Next, each configuration of the sterilization unit 150 will be described.
FIG. 4 is a diagram showing a schematic configuration of the sterilization unit 150.
As shown in FIG. 4, the sterilization unit 150 includes an air sterilization unit 4 disposed in the sterilization chamber 120 and an electrolyzed water circulation supply unit 5 disposed adjacent to the sterilization chamber 120. The electrolyzed water circulation supply unit 5 generates electrolyzed water having sterilizing ability and circulates and supplies it to the air sterilization unit 4. The air sterilization unit 4 supplies electrolyzed water and air supplied from the electrolyzed water circulation supply unit 5. Contact to disinfect air.
The air sterilization unit 4 includes six element units 40A, 40B, 40C, 40D, 40E, and 40F. Each of the element units 40A to 40F is configured by combining two gas-liquid contact members. In this embodiment, twelve gas-liquid contact members 41A1 to 41F1 and 41A2 to 41F2 are used. As will be described later, the six element units 40A to 40F are arranged side by side so as to cover almost the entire air passage in the sterilization chamber 120, and the air passing through the sterilization chamber 120 does not leak and the gas-liquid contact member 41A1. It is the structure which passes -41F2.

The gas-liquid contact members 41A1 to 41F2 are members for bringing the electrolyzed water into contact with the air passing through the air passage 120A, and the air flowing through the air passage 120A in these gas-liquid contact members 41A1 to 41F2 generates a predetermined active oxygen species. By contacting with the electrolyzed water, the virus contained in the air is inactivated and the air is sterilized.
The gas-liquid contact members 41A1 to 41F2 are filter members having a three-dimensional structure similar to a honeycomb structure, and have a structure in which an element portion in contact with a gas is supported by a frame. Although not shown, the element portion is configured by laminating a corrugated plate member and a flat plate member, and a plurality of substantially triangular openings are provided between the corrugated plate member and the flat plate member. Is formed. Therefore, a wide gas contact area is ensured when air is passed through the element portion, electrolysis water can be dripped, and the structure is difficult to clog.
The element part is made of a material that is hardly deteriorated by electrolyzed water, for example, polyolefin resin (polyethylene resin, polypropylene resin, etc.), PET (polyethylene terephthalate) resin, vinyl chloride resin, fluorine resin (PTFE, PFA, ETFE, etc.) Alternatively, a material such as a ceramic material is used, and in this configuration, a PET resin is used. In addition, the element portion is subjected to a hydrophilic treatment, and the affinity for the electrolyzed water is enhanced, whereby the water retention (wetability) of the electrolyzed water of the gas-liquid contact members 41A1 to 41F2 is maintained, which will be described later. Contact between the active oxygen species (active oxygen substance) and air is sustained for a long time.

  The number of gas-liquid contact members is determined according to the amount of air passing through the sterilization chamber 120, and the amount of air passing through the air passage 120A and the sterilization ability of each gas-liquid contact member (gas) A suitable number can be calculated from the contact area), and a number of gas-liquid contact members capable of sufficiently sterilizing the air are arranged in the sterilization chamber 120. Taking this embodiment as an example, twelve gas-liquid contact members 41A1-41F1, 41A2-41F2 are used.

  Further, the electrolyzed water circulation supply unit 5 includes a water storage tank 51 (water tank), an electrolysis unit 52 that electrolyzes water in the water storage tank 51 to generate electrolyzed water, and the electrolyzed water in the water storage tank 51 to the air.

A water supply pipe 57 for supplying city water (tap water) or the like to the water storage tank 51 and a water supply valve 58 are connected to the water storage tank 51, and the water supply valve 58 is connected to a float switch FS provided in the water storage tank 51. Based on the operation, the controller 65 controls the opening and closing. Here, the water supply source connected to the water supply pipe 57 and supplying water to the water storage tank 51 may be either city water (tap water) or water stored in a water supply tank. The water stored in the water tank or the like may be water that contains ion species such as chloride ions in advance, such as tap water, or a dilute concentration of chloride ions such as well water. When water is used, the water may be adjusted to tap water by adding chloride ions to the water. In the present embodiment, these are collectively referred to as water.
In this configuration, even when dilute water having a chloride ion concentration such as well water is used for the water storage tank 51, in order to add chloride ions to this water, it is adjusted to a predetermined concentration in advance. A salt water tank 59 is provided, and a salt water supply pipe 60 connected to the salt water tank 59 is connected to the water storage tank 51 via a supply pump 61 and a check valve 62. The supply pump 61 is configured to operate under the control of the control unit 65 based on the conductivity detected by the electrolysis unit 52, for example.

