Industry Overview

In the large-scale communication equipment room and core equipment room, the area is about 100-400m2, the cabinet density is high, and the heat generation is large. Generally, multiple direct-expansion air-cooled large-cabinet-type precision air conditioners with large cooling capacity are installed. A certain number of air outlets are arranged through the air duct. Generally, the direction of the cooling air flow of the cabinet is also considered. However, due to the placement of the equipment, there are socket flow in the channel of the cabinet, and high temperature alarms occur from time to time, which affects the normal operation of the cabinet. The date 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 communication equipment rooms.

Aolan Energy Saving Solution Advantages

In terms of ventilation and cooling in the data room, Aolan recommends the use of evaporative  air cooling system according to the actual situation.

Evaporative air cooling system solution: Under the conditions that can be connected to the water source, the evaporative air cooling system 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, which can realize the linkage control of multiple evaporative air coolers and multiple air conditioners 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.
