Pompe di calore./ Heat pumps.

Author(s) : HALOZAN H.

Summary

The old aim of governments was to supply their country with sufficient low-cost energy to keep the economy growing. But in the meantime we have some more problems: the one problem is that energy becomes more and more expensive, the second problem is climate change, and all industrialised countries, which have signed or not yet signed the Kyoto Agreement, have to reduce their greenhouse gas emissions, mainly CO2 from burning fossil fuels. Heat pumps offer the possibility of reducing energy consumption significantly, mainly in the building sector, but also in industry. The second law of thermodynamics shows the advantages: while a condensing boiler can reach a primary energy ratio of at best 105% (i.e. the boiler efficiency; the theoretical maximum would be 110%, based on the lower calorific value), heat pumps achieve 200% and more.
