Secondary Refrigerant
The coolant, also known as the second refrigerant, is an intermediate cooling medium that transfers heat between the system to be cooled and the refrigerant, relying on sensible heat to carry cold. In air-conditioning engineering, industrial production and scientific experiments, refrigeration devices are often used to indirectly cool the object to be cooled, or the cold generated by the refrigeration device is transported over a long distance. At this time, an intermediate substance is needed to be cooled and cooled in the evaporator. Then it is used to cool the object to be cooled, which is the coolant.
High-quality coolant has the characteristics of non-toxicity, non-corrosion to metals, high specific heat, low density, low viscosity, high thermal conductivity, and low price.
Conventionally commonly used conventional refrigerants include water, salt water (sodium chloride or calcium chloride salt solution), aqueous solutions of organic compounds such as ethylene glycol or glycerol, etc.