  Moreover, in this embodiment, the electrolyzed water supply pipe 56 connected to the connection port of the water storage tank 51 is branched into six electrolyzed water supply pipes 56A to 56F, respectively. The electrolytic water supply pipes 56A to 56F are divided almost evenly. The electrolyzed water supply pipes 56A to 56F supply electrolyzed water to the element units 40A to 40F, respectively. The electrolyzed water supplied by the electrolyzed water supply pipes 56A to 56F is infiltrated into the gas-liquid contact members 41A1 to 41F2, flows down from these gas-liquid contact members 41A1 to 41F2, is collected in the drain pan 44, and passes through the circulating water return pipe 55. To the water storage tank 51.

The electrolysis unit 52 is fixedly disposed on the side surface of the water storage tank 51. Specifically, the electrolysis unit 52 includes a bottomed cylindrical case body 71 and at least a pair of electrodes 72 and 73 housed in the case body 71, and a voltage is applied between the electrodes 72 and 73. By doing so, water is electrolyzed to generate electrolyzed water containing active oxygen species.
Here, the reactive oxygen species are oxygen molecules having an oxidation activity higher than that of normal oxygen and related substances, and so-called narrow definition such as superoxide anion, singlet oxygen, hydroxyl radical, or hydrogen peroxide. These active oxygens include so-called broad active oxygens such as ozone and hypohalous acid.

The electrodes 72 and 73 are, for example, two electrode plates having a base made of titanium (Ti) and a coating layer made of iridium (Ir) and platinum (Pt).
When a voltage is applied between the electrodes 72 and 73, the cathode electrode (cathode) reacts as shown in the following formula (1).
2H ₂ O + 2e ⁻ → H ₂ + 2OH ⁻ (1)
The anode electrode (anode) reacts as shown in the following formula (2).
2H ₂ O → O ₂ + 4H ⁺ + 4e ⁻ (2)
When the reactions at the cathode and anode electrodes are combined, water is electrolyzed as shown in the following formula (3).
2H ₂ O → 2H ₂ + O ₂ (3)
Along with this reaction, in the anode electrode, chlorine ions (chloride ions: Cl ⁻ ) contained in water react as shown in the following formula (4) to generate chlorine (Cl ₂ ).
2Cl ⁻ → Cl ₂ + 2e ⁻ (4)
Further, this chlorine reacts with water as shown in the following formula (5) to generate hypochlorous acid (HClO) and hydrogen chloride (HCl).
Cl ₂ + H ₂ O → HClO + HCl (5)

  Hypochlorous acid (active oxygen species in a broad sense) generated at the anode electrode has a strong oxidizing action and bleaching action. The aqueous solution in which hypochlorous acid is dissolved, that is, the electrolyzed water generated by the electrolysis unit 52 exhibits various air cleaning effects such as inactivation of viruses and the like, sterilization, and decomposition of organic compounds. Thus, when the electrolyzed water containing hypochlorous acid flows through the electrolyzed water supply pipes 56A to 56F and is dropped onto the gas-liquid contact members 41A1 to 41F2 through the watering boxes 42A1 to 42F2, the blower 22 blows out. The air that has been brought into contact with hypochlorous acid in the gas-liquid contact members 41A1 to 41F2. As a result, viruses or the like floating in the air are inactivated, and odorous substances contained in the air are decomposed by reacting with hypochlorous acid or ionized and dissolved. Accordingly, the air is sterilized and deodorized, and the purified air is discharged from the gas-liquid contact members 41A1 to 41F2.

