then outputs information (opening degree information) relating to the specified opening degrees of the room dampers 5a-5d and the opening degree of the inlet damper 15 to the processing unit 50c.

[0069] The air volume specifying unit 50g acquires information on the requested air conditioning volume from the processing unit 50c, and specifies the blowing air volume of the air conditioner 13 based on the average value or total value of the requested air conditioning volumes. The air volume specifying unit 50g also specifies the airflow volumes of the transport fans 3 (transport fans 3a and 3b) based on the average value or total value of the requested air conditioning volumes for the first floor and the second floor. The air volume specifying unit 50g then outputs information on the specified blowing air volume of the air conditioner 13 (blowout air volume information) and information on the specified airflow volume of the transport fan 3 (airflow volume information) to the processing unit 50c.

[0070] The set temperature specifying unit 50h acquires information about the requested air conditioning amount from the processing unit 50c, and specifies the set temperature of the air conditioner 13 based on the average value or total value of the requested air conditioning amount. Then, the set temperature specifying unit 50h outputs information about the specified set temperature of the air conditioner 13 (air conditioner set temperature information) to the processing unit 50c.

[0071] The rotation speed determination unit 50k acquires information on the required air conditioning amount, information on the suction temperature of the humidifier 16, and air flow amount information from the processing unit 50c, and determines the rotation speed of the lift pipe 37 (rotary motor 34) of the humidifier 16. Then, the rotation speed determination unit 50k outputs information on the determined rotation speed of the lift pipe 37 (rotary speed information) to the processing unit 50c.

[0072] The processing unit 50c receives opening information from the damper opening degree specifying unit 50f, blowing air volume information and blowing air volume information from the air volume specifying unit 50g, air conditioner set temperature information from the set temperature specifying unit 50h, and rotation speed information from the rotation speed specifying unit 50k. Using each piece of received information, the processing unit 50c specifies control information related to the operation of each of the air conditioner 13, the transport fan 3 (transport fan 3a, transport fan 3b), the room damper 5 (room dampers 5a to 5d), the air inlet damper 15, and the humidifier 16. Then, the processing unit 50c outputs the specified control information to the output unit 50i.

[0073] The output unit 50i outputs the control information received from the processing unit 50c to the air conditioner 13, the transport fan 3 (transport fan 3a, transport fan 3b), the room damper 5 (room dampers 5a to 5d), the air inlet damper 15, and the humidifier 16.

[0074] The air conditioner 13 performs an air conditioning operation at the air conditioning set temperature and blowing air volume based on the control information output from the output unit 50i. The transport fan 3 (transport fan 3a, transport fan 3b) performs an air blowing operation at the respective air blowing volumes based on the control information ....

[0075] In the manner described above, the controller 50 causes the air conditioner 13, the transport fan 3, the room damper 5, the air inlet damper 15, and the humidifier 16 to each operate.

[0076] Next, the basic operation of the controller 50 will be described with reference to Fig. 4. Fig. 4 is a flow chart showing the basic processing operation of the controller 50.

[0077] First, the controller 50 performs a determination as to whether the air conditioning system 20 should be terminated (step S01). As a result, if the power supply of the air conditioning system 20 is 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 is terminated. On the other hand, if the power supply of the air conditioning system 20 is on (NO in step S01), a determination as to whether time has passed is performed (step S02). As a result, if the controller 50 determines that a certain time (e.g., 10 minutes) has not passed since the previous process (NO in step S02), it returns to step S01. On the other hand, if a certain time has passed since the previous process (YES in step S02), it proceeds to step S03, where it performs output specification processing for the room damper 5, the air conditioner 13, and the transport fan 3.

[0078] First, the controller 50 starts a loop equal to the number of rooms 2 (step S03). Then, the controller 50 calculates the required air conditioning amount for each of the rooms 2a-2d (step S04). The controller 50 also specifies the opening degrees of the room dampers 5a-5d corresponding to each of the rooms 2a-2d (step S05). Then, the controller 50 ends the loop when the calculation of the required air conditioning amount and the specification of the opening degrees of the room dampers 5a-5d for all of the rooms 2 are completed (step S06).

