Screw compressor refrigeration. Using Oil-Flooded Screw Compressors for Industrial Refrigeration

The benefits of using an oil-flooded screw compressor for industrial refrigeration are the focus of this article. Related posts. This has revolutionised designs of refrigeration and gas handling plants worldwide. Rotary twin screw compressor technology was developed in the s by a Swedish company, SRM, in collaboration with Howden. The compressor has been lauded for its high specific output, which is crowned by the usually small size of the devices.

 

First stage: the inlet port of the compressor takes the refrigerant. · Second stage: tooth space reduces as the seal line goes in the direction of discharge.Willis Carrier invented the modern-day air conditioner.

 

Designed with a special focus on energy-efficiency, GEA screw compressors are well-suited for industrial refrigeration and air conditioning.This port allows introduction of refrigerant vapor at an intermediate pressure between suction and discharge, which, in turn, allows for the use of an economizer.

 

Oil-flooded screw compressors are suited for use with numerous natural refrigerants, including ammonia (R), carbon dioxide (CO2) and.Likewise, centrifugal compressors are also limited on how much they can unload, and care must be taken to avoid surge at lower load conditions.
