The Impact of Cleaning a Dirty Air-Cooled Condenser on Your HVAC System

What changes occur in the system after cleaning a dirty air-cooled condenser?

When a dirty air-cooled condenser is cleaned, how does the system respond?

Changes After Cleaning a Dirty Air-Cooled Condenser

After a dirty air-cooled condenser is cleaned, the system will respond by experiencing a decrease in compressor amperage draw and subcooling, while the condenser discharge air temperature will increase.

When a dirty air-cooled condenser is cleaned, several changes take place in the system. First, the supply of flash gas to the thermostatic expansion valve becomes adequate, ensuring proper functioning and regulation of refrigerant flow. This helps maintain system efficiency and performance.

Second, the compressor amperage draw is decreased. As the condenser is cleaned, it becomes more efficient at dissipating heat, reducing the workload on the compressor and resulting in a lower amperage draw.

Third, the subcooling level decreases. Subcooling refers to the cooling of liquid refrigerant below its saturation temperature. Cleaning the condenser improves heat transfer, which reduces subcooling.

Finally, the condenser discharge air temperature increases. With the condenser no longer obstructed by dirt and debris, air can flow more freely, resulting in a higher discharge air temperature.
