In this paper, the experimental design and computer simulation model of a multi-effect humidification/dehumidification (MEH) solar desalination system has been presented. The pilot plant on MEH was designed, fabricated and tested at the Center for Energy Studies, Indian Institute of Technology Delhi, India. The heat collection part has been designed to provide continuously the hot water to the ...

Taking a barber shop in Dezhou City of Shandong Province as an example, this paper calculates the required heat by using 300 liters 40 °C hot water every day, introduces working principle and system characteristics electric heater solar heater, selects mainstream products market, use cost. The comparison shows that price is low, but annual cost high; high, low.

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 ...

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...

A commercial solar water heating system was evaluated for its effectiveness in decontaminating drinking water with a view to use in emergency situations. A total of 18 seeding experiments carried out over 6 months with 10(5) to 10(7)Escherichia coli/ml showed that the solar heater produced 125 l of bacteriologically safe water in 4 h when the ambient temperature was above 30 degrees C, with a h...

Now a day’s climate of growing energy needs and increasing environmental concern, alternatives to the use non -renewable polluting fossil fuels have be investigated. One such alternative is solar energy; water heating prime application energy. The problem faced by existing system periodic inspections, maintenance, time component may need repair or replacement also sufficient quantity hot not av...

Due to the reduction of fossil resources, replacement renewable energy sources such as solar has become mandatory. Solar does not contain pollution and widely available in all parts world, especially warm regions. Our country (IRAN) is geographically located a hot dry region, with more than 280 sunny days per year, one nonpower applications heating space water consumption building using thermal...

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...
