For some applications, the current threshold to introduce R744 technology can be overcome when the system design takes into account the advantage of the thermo dynamical- and fluid properties of CO2. I.e. Modular Cascade R134a / R744 The newly developed Cascade solution by BITZER Australia provides the combination of low side R744 /CO2 and R134a high side systems into the one compact unit. This provides contractors and end users a robust construction with compact dimensions. Utilising the new SL series R744 compressors for R744: Masstores has recently implemented the use of CO 2 refrigeration in its new Makro store builds. What was the driving force behind the implementation of CO2 technology? Masstores has always been acutely aware of the long-term damage caused by HFC/HCFC use. 2015-07-30 · This is post number seven of a series.

Carrier presents NaturaLINETM CO2 container refrigeration technology Posted on December 17, 2010 by r744 Carrier Transicold has announced the world’s first natural refrigerant technology for container refrigeration that takes advantage of a new marine-duty multi-stage CO 2 compressor.

Köldmedieventil MVL661..-.. kan användas med de flesta köldmedierna (R22, R134a, R227ea, R404A, R407C, R410A osv.) samt R744 (CO2). Upplagt: 1 vecka sedan.

R744 (Dioxyde de carbone) Le R744, ou dioxyde de carbone, fait une nouvelle apparition dans le monde de la réfrigération industrielle. Alors qu’on a déjà cru qu’il s’agissait d’une matière inefficace qui demandait trop de pression pour être employée comme agent réfrigérant, les environnementalistes acclament maintenant le R744 comme une réponse à des préoccupations croissantes.

In a transcritical cycle, the CO2 supercritical fluid is between gas and liquid, and has the dual characteristics of gas and liquid. An overview Transcritical CO2 technology has been deployed in a variety of applications across the world for many years. Elimination of any future phase-outs by using R744 (CO2), CO2 as a natural refrigerant, also known as R744, is the climate-friendly alternative to today's common chemical refrigerants. It is environmentally friendly, has a high cooling capacity, is not flammable and does not form any decomposition products. Furthermore, it is inexpensive and permanently available.
