Description

PRECISION AIR CONDITIONING MACHINES FOR MODULAR DATA CENTER SYSTEM, AND METHOD OF OPERATION FIELD OF THE INVENTION

[0001] This innovation belongs to the field of Engineering, specifically in its technological aspect of modular infrastructure, more specifically in structures developed for precision air conditioning machines used in data processing centers, but the invention is not limited to this single field, since the product can be applied in the most diverse technological areas of Engineering. BACKGROUND OF THE INVENTION

[0002] The demand for data center facilities has been steadily increasing with the rise in global connectivity. This growth directly impacts the capacity for data storage, processing, and control, which can be used in a wide variety of industries, businesses, offices, shopping malls, commercial establishments, and even leisure environments. All the technology applied in these diverse solutions relies on a data center for its operation.

[0003] The demand for data centers available for the completion of construction projects in periods of less than one year is a need that remains unsolved in the current state of the art, with traditional masonry constructions typically taking around three years, depending on the data center's capacity. However, the urgency for data centers to become operational requires that this development and installation time be reduced, potentially reaching a timeframe of less than six months, starting with contracting, then project development, manufacturing, transportation, installation, testing, and activation.

[0004] Another challenge in the state of the art is the development of components with specific requirements for use in self-transportable data centers, preferably for expanding the processing or storage capacity of the data center. More specifically, this relates to the data center's operating parameters, which are controlled by precision air conditioning units.

[0005] Another problem with the current state of the art is the impossibility of quickly and easily expanding an already operating data center to increase its cooling capacity by accurately sizing the cooling load, thus avoiding problems with the use of off-the-shelf equipment that is either undersized or oversized, both of which have their technical problems. While undersizing will damage the optimal functioning of the data center, potentially even burning out equipment due to lack of adequate cooling, oversizing will result in excessive energy consumption, increasing the data center's operating costs.

[0006] Aiming to obtain a solution that resolves all the technical problems listed above, with all their adversities, this document describes a precision air conditioning machine for a modular data center system, capable of meeting all the operational requirements of a modular and self-transportable data center.

[0007] Several solutions have been developed seeking optimization and improvements for data centers, more specifically in solutions for air conditioning units or cooling rooms, given the extensive use of this equipment. And, for the evolution of cooling rooms, or other data center rooms, we need precision air conditioning units with excellent energy efficiency, specifically designed to meet this type of use.

[0008] In 2023, patent CN116669403 proposed a modular data center with a cooling module, composed of several cold air channels, and a specific device developed to improve the cooling operation of the cabinets. This device consists of rings and springs connected to the air intake channel. The solution developed in this document presents a specific structure for the cooling operation of the data center. This structure is designated as a precision air conditioning machine. Unlike the solution proposed in patent CN116669403, the solution of this innovation includes a structure that has the characteristic of progressively increasing cooling capacity, in order to guarantee the best energy efficiency and maintain the ideal operating conditions for the data equipment.

[0009] In 2020, patent US20200245510 described a solution using an air conditioning system to cool buildings, such as data centers. Although the described solution aimed for energy savings, given the extremely high energy consumption for cooling the environment, the developed solution differs completely from the solution proposed in this document. This is because the fan placement in patent US20200245510 forms a vertical wall, while the present solution uses horizontal structures, which ensure greater energy efficiency.And the main point is that patent US20200245510 lacks the key differentiating factor of this innovative solution, which is the precise control of the generated cooling load and the possibility of progressively increasing the cooling capacity in order to achieve the greatest possible energy savings, activating only the circuits that are actually necessary to meet the demand at any given moment.

[0010] In 2009, patent US20110100045, whose patent family includes patent BR112012010390, proposed an innovative cooling system for data centers. However, the method of performing the cooling operation described in patent US20110100045 is quite different, as it uses water for cooling, while the solution described in this document uses air. It is important to highlight that the text of patent US20110100045 also describes the crucial aspect of energy consumption, reinforcing the importance of the developed solution.

