Hereinafter, a window having a phase change material according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional perspective view of a condensation preventing device including a phase change material according to an embodiment of the present invention.

As shown in FIG. 1, the condensation preventing apparatus 100 according to the exemplary embodiment of the present invention is a hollow case 110 and is built in the case 110 and changes in phase according to ambient temperature to store heat or heat. It includes a phase change material 120 that emits and a heat insulating material 125 to surround the phase change material 120 inside the case 110 to delay the phase change time of the phase change material 120.

The cross section of the hollow case 110 may have a polygonal shape so that one side thereof may be attached to a window or a curtain wall. In FIG. 1, the case 110 of the hollow part has a square cross section, but the cross section of the case 110 of the hollow part may be formed in various shapes such as a hexagon as well as a square.

The case 110 may be formed of a material such as a synthetic plastic resin material or a metal material. When the case 110 is formed of a metal material, the case 110 may be formed of a material having high thermal conductivity such as copper, silver, or aluminum.

One side of the case 110 may be provided with attachment means 130 to be attached to a window or curtain wall. In FIG. 1, although the double-sided tape was used as the attachment means 130, a bond or the like having an adhesive force detachable to the attachment means 130 may be used.

On the other hand, the surface is not provided with the attachment means 130 is attached to the sheet paper or veneer 111 having a beautiful pattern to feel the beauty in appearance.

As the pattern used for the sheet or the veneer 111, various patterns such as a grate pattern or a taeguk pattern, which are Korean traditional patterns, may be used.

The phase change material 120 embedded in the case 110 and phase-changed according to an ambient temperature to store or release heat may be selected from the group including organic materials, inorganic materials, and combinations thereof. In this case, the phase change material 120 may include organic materials such as paraffin wax and polyethylene wax, and these may be used alone or in a mixture.

In general, the higher the concentration, the higher the concentration of the heating effect is increased, in the condensation prevention apparatus 100 according to an embodiment of the present invention by adjusting the concentration of the phase change material 120, the phase change material 120 The phase change temperature of was set to 20 ~ 30 ℃. That is, the phase change material 120 provided in the condensation preventing apparatus 100 according to an embodiment of the present invention is a liquid at room temperature of 30 ° C. or higher, and when the heat is released at about 20˜30 ° C., the phase change material becomes a solid. . As described above, the phase change material 120 phase-changed into a liquid releases heat to the surroundings as the phase change back to a solid when the ambient temperature decreases.

On the other hand, the case 110 is provided with a heat insulating material 125 surrounding the phase change material 120 and delaying the phase change time of the phase change material 120. The reason for installing the heat insulator 125 inside the case 110 is to delay the time point at which the phase change material 120, which absorbs heat to change phase into a liquid state, releases heat while changing to a solid state.

The insulation 125 may include at least one of a foamed plastic, a vacuum insulation panel (VIP), and a fumed silica vacuum insulation material. As the expanded plastic, EPS (Expanded Polystyrene), XPS (Extruded Polystylene), EVA (Ethylene Vinyl Acetate), EPP (Expanded Polypropylene) may be used.

Figure 2 is a graph showing the change in the outdoor temperature and the indoor temperature of the windows installed in the boundary between the outdoor and the indoor with the change of time in winter.

As shown in FIG. 2, the outdoor side temperature (OT) and the indoor side temperature (IT) of the window in winter are the highest at around 14-15 o'clock, when the temperature of the atmosphere is the highest, and the temperature of the dawn is 5 ~ Lowest around 6 o'clock.

Therefore, when the condensation preventing device 100 having the phase change material 120 according to an embodiment of the present invention is installed on the indoor side of the window to be described later, the phase change material provided inside the condensation preventing device 100 ( The temperature of 120 is increased to 20 to 30 ° C. or more, which is a phase change temperature, to change phase into a liquid state.

