The properties of R744 affect how the refrigerant is applied (see post 3 of this series for more details): The high density of R744 compared to hydrofluorocarbons (HFCs) results in the requirement for less compressor displacement, typically 1/5th of that needed for R404A.

R744 (CO2) is becoming increasingly popular due to its excellent properties. With an Ozone Depleting Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1, R744 (CO2) is a natural refrigerant. R744 Compressor development ixetic is confident that the design concept of the swash ring compressor is competitive. And the results so far are more than promising: test data proves that the characteristics critical to R744 compressors, such as leakage rate, volumetric efficiency and initial starting will be robust during production, and can be monitored online.

Provides information on CO2 technology for heating, cooling and refrigeration. Includes news, products, jobs, events, knowledge, forum, blog and a worldwide directory of partner companies. •The low stage compressor would operate at low capacity (<30%) and hence low efficiency, for more than 82% of the time Therefore in the interests of achieving highest possible plant efficiency, it was decided to select dedicated CO 2 (R744) condensing units with direct expansion fan coil units Designed For Durability And Best-In-Class Performance Technical Specifications The Stream line of 4 cylinder R744 compressors is the ideal solution for R744 medium temperature cascade and booster systems. It is characterised by a design pressure of 135 bar.

The R744 compressor has a 31cc capacity, a fifth of the PX R134a unit it replaces, but Sanden claims its “cooling performance and function exceeds conventional compressors”. Its packaging and weight is also said to match that of the PX R134a compressor and it is able to withstand five times the operating pressure. Global manufacturer Danfoss has added its CO2 compressor, valves, pressure controls, controllers and sensors for small commercial applications to R744.com.

Stream CO2-Verdichter haben einen Auslegungsdruck von 135 bar.Kältemittelfluss und Wärmeaustausch wurden für höchste Leistung optimiert. This example models a vapor-compression refrigeration cycle in which the high pressure portion of the cycle operates in the supercritical fluid region. The refrigerant is carbon dioxide (CO2), also called R744 in this application. The compressor drives the flow of CO2 through the cycle and raises the pressure above the critical pressure.
