The ideal refrigerant can be selected considering certain factors like - favourable thermodynamic properties, non-corrosive nature and safety features like its toxicity and inflammability. It changes from a liquid to gas when it absorbs a room’s heat and then again gets back to its liquid form when the compressor compresses it.
A refrigerant has to undergo phase changes to absorb and compress the heat to distribute cold fresh air into the room. What is a refrigerant? A refrigerant or coolant used in air conditioners takes out the heat of a room and throws it outside into the atmosphere. Here we will discuss the various refrigerants that are used in air conditioners available in the Indian market. It is even the consumer’s responsibility to monitor whether their air conditioner is using environmentally friendly refrigerant or not, as most users presume that the CFCs have been phased out.
Later on, the manufacturers decided to phase out all the refrigerants that cause harm to the environment. Earlier, most refrigerants used to emit CFCs (or chlorofluorocarbons) which were involved in the depletion of the ozone layer. Consumers need to be aware of the coolants that are used in air conditioning systems as it will enable users to make informed decisions regarding maintenance, repair and updating of their home and office cooling systems. Modern air conditioning systems use different types of coolants that helps in bringing the room temperature down as the mercury rises outside.
