Scroll compressors are widely used in modern HVAC systems due to their reliability, efficiency, and compact size. They utilize two interleaved spiral-shaped scrolls to compress refrigerant smoothly and quietly, making them ideal for residential, commercial, and industrial applications.
Clivet incorporates various types of scroll compressors in its cutting-edge HVAC solutions, offering optimized performance and energy savings.
Fixed Scroll Compressor
Description
- Operates at a constant speed with a fixed displacement.
- Simple design with fewer moving parts.
- Provides reliable and efficient compression for steady-load applications.
- Advantages
- Durable and low maintenance.
- Lower initial cost.
- Suitable for systems with consistent cooling or heating demand.
- Typical Clivet Applications
- Basic residential and light commercial air conditioners.
- Systems where load variation is minimal.
- Variable Speed (Inverter-driven) Scroll Compressor
Description
- Equipped with a variable frequency drive (VFD) to control motor speed.
- Adjusts compressor capacity based on cooling or heating demand.
- Offers precise temperature control and improved energy efficiency.
Advantages
- Significant energy savings during partial loads.
- Reduced wear and tear due to soft start/stop.
- Enhanced comfort with stable temperature maintenance.
Typical Clivet Applications
- Advanced VRF systems.
- High-efficiency heat pumps and chillers.
- Commercial and large residential HVAC systems.
Two-Stage Scroll Compressor
Description
- Contains two scroll stages operating in sequence to achieve higher pressure ratios.
- Improves efficiency for applications requiring variable pressures.
- Typically designed for refrigeration and industrial applications.
Advantages
- Better energy performance in specific applications.
- Handles a wider range of operating conditions.
- Enhanced reliability due to staged compression.
Typical Clivet Applications
- Industrial HVAC units.
- Large-scale chillers requiring high pressure lift.
Tandem Scroll Compressor
Description
- Features two or more scroll compressors assembled in tandem within the same housing.
- Provides higher capacity and redundancy.
- Can operate individual scrolls independently for load matching.
Advantages
- Increased system capacity without increasing unit size.
- Enhanced reliability via compressor staging.
- Energy savings through capacity modulation.
Typical Clivet Applications
- Large commercial HVAC systems.
- Modular chillers.
- Systems requiring flexible capacity control.
Clivet and Scroll Compressors
Clivet utilizes scroll compressors extensively across its product range due to their efficiency and adaptability. The choice of fixed, variable speed, two-stage, or tandem scroll compressors depends on system requirements, desired efficiency levels, and application scale.
