Description

[Technical Field]

[0001] The present invention relates to an air conditioning system for conditioning a plurality of spaces. [Background technology]

[0002] Traditionally, homes have been air-conditioned using central air conditioners. However, with the growing demand for energy-efficient homes and stricter regulations, it is predicted 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 is a whole-building air conditioning system, which conditions air transported from multiple spaces (living rooms) to an air-conditioning room to a predetermined temperature and humidity level within the air-conditioning room, and then transports the air to each of the multiple spaces (living rooms) so that the air temperature and humidity in the multiple spaces reach target temperature and humidity levels (see, for example, Patent Document 1).

[0004] On the other hand, there is a humidifying and purifying device that generates hypochlorous acid water, centrifugally crushes it, humidifies it, and vaporizes it, thereby adding hypochlorous acid to the air as a purifying component. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2020-63899 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in conventional air conditioning systems using a humidifying and purifying device, there is a problem that the amount of hypochlorous acid supplied from the humidifying and purifying device varies depending on the airflow rate of the air conditioning system linked to the temperature control during cooling operation. For this reason, air conditioning systems using a humidifying and purifying device are required to improve the controllability of the supply amount of hypochlorous acid relative to the target supply amount.

[0007] SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned conventional problems, and has an object to provide an air conditioning system that can improve the controllability of the amount of air purifying component supplied during cooling operation. [Means for solving the problem]

[0008] In order to solve the above problems, the air conditioning system of the present invention includes an air-conditioned room configured to be able to introduce air from a living space, an air conditioner installed in the air-conditioned room and adjusting the temperature of the air in the air-conditioned room, a humidifying and purifying device installed in the air-conditioned room and adding an air purifying component to the air adjusted in temperature by the air conditioner while performing a humidifying operation, a blower installed in the air-conditioned room and transporting the air that has circulated through the humidifying and purifying device to the living space, and a control unit that controls the blowing operation of the blower. a temperature sensor that acquires the temperature of the air in the living space as the living room temperature; The control unit performs air conditioning control for the living space by switching between a first air volume control mode in which the air conditioner controls the air volume of the blower based on a temperature adjustment operation in which the air temperature of the living space is adjusted to a target temperature, and a second air volume control mode in which the humidifying and purifying device controls the air volume of the blower based on a humidifying and purifying operation in which the air in the living space is adjusted to a target air purity level. When the temperature difference between the room temperature acquired by the temperature sensor and the set temperature of the air conditioner is equal to or greater than a reference temperature difference, the fan is operated in a first air volume control mode, and when the temperature difference is less than the reference temperature difference, the fan is operated in a second air volume control mode. It is characterized by: [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0011] The air conditioning system of the present invention includes an air-conditioned room configured to be able to introduce air from a living space, an air conditioner installed in the air-conditioned room and regulating the temperature of the air in the air-conditioned room, a humidifying and purifying device installed in the air-conditioned room and applying an air purifying component while humidifying the air temperature-regulated by the air conditioner, a blower installed in the air-conditioned room and transporting the air that has circulated through the humidifying and purifying device to a living space, and a control unit that controls the blowing operation of the blower.The control unit performs air conditioning control for the living space by switching between a first air volume control mode in which the air conditioner controls the air volume of the blower based on the temperature regulation operation of the air conditioner to regulate the temperature of the air in the living space to a target temperature, and a second air volume control mode in which the humidifying and purifying device controls the air volume of the blower based on the humidifying and purifying operation of the humidifying and purifying device to bring the air in the living space to a target air purity level.

[0012] According to this configuration, during cooling operation, which is a temperature control operation in which the amount of air purification component supplied to the living space is likely to be insufficient, the air volume of the blower is controlled by switching between the first air volume control mode and the second air volume control mode to supply the air purification component to the living space, thereby making it possible to stably supply the air purification component so that the living space achieves the target air purification level. In other words, the air conditioning system can improve the controllability of the air purification component supply amount during cooling operation.

[0013] The air conditioning system according to the present invention also includes a temperature sensor that acquires the temperature of air in a living space as a living room temperature. The control unit preferably controls the blower to operate in a first air volume control mode when a temperature difference between the living room temperature acquired by the temperature sensor and a set temperature of the air conditioner is equal to or greater than a reference temperature difference, and controls the blower to operate in a second air volume control mode when the temperature difference is less than the reference temperature difference. In this manner, when the temperature difference between the living room temperature and the set temperature is equal to or greater than the reference temperature difference, air conditioning control for the living room space is performed in the first air volume control mode with an air volume that prioritizes temperature adjustment. When the temperature difference becomes smaller, less than the reference temperature difference, and the temperature adjustment operation for the living room space is stabilized, air conditioning control for the living room space is performed with an air volume that prioritizes humidification and purification. This allows for a well-balanced adjustment of temperature adjustment and air purification for the living room space, and a stable supply of air purification components so that the living room space achieves a target air purification level.

[0014] Furthermore, in the air conditioning system according to the present invention, it is desirable that the control unit controls the air volume of the blower only in the first air volume control mode when the air conditioner is in heating operation, and controls the air volume of the blower by switching between the first air volume control mode and the second air volume control mode when the air conditioner is in cooling operation. By doing so, during heating operation, which is a temperature control operation that provides a high amount of humidification and makes it easy to supply an air purifying component to the living space, the first air volume control mode, which prioritizes temperature control as before, is maintained to supply the air purifying component to the living space so that the target air purity is achieved. During cooling operation, which is a temperature control operation that makes it difficult to supply the air purifying component to the living space, the control unit switches between the first air volume control mode and the second air volume control mode to supply the air purifying component to the living space so that the target air purity is achieved. This enables the air conditioning system to improve the controllability of the air purifying component supply amount during heating operation and cooling operation.

[0015] In the air conditioning system according to the present invention, the humidifying and purifying device preferably includes a centrifugal fan that introduces temperature-controlled air, the temperature of which has been controlled by the air conditioner, into the interior, and a humidifying section that impregnates the temperature-controlled air introduced by the centrifugal fan with water atomized by centrifugal crushing and then releases the air. In this way, the humidifying and purifying device introduces air into the interior of the humidifying and purifying device using the centrifugal fan, so that the amount of ventilation flowing through the interior is less affected by the air flow rate of the blower, making it easier to adjust the amount of air purification component added to the temperature-controlled air in the air-conditioned room.

