A heat exchanger (10) is provided in which a plurality of heat exchange plates (11) are stacked while being spaced apart from each other by a predetermined distance and fluid is moved and heat exchanged through a space between the plurality of heat exchange plates, And a UV LED (20) for applying ultraviolet rays to at least the space between the heat exchange plates, wherein a water repellent coating and a photocatalytic coating are formed on the surface of the heat exchange plate.
Description
The present invention relates to an evaporator, and more particularly, to an evaporator having a photocatalytic coating region and a water-repellent coating region for enhancing photocatalytic reaction and water-repellent efficiency on the surface of a heat exchange plate constituting an evaporator, And a method of controlling the evaporator.
The most problematic aspect of air conditioning using air conditioners is that the temperature of the evaporator of the air conditioner is lower than the air temperature, so that the evaporator always generates water, which causes the growth of bacteria and mold around the evaporator. By forcibly circulating air through the evaporator, these fungi and bacteria float in the air of the air-conditioned room. Not only will it directly harm the body, but it will not be understandable unless you experience the smell that the bacteria reproduce.
In addition, since the evaporator has a structure in which a plurality of heat exchange plates are closely arranged, it is very difficult to clean the space between two neighboring plates even if cleaning is frequently desired. Especially, the evaporator installed in the air conditioner of the vehicle is provided inside the duct, which is installed in a position where the general user can hardly access, so that the evaporator can not be cleaned much even if it is frequently cleaned.
Since bacteria are known to be the cause of odor, many technologies have been proposed to suppress the propagation of bacteria through ultraviolet sterilization effect by directly irradiating the evaporator with ultraviolet rays. In addition, a method of applying an ionizer or a method of applying a photocatalytic filter has been proposed.
However, there is a limit in limiting the propagation of germs in the evaporator by merely irradiating the ultraviolet rays. In addition, sterilization and odor removal efficiency is lower than that of photocatalytic reaction.
Korean Patent Laid-Open Publication No. 2015-25967 proposes a technique utilizing a photocatalytic reaction. However, since the photocatalytic reaction occurs only on the surface of the photocatalyst material, the active radical is separated from the photocatalyst material and can be released There is no way to directly sterilize the bacteria in the evaporator.

It is another object of the present invention to provide a control method for efficiently increasing the photocatalytic reaction effect and the germicidal effect of the heat exchanger.
According to an aspect of the present invention, there is provided a heat exchange apparatus comprising: a plurality of heat exchange plates (11) stacked in a state of maintaining a predetermined gap therebetween, a fluid moving through a spacing space between the plurality of heat exchange plates, And a UV LED (20) that emits ultraviolet rays to at least a space between the heat exchange plates, wherein a water repellent coating and a photocatalytic coating are formed on the surface of the heat exchange plate A heat exchanger is provided.

According to the present invention, since the photocatalyst coating is formed on the surface of the plate for heat exchange, the propagation of microorganisms, bacteria, fungi, and the like is inhibited and sterilized in a heat exchanger in which a water droplet is formed to form a humid environment, The water droplets formed on the surface of the heat exchange plate can be immediately separated from the plate for heat exchange by self weight, thereby blocking the composition of environment in which bacteria and fungi can live.
According to the present invention, a photocatalytic coating region is formed in an area outside the surface of the plate where ultraviolet rays reach and a water repellent coating area is formed in an inner region of the plate where ultraviolet rays hardly reach, thereby improving the photocatalytic reaction efficiency of the photocatalytic coating region, The effect can be sufficiently exhibited.

According to the present invention, the water-repelling guide portion is arranged in such a shape that the water-repellent coating region extends across the photocatalytic coating region so that the water-repellent guiding portion can be easily discharged by its own weight and easily discharges water droplets formed in the photocatalytic coating region .