  An example of influenza virus is given as an action mechanism of inactivation of viruses and the like by reactive oxygen species. The above-mentioned reactive oxygen species have the action of destroying and eliminating (removing) the surface protein (spike) of the virus essential for influenza virus infection. When this surface protein is destroyed, the influenza virus and the receptor (receptor) necessary for the infection of the influenza virus are not bound, and the infection is prevented. For this reason, the influenza virus floating in the air loses infectivity by contacting the electrolyzed water containing active oxygen species in the gas-liquid contact members 41A1 to 41F2, thereby preventing infection.

  Therefore, by disposing the element units 40A to 40F including the gas-liquid contact members 41A1 to 41F2 in the sterilization chamber 120 of the rooftop air conditioner 110, the air passing through the sterilization chamber 120 is allowed to pass through the gas-liquid contact member 41A1. As shown in FIG. 1, the sterilized air can be widely distributed in the movie theater 100, and air sterilization and deodorization in a large space facility can be easily and efficiently performed. Can be done well.

Here, switching of the electrodes for applying a positive potential to any side of the electrodes 72 and 73 in the electrolysis unit 52 can be performed by reversing the polarity of the electrodes. This is possible by changing (reversing) the voltage applied to the electrodes 72 and 73.
Further, the concentration of the active oxygen species in the electrolytic water is adjusted to a concentration that inactivates viruses to be sterilized under the control of the control unit 65. The concentration of the active oxygen species is adjusted by adjusting a voltage applied between the electrodes 72 and 73 and adjusting a current value flowing between the electrodes 72 and 73. For example, when a positive potential is applied to the electrode 72 and the current value flowing between the electrodes 72 and 73 is 20 mA (milliampere) / cm ² (square centimeter), the predetermined free residual chlorine concentration (for example, 1 mg (milligram)). ) / L (liter)). Moreover, the concentration of hypochlorous acid in the electrolytic water can be adjusted to a high concentration by changing the voltage applied between the electrodes 72 and 73 and increasing the current value.

  In addition, the water storage tank 51 is provided with a drain pipe 67 that can drain water by a siphon method. The drain pipe 67 includes a first vertical portion 67A extending upward from the bottom of the water storage tank 51, a horizontal portion 67B extending in a substantially horizontal direction connected to the first vertical portion 67A, and a lower portion outside the tank connected to the horizontal portion 67B. A second vertical portion 67C extending. The horizontal portion 67B is provided at a position slightly higher than the control water level in the normal water storage tank 51. By supplying water to this height position, the drain pipe 67 is evacuated. The water in the water storage tank 51 is discharged according to the principle.

FIG. 5 is a perspective view showing a detailed configuration of the sterilization chamber 120, and is a perspective view illustrating the configuration inside the sterilization chamber 120.
As shown in FIG. 5, in the sterilization chamber 120 of the other chamber 117, six element units 40A to 40F are arranged side by side in the vertical direction, and electrolyzed water supply for supplying electrolyzed water to these element units 40A to 40F. A circulating water return pipe 55 for returning the electrolytic water flowing down from the pipe 56 and the element units 40 </ b> A to 40 </ b> F to the water storage tank 51 (FIG. 4) is disposed on the floor of the sterilization chamber 120.
The electrolyzed water supply pipe 56 is drawn from the water storage tank 51 located outside the sterilization chamber 120 to the sterilization chamber 120 by being wrapped in the outer tube 50A, and the electrolyzed water supply pipe is connected to the sterilization chamber 120 by the branch connector 50C. Branches to 56A to 56F. A flow rate adjustment valve 50B is attached to the electrolyzed water supply pipe 56 upstream of the branch connector 50C, and the flow rate of the electrolyzed water supplied to the element units 40A to 40F can be adjusted. The electrolyzed water supply pipes 56 branched into six by the branch connector 50C are grouped three by three, passed through the heat insulating material hose 50D, and connected to the element units 40A to 40F. Two anti-vibration fittings 50E that support the heat insulating material hose 50D are attached to the inside of the sterilizing chamber 120 in order to prevent the heat insulating material hose 50D from vibrating due to the airflow in the sterilizing chamber 120.

  The inside of the sterilization chamber 120 can be accessed from an external inspection port 125 provided on the outer wall thereof. An internal wall 126 is provided inside the external inspection port 125, and the air blowing space of the sterilization chamber 120 can be reached from the internal inspection port 127 provided in the internal wall 126. This double wall structure is a structure for reliably separating the air passage through which a large amount of air is blown from the outside.

