CHHP N2 Trane Screw Compressor

The compressor motor is contained within the shell. It is protected from heat, corrosion, and dirt, a clear advantage over open drive machines. There’s no need for a driveshaft seal, so
refrigerant containment is complete.

Your current compressor may need replacement if:
  • The existing compressor is damaged from operating under extreme conditions for extended periods of time
  • The compressor has become damaged from fire, freeze-up, or other physical damage, or
  • The chiller has high operating hours, and a compressor replacement has been suggested.
  • Oil analysis results not satisfying
  • Vibration analysis results not satisfying

The GP2 Type CHHP compressor is a “screw” or helical rotor design with two rotors, one directly driven by the motor called the male and the other driven by the lobes of the male called the female.

The Trane GP2 CHHP compressors have a female step load solenoid valve and male load/unload solenoid valves that utilizes for capacity control. And the name of the step load solenoid is “female” Solenoid Valve. Because it acts on the female rotor side of the compressor, and its function is to “pilot” a larger valve inside the compressor that opens to bypass compressed vapor back to the suction of the compressor. This bypass action causes a “step” difference in the capacity of the compressor.

On the Male rotor side of the compressor is the male port unloader piston, which can move laterally along the male rotor. Small bypass ports in the rotor housing are covered and uncovered by the unloader piston as it moves. The position of the piston, controls by two direct acting solenoid valves called the male load and male unload solenoid valves. These valves add or vent pressure to the cylinder of the movable piston to position and “modulate” the amount of compressed vapor that bypasses back to suction.