[0016] In the air conditioning system according to the present invention, the humidifying and purifying device preferably uses hypochlorous acid water to humidify the temperature-controlled air while adding hypochlorous acid as an air purifying component. This allows the hypochlorous acid water, which has a disinfecting effect, to be atomized in the humidifying section and supplied into the air-conditioned room, thereby enabling the purification of the living space with hypochlorous acid.

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the following embodiments are examples of specific embodiments of the present invention and do not limit the technical scope of the present invention.

[0018] (Embodiment 1) First, an air conditioning system 20 according to a first embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a schematic connection diagram of an air conditioning system 20 according to a first embodiment of the present invention.

[0019] 1, the air conditioning system 20 includes a heat exchange fan 4, a plurality of living room dampers 5 (living room dampers 5a, 5b, 5c, and 5d), a plurality of circulation ports 6 (circulation ports 6a, 6b, 6c, and 6d), a plurality of living room exhaust ports 7 (living room exhaust ports 7a, 7b, 7c, and 7d), a plurality of living room air supply ports 8 (living room air supply ports 8a, 8b, 8c, and 8d), an outdoor temperature sensor 16, an air conditioning unit 18, an input / output terminal 19, and a humidifying and purifying device control unit 60 (see FIG. 3). The air conditioning unit 18 also includes a plurality of transport fans 3 (transport fans 3a and 3b), an indoor temperature and humidity sensor 12, an air conditioner 13, an intake temperature and humidity sensor 14, a dust collection filter 17, and a humidifying and purifying device 40.

[0020] The air conditioning system 20 is installed in a general residence 1, which is an example of a building. The general residence 1 has multiple (four in this embodiment) living rooms 2 (living rooms 2a, 2b, 2c, and 2d), as well as at least one air-conditioned room 18a that is independent of the living rooms 2. Here, the general residence 1 (residence) is a dwelling provided as a place for residents to live private lives, and the living rooms 2 generally include a living room, dining room, bedroom, private room, and children's room. The living rooms 2 provided by the air conditioning system 20 may also include a toilet, bathroom, washroom, or dressing room. The living rooms 2 (living rooms 2a to 2d) correspond to the "living room space" in the claims.

[0021] Living room 2a is equipped with a circulation port 6a, a living room exhaust port 7a, a living room air intake port 8a, and an input / output terminal 19. Living room 2b is equipped with a circulation port 6b, a living room exhaust port 7b, and a living room air intake port 8b. Living room 2c is equipped with a circulation port 6c, a living room exhaust port 7c, and a living room air intake port 8c. Living room 2d is equipped with a circulation port 6d, a living room exhaust port 7d, and a living room air intake port 8d.

[0022] An air conditioning unit 18 is installed in the air-conditioned room 18a. The air conditioning unit 18 is configured to include a transport fan 3 (transport fans 3a and 3b), a room damper 5 (room dampers 5a, 5b, 5c, and 5d), an indoor temperature and humidity sensor 12, an air conditioner 13, an intake temperature and humidity sensor 14, a humidifying and purifying device 40, and a dust collecting filter 17. More specifically, the air conditioning unit 18 is arranged in the following order from the upstream side of the air flow path through the air-conditioned room 18a: the indoor temperature and humidity sensor 12, the air conditioner 13, the dust collecting filter 17, the intake temperature and humidity sensor 14, the humidifying and purifying device 40, the transport fan 3, and the room damper 5.

[0023] The air-conditioned room 18a refers to a space of a certain size that can control the air supplied to each living room 2, but it is not intended as a living space and does not generally refer to a room where residents stay.

[0024] Air is introduced into air-conditioned room 18a from the outside. In air-conditioned room 18a, air (indoor air) transported from each living room 2 through circulation port 6 is mixed with outside air (outdoor air) taken in by heat exchange fan 4 and heat-exchanged. The air in air-conditioned room 18a is controlled by air conditioning unit 18 (air conditioner 13 and humidifying and purifying device 40) installed in air-conditioned room 18a to adjust the temperature and add an air purifying component (hypochlorous acid) that also adjusts the humidity, generating air to be transported to each living room 2. The air processed by air-conditioning unit 18 is transported to each living room 2 as intake airflow 10 by transport fan 3.

[0025] The air from each room 2 is transported to air-conditioned room 18a through circulation port 6 as shown by circulation flow 9, and is also heat-exchanged through heat exchange fan 4 through room exhaust port 7 as shown by intake air flow 11 before being discharged outdoors. Air conditioning system 20 performs Class 1 ventilation by using heat exchange fan 4 to exhaust indoor air from each room 2 while taking in outdoor air into the room. The ventilation airflow of heat exchange fan 4 can be set in multiple stages, and the ventilation airflow is set to meet the required ventilation volume stipulated by law.

[0026] Heat exchange fan 4 is configured to have an intake fan (not shown) 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 heat-exchanged outside air to air-conditioned room 18a (air-conditioning unit 18).

[0027] The transport fan 3 is provided on a wall surface (bottom wall surface) of the air-conditioned room 18a. The transport fan 3 transports air processed by the air conditioning unit 18 (air that has passed through a humidifying and purifying device 40, described below) to the living room 2. In other words, the air processed by the air conditioning unit 18 is transported by the transport fan 3 from the living room air intake port 8 to the living room 2 via a transport duct. More specifically, the air processed by the air conditioning unit 18 is transported by the transport fan 3a to living rooms 2a and 2b, which are located on the first floor of the general house 1, and by the transport fan 3b to living rooms 2c and 2d, which are located on the second floor of the general house 1. The transport ducts connected to the living room air intake port 8 of each living room 2 are provided independently. Here, the transport fan 3 corresponds to the "blower" in the claims.

[0028] A portion of the air in each living room 2 (living rooms 2a to 2d) is transported to air-conditioned room 18a via a circulation duct through the corresponding circulation port 6 (circulation ports 6a to 6d). The circulation ducts connecting air-conditioned room 18a 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 form a single circulation duct, which is then connected to air-conditioned room 18a.

