[0135] It can be interpreted as including the tea range.

[0136] (Example 1-1) An invention according to one embodiment of the present invention is to use cold heat from LNG.

[0137] Specifically, for a cooling system, LNG and refrigerant exchange heat energy.

[0138] is a heat exchange unit (100); a first inlet pipe (210) that introduces internal air into the data center and an external air

[0139] A second inlet pipe (220) for introducing air is provided, and the first inlet pipe (210) and the second inlet pipe

[0140] (220) Air conditioning unit (200) where mixed air introduced into the unit exchanges heat energy with the refrigerant;

[0141] After heat energy exchange is performed in the above heat exchange unit (100), the heat exchange unit (100)

[0142] A first refrigerant transfer pipe (310) that transfers the refrigerant to the air conditioning unit (200); and the heat exchange unit

[0143] Before heat energy exchange occurs in (100), the heat exchange in the air conditioning unit (200)

[0144] It includes a second refrigerant transfer pipe (320) for transferring the refrigerant to the part (100).

[0145] Referring to Figure 1, the present invention is a cooling system using the cold heat of LNG,

[0146] The heat exchange unit (100), the air conditioning unit (200), the first refrigerant transfer pipe (310), and the second refrigerant transfer pipe (320) are

[0147] It can be included in the original.

[0148] The heat exchange unit (100) may be configured to exchange heat between LNG and refrigerant.

[0149] The refrigerant is transferred through the first refrigerant transfer pipe (310) and the second refrigerant transfer pipe (320) before and after heat exchange.

[0150] It can be moved.

[0151] In the heat exchange unit (100), the temperature of LNG increases before and after heat exchange.

[0152] Refrigerants, on the other hand, can lower the temperature.

[0153] (Example 2-1) In Example 1-1, the first refrigerant transfer pipe (310) and the

[0154] It includes a pressure regulator (315) that changes the pressure of the refrigerant to a set pressure.

[0155] (Example 2-2) In Example 2-1, the pressure regulator (315) is

[0156] Temperature range of the refrigerant before and after heat energy exchange occurs in the air conditioning unit (200)

[0157] The above set pressure is set so that the refrigerant undergoes a phase change.

[0158] The first refrigerant transfer pipe (310) supplies refrigerant whose temperature has decreased in the heat exchange unit (100).

[0159] It may be a configuration that is transferred to the keynote speaker (200).

[0160] It is connected to the first refrigerant transfer pipe (310) and adjusts the pressure of the refrigerant being transferred.

[0161] A pressure regulator (315) may be included.

[0162] The pressure regulator (315) controls the refrigerant moving through the first refrigerant moving pipe (310) and the second refrigerant moving pipe (315).

[0163] The temperature of the refrigerant moving through the condenser (320) is the pressure at which the refrigerant becomes liquid and gas, respectively.

[0164] It may be a configuration that applies force to the refrigerant.

[0165] If the refrigerant becomes a liquid, when it flows through the refrigerant pipe, the cross section of the refrigerant pipe

[0166] Even if the enemy's back is designed to be relatively small, sufficient refrigerant can be transported.

[0167] In addition, the temperature of the refrigerant decreases in the heat exchange unit (100), and the air conditioning unit

[0168] (200) can go through a process of temperature increase.

[0169] In the air conditioning unit (200), the refrigerant extracts heat energy from the internal air of the data center.

[0170] It acts as an absorber, that is, in the direction of lowering the internal temperature of the data center.

[0171] Refrigerants can be utilized.

[0172] The temperature change process of the refrigerant involves the state of the refrigerant changing from liquid to gas.

[0173] A process of refrigeration change may be involved. For this purpose, the pressure of the refrigerant needs to be adjusted appropriately.

[0174] , and the present invention may further include a pressure regulator (315) for this purpose.

[0175] If the state change process of the refrigerant is included, in one refrigerant circulation cycle

[0176] The amount of heat energy that can be transferred per mass of refrigerant can be significantly increased.

[0177] In other words, only the sensible heat energy of the refrigerant is used to transfer heat energy.

[0178] No, by utilizing the latent heat section of the refrigerant, latent heat energy can be used to transfer heat energy.

[0179] there is.

[0180] (Example 3-1) In Example 2-1, the heat exchanger (100) is a shell-and-tube

[0181] In this way, heat energy exchange between the LNG and the refrigerant takes place.

