The Grand Opening of the renovated Nikola Tesla Museum of Technology in Zagreb was recently held. Here, as part of the "Cheap-GSHPs" European project, Galletti and HiRef developed and installed an innovative CO2 and HFO geothermal heat pump. Thanks to a transcritical cycle it is possible to produce hot water at high temperature in an efficient and rational way, using refrigerants with a low environmental impact and a very low GWP value.
