Industrial chiller is a kind of high-efficiency refrigeration equipment widely used in industrial production. It can provide great help for various industrial productions. However, if the antifreeze position of the low-temperature chiller has dropped, it needs to be dealt with in time. In order not to affect the stable operation of the equipment, or even reduce the overall cooling performance of the equipment, to increase the antifreeze capacity of the low-temperature chiller in low-temperature areas requires the following skills

1. For the screw chiller, the amount of antifreeze is not the better, and when adding, the overall concentration of the antifreeze can be reduced, and the best filling effect can be obtained. The lower the concentration, the smallest range of influence on the screw chiller during operation. By carefully analyzing the operating environment and adding a suitable amount of antifreeze for screw chillers, the probability of equipment failure can be reduced.

2. The shorter the replacement period of antifreeze, the better. When using a screw chiller, in order to maintain the safe and stable operation of the equipment, it is necessary to determine the specific replacement period of the antifreeze of the screw chiller according to the use environment. The shorter the replacement cycle is, the stability of the antifreeze can be maintained, so as to achieve the effect of protecting the stable operation of the screw chiller.

It can be said that antifreeze is a professional condensing agent necessary for professional refrigeration of many industrial chiller products, and it is also an efficient refrigeration substance. For industrial chillers, the amount of antifreeze is not the better, and when adding, the overall concentration of the antifreeze can be reduced, and the best filling effect can be obtained.

Industrial chillers also have industry specifications and standards for antifreeze requirements. When using antifreeze, they must be used in accordance with the application standards. The lower the concentration, the various impacts on the industrial chiller during operation. At the minimum, by carefully analyzing the operating environment and adding a suitable amount of antifreeze for low-temperature chillers, the probability of equipment failure can be reduced. Both chillers and low-temperature chillers are inseparable from antifreeze.

In winter, the use of industrial chillers is inseparable from the addition of antifreeze. The full name of its antifreeze is called antifreeze coolant, which means a coolant with antifreeze function, which is mainly used for antifreeze in the winter.

The requirements of Oumal industrial chiller for antifreeze performance:

1. Stable chemical performance.

2. Good antifreeze performance.

3. The low temperature viscosity is not too big.

4. Anti-corrosion and anti-rust properties.

5. It has no swelling and corrosive properties to rubber sealed conduits.

How to choose the antifreeze for the chiller?

In order to greatly improve the cooling performance of the chiller, after a period of use, users need to maintain the chiller regularly. During maintenance, especially in winter, do not neglect to replace the antifreeze for the chiller. If the chiller is maintained without replacing or adding antifreeze, the cold temperature in winter can easily cause freezing of the pipe. When the chiller is operated for a long time, the equipment is prone to various common failures, which will seriously affect the service life of the equipment , Even leading to the continuous increase in the cost of using the chiller.

High-quality antifreeze can not only maintain the safe and stable operation of the chiller. If the replacement of the antifreeze is often neglected when the chiller is maintained, 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 the company's use of the chiller, and the longer the company uses the chiller, the more energy it consumes.

So, how to choose the antifreeze for the chiller?

1. When choosing an antifreeze product, 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 buying antifreeze for chillers, you need to choose a product with a longer period of time. 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 replacing the antifreeze, thereby extending the 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. Replacing the antifreeze that is suitable for the equipment can prolong the service life of the antifreeze and provide conditions for saving the cost of operating industrial chillers.

The commonly used antifreezes mainly include:

① Ethanol, 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 197.4°C, and the lowest freezing point after mixing with water can reach -68°C; ethylene glycol is easy to corrode metals, and anti-corrosion agent should be added when preparing antifreeze. Generally, add 2.5 to 3.5 grams of disodium hydrogen phosphate and 1 gram of dextrin per liter of antifreeze; ethylene glycol has strong hygroscopicity, and the storage container should be sealed; ethylene glycol is not easy to volatile, and the amount used in preparation is small, so it is widely used. The thermal expansion of various antifreeze fluids is relatively 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.
