This work aims to design and dynamically simulate a polygeneration system that integrates solar-assisted desiccant cooling for residential applications as an alternative vapor compression systems. The overall plant layout supplies electricity, space heating cooling, domestic hot water, freshwater single-family townhouse located in the city of Almería Spain. leading technologies used are photovo...

Solar thermal collector system is a widely used solution involving renewable energy source to cover the demand for domestic hot water production. At Italian level, UNI TS 11300 provides calculation methodology based on two approaches: asset rating, which easy be applied but approximated results, and tailored more reliable requires several detailed information. In this context, present work prop...

In this communication, a study has been carried out to evaluate the life cycle cost analysis and carbon credit earned by hybrid PV/T solar water heater. The study has been based on thermal, electrical and exergy output of water heater. The solar water heater is installed at Solar Energy Park, IIT Delhi. The annual energy and exergy gain have been evaluated by considering four types of weather c...

Although the European reports highlight an increase in community-acquired Legionnaires' disease cases, the risk of Legionella spp. in private houses is underestimated. In Pisa (Italy) we performed a three-year survey on Legionella presence in 121 buildings with an independent hot water production (IB); 64 buildings with a central hot water production (CB); and 35 buildings with a solar thermal ...

One challenge in today’s district heating systems is the relatively high distribution heat loss. Lowering temperatures one way to reduce operational costs resulting from losses, while changing system steel pipes plastic and concept can investment costs. The result that overall life cycle cost of reduced, leading improved competitiveness versus individual options. main aim this study was determi...
