Description

Technology Field

[0001] The present invention relates to a temperature and humidity control unit installed within a container that stores and uses energy using a battery, and more specifically, to a temperature and humidity control unit in which the unit is mounted in a receiving opening formed on one side of the container and is movable in the inward and outward directions so as not to protrude outside the container during transport, and after installation, the unit protrudes outside the container to form a cooling passage through which air can circulate inside the container, thereby enabling efficient utilization of the space inside the container even if the volume increases with the increase in the capacity of the unit. Background Technology

[0003] As the depletion of petroleum resources and the risks of nuclear energy become more prominent, interest in and research on renewable energy are increasing significantly. Along with this, the development of Energy Storage Systems (ESS) to utilize renewable energy sources such as solar power and wind power is becoming essential.

[0004] ESS stands for "Energy Storage System," which refers to an energy storage system. An ESS is a system that stores energy generated from the power grid and extracts it for use when needed later. ESS has the advantage of improving the stability of power supply and efficiently integrating renewable energy.

[0005] ESS can be implemented in various forms, one of which is an ESS container equipped with a storage unit (e.g., a battery) that stores energy inside the container. Such ESS containers have the advantages of being easy to move and transport, and easy to install.

[0006] On the other hand, the ESS is installed in a sealed installation space inside a container for efficient power storage or power supply, and the installation space is maintained within a set temperature and humidity range. If the installation space exceeds the set temperature, the ESS overheats, and if it falls below the set temperature, the power storage efficiency decreases.

[0007] Korean Registered Patent No. 10-0939281 discloses an energy-saving constant temperature and humidity chamber utilizing the introduction of outside air and a method for controlling the same. The aforementioned patent document discloses a technology in which, when the outside temperature is lower than the temperature of an installation space where a computer system or electronic product manufacturing equipment is installed, cold outside air is introduced into the installation space to lower the temperature of the installation space, and when the outside temperature is higher than the temperature of the installation space, cold air generated from the evaporator of a refrigeration cycle system equipped in the installation space is circulated into the installation space to lower the temperature of the installation space.

[0008] As such, it is important to control the temperature and humidity inside the container so that the ESS operates smoothly and efficiently. If the heat generated by the ESS increases, the capacity of the temperature and humidity control unit must be increased to cool it.

[0009] However, the ESS, which stores and outputs power within the limited space of the container, occupies most of the space, and consequently, the volume of the temperature and humidity control unit cannot be increased indefinitely. This is because if the volume of the temperature and humidity control unit increases, the volume of the ESS must decrease relatively, which leads to a decrease in power storage capacity.

[0010] In addition, since the cooling air discharged from the constant temperature and humidity unit must be properly spaced apart from the batteries in the ESS to effectively cool all batteries, the distance between the ESSs must be maintained at a certain level. As the separation distance between the constant temperature and humidity unit and the ESS must be secured, the volume of the constant temperature and humidity unit becomes more constrained.

[0011] Therefore, it is necessary to develop a temperature and humidity control unit that can increase the capacity of the unit installed inside the ESS container while efficiently cooling the ESS battery. Prior art literature

[0016] Another objective of the present invention is to provide a constant temperature and humidity unit equipped in an energy storage container that can protect the ESS by preventing rainwater and foreign substances from entering the container while enabling the constant temperature and humidity unit to be withdrawn or inserted from the container by placing a packing along the edge of the receiving opening.

[0018] Another objective of the present invention is to provide a constant temperature and humidity unit equipped in an energy storage container, wherein a fixing member surrounds the body of a adjusting bolt that penetrates both a first bracket and a second bracket simultaneously, and both ends of the fixing member come into contact with the first bracket and the second bracket, thereby preventing the adjusting bolt from rotating due to vibration during transport and transfer and thus preventing the constant temperature and humidity unit from being withdrawn. means of solving the problem

[0020] To achieve the above-mentioned purpose, the present invention relates to a temperature and humidity control device (300) that stores energy and controls the temperature and humidity of a container (100) in which an ESS is installed, wherein a receiving opening (110) of the size of the temperature and humidity control device (300) is formed on one side of the container (100) in which the ESS is installed; wherein the temperature and humidity control device (300) is mounted in the receiving opening (110) so that the outer surface (330) of the temperature and humidity control device (300) is always exposed to the outside of the container (100), and the position of the temperature and humidity control device (300) is varied by sliding inward or outward through the receiving opening (110); and the position of the temperature and humidity control device (300) during operation protrudes further outward from the container (100) than the position of the temperature and humidity control device (300) during the transfer of the container (100).

