Simulation macro model for predicting mixing energy loss

The purpose of this study is to develop the technique that mixing energy loss is predicted at the time of the air conditioning system design by the simulation. If air conditioning load, which contains mixing energy loss, can be calculated easily at the time of air conditioning system design, we can design most suitable air conditioning system which mixing energy loss doesn't occur in. In this paper we would like to examine simulation macro model which  has following characteristics.

1. The room is divided into more than one zone in the vertical and horizontal direction.
2. Heat balance equations of the wall surface and the room air are calculated based on general idea of successive state transition.
3. Airflow between each zone is calculated by the calculation method of ventilation.