[0182] The heat exchanger (100) can be formed in a shell-and-tube manner.

[0183] The shell-and-tube method can be seen in Figure 2. LNG flows through the tube.

[0184] As the refrigerant moves outside of such tubes, it passes through as much surface area of ​​the tubes as possible.

[0185] This refers to the structure in which heat exchange takes place.

[0186] (Example 3-2) In Example 2-1, LNG is supplied to the heat exchange unit (100).

[0187] The first LNG transfer pipe (110) is in a hurry; heat energy is exchanged with the refrigerant in the heat exchange unit (100).

[0188] It includes a second LNG transfer pipe (120) that discharges the LNG that has occurred.

[0189] An invention according to an exemplary embodiment of the present invention is a heat exchange unit (100) for LNG

[0190] The refrigerant and heat energy are exchanged in the first LNG transfer pipe (110) and heat exchanger (100).

[0191] After that, it may include a second LNG transfer pipe (120) that discharges LNG with an increased temperature. The second

[0192] The temperature of LNG discharged from the heat exchanger (100) through the LNG transfer pipe (120) is equal to that of city gas.

[0193] It may still be too low to connect to a pipeline to generate electricity. Therefore, the second LNG transfer

[0194] After more practically utilizing the cold energy of LNG discharged from the pipe (120), it is transferred to the city gas pipeline.

[0195] Can supply.

[0196] In this way, low-temperature LNG undergoes heat exchange with the refrigerant once more.

[0197] It can be supplied through city gas pipelines.

[0198] (Example 4-1) In Example 2-1, the air conditioning unit (200) is a foreign substance

[0199] A filter (230) that filters out heat energy between the mixed air and the refrigerant;

[0200] Heat exchanger (240);, humidifier (250) that generates and discharges water vapor;, flow of the mixed air

[0201] It includes a blower (260) that controls the .

[0202] Referring to Figure 3, in an exemplary embodiment of the present invention, an air conditioning unit

[0203] (200) may include a filter (230), a heat exchanger (240), a humidifier (250), and a blower (260).

[0204] The filter (230) may be configured to remove foreign substances flowing into the mixed air.

[0205] Ventilation (240) may be a configuration in which mixed air and refrigerant exchange heat energy. Generally,

[0206] The temperature of the mixed air is higher than that of the refrigerant, and therefore the temperature of the mixed air can be reduced.

[0207] The mixed air with reduced temperature is returned to the data center and through its circulation process, the data is

[0208] The temperature of the data center remains constant despite the heat emitted from the data servers.

[0209] You can do it.

[0210] The humidifier (250) may be configured to control the humidity in the data center.

[0211] , and may be a composition that generates and releases moisture.

[0212] In addition, the blower (260) is designed to mix air as intended by the designer and to

[0213] (200) A device for introducing mixed air that has been introduced and heat exchanged into the data center.

[0214] It can be a surname. It can be formed as a fan in general.

[0215] (Example 4-2) In Example 4-1, the second inlet pipe (220) is optional.

[0216] It includes an external opening / closing device (221) that can be opened / closed.

[0217] The second inlet pipe (220) is a pipe that introduces outside air into the air conditioning unit (200).

[0218] However, in the operation of the air conditioning unit (200), outside air is essential.

[0219] No. The internal air of the data center is drawn in from the first inlet pipe (210) and its temperature is

[0220] Just by lowering it and sending it back to the data center, we can lower the temperature of the data center.

[0221] The intended purpose of the present invention can be achieved.

[0222] Therefore, an external opening / closing device that can selectively open / close the second inlet pipe (220)

[0223] It may further include teeth (221).

[0224] In addition, the external switch (221) is used when the internal pressure of the data center is higher than the reference pressure.

[0225] If it is high, it can be closed, otherwise it can be kept open.

[0226] The auxiliary opening device (221) can be formed as a solenoid valve.

[0227] The internal pressure of the data center is released to the data server through the external switch (221).

[0228] It can prevent excessive temperature rise due to overheating of the back.

[0229] (Example 4-3) In Example 4-1, the heat exchanger (240) is the cold

[0230] It includes a cooling coil (241) in which each fluid flows, and heat energy is exchanged in the cooling coil (241).

