High-density computer room renovation project case

A department in Zhejiang Province renovated the computer room with an area of about 500 square meters, and there are currently 200 cabinets installed in the computer room, the cabinets are arranged in 6 rows, no hot and cold channels are closed, and the IT load in the computer room is 5kW, and the computer room is located on the fourth floor of the building. The user's existing data center infrastructure and IT equipment in the cabinet can no longer meet the growing computing and storage needs, and it is necessary to transform the low-density cabinet into a high-density cabinet.

1. Transformation ideas

The 200 5kW cabinets in the original computer room have been transformed into 40 25kW high-density cabinets, and 4 high-density double-row micro-modules (10 cabinets per module) can be arranged in the computer room after the transformation. The air conditioning configuration scheme is inter-column precision air conditioning or cold plate liquid cooling air conditioning.

2. Inter-column precision air conditioning scheme

According to the design scheme, 4 identical double-row micro-modules are deployed, and each micro-module is equipped with 10 (8+2) inter-column precision air conditioners, with a total of 40 (32+8) units. Inter-column precision air conditioner single cooling capacity: 35kW; Rated air volume: 8000m³/h; The air conditioning equipment controls the air supply at 22°C and the return air at 35°C. the back of the air conditioner is returned to the air, and the front is ventilated; The total number is 40 units. The default position of each micromodule is 10 IT racks, the IT rack load is 25kW/rack, and the computer room has a total of 40 IT racks. The micromodule closes the cold aisle with a width of 1.8m. The layout of the scheme is as follows:

The specific details of the new air conditioning equipment of the inter-column precision air conditioning scheme are as follows:

The details of the new power distribution equipment of the inter-column precision air conditioning scheme are as follows:

Summary of cabinet power distribution adjustments:

Note: The number and selection of transformers, UPS, and low-voltage cabinets remain unchanged.

Summary of air conditioning distribution adjustment of inter-column layout scheme:

Note: The number and selection of special transformers, UPS, and low-voltage cabinets for air conditioning should be comprehensively considered according to other loads.
