  - Rynek Instalacyjny - Year 2006

  W pierwszej części artykułu omówiono zasady obliczania zapotrzebowania mocy cieplnej wg normy PN-B-03406, która obowiązuje od 1995 roku. Podano założenia obliczeniowe wg projektu normy PN-EN 12831, która jest normą europejską. Przedstawiono odpowiednie wzory na projektowe straty ciepła przestrzeni ogrzewanej, straty ciepła przez przestrzen nieogrzewaną, straty ciepła do gruntu oraz straty ciepła pomiędzy przestrzeniami ogrzewanymi...

  - Acta Energetica - Year 2013

  This article discusses the issues related to a power unit of a thermal power plant start-up with the use of a hydropower plant. Hydropower plant can supply and will enable start-up of auxiliary equipment in a power unit of a thermal power plant. Due to high capacity of auxiliary drives, start-up of auxiliaries in a thermal power plant after blackout (and boiler shutdown) is not possible from emergency energy sources in the power...

• Influence of external walls' thermal capacitance on indoor thermal comfort

  Publication

  • K. Arendt

  - Year 2013

  The doctoral thesis presents the results of numerical investigations on the influence of walls’ thermal capacitance on indoor thermal comfort. A proper set of thermal parameters of a building structure can considerably limit the heating / cooling demand, and passively increase the indoor thermal comfort. However the effect of building thermal capacitance on indoor conditions is complex and not always beneficial. Among a great number...

  - POLISH JOURNAL OF ENVIRONMENTAL STUDIES - Year 2014

  The article analyses the ORC system working with dry and wet low-boiling media which are most frequently used in installations of this type. Two types of cycles were examined, which were the cycle with heat regeneration for dry media: fc72, hfe7100, R227ea, R245fa, R423a and R600a, and the cycle without heat regeneration for wet media: R11, R12, R134a, R718 and 507a. The calculations were performed for the assumed required thermal...

• The Possibility to use a Nuclear Power Plant as a Source of Electrical Energy and Heat

  Publication

  • T. Minkiewicz
  • A. Reński

  - Acta Energetica - Year 2014

  In this article issues concernig the possibility of nuclear power plant (NPP) operation also as a source of heat, which means combined heat and power production, have been described. CHP work is possible and profitable only in those areas where high thermal power demand occurs, which means near city agglomerations such as Warsaw or the Tri-City. Two levels of thermal power delivered to the heating system have been considered. Preliminary...
