US Patent:

20060010893, Jan 19, 2006

Filed:

Jul 13, 2004

Appl. No.:

10/890585

Inventors:

Daniel Dominguez - El Paso TX, US

International Classification:

F25D 17/02

US Classification:

062201000

Abstract:

A method () and a low capacity controller () enable a chiller system () to operate below a minimum allowable capacity. The chiller system () includes a chiller () and a chiller fluid loop (), having a supply line () for conveying a chiller fluid () from the chiller () and a return line () for returning the chiller fluid () to the chiller (). A capacity demand for the chiller () is determined. When the capacity demand is less than a minimum allowable capacity of the chiller (), the chiller fluid () is routed from the return line () to a heat exchanger () of the low capacity controller () where the chiller fluid () is warmed and returned to the return line (). The warmed chiller fluid () establishes a false capacity demand, detectable at the chiller (), that is at least the minimum allowable capacity.
