Technical Specifications:

• Compressor Type: Reciprocating, hermetically sealed
• Refrigerant Compatibility: R600a (Isobutane) / R134a
• Voltage Rating: 220–240V / 50Hz
• Rated Power Input: 120W–145W (depending on operating condition)
• Displacement Volume: Approximately 9.8 cm³/rev
• Operating Pressure Range: Suction 0.15–0.45 MPa / Discharge 1.2–2.0 MPa
• Rotation Speed: 2850–3000 RPM
• Noise Level: ≤ 52 dB(A)

Material Composition:

• Cylinder Block: Cast iron with internal anti-wear coating
• Piston: Aluminum alloy with PTFE-coated skirt
• Crankshaft: Carbon steel, dynamically balanced
• Valve Plate: Spring steel with PEEK reed valves
• Housing: Welded steel shell with epoxy anti-corrosion coating
• Windings: Copper enamel wire, Class H insulation

Structural Features:

• Fully hermetically sealed unit with no external shaft seal
• Internal suction accumulator for liquid refrigerant protection
• Rubber vibration isolation mounts (4-point mounting)
• Rear-mounted electrical terminal box with overload protector

Working Principle: The reciprocating piston draws low-pressure refrigerant vapor through the suction line, compresses it to high-pressure superheated vapor via the crankshaft-driven piston stroke, and discharges it through the discharge valve into the condenser circuit. The hermetic seal ensures zero refrigerant leakage throughout the operational lifecycle.

Advantages:

• Zero maintenance sealed design eliminates oil leakage risk
• High energy efficiency with optimized compression ratio
• Ultra-low vibration due to dynamic balancing of rotating assembly
• Extended operational lifespan exceeding 15 years under normal conditions

Applicable Industries: Domestic refrigerator manufacturing, commercial display coolers, wine cabinets, beverage coolers

Installation Requirements:

• Must be mounted upright within ±5° tolerance
• Minimum 10mm clearance from rear wall for heat dissipation
• Electrical connection via dedicated 16A circuit with thermal overload protection
• Refrigerant line brazing must use nitrogen purge to prevent internal oxidation

Usage Precautions:

• Never operate without refrigerant charge — causes compressor seizure
• Ensure stable voltage supply within ±10% of rated value
• Do not tilt compressor beyond 45° during transport or installation
