Mathematical Modeling of Basic Parts of Heating Systems with Alternative Power Sources

摘要

In connection with the development and the growing integration of renewable energy sources into energy systems, it is still important to work on options for optimization of energy processes. The issue of energy systems for low energy buildings is currently the basic trend in reducing energy demands of buildings and is in accordance with the requirements of sustainable development. There are defined the conditions for correct approach in the design of energy systems with heat pumps and solar systems and there are presented selected results from the modeling of operational states of this sources.
