Web1 Introduction Heat transfer fluid (HTF) is primarily used as an intermediate fluid to transfer heat from a heat source to other heat demands (or cold streams). Single heater can provide heat to any number of cold streams through HTF. WebFactors Affecting Freezing Point [Click Here for Sample Questions] The main factors are the type of molecules the liquid is made up of. If the intermolecular forces between its molecules are strong, there's a high freezing point. When intermolecular forces of attraction between the molecules are weak, then its freezing point is fairly low
