Have you ever worked on a 2 stage scroll compressor? Comment your thoughts below. This clip talks about copelands two stage scroll compressor and how the solenoid-driven unloading system reduces displacement. Understanding this mechanical modulation process gives technicians clearer insight into capacity control and system performance. • Solenoid engages to bypass gas • Bypass reduces compression action • Displacement decreases during unloading • Technology is fully mechanical • Helpful for diag
