Abstract

The demand for energy-efficient cooling systems for use in telecommunications is rapidly increasing. After evaluating some of the alternatives to active cooling systems, the authors concentrated on the case of an outdoor cabinet and a cooling system based on a heat exchanger. To begin with, the airflow in a telecommunications outdoor enclosure was calculated with the help of a CFD simulation, which allowed a performance to be predicted. After that the monthly energy consumption of active and heat exchanger systems was evaluated for three places, one in northern, one in central and one in southern Italy. The study showed that energy savings about 50% are possible to achieve by replacing active cooling systems with systems based on heat exchangers. Other benefits are that the climate system availability will be higher due to decreased number of moving parts and the initial investment is also lower for a heat exchanger system. The most environmentally friendly kWh is a saved kWh. It is also important to remember that the heat exchanger solution does not require any use of CFCs.

一种具有成本效益和低环境影响的室外电子外壳气候控制方法

对用于电信的节能冷却系统的需求正在迅速增加。在评估了主动冷却系统的一些替代方案后，作者集中在室外机柜和基于热交换器的冷却系统的情况下。首先，在CFD模拟的帮助下，计算了电信室外外壳内的气流，从而可以预测其性能。然后对意大利北部、中部和南部三个地区的主动和热交换器系统的月能耗进行了评估。研究表明，用基于热交换器的系统取代主动冷却系统可以节省约50%的能源。其他好处是，由于减少了活动部件的数量，气候系统的可用性将更高，并且热交换器系统的初始投资也较低。最环保的千瓦时是节省千瓦时。同样重要的是要记住，热交换器解决方案不需要使用任何氟氯化碳。
