一般使用绝热管道进行远距离传送热能是不太容易的事,因为在传送过程中热量损失严重。最近美国正在试验一种在室温下用气体混合物传送热能的新方法。
Generally, it is not easy to use heat-insulated pipes to transmit heat energy over long distances because of the heavy heat loss during the transmission. Recently the United States is experimenting with a new method of delivering thermal energy with a gas mixture at room temperature.
