[Equest-users] Equest Cooling Towers

[David Eldridge]

If the chillers are running, the towers must also be running or else the condenser water would be getting very warm! As John A mentioned your files would help, or at least let us know which of the outputs makes you think the towers are not operating, or screen shots of the cooling tower dialog box.

One possible scenario is that you have some combination of high condenser water setpoint (causes towers to run less than if the water temperature is reset to a lower value) and efficient tower fans (kW/cell may be too low). The kW/cell in particular could be entered incorrectly, allowing your tower to run while not accumulating many kWh of end-use.

Hi, newbie eQuest user. I have modeled a fairly straight-forward loop that consists of multiple chillers and cooling towers. However, when I run the model, the chillers are running as they should but the cooling towers are not running at all, all year round. I tried running it with and without a tower water loop pump, to no avail. The fans are on VFDs. Any suggestions?
