The component units 40A to 40F are configured by combining two gas-liquid contact members, and in this embodiment, twelve gas-liquid contact members 41A1 to 41F1 and 41A2 to 41F2 are used in total. The six component units 40A to 40F are arranged side by side so as to cover substantially the entire surface of the air supply path in the sterilization chamber 120 as will be described later, so that the air flowing through the sterilization chamber 120 is formed by gas-liquid contact without leakage.

(PTFE, PFA, ETFE, etc.) or ceramic materials, PET resin is used in this structure. In addition, the hydrophilic treatment is applied to the component parts to increase the affinity for electrolyzed water, thereby giving the gas-liquid contact members 41A1 to 41F2 water retention (wettability) of electrolyzed water, and active oxygen species (active oxygen species) described later Oxygen species) in contact with room air for prolonged periods of time.

The supply pump 61 is configured to operate under the control of the control unit 65 based on, for example, the electrical conductivity detected in the electrolysis cell 52 .

In addition, the electrolyte added to the water in the water storage tank 51 in order to effectively generate active oxygen species is not limited to salt, and other electrolytes can also be used, for example, potassium chloride, magnesium chloride can be used, and halogen-containing electrolytes containing other halogens can also be used. Various halogen salts of salt, chlorine, and other halogens, and halogen-free electrolytes can also be used. These electrolytes are preferably water-soluble electrolytes.

In addition, 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, so that the electrolyzed water sent by the water supply pump 53 is distributed to each of the electrolyzed water approximately uniformly. Electrolyzed water supply pipes 56A to 56F. The electrolyzed water supply pipes 56A to 56F supply electrolyzed water to the component units 40A to 40F, respectively. The electrolyzed water supplied from the electrolyzed water supply pipes 56A to 56F wets the gas-liquid contact parts 41A1 to 41F2 , flows down from these gas-liquid contact parts 41A1 to 41F2 and is collected in the water receiving pan 44 , and then returns through the circulation return pipe 55 . To the storage tank 51.

The electrolysis unit 52 is fixedly arranged on the side of the water storage tank 51 . Specifically, the electrolysis unit 52 is provided with a bottomed cylindrical body case and at least a pair of electrode plates 72, 73 accommodated in the body case, and by applying a voltage between the electrode plates 72, 73, water is electrolyzed. And generate electrolyzed water containing active oxygen species.

Here, active oxygen species refer to oxygen molecules and related substances that have higher oxidation activity than ordinary oxygen, including so-called narrowly active oxygen species such as superoxide anion, singlet oxygen, hydroxyl or hydrogen peroxide. Oxygen and ozone, hypohalous acid, etc. so-called broad active oxygen.

The electrode plates 72 and 73 are, for example, two electrode plates made of titanium (Ti) as a base, and have a thin film layer containing iridium (Ir) and a thin film layer containing platinum (Pt) on their surfaces, respectively.

When a voltage is applied between the electrode plates 72 and 73, a reaction shown in the following formula (1) proceeds at the cathode electrode (cathode).

2H ₂ O+2e ^- →H ₂ +2OH ^- ......(1)

The reaction shown in the following formula (2) proceeds at the anode electrode (anode).

2H ₂ O→O ₂ +4H ⁺ +4e ^- ......(2)

When the reactions of the cathode electrode and the anode electrode are combined, water is electrolyzed as shown in the following formula (3).

2H ₂ O→2H ₂ +O ₂ ......(3)

Along with this reaction, at the anode electrode, chlorine ions (chloride ions: Cl ⁻ ) contained in water react according to the following formula (4), and chlorine (Cl ₂ ) is generated.

2Cl ^- →Cl ₂ +2e ^- ......(4)

Then, 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)

The hypochlorous acid (a generalized active oxygen species) generated at the anode electrode has strong oxidizing and bleaching effects. The aqueous solution in which hypochlorous acid is dissolved, that is, the electrolyzed water produced by the electrolysis unit 52 exerts various air purification effects such as inactivation of viruses and the like, sterilization, decomposition of organic compounds, and the like. In this way, when the electrolyzed water containing hypochlorous acid flows through the electrolyzed water supply pipes 56A to 56F, and drips onto the gas-liquid contact parts 41A1 to 41F2 via the sprinkler box, the air blown out by the use-side blower 22 is blown on the gas-liquid contact parts 41A1 to 41F2. Contact with hypochlorous acid. As a result, viruses and the like floating in the air are inactivated, and odorous substances contained in the air react with hypochlorous acid to be decomposed or ionized to be dissolved. Therefore, sterilization and deodorization of the air are performed, and the purified air is discharged from the gas-liquid contact members 41A1 to 41F2.

The mechanism of inactivation of viruses and the like by active oxygen species is exemplified by influenza virus. The above-mentioned active oxygen species have the action of destroying and eliminating (removing) the surface protein (spike) of influenza virus required for influenza infection. When this surface protein has been disrupted, the influenza virus and the receptors (receptors) required for infection with the influenza virus do not bind and infection is prevented. Therefore, the influenza virus floating in the air contacts the electrolyzed water containing the active oxygen species at the gas-liquid contact members 41A1 to 41F2, thereby losing its infectivity and preventing infection.

Therefore, by arranging the component units 40A to 40F having the air-liquid contact parts 41A1 to 41F2 in the sterilization chamber 120 of the roof-mounted air conditioner 110, the air flowing through the sterilization chamber 120 passes through the air-liquid contact parts 41A1 to 41F2. As shown in FIG. 1 , the sterilized air can be diffused more widely in the movie theater 100 , and the air sterilization and deodorization in large-space facilities can be easily and effectively performed.

Here, switching of electrodes for applying a positive potential to either side of the electrode plates 72 and 73 in the electrolytic cell 52 can be performed by reversing the polarity of the electrodes. The voltage applied to the electrode plates 72 and 73 is converted (reversed), thereby enabling switching of the electrodes.

In addition, under the control of the control unit 65 , the concentration of active oxygen species in the electrolyzed water is adjusted to a concentration that inactivates viruses and the like that are to be sterilized. The concentration of the active oxygen species is adjusted by adjusting the voltage applied between the electrode plates 72 and 73 and adjusting the value of the current flowing between the electrode plates 72 and 73 . For example, if a positive potential is applied to the electrode plate 72, if the value of the current flowing between the electrode plates 72, 73 is set to a current density of 20mA (milliampere)/cm ² (square centimeter), then a prescribed concentration of free residual chlorine will be produced. (eg 1 mg (milligram)/1 (liter)). In addition, by changing the voltage applied between the electrode plates 72 and 73 to increase the current value, the concentration of hypochlorous acid in the electrolyzed water can be adjusted to a high concentration.

In addition, the water storage tank 51 is provided with a drain pipe 67 that siphons out the water in the water storage tank 51 . The drain pipe 67 has a first vertical portion 67A extending upward from the bottom of the water storage tank 51 , a horizontal portion 67B connected to the first vertical portion 67A and extending in a substantially horizontal direction, and connected to the horizontal portion 67B and outside the tank. The second vertical portion 67C extending downward. The horizontal portion 67B is set at a position slightly higher than the control water level in the normal water storage tank 51, and the water supply in the water storage tank 51 is discharged by opening the water supply valve 58 until reaching the height position, thereby utilizing the siphon principle to discharge the water in the water storage tank 51.

Next, a more specific embodiment of the air conditioner 110 will be described.

FIG. 5 is an external perspective view showing the configuration and installation state of the electrolyzed water circulation supply unit 5 according to this embodiment.
