Selection of power supply for air-cooled screw chiller: main power supply (three-phase) control power supply (single-phase) 380V50Hz / 220V50Hz

Scope of work:

Cooling water outlet temperature 220 ℃ to 37 ℃

The temperature difference of cooling water is 3.5 ℃ to 6.5 ℃

Chilled water outlet temperature 5 ℃ to 20 ℃

The temperature difference between the inlet and outlet of chilled water is 2.2 ℃ to 7 ℃

reminder:

1. The temperature difference of standard screw chiller is 5 degrees (20 degrees minus 15 degrees), if the standard chiller flow of a nws-10ac chiller is 3.5 cubic meters per hour.

2. Then, when you try this typhoon cooled screw chiller, you should not only look at the flow mechanism of the chiller, but also look at the temperature you need. If the temperature you try is reduced from 28 ℃ to 7 ℃, if the temperature difference of the chiller is large, then the chilled water flow per hour will be reduced from 3.5 cubic meters to 1 cubic meter. So if you want 3.5 cubic meters per hour, you have to choose a bigger model.

3. When you try the chiller, it depends on whether you are direct cooling or indirect cooling. Direct cooling is to put the water directly into the chiller and freeze the water out directly to cool the product you need. The effect will be better. Indirect cooling, for example, put the water in the basin, put a small basin on the basin, and put the product to be cooled in the small basin The effect must be worse. When you select the machine, you must consider this problem to affect the size of the horizontal.
