HVAC Input Plenum With Electrostatic Grid for Fine Particle Capture

The patent introduces a precharging electrode as an intermediary component between the air inlet and the collecting electrode. This precharging electrode imparts electrical charge to particles in the micron and sub-micron range, enabling them to be attracted to and captured by the collecting electrode. The intermediary precharging mechanism bridges the gap between simple filtration and complex electrostatic precipitation, achieving high-efficiency particle capture without excessive system complexity.

The patent designs a universal air purification system that can be effectively applied to both commercial and residential buildings. The system uses a modular electrostatic precipitation mechanism with adjustable parameters (such as voltage and flow rate) that can be optimized for different building types and occupancy levels. This multi-functional design allows the same core technology to serve diverse applications, from small residential units to large commercial spaces, thereby expanding adaptability while maintaining high particle removal efficiency.

The patent optimizes the electrical field parameters to achieve effective particle purification with reduced energy consumption. By carefully selecting and adjusting parameters such as voltage gradient, electrode spacing, and air flow velocity, the system achieves high particle capture efficiency without requiring excessively complex or high-energy electrical fields. The parameter optimization allows the system to operate efficiently in air recirculation mode, minimizing energy loss while maintaining effective purification performance.
