Non - freezing heat transfer liquids on the polyol platform
Solný, Tomáš ; Čáslavský, Josef (referee) ; Kotlík, Josef (advisor)
This diploma thesis is focused on the evaluation of changes in non-freezing heat transfer liquid composed of mixture of polyols and water, used in the real solar thermic system. On the base of the research a new heat transfer liquid is proposed on the platform of 1,3-polyols. The emphasis is put on the non-toxic properties of such system revealing the two chemical candidates for a new heat transfer liquid: 1,3-propanediol and glycerol. These chemicals are mixed together with water using different volume concentrations and properties of such liquids are evaluated.

Alcohols utilization as non - freezing heat transfer liquids
Kořínková, Klára ; Bednařík, Karel (referee) ; Kotlík, Josef (advisor)
This bachelor´s thesis deals with the alcohols used by the non-freezing heat transfer fluid. Were compared alcohols methanol, ethanol, ethane-1,2-diol, propane-1,2-diol and propane-1,3-diol. The substances were examined mainly from the toxicological point of view and negative impacts on human health. Toxic substance was determined by ethane-1,2-diol. Propane-1,2-diol is the most used substance in the market which is non-toxic.
