Koura submits CO2 alternative for ASHRAE approval


Uk: The strange component mix of a new non-flammable refrigerant from Koura, which it statements has a decrease environmental impression and much better performance than CO2, have now been unveiled.

Initially announced past calendar year and dubbed LFR3, Koura promises the new refrigerant will be ideal for a range of cooling applications like mobile air conditioning, heat pump systems, cold chain and transportation refrigeration and professional refrigeration.

The refrigerant, which said to be up to 20% much more power successful than CO2 with 15-20% reduce operating stress, has now been submitted to ASHRAE for designation and protection classification.

The new fuel is, alone, 69% CO2 with the addition of 21% R32 and 10% R1132a. In accordance to Koura, the mixture helps make LFR3 non-flammable – the CO2 suppressing the flammability of the other two components. These mix proportions also give LFR3 a GWP of 143 underneath AR4, tucking it neatly less than the 150 GWP refrigerant restrict now in position in Europe for certain purposes.

A GWP of less than 150 is expected below the MAC polices for car air conditioning units and, since January 1, the European F-gasoline regulations have placed the same limit on new hermetically-sealed business refrigerators and freezers and multipack centralised industrial refrigeration devices with a rated capacity of 40kW or a lot more. The US Environmental Security Company is also mentioned to be looking at a related nationwide regulation that might just take effect in 2024.

The R1132a molecule capabilities in a variety of other new Koura developments including R473A, its not too long ago released minimal GWP alternate to R23 in ultra reduced temperature purposes.
