Heat pumps versus combined heat and power production as CO2 reduction measures in Finland

摘要: Abstract Heat pumps have rapidly gained popularity in the Nordic area, as they are marketed to provide considerable monetary savings and CO 2 emission reductions. installed even buildings heated by CHP (combined heat power production). In this paper we calculate factors of DH (district heating) from GSHP (ground source pumps) Finland, based on hourly data at present various future scenarios. LCA (life cycle assessment) analyses, usually only annual averages used. We show that including seasonal variation can result very different factors. Since during warm seasons, electricity production is significantly less carbon-intensive than cold seasons. find current factor consumption change 70–100 g/kWh. it 0…300 g/kWh, depending intensity production. The similar would develop 200 g/kWh 50…200 g/kWh. As long has or coal condensing significant interconnected network, lower emissions GSHP. recommend using CLCA (consequential LCA) methodology inclusion heating option comparisons.
