Embodiment approach

[0100] The implementation manner of cooling the electrical equipment in the machine room through the embodiment of the present invention is as follows:

[0101] see image 3 , the temperature sensor 1 is arranged near the front and rear ends of the electrical equipment 6 in the cabinet 2, the current sensor 3 is fixed on the column of the cabinet 2, and the display device can display the temperature status in real time on the panel in front of each cabinet 2 . The air deflector 7 is arranged at the air inlet of the cabinet 2 to guide the incoming cold air to improve the cooling effect. When the working state of the electrical equipment 6 in the cabinet 2 changes, its current must change. The current sensor 3 sends the monitored current signal to the controller, and the controller outputs a control signal to the refrigeration device according to the received current signal, so as to control the refrigeration device to cool the corresponding electrical equipment 6, thereby rea...

Abstract

The invention discloses a machine room air conditioner control method and system. The method at least comprises the steps of obtaining currents of all electricity devices; according to the current change amount of the electricity devices, pre-judging changes of the heating amount of all the electricity devices; on the basis of the changes of the heating amount of the electricity devices, adjusting the local and / or whole refrigeration amount; the refrigeration amount of a refrigeration device is flexibly adjusted, and distribution refrigeration adjustment of local hot points is achieved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners in computer rooms, in particular to a control method and system for air conditioners in computer rooms. Background technique [0002] As the workplace of data processing equipment and electronic communication equipment, the data center computer room has a relatively large heat load and needs to be air-conditioned all year round. The operating cycle of the air conditioner in the computer room is relatively long, and the energy consumption is relatively large, which accounts for an increasing proportion of the operating cost of the enterprise. Specifically, the cost of cooling accounts for more than 45% of the operating costs of various data centers. [0003] With the development of electronic equipment in the direction of miniaturization and diversification of functions and the continuous improvement of its operating speed, the heat dissipation per unit area has increased signific...
