Description

  The present invention relates to an air conditioner, and more particularly, to an air conditioner including an air purifying unit that purifies air using cleaning water.

  Conventionally, as an air conditioner that adjusts the temperature and humidity of indoor and outdoor air, it has air purification means that removes particulates and gaseous substances contained in the air by bringing cleaning water into contact with the air. It has been known.

  In such an air conditioner, when the washing water is circulated for a long time and the steady operation is performed, the washing water is concentrated by evaporation. However, if the washing water is excessively concentrated, a problem of scale generation occurs. . Therefore, replenishment or replacement of cleaning water is necessary, but the degree of concentration of cleaning water varies depending on the operating conditions and the surrounding environment, so it is difficult to control the timing of water replenishment or water replacement by operating time. . Therefore, there is a problem that the amount of water used increases depending on the frequency of water replenishment or water exchange.

  Therefore, for the purpose of accurately controlling the timing of such water exchange, Patent Document 1 proposes a method of measuring the conductivity of water and determining the timing of water exchange based on the measurement result. Yes.

Japanese Patent No. 4753823

  However, in the above-described method, it is necessary to separately prepare a conductivity detecting means for measuring the conductivity, which leads to an increase in cost.

  Therefore, an object of the present invention is to provide an air conditioner that can appropriately determine the timing of replenishment or replacement of cleaning water without increasing costs.

In order to achieve the above-described object, the air conditioner of the present invention accommodates intake and exhaust ports, wash water, circulates wash water along a circulation path, and removes air introduced from the intake port. Detected by the air purifying means for purifying by being brought into contact with the wash water, the first temperature / humidity detecting means for detecting the dry bulb temperature and the relative humidity of the air introduced from the intake port, and the first temperature / humidity detecting means. Calculating the absolute humidity of the air introduced from the air inlet from the dry bulb temperature and relative humidity, and calculating the evaporation amount per unit time of the wash water based on the calculated absolute humidity; Determination means for determining whether or not the cleaning water stored in the air purification means needs to be replenished or replaced based on the calculated evaporation amount per unit time. In one aspect, the calculating means is based on the difference between the absolute humidity of the air introduced from the air inlet and the absolute humidity of the air purified by the air purifying means, and the amount of air introduced from the air inlet per unit time. The amount of evaporation per unit time of the wash water is calculated. In another aspect, the calculating means calculates the air introduced from the inlet per unit time calculated from the absolute humidity of the air introduced from the inlet and the amount of air introduced from the inlet per unit time. The amount of evaporation per unit time of the wash water is calculated from the amount of water contained and the amount of water contained in the air purified by the air purification unit per unit time.

  In such an air conditioner, the amount of cleaning water evaporated by gas-liquid contact can be grasped from the dry bulb temperature (air temperature) of air introduced from the intake port (inlet air) and the detected value of relative humidity. . The temperature and relative humidity of the inlet air can be detected by a simple method without requiring a complicated configuration. Therefore, it is possible to monitor the evaporation amount of the cleaning water without increasing the cost, and thereby it is possible to appropriately determine the timing of replenishment or replacement of the cleaning water.

  As mentioned above, according to this invention, the air conditioning apparatus which can determine appropriately the timing of replacement | exchange of washing water can be provided, without increasing cost.

It is a schematic diagram of the humid air diagram for demonstrating the calculation method of the absolute humidity of the air purified with the air purification means of this embodiment.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic view showing a configuration of an embodiment of an air conditioner of the present invention.

  The air conditioner 1 includes an intake port 11 provided on the lower side surface of the housing 10, an exhaust port 12 provided on the upper side surface of the housing 10, and an air purification means 20 accommodated in the housing 10. Have.

  The air purification means 20 contains cleaning water, circulates the cleaning water along the circulation path, and purifies the air by bringing the air introduced into the housing 10 from the intake port 11 into contact with the cleaning water. It is like that. For this reason, the air purifying means 20 includes a circulation tank 21 for storing cleaning water, a packed tower 22 constituting a gas-liquid contact portion where the cleaning water comes into contact with air, and a watering nozzle 23 for sprinkling the cleaning water into the packed tower 22. And have. Above the circulation tank 21 installed at the bottom of the housing 10, a packed tower 22 and a watering nozzle 23 are installed in this order. The air purifying means 20 has a circulation pump 24 for circulating the wash water.

  Wash water stored in the air purification means 20 and used for purifying air is not particularly limited as long as it is clean water, and tap water, well water, distilled water, pure water, electrolytic water, or the like may be used. it can.

