Which aspects of the chiller should pay attention to:
1. How to choose the size of the chiller for injection molding machine?
When used to cool the mold of an injection molding machine, it can be calculated according to the injection volume of the injection molding machine. Under normal circumstances, a 1HP chiller is required for every 6 ounces of injection volume. For example, the customer’s factory is 100T (5.5OZS)×3; 150T (12OZS) × 4 units; 200T (23OZS) × 3 units; the size of the required chiller is (5.5×3+12×4+23×3)/6=22.25, that is, a 25HP chiller. When used for cooling of other equipment, it depends on the specific flow rate of the cooling water circulation.
2. How to select the heat preservation water tank and water pump of the chiller?
Sometimes according to the actual situation of the customer's factory, the box-type chiller may also require an external pump. At this time, the additional pump model must have the same power as the pump that comes with the chiller. If the 10HP box-type chiller comes with a pump power of 2HP, when the pump is added, it must be 2HP. The pump power requirement is the same as that of the box-type chiller of the same model. The open-type chiller is connected to the external pump.
3. Pay special attention to the appropriate temperature control of the return water of the chiller?
It is better not to be higher than 40 degrees. The higher the return water temperature, the greater the damage to the compressor and the shorter the service life!
Which of the following details should be paid attention to when installing?
1. The unit should be placed in a computer room with a room temperature of 4.4-43.3℃? Should there be enough space around and above the unit? In order to carry out daily maintenance work.
2. The place where the unit is installed must be the floor, installation mat or foundation, whose levelness is within 6.4mm? And can bear the operating weight of the unit.
3. At one end of the unit, should there be space for pipe extraction to clean the condenser tube bundle? Can also use door openings or other suitable openings.
4. Choose a water pipe with a suitable pipe diameter? What is the cooling system and chilled water system when the unit is operating at high power? And connect correctly.
5. For ordinary applications? The water flow speed through the evaporator and condenser is allowed to be between 1.0-3.6m/s.
6. Please check whether the machine is damaged before installation? And choose the right place to facilitate installation and future maintenance.
7. Under any load conditions? The water flow rate should remain stable.
