Description

Water purifying device for water and air cooled air conditioner

The present invention relates to a water treatment mechanism of a cold air fan and a cold air heater, and more particularly, to purify water circulated in a cold air fan or a cold air heater using cooling water to prevent deposition of scale and propagation of bacteria on main piping parts. A water treatment mechanism of an air cooling air conditioner.

In general, a water treatment mechanism of a cold / hot air fan or a cold air fan, which has been known so far, will be described with reference to FIG. 1. As a water-air cooling air conditioner, a tank 11, a fallback plate 12, a nozzle 13, and a condenser 14 ), A fan motor 15 and the like are provided in one case. The evaporator 26, the plate heat exchanger 27, and the compressor 28 are separated from the case, but are connected to the condenser 14 to form a circulation path of the refrigerant. In this manner, the coolant in the tank 11 is circulated by the pump 23 to the plate heat exchanger 27, the nozzle 13, the dripping delay plate 12, and the tank 11, and the Air flowing from the lower end is discharged to the outside through the fall delay plate 12, the condenser 14, the fan motor 15. Accordingly, the heat exchange of the water air is performed in the condenser 14 and the plate heat exchanger 27.

By the way, even if the coolant is managed by installing the filter network 17 in the tank 11, the general water contains organic and inorganic matters, and microbes and bacteria are easy to propagate. When metal ions concentrated in minerals meet anions of water, they form poorly soluble salts (scales). Organics contaminate the state of water to colloidal state and are deposited by physical and chemical changes.

This scale deposition phenomenon covers the tank 11 and various pipes as well as the impeller of the pump 23, the plate heat exchanger 27, the nozzle 13, the fallback plate 12, and the fan motor 15. Proceeds to. In the filling material of the plate heat exchanger 27 or the fall delay plate 12 having a large flow path cross section, the scale may be removed in small pieces due to the flow rate, but eventually the flow path cross section is relatively small, such as the nozzle 13. In part, the formation of scales adds to the reduction of the flow path, thereby rapidly degrading the efficiency of the system. The scale formed in the pump 23 burns the impeller and deforms the blade of the fan motor 15.

In addition, an environment in which organic matters are stagnant at a high temperature and high humidity is always formed on the filling material of the dripping delay plate 12 and the bottom surface of the condenser 14, so that various bacteria can be easily reproduced. The air flowing from the bottom of the downfall delay plate 12 is discharged to the outside through the fan motor 15 to pass bacteria through the downfall delay plate 12 and the condenser 14 to spread the bacteria out of the cold / hot air fan. As a result, it may cause illness to residents or pedestrians nearby.

Accordingly, the present invention is to solve the above problems, the water treatment of the water air cooling air conditioner to prevent the accumulation of scale and breeding of bacteria in the main piping parts by purifying the water circulated in the cold air or cold air heater using the cooling water Its purpose is to provide a mechanism.

In order to achieve the above object, the present invention provides an air conditioner that exchanges heat with a refrigerant of the evaporator 26 by flowing cooling water and external air of the tank 11.

Heat exchange means mounted on the flow path of the cooling water and the outside air to form a circulation path of the refrigerant; An ozone generator 20 mounted to supply ozone to the cooling water of the tank 11 through a conduit 22; And a controller 30 installed to apply a high voltage to the ozone generator 20 according to a set condition.

At this time, the condenser 14 is installed on two air passages joined as the heat exchange means, and the nozzle 13 is installed on the air passage on one side.

In addition, as the heat exchange means, a method in which the cooling water nozzle 13 and the refrigerant condenser 24 extends on one air flow path is applied.

As another feature of the invention, the controller 30 includes a sensor unit for detecting the concentration of ozone, a timer unit for varying the operation period, and an output unit for varying the amount of generation so that the concentration value of ozone is maintained in the set range.

Ozone is a pale blue gas with very strong oxidizing power and has a unique odor. When energy is added to the oxygen contained in the air, it changes to an oxygen atom state and the three oxygen atoms combine again to generate ozone, which is about 7 times stronger than chlorine and is chemically safe without leaving any smell or color.

In the related art, it is attempted to mount multiple membrane purification filters or to install an ultraviolet sterilizer in a manner to purify the cooling water of the tank 11. The former has a high installation cost and maintenance cost, and insufficient treatment of minerals. The latter has some effects on the removal of bacteria, but it is not a fundamental solution in the treatment of organic and inorganic materials. On the other hand, the present invention applies ozone to achieve the optimum effect through a suitable device configuration.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the main part of the appliance according to the present invention, and FIG. 2 is a block diagram showing the installation configuration of the appliance according to the present invention. 3 is a block diagram showing an installation configuration according to another example of the present invention.

The present invention relates to an air conditioner for exchanging coolant and outside air of a tank 11 and exchanging heat with a refrigerant of an evaporator 26, and based on heat exchange means mounted to form a circulation path of a refrigerant on a flow path of the coolant and outside air. The ozone generator 20 and the controller 30 are added thereto. In the figure, reference numeral A denotes an air passage, reference C denotes a refrigerant passage, and reference numeral W denotes a cooling water passage.

