Machine room temperature control method and system based on distributed optical fiber temperature measurement

Abstract

The invention relates to a machine room temperature control method and system based on distributed optical fiber temperature measurement. The system comprises an optical fiber temperature collecting module, an environment temperature deviation coefficient module, a power coefficient obtaining module, a temperature control factor module and a feedback control module. According to the machine room temperature control method and system based on the distributed optical fiber temperature measurement, the optical fiber temperature collecting module is used for measuring the environment temperature of cabinets in a machine room, the environment temperature deviation coefficient corresponding to the cabinets is calculated, an air conditioner is endowed with the temperature control factor in combination of the real-time power of the air conditioner, feedback control is conducted, and the cabinet environment temperature is kept dynamic balance at the preset standard temperature position; and differentiated control over the different cabinets is achieved, and the machine room refrigeration energy consumption is reduced as much as possible.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a temperature control method and system for a computer room based on distributed optical fiber temperature measurement. Background technique [0002] For the data center computer room, in order to ensure the normal operation of the equipment in it, the internal ambient temperature must be kept below a certain threshold (that is, the high temperature threshold, such as 30°C). If the temperature is not controlled, the temperature will continue to rise. [0003] In order to maintain the ambient temperature, it is necessary to use an air conditioner to cool the room. Usually, multiple air conditioners are installed in the computer room, which are respectively deployed corresponding to one or more groups of cabinets. When the temperature in the equipment room reaches the set threshold (for example, 2-3°C lower than the high temperature threshold), start the air condition...

AI Technical Summary

Problems solved by technology

In the existing technology, the number of temperature sensors installed in the computer room is limited and cannot cover the entire computer room, so it is impossible to know the temperature distribution of the computer room

For example, the operation control of the air conditioner in the computer room is only based on the temperature of individual points, so the cooling is stopped when there is a temperature heat island, which affects the operation of the equipment in the high temperature area; or continuous cooling is used to reduce the temperature of the entire area, wasting a lot of energy consumption
