Troubleshooting Low Cooling Capacity in Your Chiller

If your industrial chiller is not providing enough cooling, it can create a major "bottleneck" in your production line.

If your industrial chiller is not providing enough cooling, it can create a major "bottleneck" in your production line.

Identifying the Causes and Solutions

When the cooling capacity is insufficient, it is usually due to one of the following technical issues:

• High Condensing Pressure: If the pressure in the condenser is too high, the heat cannot be released effectively. You should investigate the cause, which is often a dirty condenser or poor ventilation.

• Low Evaporating Pressure: When the pressure in the evaporator drops too low, the cooling effect is greatly reduced. Check for refrigerant leaks or blockages in the system to fix this.

• Hot Gas Bypass Open: If the hot gas bypass valve is open when it shouldn't be, it will fight against the cooling process. You should adjust the valve settings back to the correct setpoint.

• Excessive Oil in Refrigerant: Too much oil in the refrigerant lines creates a film that blocks heat transfer. Inspect your oil return system to ensure the oil is staying where it belongs.

• Mismatched Water Flow: If the water flow through the unit does not match the machine's specifications, it cannot carry the heat away properly. Check your piping system and pump to ensure the flow is stable and correct.
