System and method for adjusting temperature of fresh air machine room

Abstract

The invention provides a system and method for adjusting the temperature of a fresh air machine room. The system comprises a machine room, a refrigerating system, an outdoor sensor, an indoor sensor and an IDC cloud control system. The machine room is provided with the fresh air system. The IDC cloud control system is connected with all components. The outdoor sensor collects outdoor detection data, and the indoor sensor collects indoor detection data. The IDC cloud control system calculates an outdoor fuzzy integral value EVAout according to the outdoor detection data and the outdoor relevantfuzzy measure Mu (Ai), wherein the outdoor relevant fuzzy measure Mu (Ai) is obtained through historical data training. If EVAout is greater than or equal to an outdoor fuzzy integral threshold valueEVAthre, it is decided to introduce fresh air through the fresh air system according to the judgment strategy; and otherwise, the fresh air is not introduced, and the refrigerating system is started.An indoor fuzzy integral value EVAin is calculated according to the indoor detection data and the indoor relevant fuzzy measure Mu (Ai); if EVAin is greater than or equal to an indoor fuzzy integralthreshold value EVA'thre, it is decided to continuously introduce the fresh air according to the judgment strategy; and otherwise, the fresh air is not introduced, and the refrigerating system is started.

Description

technical field [0001] The invention relates to the management technology of a machine room, in particular to a system and method for adjusting the temperature of a fresh air machine room. Background technique [0002] With the technological development of mobile Internet, Internet of Things and cloud computing, as an important carrier of information, the number and scale of data centers have grown rapidly, and their energy consumption and operating costs have become increasingly prominent. According to statistics, the energy consumption of the data center mainly includes IT equipment, air-conditioning system and power supporting system, and the air-conditioning equipment generally consumes about 40% of the electric energy in the computer room. [0003] It is undoubtedly an ideal, convenient and efficient way to save energy by using natural fresh air to directly cool the computer room and reduce the working hours of the air conditioner. [0004] The basic principle of the e...

Problems solved by technology

[0009] The existing fresh air cooling scheme considers few environmental parameters of the computer room, and generally does not consider the environmental information of the computer room such as corrosion, dust, and energy consumption, which increases the security risks of the computer room and reduces the energy-saving efficiency. The influence of the interrelationship between the multi-dimensional information of the environment on whether to introduce fresh air in the end makes the energy-saving efficiency of introducing fresh air not reach the comprehensive optimum; the existing fresh air cooling schemes generally do not introduce fresh air when the quality of outdoor fresh air is heavily polluted. Fresh air, without considering the fact that indoor air corrosion can reach the standard under the condition of adding chemical filters, shortens the length of time for the introduction of fresh air throughout the year; the existing fresh air cooling scheme does not use the historical environmental data of the computer room for reference, and only relies on some real-time data as the introduction of fresh air Judgment basis
