How does an evaporative condenser work?

An evaporative condenser condenses the refrigerant gas inside coils that are wetted by sprayed water and cooled by an airflow. According to the evaporative cooling principle, when a small portion of water evaporates, heat is dissipated and the refrigerant condenses.

This system lowers the condensing pressure and improves efficiency compared to air-cooled condensers. It is ideal for ammonia or CO₂ systems, where energy efficiency is critical. Thermodynamic calculation software helps optimize sizing and predict seasonal performance, reducing overall electrical consumption and extending compressor life.
