Thermal analysis of solar collectors.

Accepted march 2 2011 a detailed design of the evacuated tube collectors is enumerated followed by the thermal network. Accepted 10 february 2004 abstract in this paper a survey of the various types of solar thermal collectors and applications is presented. Solar thermal power plants use concentrating solar collector systems because they can produce the high temperature heat needed to generate electricity. It also gives the definitions of different features characterizing solar thermal devices.

The collector focuses or concentrates solar energy onto an absorber. This is defined as the ratio of the useful energy delivered to the energy incident on the collector aperture. Note that the presented classification is based on these features. The collector usually moves throughout the day so that it maintains a high degree of concentration on the absorber.

The temperature of each component is determined empirically. Udayakumar1 and muhammad ali2 1department of mechanical engineering bits pilani dubai. Equ 4 106 is written under the assumption that the contribution of the diffuse component of solar radiation is negligible. The main thermal loss from the absorber tube.

The thermal analysis is based on a combinat ion of the collector thermal loss from radiation convection and conduc tion. Box 20423 nicosia 2152 cyprus received 18 june 2003. The basic parameter to consider is the collector thermal efficiency. Research on pvt started during the mid 1970s focused on pvt collectors with the primary aim of increasing pv efficiency.

In this section the thermal analysis of the collectors is presented. Kalogirou cyprus university of technology limassol cyprus european cooperation in the field of scientific and technical research cost is supported by. Pvt solar collectors which basically combine the functions of a flat plate solar collector and a photovoltaic panel convert solar radiation directly into both electrical and thermal energies. A detailed design of the evacuated tube collectors is enumerated followed by the thermal network analysis of this collector.

In the introductory section the classification of the solar thermal collectors is reported. Kalogirou department of mechanical engineering higher technical institute p o.
