134-I series is the screw compressor unit specialized for R134a refrigerant with an inverter to regulate energy as a complete new design of RefComp.

The compressor unit mainly features integrated arrangement of inverter and compressor and cooling of inverter by refrigerant (RefComp patent) with compact structure and easy and reliable application.

Compared with the existing R134a conventional compressors, the compressor boasts higher actual operation efficiency and stronger application applicability with frequency range of 30 Hz - 70 Hz which can be adjusted to 15 Hz - 80 Hz after consulting RefComp.
Uniquely innovative technology of automatic regulation of compression ratio (RefComp patent) guarantees best efficiency of compressor within large operating range and under variable working condition to the maximum extent, and further enhances annual overall efficiency substantially on the basis of variable frequency regulation.

Besides, the technology marks more remarkable advantages for chiller units, various water-source/ground-source heat pump unit and ice storage unit.
