R22 and R407C
Scroll Efficiency and Reliability
Smooth Scroll Movement
Qualified for R22, R407C and R410A
Wide Range Operating Envelope
Copeland Scroll TM Digital Compressors offer stepless capacity modulation in air conditioning applications and a flexible solution for R22, R407C and R410A refrigerant.
In many cooling and heating systems, load and operating conditions vary over a wide range, thus, requiring the use of capacity modulation. The Digital Scroll TM is a simple compressor solution able to assure stepless modulation down to 10% of the nominal capacity allowing for precise temperature and humidity control, superior comfort and energy saving.
This compressor range is the preferred choice for VRF, rooftop, chilled water and process cooling applications
The modulation mechanism of a Copeland Digital Scroll compressor
Compressor in loaded state operates as a standard scroll and delivers full capacity and mass ow. During the unloaded state, however, the system delivers no capacity and no mass flows through.
Varying the ‘loaded state’ and the ‘unloaded state’ times, any capacity between 10% and 100% can be delivered by the compressor.