[0079] The processing in the loop of steps S03 to S06 will be described in more detail using the living room 2a as an example.

[0080] In step S04, the controller 50 determines the requested air conditioning amount for room 2a as the temperature difference between the room temperature acquired from the room temperature sensor 11a and the room set temperature set for room 2a. More specifically, the requested air conditioning amount is determined based on the value obtained by subtracting the room temperature from the room set temperature during heating operation, and is determined based on the value obtained by subtracting the room temperature from the room set temperature during cooling operation. This means that the larger the requested air conditioning amount is as a positive value, the more air conditioning is required in room 2a.

[0081] In step S05, the opening degree of the room damper 5a corresponding to the room 2a is specified according to the required air conditioning amount of the room 2a. In this embodiment, when the required air conditioning amount is 2° C. or more, the opening degree is "100%", when it is 1° C. or more and less than 2° C., the opening degree is "60%," when it is 0° C. or more and less than 1° C., the opening degree is "45%," when it is -1° C. or more and less than 0° C., the opening degree is "50%," and when it is less than -1° C., the opening degree is "10%". By setting in this manner, the opening degrees of the room dampers 5a to 5d are set according to the ratio of the required air conditioning amounts of the rooms 2a to 2d, and more conditioned air is blown to the room (room 2) that requires a higher air conditioning amount, making it possible to control the temperature for each room 2.

[0082] Next, the controller 50 calculates the overall required air conditioning amount for the general residence 1 based on the required air conditioning amounts for each of the rooms 2 (step S07). In this embodiment, the required air conditioning amount for the general residence 1 is calculated based on the average value of the required air conditioning amounts for each of the rooms 2.

[0083] Next, the controller 50 specifies the air conditioning set temperature and the blowing 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 increases the air conditioning set temperature in heating operation as the required air conditioning volume increases, and decreases the air conditioning set temperature in cooling operation as the required air conditioning volume increases. For example, when the required air conditioning volume 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 when the required air conditioning volume is 0°C or more and less than 1°C, the controller 50 sets the air conditioning set temperature 1 degree higher than the room set temperature of the living room 2 in heating operation and 1 degree lower than the room set temperature of the living room 2 in cooling operation. Also, when the required air conditioning volume is 1°C or more, the controller 50 sets the air conditioning set temperature 2 degrees higher than the room set temperature of the living room 2 in heating operation and 2 degrees lower than the room set temperature of the living room 2 in cooling operation. As a result, the higher the requested air conditioning amount is, the higher the output of air conditioner 13 will be operated, and the room temperature in room 2 will be controlled to the room set temperature more quickly.

[0084] Furthermore, the controller 50 controls the blowing air volume of the air conditioner 13 to be larger as the required air conditioning volume increases. In this embodiment, when the required air conditioning volume is less than 0° C., the blowing air volume is set to 500 m 3 / h, and when the required air conditioning volume is 0℃ or more but less than 1℃, the blowing volume is 700m 3 / h, and when the required air conditioning volume is 2°C or more, the blowing air volume is 1200 m 3 / h.

[0085] Next, the controller 50 specifies the total air volume of the transport fan 3 to be equal to or slightly larger than the blowing air volume of the air conditioner 13 (step S09). In other words, the controller 50 specifies the air volume difference between the total air volume of the transport fan 3 and the blowing air volume of the air conditioner 13 to be equal to or smaller than the reference air volume. In this way, the controller 50 suppresses the power consumption of the transport fan 3.

[0086] 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 for the rooms 2 on the first and second floors is set as the required air conditioning amount for that floor.

[0087] Next, the airflow volume of the transport fan 3 is specified based on the required air conditioning volume calculated in step S10 (step S11). The controller 50 specifies the airflow volumes of the transport fans 3 for the first and second floors so as to provide an airflow ratio according to the ratio of the required air conditioning volumes. Specifically, the controller 50 determines that the required air conditioning volume for the second floor is 1°C, the required air conditioning volume for the first floor is 2°C, and the total airflow volume of the transport fans 3 specified in step S09 is 1200 m 3 / h, the air volume ratio between the transport fans 3 is 1:2, and the air volume of the transport fan 3a on the second floor is 400 m 3 / h, the air volume of the conveying fan 3b on the first floor is 800 m 3 / h. In this way, even if there is a difference in the required air conditioning volume between the first floor and the second floor, by making a difference in the airflow volume of the transport fan 3, the amount of transported heat will be different, and it is possible to transport an amount of heat that matches the required air conditioning volume on both the first and second floors.

