Chiller Condenser Heat Recovery

A chiller is usually thought of as a cooling machine, but it is equally a heat source: everything it removes from the cooled space, plus the electricity its compressor draws, comes out of the condenser as warm water, and on most sites that heat is dumped to a cooling tower and lost. Recovering it, instead of rejecting it, turns a chiller into a simultaneous cooling and heating machine, and where a site needs both at once it is one of the best recovery projects available. This lesson covers the opportunity, the timing constraint that governs it, and the storage that can loosen it.
