低温热源指品位相对较低的向热泵提供低温热能的热源,一般温度在80-200℃。低温热源包括空气、地表水、地下水、土壤、太阳热能、各种工业废热、地热、海洋温差等可再生能源。

也就是说我们希望高温热源温度尽可能高,同时低温热源温度尽可能低。
What that means is we want to run the hot reservoir as hot as possible and the cold reservoir as cold as possible.
低温热源的温度又是多少?
所要做的所有事情,就是把热量从高温热源输送到低温热源。
The whole thing is being powered by sending heat from the hot to the cold reservoir.
In principle, this value, this efficiency, can approach 1 as the low temperature approaches absolute zero.
这个值,效率,当低温热源的温度1,是据对零度时可以达到一。
What that means is we want to run the hot reservoir as hot as possible and the cold reservoir as cold as possible.
也就是说我们希望高温热源温度尽可能高,同时低温热源温度尽可能低,从原理上说。
The colder that cold reservoir is, the hotter that hot reservoir is, the better off we are.
低温热源温度越低,高温热源温度越高,效果就越好。
