Description

Technical Field

[0001] The utility model specifically relates to a fresh air device for a communication machine room. Background Technique

[0002] With the rapid development of the information age, data centers play an increasingly important role. However, the operating costs and energy consumption of data centers also increase accordingly. In order to improve the efficiency of data centers and reduce energy consumption, it has become an urgent need to reduce the Power Usage Effectiveness (PUE) value of data centers. Among them, the air conditioning system is one of the largest energy-consuming parts of data centers. Therefore, optimizing the air conditioning system is the key to reducing the PUE value.

[0003] For example, a certain data center uses 4 column air conditioners with a power of 25KW each to generate cooling capacity to cool the equipment, and it operates 24 hours a day, 365 days a year, consuming a large amount of electric energy and incurring huge costs. The most cost-saving method is not to use air conditioners to cool the equipment. This data center is located in the north, where winter comes earlier and the weather is colder. If the cold outdoor air can be introduced into the room to cool the equipment, as long as the cold air introduced into the room has the same characteristics of "large air volume and small enthalpy difference" as the dedicated air conditioner in the machine room, the air conditioner in the room can be turned off to save electricity.

[0004] The fresh air system is an independent air treatment system composed of a supply air system and an exhaust air system. It is divided into two types: ducted fresh air system and ductless fresh air system. The ducted fresh air system consists of a fresh air fan and duct fittings. The outdoor air is purified by the fresh air fan and introduced into the room, and the indoor air is discharged through the duct; the ductless fresh air system consists of a fresh air fan, and the outdoor air is also purified by the fresh air fan and introduced into the room. Relatively speaking, the ducted fresh air system is more suitable for industrial or large-area office areas due to its large engineering volume, while the ductless fresh air system is more suitable for home use because of its convenient installation.

[0005] According to the existing cabinet layout in the data center, the communication equipment dissipates a large amount of heat and requires a large amount of cooling capacity to cool the communication equipment. However, the column air conditioner has too high a power and too small a cooling capacity, wasting a lot of electric energy and resulting in huge operating costs for the data center. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a fresh air device for a communication machine room aiming at the above-mentioned deficiencies existing in the prior art, transporting the cold outdoor air into the machine room through a ventilation duct, and then the indoor air conditioner can be turned off to save electricity and play the role of reducing costs and increasing efficiency.

[0007] The present utility model provides a fresh air device for a communication machine room. The fresh air device for the communication machine room includes an air inlet, an axial flow fan, an air duct, and an air outlet which are arranged in sequence. Among them, a shock absorption part is arranged on the part of the air duct close to the axial flow fan. The air inlet, the axial flow fan, and the shock absorption part are arranged outdoors, and the air duct penetrates through the wall where the indoor and outdoor are connected. The air outlet is arranged indoors.

[0009] Optionally, an air inlet filtering device is arranged at the end of the air inlet far from the air duct. An air outlet filtering device is arranged at the end of the air outlet far from the air duct.

[0010] Optionally, the fresh air device for the communication machine room further includes a temperature controller and a temperature sensor arranged on the air outlet filtering device. The temperature controller is electrically connected to the axial flow fan and the temperature sensor respectively. The temperature sensor is used for measuring the temperature at the air outlet and sending the measured temperature data of the air outlet to the temperature controller. The temperature controller is used for receiving the temperature data of the air outlet from the temperature sensor, comparing the received temperature data of the air outlet with a preset value, and controlling the operation of the axial flow fan according to the comparison result.

[0011] Optionally, the fresh air device for the communication machine room further includes a gateway circuit breaker, and the gateway circuit breaker is electrically connected to the axial flow fan. The gateway circuit breaker is used for real-time monitoring of the power consumption information of the axial flow fan, counting the energy consumption of the axial flow fan, carrying out fault early warning, fault location and fault analysis on the axial flow fan, and reporting the power consumption information of the axial flow fan to the user.

[0012] Optionally, the caliber of the part of the air duct close to the shock absorption part is smaller than the caliber of the part of the air duct far from the shock absorption part.

