GMCC Scroll vs Rotary Compressor: Key Differences and Selection Guide

By Qishanr Compressors May 19th, 2026 130 views

When sourcing compressors for air conditioners, heat pumps, or refrigeration systems, one of the initial considerations is the selection between a scroll compressor and a rotary compressor. GMCC manufactures both types, each designed for distinct operational requirements.


Technical Comparison Overview

Parameter Rotary Compressor Scroll Compressor
Displacement range 6.8 – 60 cm³/rev 55 – 96+ cm³/rev
Cooling capacity 2 – 20 kW 17 – 35+ kW
COP (efficiency) 3.9 – 4.2 W/W 3.25 – 3.5 W/W
Noise level Lower Moderately higher
Common refrigerants R32, R290 R410A
Power supply 1φ or 3φ DC inverter 3φ DC inverter
Typical applications Residential AC, small heat pumps Commercial AC, large heat pumps


Rotary Compressor Applications

Rotary compressors are compact, quiet, and efficient for small to medium-capacity systems.

Suitable applications:

  • Residential split air conditioners

  • Small to medium heat pumps (under 20kW)

  • Dehumidifiers and portable AC units

  • Systems requiring single-phase power

Reference specification: R32, 1φ 220-240V/50Hz, 6.8 cm³/rev, 2020W cooling / 2538W heating, COP 3.9


Scroll Compressor Applications

Scroll compressors handle higher capacities and continuous operation in commercial settings.

Suitable applications:

  • Commercial air conditioners (rooftop units, VRF systems)

  • Large heat pumps (30kW and above)

  • Chillers and industrial cooling systems

  • Facilities with three-phase power

Reference specification: R410A, 3φ DC inverter, 96 cm³/rev, 31.4kW cooling, 9.66kW power input, COP 3.25


Final Recommendation

Rotary compressors are preferred for residential and small-capacity applications, while scroll compressors are suited for commercial and high-capacity systems. GMCC offers reliable solutions in both categories.