The element units 40A to 40F are configured by assembling various members to two gas-liquid contact members as shown in FIG. That is, the element unit 40A is configured as a horizontally long plate-like unit by connecting plate-shaped gas-liquid contact members 41A1 and 41A2 in the longitudinal direction. A watering box (not shown) for dispersing electrolyzed water uniformly on the gas-liquid contact members 41A1 and 41A2 is assembled to the upper part of each of the gas-liquid contact members 41A1 and 41A2. An electrolyzed water supply pipe 56A is branched and connected to this watering box, and electrolyzed water is supplied. This watering box includes a tray member that temporarily stores electrolyzed water, and a plurality of watering holes (not shown) are opened on the side surface of the tray member, and electrolysis is performed from the watering holes to the gas-liquid contact members 41A1 and 41A2. Water is dripped.
Further, on the upper surfaces of the gas-liquid contact members 41A1 and 41A2, a flow dividing sheet (not shown) is disposed in order to efficiently disperse the electrolyzed water dropped from the watering box in the element portion. The shunt sheet is a sheet (woven fabric, non-woven fabric, or the like) made of a fiber material having liquid permeability, and one or more are provided along the cross section in the thickness direction of the gas-liquid contact members 41A1 and 41A2.
In addition, an electrolyzed water tray that receives water flowing down from the gas-liquid contact members 41A1 and 41A2 is attached to the lower part of the gas-liquid contact members 41A1 and 41A2, and the received water is supplied to the drain pan 44 on the bottom surface of the electrolyzed water tray. A drain hose is installed.
The element unit 40A configured in this way does not create a gap between the wall surface and the element unit 40A on the wall surface located on the side of the air passage of the sterilization chamber 120 (the air passage 120A in FIG. 4). It is fixed via a bracket or the like. Similarly, the element unit 40B is configured by combining two gas-liquid contact members 41B1 and 41B2 with a watering box, an electrolyzed water tray, and a connecting member, and is fixed in the sterilization chamber 120 by a bracket or the like. Similarly, each of the element units 40C to 40F is configured by combining two gas-liquid contact members 41C1 to 41F1, 41C2 to 41F2, a watering box, an electrolyzed water tray, and a connecting member. Fixed to.

  Further, a wind guide plate is attached across the upper end of the element unit 40B and the element unit 40A, and the space between the element unit 40A and the element unit 40B is closed by this wind guide plate (not shown). Similarly, between the element unit 40B and the element unit 40C, between the element unit 40C and the element unit 40D, between the element unit 40D and the element unit 40E, and between the element unit 40E and the element unit 40F, Each is blocked by a wind guide plate. Accordingly, the element units 40A to 40F are arranged without gaps with respect to the air passage 120A, and all of the conditioned air blown into the sterilization chamber 120 by the use side blower 22 passes through the element units 40A to 40F and the rear chamber 121. It has a configuration that can be removed.

As shown in FIG. 5, a drain pan 44 that collects the electrolyzed water that has flowed from the element units 40 </ b> A to 40 </ b> F through the drain hose is disposed below the element units 40 </ b> A to 40 </ b> F. A tube 55 is connected.
In addition to the drain pan 44, a bottom drain pan 46 is disposed on the floor surface in the region where the element units 40A to 40F are disposed. The bottom drain pan 46 is a substantially rectangular water receiving member that receives and stores electrolyzed water that has flowed out of the electrolyzed water trays 43A to 43F, for example, by being scattered from the element units 40A to 40F. It is arrange | positioned so that the large area | region including right under 40F may be covered. A drain water pipe 48 is connected to the bottom drain pan 46, and the tip of the drain water pipe 48 is connected to a drain pipe (not shown) outside the sterilization chamber 120, and the water accumulated in the bottom drain pan 46 is drain water. It is drained out of the system through the pipe 48. The drain pan 44 is disposed on the bottom drain pan 46.

