System for reducing machine room temperature

Abstract

The invention provides a system for reducing machine room temperature. The system comprises an air conditioner, a return air channel, an outdoor air channel, a heat transfer plate and a controller. The return air channel is used for enabling hot air in a machine room to flow back to the air conditioner. The outdoor air channel is used for enabling outdoor air to circulate in the outdoor air channel. The heat transfer plate is arranged between the return air channel and the outdoor air channel, and carries out heat exchange on the hot air in the return air channel and the outdoor air in the outdoor air channel. The controller is used for controlling the air conditioner to carry out refrigeration according to a preset condition. According to the system, the machine room temperature is reduced, the cooling load of the machine room is reduced, mechanical refrigeration operating time is shortened, the total energy consumption of a data center is reduced, and the energy saving effect is obvious.

Description

technical field [0001] The invention relates to the technical field of computer room monitoring, in particular to a system for reducing the temperature of a computer room. Background technique [0002] With the rising cost of energy and people's emphasis on green environmental protection, the demand for energy saving in data centers is becoming stronger and stronger. Under the premise of ensuring the safe and high-performance operation of IT equipment in the data center computer room, comprehensively utilize various energy-saving means to improve the energy utilization efficiency of the data center and reduce PUE (Power Usage Effectiveness, an index for evaluating the energy efficiency of the data center). In other words, energy saving and emission reduction has become one of the important goals pursued by data center infrastructure. [0003] At present, existing data centers usually use mechanical refrigeration to reduce the temperature of the return air in the computer ro...

Problems solved by technology

[0004] However, the existing methods have the following disadvantages. The precision air conditioner is used to completely reduce the return air temperature of the computer room. The air conditioning system needs to be mechanically refrigerated for most of the year, so the energy consumption is very large; the direct natural cooling of the air side is adopted. Energy-saving mode, since outdoor fresh air needs to be introduced into the computer room, the computer room will be exposed to the risk of outdoor pollutants, it is difficult to ensure the safe and stable operation of IT equipment, and the cooling effect is not good, and the cooling efficiency is low
