Description

Technical Field

[0001] The utility model relates to the technical field of data center air conditioning and refrigeration, in particular to an intelligent auxiliary air supply device for a data center cabinet and a data center cabinet. Background Art

[0002] Traditional air conditioners for medium and small computer rooms mostly use air-cooled direct expansion air conditioners for computer rooms. Traditional air-cooled direct expansion air conditioners for computer rooms are used in computer rooms with air flow organization in the form of downward air supply and upward return air. The cooling principle for IT equipment in the computer room is that the air supply of the air conditioner is sent out from the bottom of the room by the downdraft fan. After passing through the IT equipment, the cold air absorbs the heat of the IT equipment and becomes a high-temperature airflow. It flows upward under the buoyancy of the hot air, flows to the negative pressure area above the air conditioning equipment at the top of the room, flows through the air conditioning evaporator under the suction force of the fan to cool down to low-temperature supply air, and transfers the heat to the refrigerant to be taken out of the room, completing a cycle. This design is repeated in a cycle to complete the cooling of the data center.

[0003] At present, the layout of cabinets in data centers is rather random, and new cabinets are added arbitrarily when new businesses are launched. When there are no reasonable cold and hot air flow isolation measures in the data center, there are obstructions such as structural columns, or the cabinet equipment is disorganized, it will cause local hot spot alarms in individual cabinets, and the mixing of cold and hot air flows will lead to low cooling efficiency of the air-conditioning system, causing the air-conditioning equipment to run at full load at the industrial frequency, wasting a lot of energy.

The PLC controller automatically calculates the air volume required by the IT equipment according to the weighted temperature value of the sensor, controls the number of starts and stops of the DC EC fans, and realizes on-demand air supply for each cabinet. The operating air volume, inlet and outlet air temperature and other parameters of the device are uploaded to the host computer through the communication protocol and used as input parameters for the computer room energy consumption management system, which serves as the basic basis for the energy-saving operation optimization control strategy of the computer room air conditioner.
