1. The principle of the refrigeration system of the chiller for cooling the mixing tank, the ice machine for cooling the mixing tank, and the freezing water machine for cooling the mixing tank is that the low-temperature and low-pressure liquid refrigerant exchanges heat with the surrounding water in the evaporator. The evaporator absorbs the heat of the water and evaporates into a low-temperature and low-pressure gas.
2.  
3. The temperature of the refrigerant remains unchanged during the evaporation process. The low-temperature and low-pressure gaseous refrigerant enters the compressor, is compressed by the compressor, and is compressed into a high-temperature and high-pressure gas, and then enters the condenser, where it exchanges heat with the indoor medium.
4.  
5. Part of the heat of the high-temperature and high-pressure gas is absorbed by the medium, the temperature of the medium rises, and the refrigerant releases heat to the condenser to become a high-temperature and high-pressure liquid.
6.  
7. The temperature of the condenser process remains unchanged, and then enters the expansion valve for throttling. Throttling is a process of rapid cooling, and the refrigerant becomes a low-temperature and low-pressure liquid.
8.  
9. After this process, the refrigerant enters the evaporator for heat exchange and evaporation, thereby realizing the entire process of the refrigeration system. This cycle is continuous, and water can be continuously cooled.

 
How to select the model of the chiller ?

1. 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.

2. 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.

3. This shows the importance of the chiller to the injection molding machine. In the selection of chiller should pay attention to:

4. 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.

5. 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
