简单讲只是用看起来比较环保的方式取代传统的供热系统
How the Drammen heat pumps work
Water from the fjord at 8C is used to heat liquid ammonia at four times
atmospheric pressure (4 bar), till it boils at 2C and evaporates
从峡湾中取出的8°C 冰水,用来加热已经加压了4bar的液氨,直到高压液氨在2°C 时
沸腾并汽化
By increasing the pressure to 50 bar, the evaporated gas is heated to 120C
The gas is then used to heat the water in the heating system from 60C to 90C
(the water goes out of the plant at 90C and comes back in at 60C)
然后把压力增加到50bar ,蒸发的气体会被加热到120 °C , 这个高热气体就用来
把加热系统里60°C的水加热到90°C (这些水循环回来之后会变成60°C)
Once the heat has transferred to the water, the ammonia gas changes back into
a liquid state
The process begins again
后面就循环而已.....
发电你个懒觉头,就是一个新的供热系统
懒得去看他加压的能源是哪来的,要加压到50bar是需要相当大的能量
就只是跟旧系统比起来可以减少很多的温室气体排放而已....
又能扯到什么绿能发电真的是吼......
