Renewable energies and improving energy efficiency are the most important steps to achieve these energy policy goals. The use of CO2 heat pumps for hot water production has a great economic and environmental benefit regarding its energetic performance. A new model of a stratified storage tank is developed in our laboratory using FORTRAN developer studio and its simulation is conducted using TRNSYS simulation studio. %K Máquinas y Motores Térmicos %K CO2 heat pump %K TRNSYS numerical simulation %K Energetic efficiency %K 5312.05 Energía %~ GOEDOC, SUB GOETTINGEN