[0231] After the exchange occurs, the cooled air is supplied to the lower part of the data center.

[0232] In an exemplary embodiment of the present invention, the heat exchanger (240) comprises a cooling coil

[0233] (241) and the cooled mixture after heat energy exchange occurs in the cooling coil (241)

[0234] Air can be supplied to the lower part of the data center.

[0235] (Example 5-1) In Example 2-2, the refrigerant is carbon dioxide.

[0236] The temperature of the refrigerant moving through the first refrigerant moving pipe (310) is 5 degrees Celsius or higher.

[0237] Do it.

[0238] The refrigerant moved through the first refrigerant transfer pipe (310) is mixed with air in the air conditioner.

[0239] Heat exchange takes place. Here, if the temperature of the refrigerant is lower than 0 degrees Celsius, it is contained in the air.

[0240] The water vapor present can cause condensation. This can cause condensation on the surface of the pipe through which the refrigerant flows.

[0241] A layer of ice may form, reducing the thermal conductivity.

[0242] In this way, the temperature of the refrigerant flowing through the first refrigerant transfer pipe (310) is too low.

[0243] In the data center, condensation occurs during the heat exchange between the refrigerant and the mixed air.

[0244] , it may be necessary to prevent this. Therefore, the refrigerant flowing through the first refrigerant transfer pipe (310)

[0245] The temperature of the daisy can be set above 5 degrees Celsius. However, if it is too high, it may not be sufficient as intended by the designer.

[0246] Since no heat exchange can be achieved, it is preferable to set it to 7 degrees Celsius.

[0247] (Example 6-1) In Example 3-2, in the second refrigerant transfer pipe (320)

[0248] A 2-2 refrigerant transfer pipe that is divided and introduces a portion of the refrigerant into the absorption chiller (400).

[0249] (322);, the refrigerant cooled in the absorption chiller (400) is transferred to the first refrigerant transfer pipe

[0250] (310) and a first-second refrigerant transfer pipe (312) communicating with each other.

[0251] (Example 6-2) In Example 6-1, the absorption refrigerator (400) is low

[0252] A housing (410) having a pressure space (411); a nozzle for spraying moisture into the low pressure space (411);

[0253] Sano nozzle (420);, as the moisture sprayed in the low pressure space (411) evaporates, the moisture

[0254] A cooling tube (430) through which the refrigerant flows so that heat exchange can occur; and the low-pressure space

[0255] (411) contains an absorbent material (440) that absorbs moisture.

[0256] Referring to Figure 6, in an exemplary embodiment of the present invention, absorption refrigeration

[0257] It may further include a base (400) and a first-second refrigerant transfer pipe and a second-second refrigerant transfer pipe (322).

[0258] The 2nd refrigerant transfer pipe (322) is divided from the 2nd refrigerant transfer pipe (320) and

[0259] It may be a flow passage that introduces some of it into an absorption chiller (400).

[0260] The 1-2 refrigerant transfer pipe carries the refrigerant whose temperature has been lowered in the absorption chiller (400).

[0261] It may be a flow passage that joins the first refrigerant transfer pipe (310).

[0262] If the refrigerant does not sufficiently exchange heat in the heat exchange unit (100),

[0263] It is possible to cool the refrigerant through an absorption chiller (400).

[0264] Referring to Figure 4, the absorption chiller (400) includes a housing (410), a spray nozzle

[0265] (420), cooling tube (430), and absorbent material (440) may be included as components. The housing (410)

[0266] A low pressure space is provided, and the low pressure space contains an absorbent material (440).

[0267] Also, when moisture is sprayed into the low pressure space (411) by the spray nozzle (420), the moisture

[0268] It can be easily evaporated at low pressure. As moisture evaporates, it must absorb heat, and that heat

[0269] Absorption is obtained from the refrigerant. The refrigerant takes away heat in the process of flowing through the cooling tube (430).

[0270] It can be long.

[0271] The absorbent material (440) absorbs the evaporated moisture and fills the space within the housing (410).

[0272] It can play a role in maintaining low pressure continuously. Moisture absorption of absorbent material (440)

[0273] The ability needs to be periodically regenerated. The absorbent material (440) can be composed of various

[0274] However, it may preferably be composed of a lithium bromide (LiBr) solution. As above.
