Specifically, the scaled-down model of the rear door cooling device is a technology that implements an experimental device with a significantly reduced size while operating on the same principles as the rear door cooling device, and utilizes this to develop various optimal operating software algorithms for energy savings.
[0028] FIG. 1 is a drawing showing the configuration of a scaled-down model experimental system of a rear door cooling device according to one embodiment of the present invention.

[0030] The refrigerator case (100) is a configuration that performs a containment role within a data center, and can be implemented by disassembling an actual refrigerator and using only the external case excluding the internal parts.
[0031] The stainless steel pedestal (200) is implemented in the form of a small rack to simulate / perform the role of a data center rack. The water cooling cooler (300) is implemented as a PC water cooling cooler that simulates / performs the role of a rear door cooling device.
[0032] The cooling water refrigerant heat exchanger (400) is configured to perform heat exchange between the cooling water of the water-cooled cooler (300) and the refrigerant of the cooling module (500), and the refrigerant-type cooling module (500) is configured to cool the refrigerant. The cooling water refrigerant heat exchanger (400) and the cooling module (500) can be implemented as internal components of an actual refrigerator.
[0033] The optimal operation system (600) for air conditioning equipment is configured to control a water-cooled cooler (300), a cooling water refrigerant heat exchanger (400), and a cooling module (500) using a refrigerant method while monitoring the temperature of a stainless steel support (200) and a cooling water refrigerant heat exchanger (400) so as to save data center energy.
[0034] Fig. 2 is a drawing showing a detailed configuration of a stainless steel support (200) illustrated in Fig. 1. The rack-shaped stainless steel support (200) that functions as a rack is configured to include, as illustrated, a plurality of thermometers (210, 211, ..., 21n) and a plurality of PTC fan heaters (220, 221, ..., 22n).
[0035] PTC fan heaters (220, 221, ..., 22n) are configured to simulate the heat generation of IT equipment such as servers. The heat emitted from the PTC fan heaters (220, 221, ..., 22n) simulates the heat emitted from the rear door rack.
[0036] Thermometers (210, 211, ..., 21n) measure the temperature of air heated by heat emitted from PTC fan heaters (220, 221, ..., 22n) to measure the temperature of each section of the stainless steel stand (200).
[0037] Fig. 3 is a drawing showing a detailed configuration of a water cooling cooler (300) illustrated in Fig. 1. As illustrated, the water cooling cooler (300) is configured to include a plurality of EC fans (310, 311, ..., 31n).
[0038] EC fans (310, 311, ..., 31n) exhaust air heated by heat emitted from PTC fan heaters (220, 221, ..., 22n) of a stainless steel base (200).
[0039] Fig. 4 is a drawing showing a detailed configuration of a cooling water refrigerant heat exchange device (400) illustrated in Fig. 1. As illustrated, the cooling water refrigerant heat exchange device (400) is configured to include a refrigerant evaporator (410), a cooling water tank (420), a cooling water pump (430), and a thermometer (440).
[0040] The refrigerant evaporator (410) exchanges heat with the liquid refrigerant from the refrigerant-type cooling module (500) by contacting it with the cooling water tank (420), and the cooling water tank (420) exchanges heat with the cooling water from the water-cooling cooler (300) by contacting it with the refrigerant evaporator (410). As a result, the cooling water moved from the water-cooling cooler (300) to the cooling water tank (420) is cooled by the liquid refrigerant moved from the refrigerant-type cooling module (500) to the refrigerant evaporator (410).
[0041] The cooling water pump (430) is configured to circulate cooling water from the water-cooling cooler (300), and the thermometer (440) is configured to measure the temperature of the cooling water from the cooling water pump (430).
[0042] FIG. 5 is a drawing showing a detailed configuration of an air conditioning equipment optimal operation system (600) illustrated in FIG. 1. As illustrated, the air conditioning equipment optimal operation system (600) for energy saving is configured to include a temperature collection device (610), a power usage collection device (620), an energy saving optimal operation management device (630), a PTC fan heater remote variable control device (640), an EC fan remote variable control device (650), a cooling water pump remote variable control device (660), and a cooling module remote variable control device (670).
