Introduction

This guide describes the use of BITZER refrigerant ejectors in R744 systems and contains information and advice on transcritical applications and capacity control.

It is constantly developed and will in future cover the basics and special features of CO₂ applications for commercial and industrial refrigeration as well as heat pumps. As the individual topics are added successively, this guide does not claim to be complete at the moment.

Several information and notes in this technical information, such as compressor design, application limits and oil types used, refer to BITZER products, and cannot always be completely generalized.
