HVAC SYSTEM DESIGN AUTOMATION: ISSUES, METHODS, AND ULTIMATE LIMITS

We have developed software applications that design HVAC systems (that is, select, locate, and size components and their interconnections) given building descriptions, user preferences, and built-in rules. When this capability is combined with other key application characteristics (graphic interface, interactive recalculation, full integration, selfcontained reference data, strict retention of user modifications, and automatic parts selection), the result is a powerful assistant that greatly increases user productivity and design quality. Our application structure is a framework for iterative improvements in design and analysis algorithms and the addition of optimization techniques. We see this type of software ultimately replacing most design functions now performed by people.
