Design Method for the Heating/Cooling Coil in the AHU Based on Fuzzy Logic - Part One: Basic Structure and Characteristics Analysis
MetadataShow full item record
An AHU's energy performance is greatly influenced by its heating/cooling coil energy performance, which is also greatly influenced by the different kinds of control methodologies such as PID control and fuzzy logic control. The conventional actuating device consisting of motorized control valve and finned heat-exchanger is much more suitable to PID control instead of fuzzy control. To achieve a good control performance for heating or cooling coil by the fuzzy control method, an innovative finned heat-exchanger with adjustable area has been proposed in this paper. This paper introduces the energy and hydraulic characteristics analysis of the new heat-exchanger structure. Some practical implementation issues are also addressed.
