As summer temperatures rise, ensuring your ARTECO condensing units are properly maintained is crucial for optimal performance, energy efficiency, and longevity. Proactive maintenance during the warmer months can prevent costly breakdowns and maintain consistent cooling.

Air-Cooled Condensing Units Maintenance

For air-cooled condensing units, ventilation is paramount. Begin by inspecting the unit's surroundings to confirm that discharged hot air can dissipate freely. Any obstructions to airflow will hinder the unit's ability to shed heat, leading to reduced cooling capacity and increased energy consumption.

Next, focus on the air-cooled condenser fins. These fins are susceptible to accumulating dust and dirt, which act as an insulating layer and impede heat transfer. Regularly cleaning the fins to remove dust and scale is essential. A dirty condenser reduces the chiller's cooling efficiency, forces the compressor to work harder and longer, and can lead to a cascade of problems including decreased cooling output and extended operational hours.

Finally, check the refrigerant levels. High summer temperatures can expose issues with refrigerant charge. Too much refrigerant can lead to excessive compressor pressure, potentially damaging the motor or valves. Conversely, insufficient refrigerant will significantly reduce cooling capacity, especially critical in high-temperature environments where consistent cooling is vital for preserving perishable goods.

Water-Cooled Condensing Units Maintenance

Water-cooled condensing units require a slightly different approach, primarily centered around the water circulation system. Start by inspecting and analyzing the pressure in the water condenser to determine if descaling and cleaning are necessary. For systems utilizing a cooling pond, regular cleaning of the pond is non-negotiable. Over time, sludge and debris can accumulate in the pond and be drawn into the condenser, severely impacting cooling efficiency. Adding a dilute solution of oxalic acid or citric acid to the pond and circulating it multiple times can help degrade scale buildup within the water condenser.

Additionally, inspect the cooling tower's spray nozzles and fill media. These components are vital for the cooling tower's ability to dissipate heat effectively. Ensure they are clean and functioning correctly to maintain optimal cooling performance.

Similar to air-cooled units, it's also important to check the refrigerant levels in water-cooled condensing units for the same reasons mentioned above, ensuring proper charge for efficient and reliable operation throughout the summer.
