6 FAQs about [Hospital solar thermal system]

Can a solar thermal system supply hot water in a hospital?

Solar thermal system combined with gas boilers to supply hot water in a hospital. Solar fraction below design expectations (28% vs. 75%) due to huge thermal losses. Enhanced thermal insulation and extra collectors to reach 60% solar fraction. Refurbished system with hot water production cost estimated at 31–41 cent-€/kWh.

How much solar energy does a hospital use?

Adding the individual results of each hospital, 2,895,417 kWh/year will be generated for the minimum solar contribution (70%), 3,068,977 kWh/year for the 75% contribution and 3,239,578 kWh/year for the 80% solar factor which means an annual economic savings of 145,933.41 €, 153,503.46 € and 157,723.94 €, respectively.

Can solar DHW systems be used in New-built hospital buildings?

Future research can focus on developing reliable design methodologies for solar DHW systems in new-built hospital buildings. An integrated analysis approach will be implemented to identify those design parameters with major influence on the energy performance.

What are the components of a solar thermal system?

The installation is divided into (1) the solar thermal system, (2) the auxiliary system and (3) the hot water distribution network. The solar collector has a net caption area of 180.14 m2. It consists of three parallel-connected arrays of seven large-format collectors each. Each array is sub-divided into four parallel-connected subarrays.

Do cost-optimised solar systems reduce thermal losses?

The simulation results indicate that cost-optimised solutions generally expand the solar caption area by 43–57% and improve insulations to reduce thermal losses by 70%. Depending on carbon taxes, the cost of hot water production would be 31–41 cent-€/kWh, which represents a 15–45% reduction from the current costs.
