I don’t often get to blow my own trumpet here, but the beginning of a new year is a good time for self-evaluation, and good news is always worth sharing. Ten years ago we commissioned a large river source heat pump system in Norway, recognized at the time as the largest and most efficient high temperature natural refrigerant heat pump in the world. The project won several awards, including the ASHRAE Comfort Cooling Award for Project Excellence, in recognition of the technical, commercial and financial successes it delivered for the district heating company who operate it. © 2021 Amer.
