Development and implementation of HVAC-KBCD: A knowledge-based expert system for conceptual design of HVAC&R systems - Part 1: General framework

The general framework of a knowledge-based expert system (KBES) called HVAC-KBCD (knowledge-based conceptual design), capable of automatically synthesizing the complete set of possible HVAC&R systems, which can be analyzed using available building energy simulation programs such as DOE-2.1 E, was discussed. The design methodology, involving integrating a KBES, that can automate the synthesis of the various secondary and primary systems of building HVAC&R system, was described. General framework, structure, capabilities and inner working of the various elements of the KBES were demonstrated. The system configurations from the HVAC-KBCD can be made to comply with current energy standards, thereby ensuring compliance with energy codes.
