System and method for controlling under-floor air distribution air-conditioning fan device in machine room

Abstract

The invention discloses a system and a method for controlling an under-floor air distribution air-conditioning fan device in a machine room. The system comprises an infrared temperature measuring device used for measuring surface infrared temperature of an equipment cabinet in the machine room by infrared rays, and a control device used for regulating the air distribution speed and the air distribution period of the under-floor air distribution air-conditioning fan device when the absolute value of the difference between the surface infrared temperature and the preset surface infrared temperature of the equipment cabinet is bigger than a first preset difference value so as to enable the surface infrared temperature of the equipment cabinet to be regulated to the surface standard temperature. The system and the method dynamically regulate the air speed of the fan device at an air outlet of a ventilation floor according to the load change of the equipment in the machine room, thereby enabling the surface temperature of the equipment cabinet to be basically kept constant.

Description

technical field [0001] The invention relates to the technical field of temperature control of an electronic information system computer room, in particular to a system and method for controlling a down-flow air-conditioning fan device in a computer room. Background technique [0002] With the high integration of IT equipment in computer rooms of electronic information systems, the deviation of energy efficiency and the increasing heat dissipation of computer rooms have begun to attract intense attention from all walks of life. [0003] The air-conditioning load in the modern electronic information system computer room mainly comes from the heat generated by the main computer equipment and external auxiliary equipment, accounting for about 80-97% of the total air-conditioning load in the computer room; in the main equipment such as servers, storage, and networks, the server The share of the heat dissipation of the equipment accounts for about 80% of the total heat dissipation...

AI Technical Summary

Problems solved by technology

[0006] However, the existing air-conditioning air supply device under the ventilation panel has the problem that the air volume cannot be dynamically adjusted according to the change of the rack load. Since the computer host equipment and external auxiliary equipment are in operation, the calorific value will change at any time. The air supply device of the air conditioner under the ventilation panel maintains a constant wind speed through the air supply port. If it cannot be dynamically adjusted according to the heat generated by the equipment, the surface temperature of the equipment cabinet will inevitably fluctuate accordingly, resulting in overheating of the cabinet temperature or unnecessary excessive cooling. Situations that lead to waste of air-conditioning refrigeration energy consumption
