.Buildings.DHC.ETS.Combined.Subsystems.Chiller

Information

This is a model for a chiller system with constant speed evaporator and condenser pumps, and mixing valves modulated to maintain a minimum condenser inlet temperature (resp. maximum evaporator inlet temperature).

The system is controlled based on the logic described in Buildings.DHC.ETS.Combined.Controls.Chiller. The pump flow rate is considered proportional to the pump speed under the assumption of a constant flow resistance for both the condenser and the evaporator loops. This assumption is justified by the connection of the loops to the buffer tanks, and the additional assumption that the bypass branch of the mixing valves is balanced with the direct branch.
