How to dehumidify the refrigeration system of industrial refrigerators
The water content in the industrial refrigerator system comes from two aspects. One is that the vacuum is not in place, so that air and water vapor remain in the system. The other is that the refrigerant and lubricating oil of the industrial refrigerator have a certain water content.
Controlling the moisture in the refrigeration system of an industrial refrigeration unit within the allowable range is the purpose of dehumidifying the refrigeration system of an industrial refrigeration unit. So, how to dehumidify the refrigeration system of an industrial refrigerator?
1. Vacuum carefully before charging the refrigerant. The higher the vacuum, the better. Vacuuming is one of the means of dehumidification and drying in the system. The drying time of the system is related to the size of the system container, the working capacity and efficiency of the vacuum pump, the indoor temperature and the amount of moisture in the system. Generally, when the temperature and pressure of the system reach 1.7°C and 5mmHg column, it can be considered that all the air in the system has been pumped out. Then a certain amount of nitrogen is added, and the industrial refrigerator system is evacuated again to reach the above temperature and pressure. It can be considered that the drying and vacuum requirements of the system have reached the required limit.
2. When charging the industrial refrigerator system with refrigerant, the refrigeration is dried outside the machine, that is, a drying filter is installed in the charging pipeline. The drying agent includes calcium fluoride, silica gel, molecular sieve (artificial zeolite), etc. . Reduce the water content of the refrigerant entering the system to a certain extent.
3. Install a filter drier on the pipe before the high-pressure liquid pipe of the refrigeration system of the industrial refrigerator enters the thermal expansion valve to further remove the moisture and the deposits produced by the chemical reaction during operation. The desiccant generally uses 4A0 molecular sieve, and its saturated water absorption rate can reach 21-25% (mass). In order to prevent the desiccant powder from harming the system, currently most of the whole-core desiccants are used. When the desiccant filter is selected, the flow rate in the cylinder is generally selected 0.03m/s.
The above is the dehumidification method for industrial refrigerators. I hope it will be of benefit to everyone.
