You can use heat exchangers between outlet and inlet air to mitigate a good portion of the energy cost I believe.

- stkdump 5y agoIf the outflow is not compressed, you can transfer at most half of the heat and that is under perfect conditions.
- lhopki01 5y agoThat's not quite right. If the airflows are in opposite directions then you can transfer more heat. Since as the hot air cools it encounters progressively colder air ensuring there is always a temperature gradient to transfer heat. These systems are about 60%-90% efficient at transfering heat.
