Why are there two cooling methods for the chilled water of the เครื่องทำความเย็น?

There are two ways to supply chilled water as the target. One is direct cooling and the other is indirect cooling. Although you may find it a bit rusty, it is very simple to understand!

Direct cooling: direct cooling means that the chilled water of the chiller is used as the target for direct cooling, without any interval, or the target is put into the cooling water. For the electroplating industry, in many cases, the chilled water is direct Cool down, the cooling target will be directly placed in the frozen water.

Indirect cooling: For the most common plastic machine, if you want to cool down the mold when the plastic mold is being produced (because the injection molding machine has hot liquid plastic injected into the molding hole of the mold, so high temperature is generated), just The temperature must be lowered through the water pipe hole of the mold itself, which is generally understood as indirect cooling.

The two chilled water cooling methods seem to be better for direct cooling, but there is no substantial difference between the advantages and disadvantages of the two, because whether it is direct cooling or indirect cooling, it is based on actual demand. Yes, there is no good or bad.
