Renewable heating and cooling for a hospital

Southern European hospitals have high cooling and heating needs during the whole year. Combined district heating and cooling networks are, therefore, an interesting application. There are approximately 7,154 hospitals in Europe. Every hospital has considerable cooling needs and the excess heat from the cooling system can be captured and used in heat networks. Considering a conservative potential waste heat recovery tertiary buildings, up to 10 TWh year of heat could be supplied from this low-carbon source. The ReUseHeat project worked on an interesting application in hospitals in Madrid.

Thisted District Heating and Cooling

In 1984 the first geothermal plant has been established in Denmark, Thisted. In combination with two absorption heat pumps, excess heat from a waste incineration plant and a straw fired boiler it is part of a district heating network. This heat network delivers a total of 7 700 kW to 5 117 consumers in the area.

Gram Fjernvarme District Heating

Gram Fjernvarme is consumer owned and was until 2009 based on natural gas with a CHP unit and two boilers. In 2009 a solar field is established to provide solar thermal power to the heat network. The solar field is expanded in 2015 to a total area of 44 800 m2 of solar collectors providing 60% of the total heat demand. From 2016 onward excess heat from a neighbouring carpet factory is added to the district heating network.