  An external water source 32 is connected to the circulation tank 21 via a pipe 31, and cleaning water from the external water source 32 can be replenished and replaced by controlling a water supply valve 33 provided in the pipe 31. . Further, a drain valve 25 for draining water is provided on the bottom surface of the circulation tank 21. Furthermore, the circulation tank 21 has a pair of electrodes, and electrolysis means 26 is provided for electrolyzing the wash water to generate chlorine (hypochlorous acid), and to suppress the propagation of germs in the wash water. Is provided.

  A packed tower 22 supported by a support (not shown) and filled with Raschig rings as a packing material is provided above the circulation tank 21 with the intake port 11 interposed therebetween. Wash water sprayed from the upper water spray nozzle 23 adheres to the surface of the Raschig ring, and gas-liquid contact with the air rising from below is performed on the surface. Other fillers that are commonly used in the packed tower 22 such as a lessing ring, a pole ring, a saddle, and a sulzer packing can be used. Instead of the packed tower 22, a plate tower can be used. Moreover, the gas-liquid contact part may be comprised from the mat-like fiber assembly which has a flat upper surface and a rough and rough lower surface. An example of such a fiber assembly is Saran Lock (registered trademark) of Asahi Kasei Home Products Corporation.

  The watering nozzle 23 is, for example, a pipe having a large number of holes, and discharges cleaning water from the holes. The shape of this pipe is not particularly limited, and a pipe having an arbitrary shape such as a plurality of straight or concentric pipes or spiral pipes can be selected as long as the washing water is uniformly sprayed to the packed tower 22. . As the watering nozzle 23, a known watering nozzle such as a sprinkler, a shower, a sprinkler, or a spray type can be used as appropriate, but a spray type is preferable. In the spray type, the sprayed water is mist-like and the particle size is fine. Therefore, not only can the packing material of the packed tower 22 be efficiently wetted, but also the mist-like water sprayed from the spray can be brought into contact with the air to be treated to purify the air to be treated. The liquid contact efficiency is increased. Moreover, since water can be sprayed over a wide area from one nozzle, the number of parts can be reduced.

  The circulation pump 24 has a primary side (suction side) connected to the circulation tank 21 via a pipe 27, and a secondary side (discharge side) connected to the watering nozzle 23 via a pipe 28. Then, a circulation path is formed from the pipe 27, the circulation pump 24, the pipe 28, and the watering nozzle 23, and the washing water can be circulated. In the present embodiment, the circulation pump 24 is provided outside the housing 10. However, the circulation pump 24 may be provided inside the housing 10 as long as the cleaning water is circulated. Further, the circulation pump 24 may be a submersible pump provided in the circulation tank 21.

  Above the air purifying means 20, there is provided a humidity adjusting means for removing a large amount of moisture contained in the air purified by the gas-liquid contact method. In the present embodiment, the desiccant rotor 40 is used as the humidity adjusting means.

  The desiccant rotor 40 has a rotatable rotor 41 holding a desiccant therein, and forms a moisture absorption region 42 in a certain angular range with respect to the rotation axis C of the rotor 41. In the moisture absorption region 42, the air containing a large amount of moisture and having passed through the air purification means 20 passes through the rotor 41 in the thickness direction of the rotor 41 upward. At that time, the moisture of the air is absorbed by the desiccant held inside the rotor 41. On the other hand, the remaining angle range is a reproduction area 43. There, the high-temperature air from the regeneration heater 13 is sent downward to the moisture-absorbing desiccant, and the moisture contained in the desiccant is removed. That is, a part of the rotor 41 is reproduced in the reproduction area 43. Since the rotor 41 rotates at a constant rotational speed, each region (angular position) of the rotor 41 switches between the moisture absorption region 42 and the regeneration region 43 at regular time intervals. Since the regeneration heater 13 is installed in the regeneration heater chamber 14 that is spatially separated from the air flow path inside the housing 10, the regeneration high temperature air does not contact the desiccant that is absorbing moisture. .

  The generation of high-temperature air for regeneration of the desiccant rotor is performed by taking a part of the dried air that has exited the desiccant rotor 40 into the regeneration heater chamber 14 by the regeneration chamber fan 15 and using the air taken into the regeneration heater chamber 14 as the regeneration heater 13. This is done by heating at Part of the moisture of the desiccant rotor 40 absorbed by the high-temperature air is sent to the packed tower 22 and reused as washing water, and the remainder is returned to the regenerative heater chamber 14 and released to the atmosphere.

