several air conditioner manufacturers in India were starting to introduce models that use eco-friendly refrigerants like R290 (propane) and R600a (isobutane). These refrigerants are considered more environmentally friendly compared to traditional hydrofluorocarbon (HFC) refrigerants like R410A.
Major brands such as Godrej, Daikin, Panasonic, LG, and Voltas have been among the pioneers in introducing air conditioners that use R290 or R600a refrigerants in India. However, please note that the availability of specific models may vary over time, as manufacturers continually update their product lines and technologies.
To identify air conditioner models that use R290 or R600a refrigerants, you can check the product specifications and labels provided by the manufacturers. Often, eco-friendly refrigerants are highlighted as a selling point in marketing materials, and the refrigerant type should be listed in the technical specifications of the product.
If you're interested in purchasing an eco-friendly air conditioner, I recommend checking with the official websites or contacting the customer support of these brands to inquire about the latest models and their refrigerant options as of 2023.
