Closed cold channel data center with cold region and hot region

Abstract

The invention discloses a closed cold channel data center with a cold region and a hot region. A plurality of cabinets are arranged in a machine room of the data center. The machine room is divided by a floor into a machine room space above the floor and a refrigeration equipment space below the floor. The cabinets are arranged on the floor in rows, and each row of cabinets is provided with a closed cold channel. Refrigeration equipment is arranged in the refrigeration equipment space, wherein the refrigeration equipment comprises a hot air inlet and a cold air outlet, the hot air inlet is communicated with the machine room space, and the cold air outlet is communicated with one corresponding closed cold channel. According to the closed cold channel data center with the cold region and the hot region, the refrigeration equipment does not occupy floor space of the machine room so that all the floor space can be used for the placement of the cabinets as needed; moreover, the machine room is divided into the cold region and the hot region, inlet air temperature of the refrigeration equipment is raised, therefore, heat exchange efficiency is improved, and the effect of energy conservation is achieved; meanwhile, the closed cold channels are adopted to enable the refrigeration equipment to supply cold air to each row of cabinets, the cold air of the refrigeration equipment is distributed to each cabinet after being transmitted to the closed cold channels, and therefore the closed cold channel data center can be adapted to various models of cabinets.

Description

technical field [0001] The invention belongs to the technical field of spatial arrangement of cabinets and refrigeration equipment in a communication data center. Background technique [0002] With the continuous development of Internet services, the demand for data centers is increasing. In order to save space, the development of data centers is developing in the direction of high density and large scale; traditional data center solutions, refrigeration equipment and IT equipment, Generally, they are placed on the same floor. Refrigeration equipment occupies more than 30% of the computer room area. In addition, some equipment maintenance space makes the space available for IT equipment in the computer room greatly reduced. [0003] A large part of domestic data centers are built in large and medium-sized cities. Due to the progress of urbanization, land resources in large and medium-sized cities are very precious. Therefore, how data centers can save space and reduce costs ...

Problems solved by technology

[0004] In addition, in terms of the layout of the computer room, in many traditional solutions, hot and cold air is mixed before entering the cabinet equipment, or returning to the refrigeration equipment. In order to control the temperature of the cabinet, the outlet air temperature of the refrigeration equipment is designed to be relatively low. , so as to ensure that the air inlet temperature of the cabinet can be met after being mixed with hot air; at the same time, because part of the air outlet is short-circuited and directly enters the refrigeration equipment, the return air temperature is low, so the outlet air temperature is designed to be relatively low and the return air temperature is low These two items will increase the energy consumption of the computer room, and the energy saving performance of the computer room is not good.
