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...

Energi matahari sebagai sumber energi terbarukan dapat dimanfaatkan menjadi energy termal untuk proses pengeringan. Pengeringan menggunakan instalasi solar water heater, penukar panas, dan ruang pengering bahan. Penelitian ini bertujuan mengetahui data temperatur air keluar dari heater menghitung efisiensi penyerapan panas pada kolektor heater. dilakukan dengan mengukur temperatur, intensitas c...

To minimize environmental impact and CO2 production associated with air-conditioning system operation, it is reasonable to evaluate the prospects of a clean energy source. Solar energy can drive an absorption chiller in order to satisfy the cooling needs of buildings. The objective of this work is to build a simulation environment that can evaluate accurately the energy consumption of an air co...

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 ...

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...

This article presents the results of experimental studies main thermal characteristics a solar collector, heated air duct an indirect type drying plant for agricultural products. The temperature measurement at lower, middle and upper parts entrance output heater different radiation intensities during day in periods month city Tashkent are given. calculation volume flow through heater, specific ...

In this investigation, the effect of replacing conventional solar absorber with a new on thermal performance double-pass air heater has been studied experimentally and numerically. Three configurations have introduced, first configuration is double pass flat plate (DPSAHWFP) for aim comparison, second tubular that includes set tubes which are fitted perpendicularly to direction airflow (DPSAHWT...

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...
