Ethylene glycol used as carrier should be noted that when refrigerant: 1. its freezing point as the glycol concentration change in the aqueous solution varies, the concentration of ethylene glycol GB at 60% or less 220 kg, the concentration of the aqueous solution of ethylene glycol increased freezing point depression, but the concentration exceeds 60%, along with the glycol concentration, its freezing point rise, the viscosity will increase as the concentration increases. 2. The ethylene glycol containing a hydroxyl group, a long-term at 80 degrees C -90 degrees C work, glycol will first be oxidized to glycolic acid, and then is oxidized to oxalic acid, i.e. acetic acid (oxalic acid), a carboxyl group containing 2 . Oxalic acid and its byproducts will first affect the central nervous system, followed by the heart, and then affect the kidneys. 3. glycol itself is relatively active substance, readily aggregate into polymers.
