Chilled water system economy cycle thro' cooling towers
Chilled water system economy cycle thro' cooling towers
(OP)
I have an application that has a large chilled water demand even in the middle of winter. It goes down to -5 deg C outside here regularly in winter and the outdoor temp is below 5 deg C for 15% of the year...
Can I use the cooling towers to provide cooling directly to the chilled waetr system via a heat exchanger...
Does 5degC outside mean I can get the cooling tower down to 5 degC?
Has anybody try this before, any literature on it anywhere on the web on how you would pie it and control it.
Thanks

RE: Chilled water system economy cycle thro' cooling towers
I was just reviewing an existing installation that used a Trane chiller with economizer mode for free cooling. The chiller uses convection of the refrigerant to cool the chilled water.
There should be details of a water-side economizer in the ASHRAE Handbooks.
Tower Tech towers have some descriptions of this application as well.
