In this paper we present a prototype for a new type of solar thermal collector designed for architectural integration. In this proposal, the conventional geometry of a flat solar thermal collector is changed to a curved geometry, to improve its visual impact when mounted on a building facade or roof. The mathematical equations for the beam and diffuse solar radiation received by a collector wit...

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...

ABSTRACT The use of a thermoelectric generator (TEG) in generating useful power from solar thermal energy is demonstrated. This device represents a portable and autonomous power generation system operating from solar power, capable of powering micro/nano systems. The TEG was integrated with a micro solar thermal collector plate to enhance the thermal radiation absorption capacity of the hot sid...

In order to effectually improve the performance of parabolic trough solar collector system and homogenize temperature distribution on absorber tube, an innovative convergent-divergent tube was designed as PTR. The finite volume method (FVM) Monte Carlo ray tracing (MCRT) are combined simulate heat transfer process in collector. average relative error between numerical results experimental condu...

drying is a high energy consuming process. solar drying is one of the most popular methods for dehydration of agricultural products. in the present study, the performance of a forced convection solar dryer equipped with recycling air system and desiccant chamber was investigated. the solar dryer is comprised of solar collector, drying chamber, silica jell desiccant chamber, air ducts, fan and m...

In this research, a Concentrated Solar Power (CSP) as Parabolic Trough Collector (PTC), using Peltier cooling modules for power generation was analyzed by the Cross-Entropy method. When comparing conventional solar electric generators with system, we have advantage that it is compact and lightweight can be easily assembled used low-cost equipment. For perform I(V) measurements use fit models to...

introduction the significant of solar energy as a renewable energy source, clean and without damage to the environment, for the production of electricity and heat is of great importance. furthermore, due to the oil crisis as well as reducing the cost of home heating by 70%, solar energy in the past two decades has been a favorite of many researchers. solar collectors are devices for collecting ...
