Information

This is a partial model for a primary-only chiller plant with two parallel chillers. It has two headed variable speed chilled water pumps, two headed constant speed condenser water pumps, and two cooling tower units. Detailed description can be found in Buildings.Examples.ChillerPlant.Guideline36.ClosedLoop.
