Description

Technical Field

[0001] This utility model relates to the field of intelligent ventilation and energy saving in BBU cabinets, and in particular to an intelligent ventilation and energy saving system for BBU cabinets. Background Technology

[0002] Data centers use a closed hot aisle cooling system. The principle is as follows: cool air flows through the IT equipment, absorbs heat, and concentrates in the hot aisle. It is then drawn back into the system by precision air conditioning for further cooling before being returned to the data center. Due to the high return air temperature, the evaporation temperature of the air conditioner is increased, resulting in higher cooling performance compared to conventional cooling methods. However, other drawbacks exist:

[0003] 1. The heat generated by IT equipment needs to be handled by air conditioning, resulting in high energy consumption;

[0004] 2. Enclosing all hot passages is costly;

[0005] 3. All return air from the air conditioner is drawn from the hot aisle, which has large ductwork and affects the space of the computer room;

[0006] 4. The temperature inside the hot aisle is high, making it inconvenient for personnel to maintain and repair IT equipment inside;

[0007] 5. Most of the IT equipment in the computer room is not arranged in a standardized manner, making it difficult to close off hot aisles. Utility Model Content

The hot air in the cabinet is discharged to the outside in time through the exhaust duct. At the same time, the cold air outside is purified by the filter and then replenished into the computer room.

[0040] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Please refer to Figure 1 This utility model provides an intelligent ventilation and energy-saving system for BBU cabinets, including a computer room 1, a fresh air intake mechanism 2, a heat dissipation and exhaust mechanism 3, a cabinet temperature and humidity sensor 6, an outdoor temperature and humidity sensor 7, and a PLC controller 8.

[0042] BBU cabinet 4 is installed in computer room 1. The hot air surface of BBU cabinet 4 is enclosed and connected to heat dissipation and exhaust mechanism 3 through exhaust duct 5.

[0043] The cabinet temperature and humidity sensor 6 is installed on the BBU cabinet 4 to monitor the temperature and humidity of the BBU cabinet 4;

[0044] The outdoor temperature and humidity sensor 7 is installed outside the computer room 1 to monitor the outdoor temperature and humidity;

[0045] The fresh air intake mechanism 2, the heat dissipation and exhaust mechanism 3, the cabinet temperature and humidity sensor 6, and the outdoor temperature and humidity sensor 7 are all electrically connected to the PLC controller 8.

[0046] During operation, when the PLC controller 8 detects that the temperature inside the BBU cabinet 4 is ≥30℃ (adjustable) through the cabinet temperature and humidity sensor 6, and the outdoor temperature detected by the outdoor temperature and humidity sensor 7 is 5℃ lower than the temperature inside the cabinet (adjustable), the exhaust electric damper 32 and the fresh air electric damper 24 open, the main exhaust fan starts running, and the hot air inside the cabinet is promptly exhausted to the outside through the exhaust duct 5. At the same time, the cold air from outside is purified by the filter and replenished into the computer room 1. Together with part of the air conditioning in the computer room 1, the indoor temperature is maintained within a suitable range.

[0047] In this embodiment, the fresh air intake mechanism 2 includes an air intake duct 21, a fresh air electric valve 24, and a filter screen 23;

[0048] Air intake duct 21 is installed on the side wall of machine room 1;

[0049] The filter screen 23 and the fresh air electric valve 24 are installed sequentially inside the air inlet duct 21.

[0050] In this embodiment, the heat dissipation and ventilation mechanism 3 includes a heat dissipation pipe 31, an exhaust electric valve 32, an exhaust fan 33, and a check valve 34;

[0051] Heat dissipation pipe 31 connects to exhaust pipe 5;

[0052] The exhaust electric damper 32, the exhaust fan 33, and the check valve 34 are sequentially installed inside the heat dissipation pipe 31;

[0053] Two sets of exhaust fans 33 are installed inside the heat dissipation pipe 31;

[0054] The two sets of exhaust fans 33 are a main exhaust fan and a standby exhaust fan. The check valve 34 is set to prevent airflow short circuit when the exhaust fan 33 is started alone. At the same time, the main exhaust fan and the standby exhaust fan can rotate to work according to the equipment time.

[0055] In this embodiment, waterproof louvers 22 are installed on both the air inlet duct 21 and the heat dissipation duct 31.

[0056] In this embodiment, a pressure relief port is installed on the exhaust duct 5. When the outdoor temperature monitored by the outdoor temperature and humidity sensor 7 is higher than the cabinet temperature monitored by the cabinet temperature and humidity sensor 6 by -5℃ (which can be set), the exhaust fan stops running, and the exhaust electric air valve 32 and the fresh air electric air valve 24 are closed. At this time, the hot air in the cabinet is discharged into the computer room 1 through the pressure relief port and cooled by the air conditioner of the computer room 1.

[0057] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
