WebRefrigeration Cycle Video Animation. Video credit: AZVocationalTraining/ CC BY-SA 4.0 . Combustion Engine Coolants . Antifreeze, a secondary refrigerant, is a solution of glycol-based chemicals in water and can withstand temperatures below 0 degrees Celsius. Antifreeze is used to cool the engine block in combustion engines. WebThe refrigerant fluid is a mixture of water and a fluid (normally lithium bromide) with an ability to absorb water. However, it is the water that acts as the refrigerant, as it will boil at low temperatures in a partial vacuum.10. Water evaporates more quickly if the surface of a given volume is extended.
