In addition, a power strip capable of detecting power consumption may be configured in a rack, and servers mounted on the rack may be respectively connected to the corresponding power strip.

The air conditioner supplies cold air to the first chamber unit 1, and the cold air supplied to the first chamber unit 1 passes through the perforated plate and is supplied to the rack to absorb the heat of the rack. The heat generated by absorbing the heat is introduced into the air conditioner through the second chamber part 2 and undergoes a process of lowering the temperature of the computer room.

However, since the conventional system for controlling the temperature of the computer room operates to supply cold air from the air conditioner by sensing the temperature for the entire computer room depending on the detection information of a simple temperature sensor, it is difficult to efficiently operate the air conditioner, so power consumption due to the air conditioner and cost is a significant problem.

In addition, the existing system does not have a structure in which cold air is concentrated and supplied to the rack, so the amount of cold air required to lower the temperature of the rack is considerable, and cold air is supplied to the rack only when the chamber is filled with cold air, so the computer equipment inside the rack is driven There is a problem in that even when the amount of heat is small after stopping for a while, there is a problem in that more cold air must be generated, and there is a problem that the energy efficiency for cooling is extremely low.

In addition, since the existing system has a structure in which the air conditioner completely processes the heat generated while cooling the inside of the computer room, there is a problem in that a considerable cost occurs due to the continuous operation of the air conditioner.

Hereinafter, the components constituting the computer room temperature control system for efficiently cooling the heat generated in the rack in which the computer equipment is mounted will be described in detail.

First, the air conditioning unit 110 may be disposed inside the computer room and configured to inject cold air into the interior (internal space) of the first chamber unit 12 . In this case, the air conditioning unit 110 may be composed of various devices for generating cold air, such as an air conditioner, a constant temperature and humidity device, and the like.

In addition, the one or more variable structures 120 may be configured to be adjustable in volume by being configured in the first chamber part 12 .

In this case, the variable structure 120 may be configured inside the first chamber part 12 in a state of being connected to the lower portions of the plurality of frames, and may be configured to have a variable volume when air is injected.

As an example of such a deformable structure 120 , the deformable structure 120 may be configured as a tube.

In addition, a portion of the floor surface may be formed of a perforated plate 130 having a plurality of holes formed therein in place of the floor tile, and the perforated plate 130 may be disposed to be supported by the frame.

In addition, a plurality of perforated plates 130 may be disposed to constitute a part of the bottom surface, and the plurality of perforated plates 130 may be disposed adjacent to the rack 11 . In this case, a part of the plurality of perforated plates 130 may be disposed to be spaced apart from each other with a floor tile interposed therebetween.

At this time, when the detailed configuration of the perforated plate 130 is described with reference to FIG. 3 , the perforated plate 130 has a plurality of holes formed therein when disposed to form the bottom surface through the holes. 1 The cold air stored in the chamber unit 12 can be introduced into the computer room.

Here, if cold air is simply introduced into the hole of the perforated plate 130, the cold air is not properly supplied to the rack 11, so the perforated plate 130 according to an embodiment of the present invention provides the cold air at the lower part based on the bottom surface. A plurality of guide structures 131 diagonally arranged to guide the rack 11 in a direction in which it is positioned may be formed.

Through such a structure of the perforated plate 130, the perforated plate 130 can concentrate the cold air in the direction in which the rack 11 is positioned through the guide structure 131. can be cooled.

At this time, the guide structure 131 may be configured to be rotatable under the perforated plate 130 , and through this, the guide structure 131 is rotated to be diagonally disposed in the opposite direction to the direction in which the rack 11 is located. It is possible to control the cold air to flow in the direction in which the rack is located through the guide structure 131 .

On the other hand, the chimney unit 150 has the second chamber so that the lower surface of the chimney unit 150 is disposed to be in contact with the ceiling surface and each of the plurality of outlet ports 154 configured on the ceiling surface penetrates the outer surface (or outer circumference surface) of the chimney unit 150 . It is configured in the unit 13, and the heat generated in the internal space of the computer room in which the rack 11 of the computer room is arranged is sucked inside through the outlet 154 and delivered to the air conditioning unit 110. can

In this case, the chimney unit 150 may be configured integrally with the second chamber unit 13 or may be configured to be disposed inside the second chamber unit 13 .

In addition, the chimney unit 150 may be configured to include a plurality of duct units.

At this time, the first duct part 151 among the plurality of duct parts may be formed (configured) at one end of the chimney part 150, and selectively suck the outside air to be introduced into the chimney part 150 inside. It may be configured to cool the heat introduced into the chimney unit 150 into the outside air by inducing it.

In addition, the second duct part 152 among the plurality of duct parts may be configured to extend (extended and formed) to a part of the first duct part 151 to transfer the heat to the air conditioning unit 110 . .