[0029] When air is transported from the transport fan 3 to each of the living rooms 2, the living room dampers 5 adjust the opening degree of the living room dampers 5 to adjust the amount of air sent to each of the living rooms 2. More specifically, the living room dampers 5a and 5b adjust the amount of air sent to the living rooms 2a and 2b located on the first floor, respectively. The living room dampers 5c and 5d adjust the amount of air sent to the living rooms 2c and 2d located on the second floor, respectively.

[0030] As described above, each room circulation port 6 (circulation ports 6a to 6d) is an opening for conveying indoor air from each room 2 (rooms 2a to 2d) to air-conditioned room 18a. Each room circulation port 6 draws in air from each room 2 as a circulation flow 9.

[0031] As described above, each living room exhaust outlet 7 (living room exhaust outlets 7a to 7d) is an opening for conveying indoor air from each living room 2 (living rooms 2a to 2d) to the heat exchange fan 4. Each living room exhaust outlet 7 draws in air from each living room 2 as intake air flow 11.

[0032] As described above, each living room air supply port 8 (living room air supply ports 8a-8d) is an opening for conveying air from air-conditioned room 18a to each living room 2 (living rooms 2a-2d). Each living room air supply port 8 blows out air from air-conditioned room 18a as intake airflow 10.

[0033] The indoor temperature and humidity sensor 12 is installed upstream of the air conditioning unit 18 and acquires the temperature and humidity (relative humidity) of air drawn in from the living room 2 (living rooms 2a to 2d) and flowing into the air-conditioned room 18a (air-conditioning unit 18). The temperature and humidity read by the indoor temperature and humidity sensor 12 are used for humidity control by the humidifying and purifying device control unit 60 as representative values ​​of the room temperature humidity.

[0034] The air conditioner 13 corresponds to an air conditioning device and controls the temperature of the air conditioning unit 18. The air conditioner 13 cools (cooling operation) or heats (heating operation) the air in the air-conditioned room 18a so that the temperature of the air in the air-conditioned room 18a becomes a set temperature (air-conditioned room target temperature). Here, the set temperature is set based on the result of calculating the required heat amount from the temperature difference between the target temperature (room target temperature) set by the user and the room temperature detected by the room temperature and humidity sensor 12. In this embodiment, the set temperature is set to a temperature at least lower than the target temperature during cooling operation and at least higher than the target temperature during heating operation in order to more quickly adjust the air temperature in each room 2 to the target temperature.

[0035] Dust collection filter 17 is a dust collection filter that captures particles floating in the air introduced into air-conditioned room 18a. Dust collection filter 17 captures particles contained in the air transported into air-conditioned room 18a through circulation port 6, thereby cleaning the air that is supplied indoors by transport fan 3. Here, dust collection filter 17 is installed in the area between air conditioner 13 and humidifying and purifying device 40 so as to block the air flow path.

[0036] The humidifying and purifying device 40 is located downstream of the air conditioner 13 in the air-conditioned room 18a. When the humidity of the air in each room 2 (room humidity) is lower than the target humidity (room target humidity) set by the user, the humidifying and purifying device 40 humidifies the air in the air-conditioned room 18a so that the humidity reaches the target humidity. The humidifying and purifying device 40 also adds hypochlorous acid as an air purifying component to the circulating air during humidification. Even when it is determined that humidification is unnecessary, the humidifying and purifying device 40 continues humidifying within a range that does not significantly impair humidity comfort in order to add hypochlorous acid to the circulating air. Note that the humidity values ​​used here are expressed as relative humidity, but may be converted to absolute humidity using a predetermined conversion process. In this case, it is preferable to treat the entire humidity in the air-conditioning system 20, including the humidity in the room 2, as absolute humidity. The configuration of the humidifying and purifying device 40 will be described in detail below.

[0037] The intake temperature and humidity sensor 14 is a sensor that acquires the temperature and humidity (relative humidity) of air whose temperature has been adjusted by the air conditioner 13 in the air conditioning unit 18, and transmits them to the humidifying and purifying device control unit 60. More specifically, the intake temperature and humidity sensor 14 is installed downstream of the air conditioner 13 in the air conditioning unit 18, and acquires the temperature and humidity of air drawn into the humidifying and purifying device 40, and transmits them to the humidifying and purifying device control unit 60.

[0038] The outdoor temperature sensor 16 is installed in a location where it can detect the temperature of the outside air of the general house 1 (for example, the outside air inlet of the heat exchange fan 4, the outdoor unit of the air conditioner 13, the exterior wall of the general house 1, etc.), acquires the outside air temperature, and transmits it to the humidifying and purifying device control unit 60.

[0039] The input / output terminal 19 is a terminal for inputting user input information (e.g., air volume, target temperature, target humidity, whether or not hypochlorous acid is added, target supply level of hypochlorous acid, heat exchange level of the heat exchange fan 4, etc.) related to the air conditioning system 20 (air conditioning unit 18), and is communicatively connected to the system controller 50 wirelessly or via a wired connection.

[0040] Next, an outline of the configuration of the humidifying and purifying device 40 will be described with reference to Fig. 2. Fig. 2 is a schematic diagram showing the configuration of the humidifying and purifying device 40. Note that in Fig. 2, the configuration of the humidifying and purifying device 40 is shown in functional blocks, but in reality, the humidifying and purifying device 40 is housed in a single housing, and piping and the like are connected to the housing.

[0041] The humidifying and purifying device 40 is a device for humidifying the air in the air-conditioning room 18a by centrifugal water crushing, and adding hypochlorous acid as an air purifying component.

[0042] Specifically, the humidifying and purifying device 40 includes a micronizing section 41, a hypochlorous acid water generating section 30, a hypochlorous acid water supplying section 38, and a water supplying section 48.

[0043] The atomization section 41 is configured to include a mixing tank 42, a centrifugal crushing unit 43, a water level sensor 44, and a purification air duct 49, and is a unit for humidifying the air flowing through the purification air duct 49. When humidifying, the atomization section 41 imparts hypochlorous acid as an air purifying component to the flowing air along with atomized water. The atomization section 41 can also be called a liquid atomization chamber or an air purification section. More specifically, the atomization section 41 atomizes the mixed water stored in the mixing tank 42 (hypochlorous acid water obtained by mixing the hypochlorous acid water from the hypochlorous acid water generation section 30 and the water from the water supply section 48 to dilute the water) by centrifugal crushing, and causes the mixed water to be contained in the air flowing through the purification air duct 49.

