Automated design of branched duct networks of ventilating and air conditioning systems.

The paper presents a way of producing an algorithm for the automated construction of mathematical models of air conditioning and ventilating systems with branched air duct networks. The use of mathematical modelling in making aerodynamic calculations of air duct networks allows us to determine the actual value of air flow in network elements. It also permits us to achieve the required air flows effectively in the adjustment of a system. Such formalised methods of mathematical modelling, describing the properties of air conditioning and ventilating systems, means that their calculation can be completely automated. This is a precondition for the creation of a "cutting edge" program dealing with the complexities of automated design.