[0011] In summary, none of the documents available in the state of the art proposed the development of a precision air conditioning machine for a modular data center system, capable of being developed and available for the data center to be operational in less than six months, capable of providing all the requirements and parameters specified for the cooling operation of the data center, and still guaranteeing the variability of the operating parameters according to the instantaneous needs of the modular data center system operation, through robust control and programming that economically and efficiently meets all conditions, from an initial load of 0 Tons of Refrigeration (TR) to loads exceeding 30 TRs.The problem of controlling equipment wear is also being solved through intelligent control, which monitors the use of all components of the solution in order to maintain the same usage time for all components, thus guaranteeing the extension of the standard lifespan for all components in the modular system installation, which uses the precision air conditioning machine. OBJECTIVES OF THE INVENTION

[0012] The present innovation aims to develop a precision air conditioning machine, preferably used in a modular data center system, capable of enabling the safe operation of a data center in both outdoor and indoor environments, whether closed or partially closed.

[0013] It is also the objective of the precision air conditioning machine to guarantee the temperature parameters of the internal area of ​​the modular data center system, which are requirements for the safe and reliable operation of the data center, even if there is variation in the cooling load demand throughout the work period.

[0014] Furthermore, the innovation also aims to optimize the size of the precision air conditioning unit to ensure all the necessary conditions for its operation within a data center, and, if necessary, the precision air conditioning unit can be removed through the data center's access door without needing to be disassembled for such removal.

[0015] The structure of the precision air conditioning machine also needs to be rigid and robust enough to withstand all the mechanical stresses during transport from the data center; in other words, it must be portable.

[0016] Finally, the modular data center system has the versatility of having its cooling load capacity scalable, through the use of only one circuit, or the use of both circuits simultaneously.

[0017] Furthermore, regarding the operation of the precision air conditioning machine, the objective of this solution is to protect its operating method within a modular data center system. BRIEF DESCRIPTION OF THE FIGURES

[0046] The precision air conditioning machine, developed in the present invention, aims to develop modules divided into sub-parts, in order to allow scalable operation, optimized according to the instantaneous cooling load demand, mainly to meet the requirements of a modular data center system.

[0047] All sub-parts are structurally self-supporting even when pre-equipped, and can be coupled and uncoupled according to the needs of transport, testing and commissioning.

[0048] The modular solution also allows for a system with variable capacities exceeding 30 tons of refrigeration. For example, for a total capacity of 30 TRs, the precision air conditioning unit has its evaporator and condenser divided into two parts, each part varying from 0 to 15 TRs, thus the total capacity of the precision air conditioning unit varies from 0 to 30 TRs.This division of both the evaporator and the condenser into two circuits that can operate individually or together allows for a reduction in energy consumption of up to 96% under extreme conditions. For example, if a precision air conditioning unit capable of producing a cooling load of up to 30 TRs requires a cooling load of only 1 TR at a given moment during operation, the control system automatically shuts off one of the condenser circuits, and the other circuit operates at its capacity, close to the minimum load, which in this example is 1 TR. By shutting down one of the condenser circuits and operating with the second circuit at its minimum capacity, significant energy savings are possible, in addition to ensuring the safe operation of the equipment, which is constantly monitored.

[0049] Other configurations can be scaled to accommodate a wide variety of modular data center system sizes. For example, for a modular system requiring up to 15 TRs, the precision air conditioning unit will be divided into two parts, each ranging from 0 to 7.5 TRs, thus the total capacity of the precision air conditioning unit will vary from 0 to 15 TRs. For another system requiring up to 7 TRs, the precision air conditioning unit will be divided into two parts, each ranging from 0 to 3.5 TRs, thus the total capacity of the precision air conditioning unit will vary from 0 to 7 TRs.

