A coupled cooling system for an electronic information machine room

Abstract

The invention discloses an electronic information machine room coupling-type cooling system. The electronic information machine room coupling-type cooling system comprises a water chilling machine set, an open-type cooling tower, a plate-type heat exchanger and a dry-type cooler. The water chilling machine set and the plate-type heat exchanger are connected in parallel, and the water chilling machine set and a heat releasing end of the plate-type heat exchanger are respectively communicated with a pipeline of the electronic information machine room coupling-type cooling system. The water chilling machine set comprises a condenser and an evaporator, wherein the condenser and the evaporator conduct mutual heat change, the evaporator is communicated with a pipeline of the electronic information machine room coupling-type cooling system, and the condenser is communicated with a pipeline of the open-type cooling tower. A heat absorbing end of the plate-type heat exchanger is respectively communicated with a pipeline of the open-type cooling tower and a pipeline of the dry-type cooler. According to the electronic information machine room coupling-type cooling system, the problem that in winter, a natural cold source is used for cooling, so that the open-type cooling tower is halted or cannot run normally due to freeze can be solved, the problems that the electronic information machine room coupling-type cooling system is halted or cannot run normally, so that a machine room rises in temperature and is over hot is avoided, and the natural cold source is effectively used for conducting cooling on the machine room.

Description

technical field [0001] The invention relates to a cooling technology for an electronic information machine room, in particular to a coupled cooling system for an electronic information machine room suitable for year-round use. Background technique [0002] With the rapid development of industries such as global communications, the Internet, the Internet of Things, e-commerce, and cloud computing industries, both communications operators, governments, and enterprises need to build a large number of electronic information centers, such as IDC, EDC, and other data centers , The common feature of these computer rooms is huge energy consumption. With the improvement of the utilization rate of the electronic information room, the overall energy consumption of the electronic information room, especially the energy consumption of the air conditioner, has been increasing in recent years, especially for large and super large data centers. In order to make full use of natural cooling s...

AI Technical Summary

Problems solved by technology

[0003] (1) In winter, the open cooling tower freezes, which causes the chiller used to cool the computer room to fail to open normally, the temperature of the computer room rises, and the server overheats, which brings potential safety hazards. There are concerns

[0004] (2) The open cooling tower freezes in winter, causing the energy-saving technology of the open cooling tower to cooperate with the plate heat exchanger to fail to operate normally, which actually reduces the utilization time of the natural cold source and cannot achieve the expected energy-saving effect

[0005] (3) In order to ensure the use of open cooling towers in winter, measures such as electric heat tracing are generally adopted, which increases energy consumption. At the same time, there is still the possibility of freezing in some places where electric heat tracing is not convenient to arrange, resulting in the cooling tower stopping or failing. Normal operation, there are potential safety hazards in the electronic information room

[0006] (4) The cooling tower has water consumption phenomena such as evaporation, overflow, and sewage discharge, and requires a large amount of water replenishment. Compared with the air-cooled air-conditioning method, there is a disadvantage of excessive water resource consumption, and the larger the scale, the greater the water consumption