As time passes, the indoor temperature (IT) of the window is gradually lowered, so that the phase change material 120 is in a solid state when the temperature of the phase change material 120 falls below 20 to 30 ° C. As it phase changes, it releases heat. However, in fact, dew condensation occurs most frequently at about 5-6 am when the indoor temperature (IT) of the window is the lowest, so that the phase change material 120 in the liquid state is installed by installing the insulation 125 inside the case 110. The phase transition to a solid state should be near 5-6 am. As such, the phase change material 120 in the liquid state is delayed in the solid state by using the heat insulator 125 to release the most heat at 5-6 pm in winter, at 5-6 pm in winter. Condensation that occurs intensively can be prevented.

Therefore, the heat collecting part 141 collects heat generated by the phase change material 120 and then releases heat through the heat dissipating part 142. Therefore, when the phase change material 120 releases heat, an attachment means ( The temperature at which the surface 130 is provided is the highest.

Meanwhile, the width of the heat dissipating part 142 may be greater than the width of the heat collecting part 141, which causes the heat collected from the heat collecting part 141 to be concentrated to the heat dissipating part 142. This is to effectively increase the temperature of the surface provided with (130).

Figure 4 is a cross-sectional perspective view of the condensation preventing apparatus according to another embodiment of the present invention.

Exists outside of. As such, the heat dissipation unit 142 is located outside the case 110, so that the heat generated from the phase change material 120 when the condensation preventing device 100 is attached to a window or curtain wall is transferred to the window or curtain wall. Can increase the efficiency of delivery.

Meanwhile, when the case 110 is formed of a metal material having high thermal conductivity, the case 110 may have a greater effect when formed of a synthetic plastic resin material having a low thermal conductivity.

Figure 5 is a cross-sectional perspective view of the condensation preventing apparatus according to another embodiment of the present invention.

In the condensation preventing apparatus 100 according to another embodiment of the present invention, the area of one side of the case 110 is formed to be wider than that of the other side.

Since the cross section of the case 110 has such a shape, the width of the heat dissipating part 142 in the heat conducting conductor 140 can be much larger than that of the heat collecting part 141, so that the attachment means 130 is provided. It is possible to minimize the heat is released to the surface other than the surface, it is possible to maximize the heat emitted to the surface provided with the attachment means (130).

FIG. 6 is a perspective view of a window having a phase change material according to an embodiment of the present invention, and FIG. 7 is a sectional view of a window having a phase change material shown in FIG.

As shown in FIG. 6, the window 200 may include an outer frame 210 fixed to a wall of a building, and an inner frame 220 installed to slide on the outer frame 210.

The dew condensation prevention device 100 can be easily attached to the glass 230 by using the attachment member 130 because the attachment member 130 is provided on one side of the dew condensation prevention device 100. [ When the condensation preventing device 100 is attached to the glass 230, the glass 230 is attached to a surface facing the indoor space. More specifically, the inner frame 220 and the glass 230 are attached to the vicinity of the fixing member 240 provided in the contact area with each other. Because the condensation phenomenon is likely to occur in winter because the insulation is not well near the fixing member 240, by attaching the condensation preventing device 100 near the fixing member 240 to prevent the condensation in the winter. Can be. Hereinafter, a process of preventing condensation in winter in the window 200 having the phase change material 120 will be described.

Even in winter, the temperature of the window 200 receiving solar heat during the day is raised to 30 ℃ or more. Therefore, the phase change material 120 of the condensation preventing device 100 attached to the window 200 absorbs heat to change phase from solid to liquid and to store heat.

On the other hand, it is assumed that the critical temperature at which the condensation may occur on the surface of the glass 230 toward the interior space in winter is 8 ° C.

At dawn in winter, the outdoor temperature drops below 10 ° C., so the temperature of the surface of the glass 230 located at the boundary between the outdoor space and the indoor space may drop below 8 ° C., which is a temperature at which condensation may occur. .

