In industrial production, the equipment will generate heat during operation. If the heat cannot be dissipated in time, it will affect the normal operation of the equipment and the quality and production efficiency of the product. At this time, a chiller is required. But after determining the use of the chiller, what are the use parameters and requirements for the chiller selection?

1. Cooling capacity

The cooling capacity of the chiller is directly related to the normal use of production equipment and operating efficiency. If the cooling capacity is too small, the ideal cooling effect cannot be achieved, and the production efficiency will be reduced in light of the light, and the operating energy consumption will increase. Normal operation until the production line is stopped. However, if the selection is too large, it will waste energy and increase the operating cost, and the larger the cooling capacity of the chiller, the higher the price of the chiller. Therefore, the matching cooling capacity is very important.

2. The amount of chilled water

The amount of chilled water is the ice water cooled by the chiller, which directly acts on the part to be cooled, but because of the size of the water flow, it will directly affect the heat exchange effect. This flow rate is based on the material, density and heat exchange ratio of the cooled part. Calculated, and some equipment clearly requires cooling flow, because the water volume is not enough, it cannot be cooled down. Therefore, the water flow is directly related to the operation of the chiller and the cooling effect of the production equipment.

3. Inlet and outlet temperature

When the production equipment or production raw materials need to be cooled during production and processing, 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 heat actually generated by the production equipment, so it can be quite accurate. Calculation and selection of chiller.

4. Cooling medium

The cooling medium generally includes: tap water, ethylene glycol solution, oil, seawater, food and beverage, etc.

5. Volume, weight, specific heat, density of raw materials for production and processing

In this way, the cooling capacity of the required chiller can be calculated quickly and effectively. At the same time, note down the time required for the initial temperature of the cooled material to drop to the target temperature, which is also the way to calculate the cooling capacity. There is also a clear understanding of the highest and lowest temperatures that the production equipment or materials need or can withstand, so as not to affect the equipment or materials.

6. Air-cooled chiller or water-cooled chiller

Although both air-cooled chillers and water-cooled chillers are chillers, the cooling methods of the units themselves are different, so the installation methods are also different. The air-cooled type is more convenient, and it can be operated by connecting the water pipe and power supply, but the cooling effect is slightly worse than that of the water-cooled chiller, because the cooling method of the air-cooled chiller is air, and the air is greatly affected by the ambient temperature, and The group installation location also requires space around the chiller.

The water-cooled chiller is called water-cooled because it uses water to cool itself. The water-cooled chiller needs to install a cooling tower to cool the unit. There are two more water pipes in the pipeline engineering than the air-cooled chiller, but the water-cooled chiller The cooling effect of the chiller is much better than that of the air-cooled chiller, and it can even be a smaller model than the air-cooled chiller, so most users will choose a water-cooled chiller under installation conditions.

The use parameters and requirements for the selection of the chiller are shared here. The chiller is usually used in injection and blow molding in the plastics industry, metal processing cutting oil, welding equipment, die casting and machining, chemical processing, pharmaceutical formulation, food and Beverage processing, papermaking, cement processing, vacuum systems, X-ray diffraction, power supply and power stations, analytical equipment, semiconductors, compressed air and gas cooling.
