The chiller system in a building accounts for the main part of the building's total energy consumption, so it is critical to optimize the operation of chiller system for the purpose of saving energy. A chiller system generally consists of evaporation side and condensing side. The condensing side includes chillers, cooling water pumps and cooling towers, which form a subsystem of cooling water. It...
In this paper, Simulink model is built to simulate the chilled water system of a real building. The optimal chilled water flow rate and chilled water supply temperature are found out by traversing the constrained parameter values under different working conditions. The simple optimal control rules are developed based on the optimal solutions. Optimal control rules can reduce the total energy consumption...
