As a natural working medium, CO2 is a key research orientation of chlorofluoro carbons (CFCs). In this article, we will cover the basics about CO2 refrigeration compressors, the differences between a CO2 compressor and other types of compressors, …

2024年1月23日 · Table 1 outlines the advantages and disadvantages of R-744 as a refrigerant. Although the list of disadvantages appears smaller than the advantages, these considerations should not be overlooked, as they have a significant impact on the safety and reliability of …

2022年5月9日 · Using carbon dioxide (CO 2) as a refrigerant began in early industrial times and has been revived in the past couple of decades. But what is CO 2 refrigeration? And why is CO 2 a good thing when it comes to refrigeration?

CO 2 is a natural cooling agent that delivers sustainable and energy-efficient refrigeration in everything from warehouses to ice machines. Allowing businesses to move forward naturally.

2024年1月23日 · R-744 is a byproduct of the industrial manufacture process during the production of ammonia, alcohol and fertilizer. The gas is captured, purified and compressed in a multi-step process — and finally liquefied for use as a refrigerant.

2024年1月23日 · In its processed state as a refrigerant (R-744), its thermophysical characteristics differ greatly from traditional refrigerants. Namely, R-744 has a higher triple point and lower critical point than hydrofluorocarbon (HFC) refrigerants. Figure 1 demonstrates the occurrence of CO 2 ’s triple and critical points on a phase change diagram.

2022年9月28日 · With a global warming potential (GWP) of 1 and zero ozone depletion potential (ODP), CO 2 is one of several emerging refrigerants capable of enabling food retailers to meet their sustainability goals and comply with environmental regulations.

2024年1月23日 · In post six of our CO2 as a Refrigerant blog series, I will compare CO 2 to traditional and emerging refrigerants. CO 2 has been an approved refrigerant in the U.S. for nearly a decade.

2024年7月30日 · CO2 is a natural refrigerant with a GWP of 1, which is significantly lower than that of HFCs and HFOs. It has zero ODP, making it an environmentally friendly option. The use of CO2 helps in reducing the overall carbon footprint of refrigeration systems, aligning with global sustainability goals.

warming. Examples of natural refrigerants in-clude carbon dioxide (CO2), hydrocarbons (such as propane and isobutane), and ammonia. The usage of natural refrigerants has gained momentum in recent years, driven by increas-ing awareness of climate change and the need for sustainable solutions. A majority of research
