Neither. There are more obstacles that physics and DOE rating.
None of the big guys wants to build one as they dont think the
market is big enough or lucrative enough. AAON is prototyping a
midsize (3-5 ton) version, and Lennox is trial marketing a system
with limited reheat. <br>
I think it is a great idea. But I dont build or sell systems.<br>
<br>
There are many commericial 5-20 ton systems that do this. And many
other ways to acheive the same result.<br>
