Heat Transfer Fluid

The heat transfer fluid (HTF) is the fluid circulating in the solar field cycle and transports the thermal energy to the power or storage block. The type of HTF determines the operational temperature range of the solar field and so the maximum power cycle efficiency that can be obtained ( Price et al., 2002 ).
