Abstract

This research focuses on the evaluation of thermal energy efficiency in a building including thermal cascading systems such cogeneration, solar-thermal, and PY systems, combined with final energy consumption for space heating and cooling, dehumidifier, and a water heater. The thermal energy efficiency of the whole system varies depending on not only calorific balances but also on the temperature of heat conveying media and its flow-rate to each consumption unit. Based on the concept the simulation tools, the major development work involves the modeling of cogeneration units. As the first development phase, a sample system consisting of one unit of each form of equipment has been completed adopting the "forward method." This paper describes the overview of the method by showing some results for a sample case study.
