[Equest-users] Can Soper heat be recovered from DX condensers in eQuest?

[Phil Jordan]

Hi John,

I haven’t done this, but it does look like eQUEST has this capability.

If you search the DOE2 dictionary (e.g., https://doe2.com/Download/DOE-22/DOE22Vol2-Dictionary_48r.pdf) for “superheat”, you should see it appear a few times, with relevant information appearing in the COOL-WASTE-HEAT keyword and related keywords:

Be sure to read through the related keywords, though, as it appears to have different capability depending on system type; e.g., see WASTE-HEAT-USE:

To access these keywords within eQUEST, see the “Cap Curves/Waste Ht” tab within the “Heating” tab of an air-side HVAC system:

Best,

And can it be used to preheat either domestic hot water or space heat?

Thanks in advance.
