Going through the worst energy crisis in decades, society is struggling to break free from its dependance on gas, coal and oil and find alternative, reliable heat sources. Heat pumps represent an important piece in the new energy puzzle, and in this presentation A heat pump is basically a refrigerator in reverse. It moves heat from a cold medium (the heat source) to a hotter medium, for example by taking heat from 10 °C ground water and using it to heat a building.

Heat exchangers are central components in heat pumps, largely determining their overall efficiency. Besides delivering maximum heat transfer, a heat exchanger in a heat pump must also be capable of operating with two phases (gas and liquid), large tem ...
