If the weather is cold, it is easy to frost. In some cold regions, the chiller can’t escape this bad luck. Once the chiller is frosted, it will reduce its operating efficiency and affect the cooling effect. Therefore, it is necessary to carry out the defrosting process in time, and the specific method has been explained in detail.
1. Hot gas frost storage
This method is mainly realized by using the heat released by the superheated steam discharged from the compressor during the condensation process. This heat can easily remove the frost layer on the surface of the evaporator. melt away. The reason why this method can be widely used is mainly due to its strong applicability and the fact that the oil in the machine can be flushed out during the defrosting process. There are also some limitations, that is, the entire defrosting time will be relatively long, which will have a certain impact on the storage temperature.
2. Water flushing
It is very simple, that is, the flushing water is sprayed on the surface of the chiller evaporator through the spray device, so that the double layer is melted and then discharged through the drainage pipe. This method is ideal because it has advantages in terms of efficiency, operation, and impact.
3. Electric defrosting
The principle of electric defrosting is similar to that of hot gas defrosting, except that electric defrosting uses electric heating elements to heat the evaporator to defrost. Moreover, the electric heating defrosting system is relatively simple, and it is easy to realize automatic dry ceremony. The only disadvantage is that it consumes too much power.
The specific method to be used to defrost the chiller should be determined according to the actual situation. It can also be a combination of several methods. Try to choose the method with the best defrosting effect and relatively low energy consumption.