[0022] In addition, the constant temperature and humidity device (300) of the present invention is positioned inside the container (100) when the container (100) is transported, so that the side wall (130) of the container (100) and the outer surface (330) of the constant temperature and humidity device (300) are on the same plane, and the two side surfaces (340) and the inner surface (320) of the constant temperature and humidity device (300) are positioned inside the container (100); when the constant temperature and humidity device (300) is operated, it is moved to the outside of the container (100), and the outer surface (330) of the constant temperature and humidity device (300) protrudes outwardly from the side wall (130) of the container (100), so that the cooling passage (d), which is the space between the inner surface (320) of the constant temperature and humidity device (320) and the ESS battery (200) positioned inside the container (100), is widened.

[0023] In addition, the present invention comprises: a first bracket (120) coupled to the side wall (130) of the container (100) and having a first bolt hole (121) formed on one side; a second bracket (310) coupled to both sides (340) of the constant temperature and humidity unit (300), having a second bolt hole (311) formed on one side, wherein the second bolt hole (311) is positioned opposite to the first bolt hole (121); and an adjustment bolt (400) that simultaneously penetrates the first bolt hole (121) and the second bolt hole (311), wherein the head portion (410) is in surface contact with the first bracket (120) and adjusts the distance of the cooling passage (d) while rotating in forward and reverse directions.

[0024] In addition, when the adjustment bolt (400) of the present invention is rotated forward, the temperature and humidity control unit (300) is withdrawn to the outside of the container (100), and the volume (V1) occupied by the temperature and humidity control unit (300) inside the container (100) decreases, and the volume (V2) occupied by the temperature and humidity control unit (300) outside the container (100) increases; when the temperature and humidity control unit (300) is withdrawn to the maximum, the second bracket (310) contacts the first bracket (120), and the volume (V1) occupied by the temperature and humidity control unit (300) inside the container (100) becomes the minimum, and the distance of the cooling passage (d) becomes the maximum.

[0025] In addition, when the adjustment bolt (400) of the present invention is rotated in reverse, the temperature and humidity control unit (300) moves into the interior of the container (100), and the volume (V1) occupied by the temperature and humidity control unit (300) inside the container (100) increases, and the volume (V2) occupied by the temperature and humidity control unit (300) outside the container (100) decreases; when the temperature and humidity control unit (300) moves inward to the maximum extent, the outer surface (330) of the temperature and humidity control unit (300) and the side wall (130) of the container (100) lie on the same plane, and the volume (V2) occupied by the temperature and humidity control unit (300) outside the container (100) becomes 0.

[0026] In addition, the present invention further includes a fixing member (430) formed in a cylindrical shape with a hollow center, having a slit (431) formed on the side through which the body portion (420) of the adjustment bolt (400) passes, and which surrounds the body portion (420) of the adjustment bolt (400) and has both ends in contact with the first bracket (120) and the second bracket (310), respectively.

[0027] In addition, the present invention further includes a rail provided on the side or bottom surface of the constant temperature and humidity unit (300) and guiding the movement of the constant temperature and humidity unit (300) by the forward and reverse rotation of the adjustment bolt (400).

[0028] In addition, the cooling passage (d) of the present invention is longer when the temperature and humidity control unit (300) is in operation than when the container (100) is being transported. Effects of the invention

[0030] The constant temperature and humidity device provided in the energy storage container according to the present invention forms a receiving opening of a certain size on one side of the container in which an ESS is mounted and mounts the constant temperature and humidity device in the receiving opening, and by providing the constant temperature and humidity device so that it can move inward and outward through the receiving opening, the cooling passage for cooling the ESS battery inside the container can be expanded, thereby improving cooling efficiency.