[0050] In order to show how the solution is developed, preferably for a modular data center system, Figure 1 is presented, which is a front perspective view of the modular data center system. In this view, it is possible to visualize the upper part of the two precision air conditioning units. Figure 1 also indicates the orthogonal axes X, Y, and Z. The X-axis indicates the longitudinal direction of the structures, a dimension also known as the length of the structures; the Z-axis indicates the transverse direction of the structures, a dimension also known as the width of the structures; and finally, the Y-axis indicates the direction parallel to the height of the structures.

[0051] The right side view, illustrated in Figure 2, shows a modular data center system, which uses two precision air conditioning units, only one of which is visible in this figure. Other alternative configurations can be used, since a modular data center system can have different configurations, including redundancies of the 2n type; or 2n+1; among others; depending on the capacity and type of data center in which the precision air conditioning unit will be used. That is, even if only one precision air conditioning unit is capable of meeting the cooling parameters of the modular data center system, due to the redundancy requirement, two precision air conditioning units are installed exclusively to meet this requirement.Figure 2 also identifies sections AA and BB, which were positioned to allow for a detailed visualization of the assembly of the precision air conditioning units in the modular data center system.

[0052] The enlarged front view, illustrated in Figure 3, shows a preferred configuration of the modular data center system. Figure 3 was projected through section AA, which is indicated in Figure 2, in order to allow a more detailed view of each of the precision air conditioning units.This figure shows the condenser units mounted on the upper exterior of the modular data center structure, while the evaporator units are protected and positioned internally within the modular data center structure. They are fixed to the base of the structure using supports designed to withstand all static and dynamic loads, both during the use of the precision air conditioning unit and during the transport of the modular data center system. This transport is necessary to move the data center to its operating location, which may even be relocated according to specific needs for end-customer service and the availability of conditions necessary for the optimal functioning of a data center.

[0053] The bottom view illustrated in Figure 4 shows a preferred configuration of the modular data center system. Figure 4 was projected using section BB, which is indicated in Figure 2, in order to allow a more detailed visualization of each of the precision air conditioning units. Furthermore, the bottom view of section BB shows the hot air inlets in the precision air conditioning units; these hot air inlets are the hatched regions, due to the section, identified in the precision air conditioning units by their respective numerical references.

[0054] The top view illustrated in Figure 5 shows a preferred configuration of the modular data center system. Also in Figure 5 is the partial cross-sectional area CC, in order to allow a more detailed view of one of the precision air conditioning units.

[0055] To illustrate how the solution is assembled within the modular data center system, Figure 6 is presented, showing an enlarged, right-side view projected through the partial section CC indicated in Figure 5. Some of the components used in the solution, from the precision air conditioning unit, have been identified with their respective numerical references. At the bottom of Figure 6 is the raised floor for cold air supply; this raised floor functions as a supply duct. Meanwhile, the entire internal area of ​​the modular data center system is used for the return of hot air; that is, the entire interior of the machine room functions as a return duct. Also at the bottom of Figure 6 is the area of ​​operation of the fans that pull in all the hot air, forcing the flow to pass through the components of the precision air conditioning unit, filling the supply duct and directing the cooled air into the data center.In the upper part of Figure 6, the condenser unit is mounted. In this side view, it is possible to see the difference in the height of the supports between the right and left sides of the image. This difference is calculated to accommodate the slope of the external roof structure on which the condenser unit is installed. In this way, the roof slope is canceled out by the difference in the heights of the supports, and the condenser unit is installed horizontally aligned.

[0056] The enlarged rear perspective view, illustrated in Figure 7, shows the assembly of two evaporators from precision air conditioning units. The piping connected to the respective condenser units is located above the evaporators.

[0057] The enlarged front view shown in Figure 8 illustrates the assembly of two evaporators from precision air conditioning units, positioned facing each other to optimize the space occupied during installation.

[0058] The enlarged rear perspective view, illustrated in Figure 9, shows the evaporator unit of the precision air conditioning machine. This figure allows for a detailed view of the right and left front doors of the evaporator unit, as well as one of the side panels and its respective side support column.