  Above the desiccant rotor 40 and before the exhaust port 12, an upward driving force is applied to the air introduced from the intake port 11, and the air purified by the air purification means 20 is discharged from the exhaust port 12. The blower 16 is installed. The purified air may be exhausted from the exhaust port 12, and an exhaust unit that exhausts air from the exhaust port 12 may be provided outside the housing 10 instead of the blower 16. .

  Note that cleaning water heating / cooling means for heating or cooling the cleaning water may be provided in the suction-side piping 27 or the discharge-side piping 28 of the circulation pump 24 or in the circulation tank 21. The washing water heating / cooling means is preferably constituted by a heat exchanger and a heat source for heating or cooling the heat medium of the heat exchanger. The heat source is preferably a heat source capable of both heating and cooling, and a heat pump, an absorption chiller / heater, a heating / cooling device using a Peltier element, or the like can be used. Further, the washing water heating / cooling means may have a configuration in which a heating means and a cooling means are provided separately and they are switched appropriately. In that case, as the heat source of the heating means, a boiler, a combination of cogeneration exhaust heat and a boiler can be used, and as the heat source of the cooling means, an absorption refrigerator, an absorption refrigerator utilizing exhaust heat and an electric A combination with a drive refrigerator can be used.

  Here, the air conditioning operation using the air conditioning apparatus 1 of the present embodiment will be briefly described.

  When the blower 16 is activated, the inside of the housing 10 is in a reduced pressure state, and the air to be purified is introduced from the air inlet 12 into the housing 10. The introduced air is given an upward driving force by the blower 16, flows from the bottom to the top in the housing 10, and reaches the packed tower 22.

  On the other hand, the wash water stored in the circulation tank 21 is supplied to the watering nozzle 23 by the circulation pump 24. The washing water supplied to the watering nozzle 23 is sprayed to the packed tower 22 by the watering nozzle 23 and adheres to the surface of the Raschig ring of the packed tower 22 to form a wet surface.

  The air rising from below the packed tower 22 makes gas-liquid contact on the surface of the Raschig ring, and particulate matter and gaseous chemical substances in the air are removed by the wash water. The purified air has a high humidity due to the gas-liquid contact, is dehumidified by ventilating the desiccant rotor 40, and is discharged from the exhaust port 12 by the blower 16.

  In such an air conditioner 1, the cleaning water evaporates due to gas-liquid contact in the packed tower 22, and the cleaning water in the circulation tank 21 gradually decreases when performing steady operation for a long time. It will be. Therefore, it is necessary to periodically replenish the cleaning water. However, accurately knowing the evaporation amount (decreasing amount) of the cleaning water and knowing the appropriate replenishment timing means that the circulation pump 24 is engaged with air. This is important in terms of preventing the electrolysis means 26 from being exposed to air. Further, although the decrease in the washing water is eliminated by replenishment, the concentration of the washing water proceeds as the replenishment is repeated, and if it is excessively concentrated, there is a risk of scale generation. Therefore, the cleaning water needs to be replaced as well as refilled. Accurate control of the replacement timing is effective not only from the viewpoint of scale generation suppression but also from the viewpoint of water saving effect.

  For this purpose, the air conditioner 1 of the present embodiment calculates the evaporation amount per unit time of the wash water, and replenishes or replaces the wash water in the circulation tank 21 based on the calculated evaporation amount. A controller 50 for determining timing is included. In addition, the intake port 11 is provided with a first temperature / humidity monitor 51 that detects the dry bulb temperature (air temperature) and the relative humidity of the air (inlet air) introduced from the intake port 11. Further, the controller 50 calculates the evaporation amount per unit time of the cleaning water based on at least the dry bulb temperature of air and the relative humidity detected by the first temperature / humidity monitor 51. Details of the evaporation amount calculation method will be described later.

  The evaporation amount is calculated every predetermined time during the steady operation, and the evaporation amount calculated every predetermined time is integrated. Depending on whether the integrated value is equal to or higher than the predetermined value, the cleaning water is replenished or It is determined whether an exchange is necessary.

  FIG. 2 is a flowchart showing the timing determination operation for replenishment or replacement of cleaning water, which is performed in the air conditioning apparatus 1 of the present embodiment.

