The cold wave is coming, and the cold winter is here. The long trousers are put into the socks to respect the winter...
Does our freezer also have to give it some anti-freezing measures? Adding to the freezer and replacing it in time can ensure the normal operation of the freezer.
So, how to choose the antifreeze for the refrigerator?
1. When choosing antifreeze products, in order to maintain the safe and stable operation of the equipment, it is necessary to periodically select a lower concentration antifreeze for replacement.
2. When purchasing antifreeze for refrigerators, you need to choose a product with a longer duration. If the chiller is used for a long time and the probability of equipment failure is low, then the cost of replacing the antifreeze for the company can be fully controlled. The longer the antifreeze is used, the lower the cost of the company to replace the antifreeze, thereby extending the service life of the chiller. The longer the life of the equipment, the higher the cost-effectiveness of the company's use of industrial chillers, ensuring that the company can complete production tasks at low cost.
When replacing antifreeze products, you need to choose an antifreeze that meets the equipment operating standards. If the operating index of the antifreeze is low, it is easy to cause common failures of the chiller and endanger the operational safety and life of the equipment. Changing the antifreeze that is suitable for the equipment can extend the service life of the antifreeze and provide conditions for saving the cost of operating industrial chillers.
The commonly used antifreezes mainly include:
①Ethanol, the freezing point and boiling point of ethanol are relatively low, in order to prevent fire, it is generally not used.
②Glycerin, mixed with water, is very expensive and not very economical.
③ Ethylene glycol. The freezing point of ethylene glycol is -11.5°C and the boiling point is 197.4P. The freezing point of ethylene glycol is as low as -68P when mixed with water. Ethylene glycol is corrosive to metals. Anti-corrosion agent should be added when preparing antifreeze. Generally, 2.5 ~ 3.5 grams of disodium hydrogen phosphate and 1 gram of dextrin are added per liter of antifreeze; ethylene glycol is highly hygroscopic, and the storage container should be sealed; B Diol is not easy to volatilize and the dosage is small during preparation, so it is widely used.
The thermal expansion of various antifreeze fluids is large, and can only be added to 95% of the total capacity of the cooling system when filling; when the antifreeze fluid is deployed, its freezing point should be 5 degrees lower than the lowest temperature in the area of use.
High-quality antifreeze can maintain the safe and stable operation of the chiller. If the company neglects the replacement of the antifreeze when maintaining the chiller, the equipment will run for a long time and be prone to high temperature failures. When the chiller is at a high temperature, it not only affects the operating power of the chiller, but also causes the operating life of the chiller to continue to shorten. The shortened lifespan of the chiller affects the cost of using the chiller for the enterprise, and the longer the chiller is used, the more energy it consumes.
