Solar Air Heating
The energy derived from the radiation of the sun is used in solar air heating system. Solar air heaters are used in many applications. To heat or pre heat ventilation air in different fields, installing solar air heaters is ideal. Some industries require large amount of fresh hot air for welding, painting and automotive fabrication. In agricultural buildings for drying different crops hot air is required. In commercial, institutional and multi residential buildings solar air heating is required to accomplish different tasks. Solar energy is diverted into the building's integrated air collectors.
Solar panels are used to warm air in solar air heating system. The warm air is then transmitted into the room. Solar air heater basically contains a collector panel, diffuser and a duct system. The system can be operated with a fan or without a fan. The air is distributed by the system of natural ventilation in case of system without fan. Free interior heating is provided in solar air heaters to acclaim traditional climate control system. The density of the clouds influences the output of the heat from a solar air heater. If the clouds are more naturally the amount of the sun radiations reduce. Solar air heating is suitable to any building, provided the solar panel should be placed in a proper unshed wall or roof. In the northern hemisphere it is suggestible to face southward.
The performance of a particular solar air heating is influenced by the following factors:
- The design of the solar air heating system,
- The type of the collectors like transpired-plate, glazed or unglazed,
- Resource of the energy i.e. the amount of the solar radiations that are hitting the collectors,
- Area of the project,
- Tracking mode-one axis or two axis track or fixed track
- Shading
- Efficiency
- Slope
- Physical orientation of the heater
- Air temperature of the ventilation
- Thermal resistance of the wall
- The rate of the air flow
- Operating time of the solar air heater
You can browse the internet for the models and compare the features and the cost. You can bargain on your desired model with the dealer for discounts. Mention the other companies cost. Solar air heater will cost you approximately $2500 and installation charges. The payback period will be around 15 years. A multiple language software is also available that include project, climate, product database and a user manual for solar air heating system. Software and documentation is provided at the time of installation at no extra cost.
