Aurinkolämpösoittimilla

Aurinkolämpösoitin refers to a solar thermal collector, a device designed to capture solar energy and convert it into heat. This heat is then typically used for space heating or domestic hot water. The fundamental principle behind an aurinkolämpösoitin is the absorption of sunlight by a dark-colored surface, which heats up. This heat is then transferred to a fluid, usually water or a water-glycol mixture, circulating through pipes within the collector.

There are several common types of aurinkolämpösoitin. Flat-plate collectors are the most widespread, consisting of an insulated box with a transparent cover, an absorber plate, and fluid channels. Evacuated tube collectors are another type, featuring a series of glass tubes from which air has been removed to create a vacuum. This vacuum acts as an excellent insulator, reducing heat loss and making them more efficient, especially in colder climates or during winter months.

The heated fluid from the aurinkolämpösoitin is then pumped to a storage tank. From this tank, the hot water can be used for showers, washing dishes, or distributed through a building's heating system. The amount of heat generated depends on factors such as the collector's size and efficiency, the intensity of sunlight, and the ambient temperature. Aurinkolämpösoitin systems are a renewable energy technology that can significantly reduce reliance on fossil fuels for heating purposes.
