Note:
In this paper it is studied the techno-economic viability for the integration of a large scale solar cooling thermal plant in a District Heating and Cooling (DHC) network. This facility is foreseen to be located close to Barcelona in the framework of the Polycity project (Concerto Programme). Two configurations for the solar cooling plant are analysed. One of these configurations uses the solar plant to produce hot water at a relatively high temperature (90ºC) connected directly to the district
heating network and driving an absorption chiller. The second one produces hot water at a lower temperature to drive directly an adsorption chiller connected to the district cooling network. In each of these configurations different types of collectors, collector areas and the main operating parameters are be evaluated. The results obtained show that best system configuration to produce the required cooling consist of a selective FPC field of 1956 m2 using an adsorption chiller of 600 kW driven at a temperature of 65ºC. The total cost of the proposed solar cooling plant is around 100000 € and considering the potential subsidies for this innovative plant lead to interesting values of investment recovery.
