Control for HVAC Chilled Water System

12890,12891,11835

Based on the principle of conservation of energy, a dynamic heat transfer model is developed. a two-dimensional fuzzy controller is designed to control chilled water flow and chilled water inlet temperature after analyzing the model, so as to achieve the purpose of adjusting the supply air temperature. To verify the feasibility of the proposed method, simulation experiments is made by using MATLAB FIS editor. The results of simulation show that the designed controller can effectively adjust the cooling coil supply air temperature with a small steady-state error, and have the ability of anti-interference.