  Further, an eliminator section 80 as a resistance section is disposed on the downstream side of the element units 40A to 40F. The eliminator unit 80 includes an eliminator 81 having a predetermined ventilation resistance. The eliminator 81 suppresses the wind speed of the airflow by applying the airflow resistance to the airflow flowing through the sterilization chamber 120. The eliminator 81 is a filter-like member made of, for example, a synthetic resin sponge or nonwoven fabric.

  As described above, the air sterilization unit 4 causes the electrolyzed water to drop and infiltrate into the element parts of the gas-liquid contact members 41A1 to 41F2, and allows the air to contact the electrolyzed water by allowing air to pass through the element parts. To sterilize. The wind speed of the airflow passing through the air sterilization unit 4 is preferably within a range commensurate with the ventilation performance of the gas-liquid contact members 41A1 to 41F2, and preferably when air is passed at a wind speed significantly exceeding this range. There is no denying the possibility that various events will occur. Specifically, the evaporation rate of water from the element portions of the gas-liquid contact members 41A1 to 41F2 (the evaporation amount per unit time), which reduces the remaining capacity of the sterilization ability because the time during which the air contacts the electrolyzed water is shortened. ) Increases, the remaining capacity of the electrolyzed water supply capacity to the element portion decreases, and the consumption rate of electrolyzed water (consumption per unit time) increases, so that the remaining capacity of the electrolysis capacity by the electrolysis unit 52 decreases. There is a concern that the electrolytic water scatters outside the gas-liquid contact members 41A1 to 41F2. For this reason, it is preferable to allow the air to pass at a preferable speed or a speed equal to or lower than the ventilation performance of the gas-liquid contact members 41A1 to 41F2.

On the other hand, the wind speed passing through the air sterilization unit 4 is affected by the blowing capacity of the use-side blower 22 and the volume of the sterilization chamber 120. For example, when existing equipment is used as each equipment on the heat exchange chamber 119 side in the air conditioner 110, or when equipment already installed in the movie theater 100 is diverted, the blowing capacity of the use side blower 22 is high. It is not necessarily optimized for the air sterilization unit 4, and when the use-side blower 22 having a high blowing capacity is operated, the wind speed of the blown air is within a range suitable for the air sterilization unit 4. The possibility of a significantly higher speed cannot be denied.
Therefore, the air conditioner 110 has a configuration in which an eliminator unit 80 is provided on the downstream side of the air sterilization unit 4 and the wind speed of the conditioned air blown into the sterilization chamber 120 is suppressed using the ventilation resistance of the eliminator unit 80. . Thereby, the state in which the conditioned air passes through the air sterilization unit 4 at a preferable wind speed can be realized by suppressing the wind speed passing through the gas-liquid contact members 41A1 to 41F2, thereby reliably preventing the occurrence of the above-mentioned undesirable events. Can effectively sterilize a large amount of conditioned air.

Note that, depending on the air blowing capacity of the use-side blower 22 and the cross-sectional area of the air passage in the sterilization chamber 120, it may not be particularly necessary to suppress the wind speed. In such a case, an eliminator 81 having a low ventilation resistance may be used. When the wind speed is to be significantly suppressed, an eliminator 81 having a large ventilation resistance may be used.
The downstream side of the eliminator 81 is a rear chamber 121 connected to the air supply duct 105 (FIG. 1) via the supply port 111 (FIG. 3B), and has passed through the air sterilization unit 4 and the eliminator unit 80. Conditioned air is supplied to the air supply duct 105 through the rear chamber 121.

FIG. 6 is a perspective view of a main part showing the detailed configuration of the eliminator unit 80, and is a perspective view showing the main part including the eliminator unit 80 in the sterilization chamber 120. For convenience of explanation, a state in which a part of the eliminator unit 80 is disassembled is shown.
As shown in FIG. 6, the eliminator unit 80 is configured by vertically connecting a plurality of units 80A, 80B, 80C, and 80D.
The unit 80A is configured by fitting an eliminator 81 into a frame 83 fixed to the inner wall of the sterilization chamber 120 by a bracket 82, and fixing the eliminator 81 to the frame 83 by a pressing metal fitting 84. The frame 83 includes a side wall having a thickness for accommodating the eliminator 81 and a protrusion protruding from the side wall. Further, the holding metal fitting 84 is formed by forming a metal wire having elasticity or a synthetic resin into a loop shape. When the eliminator 81 is placed in the frame 83 and fitted into the frame 83, the elasticity of the frame 83 is increased. Maintain the state of being fitted to the protrusion.
Similarly, the units 80B to 80D are configured by fitting an eliminator 81 and a presser fitting 84 into a frame 83.

