Anti-freezing agent and anti-freezing solution for air-conditioning system of energy generator

The invention relates to an anti-freezing agent and an anti-freezing solution for an air-conditioning system of an energy generator. The anti-freezing agent comprises the following components in percentage by weight: 65 to 80% of anhydrous magnesium chloride, 9 to 17% of anhydrous potassium acetate, 2 to 7% of anhydrous sodium acetate, 6 to 12% of urea, 1% of silver nitrate, and 1% of sodium molybdate. The anti-freezing agent shows outstanding effect on resisting rust and corrosion, and has the corrosion lower than that of water; in addition, the anti-freezing agent is added with quantity less than that of normal anti-freezing agent, and thus the cost is saved.
