2. Adwumayɛ parameter control akwan .

Abantenten a wɔato mu a ɛma onwini no yɛ adwuma no nya nkɛntɛnso tẽẽ wɔ ɔhyew a atwa yɛn ho ahyia, ɔhyew, mframa dodow, ne nea wɔde petepete so, na ɛhwehwɛ sɛ wɔyɛ nsakrae a ɛyɛ nnam denam nneɛma a edidi so yi so:

Esiane wɔn "indirect cooling + fluid protection" su nti, cooling towers a wɔato mu no yɛ ano aduru a wɔpɛ wɔ mmeae a edidi so yi:
