2021-01-25 · The R744 E-Compressor is a prototype that is still under optimization development. It has a smaller displacement due to a larger volumetric cooling/heating capacity of CO2. The main features of the E-compressor are high discharge temperature (e.g., 150℃ or larger), high discharge pressure (e.g., 12.5 MPa or larger), power consumption (e.g., less than 6 kW), etc.

CO2 (R744) · Refrigerant grade R744 (CO2) is available from A‑Gas in gas ( vapour) or liquid form · Non-flammable with a safety classification of A1 · Compressors

Gen3 Electrical Compressor. Sanden International (Europe) GmbH Am Taubenbaum 35-37 Bad Nauheim, Germany, 61231 + 49 6032 8030 0 Company # HRB 113309. Sabroe high-pressure screw compressor units The unique Sabroe high-pressure compressor units are ideal for large site-built ammonia heat pump installations that condense at either 90°C or 72°C. They are also the ideal choice for larger CO 2 systems or low-temperature two-stage freezer installations, such as carbon dioxide-ammonia (R744-R717) cascade refrigeration systems.

Refrigerant flow and heat transfer have been optimized for best performance. All compressors are equipped with CoreSense™ technology and offer the possibility to Valeo Launches R744-Charged HVAC and Heat Pump Unit for E-Buses By Ilana Koegelenberg, Nov 11, 2019, 15:23 The small-scale roof-mounted reversible heat pump heats, cools and demists electric-vehicle cabins. 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.