[0013] Optionally, heat preservation cotton is arranged on the part of the outer wall of the air duct indoors.

[0014] Optionally, a slope inclined downward from indoors to outdoors is arranged on the lower wall inside the air duct in the lower half of the part where the indoor and outdoor are connected.

[0027] To enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by various orientation terms is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0029] Some embodiments of the present utility model provide a fresh air device for a communication machine room, such as Figure 1 As shown, the fresh air device of the communication machine room includes an air inlet 1, an axial flow fan 2, an air duct 3, and an air outlet 4 arranged in sequence. Among them, a shock absorption part 31 is provided on the part of the air duct 3 close to the axial flow fan 2. The air inlet 1, the axial flow fan 2, and the shock absorption part 31 are arranged outdoors, and the air duct 3 penetrates the wall 10 where the indoor and outdoor are connected; the air outlet 4 is arranged indoors.

[0030] It can be understood that in the case of relatively low outdoor temperature, the temperature inside the communication machine room is very likely to be higher than the outdoor temperature. Thus, the axial flow fan 2 can be turned on to suck the cold air outdoors from the air inlet 1 and send it through the air duct 3 to the air outlet 4 arranged indoors. In this way, the cold air outdoors can enter the communication machine room indoors, and the indoor temperature of the communication machine room can be reduced.

[0031] Exemplarily, the axial flow fan 2 can be a high-temperature resistant, oil-proof, and moisture-proof axial flow fan, which has the characteristics of large power, large air volume, fast rotation speed, high insulation level, fast rotation speed, etc., and meets the cooling capacity requirements of the data center.

[0032] It can be understood that by providing the shock absorption part 31 on the part of the air duct 3 close to the axial flow fan 2, it can prevent the axial flow fan from vibrating continuously during operation and damaging the air duct, and has the functions of shock absorption, ventilation, and waterproofing. The part of the air duct 3 indoors can be supported by brackets and the cabinets in the communication machine room, without affecting the use of the cabinets and equipment.

[0033] Exemplarily, as Figure 1 shown, the outlet of the air outlet 4 faces downward, and the air outlet 4 can be arranged in the middle of two rows of cabinets. In this way, the cold air from the air inlet 1 can be directly sent to the inspection cabinets in the row, and the cooling effect is better.

[0034] In some embodiments, as Figure 1 shown, the caliber of the end of the air inlet 1 far from the air duct 3 is larger than the caliber of the end of the air inlet 1 close to the air duct 3, and / or the caliber of the end of the air outlet 4 far from the air duct 3 is larger than the caliber of the end of the air outlet 4 close to the air duct 3.

[0035] Understandably, the diameter of the end of the air inlet 1 away from the air duct 3 is larger than that of the end of the air inlet 1 close to the air duct 3, which can allow more cold air to enter the fan 3 from the outside, and it is easier to install or replace the filtering device at the end of the air inlet 1 away from the air duct 3. The diameter of the end of the air outlet 4 away from the air duct 3 is larger than that of the end of the air outlet 4 close to the air duct 3. When the cold air outside reaches the lowermost end of the air outlet 4, it can increase the heat exchange area, improve the cooling efficiency, and it is easier to install or replace the filtering device at the end of the air outlet 4 away from the air duct 3.

[0036] In some embodiments, as Figure 2 shown, an air inlet filtering device 11 is provided at the end of the air inlet 1 away from the air duct 3. An air outlet filtering device 41 is provided at the end of the air outlet 4 away from the air duct 3.

[0037] Understandably, the air inlet filtering device 11 can filter out dust or mosquitoes in the outdoor cold air at the air inlet 1, and the air outlet filtering device 41 can further filter dust or mosquitoes in the cold air.

[0038] In some embodiments, as Figure 3 shown, the fresh air equipment in the communication machine room further includes a temperature controller 5 and a temperature sensor 42 provided on the air outlet filtering device 41. The temperature controller 5 is electrically connected to the axial flow fan 2 and the temperature sensor 42 respectively. The temperature sensor 42 is used to measure the temperature at the air outlet 4 and send the measured temperature data of the air outlet 4 to the temperature controller 5. The temperature controller 5 is used to receive the temperature data of the air outlet 4 from the temperature sensor 42, compare the received temperature data of the air outlet 4 with a preset value, and control the operation of the axial flow fan 2 according to the comparison result.

