Container Refrigeration Room Scroll Compressor

Parameter Table of Vortex Refrigeration Unit

Technical Characteristics & Working Principle

1. Smooth Scroll Compression Mechanism

Unlike reciprocating piston compressors, the Container Refrigeration Room Scroll Compressor utilizes an orbiting and fixed scroll design that creates multiple progressive compression pockets. This delivers near-continuous gas compression with significantly reduced torque variation, resulting in exceptionally low vibration and operating noise levels below 65 dB(A).

2. High Partial-Load Energy Efficiency

Cold storage environments experience fluctuating thermal loads due to door openings, product loading cycles, and seasonal weather shifts. Our system addresses this by offering optional inverter-driven variable frequency control. Compared to legacy piston units, the system yields a 15% to 20% higher Coefficient of Performance (COP) under partial loads, directly reducing your facility's operational utility bills.

3. High Reliability & Simplified Maintenance

By eliminating complex suction and discharge valve assemblies found in traditional reciprocating compressors, the mechanical wear points are drastically reduced. This streamlined architecture translates to higher reliability, lower upkeep requirements, and a design life exceeding 20,000 operating hours when properly maintained.

4. Designed for Containerized & Mobile Logistics

Engineered specifically for spatial constraints, the unit's compact footprint makes it an ideal fit for standard 20-foot and 40-foot refrigerated shipping containers, skid-mounted mobile cold rooms, and urban last-mile distribution nodes where space and weight are at a premium.

Frequently Asked Questions

What size of cold storage is suitable for this compressor unit?

The unit is primarily designed for small-to-medium cold storage rooms, containerized reefer spaces, and commercial applications. Exact sizing depends on room dimensions, thermal insulation quality, ambient temperature, and cargo thermal load rather than surface area alone. Contact our engineering team for a professional thermal load calculation.

Can variable frequency control be applied to these units?

Yes. We offer optional inverter-driven configurations. Variable frequency control modulates compressor speed dynamically to match actual cooling loads, smoothing out temperature fluctuations and lowering energy consumption during partial-load conditions.

What routine maintenance is required during operation?

Operators should routinely monitor lubricating oil levels, refrigerant return conditions, condenser coil cleanliness, and defrost timer settings. Adhering to our scheduled maintenance checklist ensures optimal performance and extends the operating lifespan beyond 20,000 hours.

Can the refrigeration unit be fully customized for custom container dimensions?

Absolutely. We specialize in custom tailoring refrigeration assemblies to match unique container layouts, specific airflow distribution paths, and localized power requirements (voltage/frequency options available for global projects).
