Abstract
Impacts of the climate change on the space heating systems are discussed. We have used the latest global temperature data of the Global Climate Historical Network to demonstrate that the heating and cooling demand combined is decreasing in the world regions with boreal and moderate climate conditions almost everywhere. A simulation approach was developed to assess the impact of the climate change of the efficiency of a modern binary-cycle cogeneration power plant. Both statistical parameters of the air temperature and the thermal circuit of the power plant were modeled in details. It was found that even for a quite optimistic climate scenario the annual efficiency decrease may be as high as 1-2%. This means that careful consideration of the climate-related heating load dynamics is of key importance by implementation and renovation of the district heating systems.
Highlights
Decarbonisation of the domestic heating sector remains among the biggest challenges of the mitigation strategies in the moderate climate regions responsible for a significant part of the greenhouse emissions worldwide [1, 2]
We have used the latest data of the Global Climate Historical Network (GHCN) [8] to obtain a global picture
The overall space heating and cooling demand is increasing in the regions of the boreal and moderate climate zones
Summary
Decarbonisation of the domestic heating sector remains among the biggest challenges of the mitigation strategies in the moderate climate regions responsible for a significant part of the greenhouse emissions worldwide [1, 2]. The importance of this problem is quite obvious when remembering that the heating comprises more than a half of the final energy demand in these areas
