</div>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p>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.<br>
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).
<br>
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.<br>
How can sea-water condenser system be modeled in eQuest? <o:p></o:p></p>
