Chillers To Pay Attention To Several Aspects
1. Injection molding machine dedicated chiller model size choice
For the injection molding machine mold cooling, according to the injection molding machine to calculate the amount of injection, under normal circumstances, every 6 ounces of injection need to use 1HP chiller, for example: customer factory for 100T (5.5OZS) × 3; 150T (12OZS) × 4 units; 200T (23OZS) × 3; the required chiller size (5.5 × 3 +12 × 4 +23 × 3) /6=22.25, that is, need to use 25HP chiller. For the cooling of other equipment, depending on the specific flow rate of the cooling water cycle.
2. Chiller water tank and water pump selection
Sometimes according to the actual situation of the customer factory, box-type chiller may also need to add a pump, this time plus the pump model must be in the chiller with the same pump power. Such as 10HP box chiller comes with pump power 2HP, then the pump, also need to be 2HP.
When the pump power requirements and the same type of box chiller requirements the same open chiller, in the external pump.
3. Chiller back to the water temperature, preferably not higher than 40 degrees, the higher the return water temperature, the greater the damage to the compressor