  First, the evaporation amount per unit time of the wash water is calculated based on a calculation method described later (step S1). Then, based on the evaporation amount per unit time, the evaporation amount of the cleaning water evaporated within the predetermined period is calculated (step S2). Here, in the case where the timing determination operation is performed for the first time after replenishing or replacing the cleaning water before, the predetermined period means the time that has elapsed since the cleaning water was replenished or replaced. Means the time elapsed since the previous evaporation amount was calculated.

  Next, the evaporation amount of the cleaning water within the calculated predetermined period is integrated (step S3). When the timing determination operation is performed for the first time after replenishing or replacing the cleaning water before, the calculated evaporation amount is stored in the controller 50 as an initial value. Further, when the timing determination operation is performed thereafter, the calculated evaporation amount is added to the integrated value stored in the controller 50 to obtain a new integrated value. At this time, the controller 50 stores two integrated values. One is an integrated value from the previous replenishment of cleaning water, and the other is an integrated value from the previous replacement of cleaning water. The calculated evaporation amount is added to each integrated value, and each becomes a new integrated value. Note that the two integrated values stored in the controller 50 are reset when only the cleaning water is replenished when cleaning water is replenished, and when the cleaning water is replaced. Is also reset.

  Then, it is determined whether or not each of these integrated values (integrated evaporation amount) is not less than a predetermined value (step S4). If the integrated evaporation amount is not less than the predetermined value, it is necessary to replenish or replace cleaning water. It is determined that there is, and the cleaning water is replenished or replaced (step S5).

  It is determined that replenishment of the washing water is necessary when the accumulated evaporation amount from the previous replenishment of the washing water becomes a predetermined value or more. Here, for example, when the overflow drain port is provided in the circulation tank 21, the predetermined value serving as the determination criterion for replenishment of the wash water is the overflow water level and the operation guaranteed minimum water level (the circulation pump 24 is air-engaged or electrolyzed. This is the amount of water corresponding to the difference from the lowest water level at which the means 26 is not exposed.

  On the other hand, as described above, the concentration of the cleaning water progresses as it is replenished, and if the degree of the cleaning water exceeds a certain level, there is a risk of scale generation. In other words, if the replenishment of the washing water is repeated more than a certain amount and the total amount of the replenishment amount exceeds a predetermined value, the possibility of scale generation increases. In the above replenishment of the wash water, the replenishment amount of the wash water substantially corresponds to the evaporation amount of the wash water. Therefore, the total replenishment amount of the wash water is equal to the accumulated evaporation amount from the previous replacement of the wash water. Substantially equivalent. Therefore, it is determined that the replacement of the cleaning water is necessary when the accumulated evaporation amount from the previous replacement of the cleaning water is equal to or greater than a predetermined value corresponding to the total replenishment amount that serves as a guideline for scale generation. .

  It should be noted that the predetermined value in the replacement of the cleaning water is changed according to the operating conditions, the surrounding environment, and the quality of the cleaning water used. In addition, when it is determined that replenishment of cleaning water and replacement of cleaning water are necessary at the same time, naturally, priority is given to replacement of cleaning water.

  On the other hand, if any integrated evaporation amount is less than the predetermined value in step S4, steps S1 to S3 are repeated until any integrated evaporation amount exceeds the predetermined value. When the cleaning water is replenished or replaced, the timing determination operation ends.

  Next, a method for calculating the evaporation amount per unit time of the cleaning water will be described with reference to FIGS.

  FIG. 3 is a flowchart illustrating an example of a method for calculating the evaporation amount per unit time of the cleaning water by the air-conditioning apparatus 1 of the present embodiment.

  First, the first temperature / humidity monitor 51 detects the dry bulb temperature (air temperature) and the relative humidity of the air (inlet air) introduced from the intake port 11 (step S11), and at the same time, is provided at the intake port 11. The flow rate of the inlet air (the amount of air introduced per unit time) is detected by the air flow meter 29 (see FIG. 1) (step S12). Further, the air density of the inlet air is calculated from the temperature of the inlet air detected in step S11 (step S13).

  Next, the absolute humidity (weight absolute humidity) of the inlet air is calculated from the temperature and relative humidity of the inlet air detected in step S11 (step S14). Specifically, the saturated vapor pressure is calculated from the temperature of the inlet air, and the absolute humidity of the inlet air is calculated from the saturated vapor pressure and relative humidity.

  Next, the wet bulb temperature of the inlet air is calculated from the temperature and relative humidity of the inlet air detected in step S11 (step S15). As an example, the wet bulb temperature of the inlet air can be calculated from the temperature and relative humidity of the inlet air using a humidity table for a ventilation type moisture meter. In addition, it is possible to calculate the wet bulb temperature from the temperature and relative humidity of the inlet air, and to calculate the wet bulb temperature, or to directly read the value of the wet bulb thermometer. But we can get wet bulb temperature.

