Multi-cold source modular regional cooling energy-saving system of data center and control system of system

Abstract

The invention relates to a multi-cold source modular regional cooling energy-saving system of a data center and a control system of the system. The system comprises an air sending system, an air return system and a regional heat exchange system. By integrating a multi-air duct heat exchange system, an evaporation and dried cooling system and a compressed refrigerating system and by switching control of different modes, high-efficiency cooling of a machine room server cabinet of the data center is achieved, and the safety level of the data center is improved; and energy saving and multi-mode intelligent control are achieved according to dry-bulb temperature and wet-bulb temperature of outdoor air, a machine room air sending temperature, an air return temperature, machine room air data acquisition and draught fan frequency change, and the system is high in automation and is accurate and reliable.

Description

technical field [0001] The invention relates to a data center cooling system, and specifically discloses a data center multi-cold source modular partition cooling energy-saving system and a control method. Background technique [0002] Due to the heat dissipation of a large number of server cabinets in the data center, compared with traditional buildings, the heat dissipation intensity of the indoor servers is higher. If the cooling cannot be effectively cooled, the servers will overheat and shut down; on the other hand, the outdoor air Containing acidic compounds such as dust or sulfur will cause corrosion and damage to servers or wires. Therefore, the outdoor air quality does not meet the requirements of the data center, there is a certain risk of pollution or corrosion, and the natural cooling source of the outdoor air cannot be directly used. On the other hand, in some areas, the relative humidity of the outdoor air is relatively low. The wet-bulb temperature of the air...

[0002] Due to the heat dissipation of a large number of server cabinets in the data center, compared with traditional buildings, the heat dissipation intensity of the indoor servers is higher. If the cooling cannot be effectively cooled, the servers will overheat and shut down; on the other hand, the outdoor air Contains acidic compounds such as dust or sulfur, which will cause corrosion and damage to servers or wires

Therefore, the outdoor air quality does not meet the requirements of the data center, there is a certain risk of pollution or corrosion, and the natural cooling source of the outdoor air cannot be directly used. On the other hand, in some areas, the relative humidity of the outdoor air is relatively low. The wet-bulb temperature of the air is also relatively low. The indoor air at high heat temperature exchanges heat with the air at the low-temperature outdoor wet-bulb temperature. Compared with the outdoor dry-bulb temperature air, the cooling temperature difference increases, and the heat transfer effect is enhanced, which can take away The more outdoor cooling capacity, the utilization time of the outdoor natural air cooling source will increase
