SANHUA ELECTRONIC EXPANSION VALVE DRIER (VSD1002 series)

Sanhua VSD1002 Series: Key Selling Points (KSPs)

1. Unmatched Energy Efficiency (SEER/SCOP)

• Advantage: Allows the compressor to “modulate” its capacity rather than simply turning on and off.

• Benefit: By matching the cooling/heating output exactly to the building’s demand, the VSD1002 can reduce energy consumption by up to 30–50\% compared to fixed-speed systems.

2. Compact “All-in-One” Design

• Advantage: Integrates the inverter, PFC, and control logic into a single, slim-profile module.

• Benefit: Saves significant space inside the outdoor unit cabinet. This allows manufacturers to build smaller, lighter condensing units that are easier to install in residential areas.

3. Whisper-Quiet Operation

• Advantage: Advanced FOC (Field Oriented Control) reduces motor torque ripple and vibration.

• Benefit: Eliminates the “hum” and harsh vibrations associated with older inverter technology. This makes the unit ideal for noise-sensitive residential zones where outdoor units are close to windows or neighbors.

4. Seamless “Sanhua Ecosystem” Integration

• Advantage: Designed to communicate natively with Sanhua’s SEC (EEV controllers) and pressure transmitters.

• Benefit: Provides a “Plug and Play” solution for OEMs. When the VSD, EEV, and sensors are all from the same Sanhua ecosystem, the system tuning is much faster, and the reliability of the communication is significantly higher.
