Working Principle of RUNDONGFANG Eco-Friendly Air Conditioner RDF-18B
The RUNDONGFANG Eco-Friendly Air Conditioner RDF-18B operates based on the natural physical phenomenon of "water evaporation and heat absorption". Outdoor fresh air passes through a water-soaked wet curtain, where water evaporates and absorbs heat, cooling the air. A fan then continuously delivers the cooled air indoors to achieve temperature reduction12. Key components include:
Evaporative Wet Curtain: Made of multi-layered corrugated fiber material, it maximizes water-air contact to enhance cooling efficiency
Fan System: Drives airflow to ensure continuous circulation of cooled air
Water Circulation: Maintains wet curtain moisture via a pump and water distribution system
This process reduces indoor temperatures by 5–15°C, with greater effectiveness in dry climates
Application Fields
Industrial: Automotive parts factories, hardware plants, electronics factories, machinery workshops, garment factories, pharmaceutical plants, textile mills, e-commerce logistics warehouses, etc.
Commercial: Shopping malls, internet cafes, schools, gyms, outdoor sports venues, restaurant kitchens, car washes, ticketing queues, etc.
Agricultural: Greenhouses, flower farms, plant nurseries, livestock farms, etc.
The system is energy-efficient, avoids refrigerants like Freon, and provides both cooling and humidity control
