I seem to be talking about heat recovery almost daily so I had to do a follow up podcast with Multistack to add to the modular chiller podcast (Episode #24).  I had Ed Watson define heat recovery and go through the 3 heat recovery options they have.  We talked about the water to water heat recovery, 4-pipe air source heat recovery and their VME 6-pipe heat recovery system.  We also talked about water temperature which always seems to catch engineers off guard so it was essential we went through it.  If you want to see pictures of these systems, go to Multistack.com or email me and I'll walk you through them.  [email protected] or 949-698-3014
