Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat storage and heat dissipation device and a heat storage and heat dissipation method using the same,

The present invention relates to a heat storage and heat dissipation device, and a heat storage and heat dissipation method using the same.

In recent years, there has been a growing interest in technologies that can reduce energy costs and reduce greenhouse gas emissions by reducing the cost of energy consumed nationwide by securing economic efficiency by improving energy efficiency of industry.

Among the various methods that can improve the efficiency of energy use in industry, there is a storage system as a representative technology for recovering and recycling unused waste heat that can not be used. Techniques for efficient storage and utilization of heat energy through heat storage systems have been studied over a wide range. The heat storage system aims at the stable supply and supply of the heat source to recover the unused thermal energy through the storage of the thermal energy, the supply of the energy and the temporal inconsistency of the demand, and it can be applied in various ways, Is applied.

In order to utilize the heat storage system in the existing thermal network, it is essential to supply and recover the heat medium through the piping connection between the stored space and the use place. However, it is difficult to secure economical efficiency even if piping is installed considering economic situation such as location of customer, various situations according to usage pattern, and installation cost of piping. In the case of urban areas, it is difficult to expand the network due to excessive installation cost of heat supply piping. In the case of the outskirts of cities, there is a problem that the cost of construction is increased according to the length of piping, There is a problem of economical deterioration due to heat loss due to long-distance supply due to the reduced heat supply density.

As a solution to this problem, a heat delivery technique for supplying heat using a transportation means rather than a piping-based heat supply can be used as an alternative. Heat-transfer technology is a technology that transfers heat energy to a regenerator, stores it, transports it to a destination by transportation, uses heat, and repeats the cycle of using the heat source again as a means of transportation after use.

Generally, a heat storage container performs heat transfer between a heat source and a container by using a gas or a liquid medium while filling a container with sensible heat or a phase change material (PCM). The waste heat generated in the furnace process of the steelworks or the incinerator process is stored in a heat storage container, and then it is transported to heat the heat source of the nearby greenhouse or the vinyl house to be used for heating, thereby reducing the frequency of using expensive heating fuel A heat delivery system is being operated to reduce heating costs. A related prior art is Korean Patent Publication No. 2009-0102944.

However, conventional heat storage systems store heat by using a sensible storage method of a single substance such as metal or oxide, or a phase change method using latent heat energy in accordance with a change between solid-liquid in water or paraffin. However, There is a problem in that the volume per unit volume is increased due to the storage density and the efficiency per volume is decreased.

In addition, since the enthalpy difference of a single substance is used for heat storage, continuous heat loss occurs immediately after the heat storage. If the temperature is not timely correlated with the customer in a timely manner or spatially remote, the heat utilization efficiency is low .

In the conventional heat storage system, it is difficult to match irregular new or renewable heat or waste heat production to the point of use of the consumer. In order to minimize the enthalpy loss, heat must be utilized as soon as possible during heat dissipation or storage. There is a problem that it is difficult to efficiently control the use of heat.

The heat storage and heat dissipation device includes a plurality of reaction parts 100 for accumulating or releasing heat using a chemical reaction and a plurality of reaction parts 100 connected to the reaction part 100 when the reaction part 100 is stored, A reaction part 100 for removing a substance separated from the thermochemical material inside and providing a substance for reacting thermochemical substances in the reaction part 100 when the reaction part 100 is radiated, An opening and closing part 300 for opening and closing the passage of the supply part 200 to control the reaction of each of the plurality of reaction parts 100, a pipe part 400 connected to the plurality of reaction parts 100, And a valve unit 500 for opening and closing the valve unit 400. The valve unit 500 is controlled to control the flow path of the heat-exchanging fluid with the reaction unit 100.

The reaction unit 100 may perform heat storage or heat dissipation by using a chemical reaction, an adsorption reaction, a desorption reaction, or the like. Here, the chemical reaction means that a new material is generated due to the rearrangement of the material. The adsorption reaction means that the solute molecules remain at the interface of the solid surface at the interface, and the desorption reaction means that the adsorbed material is separated at the interface. Accordingly, as shown in the example of FIG. 2, the reaction part 100 can be heat-treated using a chemical reaction or a desorption reaction, or can be cooled using a chemical reaction or an adsorption reaction.

