Description

technical field [0001] The invention relates to an air circulation device for a communication machine room, specifically an energy-saving device for external circulation heat exchange in a communication machine room. Background technique [0002] With the progress of the society and the rapid development of the communication network business, the communication network sites and IDC communication rooms in various places have been "scattered", and in order to improve the quality of communication, there is a trend of encryption and expansion, and the energy consumption of network equipment operated at the same time also showed a straight-line upward trend. Therefore, how to save energy and reduce consumption under the premise of ensuring network quality, reduce operators' network operation and maintenance costs, and realize "low-cost, high-efficiency" operation is the biggest problem facing every operator. [0003] At present, the existing communication equipment room adopts a...

Problems solved by technology

[0005] One is low efficiency: Due to the moisture-proof and dust-proof requirements of the communication room, the existing communication ventilation equipment generally adopts two-stage filtration and absorption, and two-stage filtration is used. Although the dust-proof and moisture-proof problems are solved to a certain extent, but It also brought about a fundamental problem, that is, after being blocked by the two-stage filter, the actual amount of cold air introduced by the ventilation equipment in the computer room is small, the heat carried by the fresh air is seriously insufficient, and the use effect is not obvious

Second, the maintenance workload is heavy: the change of air quality, ambient temperature and temperature difference is the key period for adjusting the temperature of the computer room. In the three seasons of spring, autumn and winter in the area north of the Yangtze River and Huaihe River in my country, the phenomenon of blowing sand, floating dust and floating flocs is common.

During the operation of the ventilation motor in the computer room, the blowing sand, floating dust, and floating lint often cause the phenomenon of "dirty blockage" in the short-term operation of the two-stage filter

According to the actual maintenance experience, the ventilation and energy-saving equipment in the general computer room will be completely dirty and blocked after running for about half a month, and the two-stage filter needs to be replaced once. There are hundreds of sites in a city, and the maintenance workload can be imagined

The third is high operating costs: replacing the two-stage filter screen once every half a month brings at least two cost problems: a large number of filter screen spare parts need to be configured, which increases the cost very high; a large amount of maintenance manpower, material resources, and transportation tools need to be invested increase operating costs

The fourth is that it is actually in a state of abandonment: in the current situation where the network maintenance funds are limited and the maintenance personnel and transportation equipment are relatively tight, it is impossible to replace the two-stage filter once every half a month

This has led our communication companies to invest a lot of money in the construction of thousands of ventilation equipment in the communication room, but the filter screen cannot be replaced in time. What kind of "criminal" waste is it to consume electricity

Fifth, there is a potential fire accident: when the operating temperature of the external environment is set, even if the filter screen of the ventilation equipment in the communication room is in a "dirty and blocked" state, the ventilation motor will continue to run

We know that the ventilation motor itself is cooled by circulating cold air. In this state, there is basically no cold air flowing through the motor, which will cause the coil of the ventilation motor to continue to heat up for a long time, which is prone to insulation aging and damage, and even causes short-circuit fire accidents. There are obvious hidden dangers of fire safety accidents
