Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] The present invention is based on an evaporative cooling air-conditioning system for data centers with closed hot aisles, such as figure 1 As shown, it includes a hot air channel 22 arranged at the top of the data room, a cold air channel 19 arranged at the bottom of the data room, and an indirect evaporative cooling air-conditioning unit 16 arranged outside the data room. The two ends of the indirect evaporative cooling air-conditioning unit 16 are respectively It communicates with the hot air channel 22 and the cold air channel 19; the hot air in the data room is concentrated in the hot air channel 22 on the upper part of the machine room, and the hot air is cooled by the indirect evaporative cooling air conditioning unit 16 to become cold air, and then the cold air enters the data room through the cold air supply duct 17 Passage 19,...

The invention discloses an evaporative cooling air conditioning system for a data center based on a closed heat channel. The system comprises a hot air channel, a cold air channel and an indirect evaporative cooling air conditioning unit arranged outside a data center machine room, wherein the hot air channel and the cold air channel are arranged in the data center machine room; the two ends of the indirect evaporative cooling air conditioning unit communicate with the hot air channel and the cold air channel correspondingly; the system further comprises a plurality of server cabinet units arranged in the data center machine room, each server cabinet unit is composed of two server cabinet units, the air outlet sides of the two server cabinet units in each server cabinet unit are oppositelyarranged, and a closed heat channel is formed between the air outlet sides of the two server cabinets; and each closed heat channel communicates with the hot air channel, and a closed cold channel isformed between every two adjacent server cabinet units. According to the system, the evaporative cooling air conditioning system for the data center can fully make use of the outdoor dry air, so thatthe annual running cost of the air conditioning system is greatly reduced, and the system can stably supply cold to the data center machine room in a whole year.
Description
technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to an evaporative cooling air-conditioning system for a data center based on a closed hot aisle. Background technique [0002] With the explosive growth of information volume and the continuous deepening of information applications, data centers provide convenient intelligent computing processing and information storage functions. However, in the early data centers, due to the characteristics of the data computer room and the limitation of refrigeration technology, the energy consumption of the computer room was too high, making the energy consumption of the air conditioner in the computer room the most important part of the total energy consumption of the data center. [0003] Today, the massive construction of data centers has also prompted people to have a new understanding of the data room, and the energy-saving and environmentally friendly refrige...