For example, the thermochemical material may include MgO, CaO, Mg (OH) ₂ and Ca (OH) ₂ as an inorganic oxide or inorganic hydroxide, MgSO ₄ , MgCl ₂ , CuSO ₄ , CaCl ₂ , CaSO ₄ , _{Al (SO 4) 2, Al} (SO 4) 2, MgSO 4 -xH 2 O, MgCl 2 -xH 2 O, CuSO 4 -xH 2 O, CaCl 2 -xH 2 O, CaSO 4 -xH 2 O and Al (SO ₄ ) _{2 -} x H ₂ O, and the like. Also, the thermochemical material may include silica gel, zeolite, and the like as a substance that adsorbs water.

For example, when heat radiation is required, the inorganic oxide is converted to an inorganic hydroxide by a chemical bond reaction with water, and the anhydrous salt is converted to a salt by the adsorption reaction with water, thereby releasing heat. For example, inorganic hydroxides can be converted into inorganic oxides by a chemical separation reaction with water when a heat storage is required, and a salt hydrate can absorb heat by being desorbed by desorption reaction with water.

The thermochemical material is capable of storing heat without heat loss because the heat absorbing and releasing reaction is made by a chemical reaction or an absorption / desorption reaction, If heat is required, it is possible to use partial heat dissipation by controlling the position or situation where the reaction occurs. Since these thermochemicals are difficult to transport through pipelines, they are effective when using a thermal delivery system that is transported to a heat consumer as a transportation means.

1 and 4, the reaction unit 100 may include a plurality of reaction units 100, and the plurality of reaction units 100 may be regularly arranged. For example, the reaction part 100 may be arranged in a lattice form.

When a heat radiation reaction occurs in the reaction part 100, a substance which reacts with the thermochemical substances is required to react thermochemical substances in the reaction part 100. The reaction part 200 includes a thermochemical material To the reaction part 100. In this case, As shown in the example of FIG. 1, in the case of the heat dissipation reaction, the supply unit 200 can supply materials for reacting the thermochemical substances of the reaction unit 100 by being connected to the plurality of reaction units 100, respectively. For example, the supply unit 200 may supply water, steam, or mist to the reaction unit 100 so that the thermochemicals react with each other.

When the thermal storage reaction occurs in the reaction unit 100, the supply unit 200 may be connected to each of the plurality of reaction units 100 to remove the materials separated from the thermochemical substances separately from the plurality of reaction units 100 . The material separated from the thermochemical material refers to a specific material among the materials generated in the thermal storage reaction. For example, since the thermal storage reaction is performed in the reaction part 100 at a temperature higher than the temperature at which the water boils, The separated material can be steam.

The opening and closing part 300 also serves to communicate the supplying part 200 and the reaction part 100. The opening and closing part 300 opens and closes the path between the reaction part 100 and the supplying part 200, It can play a role in regulating whether or not. For example, when the heat dissipation reaction occurs in the reaction part 100, the opening and closing part 300 is sequentially or simultaneously opened in accordance with the reaction sequence of the reaction part 100 to supply water or steam to the reaction part 100 from the supply part 200 . In addition, when the heat storage reaction occurs in the reaction part 100, for example, the opening and closing part 300 is sequentially or simultaneously opened in accordance with the heat storage order of the reaction part 100, and the steam generated in the reaction part 100 through the supply part 200 Can be removed.

The piping unit 400 is connected to the plurality of reaction units 100 to supply heat to the reaction unit 100 during heat storage through the fluid flowing in the piping unit 400, And absorb heat from the heat source. For example, the fluid may be water, air, steam, or the like.

The valve unit 500 may be located in the piping unit 400 and may control the flow of the fluid flowing through the piping unit 400. 1, the valve unit 500 opens and closes the piping unit 400 connecting the plurality of reaction units 100, flows through the piping unit 400 and performs heat exchange with the reaction unit 100 The flow of the fluid can be controlled.

1, the plurality of reaction units 100 may be regularly arranged in a lattice form, and the valve unit 500 may be disposed between the plurality of reaction units 100, The flow path of the fluid can be controlled so that the fluid flows only through the piping unit 400 connected to the reaction unit 100 which is disposed in the unit 100. For example, in the heat accumulation process, the reaction unit 100 to be heat-stored can be selected and stored. The controller controls the valve unit 500 to open only the piping unit 400 connected to the reaction unit 100 to regenerate the valve unit 500 so that the fluid flowing inside the piping unit 400 performs heat exchange only with the reaction unit 100 . ≪ / RTI > This is a characteristic feature of a heat storage device based on a thermochemical material which can store only a part of heat instead of accumulating heat in the entire reaction part 100, while it is impossible to store heat in a conventional sensible heat or phase change storage method when the amount of waste heat required for heat storage is insufficient.