[0059] The enlarged right side view, illustrated in Figure 10, shows the evaporator of the precision air conditioning machine, with the DD section indicated. Figure 10 also shows the human-machine interface (HMI) used for parameterizing the operation of the precision air conditioning machine. The fans, preferably of the radial type, are located in the lower part of Figure 10.

[0060] The enlarged rear view shown in Figure 11 depicts the evaporator unit of the precision air conditioning machine, as designed using section DD.

[0063] The enlarged top view, illustrated in Figure 14, shows the evaporator of the precision air conditioning machine, with the FF section indicated.

[0064] The enlarged left side view shown in Figure 15 depicts the evaporator of the precision air conditioning machine, projected through section FF, which is indicated in Figure 14. This view identifies the components of the evaporator with their respective numerical references: the variable compressor; the flexible connection; the electrical panel; the temperature and humidity sensor; the coil; and the connection.

[0065] The enlarged left side view, illustrated in Figure 16, shows the evaporator of the precision air conditioning unit. This view shows the rear enclosures of the evaporator and how these enclosures are mounted on the support columns and side support columns.

[0066] The enlarged rear perspective view illustrated in Figure 17 shows the structure of an evaporator unit from a precision air conditioning machine, isolated from the assembly with the other components that make up the evaporator. In this view, the evaporator components are hidden to allow visualization only of the structural part of the evaporator. Although the closures and doors are part of the evaporator structure, these components have also been hidden to allow a better view of the internal structure of the evaporator.

[0067] The enlarged rear perspective view, illustrated in Figure 18, shows the exploded view of the evaporator unit structure of the precision air conditioning machine, isolated from the assembly with the other components that make up the evaporator.

[0072] The enlarged front view, illustrated in Figure 23, shows the condenser unit of the precision air conditioning machine, designed using section GG, which is indicated in Figure 22. Figure 23 shows the inclination of the condenser unit's side walls; this inclination optimizes the height required to achieve the same efficiency. The angled opening facilitates the airflow drawn in by the fan, requiring little space for operation. Therefore, the condenser unit can be installed in a smaller space, making it ideal for installation in modular data center systems that are transportable.

This view identifies the condenser unit components with their respective numerical references: coil; fan; electrical junction box; top cover; latch; mounting bracket; divider; base; side cover; support 1; support 2; and control.

[0077] The precision air conditioning machine (100) developed in this document was preferably developed for use in a modular data center system (200), whose rooms preferably have a door with an access opening width varying between 0.6 m and 1.6 m, and more commonly between 0.8 m and 1.2 m, thus it is important that the depth of the evaporator (1), which is mounted inside the room, is less than 80 cm or even less than 60 cm, depending on the specification of the door of the modular data center system (200).

[0078] Each precision air conditioning machine (100), developed in the present solution, is assembled with an evaporator (1) and a condenser (2). Each evaporator (1) is assembled with a fan (1.1), variable compressor (1.2), flexible connection (1.3), electrical panel (1.4), temperature and humidity sensor (1.5), coil (1.6), connection (1.7), humidifier (1.8), resistor (1.9), flow regulator (1.10), interface (1.11), right front door (1.12), left front door (1.13), side closure (1.14), rear closure (1.15), side support column (1.16), support column (1.17), filter (1.18), drain tray (1.19), housing (1.20), lower base (1.21), upper base (1.22), divider (1.23) and locking profile (1.24). Each condenser (2) is assembled with coil (2.1), fan (2.2), electrical junction box (2.3), top closure (2.4), latch (2.5), fixing bracket (2.6), divider (2.7), base (2.8), side closure (2.9); support 1 (2.10); support 2 (2.11) and control (2.12).

[0079] The evaporator (1) has the function of cooling the hot air in the environment. And to perform this function, the evaporator (1) has specific components, each of which has its function and importance in achieving the final objective of the evaporator (1).

[0080] The fan (1.1) is preferably of the radial type and has the function of moving the airflow through the data center's cooling circuit, and this flow, as in the condenser (2), is also regulated by the PLC.

