The SET FREE $\Sigma$ series is engineered to optimize heat exchange and airflow in a compact footprint. Below are the key technical specifications and features typically associated with this model:
1. Core Performance Features
- High-Efficiency Compressor: Utilizes an advanced DC inverter scroll compressor with precise "Smooth Drive" control, which regulates refrigerant flow even at low loads to reduce energy consumption.
- Expanded Capacity: These modular units can often be combined to achieve high horsepower (HP) ratings, suitable for multi-story buildings or large industrial spaces.
- Operating Range: Designed to operate effectively in extreme ambient temperatures, often ranging from as low as -20°C for heating to 50°C for cooling.
2. Structural Design
- Top Flow Discharge: The vertical air discharge allows for units to be installed side-by-side with minimal clearance, saving significant roof or plant room space.
- $\Sigma$ (Sigma) Heat Exchanger: The unique $\Sigma$-shaped heat exchanger provides a larger surface area for heat transfer within a compact cabinet, improving the Energy Efficiency Ratio (EER) and Coefficient of Performance (COP).
- Bell-Mouth Fan Guard: The specialized grille and fan design minimize turbulence and noise while maximizing air throw.