[0044] The mixing tank 42 is a tank that stores hypochlorous acid water in the micronization unit 41, and can also be called a water storage unit. In the mixing tank 42, hypochlorous acid water of a predetermined concentration supplied from the hypochlorous acid water supply unit 38 (described later) and water supplied from the water supply unit 48 (described later) are mixed in the tank, and mixed water consisting of diluted hypochlorous acid water is stored. In addition, although not particularly shown, a drain outlet is provided at the bottom of the mixing tank 42 for discharging the stored mixed water.

[0045] The centrifugal crushing unit 43 is composed of a water lifting pipe 43a, a centrifugal fan 43b, and a humidifying motor (not shown), and performs humidifying and purifying operations by rotating the water lifting pipe 43a and the centrifugal fan 43b using the humidifying motor. The centrifugal crushing unit 43 uses centrifugal force to suck up the mixed water (hypochlorous acid water) stored in the mixing tank 42 by rotating the water lifting pipe 43a, scattering, colliding, and crushing it in the surrounding area (centrifugal direction), thereby incorporating moisture and hypochlorous acid into the air. The air containing moisture and hypochlorous acid is then ventilated through the purification air duct 49 by the rotation of the centrifugal fan 43b and transported outside the humidifying and purifying device 40.

[0046] The water level sensor 44 detects the water level of the mixed water stored in the mixing tank 42 and outputs the result to the humidifying and purifying device control unit 60. More specifically, the water level sensor 44 has a water level sensor 44a that detects the water level of the mixed water stored in the mixing tank 42 when it is full, and a water level sensor 44b that detects the water level of the mixed water when it has decreased by a specified amount from the full state.

[0047] Here, the specified amount is set to the amount of mixed water diluted and mixed with water supplied from the water supply unit 48 to achieve a predetermined hypochlorous acid water concentration, relative to the amount of hypochlorous acid water that can be produced by one electrolysis in the electrolytic cell 33 of the hypochlorous acid water generation unit 30.

[0048] The purification air duct 49 is an air duct for adding moisture and hypochlorous acid to the air passing through the atomization section 41. An air intake and an air outlet (not shown) for the air passing through the purification air duct 49 are provided on the wall surface or the ceiling surface of the atomization section 41. The purification air duct 49 communicates with the inside of the air-conditioning room 18a.

[0049] The atomization unit 41 is configured with the above-mentioned components. In the atomization unit 41, the air drawn in from the air-conditioning room 18a by the rotation of the centrifugal fan 43b is added with moisture and hypochlorous acid by the rotation of the water lift pipe 43a, and the air is supplied to the air-conditioning room 18a.

[0050] The hypochlorous acid water generator 30 includes a salt water tank 31, a salt water transfer pump 32, an electrolytic cell 33, electrodes 34, and an electrolytic cell supply valve 35.

[0051] The saltwater tank 31 stores saltwater (aqueous sodium chloride solution) and supplies the saltwater to the electrolytic cell 33 via the saltwater transfer pump 32 in response to an output signal from the humidifying and purifying device control unit 60. The electrolytic cell 33 stores the saltwater to be electrolyzed, supplied from the saltwater tank 31. In response to an output signal from the humidifying and purifying device control unit 60, tap water is supplied to the electrolytic cell 33 from a water supply pipe 47 (described later) via an electrolytic cell supply valve 35, and the supplied tap water and saltwater are mixed to store saltwater of a predetermined concentration. The electrodes 34 are disposed in the electrolytic cell 33 and, when energized in response to an output signal from the humidifying and purifying device control unit 60, electrolyze the saltwater to produce hypochlorous acid water of a predetermined concentration.

[0052] That is, the hypochlorous acid water generator 30 generates hypochlorous acid water by electrolyzing salt water as an electrolyte between a pair of electrodes constituting the electrode 34 in the electrolytic cell 33. A general device is used for the hypochlorous acid water generator 30, and detailed description thereof will be omitted. The electrolyte is not particularly limited as long as it is capable of generating hypochlorous acid water and contains even a small amount of chloride ions, and examples thereof include aqueous solutions in which sodium chloride, calcium chloride, magnesium chloride, or the like is dissolved as a solute. Hydrochloric acid is also acceptable. In this embodiment, an aqueous chloride solution (salt water) in which sodium chloride is added to water is used as the electrolyte.

[0053] The hypochlorous acid water supply unit 38 supplies hypochlorous acid water from the electrolytic bath 33 of the hypochlorous acid water generation unit 30 to the mixing bath 42 of the micronization unit 41 in response to an output signal from the humidifying and purifying device control unit 60. Specifically, the hypochlorous acid water supply unit 38 is configured to have a hypochlorous acid water transfer pump 36 and a water supply pipe 37. The hypochlorous acid water transfer pump 36 sends out the hypochlorous acid water stored in the electrolytic bath 33 to the water supply pipe 37 in response to the output signal from the humidifying and purifying device control unit 60. The water supply pipe 37 is connected between the hypochlorous acid water transfer pump 36 and the mixing bath 42, and supplies the hypochlorous acid water from the electrolytic bath 33 toward the mixing bath 42.

[0054] Here, in order to ensure the concentration of hypochlorous acid water generated and stored in the hypochlorous acid water generation unit 30 (electrolytic bath 33), the hypochlorous acid water supply unit 38 supplies the entire amount of hypochlorous acid water generated in the electrolytic bath 33 when supplying hypochlorous acid water from the electrolytic bath 33 to the mixing bath 42. Therefore, after the hypochlorous acid water is supplied, the electrolytic bath 33 is empty, and hypochlorous acid water is not produced from a state in which hypochlorous acid water remains in the electrolytic bath 33.