[0031] In addition, the present invention allows for safe transportation while complying with standard specifications for transportation and transfer by inserting a temperature and humidity control unit into the inside of the container so that it does not protrude outside the container when transporting and transferring an energy storage container. Furthermore, by protruding the temperature and humidity control unit outside the container after installing the energy storage container, the space occupied inside the container is drastically reduced, thereby enabling efficient utilization of the space inside the container.

Specific details for implementing the invention

[0037] Hereinafter, preferred embodiments of the present invention are described with reference to the accompanying drawings so that those skilled in the art can easily implement them.

[0039] As illustrated in FIGS. 1 to 7, the constant temperature and humidity device provided in the energy storage container according to the present invention is a device that maintains the temperature and humidity inside the container (100) at a constant level to protect and cool the ESS battery (200).

[0040] In a constant temperature and humidity device (300) that stores energy and controls the temperature and humidity of a container (100) in which an ESS is installed,

[0041] A receiving opening (110) the size of the constant temperature and humidity device (300) is formed on one side of the container (100) where the ESS is installed;

[0042] A temperature and humidity control unit (300) is mounted in the above-mentioned receiving port (110), so that the outer surface (330) of the temperature and humidity control unit (300) is always exposed to the outside of the container (100), and the position of the temperature and humidity control unit (300) is varied by sliding through the receiving port (110) to the inside or outside of the container (100);

[0043] The position of the operating temperature and humidity control unit (300) protrudes further outward from the container (100) than the position of the temperature and humidity control unit (300) when transporting the container (100).

[0045] ESS stands for Energy Storage System, which is a system equipped to store energy internally and use it when needed. Although the ESS can store various forms of energy, in one embodiment of the present invention, the storage and use of electrical energy using a battery (200) is described as an example.

[0046] The above ESS stores energy that is overproduced during periods of low demand in the power grid, and then supplies the energy stored in the ESS during periods when power demand surges and the power grid's supply alone cannot handle it, thereby supplementing the insufficient supply of the power grid.

[0047] In addition, renewable energy sources such as solar and wind power, which are heavily influenced by the natural environment, can be stored in the ESS in advance and used when needed, allowing for more flexible utilization of energy produced from the renewable power grid.

[0048] In order to transport and install such an ESS more easily and conveniently, the ESS equipment is equipped inside a container (100) and takes the form of a modular structure. Such an energy storage container (100) has the advantage of being easily transported and carried due to its convenient mobility.

[0049] The ESS inside the container (100) generates heat during use after installation, causing the temperature inside the container (100) to rise. Since high temperature and humidity have an adverse effect on the ESS, a cooling device is required. Therefore, a temperature and humidity control unit (300) is installed inside the container (100) to control the temperature and humidity inside the container (100), thereby creating an air conditioner that allows the ESS to operate more smoothly. The temperature and humidity control unit (300) is placed inside the container (100) to cool the ESS inside the container (100). It is desirable that the unit be equipped with a cooling capacity sufficient to cool the ESS in response to the amount of heat generated by the ESS. Generally, increasing the cooling capacity increases the volume of the temperature and humidity control unit (300).

[0050] However, since the container (100) is formed according to the specifications defined by the International Organization for Standardization (ISO) for efficient handling in various means of transportation and logistics systems such as ships and trucks, the volume of the temperature and humidity control unit (300) cannot be increased indefinitely to increase cooling capacity within the limited internal space of the container (100). Since the internal space of the container (100) occupies more than a certain level for the storage and processing of a large amount of energy in the ESS, and the temperature and humidity control unit (300) must form a cooling passage (d) by creating a gap between the ESS facilities in order to efficiently cool the entire area rather than a local area of ​​the ESS, the volume of the temperature and humidity control unit (300) is limited.

