Modeling of an advanced integrated mechanical system for residencial applications

This paper describes the development and validation of a simulation model for Advanced Integrated Mechanical Systems (AIMS) destined for residential applications. AIMS are defined as mechanical systems that integrate the functions of residential space heating (optional cooling), heat recovery ventilation and hot water heating. Efficiency advancements of these systems are expected through the use of intelligent controls, high efficiency fans and motors,and the use of computer models to optimize the performance. The model was developed as a stand-alone application for testing and validation. The code of this stand-alone application was then  incorporated into the ESP-r computer program. Validation of the model against monitored house data with commercially available integrated heating and hot water units ("combos") shows good agreement. Since there are no commercially available AIMS systems at present,   further   testing   and   validation   will   be required.
