Definition of air-cooled screw machine and water-cooled screw machine
Air-cooled screw machines and water-cooled screw machines are both equipment used for refrigeration and air conditioning. The difference is that the air-cooled screw machine is cooled by air, while the water-cooled screw machine is cooled by water to reduce the temperature.
Comparison of the advantages and disadvantages of the two
The cooling efficiency of water-cooled screw machines is higher than that of air-cooled screw machines. Because water has a higher specific heat capacity than air, it has a stronger heat dissipation ability. The water-cooled screw machine can quickly cool down in a short time while saving energy. The air-cooled screw machine takes a longer time to achieve the same effect and consumes more energy.
Water-cooled screw machines require water supply and consume more water resources. At the same time, due to the principle of water cooling, the water-cooled screw machine needs to be cleaned from time to time to avoid damage to the pipeline and unit due to scale. The air-cooled screw machine does not require a large amount of water, and the maintenance of the unit is simpler.
3. Applicable scenarios
Water-cooled screw machines are suitable for scenarios that require long-term operation and heavy loads, such as large shopping malls, office buildings, factories, etc. The air-cooled screw machine is suitable for small indoor air conditioning refrigeration, such as homes, hotels, etc.
Benefit of industrial chiller applications
How to select the model of the chiller ?
In the production process, the injection molding machine needs to cool the mold to achieve rapid condensation of plastic, improve product quality, and improve production efficiency.
Here, the chiller is indispensable. Chiller used in injection molding machine, through extrusion, blow bottle, thermoplastic, hydraulic system four steps to achieve rapid condensation of plastic.
This shows the importance of the chiller to the injection molding machine. In the selection of chiller should pay attention to:
In mold cooling, the choice of ice water energy depends on its specific heat capacity with the molding material, the temperature at the time of sol, the weight, and the temperature at the time of product release.
In terms of temperature difference, the smaller the temperature difference, the more ice water flow is required to carry away the same heat, and the smaller the ice water flow is require