[0088] Next, the controller 50 starts the humidification control (step S12).

[0089] Next, the humidification control will be described with reference to Fig. 5 and Fig. 6. Fig. 5 is a flow chart showing the humidification control operation of the controller. Fig. 6 is a diagram showing data on the humidification performance of the humidifier 16.

[0090] When humidification control is started, the controller 50 starts a loop for the number of rooms 2 that are the conditioned spaces (step S21). The controller 50 then calculates the required amount of humidification for each of the rooms 2a to 2d (step S22). The controller 50 then ends the loop when calculation of the required amount of humidification for all of the rooms 2 is completed (step S23).

[0091] The processing in the loop of steps S21 to S23 will be described in more detail using the living room 2a as an example.

[0092] In step S22, the controller 50 determines the required humidification amount for the living room 2a as the humidity difference between the living room humidity acquired from the living room humidity sensor 12a and the room set humidity set for the living room 2a. In detail, the living room set humidity and the living room humidity are each converted to absolute humidity, and the required humidification amount is determined by subtracting the living room absolute humidity from the living room set absolute humidity. This means that the greater the required humidification amount is as a positive value, the more humidification is required for the living room 2a.

[0093] Next, the controller 50 calculates the overall required humidification amount for the general residence 1 based on the required humidification amounts for each of the living rooms 2 (step S24). In this embodiment, the required air conditioning amount for the general residence 1 is calculated based on the average value of the required humidification amounts for each of the living rooms 2.

[0094] Next, the controller 50 performs an operation determination of the humidifier 16 (step S25). In detail, if the requested humidification amount of the general residence 1 is positive (YES in step S25), the humidifier 16 is operated and the process proceeds to step S26. If the requested humidification amount of the general residence 1 is 0 or negative (NO in step S25), the rotation speed of the water lift pipe 37 is set to "0" and the humidifier 16 is not operated (step S28), and the humidification control ends.

[0095] Next, the controller 50 specifies the required rotation speed of the water lift pipe 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 transport fan 3 (step S26). In this step S26, the controller 50 sets the required rotation speed to be larger as the required humidification amount is higher, the suction temperature is lower, or the total air volume of the transport fan 3 is smaller.

[0096] In this embodiment, the controller 50 specifies the required rotational speed based on the humidifying performance data of the humidifying device 16 shown in FIG. 6. The humidifying performance data is data obtained in advance through experiments, and it shows the humidifying amount X output by the humidifying device 16 when it operates under the conditions of the suction temperature T, the rotational speed R of the lift pipe 37, and the total air volume Q of the transport fan 3. Here, the humidifying amount X output by the humidifying device 16 corresponds to the amount of moisture contained in the air flowing through the humidifying device 16. From the characteristics of the humidifying device 16, the suction temperature T, the rotational speed R, and the total air volume Q each have a positive correlation with the humidifying amount X. For example, when the total air volumes Q1 and Q2 have the relationship Q1 < Q2, and assuming the temperature is T1 and the rotational speed is R1, the magnitude relationship between the humidifying amounts X1 and X2 is X1 < X2.

[0097] Subsequently, the details of the method for specifying the required rotational speed from the humidifying performance data will be described. First, a regression equation regarding the humidifying amount X is created from the table data to obtain Equation (1) in FIG. 6. Next, the created regression equation is transformed so that the rotational speed R comes to the left side to obtain Equation (2) in FIG. 6. Then, the required rotational speed is calculated by substituting the suction temperature T from the suction temperature sensor 14 for the suction temperature, the total air volume Q of the transport fan 3 for the total air volume, and the required humidifying amount X' of the general house 1 for the humidifying amount X into the right side of Equation (2). Note that the regression equation of Equation (1) is a combination of the first-order terms of the rotational speed R, the suction temperature T, and the total air volume Q, but in order to improve the accuracy of the regression, terms of the second order or higher of any of the rotational speed R, the suction temperature T, and the total air volume Q may be included.