[0081] The variable compressor (1.2) has the function of compressing the refrigerant gas in the refrigeration circuit of the precision air conditioning machine (100), and, just like the operation of the fan (1.1), the operation of the variable compressor (1.2) is also regulated by the PLC.

[0082] The flexible connection (1.3) has the function of absorbing vibrations and stresses during the operation of the system and also during the transport of the precision air conditioning machine (100), preventing possible damage to the connection (1.7).

[0083] The electrical panel (1.4) has the function of housing the electronic components that make up the electrical system of the precision air conditioning machine (100).

[0084] The temperature and humidity sensor (1.5) has the function of constantly measuring temperature, pressure and humidity, providing data to the programming software of the precision air conditioning machine (100).

[0085] The coil (1.6) has the function of cooling the air, exchanging heat through the contact of the surface with the refrigerant fluid inside it.

[0086] Connection (1.7) has the function of transporting the refrigerant fluid through the system.

[0087] The humidifier (1.8) has the function of increasing the humidity, when necessary, in the environment of the modular data center system (200).

[0088] The resistor (1.9) has the function of reducing humidity, when necessary, in the modular data center system (200).

[0089] The flow regulator (1.10) is the shut-off and sealing device that regulates the airflow, and interrupts it when necessary.

[0090] The interface (1.11) is the human-machine interface device used to turn on, turn off and regulate precision air-conditioning machine (100).

[0091] The right (1.12) and left (1.13) front doors are the access points for maintenance of the evaporator (1), and also serve as a seal for the system.

[0092] The side (1.14) and rear (1.15) closures serve to seal the system.

[0093] The side support columns (1.16) and support columns (1.17) serve as structural points to which the doors and closures are attached.

[0094] The filter (1.18) through its ability to continuously filter the air, ensures the conditions necessary for the operating environment of the modular data center system (200).

[0095] The drain pan (1.19) collects all water condensation from the refrigeration system and removes it through a drain.

[0096] The housing (1.20) provides isolation of the connection (1.7) and the variable compressor (1.2) from the rest of the evaporator (1).

[0097] The lower base (1.21) is the support base for the precision air conditioning machine (100).

[0098] The upper base (1.22) is the upper support structure of the precision air conditioning machine (100).

[0099] The splitter (1.23) is the separation structure of the evaporator circuits (1).

[0100] The locking profile (1.24) is the mechanical lock for the structural components of the evaporator (1).

[0101] To mount the evaporator (1) in the modular data center system room (200), bases are used that are dimensioned to withstand all the torsional and bending forces and moments to which the evaporator (1) is exposed during the lifting operation for transport, during the transport operation itself, or even during the ground handling operation of the modular data center system (200), in which the evaporator (1) is mounted. The dimensioning of such bases is extremely important, since to meet the requirement of the modular data center system (200) being available for operation in a short period, all modules need to be transported with all their respective components assembled.

[0102] The condenser (2) has the function of dissipating the heat absorbed by the refrigerant during the cooling process. In the cooling process, the refrigerant gas exchanges heat with the environment when it passes through the coil (2.1), which is exposed and subjected to an airflow through the action of the fans (2.2). The coil (2.1) has the technical function of exchanging heat through the contact of its surface with the heated refrigerant fluid inside. The fans (2.2) have the technical function of promoting airflow through the coil (2.1) in order to remove heat from the coil (2.1). The fans (2.2) are preferably of the axial type and are driven by the control (2.12), which is preferably a programmable logic controller, also known as a "PLC". The control (2.12) constantly regulates the operating speed of the fans (2.2) according to the cooling demand of the modular data center system (200).The use of two fans (2.2) allows for better optimization and refinement of the airflow speed regulation required to achieve the ideal parameters for the momentary cooling load of the modular data center system (200). The electrical junction box (2.3) serves to house the electrical connectors for the fan (2.2).

