انواع کمپرسور Compressor

Compressors are the heart of any refrigeration or air conditioning system. Their role is to compress refrigerant gas, increase its pressure, and circulate it through the HVAC cycle. The performance, efficiency, and reliability of the entire system heavily depend on the type of compressor used.

Clivet, as one of Europe’s most innovative HVAC manufacturers, utilizes a wide variety of compressor technologies across its product lines to maximize efficiency, reduce energy consumption, and meet the needs of diverse climates and building types.

Scroll Compressors

How It Works:

Two interleaved spiral scrolls compress the refrigerant in a continuous, smooth motion.

Advantages:

• Quiet operation

• High reliability with fewer moving parts

• Excellent efficiency at partial loads

• Compact size

Clivet Use Case:

Widely used in ELFOEnergy and WSAN-YMI heat pumps, scroll compressors are ideal for residential and commercial applications.

Rotary Compressors

How It Works:

A rotating roller within a cylinder compresses the refrigerant.

Advantages:

• Cost-effective

• Small and lightweight

• Ideal for low-capacity systems

• Quiet operation in small units

Clivet Use Case:

Used in compact systems like small ducted splits or room-level HVAC units.

Screw Compressors (Rotary Screw)

How It Works:

Two helical rotors mesh together to compress refrigerant as it moves along the screw chamber.

Advantages:

• High capacity for large commercial buildings

• Reliable for continuous operation

• Efficient across a wide range of loads

Clivet Use Case:

Found in large air-cooled and water-cooled chillers and commercial ClivetPack rooftop systems.

Centrifugal Compressors

How It Works:

Use a high-speed impeller to increase the velocity and pressure of refrigerant vapor.

Advantages:

• Very high efficiency at large capacities

• Oil-free options available

• Low maintenance

Clivet Use Case:

Used in central plant or district cooling systems with large-scale chillers.

Inverter-Driven Compressors (Variable-Speed)

How It Works:

The compressor speed is adjusted based on real-time demand via an inverter control.

Advantages:

• Superior energy efficiency

• Reduced wear and tear

• Precise temperature control

• Silent operation

Clivet Use Case:

Integrated in most VRF (Variable Refrigerant Flow) and multisplit systems from Clivet, offering adaptive climate control.

Reciprocating Compressors

How It Works:

Pistons compress the refrigerant by moving inside a cylinder (like a car engine).

Advantages:

• Rugged and time-tested

• Suitable for intermittent operations

• Available in open, semi-hermetic, or hermetic configurations

Clivet Use Case:

Less common in newer Clivet systems, but still found in certain legacy models and industrial applications.

Why Clivet Compressors Stand Out

Clivet selects and customizes compressors for maximum performance by:

🔹 Integrating inverter technology

🔹 Using environmentally friendly refrigerants (e.g., R32, R410A, R513A)

🔹 Ensuring full compatibility with European Ecodesign standards

🔹 Partnering with leading compressor manufacturers like Copeland, Danfoss, and Hitachi

Each Clivet unit is carefully engineered to match the best compressor for the job—ensuring optimized energy use, quiet performance, and durable operation over time.

Applications Across Industries

• Commercial Buildings: VRF systems with inverter compressors

• Industrial Cooling: Screw or centrifugal compressors in chiller plants

• Residential Homes: Scroll and rotary compressors in compact units

• Hotels & Hospitals: Modular heat pumps using multiple scroll compressors for redundancy

Maintenance and Longevity Tips

• Keep filters and condenser coils clean

• Monitor refrigerant levels

• Listen for abnormal sounds (may indicate wear)

• Schedule regular professional servicing
