Explanation: batería de intercambiadores de calor is "bank" and not battery. Can`'t help with the rest. Sorry. I found several web pages the other day using this term in these contexts. I didn't bookmark them though. You may want to try searching for "bank" and "battery" in the same texts as your other terms and see what you get.
