RUNDONGFANG RDF-18B Eco-Cooling System: Advanced Adiabatic Technology
The RDF-18B leverages adiabatic evaporative cooling—a zero-refrigerant process mimicking natural thermodynamic principles. Ambient air is drawn through a nano-coated cellulose matrix saturated with water, triggering rapid evaporation that reduces air temperature by absorbing latent heat. A variable-speed centrifugal blower then propels the cooled air stream into indoor spaces, achieving a 7–18°C thermal differential relative to external conditions. Core innovations include:
Phase-Change Media: Multi-directional honeycomb-structured pads engineered for 95% humidity retention and 30% faster heat dissipation.
Smart Water Optimization: Closed-loop filtration with IoT-enabled sensors to minimize water consumption (≤2L/hour) and prevent scaling.
Dual-Mode Operation: Switchable cooling/ventilation functions with particulate filtration (PM10 removal rate: 82%).
Cross-Industry Deployment Scenarios
Heavy Industrial Zones:
Automotive forging shops, semiconductor cleanrooms, precision tooling facilities
Mitigates heat stress near injection molding presses (ambient ≤45°C) and reduces energy costs by 65% vs. conventional HVAC.
High-Traffic Commercial Hubs:

Operational Dynamics of Eco-Cooling Unit RDF-23A
The RDF-23A harnesses evaporative enthalpy exchange, a thermodynamically optimized process where ambient air undergoes adiabatic cooling via a hygrothermal transfer matrix. Fresh air is drawn through a cross-fluted cellulose composite saturated with water, inducing rapid phase-change cooling (latent heat absorption: 2,260 kJ/kg). A high-torque axial-flow impeller then delivers the conditioned airflow at velocities up to 4.5 m³/s, achieving 6–16°C thermal attenuation relative to outdoor temperatures13. Core subsystems:
Phase-Exchange Media: Laser-cut cellulose pads with 97% porosity for maximized evaporative surface area (ASHRAE 15.1-compliant cooling efficacy);
Dynamic Air Handling: Variable-frequency fan arrays with ±3% velocity control for adaptive airflow distribution;
Closed-Loop Hydration: Self-regulating water circuits with anti-scaling anodes and IoT-enabled TDS monitoring (water usage: 1.8L/kWh).
