Nanjing Kaierini specializes in the production and sales of air-cooled box chillers. The unit is equipped with multiple protection devices to ensure safe operation of the unit. It is suitable for industrial use for 24 hours without stopping. If the user wants to ensure that the air-cooled box chiller has high cooling efficiency and long service life, it must be remembered to do regular maintenance. The following are the precautions for routine maintenance of the unit.
1. Check the stability of voltage and current
When the air-cooled box chiller is working normally, the voltage is 380V, and the current is normal within the range of 11A-15A;
2. Check if the refrigerant is reduced.
This can be judged based on the high and low pressure gauge values ​​on the front of the air-cooled box chiller. When the chiller is in normal operation, the high pressure is 11-17kg, and the low pressure is 3-5kg. In the shutdown state, the high pressure and low pressure are all around 0.6kg;
3, regular cleaning system
When the air-cooled box chiller is running for 6 months, the whole system should be cleaned, such as pipes, filters, condensers, fans, etc., especially the fan, like our common fan, which is covered with dust and affects heat dissipation, so the cooling efficiency Will be directly reduced.
Air-cooled chillers, referred to as air-cooled chillers, are also known as air-cooled box chillers, air-cooled screw chillers, air-cooled low-temperature chillers, air-cooled piston chillers, and so on. It is one of our commonly used chillers.
Since zui is commonly used, what are its unique characteristics? What problems should we pay attention to when installing and using?
Air-cooled box chiller performance characteristics:
1. The air-cooled box chiller does not need to be equipped with a water pump or a cooling tower. It does not require a cooling tower to replenish water. The water system is clean and easy to use. It has advantages in areas with water shortages, super high-rise buildings and high environmental requirements.
2. The air-cooled chiller uses air as the cooling medium, and the air density is small, the specific heat capacity is small, and under the same heat, the required air volume is large, so the required heat exchange area is large, and the production cost and the selling price are high.
3. Under full load, the air-cooled chiller consumes more power than the water-cooled chiller, but the air-cooled chiller can greatly reduce the power consumption when the outdoor dry bulb temperature drops.
In general, according to the usage habits, the air-cooled chiller has no higher annual energy consumption than the water-cooled chiller, and the water-cooled chiller has higher equipment maintenance costs than the air-cooled chiller. The operation and maintenance costs of the chiller may also be slightly lower than that of the water-cooled chiller.
Carbomer is an acrylic resin obtained by cross-linking pentaerythritol with acrylic acid. It is a very important rheological regulator. After neutralization, carbomer is an excellent gel matrix, which has important applications such as thickening suspension. According to the dry product calculation, including carboxylic acid group (-cooh) should be 56.0 % ~ 68.0%.
Common carbopol series include: Carbopol 940, 941, 934, 1342, 980, ETD 2020, AQUA sf-1, Ultrez 21, Ultrez 20, etc.