  These units 80A to 80D are fixed to the wall surface of the sterilization chamber 120 by a bracket 82 (FIG. 5). The unit 80A located at the uppermost part of the eliminator unit 80 is arranged substantially vertically. On the other hand, the unit 80B located at the second stage, the unit 80C at the third stage, and the unit 80D located at the lowermost part have a lower side. It is inclined and arranged so as to face the upstream side of the air passage 120A. That is, the units 80B to 80D form a slope that rises toward the downstream side of the air passage.

  The element units 40A to 40F are arranged side by side as shown in FIG. 5, and the element unit (for example, the element unit 40F) that covers the lower area of the air passage 120A is the element unit 40 (for example, the upper area). The element units 40A) are arranged so as to be sequentially shifted upstream of the air blowing path 120A. That is, the six element units 40A to 40F are arranged from the bottom to the top in the order of the element units 40F to 40A in the height direction, and are arranged from the upstream to the downstream in the order of the element units 40F to 40A in the blowing direction. . According to this configuration, the plurality of gas-liquid contact members 41A1, A2 to 41F1, F2 having a total area larger than the area of the air passage 120A can be arranged in the air passage 120A and arranged in the air passage 120A. Further, the sterilization ability of the gas-liquid contact members 41A1, A2-41F1, F2 can be improved.

  Since the units 80B to 80D of the eliminator unit 80 form a slope according to the arrangement of the element units 40A to 40F, the eliminator unit 80 is within a predetermined distance from each gas-liquid contact member 41A1 to 41F2. Will be placed. For this reason, the wind speed of the wind which passes through each gas-liquid contact member 41A1-41F2 can be suppressed reliably, and conditioned air with a large air volume can be efficiently passed by passing the conditioned air through the gas-liquid contact members 41A1-41F2 at a preferable wind speed. It can be sterilized.

In the sterilization chamber 120, conditioned air is blown from the heat exchange chamber 119 (FIG. 3B) by the use-side blower 22 disposed on one side in the longitudinal direction, toward the rear chamber 121 on the other side. Thus, the airflow flows, and the blowing direction is the direction along the longitudinal direction of the sterilization chamber 120.
And the gas-liquid contact members 41A1-41F2 which comprise element unit 40A-40F are arrange | positioned diagonally with respect to the ventilation direction in the disinfection chamber 120. FIG. For this reason, since the horizontal width of the gas-liquid contact members 41A1 to 41F2 is longer than the horizontal width of the sterilization chamber 120, a wider contact area between the conditioned air and the electrolytic water is ensured.

  Moreover, all the gas-liquid contact members 41A1-41F2 are parallel, and are arrange | positioned diagonally facing the use side air blower 22 with respect to the ventilation direction. That is, it faces the side wall opposite to the partition plate 118 to which the use-side fan 22 is attached. Therefore, since the conditioned air blown into the sterilization chamber 120 from the use-side blower 22 does not easily collide with the gas-liquid contact members 41A1 to 41F2 from the front, there is no concern that the electrolyzed water is scattered by the wind pressure, and the eliminator unit 80 Together with the configuration that suppresses the speed of the wind passing through the liquid contact members 41A1 to 41F2, it is possible to reliably prevent the electrolyzed water from scattering from the gas liquid contact members 41A1 to 41F2.

  Moreover, between each element unit 40A-40F is obstruct | occluded by the baffle plates 47A-47E, and between the side of each element unit 40A-40F and the inner surface of the sterilization chamber 120, a fixing member and the base 36 are used. It is blocked by As described above, the air passage in the sterilization chamber 120 is divided into the upstream side and the downstream side by the element units 40A to 40F arranged in six stages, and the upstream air does not leak and the air of the element units 40A to 40F is not leaked. After passing through the liquid contact members 41A1 to 41F2 and sterilized, it flows to the downstream rear chamber 121.

