Cold water system capable of reducing operation time of main frame

Abstract

The invention discloses a cold water system capable of reducing operation time of a main frame. The cold water system comprises a mechanical refrigeration system and a natural cold source system, wherein the mechanical refrigeration system comprises a cold source device, a data machine room used precise air conditioner, a cooling tower, a first circulating water pump and a cooling water pump, themechanical refrigeration system provides first chilled water with the temperature ranging from 5 DEG C to 23 DEG C through the cold source device, the first chilled water is conveyed to a low-temperature cold water coil pipe in the data machine room used precise air conditioner through a chilled water pipeline, the first circulating water pump supplies power to the first chilled water, the naturalcold source system comprises a heat exchange device, the data machine room used precise air conditioner, a cooling tower, a second circulating water pump and a cooling water pump, wherein the naturalcold source system provides cooling water through the cooling tower, the heat exchange device is used for converting the cooling water into second chilled water with the temperature ranging from 5 DEG C to 23 DEG C, the second chilled water is conveyed to a high-temperature cold water coil pipe in the data machine room used precise air conditioner through the chilled water pipeline, and the second circulating water pump is used for providing power for the second chilled water.

Description

technical field [0001] The invention relates to the field of heating, ventilating and air-conditioning, in particular to a cold water system which reduces the running time of a main engine. Background technique [0002] At present, a large amount of heat is generated during the operation of a large data center. In order to support the normal operation of the data center, it is necessary to discharge the waste heat in the computer room, which requires a refrigeration and air conditioning system to achieve. The process of cooling and heat removal often requires a large amount of energy consumption such as electricity and gas, which accounts for a large proportion and limits the profitability of large data centers. [0003] The usual ways to discharge waste heat are mainly divided into three ways: air cooling, water cooling, and liquid cooling, among which water cooling is usually used in large data centers. One of the important ways to reduce data center energy consumption is...

Problems solved by technology

This connection method increases the natural cooling and pre-cooling hours to a certain extent, but this method still has certain defects in resistance control and pre-cooling potential

In addition, there is another method of using heat pipes to dissipate heat from the CPU in the data cabinet. This method can provide a large number of hours of natural cooling, but this method brings great inconvenience to the layout of the computer room and cabinets. In actual projects, it is very use less
