Abstract – Global energy demand is expected to increase
technology capable of converting this solar energy into thermal form is the solar concentrator or solar panel. Energy is converted in such a way that the reflected solar rays are linearly focused on the absorber, and heat is transferred from the absorber to the HTF. In general, there are different types of solar collectors, including: B. Parabolic Trough Collector (PTC), composite Parabolic Trough Collector (CPC), and Flat Plate Collector.
by more than 60% over the next few decades. Nowadays, home water heaters are getting more and more expensive, and we need to find another reliable way. Solar energy is the most useful source of clean energy to replace fossil fuels. A parabolic trough collector is one of the best ways to sustainably produce hot water. Inexpensive, easy to manufacture and easy to carry, it offers additional cost savings opportunities compared to other available models. The purpose of this research is to harness solar energy for home use. Experiments were performed using grade 204 stainless steel for the reflector and copper tubing for the absorber and mirror. The results show a slight increase in water outlet temperature compared to the simple parabolic trough collector. This document contains comprehensive content. An overview of this simple parabolic trough collector, along with geometric analysis, thermal efficiency, and applications are presented. Applications of PTC include water desalination, water heating, and increasing the power available to generate steam.
Basically, a parabolic trough concentrator that reflects solar energy directly to a receiver or absorber tube placed at the focal line of a parabola is called a parabolic trough, a type of linear concentrating solar collector. Form a light concentrator (PTC). A larger collector opening area concentrates the direct solar energy reflected onto the smaller outer surface of the receiver tube, resulting in the heating of the liquid flowing through the receiver tube. This converts solar radiation into thermal energy in the form of sensible or latent heat in the fluid. This thermal energy can be used to run the Rankine cycle to generate electricity using steam turbines in "solar thermal" power plants or to run industrial activities that require thermal energy (food industry, petrochemical industry, etc.) can. . A parabolic trough concentrator concentrates solar radiation, which is then absorbed by a receiver in the focal line, converted to thermal energy and transported to the HTF. As the man who created the second law of thermodynamics.
Key Words: Solar Energy, PTC, Household, Reflector, Absorber, Steam.
1.INTRODUCTION Solar energy is an important component of renewable resources and is considered one of the best sources of energy available to mankind. In recent decades, the energy demands of the industrial and commercial sectors have continued to grow, resulting in an over-reliance on energy generated using fossil fuel technologies, increasing the release of pollutants into the atmosphere, which contributes to global warming and environmental degradation. human health. It is interesting to note that steam is just one type of water that has changed phases in industry. Steam is used as an economical and simple means of heating in a variety of applications, including plant operations in the chemical, textile, polymer, and paint industries.
1.1 Geometric Description The geometry of parabolic shape can be defined by the following formula:
By using the aperture (W) and the focal distance (f) the rim angle (ϕr) is defined as shown below:
There are many ways to convert this solar energy into other forms of energy, such as electricity, hot water, space heating, and desalination. Currently, the most promising