[0051] The present invention is intended to resolve the constraints on volume increase of a constant temperature and humidity device (300) mounted inside an energy storage container (100). A receiving opening (110) corresponding to the size of the constant temperature and humidity device (300) is formed on one side of the container (100), and the constant temperature and humidity device (300) is inserted into the receiving opening (110), provided that the constant temperature and humidity device (300) slides within the receiving opening (110). As the constant temperature and humidity device (300) moves inward or outward within the container (100), the space (volume) occupied by the constant temperature and humidity device (300) inside the container (100) can be varied.

[0052] When transporting and moving the energy storage container (100), the ESS equipment does not operate, so there is no need to cool it as it does not generate heat. Therefore, the constant temperature and humidity unit (300) is not operated and is inserted into the container (100) so that it does not protrude outside the container (100), so there is no obstruction during transport and moving and there is less risk of damage.

[0053] After the energy storage container (100) is transported and installed, and the ESS begins to operate, heat is generated in the ESS and must be cooled. Therefore, to ensure effective cooling, a temperature and humidity control unit (300) is slightly extended outside the container (100) to form a cooling passage (d), which is the space between the ESS equipment and the temperature and humidity control unit (300). At this time, a part of the temperature and humidity control unit (300) protrudes outside the container (100), but since the container (100) is fixed and installed in one place, there is no risk of it getting caught or damaged.

[0054] In this way, even if the volume increases to increase the cooling capacity of the constant temperature and humidity unit (300), when operating after installing the energy storage container (100), the constant temperature and humidity unit (300) can be pulled out slightly outside the container (100) to secure a cooling passage (d), and when transporting and carrying the container (100), the constant temperature and humidity unit (300) can be inserted into the container (100) so as not to protrude outside the container (100) to provide convenient mobility.

[0055] Therefore, the constant temperature and humidity unit provided in the energy storage container according to the present invention has the advantage of having a larger cooling capacity while effectively cooling the entire area of ​​the ESS facility inside the container (100).

[0057] As illustrated in FIGS. 1 to 3, the ESS facility according to the present invention is provided within a container (100) to facilitate the transport and installation of related facilities. This container (100) is referred to as an energy storage container (100) or simply a container (100). Although the facility constituting the ESS includes various components that perform functions such as energy storage, output, and control, only the battery (200), which occupies a large volume, is illustrated in the drawings according to an embodiment of the present invention. However, this does not mean that other components constituting the ESS are excluded, and that they are simply omitted from illustration. The container (100) can be transported overseas via a ship.

[0059] Referring to FIG. 1, in the present invention, the inner direction means a direction toward the center of the container (100), and the outer direction means a direction toward the outside of the container (100), opposite to the inner direction.

[0060] As shown in the drawing, when transporting and carrying the energy storage container (100) of the present invention, the temperature and humidity control unit (300) slides inwardly in the container (100) so as not to protrude outwardly, and when the energy storage container (100) is installed and operated after transport and carrying is completed, the temperature and humidity control unit (300) slides outwardly in the container (100) so that part or all of the temperature and humidity control unit (300) protrudes outwardly from the outside of the container (100), that is, from the outer surface (330) of the container (100).

[0062] Referring to FIG. 3, the container (100) can be formed in various standard sizes. A battery (200), which is one of the ESS facilities, is placed inside the container (100) manufactured in such a standard size. In the present invention, the battery (200) is referred to as a battery (200) provided in various forms such as a cell, module, or pack, and for convenience of explanation, it is simply referred to as a 'battery (200)'.

[0063] According to one embodiment of the present invention, the battery (200) is provided in multiple numbers and arranged, and the arrangement direction is the longitudinal direction of the container (100). At this time, the longitudinal direction refers to the direction of the corner that is 6.058m in a 20-foot standard container specified by ISO.

[0064] There is a slight gap between the batteries (200) for cooling, and the gap becomes a passage through which cooling air flows into the batteries (200) and heat-generating air is discharged from the batteries (200).

[0065] The side wall (130) of the above container (100) refers to a wall that separates the interior and exterior of the container (100).