Accordingly, the chimney unit 150 selectively transfers the heat introduced into the chimney unit 150 through the outlet 154 through the first duct unit 151 and the second duct unit 152 . It may be transmitted to the air conditioning unit 110 .

At this time, the chimney unit 150 selectively allows the outside air to be sucked (introduced) into the chimney unit 150, or selectively transmits the heat from the chimney unit 150 to the air conditioning unit 110. It may be configured to include an opening/closing part to make it possible.

As an example of the opening/closing unit, the opening/closing unit may include a plurality of valves, and in more detail, is configured on one side of the first duct unit 151 to open and close the first duct unit ( A first valve (153a) for selectively transmitting outside air to the inside of 151), and configured on the other side of the first duct unit (151) to selectively open and close the heat inside the chimney unit (150) of the first The first duct 151 and the second duct are transferred to the inside of the duct part 151 or the outside air introduced into the first duct part 151 is selectively transferred to the inside of the chimney part 150 and opened and closed according to the opening and closing. The second valve 153b for selectively transferring heat to the air conditioning unit 110 through the unit 152 and the other end of the chimney unit 150 are configured at the other end of the chimney unit 150 to open and close the heat inside the chimney unit 150 . may be configured to include a third valve 153c for selectively flowing (discharging) to the outside.

In addition, the computer room temperature control system may further include an outdoor air sensor unit for measuring (sensing) the outside air temperature, generating outside air temperature information about the outside air temperature, and transmitting the generated outside air temperature information to the management unit 200 .

Accordingly, the management unit 200 sets at least one of the sensing information on the heat received from the temperature sensor 160 configured inside the chimney unit 150 and the outdoor temperature information received from the outdoor air sensor unit in a preset plurality. In comparison with the opening/closing setting information in which the opening/closing setting state of each of the first to third valves 153a, 153b, 153c is set for each environmental condition of Identifies a specific environmental condition satisfied by at least one of a temperature and an outside temperature according to the outside temperature information, and sets the opening/closing for each of the first to third valves 153a, 153b, and 153c in response to the specific environmental condition The opening/closing state of the first to third valves 153a, 153b, and 153c may be controlled by the opening/closing setting state set in the information.

In this case, the opening/closing setting information may be previously stored in the management unit 200 .

As an embodiment of the opening/closing control for the first to third valves 153a, 153b, and 153c of the management unit 200 described above, the first environment in which the temperature of the outside air is preset in the opening/closing setting information because the external weather is sufficiently cold If less than the first reference value according to the condition is satisfied, the management unit 200 corresponds to the first environmental condition and sets the opening/closing setting state for the first to third valves 153a, 153b, 153c preset in the opening/closing setting information. Accordingly, the first valve 153a, the second valve 153b, and the third valve 153c are controlled in an open state so that outside air flows into the chimney unit 150 into the outside air chimney unit 150 inside. can cool the heat of

At this time, the first valve (153a) and the second valve (153b) are opened to cool the heat inside the chimney unit 150 through cold air, which is the outside air introduced into the chimney unit 150, as well as the second valve. 3 By opening the valve 153c, the heat introduced into the chimney unit 150 may be discharged (discharged) to the outside.

Through this, it is possible to increase energy efficiency by reducing the load required for cooling the hot air of the air conditioning unit 110 .

In addition, when the hot air temperature according to the sensing information received from the temperature sensor inside the chimney unit 150 is equal to or greater than a second reference value according to a second environmental condition preset in the opening/closing setting information, the outdoor air temperature information received from the outdoor air sensor unit When the outside temperature according to the temperature is less than the third reference value according to the second environmental condition, the management unit 200 corresponds to the second environmental condition and sets the first to third valves 153a, 153b, 153c in advance in the opening/closing setting information. ), the first valve 153a and the third valve 153c may be controlled in an open state, and the second valve 153b may be controlled in a closed state according to the opening/closing setting state.

Through the above-described configuration, the heat inside the chimney unit 150 can be cooled only with the outside, and the heat introduced into the chimney unit 150 through the opening of the third valve 153c is discharged to the outside for cooling. Efficiency can be further increased.

In the above-described configuration, a plurality of different free cooling conditions for cooling only the outside air instead of the first and second environmental conditions may be preset in the management unit 200 , and a plurality of different free cooling conditions may be set in advance. A temperature range for the outside air temperature, an open/close state of the first to third valves 153a, 153b, and 153c, and an open rate of the second valve 153b may be set for each.

At this time, the temperature range between the different outdoor air cooling conditions and the opening rate of the second valve 153b may be set in advance in the management unit 200 to be different from each other, and the setting for the outdoor air cooling condition is the opening/closing setting information may be included in

Accordingly, the management unit 200 corresponds to a temperature range to which the outside air temperature received from the outside air sensor unit belongs among a plurality of temperature ranges for each outside air cooling condition according to the opening rate of the second valve 153b set in advance. The valve 153b may be controlled to be completely closed or open or partially open.

