Industry Overview

Generally, 1-2 computer room air conditioners or ordinary split air conditioners are installed in communication base stations and small aggregation equipment rooms. The air conditioners are placed directly on the side wall of the room, regardless of the direction of the cooling airflow of the cabinets. There is a nest flow in the cabinet channel, and high temperature alarms. Such phenomena occur from time to time, affecting the normal operation of the cabinet. The computer room is airtight, and the compressor operates uninterruptedly throughout the year for refrigeration, with high failure rate, large power consumption, and high operation and maintenance costs. Making full use of natural cold sources, reducing or canceling the running time of mechanical compressor air conditioners, reducing energy consumption, lowering PUE value, and reducing maintenance costs for air conditioner failures have become the main direction of energy-saving renovation of base stations and small computer rooms.

Aolan Energy Saving Solution Advantages

In terms of ventilation and cooling of communication base stations, Aolan recommends the use of intelligent fresh air system according to the actual situation of the base station.

Intelligent fresh air system solution: In the case of remote base stations and small aggregation equipment rooms far away from towns, where there are no resident personnel on duty, or no access to water sources, Aolan Reeled Fresh air unit can be used. The outdoor fresh air of suitable temperature is directly sent into the room after being filtered and purified, absorbs the heat of the indoor IT equipment to become high temperature air, and is discharged to the outside through the forced exhaust fan. Ensure that the cabinet operates normally under suitable temperature and humidity conditions. The PUE of the computer room can be reduced to less than 1.15; the equipment is equipped with a large-area filter screen on the reel, intelligent detection, intelligent rotation and replacement, and the annual maintenance is as low as 1 time, with less maintenance workload and low maintenance cost. Because of the large use of low-temperature outdoor cold sources, the operation time of the air conditioner in the computer room is reduced, energy consumption is reduced, and failures are reduced.

Project Introduction (1)

This project is an intelligent fresh air energy-saving system for a base station of China Unicom in Fujian, using 1 Aolan reeled fresh air unit and 1 exhaust fan. The intelligent fresh air system is operated in early spring, late autumn and winter, and the original compressor air-conditioning system is operated in summer and other high-temperature and high-humidity weather. The project was put into use in 2018. It can run for more than 3,000 hours a year, and the annual power saving rate can reach 28%.

Project Introduction (2)

This project is an intelligent fresh air energy-saving renovation system for a base station of China Unicom Inner Mongolia. It adopts an Aolan Reeled fresh air unit and an exhaust fan. The intelligent fresh air system is operated in spring, autumn and winter, and the original compressor is operated in high temperature and high humidity weather such as summer. Air conditioning system, the project will be put into use in 2020. It can run for more than 6,500 hours a year, and the annual power saving rate can reach 56%.
