Hello,


I have a question about desuperheaters. I am doing a remodel and had to move my condenser to a new location. While I was moving it, I decided to install a desuperheater. The DSH is actual the water coil from a previous 5ton geothermal unit, so it is fairly large and should give good thermal transfer. The original plan was just to use it to heat domestic hot water. However, I do have another source of fresh cold water (well and spring both), and thought that once the hot water needs are met, I could switch over to open loop well water and basically have a groundsource ac running. The only caveat is that I would have an extra condenser (the outside air coil) in series after it. I will kill the outside fan if running in groundsource mode.

Assuming I flow enough water through the coil to condense all the ***** back to liquid inside the water coil, will that cause problems trying to flow through the existing air condenser? The outside coil is a carrier microchannel.

Any comments/suggestions would be greatly appreciated.

System details:
Copeland 5ton Scroll
Packless water coil from 5T geothermal heat pump.
Carrier 5ton outside Microchannel Air condenser
Air handler is a 5T Goodman with variable speed.


Thanks in Advance.
