For a solar thermal system, increasing the heat transfer area can increase the output temperature of the system. However, this approach leads to a bigger and bulkier collector. It will then increase the cost and energy needed to manufacture the solar collector. This study is carried out to estimate the potential to design a smaller solar collector that can produce the same desired output temper...

In this research work 2-D CPC (Compound Parabolic Concentrator) with flat plate absorber and two parabolic reflectors is first designed and then fabricated for thermal performance analysis. Here the incident rays, after reflection from the reflector, are not focused at a point but are simply collected on a line of absorber surface. Acrylic sheets are provided to reduce the heat loss. Flat plate...

one of the effective methods to improve the thermal efficiency of solar collectors is using nanofluids as the coolant. the present study experimentally investigated the effect of sio2/water nanofluid with 1% mass fraction on the performance of a symmetric collector, i.e. conical solar collector. the conical solar collector with 1 m2 area and normal to the earth was tested in ahvaz, a city in th...

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...

An analytical analysis has been presented to evaluate the performance of a solar-assisted va-pour absorption cooling system with flat-plate absorber plate. The lithium–bromide water cycle is used obsstain effect. parameters, namely plate efficiency, collector efficiency factor, heat removal etc. have deter-mined variation fluid inlet temperature. coefficient perfor-mance (COP), COP, refrigerati...

Clean energy sources are becoming more and common, the use of solar thermal is also increasing. Indonesia gets sunlight all year round with a radiation 4.80 kWh/m2. The potential can be utilized by converting into new energy. flat plate water collector simple conversion system for hot production. This study aims to determine amount heat received collector, temperature that comes out (Tout) on e...

The thermal performance of a flat plate solar air heater coupled with thermoelectric generators has been studied. A model the collector was designed and simulations using SCILAB software were carried out to assess its performance. design by analyzing various heat mass transfer processes which occurred in components heating system. analysis resulted formulation mathematical expressions that mode...

The paper analyses the performance of a spherical solar collector compared to efficiency flat-plate collector, which is type that does not use tracking system in collecting radiation for energy conversion. Spherical benefits from constant value angle incidence, optimizes strikes absorber device and maximizes collection. Besides, geometry has larger area equal dimensions, width, length. combined...
