A triangular solar air heating system is a type of solar heating system that is designed to capture and utilize solar energy to heat air. This type of system consists of a triangular-shaped collector, which is usually mounted on the roof or the south-facing wall of a building. The collector is made up of a series of dark-colored, heat-absorbing plates that are arranged in a triangular pattern to maximize the surface area available for solar absorption. The plates are coated with a special material that absorbs and converts the sun's energy into heat, which is then transferred to the air passing through the collector. The heated air is then directed into the building through a duct system, where it can be used to provide space heating or ventilation. In some cases, the system may also be designed to provide hot water for domestic use. Triangular solar air heating systems are highly efficient and can significantly reduce energy costs, especially in areas with ample sunlight. They are also environmentally friendly, as they do not produce any greenhouse gas emissions and do not rely on non-renewable energy sources. However, like other solar heating systems, their effectiveness is dependent on the amount of sunlight available in the area, as well as the size of the collector and the efficiency of the system's components. Solar air heating systems are a highly efficient and convenient method of absorbing solar energy and converting it to heat using moving air. The solar thermal system produces heated air. This heated air can be utilized to heat a room or to dry clothes. With the help of absorbed solar intensity radiation from the sun, these systems can produce thermal energy in the form of warm air at the output. This method of energy production is safe, clean, and environmentally friendly. It has no negative effects on the environment. This energy may be utilized in both active and passive heating systems for excessive outcomes. Space heating, crop drying, textile industry, and solar dryers are TSAH's main applications. These are low-cost, simple-to-manufacture devices that require minimum maintenance. The device aims to improve thermal and exergy efficiency, which is well-defined as the ratio of usable thermal energy output to incident solar radiation accessible during daylight hours. The amount and duration of accessible solar radiation are determined by latitude, longitude, local environmental conditions, and the season. The ability of TASH to transform incident solar energy into usable work can be used to assess its performance. By raising the velocity of flowing fluid-like air through the inside passage of the TSAH, the amount of usable energy computed by it can be increased. The ever- increasing need for power harms the environment with growing industrialization and population. One of the most serious consequences of this is climate change worldwide. Because economic progress and environmental protection are essential for human survival. A search for a more reliable and safer source began following the 1970s oil crisis, and the usage of renewable energy sources is evidence of this. Solar energy, biomass energy, wind energy, tidal energy, hydroelectric energy, and so on are all examples of renewable energy
