Using high-temperature seawater heat pump for pool heating and domestic hot water preparation in a special hospital

Heat pumps are recognized as energy efficient and environmentally friendly technologies for cooling and heating. The objective of this paper is to identify the economic and environmental potential of seawater heat pump installed in a specialized hospital on the Mediterranean coast. A seawater heat pump is operating in the heating mode throughout the whole year and it is used for pool heating and domestic hot water production. Energy demand was studied for a whole year, and the economic benefits, as well as primary energy savings and CO₂ emissions reduction, were analysed. The analysis showed that the seawater heat pump would lead to 25% lower costs, 52% primary energy savings and 63% of CO₂ emission reduction in comparison to fuel oil boiler.