  Furthermore, the bottom drain pan 46 is arrange | positioned under the eliminator part 80 located in the downstream of the gas-liquid contact members 41A1-41F2 about all the units 80A-80D. In other words, the bottom drain pan 46 covers an area corresponding to all the lower portions of the units 80A to 80D. For this reason, even if the electrolyzed water is scattered from the gas-liquid contact members 41A1 to 41F2, the scattered electrolyzed water hits the air current and hits the eliminator unit 80, falls or flows down along the eliminator unit 80, and the bottom drain pan 46 To be collected. For this reason, the electrolyzed water scattered from the gas-liquid contact members 41A1 to 41F2 does not scatter to the inside of the air conditioner 110 or the air supply duct 105, and is drained to the outside through the drain water pipe 48 from the bottom drain pan 46. Therefore, there is no possibility of causing contamination due to the scattering of the electrolyzed water, and there is no possibility that the electrolyzed water will affect the maintainability and durability of the air conditioner 110. As a result, the reliability of the air sterilization system can be further increased.

As described above, according to the present embodiment, a plurality of air outlets 104 opened in the movie theater 100 as one large space are connected via the air supply duct 105, and each air outlet 104 is connected via the air supply duct 105. An air conditioner 110 that supplies conditioned air is provided, a sterilization chamber 120 is provided in an air passage from the air conditioner 110 toward the plurality of outlets 104, and conditioned air and electrolyzed water are provided in the sterilization chamber 120. Since there are provided a plurality of gas-liquid contact members 41A1 to 41F2 that sterilize the conditioned air by contacting them, and an eliminator unit 80 that provides ventilation resistance to the airflow of conditioned air that passes through the gas-liquid contact members 41A1 to 41F2. By providing ventilation resistance to the conditioned air passing through the sterilization chamber 120 by the eliminator unit 80, the wind speed of the conditioned air in the sterilization chamber 120 can be suppressed. Thereby, since it becomes possible to suppress the wind speed which passes along gas-liquid contact member 41A1-41F2 to the speed suitable for the ventilation performance of gas-liquid contact member 41A1-41F2, specifications, such as the utilization side air blower 22 of the air conditioner 110, etc. Regardless, the gas-liquid contact members 41A1 to 41F2 can be used under suitable conditions, and a large amount of conditioned air can be sterilized efficiently and spread over a large space.
The sterilization unit 150 for sterilizing the air supplied to the large space can be easily installed in combination with the air conditioner 110 without being restricted by the blowing performance of the use-side blower 22. Air can be sterilized efficiently and spread over large spaces.

  Moreover, it is set as the structure which provided the utilization side air blower 22 in the one side of the sterilization room 120, and provided the back room 121 connected to the air supply duct 105 in the other side, Between the utilization side air blower 22 and the back room 121, Since the gas-liquid contact members 41A1 to 41F2 and the eliminator unit 80 are provided, air is blown by the use-side fan 22 by the eliminator unit 80 provided between the use-side fan 22 and the rear chamber 121 together with the gas-liquid contact members 41A1 to 41F2. Thus, the speed of the airflow flowing through the air supply duct 105 can be suppressed, and the speed of the wind passing through the gas-liquid contact members 41A1 to 41F2 can be reliably suppressed. Thereby, for example, even if the blowing capacity of the use side blower 22 exceeds the ventilation performance of the gas-liquid contact members 41A1 to 41F2, the wind speed can be suppressed to a suitable speed.

  Further, the eliminator unit 80 is provided on the downstream side of the gas-liquid contact members 41A1 to 41F2 with respect to the airflow passing through the gas-liquid contact members 41A1 to 41F2, and the bottom drain pan 46 for receiving water is provided below the eliminator unit 80. Therefore, even if the electrolyzed water scatters from the gas-liquid contact members 41A1 to 41F2, this electrolyzed water hits the downstream eliminator section 80 and enters the bottom drain pan 46. For example, the electrolyzed water reaches the air supply duct 105 and the like. There is no fear. Therefore, there is no possibility of causing contamination due to the scattering of the electrolyzed water, and the electrolyzed water has no possibility of affecting the maintainability and durability of the air conditioner 110, and further improves the reliability of the air sterilization system. You can also.

