Commercial and Residential Solutions
The 2nd generation Copeland Scroll two-stage compressor is built upon the proven Copeland Scroll platform and is typically used in split and packaged air conditioning or heat pump systems.
The digital scroll is capable of seamlessly modulating its capacity from 10% to 100%. A normally closed (de-energized) solenoid valve is a key component for achieving modulation. When the solenoid valve is in its normally closed position, the compressor operates at full capacity, or loaded state. When the solenoid valve is energized, the two scroll elements move apart axially, or into the unloaded state. During the unloaded state, the compressor motor continues running, but since the scrolls are separated, there is no compression. During the loaded state, the compressor delivers 100% capacity and during the unloaded state, the compressor delivers 0% capacity. A cycle consists of one loaded state and one unloaded state.By varying the time of the loaded state and the unloaded state, an average capacity is obtained. The lowest achievable capacity is 10% which equates to 1.5 seconds of pumping during one 15 second cycle. An example for the 15 second controller cycle: In any 15 second cycle, if the loaded time is 10 seconds and the unloaded time is 5 seconds, the average capacity is 66% or if the loaded time is 5 seconds and the unloaded time is 10 seconds the capacity during that 15 second period is 33%. See Figure 1 for a graphical representation of the digital cycle, and Figure 4 for a graph showing solenoid on-time vs. compressor capacity.
How it Works
The digital scroll compressor unloads by taking advantage of the Copeland Scroll compressor's axial compliance. All Copeland Scroll compressors are designed so that the compression elements can separate axially a few thousands of an inch. The ZPD34-ZPD54K5, ZPD61-ZPD83KC, ZPD91KC, ZPD104KCE, ZPD122KCE, and ZRD36-81KC compressors described in this bulletin use a lift piston mechanism to separate the scrolls during the unloaded
state. When the solenoid is energized the volume on top of the piston is vented to the low side allowing the piston
and fixed scroll assembly to move axial away from the orbiting scroll. When the solenoid is de-energized the piston is forced down and the scrolls are loaded axially. The ZPD103KC, ZPD120KC, ZPD137-182KC and ZRD94-125KC digital scroll compressors employ a solenoid valve that is mounted on the side of the compressor that vents the intermediate cavity to the low side of the compressor during the unloaded state. During the loaded state the solenoid valv is de-
Application considerations :
Operating Envelope - Refer to the fixed capacity compressor model family application bulletin for approved operating range. System testing is highly recommended to verify adequate oil return during fully loaded and modulated operation.
Features :
- Two stages of capacity; either 67% or 100%
