Abstract
As traditional buildings are no longer capable to cope with the impact generated by the last generation microelectronic and information technologies, nowadays all residential or commercial buildings trends to be designed towards the goal of “intelligent building” (IB). An IB integrates complex heating, ventilation, and air-conditioning (HVAC) systems to create facility that is more comfortable and operationally efficient for its inhabitants. Obviously, there are intensive debates among scientists regarding the most adequate HVAC models in IBs development. In topic with these challenges, this paper introduces novel LabView-based models for store elements widely used complex HVAC systems implementation. These models have been developed by using an adequate mathematical background accurate describing complex hydraulic and energy-flow processes. Then originally conceived graphical software virtual instruments (VIs) have been designed to reproduce authentic models of store elements such as water tanks, gas containers, or other liquid reservoirs. The result is a powerful and versatile software toolkit well suitable to modeling and simulates complex physical phenomena in various types of HVAC systems. Even being well aware that in the last two decades a large amount of high quality research has been done worldwide to overcome same of the actually existing deficiencies and emptiness in HVAC systems modeling and simulation, the proposed original models are suitable offer a feasible solution for future developments and implementations in this research area.
