Web22 de ago. de 2024 · The heat capacity of an ethylene glycol (EG)–dimethylsulfoxide (DMSO) liquid system is measured to determine its solvophobic effect. Measurements are made in the temperature range of 300–340 K for pure DMSO and the 0 to ~15 and 50 mol % ranges of DMSO concentrations. WebEthylene Glycol Fluids (EG) In most applications, EG-based fluids are preferred because of their lower cost as well as lower viscosity and resulting superior heat transfer efficiency and pumping power. For cold systems, you can use ~2% less EG than PG to achieve the same freeze protection. Propylene Glycol Fluids (PG)
The major use of ethylene glycol is as an antifreeze agent in the coolant in for example, automobiles and air-conditioning systems that either place the chiller or air handlers outside or must cool below the freezing temperature of water. In geothermal heating/cooling systems, ethylene glycol is the fluid that transports heat through the use of a geothermal heat pump.