[0067] In the present invention, the movement of a container (100) for the purpose of transport is expressed as 'transport,' and the movement of a temperature and humidity control unit (300) relative to a receiving port (110) is expressed as 'sliding movement' or 'movement.' When the container (100) is 'transported,' the temperature and humidity control unit (300) is also transported together with the container (100), but since it does not move relative to the receiving port (110), it is not '(sliding) moved.'

[0069] In addition, power supply to the ESS and operation is expressed as 'operation,' and the constant temperature and humidity unit (300) being operated for cooling or dehumidification is expressed as 'operation.' The phrase 'when the constant temperature and humidity unit (300) is operated' also includes the meaning of 'when the container (100) is transported to the site and installed on-site.'

[0071] As shown in FIG. 2, a receiving opening (110) corresponding to the size of the constant temperature and humidity device (300) is formed on one side of the container (100). The receiving opening (110) is a passage through which the constant temperature and humidity device (300) moves inward and outward from the container (100).

[0072] A packing (111) is provided at the edge of the above-mentioned receiving hole (110) to prevent water, foreign substances, etc. from entering the container (100) through the gap between the edge of the receiving hole (110) and the two sides (340) of the constant temperature and humidity unit (300). The packing (111) fills the gap between the edge of the receiving hole (110) and the two sides (340) of the constant temperature and humidity unit (300), thereby preventing cold air inside the container (100) from leaking out to the outside and blocking rainwater, foreign substances, etc. from outside the container (100) from entering the container (100).

[0073] The above temperature and humidity control unit (300) moves variably to the inside and outside of the container (100), and the two sides (340) slide while in contact with the packing (111), so that no gap occurs between the two sides (340) of the temperature and humidity control unit (300) and the packing (111).

[0075] Referring to FIG. 2, the constant temperature and humidity unit (300) fitted into the receiving port (110) is an air conditioner that controls the temperature and humidity inside the container (100) to a range where the ESS can operate smoothly. Although the constant temperature and humidity unit (300) according to one embodiment of the present invention is shown with an outer surface formed as a cuboid, it can also be formed in various shapes.

[0076] In the constant temperature and humidity device (300), the side facing the inside of the container (100) is referred to as the inner surface (320), the side facing the outside is referred to as the outer surface (330), and the left and right sides are referred to as the two-sided sides (340). The two-sided sides (340) are surfaces that come into contact with the packing (111) fitted into the receiving hole (110), and are the left and right sides when the outer surface (330) is viewed from the front.

[0077] The above temperature and humidity control unit (300) has an inlet / outlet for air from inside and outside the container (100) to enter and exit, and a discharge port for discharging cold air from the temperature and humidity control unit (300) is formed on the inner surface (320). The discharge port on the inner surface (320) supplies cold air toward the ESS battery (200) to suppress heat generation in the ESS.

[0078] The outer surface (330) may have an outlet formed therein for discharging hot air to the outside of the container (100). Regardless of whether the temperature and humidity control unit (300) moves inward or outward, the outer surface (330) is always exposed to the outside of the container (100). It is obvious, as shown in FIGS. 1 and 6, that the outer surface (330) is exposed when the temperature and humidity control unit (300) moves outward, and even when the temperature and humidity control unit (300) moves completely inward, the outer surface (330) is exposed to the outside, as shown in FIG. 7.

[0079] The above constant temperature and humidity device (300) can be slid inward or outward so that its position can be varied.

[0080] Depending on whether the energy storage container (100) is transported and installed, the position of the constant temperature and humidity unit (300) inside the container (100) is arranged in various ways.

[0081] During the process of transporting and carrying the energy storage container (100), the temperature and humidity control unit (300) moves into the interior of the container (100), and the outer surface (330) does not protrude further than the side wall (130) of the container (100). More preferably, the outer surface (330) of the temperature and humidity control unit (300) and the side wall (130) of the container (100) are placed on the same plane as shown in FIG. 7. At this time, it is desirable for the inner surface (320) and the battery (200) to be in contact so that there is no cooling passage (d), as this allows the volume to increase to increase the cooling capacity of the temperature and humidity control unit (300), but a cooling passage (d) may be formed at a minimum level. In the present invention, when the container (100) is transported, it is assumed that the position of the temperature and humidity control unit (300) has completely moved into the interior as shown in FIG. 7.

