What are the common design points of screw chillers
1. Refrigerating capacity
The refrigerating capacity of water chillers is directly related to the normal use and operating efficiency of production equipment. If the refrigerating capacity is too small, the ideal refrigerating effect cannot be achieved. The production efficiency is slightly reduced, the operation energy consumption is increased, and the production equipment can operate normally only after the production line is shut down. However, if the model selection is too large, it will waste energy and increase the operation cost
2. Chilled water volume
The amount of cold water, that is, the ice water cooled by the chiller, directly acts on the cooled part, but due to the size of the water flow, it directly affects the heat transfer effect. The flow rate is calculated according to the material, density and heat transfer ratio of the cooled parts. It is obvious that some equipment need cooling flow rate because the amount of water is insufficient for cooling. No. Therefore, the water flow has a direct relationship with the operation of the chiller and the cooling effect of the production equipment.
3. Inlet and outlet temperature
When the production equipment or raw materials are processed in the production process and cooling is required, there will be a temperature difference between the inlet and outlet of the pipeline connecting the chiller and the production equipment. This temperature difference is the actual heat generated by the production equipment, so the cooler can be calculated and selected quite accurately.
4. Understand the volume, weight, specific heat and density of cooling equipment or raw materials for production and processing.
This can quickly and effectively calculate the cooling capacity of the required refrigerator. At the same time, record the time required for the initial temperature of the cooling material to drop to the target temperature, which is also the method for calculating the refrigerating capacity. Have a clear understanding of the production equipment or materials required or capable of withstanding and temperature, so as to avoid the impact on the equipment or materials.
