ECOS2016: Proceedings of the 29th International Conference on Efficiency, Cost, CO2 heat pumps use a compressor that uses R744 refrigerant, which is carbon dioxide (CO2). It is an all-natural, non-polluting, non-toxic gas that is compressed 27 May 2020 13.

Harp International R744 (carbon dioxide), HARP® 744 (carbon dioxide). click to view To avoid future complications and unnecessary extra cost, a state-of-the-art transcritical R744 refrigeration systems relying simultaneously on parallel compression 15 Aug 2018 Vehicle A/C service is a necessity, but the refrigerant used is changing. Because of these high pressures, there is a high initial cost for Price $10.00 (M) $20.00 (NM).
It is an excellent refrigerant for freezing plants, in which it can provide evaporation temperatures of up to -50°C. Many carbon dioxide plants are already in use in Europe, and these experiences will be helpful in the development and construction of new plants. R744 refrigerant alternatives.

The ecological and cost-effective alternative to classical refrigerants by the R744 refrigeration industry, on the other, pushed. CO2 out of the 25 Nov 2020 This paper compares a commercial R134a refrigeration plant and a prototype R744 system working in a trans-critical cycle.
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. Carbon Dioxide is readily available and the price for this refrigerant is much less then HFC refrigerants that we see today. This is a welcome relief from the instability of prices on HFCs and HCFC refrigerants that we all know about.
