Zoning cold supply energy saving system and method of data center air conditioner

Abstract

The invention relates to a zoning cold supply energy saving system and method of a data center air conditioner; the zoning cold supply energy saving system is characterized in that a machine room space is formed by an overhead floor, an indoor ceiling and a wall, wherein a common cold supply air conditioner and an accurate cold supply air conditioner are arranged in the machine room space; the machine room space comprises an accurate cold supply space and an external common refrigerating space; the accurate cold supply space is formed by a lower space of the overhead floor, an inner space of a machine cabinet, an air supply pipeline, an air return pipeline and the accurate cold supply air conditioner, and the external common refrigerating space is formed by an upper space of the overhead floor and the common air conditioner. The common air supply conditioner sends out cold air to the common refrigerating space; the same amount of cold air is returned; and the accurate air supply conditioner sends out cold air to the accurate refrigerating space. The zoning cold supply energy saving system completely changes the mode that for the traditional precise data center air conditioner, the total power of display cold of the air conditioner is calculated by the area of the whole machine room, thereby the required cold quantity is accurately calculated by using the area of the cold supply space; and therefore, under the condition that the energy consumption is greatly reduced, the installed capacity and the cost of the air conditioner are simultaneously reduced; and the requirement of equipment inside a cabinet for high-efficiency cold supply is also ensured.

Description

technical field [0001] The invention relates to an energy-saving system and method for air conditioning in a data center for sub-area cooling. Background technique [0002] Facing the role of data centers in social and economic development and the trend of rapid development of information society, various industries, especially telecommunications, mobile, finance and national-level large-scale data centers, have an urgent need for energy consumption and energy conservation. An important condition and foundation for building a conservation-minded society. [0003] The applicant applied for a patent earlier, the patent number is: 201110026991.7, and the name is: energy-saving and safe intelligent combined precise constant temperature and humidity cabinet. The general cooling method for the above-mentioned cabinets is through an air conditioner. However, the existing cooling method is generally air conditioner cooling, and the cold air is sent into the corresponding cabinets ...

AI Technical Summary

Problems solved by technology

In this cooling method, the space in the cabinet and the space in the computer room belong to the same cooling area. The large amount of cold and heat exchange will waste a lot of cooling energy, increase the energy consumption of air conditioning equipment, and fail to achieve the effect of energy saving.
