Research of heat source analysis of communication engine-room and cold configuration

In order to cut down air-condition energy consumption in the communication room and reduce the heat island effect partially, through the use of CFD (computational fluid dynamics), we have a study on airflow characteristics in communication engine-room. On the basis of established mathematical and physical equation about airflow characteristics, we try to get the numerical solution, and analyze the speed field and the temperature field of the airflow comprehensively in air outlets and return-air intakes, around the communication equipments and in the cross-section of the engine room. Also we have an experimental test and verification analysis in the sample room. Experiments show that the numerical results are basically consistent with the measured values. From this we can see that the model is correct, and the result of numerical solution is credible. Finally, according to the result of numerical solution and the experiment test of the sample room, we can design the deployment program of the incoming (back) wind so as to optimize the operating environment of the equipments, reduce the cold waste and explore out the energy-saving potential in the engine room.