4, the valve unit 500 is disposed between the plurality of reaction units 100, and is connected to the reaction unit 100 that radiates heat in the plurality of reaction units 100, The flow path of the fluid can be controlled so that the fluid flows only to the fluid channel 400. For example, the heat dissipation process can be performed by selecting only the reaction unit 100 to be heat dissipated. The controller may control the valve unit 500 to open only the piping unit 400 communicating with the reaction unit 100 for heat dissipation and perform heat exchange only with the reaction unit 100 that radiates the fluid flowing through the piping unit 400 .

The control unit (not shown) may control the supply unit 200, the opening and closing unit 300, the pipe unit 400, and the valve unit 500. For example, the control unit may control the amount or speed of the material supplied from the supplying unit 200 to the reaction unit 100. For example, the control unit can control the opening and closing of the opening and closing unit 300, and can control the amount and speed of the fluid flowing through the piping unit 400. Further, as described above, the control unit can control the flow path of the fluid flowing through the piping unit 400 by controlling the valve unit 500.

Hereinafter, a heat storage and heat dissipation method using a heat storage and heat dissipation device according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 5 is a flowchart of an embodiment of a heat storage method using a heat storage and heat dissipation device according to the present invention, and FIG. 6 is a flowchart of an embodiment of a heat dissipation method using the heat storage and heat dissipation device according to the present invention.

The heat storage method using the heat accumulating and dissipating device includes a path adjusting step S1 for adjusting the valve part 500 to select the flow path of the fluid flowing in the pipe part 400, And a storage step (S2) for allowing a fluid to flow into the piping part (400) positioned on the reaction part (100) so that a thermal storage reaction occurs in the reaction part (100). Also, the heat storage method includes a reaction part package manufacturing step S3 for manufacturing the reaction part 100 with a predetermined number of reaction part packages and a transfer step S4 for transferring the reaction part package to the heat consumer using the transportation part ).

The heat storage method using the heat accumulating and dissipating device described above is a path adjusting step of selecting the flow path of the fluid flowing in the pipe portion 400 by controlling the valve portion 500 through the control portion . In the step S1, when there is a plurality of reaction parts 100, the reaction part 100 to be heat-stored in the heat storage reaction is selected according to how much heat is dissipated by the reaction parts 100, Can be adjusted.

Next, in step S2, the valve unit 500 located on the fluid flow path selected in step S1 is opened, and the inside of the pipe unit 400 located on the fluid flow path selected in step S1 is opened And a heat storage reaction is performed in the reaction part (100) so that a fluid containing heat flows.

For example, in this step, the supply unit 200 may remove substances separated from the thermochemical substances separately from the plurality of reaction units 100. For example, since the thermal storage reaction is performed in the reaction part 100 at a temperature higher than the temperature at which the water boils, the material separated from the thermochemical material can be steam. For example, in this step, the opening and closing part 300 may be sequentially or simultaneously opened in accordance with the heat accumulation order of the reaction part 100 to remove the steam generated in the reaction part 100 through the supply part 200.

Next, step (S3) is a reaction part package manufacturing step for manufacturing the reaction part 100 as a plurality of reaction part packages. The plurality of reaction parts 100 that have been stored after storing the plurality of reaction parts 100 through the step S2 may be divided into a predetermined size so as to form a bundle of packages. For example, the reactor package can be combined into various sizes depending on the needs of the customer.

However, the step (S3) may be performed before the step (S1) or the step (S2).

Next, the step (S4) is a transfer step (S4) for transferring the reaction part package to the heat consumer using the transportation means. (S4) is a step of transferring the reaction part package to the heat consumer using the transportation means. The reaction part 100 accumulates heat through chemical reaction or desorption reaction, and the reaction is performed in the reaction part 100 So that heat loss is not generated in this step.

Next, the heat dissipation method will be described. In the heat dissipation method using the heat storage and heat dissipation device, a path adjustment step (S5) for selecting a flow path of the fluid flowing through the pipe part (400) A supply step S6 of supplying the material supplied from the supply part 200 to the reaction part 100 by adjusting the opening and closing part 300 so that a heat radiation reaction takes place in the reaction part 100 positioned on the flow path of the fluid selected in the step S6, A heat dissipation step S7 in which a heat dissipation reaction occurs in the reaction part 100 positioned on the flow path of the fluid selected in the path adjustment step, and a heat supply step S8 for supplying heat generated in the heat dissipation step to the heat consumer have.