In FIG. 2, a condenser 14 is installed on two joined air flow paths as the heat exchange means, and a nozzle 13 is installed on the air flow path on one side. In Fig. 3, the method in which the cooling water nozzle 13 and the refrigerant condenser 24 extends on one air passage as the heat exchange means is applied. In both cases, the nozzle 13, the fallback plate 12, and the tank 11, which are cooling water circulation paths, are provided in one case below the condenser 14, 24. The same applies to the plate heat exchanger 27, the evaporator 26, and the compressor 28 separated into the casing to form the refrigerant circulation path toward the condenser 14 and 24 side. The case itself forms the main air path. 2 shows another condenser 14 having another air flow path and the flow path reduction plate 16 is interposed with the nozzle 13, while FIG. 3 shows that the condenser 24 is the same as the upper side of the nozzle 13. Disposed on the air flow path. This is a difference in the function of controlling the discharge of spray cooling water droplets by varying the air temperature of the condenser 14 part in the case, the sameness is maintained in the application of the present invention. In the figure, reference numeral 17 and reference numeral 18 denote filter networks.

The ozone generator 20 of the present invention is mounted to supply ozone to the cooling water of the tank 11 through the conduit 22. Since the ozone generator 20 causes corona discharge due to a high voltage of 6000 V or higher, it separates from the case like the evaporator 26 and induces a conduit 22 to which ozone is injected to the bottom of the tank 11. Ozone introduced into the tank 11 through the conduit 22 is decomposed into oxygen and free oxygen while rising with bubbles. In this process, free oxygen reacts with water and has strong oxidation and sterilizing power to purify water.

The end of the conduit 22 may be placed in a tubular shape, but it is preferable to attach the nozzle. The nozzle causes aeration inside the tank 11 to prevent the stagnation of water as much as possible to enhance the water purification action. In the case of using the aeration function, the conduit 22 is spaced apart from the inlet of the pump 23 so that air bubbles do not enter. This is to prevent bubbles of ozone from causing cavitation in the pump 23. The portion immersed in the tank 11 in the conduit 22 uses a ceramic material to improve sterilization by far infrared rays.

The controller 30 of the present invention is installed to apply a high voltage to the ozone generator 20 according to a set condition. The controller 30 has a voltage transformer and a control element on the PCB substrate. The main configuration of the controller 30 includes a sensor unit for detecting the concentration of ozone, a timer unit for varying the operation cycle, and an output unit for varying the amount of generation so that the concentration value of ozone is maintained in the set range. In the controller 30 of the present invention, the sensor unit is installed inside the tank 11 and detects the ozone amount of the cooling water. The timer unit has a function of operating the ozone generator 20 at an appropriate cycle. The timer uses a type with adjustment knobs that allow the user to adjust the cycle of operation.

The higher the concentration of ozone, the greater the ability to decompose organic and inorganic matters, to prevent scale and corrosion of the tank 11 and pipes, and to maintain a clean state at all times. However, an excessive increase in ozone concentration may cause adverse reactions, so an appropriate range (eg 0.01-0.045 ppm) is required. In order to generate ozone, a positive pulse high voltage is generally required. In the controller 30 of the present invention, the output unit controls the ozone generation amount according to the oscillation frequency change or the pulse width change.

On the other hand, it is also possible to interlock the operation of the ozone generator 20 with the pump 23. If the operation of the pump 23 is stopped for a certain period of time, the operation period of the ozone generator 20 is lengthened so that the stop period is interlocked.

As described above, in the ozone control according to the present invention, the ozone concentration of the appropriate input according to the total flow rate of the cooling water is set, but the accurate detection of the dissolved ozone maximizes the washing effect of the raw water and promotes safety.

The air conditioner according to the constitution of the present invention improves the functions of sterilization, deodorization, bleaching, purification, and disinfection, and also sterilizes various bacteria such as general bacteria, Escherichia coli, yeast, filamentous fungus with strong sterilizing power, so that harmful substances are completely decomposed to discharge pollutants. Few.

4A to 4C show an overall configuration cross-sectional view, an enlarged cross-sectional view of a tank, and a flat cross-sectional view of a tank as an installation configuration according to still another example of the present invention.

This is a water air cooling method in which the condenser 34 and the fan motor 35 are provided on the upper side of the tank 31. The tank 31 of this method is also equipped with an ultraviolet sterilizer 32 and a pump 33, but ozone. When the generator 20 is provided, the ultraviolet sterilizer 32 may be omitted. In this manner, it is possible to apply the above-described ozone generator 20 and the controller 30 together inside the case. The conduit 22 which sprays ozone leads to a point spaced apart from the pump 33 so that air bubbles do not enter the pump 33. The capacity of the ozone generator 20 is reduced as the capacity of the tank 31 is smaller than that of FIGS. 1 to 3, and the operation cycle through the controller 30 can be maintained the same.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention.

According to the above configuration and operation, the present invention has a useful effect of purifying the water circulated in the cold air or cold air using cold water to prevent the accumulation of scale and propagation of bacteria in the main piping parts.
