Further, as a countermeasure when the hypochlorous acid water leaks from the pipe 92, the second drain pan 94 that receives the leaked hypochlorous acid water is separated from the first drain pan 93, the pipe 92 and the generator 89. It is installed outside (outside of the machine) the case 81 across the pump 90 and the flow rate adjusting valve 91.

  According to this, by operating the generating device 89, the pump 90, and the blower 88, hypochlorous acid water generated in the generating device 89 flows through the pipe 92 and is supplied to the spray nozzle 84, and sprayed from the spray nozzle 84. Is done. As a result, the air flowing into the machine from the inlet 82 comes into contact with the hypochlorous acid water sprayed from the spray nozzle 84, and microorganisms such as bacteria in the air are removed.

  Thereafter, the sterilized air passes through the eliminator 85 to remove water droplets in the air. After the water droplets are removed, the air is cooled by the cooling coil 86 and then heated to a predetermined temperature by the heating coil 87. The air is discharged from the delivery port 83 and supplied to the room.

Is generated.

The hypochlorous acid solution (HClO) generated by the above reaction is discharged from the electrolytic bath 36 to the dropping pipe 28 and diluted with the dilution water 39 supplied from the dilution water supply pipe 37. Thereby, slightly acidic electrolyzed water 19 is generated and dropped from the dropping nozzle 27. For example, tap water is used as the dilution water 37.

  The generation device 25 is disposed in the machine, is disposed on the upstream side of the gas-liquid contact chamber 16, is disposed on the downstream side of the prefilter 8, and is positioned below the prefilter 8. ing.

  Below the gas-liquid contact chamber 16 and the production | generation apparatus 25, the common drain pan 41 which receives the slightly acidic electrolyzed water 19 which scattered or leaked is installed. The drain pan 41 is a shallow V-shaped dish member having a flow gradient. The drain pan 41 is provided with a discharge pipe 42 for discharging the drain.

Hereinafter, the operation of the above configuration will be described.
As shown in FIG. 1, when the fan 13 is operated, the air A that has flowed into the interior (inside the machine) of the conditioner casing 2 from the external airflow inlet 3 and the return airflow inlet 4 is filtered by the prefilter 8 and becomes coarse particle dust. Then, dust is removed and sterilized in the air purifier 9, further filtered with the medium performance filter 10 to remove dust in the air, cooled to the outdoor temperature with the cooling coil 11, and predetermined with the heating coil 12. After being warmed to the temperature of, it is sent out into the room from the outlet 5.

The dust removal and sterilization action of the air cleaning device 9 will be described below.
By operating the chemical solution supply pump 35, the diluted hydrochloric acid 23 in the chemical solution tank 24 is supplied to the electrolyzer 36 and electrolyzed, and a hypochlorous acid solution is generated and discharged from the electrolyzer 36 to the dropping pipe 28. At this time, the dilution water supply valve 38 is opened, and the dilution water 39 is supplied from the dilution water supply pipe 37 to the dropping pipe 28, so that the hypochlorous acid solution in the dropping pipe 28 is diluted with the dilution water 39. The slightly acidic electrolyzed water 19 is produced by dilution, and the slightly acidic electrolyzed water 19 is dropped from the dropping nozzle 27 onto the sterilizing element 18 and impregnated.

  In addition, by operating the supply pump 32 of the spraying device 21, the slightly acidic electrolyzed water 19 stored in the storage tank 22 passes through the supply pipe 31 and reaches the washer medium 17 from each spray nozzle 30. Then, a water film is formed on the washer medium 17. The spray efficiency from the spray nozzle 30 and the water film effect of the washer medium 17 increase the contact efficiency between the slightly acidic electrolyzed water 19 and the air, and humidification with high saturation efficiency is performed.

  In this state, the air A that has passed through the pre-filter 8 passes through the eliminator 29 from the air inlet 26 of the gas-liquid contact chamber 16, flows into the gas-liquid contact chamber 16, and flows toward the washer medium 17. At this time, dust and harmful gas in the air A come into contact with the sprayed slightly acidic electrolyzed water 19 and the water film formed on the washer medium 17 and are trapped from the air A and sterilized.

  Further, when the air A passes through the washer medium 17, dust trapped by the washer medium 17 is removed from the washer medium 17 by the slightly acidic electrolyzed water 19 that flows down the washer medium 17. The slightly acidic electrolyzed water 19 that has flowed down the washer medium 17 falls into the storage tank 22 and is stored.

  The air A that has passed through the washer medium 17 then passes through the sterilization element 18. At this time, since the air A contacts the slightly acidic electrolyzed water 19 impregnated in the sterilizing element 18, microorganisms such as bacteria and viruses in the air A are sterilized and reliably removed.

