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

Embodiment Construction
[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0037] The system and method for controlling the blower device of the downflow air conditioner in the computer room described in the specific embodiments of the present invention, through real-time monitoring and measurement of the surface infrared temperature of the equipment cabinet in the computer room, dynamically adjust the downflow air conditioner according to the change of the surface infrared temperature The air supply speed of the fan device enables the air supply volume blown out by the air conditioner in the machine room through the ventilation floor to be dynamically adjusted according to the change of the rack load, so as to maintain a basically constant temperature on the surface of the equipment cabinet and meet the ideal start-up opera...

The present invention disclosed a system and method of controlling the air -conditioning air -conditioning fan device in the machine room.When the surface infrared temperature and the pre -set equipment cabinet surface standard temperature difference is greater than the absolute value of the first preset, the air supply and wind speed and air supply cycle of the air -conditioning air -conditioning fan device are adjusted.The surface infrared temperature of the device cabinet is adjusted to the standard temperature of the surface.The system and method dynamically adjust the wind speed of the fan device at the ventilation of the ventilation floor according to the load changes of the equipment in the computer room, so that the surface temperature of the device cabinet can be kept basically 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...
