The present invention relates to a heat storage tank (shrinkage storage tank and ice storage heat storage tank) that accumulates cooling / heating heat applied to a cooling / heating system or a cooling system using a heat pump and a refrigerator, and more specifically, to reduce the energy use cost of a cooling / heating device. To produce and store cold water or hot water using cheap midnight electricity for the daytime period, the energy cost increases and decreases according to the insulation effect during the storage time, and it has excellent insulation properties and thermal insulation, but also has durability, elastic strength, tensile strength and The present invention relates to a heat storage and a cold storage tank using waste tires excellent in workability.

The heat storage tank and the heat storage tank serve to store the cold and hot heat produced from the air conditioner and supply the stored cold and hot heat to the air conditioning room.

The cold and hot heat storage tank is used as needed, but in recent years, because the economical cooling, heating is possible using the late night electricity and the advantage that can continuously supply the cold and hot heat from the air-conditioning device to the air-conditioning place without interruption It is used as a component of the air conditioning unit.

Since the cold and hot heat storage tank accommodates a circulating medium for storing the cold and hot heat produced from the air conditioning and heating unit and supplying the stored cold and hot heat to the cooling and heating place, and also has a heat exchange unit connected to the air conditioning system. And heat accumulate the hot and cold heat by heat exchange with a circulating medium having cold and hot heat from the air-conditioning unit circulating the heat exchange part through the heat exchange part. By circulating and releasing the accumulated cold and hot heat to perform the cooling and heating for the air-conditioning place.

At this time, the heat storage tank is divided into a shrinkage heat tank (T1) and ice heat storage tank (T2), the shrinkage heat tank (T1), as shown in Figure 1, the outer wall layer 1 is formed of reinforced concrete, the outer wall The inner wall surface of the layer 1 is formed by foaming a heat insulating layer 3 made of urethane foam having a predetermined thickness (for example, 50 mm) by using a primer adhesive layer 2, and on one surface of the heat insulating layer 3 Form a waterproof layer (4) to which the polyurea is applied to a thickness (for example 2mm) of, and the elastic waterproof layer 5 is formed between the primer adhesive layer 2 and the heat insulating layer (3).

However, the shrinkage heat bath (T1) has a disadvantage in that the shape of the urethane foam forming the heat insulation layer (3) is deformed, as the heat dissipation effect is reduced when water is soaked into the heat insulation layer (3) when the elastic waterproof layer (5) is broken. .

In addition, when urethane foam forming the heat insulation layer 3 is compressed by the hydraulic pressure in the contraction heat tank T1, the heat insulation effect is reduced to 50% or less than the thickness at the time of initial construction, as well as the heat insulation effect is deteriorated. When water pressure exceeding the modulus of elasticity of the polyurea constituting the waterproofing layer 4 is generated in the direction of the arrow, as shown in part A of FIG. 2, water is generated in the urethane foam constituting the insulating layer 3 while cracking occurs in the waterproofing layer 4. Absorption of the heat insulation layer 3 is caused by a decrease in heat insulation of the heat insulation layer 3, and in this case, there is a problem in that the urethane foam forming the heat insulation layer 3 floats on the circulating medium stored in the shrinkage heat tank T1. However, there is a problem of enormous budget and time required for reconstruction for repair of defects.

In addition, the contraction heat bath (T1) has a problem of absorbing the polyurea constituting the waterproof layer 4, the urethane foam constituting the heat insulating layer 3 when forming the waterproof layer 4 on the heat insulating layer (3), The heat insulation layer 3 has a disadvantage in that a pin hole is generated, and the heat insulation and waterproofing effect of the heat insulation layer 3 decreases as the moisture penetrates the heat insulation layer 3 in the long term.

In addition, the contraction heat tank (T1) has a disadvantage in that the workability is lowered, as well as a variety of defects, as the problem occurs in the chemical reaction and mixing due to the decrease in the ambient temperature when the construction is made in winter. As described above, when various defects occur, a partial repair thereof is impossible.

On the other hand, Figure 3 shows the ice storage tank (T2), which is almost the same as the drawing of Figure 1 showing the shrinkage heat tank (T1), but a predetermined thickness (for example 50mm on one surface of the heat insulating layer 3 from the bottom surface) After the rootless concrete layer 6 is formed, a waterproof layer 4 made of polyurea having a predetermined thickness (for example, 2 mm) is formed thereon.

At this time, the thickness of the heat insulating layer (3) made of urethane foam in the ice storage tank (T2) is designed to about 100mm.

However, after the ice heat storage tank (T2) is constructed of the rootless concrete layer (6), moisture remains in the thermal insulation layer (3) of the bottom surface, in this case, due to the rootless concrete layer (6) in the thermal insulation layer (3) After the construction of the waterproof layer 4 becomes impossible, the internal moisture remaining as described above expands or contracts as the temperature changes, thereby changing the internal pressure of the ice storage tank T2, thereby preventing cracking of the waterproof layer 4. There is a risk of facilitating, there is a problem of causing a defect by relaxing the urethane foam and polyurea constituting the insulating layer (3) and the waterproof layer (4).

In addition, when water pressure acts in the direction of the arrow on the waterproof layer 4 formed on the rootless concrete layer 6 as shown in FIG. 4, the weight of the rootless concrete layer 6 is increased due to the water pressure, There is a disadvantage that the bottom surface is sunk in the portion B, thereby reducing the heat insulating effect as the compression of the heat insulating layer (3) intensifies, there is a disadvantage that the waterproof layer (4) in the corner portion is broken.

In addition, when expansion or contraction of the wall surface and the bottom surface occurs due to the temperature of the circulation medium in the ice storage tank T2, when the construction methods of the wall surface and the bottom surface are different and the thickness thereof cannot be formed uniformly, waterproof cracking is caused. Of course, the desorption phenomenon is likely to be caused in the adhesive surface between the dissimilar materials (for example, polyurea and urethane foam or urethane foam and reinforced concrete), which inevitably raises the risk of defects in the long term.

Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, the object of the cold / hot heat storage tank divided into a shrinkage heat tank and ice storage tank through the recycling of waste tires by the heat insulating material, by cold / hot heat In addition to improving heat insulation and waterproofing performance of heat storage tanks, and preventing the occurrence of chronic defects caused by breakage of the waterproof layer and heat insulation layer by water pressure, it promotes sound utilization of waste resources, thereby reducing the existing construction cost by saving enormous heat. In order to contribute to the national economy by spreading the spread of heating.
