Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the building heating panel using a phase change material according to the present invention.

As shown in FIGS. 1 to 4, the building heating panel 100 using the phase change material according to the present invention has a plug terminal 112 and a socket terminal 114 for electrically connecting to both sides to form a power supply. The heat-transfer plate 110 and the heat-transfer plate 110 are formed to have a size corresponding to the heat-transfer plate 110 and are impregnated in the three-dimensional porous body 120 and the three-dimensional porous body 120 arranged on the upper and lower surfaces of the heating plate. The phase change material 130 is formed on the upper and lower surfaces of the polymer phase change material 130 and the heat transfer plate 110, which accumulate heat in the process of changing to the gel phase and release the accumulated heat. Covering the outside of the impregnated three-dimensional porous body 120 is made of a configuration of the closing panel 140 to seal the inside.

The building heating panel 100 using the phase change material according to the present invention configured as described above is a three-dimensional porous body arranged on the upper and lower surfaces of the heat transfer plate 110 when the heating plate 110 is heated by application of power. The phase change material 130 impregnated on the 120 accumulates heat in a process of changing into a gel phase. As such, the floor heating may be maintained for a long time by accumulating heat in the process of changing the phase change material 130 to the gel phase by heating the heat transfer plate 110.

Meanwhile, as described above, power is applied to the heat transfer plate 110 after heat is accumulated in the three-dimensional porous body 120 in the process of changing the phase change material 130 to the gel phase by heating the heat transfer plate 110. Even if blocking the heat radiation is made from the heat storage body consisting of the phase-transfer material 130 and the three-dimensional porous body 120 to heat the floor. At this time, the phase change material 130 is changed to a solid phase in the process of heat dissipation.

In the construction of the building heating panel 100 as described above, the phase change material 120 is composed of one or two selected from the group consisting of polyethylene glycol, polyethylene oxide and polyvinyl alcohol. In particular, polyethylene glycol is changed into a gel phase when heated with a polymer material having a chemical structure of 50,000 g / mol or less of H-[-O-CH2-CH2-] n-OH. As such, polyethylene glycol accumulates heat in the process of changing into a gel phase by heating, and releases heat accumulated in the process of cooling and solidifying, and thus it is possible to repeatedly use it as a heating material.

In addition, the polyethylene glycol as described above used in the present invention is about 200 ~ 20,000g / mol, the melting temperature is increased as the molecular weight is increased, it is possible to set a wide melting temperature according to the selection of molecular weight Therefore, it is possible to manufacture a building heating panel 100 having a heating temperature to be applied according to the selection of the appropriate molecular weight of polyethylene glycol.

In the case of the polyethylene glycol as described above, since the phase separation does not occur, heat is accumulated stably, and heat storage of heat is also stable and heat storage density is high and heat storage density is high, so that about 40 cal or 1 g of polyethylene glycol can be accumulated. In addition, such polyethylene glycol has a high stability enough to be used for cosmetic additives and medical use, and also can be mass-produced at a low price.

On the other hand, as described above, when polyethylene glycol is actually used in an environment in contact with oxygen, there is a disadvantage in that the heat storage capacity is rapidly decreased by aging in a short time while repeated heating and cooling. Therefore, in the present invention, the phase change material 130 is formed in a closed structure through the finishing panel 140 to prevent contact with oxygen to prevent contact with oxygen, as well as phenols or amines or mixtures thereof in the phase change material 130. Radical scavenger was mixed to configure the phase transition material 130 and the contact of oxygen can be blocked. At this time, the radical scavenger is mixed at a ratio of 0.001 to 20% by weight based on the total amount of the phase change material 130. Suitably it mixes in the ratio of 0.01-5 weight%.

In this case, the polyethylene glycol may be used in the form of a slurry by mixing with various fluids such as silicone oil, and of course, it is possible to use a mixture of a plurality of polyethylene glycols having a high melting point and a low one. As a result of mixing and using a plurality of polyethylene glycols having different melting points, the mixture is not too hard even at low temperatures, and the fluid exists even when heated and regenerated, so that the heat conduction efficiency is increased, making melting and heat storage easier. .

On the other hand, in the phase change material 130 configured as described above, a radical scavenger consisting of phenols, amines or mixtures thereof is mixed at a ratio of 0.001 to 20% by weight based on the total amount of the phase change material to block contact between the phase change material and oxygen. It can be configured to be. The radical scavenger is to prevent the phase transition material 130 from oxidizing and aging, and a variety of products are also produced and sold. Among them, phenols such as phenol, cresol, hydrokinone, catechol, anisole, chisylenol, t-butyl-p-cresol, n-nitro sonirin, n-nitrosoamine, phenylene giamine and ethylene giamine And amines and derivatives thereof are most preferred in terms of price and purchase.
