A straightforward framework for identifying key design parameters and determining their values for a site-built integrated collector storage solar water heater (ICSSWH) under uncertainty is developed. The framework is then used to evaluate the design for a ICSSWH, which uses locally available materials and can be assembled by builders without specialized training in solar system construction. I...

The shape of a solar collector is an important factor in solar-to-thermal energy conversion. Conical shape is one of the stationary and symmetric shapes that can be employed as a solar water heater. Flow rate of working fluid on the solar collector has an important effect on the efficiency of the collector. The present study is an experimentally investigated of the performance of the solar coni...

The biggest problem faced by the world these days is pure drinkable water, and in a few years, water will not be easily available, as it becoming brackish saline due to pollution. By using solar energy, still can produce which used for drinking, cooking, also industrial purposes. In this research, based on clean technology energy drive system that operated with an approximately negligible maint...

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...

use of fossil energy provides greenhouse gases emissions and therefore global warming phenomenon and the incidence of further consequences such as expanding deserts and blasting the dust storms in the middel east, including iran. taking advantage of renewable energy is the most appropriate solution to prevent greenhouse gas emissions. ahvaz region in the southwest of with a population of 133812...

One of the biggest obstacles to economic profitability of solar water heating systems is the investment cost. Retrofitting existing domestic hot water heaters when a new solar hot water system is installed can reduce both the installation and material costs. In this study, retrofitting existing water heaters for solar water heating systems in Swedish single-family houses was theoretically inves...

Solar Energy Applications Laboratory , Colorado State University . Fort Collins , CO 80523 Design of a vapor transport solar water heater using R-123 is optimized to maximize thermal performance and minimize life cycle cost. Optimal systems for one and twostory homes are identified in a parametric study of collector area, condenser heat transfer area, water storage tank volume and circulating r...

To develop indigenous alternative and renewable energy resources, long-term subsidy programs (1986–1991 and 2000–present) for solar water heaters have been enforced in Taiwan. By the end of 2010, the total installed area of solar collectors had exceeded 2 million square meters. However, over 98% of solar water heaters were used in residential systems for hot water production, with the areas of ...