In this case, the management unit 200 may control the first valve 153a and the third valve 153c in an open state under all outdoor cooling conditions.

In this way, the management unit 200 adjusts the opening rate of the second valve 153b according to the outside air temperature, so that the appropriate cold air in which the cold outside air and the heat of the chimney unit 150 are mixed is appropriate through the air conditioning unit 110 . It is possible to increase the energy efficiency of the computer room by allowing the temperature cold air (eg, about 20℃) to be introduced into the computer room.

In addition, the management unit 200 sets the outside air temperature according to the outside air temperature information received from the outside air sensor unit and the hot air temperature according to the sensing information received from the temperature sensor inside the chimney unit 150 to a preset third environmental condition. According to each other, the outdoor air temperature is lower than the hot air temperature inside the chimney unit 150, the difference between the outdoor air temperature and the hot air temperature is less than or equal to a preset fourth reference value, and the hot air temperature is preset according to the third environmental condition. When the fifth reference value or more, it is possible to cool the inside of the chimney unit 150 by using the outside air, but since the hot air temperature inside the chimney unit 150 is above a certain level, it may be determined that cooling is insufficient only with the outside air.

Accordingly, the management unit 200 sets the third valve 153c for discharging the heat inside the chimney unit 150 when the hot air temperature and the outside air temperature satisfy the third environmental condition. The third valve 153c may be opened for the purpose of introducing outside air into the furnace, and the second valve 153b may be opened while the first valve 153a is closed.

At this time, when the outside air temperature is lower than the hot air temperature, but the difference is not large, the third valve 153c is used instead of the first valve 153a for the purpose of introducing the outside air, and the third valve 153c is opened through the chimney part. Outside air can be directly supplied to the inside of the chimney unit 150 , and thus the amount of air inside the chimney unit 150 in contact with the outside air can be increased to efficiently cool the heat inside the chimney unit 150 .

Through this, the outside air introduced through the opening of the third valve 153c can sufficiently collide with the heat inside the chimney unit 150 to cool the heat inside the chimney unit 150 and the second valve 153c. By closing the first valve 153a and opening the second valve 153b, the heat inside the chimney unit 150 is transferred to the air conditioning unit 110 in a state cooled to some extent by the outside air, It is possible to efficiently cool the hot air inside the chimney unit 150 through the mixed use of the air conditioning unit 110 and the outside air while reducing the load required for cooling the hot air in the air conditioning unit 110 .

As another example, when the outside air temperature according to the outside air temperature information received from the outside air sensor unit is higher than or equal to a sixth reference value according to a fourth environmental condition preset in the opening/closing setting information, and thus the outside air temperature is high, the management unit 200 controls the outside air determines that it cannot be used for cooling the hot air inside the chimney unit 150, and opens and closes the first to third valves 153a, 153b, 153c preset in the opening/closing setting information in response to the fourth environmental condition According to the setting state, the first valve 153a and the third valve 153c are controlled to close, and the second valve 153b is controlled to open to block the outside air and the heat inside the chimney unit 150 is removed. The heat inside the chimney unit 150 may be cooled by being transferred to the air conditioning unit 110 and only by the cooling operation of the air conditioning unit 110 .

Of course, as for the environmental conditions set in the above-described opening/closing setting information, various conditions and opening/closing states of the first to third valves for each condition may be set in addition to the above-described examples.

As described above, the present invention can increase energy efficiency by reducing the cooling load of the air conditioning unit by selectively using the outdoor air for the heat generated inside the computer room in consideration of the temperature outside the computer room and the heat generated inside the computer room.

In addition, in the above configuration, the opening and closing unit is configured to communicate with the management unit 200 , and may be driven or opened/closed according to the control of the management unit 200 . For example, each of the valves 153a, 153b, and 153c included in the opening/closing unit may be configured as a module capable of communicating with the management unit and may be opened and closed as described above under the control of the management unit 200 .

In addition, in the above configuration, at least one of the plurality of valves constituting the opening/closing unit may be configured as a fan, and the management unit 200 selectively controls whether the fan is driven through the fan. Outside air may be introduced into the chimney unit 150 , or heat inside the chimney unit 150 may be transferred to the air conditioning unit 110 .

Alternatively, at least one of the plurality of valves constituting the opening/closing unit may selectively introduce outside air into the chimney unit 150 or selectively transmit the heat inside the chimney unit 150 to the air conditioning unit 110 . It can be constituted by a rotating shaft or other means.

In this case, it is preferable that the means constituting the opening/closing part is a means by which the opening/closing rate is adjusted.