Moreover, while arranging several gas-liquid contact member 41A1-41F2 up and down, gas-liquid contact member 41A1-41F2 which covers the lower area | region of a ventilation path is this air flow path rather than gas-liquid contact member 41A1-41F2 which covers an upper area | region. Since the eliminator unit 80 is configured by a plurality of units 80A to 80F arranged vertically and the unit configuring the lower part is disposed upstream from the unit configuring the upper part, The gas-liquid contact members 41A1 to 41F2 are arranged well in the air passage, and a large amount of air can be efficiently sterilized by the gas-liquid contact members 41A1 to 41F2 whose total area is larger than the opening area of the air passage 120A. By arranging the plurality of eliminator portions 80 in accordance with the arrangement state of the gas-liquid contact members 41A1 to 41F2, the gas-liquid contact members 41A1 to 41A. The velocity of the wind passing through 2 can be reliably prevented.
Moreover, since the eliminator part 80 has been arrange | positioned so that the substantially whole surface of the ventilation path in the disinfection room | chamber 120 may be covered, the wind speed of the wind which passes along a ventilation path can be suppressed reliably and effectively.

  Moreover, according to this embodiment, the air conditioner 110 divides the inside of the housing | casing 114 into three, the heat exchange chamber 119 which accommodated the utilization side heat exchanger 21 and the utilization side air blower 22 in one side is provided, and compression is carried out on the other Since the machine room 116 containing the machine 11 is provided, the sterilization room 120 is provided in the rest, and the conditioned air is circulated through the sterilization room 120, the sterilization formed in the casing 114 of the air conditioner 110 is provided. Since the air sterilization unit 4 can be easily arranged in the microbial chamber 120, a large amount of conditioned air supplied to the movie theater 100 can be sterilized with a simple configuration without increasing the size of the apparatus.

  In the present embodiment, a water circulation method is adopted in which the water received by the drain pan 44 is returned to the water storage tank 51 through the circulation water return pipe 55. By effectively using a small amount of water, the air can be efficiently and efficiently used for a long time. It can be sterilized. Further, since the water level in the water storage tank 51 decreases due to evaporation, the water supply valve 58 is opened by the operation of the float switch FS, and an appropriate amount of tap water is supplied from the water supply port. Thus, by circulating the water, the amount of water used can be reduced compared with the method of discharging the water received by the drain pan 44 as it is, and the running cost when operating the sterilization unit 150 can be reduced. Can be planned. In particular, in the roof top type air conditioner 110 as in the present embodiment, since the amount of air blown into the building 200 is large, the gas-liquid contact members 41A1, A2-41F1, The amount of water supplied to F2 increases according to the amount of air. Therefore, in the rooftop type air conditioner 110, the water saving effect by returning the water received by the drain pan 44 to the water storage tank 51 through the circulating water return pipe 55 is greater.

As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to this. In this embodiment, the gas-liquid contact members 41A1 to 41F2 are arranged in the sterilization chamber 120 formed in the rooftop type air conditioner 110. However, the present invention is not limited to this. For example, the air conditioner It goes without saying that a chamber may be provided in an air supply duct 105 that connects 110 and the air outlet 104 formed in the ceiling portion 103 of the movie theater 100, and the chamber is disposed in the chamber.
In the present embodiment, the water received by the drain pan 44 is returned to the water storage tank 51 through the circulating water return pipe 55. However, the water received by the drain pan 44 is discharged as it is through, for example, the drain water pipe 48. It is good also as a structure. In this configuration, although the amount of water used is increased as compared with the water circulation system, it is not necessary to provide the circulation path 63, so that the equipment cost can be reduced.
In the present embodiment, the element units 40A to 40F are arranged side by side, and the element unit 40F that covers the lower region of the air passage 120A is sequentially shifted upstream of the element unit 40A that covers the upper region. However, the present invention is not limited to this, and the element unit 40F covering the lower region of the air passage 120A is sequentially shifted to the downstream side of the air passage 120A from the element unit 40A covering the upper region. Of course, other detailed configurations can be arbitrarily changed.
