Improved structure of distributed air-conditioning system for data centre

Abstract

The invention discloses an improved structure of a distributed air-conditioning system for a data centre, wherein the improved structure comprises a plurality of precise air-conditioning heat exchangers and a plurality of cabinet top air-conditioning evaporators; a chilled water condensing end 1 of each precise air-conditioning heat exchanger exchanges heat with a heat exchanging evaporator of anoutdoor refrigerating system; the improved structure further comprises a refrigerant circulation system; the plurality of cabinet top air-conditioning evaporators are connected in parallel in the refrigerant circulation system; an inlet end of each cabinet top air-conditioning evaporator is provided with a valve; a condensing end 2 of the refrigerant circulation system exchanges heat with an evaporating end of an intermediate heat exchanger; and a chilled water condensing end 3 of the intermediate heat exchanger exchanges heat with the heat exchanging evaporator of the outdoor refrigerating system. By means of the improved structure disclosed by the invention, problems of local overheating and overhigh energy consumption of cabinets in a machine room are solved better, and the distributedair-conditioning system is better optimized and has a simpler structure and reduced invested cost.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to an air-conditioning system used in an information data equipment room. Background technique [0002] Data center, that is, information and data equipment room, with the continuous improvement of people's technical living standards, the application of information technology and networks has increasingly penetrated into all aspects of people's production and life, and they are also revolutionizing people's lives. At the same time, the number and scale of data and information storage and exchange devices are also increasing. There are a large number of IT equipment in the data and information storage and exchange center, which has a certain power and a high heat generation rate; the normal operation of the equipment requires a good temperature environment. At present, it is common for precision air conditioners to implement downward air supply in computer rooms. This technology solves ...
