Thermal Performance of a Double-pass Solar Air Heater

This study analyzes the thermal performance of solar thermal energy using double-pass absorber plate in Sanandaj, Iran. To this end, a mathematical model was encoded according to the energy and exergy balance equations and solved by MATLAB software. Given the environmental conditions and radiation intensity of a winter day in Sanandaj, the effects of external parameters such as radiation intens...

Dynamic System Testing Method and Artificial Neural Networks For Solar Water Heater Long-Term Performance Prediction

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...

Experimental Study on an Enhanced Performance Solar Water Heater

The paper presents preliminary results of an experimental study on solar water heater with full width and 75% twisted tapes as heat transfer enhancement device. The study shows that the thermal efficiency due the use of the twisted tape increases by 4.5-8%; higher for the 75% twisted tape. Keyword Solar water heater (collector), tube-in-fin, twisted tape, thermal efficiency, performance enhance...

Geyser Pump Solar Water Heater System Modeling Design Optimization

Solar thermal water heating systems reduce household energy bills by using the free solar radiation provided by the sun to heat water for residential needs. In order to eliminate the need for electricity to run a pump to drive the fluid circulation in these systems, fluid buoyancy effects can be employed to move the fluid from lower elevations to higher elevations. There are several operational...