When the heat exchanger according to the present invention is installed in the vehicle air conditioner, when the vehicle is started, the UV LED is supplied to the heat exchanger by supplying power to the UV LED for a predetermined period of time. This is intended to sterilize bacteria that can be propagated in the evaporator during the time when the vehicle is not in operation through direct irradiation of ultraviolet rays and photocatalytic reaction, and to remove the odor which may be caused thereby.
When the air conditioner is turned on, power is applied to the UV LED so that ultraviolet rays are irradiated to the heat exchanger. When the air conditioner is turned on, the power is constantly applied to the UV LED to prevent the bacteria from propagating due to the water droplets formed in the heat exchanger, and similarly, the flowing air is purified by the photocatalytic reaction to maintain the cleanliness of the indoor air .
Next, when the air conditioner is turned off, power is supplied to the UV LED continuously for a predetermined time, for example, 10 minutes from the time when the air conditioner is turned off, until ultraviolet sterilization And the photocatalytic reaction is continued. If the air conditioner equilibrates with the ambient air temperature, no further water condensation occurs. Therefore, it is preferable to irradiate ultraviolet rays to the heat exchanger for a predetermined time after the air conditioner is turned off.
Although the description has been made with reference to the vehicle in Fig. 9, the above control method can be applied even when the vehicle is not used. That is, the control method of continuously irradiating the evaporator with ultraviolet rays while the air conditioner is turned on or irradiating ultraviolet rays for a predetermined time after the air conditioner is turned off can be applied to other air conditioners as well as vehicles.
10 is a graph showing the degree of decomposition of volatile organic compounds by inducing a photocatalytic reaction using the UV LED used in the present invention with time, and FIG. 11 is a graph showing the results of photocatalytic reaction using UV LED used in the present invention Thereby showing the degree of sterilization of bacteria by time.
The UV LED used in the present invention can be used together with a UV LED that emits ultraviolet rays having a peak wavelength of 365 nm and a UV LED that emits ultraviolet rays having a peak wavelength of 275 nm.
Among the photocatalyst materials used in the photocatalytic filter, it was confirmed that the ultraviolet ray absorption ratio of TiO 2 absorbs the wavelength near 270 nm and the absorption rate linearly decreases toward 400 nm. However, when the actual UV LED was used, it was confirmed that the UV LED having the peak wavelength activated at the highest photocatalytic efficiency was 365 nm. This is because of the luminous efficiency of the UV LED, because the luminous efficiency of the device is drastically lowered for a UV LED having a small peak wavelength. In other words, UV LEDs with low peak wavelengths must use a large number of UV LEDs in order to meet the required ultraviolet intensity at the surface of the photocatalytic filter, but this increases the cost exponentially, and the dense LED packaging also causes heat generation problems. As a result, it was confirmed that the deodorization efficiency of the photocatalytic filter was drastically decreased when UV LED having a peak wavelength of 340 nm or less was used.
In addition, when UV LEDs having a peak wavelength of 380 nm or more are used, the ultraviolet absorption rate of the photocatalyst itself is small and the difference from the conventional lamp type black light is eliminated.
Experimental results show that UV LED with peak wavelength of 360nm or more and 370nm or less can maximize deodorization performance by the photocatalytic filter. Therefore, in one embodiment of the present invention, a UV LED having a peak wavelength of 365 nm is used as an ultraviolet light source for a photocatalyst.
Photocatalytic reaction is excellent in decomposition of organic compounds, and bacteria, which are a kind of organic compounds, are also decomposed. That is, it was confirmed that the photocatalytic reaction has the effect of decomposing the cell membrane of bacteria. However, since the bactericidal effect of these bacteria occurs at the surface of the photocatalyst material, a more reliable sterilizing effect is required.
Accordingly, the present invention intends to increase the sterilization efficiency by additionally using a UV LED for sterilization having a peak wavelength in the UVC region. The UV LED for sterilization is preferably irradiated with ultraviolet light having a peak wavelength of 250 to 280 nm, which is highly sterilizing effective. In particular, when irradiated with ultraviolet rays having a peak wavelength of 265 to 280 nm, it is possible to enjoy both effects of high sterilization efficiency and high TiO 2 photocatalyst absorption rate.
Referring to FIG. 10, a TiO 2 photocatalytic filter having an area of 10 × 10 cm is placed in a chamber of 4 cubic meters (m 3 ), and an ultraviolet ray irradiated on the surface of the photocatalytic filter is irradiated with ultraviolet rays having a peak wavelength of 365 nm If 17.3mW / cm 2, 275nm is irradiated so that the peak 243.4μW / cm 2 when the ultraviolet light having a wavelength, a graph showing the degree to which volatile organic compounds that was in the chamber is decomposed with time.
It can be seen that the ultraviolet ray intensity is small, but the harmful gas removal efficiency is better when ultraviolet rays having a peak wavelength of 275 nm are irradiated together, as compared with simply irradiating ultraviolet rays having a peak wavelength of 365 nm alone.
11, a TiO 2 photocatalytic filter having an area of 10 × 10 cm in a 4-cubic meter (m 3 ) chamber having a humidity of 39 ° C. and RH of 24 ° C. was placed on the surface of the photocatalytic filter, the UV intensity (irradiance) is irradiated when ultraviolet light of 365nm in peak wavelength when the ultraviolet ray of 17.3mW / cm 2, 275nm peak wavelength is irradiated so that the 243.4μW / cm 2, that the bacteria that was in the sterilization chamber over time, FIG. The bacterium is S. aureus ATCC 6538 and the initial condition is 11.7 log CFU / m 3 . The amount of air passing through the photocatalytic filter is 1.29 CMM.
As can be seen from the above, it can be confirmed that the sterilization efficiency is superior when ultraviolet rays having a peak wavelength of 275 nm are irradiated together, although the ultraviolet light intensity is small, as compared with the case of simply irradiating ultraviolet rays having a peak wavelength of 365 nm alone.
In other words, when the UV LED with the peak wavelength of 365 nm is used to focus on the reaction activation of the photocatalytic filter and the UV LED more suitable for direct sterilization is used, the sterilization efficiency can be remarkably increased and the photocatalytic reaction efficiency can be increased .
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed exemplary embodiments. It is obvious that a transformation can be made. Although the embodiments of the present invention have been described in detail above, the effects of the present invention are not explicitly described and described, but it is needless to say that the effects that can be predicted by the configurations should also be recognized.