[0055] The water supply unit 48 is configured to include an electrolytic cell supply valve 35, a mixing cell supply valve 45, and a water supply pipe 47. The water supply unit 48 supplies water (tap water) to the electrolytic cell 33 of the hypochlorous acid water production unit 30 and also supplies water (tap water) to the mixing cell 42 of the atomization unit 41 in response to an output signal from the humidifying and purifying device control unit 60. The electrolytic cell supply valve 35 controls whether water supplied from the water supply pipe 47 outside the hypochlorous acid water production unit 30 via a strainer 46 is allowed to flow into the electrolytic cell 33 in response to an output signal from the humidifying and purifying device control unit 60. The mixing cell supply valve 45 controls whether water supplied from the water supply pipe 47 outside the atomization unit 41 via the strainer 46 is allowed to flow into the mixing cell 42 in response to an output signal from the humidifying and purifying device control unit 60. The water supply pipe 47 is connected to the electrolytic cell 33 via the electrolytic cell supply valve 35 and also to the mixing cell 42 via the mixing cell supply valve 45, and supplies water to the electrolytic cell 33 or the mixing cell 42.

[0056] The humidifying and purifying device 40 may also be provided with a drain pan (not shown). The drain pan is disposed in the entire area below the atomization unit 41, the hypochlorous acid water generation unit 30, the hypochlorous acid water supply unit 38, and the water supply unit 48, and is a member that receives the water or hypochlorous acid water that drops from these units. In this case, in addition to the drain pan, it is preferable to provide a drainage pump that drains the water or hypochlorous acid water in the drain pan into a drain drain when the water level in the drain pan reaches a predetermined value.

[0057] The humidifying and purifying device 40 is configured with the above-mentioned components. When the air purifying component hypochlorous acid is not added according to the user's settings, the humidifying and purifying device 40 may operate as a humidifier for increasing the humidity in the living room 2 by using only water as the mixed water to be centrifuged and crushed in the micronizing section 41.

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

[0059] As shown in FIG. 3, the system controller 50 includes a room target temperature and humidity acquisition unit 51, an air conditioning control unit 52, an air conditioner control unit 53, a humidifying and purifying device control unit 60, an air volume control unit 55, and a memory unit 56.

[0060] The room target temperature and humidity acquisition unit 51 acquires the room target temperature and room target humidity (hereinafter also referred to as the room target temperature and humidity) set commonly for the entire room 2 via the input / output terminal 19. The room target temperature is set as a predetermined temperature range defined by a minimum temperature as its lower limit and a maximum temperature as its upper limit. The room target humidity is set as a predetermined humidity range defined by a minimum humidity as its lower limit and a maximum humidity as its upper limit. Here, a temperature equal to or higher than the room target temperature means a temperature equal to or higher than the maximum temperature, and a temperature lower than the room target temperature means a temperature lower than the minimum temperature, which is the lower limit. The same applies to the room target humidity. Note that in this embodiment, the room target temperature and room target humidity can be set by the user, but they may also be set as fixed values ​​in advance in the air conditioning system 20. The maximum and minimum temperatures and maximum and minimum humidity acquired by the room target temperature and humidity acquisition unit 51 or set in advance are stored in the memory unit 56.

[0061] The air conditioning control unit 52 calculates, for each room 2, the difference (temperature difference) between the room target temperature acquired by the room target temperature and humidity acquisition unit 51 or set in advance and the room temperature acquired by the room temperature humidity sensor 54, and the difference (humidity difference) between the room target humidity acquired by the room target temperature and humidity acquisition unit 51 or set in advance and the room humidity acquired by the room temperature humidity sensor 54. Then, based on the temperature difference and humidity difference calculated for each room 2 and the hypochlorous acid concentration setting acquired from the input / output terminal 19, the control conditions for the air conditioner 13, the humidifying and purifying device 40, the conveying fan 3, and the room damper 5 are determined. The control conditions for the humidifying and purifying device 40 are determined by a humidifying and purifying device control unit 60 within the air conditioning control unit 52. The control method of the humidifying and purifying device control unit 60 will be described later.

[0062] The air conditioner control unit 53 controls the operation mode, blowout temperature, and blowing amount of the air conditioner 13 in the air-conditioned room 18a based on the control method determined by the air conditioning control unit 52.

[0063] The humidifying and purifying device control unit 60 controls the humidification amount and hypochlorous acid output of the humidifying and purifying device 40 provided in the air-conditioning room 18a based on the control conditions determined by the air-conditioning control unit 52. Details of the method for controlling the humidification amount and hypochlorous acid output of the humidifying and purifying device 40 will be described later.

[0064] The air volume control unit 55 controls the air volume of the transport fan 3 provided corresponding to the room 2 and the opening degree of the room damper 5 based on the control conditions determined by the air conditioning control unit 52. In this embodiment, the air volume of the transport fan 3 is determined based on either a first air volume control mode determined based on the required air volume calculated by the air conditioner control unit 53, or a second air volume control mode determined based on the required air volume calculated by the humidifying and purifying device control unit 60. The control modes (first air volume control mode and second air volume control mode) for the air volume of the transport fan 3 in the air conditioning control unit 52 will be described later.

[0065] The storage unit 56 is a so-called memory that stores predetermined temperature ranges, i.e., maximum and minimum temperatures, and humidity ranges, i.e., maximum and minimum humidity, acquired or set by the room target temperature and humidity acquisition unit 51. The storage unit 56 is also used when it is necessary to store other information, such as numerical values, for control by the system controller 50.

[0066] Next, the humidifying and purifying device control unit 60 will be described with reference to FIG. 4. FIG. 4 is a control block diagram of the humidifying and purifying device 40. The humidifying and purifying device control unit 60 controls, as processing operations of the humidifying and purifying device 40, operations related to the electrolysis process in the hypochlorous acid water generation unit 30 (electrolytic bath 33), operations related to the supply of hypochlorous acid water to the atomization unit 41 by the hypochlorous acid water supply unit 38 (first supply operation), and operations related to the supply of water to the atomization unit 41 by the water supply unit 48 (second supply operation). The humidifying and purifying device control unit 60 includes a computer system having a processor and memory. The computer system functions as a controller when the processor executes a program stored in the memory. Here, the program executed by the processor is pre-recorded in the memory of the computer system, but it may be recorded on a non-transitory recording medium such as a memory card and provided, or may be provided via a telecommunications line such as the Internet.

[0067] Specifically, the humidifying and purifying device control unit 60 includes an input unit 63, a processing unit 64, an output unit 65, and a timer unit 61, as shown in FIG.

