Evaporative Pad Fresh Air in Small Aggregation Equipment Room of Communication Base Station
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 and small aggregation equipment rooms, Aolan recommends the use of evaporative pad fresh air cooling system solutions according to the actual situation.
Solution of evaporative pad fresh air cooling system: Under the condition that the water source can be connected, the evaporative pad fresh air system of Aolan data computer room can be used. Make full use of the dry air energy with low wet bulb temperature in winter and transitional seasons, the outdoor fresh air is sent into the room after being filtered and purified, evaporative cooling, absorbs the heat of the indoor IT equipment into high-temperature air, and then is discharged outdoors through the forced exhaust fan. The system is equipped with a special intelligent control system for the Aolan base station, which can realize the linkage control of the evaporative air cooler and the air conditioner of the computer room, so as to ensure the normal operation of the computer room under the proper temperature and humidity conditions. Save energy and reduce consumption, reduce operation and maintenance costs, and reduce the PUE of the computer room to below 1.10.
Project Introduction (1)
This project is an evaporative pad fresh air energy-saving renovation system for base stations and small computer rooms of China Telecom in various cities in Guangxi. The evaporative pad fresh air system is operated in spring, 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 2012. It can run for more than 3,000 hours a year, and the annual power saving rate can reach 30%.
Project Introduction (2)
This project is an evaporative pad fresh air energy-saving renovation system for a convergence machine room in Heilongjiang, China Unicom. It adopts Aolan special evaporative air cooler and base station special intelligent control system. The evaporative cooling water pad fresh air system is operated in spring, autumn and winter, and the original compressor air conditioning system is operated in high temperature and high humidity weather such as summer. The project was put into use in 2015. It can run for more than 7,500 hours a year, and the annual power saving rate can reach 75%.