[0082] After the energy storage container (100) has been transported and installed, the temperature and humidity control unit (300) is slid to protrude further outward than the side wall (130) of the container (100). When the temperature and humidity control unit (300) is operated in the present invention, the installation of the container (100) is completed, and the temperature and humidity control unit (300) is slid outward from the container (100) so that the outer surface (330) of the temperature and humidity control unit (300) protrudes further outward than the side wall (130) as in FIG. 1 or FIG. 7. The protruding length is maximized so that the cooling passage (d) is maximized and the cooling efficiency is increased, but it may vary depending on the environment and conditions.

[0083] Therefore, when the temperature and humidity control unit (300) is in operation, the container (100) is not being transported but is in a state where installation is complete, so the position of the temperature and humidity control unit (300) protrudes further outward from the container (100) than the position of the temperature and humidity control unit (300) when the container (100) is being transported.

[0084] For convenience of explanation, as illustrated in FIGS. 3, 6, and 7, the volume of the constant temperature and humidity unit (300) itself is referred to as 'V', the volume occupied by the constant temperature and humidity unit (300) in the internal space of the container (100) is referred to as 'V1', and the volume occupied in the external space of the container (100) is referred to as 'V2'. When the thickness of the container (100) is ignored, the sum of the volume (V1) occupied in the internal space of the container (100) and the volume (V2) occupied in the external space of the container (100) is equal to the volume (V) of the constant temperature and humidity unit (300).

[0085] The present invention increases the cooling capacity by maximizing the volume (V) of the constant temperature and humidity unit (300), while minimizing the volume (V1) occupied inside the container (100), thereby allowing a large capacity battery (200) to be installed inside the container (100) and effectively cooling the battery (200) by forming a cooling passage (d).

[0086] To this end, the constant temperature and humidity device (300) is not fixed inside the container (100), but slides inward and outward through the receiving opening (110) to minimize the volume (V1) occupied inside the container (100).

[0087] When the installation of the container (100) is completed and the temperature and humidity control unit (300) is slid outward from the container (100) to operate the temperature and humidity control unit (300), the cooling passage (d), which is a space separated from the inner surface (320) of the temperature and humidity control unit (300) and the battery (200), widens. If the battery (200) is too close to the inner surface (320), which is the surface from which cold air is discharged from the temperature and humidity control unit (300), it becomes difficult for the cold air to spread to the entire area of ​​the ESS, and the cold air reaches only the local area adjacent to the inner surface (320) to cool, so the ESS in the area where the cold air does not reach is not cooled, and there is a risk of malfunction.

[0088] Therefore, as the temperature and humidity control unit (300) slides outward (withdrawn), the cooling passage (d) is sufficiently secured between the inner surface (320) from which cold air is discharged and the battery (200), so that cold air can be diffused throughout the entire area of ​​the ESS and effectively cooled.

[0089] As the above-mentioned constant temperature and humidity unit (300) moves to the inside and outside of the container (100), the space of the cooling passage (d) increases or decreases, and even if the volume of the constant temperature and humidity unit (300) increases (cooling capacity increases) so that the distance (cooling passage (d)) between the inner surface (320) of the constant temperature and humidity unit (300) and the battery (200) converges to 0, the cooling passage (d) can be secured by withdrawing the constant temperature and humidity unit (300).

[0090] For cooling the ESS facility, space between the batteries (200) and the space between the side wall (130) of the container (100) and the batteries (200) must also be secured. In the present invention, it is assumed that space between the batteries (200) and the space between the side wall (130) of the container (100) and the batteries (200) are secured, and the cooling passage (d) is used to mean the space between the inner surface (320) and the batteries (200).

[0092] As shown in FIGS. 2 to 5, a first bracket (120), a second bracket (310), and an adjustment bolt (400) are provided to allow the temperature and humidity control unit (300) to slide more smoothly within the receiving port (110). The first bracket (120), the second bracket (310), and the adjustment bolt (400) may be provided in multiple numbers and placed in various locations.

