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.