[0098] Subsequently, when the required rotational speed exceeds the preset upper limit rotational speed, the controller 50 specifies the upper limit rotational speed as the rotational speed of the lift pipe 37, and when the required rotational speed is lower than the preset lower limit rotational speed, the controller 50 specifies the lower limit rotational speed as the rotational speed of the lift pipe 37 (step S27).

[0099] As a result, when the total air volume Q of the transport fan 3 increases while the required humidification amount X' and the suction temperature T are constant, the rotation speed R of the lift pipe 37 is controlled to decrease, so that the amount of humidification added to the air transported to each room 2 decreases. Similarly, when the required humidification amount X' and the suction temperature T are constant, the rotation speed R of the lift pipe 37 is controlled to increase, so that the amount of humidification added to the air transported to each room 2 increases. In other words, even if the total air volume Q of the transport fan 3 fluctuates and the amount of air transported to each room 2 fluctuates, the amount of humidification added to the air transported to each room 2 is adjusted in accordance with the fluctuation in the total air volume Q of the transport fan 3, so that the fluctuation in the amount of moisture supplied to each classroom 2 is suppressed.

[0100] 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 amount of humidification, and if the required rotation speed is below the lower limit rotation speed, it means that the amount of humidification that can be output at the lower limit rotation speed is excessive for the required amount of humidification.

[0101] Next, a method for resolving the excess or deficiency of the amount of humidification by adjusting the total air volume Q of the transport fan 3 or the opening degree of the suction port damper 15 in these cases will be described.

[0102] First, a process for correcting the airflow rate of the transport fan 3 in humidification control will be described with reference to Fig. 7. Fig. 7 is a flow chart showing the process for correcting the airflow rate of the transport fan by the controller 50.

[0103] 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 by a predetermined ratio (for example, 1.1 times) (step S32). When 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). When the required rotation speed is lower than the lower limit rotation speed (YES in step S33), the controller 50 decreases the total air volume Q of the transport fan 3 by a predetermined ratio (for example, 0.9 times) (step S34). In this embodiment, the total air volume Q of the transport fan 3 is set to be equal to the blown air volume of the air conditioner 13, so that the blown air volume of the air conditioner 13 is increased or decreased so as to be equal to the total air volume of the transport fan 3 in accordance with the air volume correction of the transport fan 3. By doing so, the inflow air volume to 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 lower than the requested amount of humidification, the amount of air transported to each room 2 increases. Also, when the amount of humidification that can be output at the lower limit rotation speed is higher than the requested amount of humidification, the amount of air transported to each room 2 decreases. Note that the total air volume Q of the transport fan 3 after correction may be determined by solving equation (1) for the total air volume Q and substituting the humidification amount X as the requested amount of humidification for the general house 1, the rotation speed R as the upper limit rotation speed, and the suction temperature T as the suction temperature from the suction temperature sensor 14.

[0104] Next, the control of the suction port damper 15 will be described with reference to Fig. 8. Fig. 8 is a flowchart showing the suction port damper control operation of the controller 50.

[0105] First, the controller 50 judges whether the required rotation speed is below the lower limit rotation speed (step S41). If the required rotation speed is below the lower limit rotation speed (YES in step S41), the opening degree of the suction port damper 15 is reduced, for example, to "50%" (step S42) to reduce the amount of air flowing into the humidifier 16. On the other hand, if the required rotation speed is equal to or higher than the lower limit rotation speed (NO in step S41), the opening degree of the suction port damper 15 is set to "100%" (step S43) so as not to obstruct the air flowing into the humidifier 16. As a result, when the required rotation speed is below the lower limit rotation speed, the opening degree of the suction port damper 15 is reduced, thereby reducing the amount of air flowing into the humidifier 16 and further reducing the amount of humidification to be added to the air to be transported to each room 2.

