Nanofluids have great potential to improve the heat transfer properties of liquids, as demonstrated by recent studies. This paper presents a novel idea utilizing nanofluid. It analyzes performance HVAC (Heating Ventilation Air Conditioning) system using high-performance fluid (water-glycol nanofluid with nanoparticles Al2O3), in university campus Lecce, Italy. The work describes dynamic model b...

Solar heating technologies hold a significant potential to supplement or replace the fossil fuel-driven systems in residential and industrial applications. This paper presents techno-economic study aiming assess use of Unglazed Transpired Collectors (UTSC) coupled with an energy system assisted by Exhaust Air Heat Pump (EAHP) cold climates applied building cluster. The performance its component...

It is well known that the construction sector one of main sectors responsible for energy consumption in current global scenario. Thus, buildings’ software become essential tools achieving savings. Climate and its implications building performance are a critical threat. Hence, aim this study to evaluate climatic conditions urban suburban areas Rome, estimating incidence Urban Heat Island (UHI) p...

The implementation of renewable energy sources and heat pumps with natural refrigerants in the existing 3rd-generation district heating (DH) systems is a promising technology for conversion to 4th-generation DH system. This paper aims investigate this transition through case study system Croatia. Rijeka, which considered study, has an capacity 9.2 MW, was originally designed temperature regime ...
