Daikin is the only air conditioning equipment manufacturer that also produces refrigerants.<\/p>\r\n\r\n\r\n\r\n
As recently as 2012, Daikin launched an air conditioner that uses the HFC-32 refrigerant, or simply R-32. The \u201cUrusara 7\u201d was the world\u2019s first split-type air conditioner developed with R-32 refrigerant.<\/p>\r\n\r\n\r\n\r\n
But what exactly is R-32?
It is a new class of refrigerant that has attracted great interest in the global industry due to its remarkable low environmental impact. R-32 is a pure HFC refrigerant, used in small air conditioners, and also as a component in HFC blends.<\/p>\r\n\r\n\r\n\r\n
Compared to current refrigerants like R-22 and R-410A, it has a low global warming potential (GWP) and no ozone depletion potential (ODP). R-32 is mildly flammable.<\/p>\r\n\r\n\r\n\r\n
We can note from the table below that R-32 offers only one-third of the GWP of R-410A, and nearly the same proportion compared to R-22.<\/p>\r\n\r\n\r\n\r\n
It is known that the thermodynamic and physical properties of a refrigerant directly influence the system and the compressor.<\/p>\r\n\r\n\r\n\r\n
Just to mention 2 of these properties:<\/p>\r\n\r\n\r\n\r\n
\u2013 The saturation pressure of R-32 is similar to that of R-410A, which facilitates the development of a system based on R-410A.<\/p>\r\n\r\n\r\n\r\n
\u2013 R-32 has a much lower density than R-410A, so the amount of refrigerant in the system (split) is smaller, and since GWP is measured in kilograms, the climate impact of R-32 in the system is even lower than suggested by its GWP.<\/p>\r\n\r\n\r\n\r\n
Why did Daikin choose R-32?
Daikin was the first company in the world to successfully use R-32 in air conditioners, leveraging its experience as the only manufacturer that also develops and produces refrigerant fluids.<\/p>\r\n\r\n\r\n\r\n
Before selecting R-32 for its air conditioners, Daikin analyzed several refrigerants and considered four criteria:<\/p>\r\n\r\n\r\n\r\n
Environmental impact: As mentioned above, R-32 has zero ODP and one-third of the GWP of refrigerants R22 and R410A.<\/p>\r\n\r\n\r\n\r\n
2. Energy efficiency: The efficiency of R-32 can be up to 1.5 times higher than that of R-410A or R-22. This potential is measured by a factor called \"Cooling Seasonal Performance Factor\" (CSPF). The peak energy consumption of R-32 is also lower.<\/p>\r\n\r\n\r\n\r\n
3. Safety and Flammability: According to ISO 817\/2014, R-32 is classified as having low flammability and low toxicity.<\/p>\r\n\r\n\r\n\r\n
4.Cost-effectiveness: To select economical and efficient refrigerants, certain questions need to be asked, and R-32 performed well in the test.<\/p>\r\n\r\n\r\n\r\n
\u2013 Is the refrigerant relatively inexpensive and easy to maintain?
\u2013 Does it contribute to reducing the overall operation and maintenance costs of the system?
\u2013 Is recycling feasible and relatively inexpensive?<\/p>\r\n\r\n\r\n\r\n
As you can see, R-32 was a well-chosen refrigerant by Daikin.<\/p>\r\n\r\n\r\n\r\n
And that's not all \u2014 besides manufacturing and selling R-32, Daikin provides technical assistance to governments and international organizations with the aim of training teams for the proper handling of R-32, among other ongoing activities.<\/p>\r\n\r\n\r\n\r\n
Well everyone, the topic is extensive and interesting. I think this gives a good idea of what\u2019s coming with R-32. We will return to discuss it in other articles.<\/p>","protected":false},"excerpt":{"rendered":"