[0103] The entire structure of the condenser (2), including its top closure (2.4), the latch (2.5), the mounting bracket (2.6), the divider (2.7), the base (2.8), the side closure (2.9), support 1 (2.10), and support 2 (2.11), serves to assemble and structure the condenser (2). Specifically, the top closure (2.4), which closes the top of the condenser (2), is the base for installing the fans (2.2). The latch (2.5) provides mechanical locking of the condenser (2) structure. The mounting bracket (2.6) is the inclined side structure where the coil (2.1) is fixed. The divider (2.7) is the structure that separates the circuits of the condenser (2). The base (2.8) is the lower structure that supports all other structures of the condenser (2). The side closure (2.9) is the structure that closes the ends of the condenser (2).

[0104] The condenser (2) has a difference in support heights between the right and left sides; this difference is calculated to accommodate the slope of the external roof structure on which the condenser (2) is installed. Thus, on the sloped side are positioned supports 2 (2.11), which are higher, while on the opposite side are positioned supports 1 (2.10), which are lower. In this way, the roof slope is canceled out by the difference in support heights, and the condenser (2) is installed horizontally aligned. Both supports 2 (2.11) and support 1 (2.10) have an adjustment system in order to refine the correct height of the condenser (2) and ensure its horizontal installation position.

[0105] The precision air conditioning machine (100) can alternatively be formed by only one fan (2.2) on each side of the condenser (2), since the number of fans is not a limiting factor in the scope of the solution. The sizing of the fan (2.2) is carried out according to the airflow required for the operation of the precision air conditioning machine (100), and the area available for the installation of the condenser (2) is also taken into account in sizing the size and number of fans.

[0106] The condenser (2) is preferably manufactured from stainless steel raw material in order to protect its structure against the weather conditions to which the condenser (2) is exposed.

[0107] Alternatively, the condenser (2) can have its structure manufactured with different raw materials that exhibit resistance to exposure to the elements, such as: polymers; steels with surface treatments, aluminum, among other raw materials that meet this requirement.

[0108] The operating method developed for the operation of the precision air conditioning machine (100) receives information from the temperature and humidity sensor (1.5) and compares the actual temperature and humidity with the programmed ideal temperature and humidity through the control (2.12). If the actual temperature is equal to the ideal, no action is required. If the actual temperature is higher than the ideal temperature, the control system (2.12) increases the airflow generated by the fans (2.2) in order to decrease the temperature of the modular data center system (200) and ensure the efficiency and safety of the equipment. If the actual temperature is lower than the ideal temperature, the control system (2.12) decreases the airflow generated by the fans (2.2) in order to increase the temperature of the modular data center system (200) and save energy.

[0109] The readings received from the temperature and humidity sensor (1.5) for the actual humidity are compared with the programmed ideal humidity through the control (2.12). If the actual humidity is equal to the ideal, no action is required. If the actual humidity is greater than the ideal humidity, the control system (2.12) activates the resistor (1.9) in order to decrease the humidity of the modular data center system (200) and ensure the efficiency and safety of the equipment. If the actual humidity is less than the ideal humidity, the control system (2.12) activates the humidifier (1.8) to increase the air humidity in order to regulate the operation of the modular data center system (200) and ensure the efficiency and safety of the equipment.

[0110] The operating method developed for the operation of the precision air conditioning machine (100) is also characterized by having variable operating control according to the varying demands throughout the day of operation of the modular data center system (200). For example, at night when the ambient temperature normally decreases, and when the operation of the modular data center system (200) is normally less intense, the cooling load is reduced, and may even be met by only one circuit of the precision air conditioning machine (100), which is kept in operation, halving the energy consumption. While, during the hottest hours of the day, or when the modular data center system (200) is at full operation, it may be necessary to increase the cooling load; in this condition, both circuits of the precision air conditioning machine (100) are kept in operation.

[0111] All this adjustment of switching on and off circuits of the precision air conditioning machine (100) is carried out automatically, through the control system, in order to meet the requirements of instantaneous operation, and in this way allow the greatest possible energy efficiency.
