Engineered for reliable operation in demanding environments.

The heat recovery efficiency exceeds 92%. The system utilizes both sensible heat (temperature difference) and latent heat (humidity difference) from indoor exhaust air as cooling air for the evaporative condenser. This innovative approach provides superior condensation effects compared to using outdoor air directly, avoiding energy losses from air conversion ventilation.

When operating in heating mode, the high-temperature, high-humidity exhaust air serves as the heat exchange source on the evaporator side. Compared to traditional central air conditioning systems, this technology saves approximately 50% of fresh air load energy consumption.

The equipment directly processes outdoor fresh air while exhausting indoor polluted air through independent channels. The air isolation heat exchange system ensures absolute air freshness and eliminates cross-contamination. Optional ozone disinfection, UV sterilization, and high-voltage electrostatic dust removal make this system ideal for hospitals and other high-requirement environments.

During transition seasons, the system uses fresh air to handle indoor loads by operating only the supply and exhaust fans, eliminating the need to start compressors. This eliminates the requirement for separate ventilation systems, resulting in significant energy savings. When temperature requirements are met but humidity control is needed, the system can treat fresh air without activating the main air conditioning system.

The integrated structure eliminates the need for outdoor units, cooling towers, and high-power cooling water pumps. This reduces initial project investment while improving efficiency. The evaporative condensing unit utilizes tubular evaporative condensing technology, maximizing water film evaporation on fin surfaces to achieve cooling and condensation through mass and heat transfer.
