Absorberilevyn

Absorberilevyn, also known as an absorber plate, is a component primarily used in passive solar heating systems. Its main function is to capture and convert solar radiation into heat. Typically, an absorber plate is a dark-colored, often black, metal sheet designed to maximize the absorption of sunlight. This absorbed solar energy is then transferred to a fluid, which can be air or a liquid like water or a glycol mixture.

The design of an absorber plate is crucial for its efficiency. Its surface is often coated with selective coatings that enhance solar absorption while minimizing thermal re-emission. The plate is usually housed within an insulated casing, often part of a solar collector unit, to prevent heat loss to the surroundings. The fluid flowing behind or through the absorber plate picks up the heat and transports it to where it is needed, such as for space heating or water heating.

Absorber plates are a fundamental element in many types of solar thermal collectors, including flat-plate collectors and evacuated tube collectors. Their presence allows for the harnessing of solar energy for various thermal applications, contributing to renewable energy generation and reducing reliance on fossil fuels. The material, shape, and surface treatment of the absorber plate are all optimized to achieve the highest possible thermal efficiency.
