A glycol chiller is a chilling system that uses a percentage of glycol mixed with water to create extremely low temperatures far beyond the freezing point of water. The two types of glycol are ethylene glycol based or propylene glycol based. The antifreeze nature of glycol ensures that the coolant remains in a fluid state in order to reach its ...

May 01, 2017 The limit of water-based adsorption chillers to work around 0C evaporation temperature is overcome by using ethylene glycol as anti-freezing agent in the evaporator. Experimental results indicate that glycol remains in the evaporator and water is used as refrigerant in the adsorption process.

May 20, 2019 During rotary evaporation, the goal is to lower the boiling point of the solvent so it’s easy to recover. If not, you may contaminate the pump for a lower percentage of solvent recovery. That’s why you’ll have to know how to calculate the vapor pressure of a pure liquid by using the Clausius-Clapeyron vapor pressure formula.

persed in methanol, followed by rotary evaporation under 45 Cto remove water and ethanol. Finally, the product was dispersed in methanol again, thereby obtaining transparent methanol disper-sion of ZnO nanoparticles. EG dispersion of ZnO nanoparticles was similarly achieved by replacing KH570 with the mixture of KH570 (0.4 g) and KH550 (1.0 g).

Unlike direct expansion evaporators used in conventional refrigeration systems, glycol systems use fully flooded evaporator coils. Direct expansion evaporator coils use approximately 65% of the cooling coil in the cooling process where as glycol system evaporators are 100% filled with chilled glycol and therefor use 100% of the cooling coil in the cooling process.
