Low-temperature brine chiller is also one of the more commonly used refrigeration equipment. Its refrigerant is the so-called brine solution, which has a low freezing point. It is especially suitable for medium and low temperature chillers to carry cold capacity. The temperature is generally required to be controlled below 0 ℃, which is usually used for the low temperature demand of some special production lines in industry. So, what kind of harm will be caused to the Brine chiller if the ratio of Brine refrigerant is not correct?
The refrigerant is used to transfer the cold and heat generated by the refrigerator to the intermediate substance of the object to be cooled or heated. The common refrigerants are air, water, brine, organic compounds and their aqueous solutions; When the outlet water temperature is 0 ℃, the commonly used water-borne refrigerant will freeze. At this time, it is necessary to select appropriate refrigerant, such as brine, glycol, etc. the selection principle is that the refrigerant in the heat exchanger will not freeze.
5. What kind of harm will be caused to the Ultra low temperature brine chiller if the ratio of brine refrigerant is not correct?
Table of service temperature and mass concentration of brine refrigerant
1、 The concentration of brine is too high or too low.
6. If the concentration of brine is increased and the specific heat is reduced, the power consumption and the relative cost of the chiller cry pump will increase; If the concentration is too small to reach the standard, it may cause the heat exchanger to freeze, the unit alarm can not work normally, and affect the normal production. Therefore, we must pay attention to the proportion of brine refrigerant when we use brine as the refrigerant of low temperature brine chiller system.
2、 The corrosively of brine to low temperature chiller and pipeline.
If the oxygen content in the solution is reduced, its corrosiveness to the low-temperature chiller and pipes will slow down. Based on this, we can use the closed brine system to reduce the contact between brine and air, so as to reduce the corrosion of low-temperature brine chillers and pipes. In addition, the corrosion can be reduced by adding preservatives to the brine to make it have appropriate acidity and alkalinity.
3、 When the density of brine carrier decreases.
Salt water refrigerant will absorb water in the air during use, which will reduce its concentration and cause the freezing point to rise. Therefore, in the process of using salt water low-temperature chiller, the density of salt water should be detected regularly. If the density decreases, the salt amount can be added appropriately to maintain the salt water concentration.