  Next, as shown below, the absolute humidity of the purified air (purified air) is calculated from the wet bulb temperature of the inlet air calculated in step S15 (step S16). Here, the purified air means the air purified by the air purification means 20 and before passing through the desiccant rotor 40. In FIG. 4, the schematic diagram of the humid air diagram for demonstrating the calculation method of the absolute humidity of purified air is shown. In the wet air diagram, the state of the purified air in the water-spreading air conditioner is on the same isothermic bulb temperature line as the inlet air state (see point A in FIG. 4) and is humidified by gas-liquid contact. Thus, it is known that the line moves to the upper left (see the arrow in the figure). Assuming that the relative humidity of the purified air is 100%, the dry bulb temperature (air temperature) of the purified air can be read from the intersection of the isohumid bulb temperature line and the saturated air line (see point B in FIG. 4). This is equivalent to the wet bulb temperature of the inlet air. From the temperature and relative humidity (assumed to be 100%) of the purified air thus obtained, the absolute humidity of the purified air is calculated as in the case of the inlet air.

  Next, the amount of increase in absolute humidity is calculated from the absolute humidity of the inlet air calculated in step S14 and the absolute humidity of purified air calculated in step S16 (step S17). Then, the mass of air introduced per unit time is calculated from the air volume detected in step S12 and the air density calculated in step S13. This mass and the increase in absolute humidity calculated in step S17 are calculated. From the amount, the moisture added from the wash water to the air per unit time, that is, the evaporation amount per unit time of the wash water is calculated (step S18).

  In addition, as the air volume used when calculating the mass of the air described above, a value set in the blower 16 as an operating condition can be used instead of the detected value by the anemometer 29.

  FIG. 5 is a flowchart showing another example of a method for calculating the evaporation amount per unit time of the wash water by the air-conditioning apparatus 1 of the present embodiment.

  In the calculation method shown in the flowchart of FIG. 3, the absolute humidity of the purified air is calculated on the assumption that the relative humidity of the purified air is 100% and the air temperature is the wet bulb temperature of the inlet air. It is also possible to calculate the absolute humidity of the purified air. The calculation method shown in the flowchart of FIG. 5 is different from the calculation method shown in the flowchart of FIG. 3 in terms of a method of calculating the absolute humidity of the purified air. Hereinafter, only steps different from the calculation method shown in the flowchart of FIG. 3 will be described.

  In the air conditioning apparatus 1 of the present embodiment, the purified air purified by the air purification means 20 is dehumidified by the desiccant rotor 40 and then exhausted from the exhaust port 12. Therefore, by detecting the amount of moisture contained in the air exhausted from the exhaust port 12 (exit air) and the amount of moisture absorbed by the desiccant rotor 40, the amount of moisture contained in the purified air can be known. Here, since the amount of moisture absorbed by the desiccant rotor 40 is equal to the amount of moisture contained in the air (desiccant exhaust air) regenerated from the desiccant rotor 40, the amount of moisture contained in the purified air is the amount of moisture contained in the outlet air. It is calculated from the amount and the amount of water contained in the desiccant exhaust air.

  For this reason, in the calculation method shown in the flowchart of FIG. 5, in addition to the temperature and relative humidity of the inlet air detected in step S11, the temperature of the outlet air is detected by the second temperature / humidity monitor 52 provided at the exhaust port 12. Then, the relative humidity is detected (step S21), and the temperature of the air (desiccant exhaust air) regenerated by the third temperature / humidity monitor 53 provided on the regeneration air discharge side for regenerating the desiccant rotor is detected. And relative humidity is detected (step S22).

  Then, the absolute humidity of the outlet air and the desiccant exhaust air is calculated from the air temperature and relative humidity of the exit air and the temperature and relative humidity of the desiccant exhaust air as in the case of the inlet air (step S23).

  In the calculation method shown in the flowchart of FIG. 5, the amount of water contained in the outlet air and the desiccant exhaust air per unit time is calculated from the absolute humidity of the exit air and the desiccant exhaust air. Specifically, it is included in the outlet air per unit time from the absolute humidity of the outlet air, the air density of the outlet air, and the air volume of the outlet air (the amount of air discharged from the exhaust port 12 per unit time). The amount of moisture is calculated. In addition, the amount of moisture contained in the desiccant exhaust air per unit time is determined from the absolute humidity of the desiccant exhaust air, the air density of the desiccant exhaust air, and the air volume of the desiccant exhaust air (the amount of air discharged per unit time). Calculated. Then, the amount of water contained in the air purified per unit time (the amount of water contained in the purified air per unit time) is calculated from these amounts of water (step S24).