[0068] <Operations related to electrolysis in the hypochlorous acid water generation unit> The humidifying and purifying device control unit 60 causes the hypochlorous acid water production unit 30 to execute the following processes as operations related to the electrolysis process.

[0069] The humidification and purification device control unit 60 receives information (operation stop information) regarding the stoppage of operation of the hypochlorous acid water supply unit 38 (hypochlorous acid water transport pump 36) and information regarding time (time information) from the timing unit 61 as triggers for the electrolysis process in the electrolytic cell 33, and outputs these to the processing unit 64.

[0070] The processing unit 64 identifies control information based on the operation stop information from the hypochlorous acid water supply unit 38, the time information from the timer unit 61, and the setting information from the memory unit 56, and outputs the control information to the output unit 65. Here, the setting information includes information on the start or end time of hypochlorous acid water production, information on the supply amount of tap water introduced into the electrolytic cell 33, information on the amount of salt water introduced into the salt water transfer pump 32, information on the electrolysis conditions (time, current value, voltage, etc.) at the electrode 34, information on the on / off operation of the electrolytic cell supply valve 35 in the water supply unit 48, and information on the on / off operation of the hypochlorous acid water transfer pump 36.

[0071] Here, the electrolysis conditions for the electrode 34 can be determined from the amount of tap water in the electrolytic cell 33, the salt water concentration, the electrolysis time, and the degree of deterioration of the electrode 34, and are set by creating an algorithm and stored in the memory unit 56.

[0072] Then, the output unit 65 outputs a signal (control signal) to each device (brine transfer pump 32, electrode 34, electrolytic cell supply valve 35, hypochlorous acid water transfer pump 36) based on the received control information.

[0073] More specifically, first, the salt water transfer pump 32 maintains a stopped state based on a signal from the output unit 65, and the hypochlorous acid water transfer pump 36 maintains a stopped state based on a signal from the output unit 65.

[0074] The electrolytic cell supply valve 35 is then opened based on a signal from the output unit 65. This starts the supply of tap water from the water supply pipe 47 to the electrolytic cell 33. Thereafter, the electrolytic cell supply valve 35 is closed based on a signal from the output unit 65 that has received water level information (full) from the water level sensor 44a. This puts the electrolytic cell 33 into a state where tap water is being supplied at the set supply rate.

[0075] Next, the salt water transfer pump 32 starts operating based on a signal from the output unit 65, transfers a predetermined amount of salt water to the electrolytic cell 33, and then stops. As a result, chloride ions in the salt water dissolve in the tap water, and the electrolytic cell 33 enters a state in which an aqueous solution containing a predetermined amount of chloride ions (aqueous chloride solution) has been produced.

[0076] Then, the electrode 34 starts electrolysis of the chloride aqueous solution based on the signal from the output unit 65, and stops after producing hypochlorous acid water according to the set conditions. The hypochlorous acid water produced by the electrode 34 has, for example, a hypochlorous acid concentration of 100 ppm to 150 ppm (e.g., 120 ppm) and a pH of 7.0 to 8.5 (e.g., 8.0).

[0077] As described above, the humidifying and purifying device control unit 60 executes electrolysis in the electrolytic cell 33 of the hypochlorous acid water production unit 30, and hypochlorous acid water of a predetermined concentration and amount is produced.

[0078] <Operations related to supplying hypochlorous acid water to the micronization unit> The humidifying and purifying device control unit 60 executes the following process as an operation (first supply operation) related to the supply process of hypochlorous acid water to the micronization unit 41. Note that, hereinafter, the hypochlorous acid water supplied to the micronization unit 41 by the first supply operation is also referred to as "concentrated hypochlorous acid water."

[0079] The humidifying and purifying device control unit 60 requests the hypochlorous acid water production unit 30 (hypochlorous acid water supply unit 38) to supply hypochlorous acid water based on the reduction time required for the mixed water to decrease by a specified amount.

[0080] Specifically, the processing unit 64 identifies control information based on information related to the decrease time and setting information from the storage unit 56, and outputs the control information to the output unit 65. Here, the setting information includes information related to the supply timing of hypochlorous acid water and information related to the on / off operation of the hypochlorous acid water transfer pump 36.

[0081] Then, based on the received control information, the output unit 65 outputs a signal (control signal) to the hypochlorous acid water transfer pump 36 in the hypochlorous acid water supply unit 38. This activates the hypochlorous acid water transfer pump 36, thereby starting to supply the hypochlorous acid water concentrate produced in the hypochlorous acid water generation unit 30 to the micronization unit 41. Note that in order to ensure the concentration of hypochlorous acid water stored in the hypochlorous acid water generation unit 30, the entire amount of the hypochlorous acid water concentrate produced in the hypochlorous acid water generation unit 30 is supplied each time.

[0082] Thereafter, the hypochlorous acid water transfer pump 36 stops based on a signal from the output unit 65 that receives time information (the time required to supply the entire amount) from the timer unit 61. As a result, the hypochlorous acid water supply unit 38 supplies the hypochlorous acid water concentrate from the electrolytic cell 33 to the micronization unit 41 at the set supply amount.

[0083] As described above, the humidifying and purifying device control unit 60 controls the hypochlorous acid water supply unit 38 to supply the hypochlorous acid water concentrate from the hypochlorous acid water generation unit 30 to the micronization unit 41 as the first supply operation.

[0084] <Operations related to the supply of water to the micronization unit> The humidifying and purifying device control section 60 executes the following process as an operation (second supply operation) related to the supply process of water to the micronizing section 41.

[0085] The humidifying and purifying device control unit 60 requests the water supply unit 48 to supply water based on the reduction time required for the mixed water to be reduced by a specified amount.

[0086] Specifically, processing unit 64 identifies control information based on information about the decrease time and setting information from storage unit 56, and outputs the control information to output unit 65. Here, the setting information includes information about the water supply timing and information about the on / off operation of mixing tank supply valve 45.

[0087] Then, output unit 65 outputs a signal (control signal) to mixing vessel supply valve 45 based on the received control information.

[0088] The mixing tank supply valve 45 operates based on a signal from the output unit 65. As a result, the water supply unit 48 starts supplying water from an external water supply pipe via the water supply pipe 47 to the micronization unit 41 (mixing tank 42).