[0093] The first bracket (120) is a bracket that is coupled to the side wall (130) of the container (100), and a first bolt hole (121) is formed on one side. The second bracket (310) is a bracket that is coupled to both sides (340) of the constant temperature and humidity unit (300), but it may also be coupled to a side other than the two sides (340). A second bolt hole (311) is formed on one side of the second bracket (310). The first bolt hole (121) and the second bolt hole (311) are arranged facing each other, and an adjustment bolt (400) passes through the first bolt hole (121) and the second bolt hole (311) simultaneously.

[0094] The head portion (410) of the above adjustment bolt (400) is formed to be larger than the first bolt hole (121) and the second bolt hole (311) so as not to penetrate, and the body portion (420) penetrates the first bolt hole (121) and the second bolt hole (311).

[0095] The above adjustment bolt (400) is fixed to one of the first bracket (120) and the second bracket (310), and the bracket not fixed to the adjustment bolt (400) moves along the longitudinal direction of the adjustment bolt (400) according to the forward and reverse rotation of the adjustment bolt (400).

[0096] Since the first bracket (120) is connected to the container (100) and the second bracket (310) is connected to the constant temperature and humidity unit (300), the constant temperature and humidity unit (300) slides along the receiving opening (110) of the container (100) according to the forward and reverse rotation of the adjustment bolt (400).

[0097] In one embodiment of the present invention, the head portion (410) of the adjustment bolt (400) is in surface contact with the first bracket (120) and is rotatably fixed to the first bracket (120). As the adjustment bolt (400) rotates, the second bolt hole (311) of the second bracket (310) moves along the threads of the adjustment bolt (400), and the constant temperature and humidity unit (300) slides to adjust the distance of the cooling passage (d).

[0098] When the forward rotation of the adjustment bolt (400) moves the temperature and humidity control unit (300) outward, the volume (V1) occupied by the temperature and humidity control unit (300) in the internal space of the container (100) gradually decreases, and the volume (V2) occupied by the temperature and humidity control unit (300) in the external space of the container (100) increases. When the volume (V2) occupied by the temperature and humidity control unit (300) in the external space of the container (100) is formed to the maximum, the two sides (340) and the inner surface (320) of the temperature and humidity control unit (300) are positioned inside the container (100), and the outer surface (330) is on the same plane as the side wall (130) of the container (100). At this time, the volume (V1) occupied by the constant temperature and humidity device (300) inside the container (100) becomes a minimum that converges to 0, the second bracket (310) comes into contact with the first bracket (120), and the distance of the cooling passage (d) becomes a maximum.

[0099] When the adjustment bolt (400) rotates in the reverse direction and the temperature and humidity control unit (300) moves inward, the volume (V1) occupied by the temperature and humidity control unit (300) in the internal space of the container (100) gradually increases, and the volume (V2) occupied by the temperature and humidity control unit (300) in the external space of the container (100) decreases. When the temperature and humidity control unit (300) moves inward to the maximum extent, the outer surface (330) of the temperature and humidity control unit (300) is placed on the same plane as the side wall (130) of the container (100), and the volume (V2) occupied by the temperature and humidity control unit (300) outside the container (100) converges to 0. At this time, in order to increase the cooling capacity of the constant temperature and humidity unit (300), it is desirable to increase the volume of the cooling passage (d), which is the space between the constant temperature and humidity unit (300) and the battery (200), so that it is formed to a minimum.

[0100] Therefore, when transporting the container (100), the temperature and humidity control unit (300) is moved to the inside of the container (100), so the cooling passage (d) becomes minimal, and when operating the temperature and humidity control unit (300), the temperature and humidity control unit (300) is moved to the outside of the container (100), so the cooling passage (d) becomes maximum, so the cooling passage (d) is formed to be longer when operating the temperature and humidity control unit (300) than when transporting the container (100).

[0101] After moving the above temperature and humidity control unit (300), a fixing member (430) is fitted into the body portion (420) of the adjustment bolt (400) to fix it in the moved position. The fixing member (430) is formed in a cylindrical shape, with a slit (431) formed on the side through which the body portion (420) passes, and the center is formed hollow so that the body portion (420) is inserted.

