Energy saving control method and device of air conditioner at tail end of data center machine room

Abstract

The invention provides an energy saving control method and device of an air conditioner at the tail end of a data center machine room. The energy saving control method of the air conditioner at the tail end of the data center machine room comprises the steps that the temperature of the returned air of an air conditioner device at the tail end of the data center machine room is collected; according to the temperature of the returned air, the supplied water temperature increasing requirement is sent to a self-control refrigerating system of the data center machine room so that the self-control refrigerating system can increase the temperature of the chilled water of a self-control system. The temperature of the supplied water can be increased in an electric refrigerating mode, the temperature can be reduced in a natural cooling mode, the energy-saving control over the refrigerating system is achieved, control optimization is carried out on the air conditioner at the tail end, the heat exchanging efficiency is improved, and the whole energy consumption is controlled within the reasonable range.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an energy-saving control method and device for an air conditioner terminal in a data center computer room. Background technique [0002] Now, regardless of whether the computer room of the data center is in the cooling mode or the natural cooling mode, the water supply temperature at the end of the air conditioner is 7±1°C, and the air supply temperature is 23±1°C. Such as figure 1 as shown, figure 1 It is a schematic diagram of the air conditioning terminal control scheme of the data center in the prior art. Under normal circumstances, the actual load of the computer room is less than the design load, and it is in a low-load state, and the power consumption of each server changes as the system business changes, but the whole process from the temperature change of the computer room to the power adjustment of the electromechanical equipment is relatively slow Slow and lagg...

Problems solved by technology

Under normal circumstances, the actual load of the computer room is less than the design load, and it is in a low-load state, and the power consumption of each server changes as the system business changes, but the whole process from the temperature change of the computer room to the power adjustment of the electromechanical equipment is relatively slow Slow and lagging; the temperature of chilled water is low, and the heat transfer efficiency of precision air conditioners is low, which indirectly causes the electric cooling water system equipment to run at high power for a long time, and the energy consumption is relatively large
