Inverter Swing Rotary Compressors
The Copeland inverter swing rotary compressor platform delivers high performance, energy efficiency and competitive value in residential HVAC applications that require variable-capacity modulation.
Optimized for residential heat pump performance
As the residential heating, ventilation and air conditioning (HVAC) industry transitions from fossil-fuel heating to energy-efficient heat pumps, variable-capacity compressors are needed to meet efficiency targets and comfort requirements. Copeland inverter swing rotary compressors are designed to address this growing demand, offering competitive performance in the 1–5-ton range.
- Optimized for use with low-global warming potential (GWP) A2L refrigerants R-454B and R-32
- Innovative swing rotary design integrates vane and roller, eliminating springs, enhancing reliability and preventing leaks
- High-speed platform enables high part-load performance with improved sound and vibration control
- Large turndown ratio delivers flexibility across operating conditions within a compact footprint
- Integrated Copeland EV4 variable frequency drive (VFD) platform simplifies system design application
- Exceptional global service and customer support network with manufacturing and distribution resources
How Copeland inverter swing rotary compression technology works
Copeland inverter swing rotary compressors feature an innovative design that integrates the vane and roller into a single unit. This eliminates the need for springs, reducing component wear and minimizing gas leakage between intake and discharge chambers. The integrated piston oscillates, guided by a swing bushing, maintaining linear contact at the vane base during operation. This design is particularly effective at high rotation speeds during full-load conditions, where traditional rotary compressors can experience efficiency losses. The result is consistent performance across a wide operating envelope with enhanced reliability and reduced maintenance requirements.
Expanding options for variable-capacity compressors
The Copeland inverter swing rotary compressor platform features seamless integration with the EV4 variable frequency drive, which can also be paired with Copeland’s variable-speed scroll compressors. This unified, complementary approach to compressor and drive integration provides system designers and manufacturers with an expanding portfolio of reliable, flexible solutions for variable-capacity compressor applications.
