R744 (Carbon dioxide) R744 (Carbon dioxide) R744 is environmentally friendly, having zero ODP (Ozone Depletion Potential) and minimal GWP (Global Warming Potential). R-744 Carbon Dioxide is one of the oldest refrigerants in the world. Its first usage can be traced all the way back to the nineteenth century. Before the popularity of CFC and HCFC refrigerants Carbon Dioxide was one of the most widely used refrigerants. The h-s Diagram for Carbon Dioxide (R744) A Heat Pump System using Carbon Dioxide Refrigerant (R744) In addition to being a environmentally benign fluid, there can be significant advantages to using carbon dioxide in a home air-conditioning/heat-pump system environment.

Tillämpning av CO2 (R744) Köld i industriell Cold Storage kylanläggning kylcykeln som använder CO2 som arbetsvätska som är sammansatt med gaskylare, Motorn dricker gas, slukar luft och skar ut en kontinuerlig ström av När det CO2-baserade kylmediet, kallad R744 släpps ut i atmosfären, diskussionen om det reviderade F-gas direktivet hade inte riktigt startat.

The term R744 refers to CO 2 when it is used as natural refrigerant in the refrigeration and air conditioning industry. R744 CO 2 has excellent thermodynamic properties and has significant advantages compared to classical and other alternative refrigerants: R744 refrigerant properties: The new station therefore conforms to the strictest industry standards governing air conditioning maintenance and recharge systems for the new R744 (CO2) refrigerant. These new systems are intended to minimise pollution and to reduce the risk of fire in the event of leaks, and are radically different in design from previous generations of recharge station that used R134a and R1234yf refrigerants.

The evaporator pressure is at kept at around 3.5 MPa and the gas cooler pressure is nominally around 10 MPa, which is above the CO2 (R744) critical pressure of 7.4 MPa. Hence, this is a transcritical refrigeration cycle. The gas cooler pressure changes in response to changing environment temperature.

solid R744 sublimes directly to a gas. Solid R744 will have a surface temperature of -78°C. If R744 is at a pressure higher than the triple point and it reduces to a pressure below the triple point (for example to atmospheric pressure), it will deposit directly to solid.
