Description

Technical Field

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

[0002] As the internet enters the cloud era, data center construction is booming. Building efficient, energy-efficient, and green data centers, while minimizing energy efficiency and reducing PUE (Power Usage Effectiveness) values, has become a top priority for legacy data centers.

[0003] Currently, data centers using room-level upward-distributed air conditioners are relatively new, and a large proportion of the upward-distributed air is returned from the room-level air conditioners. As servers become smaller and denser, the heat generated by individual cabinets is increasing. This inevitably leads to areas where the air conditioning cannot reach, and even the use of ducted air supply has difficulty addressing this issue. While the use of half-cabinets, connecting them to ducts, can minimize cooling loss, the ducts cannot adjust the air flow, and even if the half-cabinets have air flow control, they may not be able to provide sufficient cooling in high-heating cabinets. This inevitably results in equipment in areas with low heat generation being overcooled and equipment in areas with high heat generation being overheated.

[0004] If a cabinet with high heat generation is close to the air conditioner, the return air temperature of the air conditioner will be too high, and the compressor will not stop running, increasing energy consumption; if equipment with low heat generation is close to the air conditioner, the return air temperature will be low, and the compressor will start and stop frequently, affecting the service life of the compressor; at the same time, the equipment in the cabinet with high heat generation will not get enough cooling capacity, causing local overheating or even downtime, resulting in huge economic losses.