[0039] Understandably, the temperature sensor 42 can measure the temperature at the air outlet 4, that is to say, the temperature sensor 42 can measure the indoor temperature of the communication machine room. After receiving the temperature data of the air outlet 4 from the temperature sensor 42, the temperature controller 5 compares the received temperature data of the air outlet 4 with a preset value (such as realizing data comparison through a comparison circuit), and controls the operation of the axial flow fan 2 according to the comparison result. For example, when the temperature data at the air outlet 4 is higher than the preset value, the axial flow fan is turned on. It can also turn off the axial flow fan when the temperature data at the air outlet 4 is lower than the preset value and the axial flow fan is in the working state, which can further save electric energy. Understandably, different communication machine rooms have different sensitivities to the ambient temperature, and the preset value can be set according to the situation of the communication machine room.

[0040] Exemplarily, the temperature sensor 42 can also be a temperature and humidity sensor that can measure temperature and humidity. The communication machine room also has certain requirements for environmental humidity. An overly dry environment is prone to generating static electricity. The temperature and humidity sensor can transmit the monitored temperature data and humidity data to the dynamic environment detection platform in the communication machine room. When the dynamic environment detection platform detects that the humidity in the communication machine room is lower than the preset humidity value, it can send an alarm message to remind the staff to humidify the machine room.

[0041] It can be understood that in the related art, both the air conditioning system and the fresh air system can be configured with temperature controllers. The temperature controller 5 in the embodiments of the present invention can be any temperature controller in the related art that can implement the above functions. For example, the temperature controller can be an intelligent temperature controller with the brand name Xifa and the model number SV-201B-4(1) available on the market.

[0042] In some embodiments, as Figure 4 shown, the fresh air equipment in the communication machine room further includes a gateway circuit breaker 6, and the gateway circuit breaker 6 is electrically connected to the axial flow fan 2. The gateway circuit breaker 6 is used to monitor the power consumption information of the axial flow fan 2 in real time, count the energy consumption of the axial flow fan 2, perform fault early warning, fault location and fault analysis on the axial flow fan 2, and report the power consumption information of the axial flow fan 2 to the user.

[0043] It can be understood that the gateway circuit breaker 6 can perform real-time monitoring, statistics, fault early warning, fault analysis and fault reporting of the energy consumption of various electrical equipment, so that the staff can understand the specific operation conditions of each electrical equipment.

[0044] Exemplarily, in the embodiments of the present invention, the gateway circuit breaker 6 can be an intelligent gateway circuit breaker in the related art that can implement the above functions. For example, the gateway circuit breaker can be an intelligent gateway circuit breaker with the brand name Sankoujing and the model number NZ3-4PNC063A available on the market.

[0045] In the related art, the intelligent gateway circuit breaker can have the following functions:

[0046] 1 Energy consumption statistics:

[0047] Power consumption metering: Real-time collection of power energy consumption data, classification, sub-item and sub-area statistics of energy consumption information, and users can query and trace historical data.

[0048] Energy consumption report: According to the monitoring and management status of the system platform, provide a complete operation report for customers, automatically generated by the system, and can provide weekly, monthly, annual reports and custom time reports.

[0049] The platform also provides statistics on fault data. In the alarm log management, classification statistics can be performed according to front-end detectors and hosts to grasp the detailed alarm situation and the statistical display of the handling of faults. At the same time, the export of fault logs is supported.