[0089] Thereafter, the mixing tank supply valve 45 stops based on a signal from the output unit 65 that has received water level information (full water signal) from the water level sensor 44a of the atomization unit 41. As a result, the water supply unit 48 supplies water from the water supply pipe 47 to the atomization unit 41 until the set amount of water is reached.

[0090] As described above, the humidifying and purifying device control unit 60 causes the water supply unit 48 to supply water from the water supply pipe 47 to the atomization unit 41 as the second supply operation.

[0091] Next, the control mode of the airflow rate of the transport fan 3 in the air conditioning control unit 52 will be described.

[0092] The air conditioning control unit 52 has two control modes for the air flow rate of the transfer fan 3: a first air flow rate control mode and a second air flow rate control mode.

[0093] The first air volume control mode is a mode in which the air conditioner 13 controls the air volume of the transport fan 3 based on the temperature adjustment operation of adjusting the air temperature (room temperature) in the room 2 to a target temperature (room target temperature). In the first air volume control mode, the air conditioning control unit 52 determines the air volume of the transport fan 3 to be a first air volume based on the temperature adjustment control of the air conditioner 13. More specifically, the air conditioning control unit 52 determines the air volume of the transport fan 3 to be a first air volume in accordance with the temperature difference between the room target temperature set by the user and the room temperature detected by the indoor temperature and humidity sensor 12. Here, the first air volume is set to 340 m 3 / h~1600m 3 / h, for example, 340m 3 / h, 860m 3 / h, 1140m 3 / h, and 1600m 3 / h. The first airflow rate is set to one of four levels: / h. In the temperature regulation control of air conditioner 13, the first airflow rate transitions to a level where the airflow rate is smaller as the temperature difference between the room target temperature and the room temperature becomes smaller.

[0094] The second air volume control mode is a mode in which the humidifying and purifying device 40 controls the air volume of the transport fan 3 based on the humidifying and purifying operation to bring the air in the living room 2 to a target air purification level. The target air purification level is an air purification level (hypochlorous acid set concentration) set by the user, and for example, the air purification level is set in five stages from "Level 1 (low concentration)" to "Level 5 (high concentration)." The higher the air purification level value, the greater the amount of hypochlorous acid supplied, resulting in a purification condition. In the second air volume control mode, the air conditioning control unit 52 determines the air volume of the transport fan 3 as the second air volume based on the humidifying and purifying control by the humidifying and purifying device 40. More specifically, the air conditioning control unit 52 sets the second air volume based on the air purification level set by the user. Here, the second air volume is 340 m, similar to the first air volume. 3 / h~1600m 3 / h, for example, 340m 3 / h, 860m 3 / h, 1140m 3 / h, and 1600m 3 / h. In the humidification and purification control by the humidification and purification device 40, the higher the air purification level, that is, the greater the amount of hypochlorous acid supplied, the greater the second airflow rate.

[0095] Here, from the viewpoint of comfort, it is desirable that the air conditioning control unit 52 basically controls the temperature control operation of the living room 2 as the first priority. Furthermore, during heating operation in which high-temperature, low-humidity air flows into the humidifying and purifying device 40, the amount of hypochlorous acid supplied to the living room 2 increases, while during cooling operation in which low-temperature, high-humidity air flows into the humidifying and purifying device 40, the amount of hypochlorous acid supplied to the living room 2 decreases. For this reason, during cooling operation, the amount of hypochlorous acid supplied to the living room 2 tends to be insufficient, making it difficult to control the amount of hypochlorous acid supplied to the air purification level (hypochlorous acid set concentration) set via the input / output terminal 19. For these reasons, in the present embodiment, when the air conditioner 13 is operating in heating operation, the air conditioning control unit 52 controls the airflow rate of the transport fan 3 in the first airflow control mode, and when the air conditioner 13 is operating in cooling operation, the air conditioning control unit 52 determines the airflow rate of the transport fan 3 by switching between the first airflow control mode and the second airflow control mode.

[0096] Based on the above, the control mode determination process flow in the air conditioning control unit 52 will be described with reference to Fig. 5. Fig. 5 is a flowchart showing the control mode determination process operation of the air flow rate of the transport fan 3 in the air conditioning control unit 52.

[0097] As shown in FIG. 5, in the control mode determination process, the air conditioning control unit 52 first determines whether a predetermined time (e.g., 5 minutes) has elapsed since the previous control determination process (step S01). If the determination result shows that the predetermined time has not elapsed (No in step S01), the process returns to step S01. On the other hand, if the predetermined time has elapsed (Yes in step S01), the control mode of the conveying fan 3 is determined based on the operating state of the air conditioner 13. Specifically, the air conditioning control unit 52 acquires information about the operating state of the air conditioner 13 and determines whether the operating state of the air conditioner 13 is cooling operation (step S02). If the determination result shows that the operating state of the air conditioner 13 is not cooling operation, that is, is heating operation (No in step S02), the air conditioning control unit 52 specifies a first air volume control mode based on the temperature adjustment operation of the air conditioner 13 (step S07). Then, the air conditioning control unit 52 determines the air volume of the conveying fan 3 to be a first air volume and causes the conveying fan 3 to operate at the first air volume (step S08). Then, the process returns to step S01.

[0098] On the other hand, if the determination result in step S02 indicates that the operating state of the air conditioner 13 is cooling (Yes in step S02), a control mode is identified by a control mode determination process (step S03). In the control mode determination process, the air conditioning control unit 52 acquires the temperature (room temperature) of each room 2 from the room temperature and humidity sensor 54 (step S04). Then, the air conditioning control unit 52 calculates the temperature difference between the acquired room temperature of each room 2 and the room target temperature set by the user (step S05). Then, the air conditioning control unit 52 determines whether the calculated temperature difference is less than a reference temperature difference (e.g., 2°C) (step S06). If the calculated temperature difference is not less than the reference temperature difference in all rooms 2, in other words, if the temperature difference is equal to or greater than the reference temperature difference in at least one room 2 and the temperature adjustment control is not in a stable state (No in step S06), the first air volume control mode based on the temperature adjustment operation by the air conditioner 13 is identified as the control mode (step S07). Then, the air conditioning control unit 52 determines the air flow rate of the transport fan 3 to be the first air flow rate, and causes the transport fan 3 to operate at the first air flow rate (step S08). After that, the process returns to step S01.