The heat dissipation method using the heat accumulating and dissipating device described above is a path adjusting step of selecting a flow path of the fluid flowing in the piping part 400 by controlling the valve part 500 through the control part . For example, a heat demander has various requests for supply temperature, flow rate, and supply time. For this, in step S5, if there is a plurality of reaction parts 100, the reaction part 100 to be heat-released in the heat radiation reaction may be selected according to which reaction part 100 radiates heat and the heat radiation amount, have.

As shown in FIG. 4 (a), for example, when the heat demand of the heat consumer is detected and the temperature is low but a large amount of heat is required in a short time, the valve unit 500 is adjusted And a parallel step of connecting the piping parts 400 in parallel so that a large amount of flow flows through the piping part 400 in a plurality of flows which do not mix with each other in a certain section of the piping part 400. Referring to FIG. 4 (a), in this step, the valve unit 500 is controlled so as to block the fluid flow in the vertical direction in the drawing, so that the fluid flows only in the left and right directions in the drawing, Lt; / RTI >

As shown in FIG. 4 (b), for example, when the heat demand of the heat consumer is identified and the heat needs to be used at a low temperature for a long time, the valve unit 500 is controlled, And a series of steps of connecting the first and second units 400 and 400 in series so that the flow path of the fluid flowing in the pipe unit 400 connected to the reaction unit 100 for radiating heat is longer. Referring to FIG. 4 (b), in this step, the valve 500 is controlled so that the fluid flows through the piping unit 400 in one flow, unlike the case of FIG. 4 (a) So that it can be suitably used in a case where the temperature is low but needs to be used for a long time by allowing the reaction part 100 to pass through as few reactors as possible.

Referring to FIG. 4C, in this step, a large number of reaction parts 100 in which the fluid flowing inside the pipe part 400 is radiated by connecting the pipe part 400 in series by controlling the valve part 500 So that the flow rate is small but the fluid having the maximum temperature is required.

As shown in FIG. 4 (d), for example, the present step controls the valve unit 500 to determine the heat demand of the heat consumer, And closing the valve unit 500 located in the piping unit 400 passing through the valve unit 500. 4 (d), the valve portion 500 located in the piping portion 400 passing through the marked portion "X" may be blocked to prevent the fluid from flowing to the portion indicated by "X" . This is because when the fluid flows into the piping unit 400 connected to the reaction unit 100 in which the exothermic reaction does not occur, the fluid may move to the piping unit 400, .

In this way, by controlling the reaction unit 100 and the valve unit 500 through the path selection step, the fluid flow path can be adjusted to match the supply temperature, flow rate, and supply time required in the heat consumer.

Next, in operation S6, the opening / closing part 300 is controlled so that a heat dissipation reaction occurs in the reaction part 100 positioned on the fluid flow path selected in the step S5, (100). At this time, the control unit can adjust the amount or speed of the substance to be supplied to the reaction unit 100 by adjusting the supply unit 200 or the opening / closing unit 300.

Next, (S7) is a heat dissipation step in which a heat dissipation reaction occurs in the reaction part 100 positioned on the path selected in step (S5). For example, this step can generate heat by reacting thermochemical materials using the water supplied in step (S6).

Next, (S8) is a heat supply step for supplying the heat generated in the step (S7) to the heat consumer. In this step, the heat generated in the reaction part 100 is supplied to the heat consumer through the heat exchange between the fluid flowing in the piping part 400 communicated with the reaction part 100 where the heat dissipation reaction takes place and the reaction part 100 to be.

The present invention relates to a heat storage or heat dissipation device that uses thermal or latent heat to store heat or heat in a reaction part (100) by heat accumulation or heat dissipation through a chemical reaction, a desorption reaction, or an adsorption reaction using a thermochemical material, There is no loss, and the heat storage density is high, and the efficiency of heat storage and heat dissipation device is high.

In addition, in the case of transporting the heat storage device by the conventional transportation device, there is a cost associated with installation of excessive heat insulation in the transportation means and reduction of the size of heat storage device due to weight or volume of the heat insulation material. However, in the case of the present invention, Since there is no heat loss during transportation, only the minimum amount of insulation can be applied, which reduces the weight and volume, which is economically effective. That is, if heat is stored in the reaction part 100 and the reaction is interrupted, heat storage can be performed semi-permanently without heat loss.

The heat stored in the heat storage device due to the heat loss is lost, so that the heat storage device can not be used for separating the heat storage device, The control of the reaction of the thermochemical material and the control of the valve unit 500 can control the flow rate of the fluid, the supply time, and the supply temperature, and can be adjusted according to various needs of the customer.

It should be noted that the embodiments disclosed in the drawings are merely examples of specific examples for the purpose of understanding, and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