[0102] When the body part (420) is inserted into the hollow center through the slit (431), the fixing member (430) is positioned between the first bracket (120) and the second bracket (310), and both ends of the fixing member (430) are in contact with the first bracket (120) and the second bracket (310), respectively. Therefore, even if the temperature and humidity control unit (300) attempts to move in a direction where the first bracket (120) and the second bracket (310) are closer, the fixing member (430) prevents this, so the temperature and humidity control unit (300) is fixed. Thus, it prevents the adjustment bolt (400) from rotating and moving the temperature and humidity control unit (300) due to vibrations occurring in the container (100) or transmitted from the outside.

[0103] When the above temperature and humidity control unit (300) moves inward or outward, a rail (not shown) may be further provided on the bottom or side of the temperature and humidity control unit (300) to guide the movement of the temperature and humidity control unit (300) by forming a length inward or outward. Since the temperature and humidity control unit (300) moves along the rail, friction and rolling resistance are reduced, and the temperature and humidity control unit (300) can be moved more easily and conveniently.

[0104] In the present invention, an adjustment bolt (400) is used as an example to move the temperature and humidity control unit (300) from the receiving port (110), but it is not limited thereto. When a rail is formed on the bottom surface of the temperature and humidity control unit (300), the position of the temperature and humidity control unit (300) can be adjusted manually by pushing or pulling, or by using a lever-type lever that presses the temperature and humidity control unit (300) in the inner or outer direction, and various methods other than a fixing bracket (430) can be used to fix the moved position.

[0106] In addition, according to one embodiment of the present invention, a container (100) is formed with an open receiving opening (110) on a side wall (130) and a constant temperature and humidity device (300) is fitted into the receiving opening (110). However, as another embodiment, as shown in FIG. 8, a door (140) capable of opening and closing the inside and outside of the container is provided, and a constant temperature and humidity device (300) may be provided in the door (140).

[0107] In the above door (140), a receiving opening (110) is formed so that the temperature and humidity control unit (300) can be exposed to the outside of the container (100), and the temperature and humidity control unit (300) is fitted therein. Although not shown in the drawing, a packing (111) may be further provided along the edge of the groove.

[0108] A second bracket (310) is provided in the constant temperature and humidity unit (300), and a first bracket (120) is provided in the door (140) of the container (100). An adjustment bolt (400) penetrating the first bracket (120) and the second bracket (310) can move the constant temperature and humidity unit (300). At this time, the head portion (410) of the adjustment bolt (400) is located in the inner direction of the container (100), and the body portion (420) can be exposed to the outside of the container (100).

[0109] When the door of the container (100) is opened, the temperature and humidity control unit (300) also moves along the door (140) as shown in FIG. 8, and when the door is closed, the temperature and humidity control unit (300) also moves to a position as shown in FIG. 9 and FIG. 10. FIG. 9 shows the operation of the temperature and humidity control unit (300) in the container (100) equipped with the door (140), and FIG. 10 shows the state of the container (100) equipped with the door (140) during transport.

[0111] The constant temperature and humidity unit provided in the energy storage container according to the present invention can be formed with a large volume to increase cooling capacity. For example, when the outer surface (330) of the constant temperature and humidity unit (300) is placed on the same plane as the side wall (130) of the container (100), the inner surface (320) can be formed with a volume that is very close to the battery (200) of the ESS. In this case, the cooling passage (d) is close to 0, but when the energy storage container (100) is installed and operation begins, the constant temperature and humidity unit (300) can be pulled out to the outside to expand the cooling passage (d) to a space where the cold air can sufficiently spread, so that when designing the maximum volume of the constant temperature and humidity unit (300), the space for the cooling passage (d) does not need to be considered.

[0112] In order to store and process high-level energy, even if a large amount of heat is generated in the ESS, the volume can be increased so that the cooling capacity of the constant temperature and humidity unit (300) can reach a target value. Explanation of the symbols