[0099] On the other hand, if the result of the determination in step S02 is that the calculated temperature difference is less than the reference temperature difference in all of the rooms 2, that is, if the temperature adjustment control is in a stable state (Yes in step S06), the control mode is specified as the second air volume control mode based on the humidifying and purifying operation by the humidifying and purifying device 40 (step S09). Then, the air conditioning control unit 52 determines the air volume of the transport fan 3 to be the second air volume, and operates the transport fan 3 at the second air volume (step S10). Thereafter, the process returns to step S01.

[0100] As described above, the air conditioning system 20 controls the air flow rate of the conveying fan 3 by switching between the first air volume control mode and the second air volume control mode depending on the operating state of the air conditioner 13 and the temperature difference between the room temperature and the target temperature, thereby performing air conditioning control for the room 2.

[0101] As described above, according to the air conditioning system 20 according to the first embodiment, the following effects can be obtained.

[0102] (1) The air conditioning system 20 comprises an air conditioning room 18a configured to be able to introduce air from the living room 2, an air conditioner 13 installed in the air conditioning room 18a and adjusting the temperature of the air in the air conditioning room 18a, a humidifying and purifying device 40 installed in the air conditioning room 18a and performing a humidifying operation on the air adjusted in temperature by the air conditioner 13 while adding hypochlorous acid, an air purifying ingredient, to the air, a conveying fan 3 installed in the air conditioning room 18a and conveying the air that has circulated through the humidifying and purifying device 40 to the living room 2, and an air conditioning control unit 52 (which can also be referred to as a system controller 50) that controls the blowing operation of the conveying fan 3. The air conditioning control unit 52 performs air conditioning control for the living room 2 by switching between a first air volume control mode in which the air conditioner 13 controls the air volume of the conveying fan 3 based on a temperature control operation in which the air temperature (living room temperature) in the living room 2 is adjusted to a target temperature (living room target temperature), and a second air volume control mode in which the humidifying and purifying device 40 controls the air volume of the conveying fan 3 based on a humidifying and purifying operation in which the air in the living room 2 is adjusted to a set hypochlorous acid concentration (set air purification level).

[0103] According to this configuration, during cooling operation, which is a temperature control operation in which the amount of hypochlorous acid water supplied to the living room 2 is likely to be insufficient, the air flow rate of the transport fan 3 is controlled by switching between the first air volume control mode and the second air volume control mode to supply hypochlorous acid to the living room 2, so that a stable supply of hypochlorous acid can be provided so that the set hypochlorous acid concentration is achieved in the living room 2. In other words, the air conditioning system 20 can improve the controllability of the amount of hypochlorous acid supplied during cooling operation.

[0104] (2) Air conditioning system 20 includes living room temperature humidity sensor 54 that acquires the temperature of the air in room 2 as the living room temperature. Air conditioning control unit 52 operates conveying fan 3 in a first air volume control mode when the temperature difference between the living room temperature acquired by living room temperature humidity sensor 54 and the set temperature (living room target temperature) of air conditioner 13 is equal to or greater than a reference temperature difference (e.g., 2°C), and operates conveying fan 3 in a second air volume control mode when the temperature difference is less than the reference temperature difference. As a result, when the temperature difference between the living room temperature and the set temperature is equal to or greater than the reference temperature difference, air conditioning control for room 2 is performed in the first air volume control mode with an air volume that prioritizes temperature adjustment operation. When the temperature difference becomes smaller, less than the reference temperature difference, and the temperature adjustment operation for room 2 is stable, air conditioning control for room 2 is performed with an air volume that prioritizes humidification and purification operation. This allows for a well-balanced adjustment of temperature adjustment and air purification for room 2, and a stable supply of air purification components so that room 2 achieves the target air purification degree.

[0105] (3) When the air conditioner 13 is in heating operation, the air conditioning control unit 52 controls the air flow rate of the transport fan 3 only in the first air volume control mode, and when the air conditioner 13 is in cooling operation, the air conditioning control unit 52 switches between the first air volume control mode and the second air volume control mode to control the air flow rate of the transport fan 3. As a result, during heating operation, which is a temperature control operation that provides a high amount of humidification and makes it easy to supply hypochlorous acid to the living room 2, the first air volume control mode, which prioritizes temperature control operation as before, is maintained, and hypochlorous acid is supplied to the living room 2 so that the target air purification level is achieved. During cooling operation, which is a temperature control operation that makes it difficult to supply hypochlorous acid to the living room 2, the air conditioning control unit 52 switches between the first air volume control mode and the second air volume control mode, and supplies hypochlorous acid to the living room 2 so that the target air purification level is achieved. This enables the air conditioning system 20 to improve the controllability of the hypochlorous acid supply rate during heating operation and cooling operation.

[0106] (4) The humidifying and purifying device 40 includes a centrifugal fan 43b that introduces temperature-controlled air, the temperature of which has been controlled by the air conditioner 13, into the interior, and a micronization unit 41 that releases the temperature-controlled air introduced by the centrifugal fan 43b, containing water that has been micronized by centrifugal crushing. As a result, because the temperature-controlled air is introduced into the interior of the humidifying and purifying device 40 by the centrifugal fan 43b, the amount of ventilation air circulating inside is less affected by the air flow rate of the transport fan 3, making it easier to adjust the amount of hypochlorous acid added to the temperature-controlled air in the air-conditioned room 18a.

[0107] (5) The humidifying and purifying device 40 uses hypochlorous acid water to humidify the temperature-controlled air while adding hypochlorous acid as an air purifying component. As a result, the hypochlorous acid water, which has a disinfecting effect, is atomized in the atomization unit 41 and supplied into the air-conditioned room 18a, so that the living room 2 can be purified with hypochlorous acid.

[0108] The present invention has been described above based on the embodiments, but the present invention is not limited to the above embodiments, and it can be easily inferred that various improvements and modifications are possible within the scope of the invention without departing from the spirit of the invention. [Industrial Applicability]

[0109] The air conditioning system of the present invention can easily adjust the amount of hypochlorous acid released into the air when micronizing hypochlorous acid water and releasing the hypochlorous acid into the air, and is useful as a device for sterilizing or deodorizing the air in a target space.
