The heat pump market has so far mainly focused on residential heat pumps for space heating and domestic hot water production. That means that industrial heat pumps are successfully integrated as low temperature heat recovery systems but rarely employed in processes with heat requirements above 100°C, due to very high investment costs, or non-existing technologies for the applications to be served.The project work will concentrate on the design of a high temperature heat pump for production of hot water (~105°C) from surplus heat. There were considered working fluids with accent on natural working fluids and after that it is calculated which working fluid should be chosen to achieve high energy efficiency. There is a wide range of application area for such systems. Successful application depends on the working principles of the heat pumps applied, the utilized working fluid and chosen components. All of those components and principles are briefly descriebed and the results indicate that mechanical compression heat pumps are most(suitable for heat recovery in those systems.