  In this way, the air A that has flowed into the machine is dedusted and sterilized by the slightly acidic electrolyzed water 19 sprayed from the spray device 21 in the gas-liquid contact chamber 16, and after passing through the washer medium 17, When passing through the sterilization element 18, it is further sterilized by contacting the slightly acidic electrolyzed water 19. Thus, since the inflow air A is sterilized in two steps, the sterilization can be surely performed on the inflow air A.

  Incidentally, the slightly acidic electrolyzed water 19 dropped from the dropping nozzle 27 to the sterilizing element 18 comes into contact with the air A while flowing down the sterilizing element 18, and hypochlorous acid which is a main component of sterilization. Is consumed and the concentration decreases. In this way, the slightly acidic electrolyzed water 19 in which the concentration of hypochlorous acid has been dropped from the lower end portion of the sterilizing element 18 to the storage tank 22, and the low-concentration slightly acidic electrolyzed water 19 stored in the storage tank 22 is It sprays from the nozzle 30 for spraying.

  Further, the slightly acidic electrolyzed water 19 sprayed from the spray nozzle 30 descends and is collected in the storage tank 22 and sprayed from the spray nozzle 30 again. Thereby, since the slightly acidic electrolyzed water 19 collected in the storage tank 22 is sprayed from the spray nozzle 30 while circulating, the amount of the slightly acidic electrolyzed water 19 used can be saved.

  Moreover, since the production | generation apparatus 25 is arrange | positioned in the inside of the air conditioner 1, ie, the inside of the conditioner casing 2, the installation space required for installing the production | generation apparatus 25, piping, etc. will install the air conditioner 1. It is included in the required installation space, and thus the installation space can be reduced. In addition, by connecting the piping to the generating device 25 in the machine in advance, it is possible to reduce the piping work at the installation site and reduce the labor of the construction work, thereby shortening the construction period and reducing the cost. it can.

  Further, since the generating device 25 is installed on the upstream side of the gas-liquid contact chamber 16, the generating device 25 passes through the gas-liquid contact chamber 16 and is exposed to the air A containing the slightly acidic electrolyzed water 19. Can be prevented. Thereby, corrosion of the production | generation apparatus 25 can be prevented.

  In the gas-liquid contact chamber 16, the slightly acidic electrolyzed water 19 sprayed from the spray nozzle 30 to the downstream washer medium 17 is scattered on the upstream side in the indoor turbulent flow, but is scattered on the upstream side. The slightly acidic electrolyzed water 19 is captured by the eliminator 29. For this reason, it can prevent that the slightly acidic electrolyzed water 19 falls on the production | generation apparatus 25 installed upstream from the eliminator 29, and, thereby, can prevent the production | generation apparatus 25 more reliably.

  Further, since the generating device 25 is disposed downstream (rear side) from the pre-filter 8, the generating device 25 is protected from dust in the air A flowing into the apparatus from the external airflow inlet 3 and the return airflow inlet 4. be able to.

  In addition, since the prefilter 8 is provided in an inclined posture, a dead space is formed below the downstream side of the prefilter 8, and this dead space can be effectively used as an installation space for the generator 25. Can be miniaturized.

  Further, since the slightly acidic electrolyzed water 19 scattered from the spraying device 21 or leaked from the generating device 25 or the storage tank 22 can be received by one drain pan 41, the drain pan 41 is used as the drain pan for the spraying device 21 and the generating device 25. Therefore, it is not necessary to divide the drain pans separately and install them separately, and the number of drain pans 41 can be reduced.

  Further, since the chemical tank 24 is disposed outside the air conditioner 1, the dilute hydrochloric acid 23 is easily replenished from the outside of the air conditioner 1 even when the air conditioner 1 is in operation. be able to. At that time, the existing chemical tank 24 may be replenished with dilute hydrochloric acid 23, but in particular, the chemical tank 24 itself is exchanged with a new one so that the chemical liquid is not exposed to the outside air or hitting a person.

  Further, since the chemical liquid tank 24 and the generating device 25 are arranged on the downstream side of the pre-filter 8, the chemical liquid tank 24 and the generation are generated from dust in the air A flowing into the apparatus from the external airflow inlet 3 and the return airflow inlet 4. The device 25 can be protected.

  Moreover, since the dead space formed under the downstream side of the pre-filter 8 can be effectively used as an installation space for the chemical liquid tank 24 and the generating device 25, the air conditioner 1 can be reduced in size.

  Further, since the slightly acidic electrolyzed water 19 scattered from the spraying device 21 or leaked from the generating device 25, the storage tank 22 or the chemical liquid tank 24 can be received by one drain pan 41, the number of drain pans 41 can be reduced. .
