The world is currently facing two serious environmental issues, ozone layer depletion and global warming. One of the major contributory factors in the air conditioning industry is the refrigerant gas used in the equipment. In the past, each generation of refrigerants was considered to be the optimum one to use.

With the Montreal Protocol implemented by as many as 200 countries now, harmful chloro-flouro carbon (CFC) and hydro-chloro-flouro carbon (HCFC) refrigerants are being replaced with new alternatives, which are less harmful to the environment. Such refrigerants qualify as they have zero ozone depletion potential (ODP) and low global warming potential (GWP) while maintaining high system energy efficiency.

One of the questions before India in its implementation of Montreal Protocol commitments is the need to align its goals for Make in India with green technologies in order to remain competitive in global markets. Inducting alternatives to HFCs, such as hydrocarbons, ammonia and carbon dioxide, in the relevant industries should happen sooner than anticipated and possibly become even attractive as the cost of technologies falls. The changeover is actually an opportunity to achieve a leapfrog effect.

With the Kigali Amendment in place, the emission of carbon dioxide into the atmosphere is sure to be reduced. To this end, there is a diversity of refrigerants that can be used for specific applications. What should be the ideal/dream refrigerant be? It should be a safe compound (or blend of compounds) with no toxicity or zero flammability risk. It should have no compatibility problems with materials of construction, be inexpensive to produce, and provide a capacity greater than the existing R-22 and R-410A refrigerants. To be absolutely perfect, it should be available as a drop-in refrigerant that operates more efficiently than current refrigerants do in existing systems.

Each refrigerant has a GWP with carbon used as the base. Carbon has a GWP of 1. R-410A has a GWP of 2088, so if 1kg is released into the atmosphere it will have 2088 times the harmful effect of one kilogram of carbon. R-22 – a hydro chlorofluorocarbon (HCFC) – has a GWP of 1810. Hence, R-32 (difluoromethane) has emerged as a viable alternative for air conditioning applications. It has zero ODP and low GWP of 675 (modified = 473) over the 100-year duration period by which refrigerants are rated.

At Daikin, the future of the world’s air is of great concern. The company is constantly paving the path to save the environment. The manufacturer has phased out all its R-22 models and shifted to the green refrigerant, R-32. The brand has sold over 10 million units in 52 countries since its introduction. The company introduced its first R32 unit in Japan in 2012. Units with R-32 were introduced in India in March 2013 and Europe later the same year. Australia and Thailand followed in 2014. India and Thailand have become the countries with the largest number of R-32 air conditioners sold outside of Japan. Now, the whole world is coming together to find and work on ways to address the global warming issue.

The FTKP series by Daikin is a popular inverter air conditioner series that follows the legacy of green cooling and features the R-32 refrigerant. The series also offers Coanda airflow, in which the louvers of the air conditioners open upward and give a pleasant air conditioning in the room. It is equipped with the PM 2.5 filter, making the air in the room cleaner and fresher. The power chill operation quickly maximizes the cooling effect in any operation mode. The company also offers worldwide free access to patents for equipment using the next generation refrigerant, R-32, showcasing Daikin’s commitment to, and unrivalled expertise in, the use of R-32.

Daikin remains committed to promote the spread of low GWP refrigerants while encouraging the exploration and development of refrigerants and air conditioning equipment with lower environmental impact.
