The present invention relates to a fan coil unit provided with a magnetization water generator for providing corrosion to the inside of the fan coil unit by providing a generator and magnetizing the cold / hot water to the fan coil.

In general, a fan coil unit receives cold water or hot water from a freezer or a boiler during cooling and heating of a building, and passes it through a heat exchanger to cool or heat the surrounding air, and then use the air. It is an air conditioner that performs cooling or heating by discharging to a room by a blower.

The filter 8 which filters the air sucked in is provided in the.

In addition, the upper side of the heat exchanger (1) is provided with a discharge port (6) for discharging the cooled or heated air to the outside, one side of the heat exchanger (1) to the cold and hot water of the pipe (2) A drain 4 for discharging is formed, and a control unit 7 for controlling on / off and strength of the fan coil is provided on the side of the discharge port 6.

At this time, the pipe 2 is made of a cylindrical pipe made of steel or copper, since strong durability is required, and corrosion is inevitably generated on its inner surface depending on the use environment and time.

In particular, in the case of cold and hot water, the inner surface of the pipe 2 is easily oxidized, and as shown in FIG. 2, when a certain time passes, red rust (hereinafter referred to as 'red blue') is made of copper. In this case, green rust (hereinafter referred to as 'cyan') is generated, and due to the red blue (3) or cyan, not only the durability of the pipe (2) is rapidly weakened, but also the inner diameter of the pipe is reduced so that This will interfere with the flow.

Therefore, the flow of cold and hot water circulated into the pipe is weakened, and thus the efficiency of cooling and heating is drastically reduced.

The present invention has been made to solve the above problems, by installing a magnetization water generator on the pipe for supplying cold and hot water in the boiler, by supplying the magnetized cold and hot water to the fan coil corrosion of the fan coil unit It is an object of the present invention to provide a fan coil unit equipped with a magnetization water generator.

In addition, the cold and hot water flowing from the outside is installed to pass through the pump, and the magnetization water generator is installed in the impeller provided inside the pump, the direction of the magnetic field generated in the magnetization water generator is due to the impeller of the pump Another object of the present invention is to provide a fan coil unit having a magnetization water generator that is perpendicular to each other in a direction in which cold and hot water flows into the inside.

The present invention for achieving the above object is to install a magnetized water generator on the supply line of cold and hot water supplied from the boiler, and to supply the fan coil by magnetizing the cold and hot water, to prevent corrosion inside the fan coil unit It has its technical features.

In addition, a seal device and a bearing is provided at one side, and a pump device including a shaft for rotating the impeller by a driving force is provided. On the one side of the impeller or the shaft, a magnetization water generator for generating a magnetic field is installed, and the inside of the pump is provided. It is a technical feature of the magnetizing the incoming cold and hot water to discharge through the casing.

Hereinafter, with reference to the accompanying drawings a fan coil unit equipped with a magnetization water generator according to the present invention will be described in detail.

FIG. 3 is a schematic diagram of a partial cross-sectional process of a state in which a magnetized water generator is coupled to an outer portion of a pipe of a fan coil unit as an embodiment of the present invention, and FIG. 4 is a cross section of a magnetized water generator as another embodiment of the present invention. It is a schematic diagram showing that the magnetized water is supplied to the inside of the fan coil unit, Figure 5a is a schematic cross-sectional view showing a pump having a magnetized water generator as an embodiment of the magnetized water generator shown in FIG. 5b and c are schematic views showing the cold and hot water flow on the pipe when the pump with the magnetization water generator of FIG. 5a is used.

In the present invention, in order to prevent red blue (3) or cyan inside the pipe (2) through which cold and hot water flows, electrons are supplied to the inside of the pipe by an NMR (nuclear magnetic resonance) effect to prevent oxidation of iron or reduce red rust. The magnetic corrosion prevention method which converts into black blue which prevents oxidation was applied.

That is, when water crosses the magnetic field at right angles, red blue (Fe ₂ O ₃ ) is changed to black blue (Fe ₃ O ₄ ) due to the NMR (nuclear magnetic resonance) effect of the magnetic field.

The NMR (Nuclear Magnetic Resonance) refers to a phenomenon in which radio waves of microwaves are selectively absorbed by a specific atomic nucleus susceptible to a moderately strong normal magnetic field, and passes through a strong magnetic field. It instantly magnetizes cold and hot water at high speed.

At this time, the effect generated by the magnetic field is proportional to the square of the magnetic flux density, and the strength of the magnetic force is inversely proportional to the square of the distance. In other words, when the distance is doubled, the magnetic flux density becomes 1/4, and as a result, the induced current becomes 1/16.

Therefore, in the present invention, by applying the above-mentioned anti-corrosion method, the red and blue 3 inside the pipe 2 is prevented by converting cold and hot water flowing inside the pipe 2 forming the heat exchanger 1 into magnetized water. Done.

That is, as shown in Figure 3, the fan coil unit equipped with the magnetization water generator according to the present invention is provided with a heat exchanger (1) for heat exchange with the air is provided with a pipe (2) flowing cold and hot water on the upper side And an air blower 5 for circulating the air downward, and a filter 8 for filtering the air sucked in the lower part of the air blower 8, which is cooled or heated above the heat exchanger. Discharge port 6 for discharging the air to the outside is provided, one side of the heat exchanger (1) is formed with a drain (drain) for discharging the water generated by condensation of water in the air due to the temperature difference to the outside On one side of the pipe of the heat exchanger (1), a magnetization water generator (10) for converting cold and hot water into magnetized water by discharging a magnetic field is coupled.

At this time, the magnetization water generator 10 includes any one of a permanent magnet or an electromagnet, the inlet pipe 11 through which the cold and hot water is introduced into the heat exchanger 1 and the cold and hot water are discharged from the heat exchanger. It is fixedly coupled in a manner surrounding the outside of any one or more of the discharge pipe 12.

Therefore, the cold / hot water passing through the impeller 25 has a faster flow rate than the flow rate v _w flowing through the pipe, and is magnetized by a magnet provided on one side of the impeller 25 and discharged to the casing 24.

At this time, it is preferable that the direction of the magnetic force lines generated in the magnet of the present invention and the moving direction of the cold / hot water flowing into the pump 20 be vertical. (By Fleming's right hand rule)
