A novel Heat Pump configuration for very cold weather district heating

The analysis of thermodynamic cycles for Heat Pumps shows the possibility of developing Heat Pumps able to replace gas boilers in very high temperature heat networks.
The presentation shows the techno-economic and ecological interest of this type of development.

Description

The war in Ukraine has exposed the dependence of Europe on fossil fuels and created a new impetus to decarbonise the heating sector. Space heating and hot water heating represent roughly half of Europe’s final energy demand, with over 60 % coming from fossil fuels. The momentum for clean heat technologies has come, unleashing new opportunities for the District Heating (DH) sector. District Heating currently meets about 12 % of final energy use for space and water heating for households, service and industry sectors. The Heat Roadmap Europe project highlighted the significant potential of District Heating to cut imported fossil fuels by using renewable energy and waste heat sources: the sector could grow to meet 50 % of demands for space and water heating from the service and residential sectors.

There is a consensus on the use of heat pumps in the decarbonization process of Europe. District Heating plays an important role in greenhouse gas emissions. The replacement of gas boilers in district heating is a priority in this decarbonization process. Existing district heating networks have several thousand of kilometers of pipes installed. Some District Heating networks deliver hot water at very high temperatures (115 °C), such as in some Nordic countries or East of Europe (Poland). The analysis of thermodynamic cycles for Heat Pumps shows the possibility of developing Heat Pumps able to replace gas boilers in very high temperature heat networks. The presentation shows the techno-economic and ecological interest of this type of development.
