See the manual, DOE22Vol2-Dictionary, CIRCULATION-LOOP, TYPE = LAKE/WELL.
This type of loop will model your sea water heat sink.

Subject: [Equest-users] Sea-Water Cooled Chiller Modeling

Dear All,

Our project building is located in Istanbul/Turkey. Cooling will be provided by centralised two chillers. There is not a cooling tower. The project building location is very close the sea and this chillers will be fed by the sea-water condenser system.
There is a titanium plate type heat exchanger between sea-water and chiller condenser water. Sea water condenser flow and return temperatures 22C(71.6F) and 27C(80.6F).
Chiller condenser water flow and return temperatures 29C(84.2F) and 23C(73.4F). In addition, condenser total water flow rate is 340 kg/hr at 250 kPa.
How can sea-water condenser system be modeled in eQuest?

Thank you,
Best Regards.
