The performance of an air-source heat pump water-heater (ASHPWH) system manufactured by Kronoterm was benchmarked in this study for the application dairy farming Ireland. COP calculated to be 2.27 under normal operating conditions. device able supply water at 80 °C, however a full tank temperature not achieved or deemed necessary application. Litres per kWh used as metric and usable unit energy...

<p class="abstrak">Solar energy is one of the most impactful renewable sources and has great potential compared to other sources. The use solar can be maximized by using panel technology collectors. One example a water heater. Polycarbonate good material applied heaters because it mechanical properties corrosion resistant. This study aims analyze performance polycarbonate heater with tric...

in this research a flat plate solar air collector was investigated under direct solar radiation consisted of a slatted glass cover, perforated absorber aluminum sheets (porosity 0.0177, 0.0314 and absorber thickness of 2.5 mm). the effect of porosity on absorber efficiency of collector was evaluated. six levels of air mass flow rates (0.0056 to 0.0385 kg m-2 s-1) were adopted.average solar ener...

Fish as a source of animal protein is fishery commodity that prone to quality deterioration and spoilage after the fish caught, so it needs fast, precise correct handling keep its in hands consumers. There for necessary have process extends durability through drying. One drying alternative use Solar Air Heater with an Ultra Violet (UV) Dryer house by making building made transparent material fu...

The performance of a solar hot water thermosyphon system was tested with the dynamic system method according to Standard ISO/CD/9459.5. The system is of closed circuit type and consists of two flat plate collectors with total aperture area of 2.74 m and of a 170 liters hot water storage tank. The system was modeled according to the procedures outlined in the standard with the weather conditions...

Effects of insertion of coiled wire in juxtaposition with twisted tapes on heat transfer rate and solar radiation without disturbing the flow inside the riser tubes in a solar flat plate collector is experimentally reconnoitered in this present work. The wire coil used as a turbulator is placed inside the riser tube while the twisted tape is inserted into the wire coil to create a continuous sw...
