The Termolan SOLAR series of synthetic heat carriers is intended for use in household solar collectors, in industrial installations for generating electricity from solar energy for both northern and southern climatic zones.
Heat carriers for solar energy are used to transfer and use solar heat received through solar collectors of thermal energy.
Solar thermal collectors are usually divided into low-temperature, medium-temperature and high-temperature.
Low-temperature solar collectors use phase refrigerants and water as a heat carrier. Deterioration of water quality in certain geographical locations and high freezing temperatures make it difficult to be suitable, and, consequently, the use of water-glycol mixtures, as well as water-based nano-liquids, is gaining momentum in low-temperature applications of solar collectors. Hydrocarbons such as propane, pentane and butane are also used as refrigerants in many cases.
The heat carriers used in medium-temperature solar collectors include water, water-glycol mixtures – the resulting “green glycol”, that is, trimethylene glycol, as well as a number of natural hydrocarbon oils in various compositions, such as aromatic oils, naphthenic oils and paraffin oils in order of their increasing operating temperatures.
Heat carriers for high-temperature solar collectors is a wide range of substances, starting with water in the direct formation of steam, air, synthetic hydrocarbon oils, nanofluid compositions, molten salts, molten metals, dense suspension of solid particles of silicon carbide, etc.
Among them, synthetic hydrocarbon oils are used as the preferred liquid in most high-temperature solar collectors, while other heat carriers are used with varying degrees of commercial viability — to maximize their advantages and minimize their disadvantages.
Modern energy-efficient solar water heating systems support extreme thermal loads and require a heat carrier that does not evaporate and provides proven frost protection without phase separation in water.