[0050] 2 Real-time monitoring of electricity consumption information:

[0051] Real-time collection of electric energy consumption data;

[0052] Real-time early warning and alarm statistics: Real-time statistics on the types and quantities of early warning and alarm types such as overvoltage early warning, overload early warning, overcurrent early warning, temperature early warning, leakage early warning, undervoltage early warning, humidity early warning, spark alarm, device offline, power failure alarm, phase loss alarm, and surge alarm in electricity use safety;

[0053] Device online statistics: Support for the number of online, offline, and proportion of front-end IoT devices;

[0054] Device alarm statistics: Support for statistical analysis of the alarm quantities of the top 10 devices in the recent 24 hours, recent 7 days, recent 30 days, and recent 6 months;

[0055] Fault type statistics: Support for statistical analysis of the alarm statistics of the top 10 devices in the recent 24 hours, recent 7 days, recent 30 days, and recent 6 months, and display the specific quantities and proportions;

[0056] Circuit electricity consumption statistics: Support for trend comparison analysis of each sub-circuit in the current period, same period, and month-on-month in the current day, recent 24 hours, recent 7 days, recent 30 days, and recent 6 months;

[0057] Unit electricity consumption statistics: Support for statistical and comparative analysis of the total electricity consumption of the electricity consumption unit in the current day, recent 24 hours, recent 7 days, recent 30 days, and recent 6 months;

[0058] Real-time alarm display: Support for scrolling display of the recent 30 electricity use alarm events.

[0059] 3 Hidden danger early warning:

[0060] When an anomaly is detected, the real-time alarm information is pushed to the platform end, and the platform can choose to display it in a pop-up window or not.

[0061] The intelligent miniature circuit breaker (intelligent gateway circuit breaker) has the ability to detect electricity use anomalies and faults of the power supply lines corresponding to the electricity use equipment under its jurisdiction, such as equipment power outage, equipment power-on, power overload, overloading, undervoltage, phase-to-phase short circuit, equipment leakage, and arc fault. The intelligent module collects the electricity use anomaly and fault information sent by each intelligent miniature circuit breaker, conducts comprehensive analysis, and then performs corresponding processing to achieve the automatic control of electricity use of electrical equipment.

[0062] 4 Full-cycle fault analysis:

[0063] Fault warning (beforehand): Utilize the powerful data monitoring function to monitor in real time data such as voltage, current, power, leakage current, and line temperature in the power consumption circuit. When there is an abnormal trend in the circuit, give a timely warning to avoid the occurrence of power consumption accidents.

[0064] Fault location (during the event): When a power consumption fault occurs, the operation and maintenance personnel can be notified in a timely manner of the time of the fault, the location of the fault, and the cause of the fault. The platform can automatically generate a dispatching process for the fault and solve the remote power consumption maintenance in a real-time and efficient manner.

[0065] Fault analysis (afterwards): The solution can record the relevant data at the moment of the fault, which is used for the accurate analysis of the cause of the fault to guide the operation and maintenance personnel for accurate maintenance, avoid the occurrence of repeated faults, utilize the powerful storage function of the cloud platform to analyze and learn the big data of the power consumption data, predict the power consumption hidden dangers, and avoid the occurrence of power consumption accidents.

[0066] 5 Remote (mobile phone) control of power consumption automation.

[0067] The intelligent circuit breaker (intelligent gateway circuit breaker) can monitor in real time the power consumption information of each line, such as current, voltage, leakage current, power, and temperature, can monitor equipment faults in real time, and remind the management personnel by means of APP push, SMS, etc. before an accident occurs for fault warning, improve power consumption safety, and reduce maintenance costs.

[0068] Through the intelligent circuit breaker (intelligent gateway circuit breaker), the real-time data of the power consumption of the mobile information device, the power consumption warning analysis, and the real-time alarm information are uploaded to the supervision platform and the mobile client of the administrator in a timely manner, which is convenient for the management personnel to query the power consumption data in real time and conduct intelligent power consumption control, so as to achieve the purpose of saving energy.

[0069] The management personnel can realize the real-time monitoring of the total energy consumption and the classified and itemized energy consumption of the communication base station, compare the historical power consumption data, and conduct energy consumption analysis, which can provide a big data analysis basis for accurately studying the real-time energy consumption of the communication base station, so as to improve the operation and maintenance efficiency and the intelligent level.