[0106] As described above, according to the air conditioning system 20 according to the first embodiment, the following effects can be obtained.

[0107] (1) The air conditioning system 20 includes an air-conditioned room 18 configured to be able to introduce air from the outside, an air conditioner 13 installed in the air-conditioned room 18 to adjust the temperature of the air in the air-conditioned room 18, a humidifier 16 installed in the air-conditioned room 18 to humidify the air whose temperature has been adjusted by the air conditioner 13, a plurality of transport fans 3 that transport the air in the air-conditioned room 18 to a plurality of rooms 2 independent of the air-conditioned room 18, and a controller 50 that controls the humidifier 16 and the transport fan 3. The humidifier 16 is configured to centrifugally crush and finely atomize water pumped by the rotation of a lift pipe 37, and release the water by incorporating it into the air whose temperature has been adjusted by the air conditioner 13. The controller 50 determines the rotation speed of the water lift pipe 37 (rotary motor 34) based on the required humidification amount for the room 2, the temperature of the air temperature-adjusted by the air conditioner 13, and the air volume of the conveying fan 3, and controls the amount of humidification to the air temperature-adjusted by the air conditioner 13 according to the determined rotation speed.

[0108] As a result, even if the volume of air transported to each room 2 fluctuates, the volume of humidification added to the air transported to each room 2 is adjusted accordingly, suppressing fluctuations in the amount of moisture supplied to each classroom 2 and enabling the humidity of the air in each room 2 to be stably maintained at a target humidity. In other words, an air conditioning system 20 can be provided that is capable of controlling humidification by the humidifier 16 in response to fluctuations in the air volume of the transport fan 3.

[0109] (2) In the air conditioning system 20, the controller 50 controls the rotation speed of the water lift pipe 37 to decrease when the air volume of the transport fan 3 increases, and controls the rotation speed of the water lift pipe 37 to increase when the air volume of the transport fan 3 decreases. As a result, when the air volume of the transport fan 3 increases, the amount of humidification added to the air transported to each room 2 decreases, and when the air volume of the transport fan 3 decreases, the amount of humidification added to the air transported to each room 2 increases, so that fluctuations in the amount of moisture supplied to each room 2 due to fluctuations in the air volume of the transport fan 3 can be reliably suppressed.

[0110] (3) In the air conditioning system 20, the water pump pipe 37 can rotate within a range between the lower limit rotation speed and the upper limit rotation speed, and the controller 50 controls the conveying fan 3 to increase the air volume when the humidification amount that can be output at the upper limit rotation speed is lower than the required humidification amount, and controls the conveying fan 3 to decrease the air volume when the humidification amount that can be output at the lower limit rotation speed is higher than the required humidification amount. As a result, when the humidification amount that can be output at the upper limit rotation speed is lower than the required humidification amount, the conveying amount of air conveyed to each room 2 increases, so that the amount of moisture supplied to each room 2 can be increased. On the other hand, when the humidification amount that can be output at the lower limit rotation speed is higher than the required humidification amount, the conveying amount of air conveyed to each room 2 decreases, so that the amount of moisture supplied to each room 2 can be reduced. In other words, in the air conditioning system 20, the range in which the humidification amount can be adjusted by the humidifier 16 is widened, and highly accurate humidification adjustment is possible for the air whose temperature has been adjusted by the air conditioner 13.

[0111] (4) Air conditioning system 20 further includes suction inlet damper 15 that adjusts the amount of air flowing into humidifier 16, and controller 50 is configured to be able to control suction inlet damper 15, and when the amount of humidification that can be output at the lower limit rotation speed exceeds the requested amount of humidification, control is performed to reduce the amount of air flowing into suction inlet damper 15. As a result, when the amount of humidification that can be output at the lower limit rotation speed exceeds the requested amount of humidification, the amount of humidification to be added to the air conveyed to each room 2 is further reduced, and the amount of moisture supplied to each room 2 can be further reduced.

[0112] The present invention has been described above based on the embodiments. These embodiments are merely examples, and it will be understood by those skilled in the art that various modifications are possible in the combination of each component or each treatment process, and that such modifications are also within the scope of the present invention.
