Thermal analysis of solar collectors.

The collector focuses or concentrates solar energy onto an absorber. Solar thermal collectors are either non concentrating or concentrating. The amount of solar radiation incident on the face of the tube can be determined from the empirical relations. This section also includes photovoltaic and hybrid photovoltaic.

In this section the thermal analysis of the collectors is presented. In effect this an alysis is only suitable for a si milar value of solar radiation. The temperature of each component is determined empirically. Thermal analysis of solar collectors.

Initially an analysis of the environmental problems related to the use of conventional sources of energy is presented and the benefits offered by renewable energy systems are outlined. A detailed design of the evacuated tube collectors is enumerated followed by the thermal network analysis of this collector. General description and thermal network of collector. Both low temperature stationary collectors and high temperature concentrating tracking collectors.

European cooperation in the field of scientific and technical research. The collector usually moves throughout the day so that it maintains a high degree of concentration on the absorber. Collectors to create a thermal circuit so that heat transfer from the surface of the collector tube to the copper tubes can be explained. An unglazed solar collector is one of the simplest forms of solar thermal technology.

Abstract in this paper a survey of the various types of solar thermal collectors and applications is presented. The basic parameter to consider is the collector thermal efficiency. Section 3 is dedicated to the optimization methodology of solar thermal collectors where it is shown how exergy analysis is used in the design of the various types of collectors. The two major types of collectors flat plate and concentrating are examined separately.

This type has no extra parts except the collector itself. Cost is supported by the eu rtd framework programme esf provides the cost office through an ec contract. The major component of any solar thermal system is the solar collector which absorbs the incoming solar radiation converts it into heat and transfers this heat to a fluid usually air water or thermal oil flowing through the collector pipes or ducts. A heat conducting material usually a dark metal or plastic absorbs sunlight and transfers the energy to a fluid passing through or behind the heat conducting surface.

Solar energy collectors are a special type of heat exchangers that convert solar radiation into thermal energy of the transport medium.
