In air-conditioning engineering, industrial production and scientific experiments, coolant devices are often used to indirectly cool the objects to be cooled, or the cooling capacity generated by the refrigeration device is transmitted over a long distance, which can solve some problems that are difficult to be solved by direct cooling refrigeration devices.

Due to the simple operation and maintenance of the system, some problems are often ignored.There is a cold storage water tank in the secondary pump circulation system. Generally, the water tank is open and connected with the atmosphere. In the long-term use process, because the water vapor partial pressure of the air is greater than the surface partial pressure of the coolant solution, the water in the air will enter the system.For some small systems, the impact of freezing point is more obvious, so small systems need to test and record their freezing point on one side every two to three months.Due to the large volume of the large system, the opening of the water tank is treated with a breather valve. Due to the relatively small amount of water migration, the measurement and recording time can be once a year. If problems are found, they can be handled as soon as possible to reduce the cost of adjusting and distributing the coolant in the later stage.The above is mainly for the maintenance of water-soluble coolant system.

For the non water permeable coolant system, the closed system is generally considered in the design process, and the coolant storage tank is also sealed by nitrogen to prevent moisture from entering.During the operation and maintenance of such systems, it is necessary to record and compare the pressure of the system. During the equipment maintenance process, air or some impurities will inevitably enter, which will accumulate at the filter in front of the water pump and coolant heat exchanger, and the moisture in the air will become ice. At this time, the pressure at the inlet of the pump will be low. If it is lower than the atmospheric pressure, air will invade the system and produce a vicious cycle, Therefore, this item needs to be included in the inspection process of the system.

Although the operation and maintenance of the coolant system is simple, it still needs fine management. Glacier coolant focuses on the coolant and application system, and provides professional operation and maintenance solutions.