However, since the phase change temperature of the phase change material 120 filled in the condensation preventing device 100 is 20 ~ 30 ℃, when the temperature of the surface toward the interior space of the glass 230 drops, the phase change material 120 is in a liquid state As the phase changes from the solid to the solid state, the stored heat is released to the surroundings. Accordingly, the temperature of the surface of the glass 230 to which the condensation preventing device 100 is attached is increased to prevent the condensation from occurring on the window 200.

Meanwhile, the condensation prevention device 100 may be attached to the window 200 as described above, but a phase change material may be provided on the window 200 to prevent condensation in winter.

Since the temperature of the glass 232 installed in the space formed between the glass 231 and 232 and the indoor space becomes high, condensation may be prevented from occurring. At this time, the spacer 250 is made of copper, silver or aluminum so that the heat emitted from the phase change material 120 inside the spacer 250 can be transferred to the space formed between the two glasses 231 and 232 and the interior space. It may be formed of a metal material having high thermal conductivity.

On the other hand, the heat transfer conductor 140 may be provided inside the spacer 250 to induce heat generated from the phase change material 120 to the glass 232 installed at the indoor space.

When the surface in contact with the glass 232 provided on the indoor space side is referred to as the second contact surface 250b, the area of the second contact surface 250b is larger than the area of the first contact surface 250a.

Since the cross section of the spacer 250 has such a shape as described above, the heat generated from the spacer 250 is moved more toward the second contact surface 250b than on the first contact surface 250a and is installed on the indoor space. Since the temperature of the glass 232 can be effectively increased, condensation can be prevented.

In this case, a heat transfer conductor 140 may be provided inside the sealing material 241 to induce heat generated from the phase change material 120 to the glass 232 of the indoor space. Since the structure of the heat transfer conductor 140 is the same as described in the above-described embodiment, a detailed description thereof will be omitted. Meanwhile, the heat dissipation part 142 of the heat conduction conductor 140 is installed in the direction of the glass 232 installed on the indoor space side. Therefore, the heat generated from the phase change material 120 filled in the sealing material 241 can effectively increase the temperature of the glass 232 installed on the indoor space side, thereby preventing condensation.

Meanwhile, in FIG. 11, the phase change material 120 is filled in the sealing material 241, but the phase change material 120 is not filled in the sealing material 241 but is mixed with the sealing material 241. It could be.

Accordingly, the heat insulation bar 321 is provided in the extrusion processing part of the predetermined shape provided in the longitudinal direction in the horizontal support member 320. The insulation bar 321 is formed by filling a liquid polyurethane insulation into the extrusion processing part to obtain a predetermined portion of the extrusion processing part through a hardening process, which adopts a method of injecting and separating polyurethane of Azon's polyurethane. It is feasible.

The glass 330 is coupled to upper and lower portions of the horizontal support member 320 and the other horizontal support members disposed vertically. A sealing material 322 is disposed between the heat insulation bar 321 of the horizontal support member 320 and the glass 330 disposed on the heat insulation bar 321 to block the inflow of air from the outside to prevent heat conduction more effectively. To prevent.

As such, the sealing material 322 is interposed to prevent a direct thermal conduction phenomenon between the inner glass surface of the glass 330 and the horizontal support member 320 formed of aluminum.

Meanwhile, a gasket 340 may be inserted between the horizontal support member 320 and the glass 330 such that the horizontal support member 320 closely contacts the glass 330. As such, the glass 330 is firmly fixed to the horizontal support member 320 due to the repulsive force by the gasket 340 inserted between the horizontal support member 320 and the glass 330, and the glass 330 and the horizontal support member ( It is possible to prevent the penetration of air or moisture between the 320).

Meanwhile, in the curtain wall according to the embodiment of the present invention, the glass 330 is formed of two glasses 331 and 332, and the plurality of glasses 331 and 332 are spaced apart from each other at a predetermined interval.
