When purchasing a screw chiller, it is necessary to fully consider that the cooling capacity matches the needs of the place of use, the working environment is suitable for air cooling or water cooling, the type of refrigerant meets the requirements and needs of environmental protection, and the brand and grade of the compressor are high; the control system is automatically controlled to realize intelligent adjustment and automatic operation; power and energy consumption are low noise, low power, and high efficiency, and maintenance and services have comprehensive after-sales service and maintenance support.
In many industrial productions, such as mechanical processing, coating, mechanical processing, and chemical synthesis processes, screw chillers will generate heat during the operation of the equipment. When the heat cannot be dissipated in time, it will affect the normal operation of the equipment, the quality of the product and its production efficiency.
How to choose the right screw type screw chiller:
1. Chilled water volume: Usually when the production equipment or production raw materials are being processed, when it needs to be cooled, there will be a temperature difference between the screw chiller and the pipeline inlet and outlet of the production equipment. This temperature difference is the heat generated by the production equipment, and it needs to be clearly explained to the chiller manufacturer.
2.Cooling capacity basis: According to the needs of the place of use, select the corresponding cooling capacity, and avoid the selection of screw chillers with too large or too small cooling capacity. If the cooling capacity is too small, it will not be able to cool down. If it is small, it will reduce productivity, and if it is large, it will cause the equipment to run. The quality of cooling has a lot to do with the water temperature and flow rate. The matching cooling capacity is still very critical.
1. Solution properties of production and processing materials: When using it, it is also necessary to know the maximum and minimum temperatures that the production equipment and its materials cannot withstand, and the acid and alkali resistance characteristics, so as not to affect the equipment or materials. If we want to avoid these situations, we must learn to correctly use the density, weight, specific heat, and volume of equipment parts or raw materials for production and processing.
2. Equipment cooling medium: Usually, food, grease, tap water, sea water, drinks, etc. are used in daily life, such as tap water for mold cooling or cooling, and electroplating electrolyte cooling needs to be cooled by chilled water in the coil. However, in some processes, ethylene glycol, alcohol, and brine are used as refrigerants. The application environments and media of screw chillers are different, so it is necessary to find a chiller manufacturer to customize.
3.Working environment: choose air cooling or water cooling according to the working environment. If you work in a small environment, you should choose a small unit to save space.
1. Maintenance and service: Choose a screw chiller with comprehensive after-sales service and maintenance support to ensure that the equipment can operate safely for a long time.
Choose air-cooled or water-cooled screw chiller?
The water-cooled screw chiller itself cools, so it is called water-cooled. There will be two more water pipes on the pipeline than the air-cooled screw chiller, but the water-cooled effect is much better than the air-cooled, and the air-cooled chiller is much easier to install, so friends in the industry can choose according to their own.
To sum up, when purchasing a screw chiller, it is necessary to fully consider various factors and properly balance the various points in order to select the most suitable screw chiller for you, realize energy saving and environmental protection benefits, and improve production efficiency and corporate competitiveness.
