R744 is the refrigerant name for carbon dioxide, which will first appear in high-end cars from the big German brands. CO2 requires operating pressures up to ten times higher than R134a.

Furthermore, corrugated stainless steel hoses are required downstream of the compressor on the hot gas line. When using R744 refrigerant, two particular aspects must be considered for reasons of operational safety: co2 – r744 Home / Products / CO2 – R744 By using the environmentally friendly refrigerant CO2 with a GWP of 1, all cooling requirements can be met safely, efficiently and in compliance with all the applicable standards and laws.

R744. ASHRAE-klass.

Its ODP is zero and its GWP is as low Amoniaco, CO2 = ODP nulo, GWP nulo o despreciable Dióxido de carbono, CO2 (R744): es un fluido natural, OPD nulo, GWP=1, y sin las contraindicaciones R744 is a high purity carbon dioxide (CO2) based refrigerant gas with a typical moisture content less than 10 parts per million. The low moisture content enables CO2 (R744) Evaporators. CO2 Evaporators are specially designed for cold room and frozen storage room applications which are working with subcritic and 4 Sep 2020 Application Note: Pressure Sensors in CO2 (R744) HVAC/R Applications. Applying pressure sensors that can withstand high pressures, are The refrigerant is carbon dioxide (CO2), also called R744 in this application.
