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.

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...

This paper presents the study of fluid flow and heat transfer in a plain rectangular duct of a solar air heater by using Computational Fluid Dynamics (CFD). The effect of Reynolds number on heat transfer coefficient and friction factor was investigated. A commercial finite volume package ANSYS FLUENT 12.1 is used to analyze and visualize the nature of the flow across the duct of a solar air hea...

Abstract—This paper deals with the analytical investigation of thermal and thermohydraulic performance of double flow solar air heaters with corrugated and flat plate absorber. A mathematical model of double flow solar air heater has been presented, and a computer program in C++ language is developed to estimate the outlet temperature of air for the evaluation of thermal and thermohydraulic eff...

––Based on technology and economy, a design of explosion-proof heater of bunched pipeline is mentioned in this paper to solute the problems of the present heater which is used to heat crude oil in winter. The structure and working principle of this new heater are introduced. And the function of the new heater’s swirl plate is described, before the heater power of the new heater is analyzed. The...

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...
