Development of HVAC system simulation tool for life cycle energy management- Part 2: development of component models for HVAC equipment

This paper describes the conversion of equipment characteristics into mathematical formulae, verification of the precision of said mathematical formula, and a concrete simulation tool. The main feature of this simulator is that operation of equipment is solved using temperature and flow, not calories. However, the characteristics of equipment are described using as simple a formula as possible. These formula are verified with actual values, and the simulator was confirmed to provide sufficient accuracy for energy management. When an object is connected to another object, calculation begins immediately without a main program. The detailed structure of objects and perspective of the simulation system are shown.