  Note that the air volumes of the outlet air and the desiccant exhaust air are detected by an air flow meter (both not shown) provided at the exhaust port 12 and the exhaust side of the desiccant rotor 40 in step S12, as in the case of the inlet air. Alternatively, the values set in the blower 16 and the regeneration chamber fan 15 as operating conditions can be substituted. Further, the air densities of the outlet air and the desiccant exhaust air are calculated in step 13 in the same manner as in the case of the inlet air.

  Further, based on the absolute humidity of the inlet air calculated in step S14, the air volume detected in step S12, and the air density calculated in step S13, the amount of water introduced from the inlet 12 per unit time (unit: The amount of water contained in the inlet air per hour is calculated (step S25). Then, from the amount of water contained in the inlet air and the purified air per unit time, the moisture added from the wash water to the air per unit time, that is, the evaporation amount per unit time of the wash water can be calculated (step) S18).

  As described above, in the calculation method shown in the flowchart of FIG. 5, the increase amount of the absolute humidity is not calculated from the calculation of the absolute humidity of the purified air. Therefore, steps S15 to S17 in the calculation method shown in the flowchart of FIG. I will not.

  In the case of an air conditioner without a desiccant rotor, the purified air is discharged as it is from the exhaust port, so the temperature and relative humidity of the purified air are directly detected by the temperature and humidity monitor provided at the exhaust port. can do. The absolute humidity of the purified air can be calculated from the temperature and the relative humidity of the purified air thus detected, whereby the increase amount of the absolute humidity, that is, the evaporation amount per unit time of the cleaning water can be calculated. .

  In any of the calculation methods described above, the use environment and operating conditions of the air conditioner 1 are not considered. Therefore, the evaporation amount of the cleaning water can be calculated more accurately by correcting each detection value according to the use environment and operating conditions of the air conditioner 1. For this reason, the air conditioning apparatus 1 can be additionally provided with various detection means.

  For example, at least one of the intake port 11 and the exhaust port 12 may be provided with a pressure monitor that detects the pressure of at least one of the air introduced from the intake port 11 and the air exhausted from the exhaust port 12. Further, when a cleaning water heating / cooling means for heating or cooling the cleaning water is provided, for example, a water temperature detecting means for detecting the temperature of the cleaning water is provided in the circulation tank 21 to monitor the temperature of the cleaning water. It may be like this.

  As described above, the cleaning water evaporates due to gas-liquid contact, and the cleaning water is replenished accordingly, whereby the cleaning water is concentrated. As the concentration of the washing water proceeds, for example, the chloride ion concentration increases, so the conductivity of the washing water also changes. Therefore, when electrolysis of washing water is performed under a certain condition, hypochlorous acid is generated more than necessary, and chlorine odor is mixed with the purified air. In order to avoid such a problem, the current flowing between the electrodes of the electrolysis means 26 is appropriately set to an optimum value according to the change in the conductivity of the washing water, and the concentration of hypochlorous acid generated is set. It needs to be maintained properly.

  In the present embodiment, the conductivity between the electrodes of the electrolysis means 26 is detected to calculate the conductivity of the washing water, and the electrolytic current is calculated from the calculated conductivity and the temperature of the washing water according to a predetermined relational expression. An optimal value can be determined. Therefore, although not shown in FIG. 1, the air conditioner 1 of the present embodiment includes a voltage detection unit that detects the voltage between the electrodes of the electrolysis unit 26, and a water temperature detection that detects the temperature of the cleaning water. Means. The controller 50 also functions as a control unit that determines the current that flows between the electrodes of the electrolysis unit 26 based on these detection values.

  As described above, in the air conditioner of this embodiment, the dry bulb temperature (air temperature) and the relative humidity of the air (inlet air) introduced into the device are detected, and evaporated by gas-liquid contact based on the detected value. It is possible to grasp the amount of water to be washed. The temperature and relative humidity of the inlet air can be detected by a simple method without requiring a complicated configuration. Accordingly, it is possible to monitor the evaporation amount of the cleaning water without increasing the cost, and thereby it is possible to appropriately determine the timing of replenishment or replacement of the cleaning water.
