Core:Design and installation of commercial refrigeration and AC systems for on and offshore since 1987.Since 2012 also by utilizing the newest climate friendly technology with either CO2 or propane as refrigerant.Sustainable energy production and cooling systems has become a major field of interest and development both on and offshore, but most consumers still use old school direct electrical heating or a combusting source to produce for example heating for HVAC or hot tap water. Also, few are aware of the risk of using chemical refrigerants in their refrigeration and AC systems. Even the new so called "climate friendly" HFO refrigerants have contamination issues worth a second look #PFAS.Implementation of natural CO2 based heatpump systems will be adding at least 75% more value pr. spent kWh for consumers, also applicable for offshore LQs. This is possible by the use of Norwegian technology and products already in the market.By providing this environmentally friendly solutions we make the consumer's HVAC systems 75% more effective without using any dirty chemicals. Clean cooling and heating is a natural prerequisite for all applications installed by clients with a concern of their carbon footprint.This is my main field of work and interest within Winns as. #GoNatRefs #cleancoolingArne
