Jan 23, 2024 · Compared to hydrofluorocarbon (HFC) refrigerants, the high density and volumetric capacity of R-744 impact the requirement for less compressor displacement, typically ⅕ of that needed for R-404A. However, the motor size is similar, since the work requirement is approximately the same.

The Emerson Copeland Stream series of 4 cylinder CO 2 compressors is the ideal solution for R744 booster systems. It is characterized by a design pressure of 135 bar. Refrigerant flow and heat transfer have been optimized for best performance.

These application guidelines cover Copeland™ scroll fixed- and variable-speed compressor models ZO(V)*AG using CO 2 (R744). These compressors have a speed range of 1500 to 6000 revolutions per minute, corresponding to 25 to 100 revolutions per seconds (1/s). They are intended for use in refrigeration applications.

The optimized design of ZO compressors effectively address the challenges of R744 systems i.e., high pressure levels, higher mass flow for a given displacement while securing proper lubrication.

The transcritical ECOLINE Series combines high efficiency, smooth running, a wide range of applications, solid design, high reliability in combination with the natural refrigerant CO₂. *For further documentation please choose Product Type.
