Scroll Compressor
The scroll compressor features a digital port and an intermediate suction port.
Digital Port
The digital port provides cooling capacity control. The digital port is located at the top of the scroll
assembly on the compressor body. When energized, the Digital Control valve disengages the scroll set.
This reduces pumping capacity to zero.
Intermediate Suction Port
The intermediate suction port draws suction gas from the economizer heat exchanger into the scroll
assembly of the compressor. The scroll seals off the suction port. This prevents economizer gas from
leaking back to the main suction port. It also prevents the economizer gas pressure from influencing the
cooling capacity of the unit evaporator (main suction gas pressure).
