這記者從一開始下標就故意亂下一通
實在懶得看這麼多英文:

簡單講只是用看起來比較環保的方式取代傳統的供熱系統
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
從峽灣中取出的8°C 冰水,用來加熱已經加壓了4bar的液氨,直到高壓液氨在2°C 時
沸騰並汽化
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)
然後把壓力增加到50bar ,蒸發的氣體會被加熱到120 °C , 這個高熱氣體就用來
把加熱系統裡60°C的水加熱到90°C (這些水循環回來之後會變成60°C)
Once the heat has transferred to the water, the ammonia gas changes back into
a liquid state
The process begins again
後面就循環而已.....
發電你個懶覺頭,就是一個新的供熱系統
懶得去看他加壓的能源是哪來的,要加壓到50bar是需要相當大的能量
就只是跟舊系統比起來可以減少很多的溫室氣體排放而已....
又能扯到什麼綠能發電真的是吼......
