Sealed hot channel-full air returning dried-air energy central air conditioning system for data center

Abstract

The invention discloses a sealed hot channel-full air returning dried-air energy central air conditioning system for a data center. The sealed hot channel-full air returning dried-air energy central air conditioning system comprises a dried-air energy central air conditioning unit; the dried-air energy central air conditioning unit is connected with the data center through an air returning pipe and can recycle return air in the data center and process the return air so that the return air can become air meeting the air supply condition; and the dried-air energy central air conditioning unit is further connected with the data center through an air supply pipe, and the air meeting the air supply condition can be fed into the data center through the air supply pipe and a machine room air supply outlet. According to the sealed hot channel-full air returning dried-air energy central air conditioning system for the data center, the full year cool supply requirement of the data center can be effectively ensured, the phenomenon that disordered air distribution occurs in the data center can be avoided, and meanwhile reasonable adjustment of three operation modes can be achieved according to different weather conditions.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning systems, and in particular relates to a closed hot aisle-full return dry air energy central air-conditioning system for a data center. Background technique [0002] In the environment where the country vigorously advocates energy conservation and emission reduction, it is particularly important to save energy consumption of air conditioning systems in data centers. Some existing data center air conditioners use the air supply method under the raised floor, relying entirely on precision air conditioners to monopolize all the loads in the data center, which consumes a lot of energy. Some data centers also use the combination of fresh air and evaporative cooling technology. The advantage of this technology is that it can greatly reduce the cost of the HVAC system and reduce the PUE value. It is difficult to guarantee its cooling effect under weather conditions. [0003] The environment in ...

Some existing data center air conditioners use the air supply method under the raised floor, relying entirely on precision air conditioners to monopolize all the load in the data center, which consumes a lot of energy

Some data centers also use the combination of fresh air and evaporative cooling technology. The advantage of this technology is that it can greatly reduce the cost of the HVAC system and reduce the PUE value. It is difficult to guarantee its cooling effect under weather conditions

[0003] The environment in the data center has the characteristics of high return air temperature and large temperature difference between dry and wet bulbs. It is especially suitable for using evaporative cooling technology to process the return air to meet the requirements for cooling, humidifying and purifying the data center. Capacity increase, evaporative cooling alone cannot meet the cooling demand in the later stage, so mechanical refrigeration devices must be appropriately increased to meet the cooling demand, but the extensive use of mechanical refrigeration devices can easily lead to disordered air flow in the data center, and serious mixing of cold and hot , resulting in poor cooling