[0070] Exemplarily, as Figure 5 shown, the fresh air equipment in the communication machine room can include a temperature controller 5 and a gateway circuit breaker 6. The temperature controller 5 is connected between the gateway circuit breaker 6 and the axial flow fan 2, and the temperature controller 5 is also electrically connected to a temperature sensor 42 provided on the air outlet filter device 41.

[0071] In some embodiments, as Figures 1 to 5 shown, the diameter of the part of the air duct 3 away from the shock absorption part 31 is larger than the diameter of the part of the air duct 3 close to the shock absorption part 31, and the diameter of the part of the air duct 3 away from the shock absorption part 31 is larger than the diameter of the shock absorption part 31.

[0072] It can be understood that the larger the diameter of the air duct 3 is, the greater the air flow therein is, and the smaller the diameter of the shock absorbing part 31 is, the better the shock absorbing effect is and the lower the cost is. For example, the shock absorbing part 31 can be a hose.

[0073] In some embodiments, Figure 6 As shown, the indoor portion of the outer wall of the air duct 3 is provided with thermal insulation cotton 7.

[0074] It can be understood that the thermal insulation cotton 7 is arranged on the outer wall of the indoor air duct 3, which can reduce the water droplets generated due to the large temperature difference between indoor and outdoor.

[0075] Exemplarily, the outer wall of the indoor air duct 3 can be completely wrapped with thermal insulation cotton.

[0076] In some embodiments, Figure 7 As shown, the lower wall inside the air duct 3 is provided with a slope 32 which slopes downward from the indoor to the outdoor at the lower half of the wall which passes through the indoor and outdoor interfaces.

[0077] It can be understood that when the temperature difference between indoor and outdoor is large, cold air enters the air duct 3 through the air inlet 1, and condenses into water droplets at the indoor temperature. If there are many water droplets, they may converge into water flow. The slope 32 can make these condensed water droplets or converged water flow flow along the slope 32 to the bottom of the slope 32 without flowing back into the room.

[0078] In some embodiments, Figure 8 As shown, the slope 32 includes a first slope 33 and a second slope 34 arranged in sequence from indoors to outdoors, and the angle between the second slope 34 and the horizontal line is smaller than the angle between the first slope 33 and the horizontal line.

[0079] Understandably, if Figure 8 As shown, the angle between the second slope 34 and the horizontal line (i.e., α) is smaller than the angle between the first slope 33 and the horizontal line (i.e., β), which means that the first slope 33 has a greater inclination and better diversion effect, and the condensed water droplets or the converged water flow are more likely to flow along the first slope 33 to the second slope 34, and are not easy to gather on the first slope 33. After the condensed water droplets or the converged water flow flows on the second slope 34, they can flow along the second slope 34 to the lower part of the second slope 34.

[0080] Exemplarily, the angle between the second slope 34 and the horizontal line is greater than 5°. In this way, the second slope 34 can have a better guiding effect.

[0081] In some embodiments, Figure 9 As shown, the length of the first slope 33 is smaller than the length of the second slope 34 .

[0082] Understandably, if Figure 9As shown, since the angle between the second slope 34 and the horizontal line is smaller than the angle between the first slope 33 and the horizontal line, and the length of the first slope 33 is shorter than the length of the second slope 34, it indicates that the first slope 33 is steeper while the second slope 34 is gentler. That is, the height difference between the two ends of the first slope 33 (for example, d) is larger. The larger the value of d, the better the flow guiding effect of the first slope 33, the less likely the water flow is to accumulate on the first slope 33, and the less likely it is to flow back into the room.

[0083] Exemplarily, the height difference between the two ends of the first slope 33 is at least 5 cm.

[0084] It can be understood that the fresh air device for a communication machine room provided by the embodiment of the present invention can replace the air conditioner when the outdoor temperature is relatively low, provide continuous cold air for the communication machine room, achieve the effect of cooling the communication machine room, and compared with the air conditioner in the machine room, the power consumption of the fresh air device for a communication machine room provided by the embodiment of the present invention is lower, which can reduce the energy consumption of the communication machine room, reduce the operation cost of the communication machine room, and lower the PUE of the data center.

[0085] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
