Integrating Low-temperature Heating Systems into Energy Efficient Buildings☆

摘要: Abstract Energy requirements for space heating and domestic hot water supplies in the Swedish building sector are responsible almost 60% of total energy used. To decrease this enormous figure, saving measures required, as well opportunities to use low-temperature systems increase sustainability. The present paper studies systems, including heat production units (district or pumps) emitting room. aim was find an answer question whether not efficient sustainable compared with conventional systems. question, we considered different efficiency aspects related exergy. analysis showed that more environmentally friendly than This attributed pumps district lower temperature emitters using a greater share renewable resources less auxiliary fuels. report discusses pros cons types emitters.
