The SPL series evaporative condensers represent an advanced heat exchange device developed through the integration and refinement of cutting-edge thermal exchange technologies from both domestic and international sources.

Utilising water and air as cooling media, the SPL series evaporative condensers facilitate heat exchange with high-temperature gaseous refrigerant within the coil, causing the refrigerant to condense from a gaseous to a liquid state. Internal components include a water distribution system, condensing coil assembly, packing heat exchange layer, and water separator. Externally, it incorporates a circulating water pump, an electronic water descaler, and an axial fan positioned at the top of the coil side. The axial fan creates a negative pressure environment within the unit. During operation, cooling water is distributed through the water distribution system and, driven by the powerful airflow, evenly and completely covers the coil surface. The high-temperature gaseous refrigerant enters from the top of the coils, and the condensed liquid refrigerant exits from the coil’s base. During this process, the high-temperature refrigerant undergoes heat exchange with the water and air surrounding the coil, with the airflow significantly enhancing the heat transfer efficiency. The cooling water and air absorb heat, causing their temperatures to rise sharply. Part of the cooling water vaporises into water vapour, and this evaporation carries away substantial heat, which is drawn out by the fan and discharged into the atmosphere. simultaneously, moisture within the hot air is captured by the demister and directed into the sump. Unvaporised high-temperature cooling water flows into the packing heat exchange layer, where it is cooled by the passing air. After thorough cooling, the water returns to the sump to be recirculated by the pump back into the water distribution system for continued operation. Water lost to the atmosphere is replenished in a timely manner, controlled by the float valve in the sump.

Counterflow Evaporative Cooling:

Gaseous refrigerant flows upward while sprayed water cascades downward under gravity from the top. Air typically traverses the tube bundle from bottom to top. Consequently, at the bottom of the heat exchange tube bundle, the lowest-temperature liquid refrigerant exchanges heat with water and air that have already warmed but remain relatively cool. At the top, the higher-temperature gaseous refrigerant contacts the incoming cool air and spray water. Throughout the entire heat exchange process, a substantial logarithmic mean temperature difference is maintained along the entire length, resulting in higher heat transfer efficiency.
