Heat pump

1. Presentation

A heat pump is a device that uses a small amount of energy to move heat from one location to another. Not too difficult, right? Heat pumps are typically used to “pull heat out” of the air or ground to heat a home or office building, but they can be reversed to cool a building. Heat pumps also work extremely efficiently, because they simply transfer heat, rather than burn fuel to create it.

 
2. Market Analysis

The heat pump market is mainly driven by the high oil and energy prices, which have helped consumers embrace renewable technologies more than ever before. A greater awareness about the environmental impact of non-renewable technologies has also played a part in the market’s growth. Other key drivers behind increasing demand are the numerous incentives legislation supporting renewable technologies. There is also a desire among countries to rely less on oil imports.
The market is dominated by Sweden, which is the third largest market for HP in the world, behind the USA and Japan. It accounts for almost half of market revenues.
The other major markets in Europe are France and Germany. The Austrian and Swiss markets are approaching maturity. However, countries like Germany and France are experiencing high growth with HPs gaining wider acceptance due to greater awareness as well as legislation.

 
3. Commercial Potential for the Carnot engine

When comparing the performance of heat pumps, it is best to avoid the word "efficiency" which has a very specific thermodynamic definition. The term coefficient of performance (COP) is used to describe the ratio of useful heat movement to work input. The Carnot engine would have a very high COP in heating application.