[0043] The temperature collection device (610) is configured to collect temperature from the thermometers (210, 211, ..., 21n) of the stainless steel stand (200) and the thermometer (440) of the cooling water refrigerant heat exchange device (400).
[0044] The power usage collection device (620) is configured to collect power usage data from a water-cooled cooler (300), a cooling water refrigerant heat exchanger (400), and a refrigerant-type cooling module (500).
[0045] The energy-saving optimal operation management equipment (630) calculates appropriate control values of the control equipment (650, 660, 670) described later according to the energy-saving optimal operation method based on the temperature collected by the temperature collection equipment (610), and transmits control commands to the control equipment (650, 660, 670) according to the calculated control values.
[0046] The PTC fan heater remote variable control device (640) controls the load of the PTC fan heaters (220, 221, ..., 22n) of the stainless steel stand (200) to change arbitrarily as the load of the IT equipment changes, or to change the load periodically according to the usage pattern.
[0047] The EC fan remote variable control equipment (650) receives control values for the EC fans (310, 311, ..., 31n) of the water-cooling cooler (300) from the energy-saving optimal operation management equipment (630), and remotely controls the rotation speed of the EC fans (310, 311, ..., 31n).
[0048] The cooling water pump remote variable control equipment (660) receives a control value for the cooling water pump (430) of the cooling water refrigerant heat exchange device (400) from the energy saving optimal operation management equipment (630) and controls the rotation speed of the cooling water pump (430).
[0049] The cooling module remote variable control equipment (670) receives control values for the refrigerant-type cooling module (500) from the energy-saving optimal operation management equipment (630) and remotely controls the refrigerant temperature of the refrigerant-type cooling module (500).
[0050] The energy-saving optimal operation method of the scaled-down model experimental system of the rear door cooling device by the optimal operation system of the air conditioning equipment (600) is illustrated in Fig. 6.
[0051] As shown, first, the energy saving optimal operation management equipment (630) checks the temperature of the thermometer (440) collected by the temperature collection equipment (610), i.e., the temperature of the outlet of the cooling water tank (420) (S710).
[0052] If the confirmed temperature is higher than the critical temperature, the energy-saving optimal operation management equipment (630) calculates control values for the EC fans (310, 311, ..., 31n), the cooling water pump (430), and the refrigerant-type cooling module (500) (S720). The control values are calculated using an artificial intelligence model that calculates the above control values from the temperature of the outlet of the cooling water tank (420).
[0053] And the energy saving optimal operation management equipment (630) controls the EC fans (310, 311, ..., 31n), cooling water pump (430), and refrigerant type cooling module (500) through variable control equipment (650, 660, 670) with the control values calculated in step S720 (S730).
[0054] The next energy saving optimal operation management equipment (630) checks the power usage collected through the power usage collection equipment (620) (S740).
[0055] If it is confirmed that power usage has decreased in step S740, the energy saving optimal operation management equipment (630) provides a reward to the artificial intelligence model that calculates control values to enable learning (S750).
[0056] Afterwards, steps S710 to S750 are repeated to optimize the artificial intelligence model that calculates control values for energy saving.
[0057] So far, a method for manufacturing and operating a scale model of a rear door cooling device has been described in detail with a preferred embodiment.
[0058] In the above example, an experimental environment was constructed with a number of rear-door cooling devices at low cost and in a small space, and these were utilized to develop various types of optimal operation software algorithms, thereby reducing data center air conditioning energy.
[0059] This allows for experiments on various air conditioning methods to be conducted at low cost and in a small space through a number of scale models of rear-door cooling devices, and allows for the remote control of IT equipment load and the fan speed of each scale model of rear-door cooling devices by software, enabling the development of various energy optimization algorithms using artificial intelligence.
