Abstract:
ABSTRACT The aim of this research project is to improve the design of collector trough in terms of efficiency, lessen the heat losses and attending the sun tracker mechanism. Parabolic Trough Solar Collector (PTSC), it is constructed of multi - piece glass mirror to form the parabolic reflector (0.81.8 m) its form were checked with help of a laser and evacuated glass as receiver. Sun tracker has been developed (using two - axis) to track solar PTSC according to the direction of beam propagation of solar radiation. The storage tank is fabricated with stainless steel of size 40 L using water as a heat transfer. The experimental tests have been carried out in Baghdad climatic conditions (33.3o N, 44.4o E) during selective days of the month October. The performance of PTSC is evaluated using outdoor experimental measurements including the useful heat gain, the thermal instantaneous efficiency and the energy gained by the storage tank. The storage tank water temperature is increased from 25oc at 9:30h to 94oc at 13:30h without draw – off water. The experimental result shows the average thermal efficiency was 50% which is fairly acceptable assessment results of a PTSC locally. Keywords: Solar energy, parabolic trough solar collector, collector efficiency
