operate in the required temperature ranges. CO2 air conditioning systems are designed to be energy-efficient and environmentally friendly. 4. Industrial Refrigeration: CO2 is being used in industrial refrigeration processes, such as those required for freezing and cooling in food processing and cold storage. It was also used in applications like ice rinks and thermal storage systems. 5. Transport Refrigeration: CO2 has been employed in transport refrigeration units, including refrigerated trucks and trailers. These units use CO2 as a refrigerant to keep perishable goods at the desired temperatures during transport. 6. Beverage Dispensing: CO2 has long been used in the beverage industry to dispense carbonated drinks like soda and beer. It plays a crucial role in maintaining carbonation and serving beverages at the right temperature. 7. Water Heating: In some innovative water heating systems, CO2 was used as a heat transfer fluid to provide hot water for domestic and commercial purposes.

CO2 AS A REFRIGERANT

CO2 is being used in the refrigeration industry in various applications due to its environmentally friendly properties, low global warming potential (GWP), and ozone depletion potential (ODP). Here are some common ways in which CO2 was being utilized in refrigeration: 1. Commercial Refrigeration: CO2 is being used in large commercial refrigeration systems, especially in supermarkets and cold storage facilities. These systems are designed to maintain low-temperature conditions and keep food products fresh. CO2, often in a transcritical cycle, was used as a natural refrigerant to replace traditional synthetic refrigerants with higher GWP. 2. Heat Pumps: CO2 heat pumps were employed for both heating and cooling purposes in residential, commercial, and industrial settings. These heat pumps could efficiently provide space heating and cooling while reducing energy consumption and environmental impact. 3. Air Conditioning: In some applications, CO2 is being used in air conditioning systems, particularly in regions where it can effectively
