Directives vanuit Brussel

Drivers om gebruik te maken EED directive: Energy Efficiency Directive van • Member states have to set targets and implement (omkeerbare) strategies to assure 20% targets • Requiring long term policy (2050) for total building stock • Reduce energy sales to final users by 1.5% per year warmtepompen (2012/27/EU)

• • •

Authorities refurbish min 3% per year Improve efficiency of power and heat generation More smart grids & meters

Typical refrigerants used today stationary air conditioning & heat pumps

R410A : GWP2088 R407C : GWP1774 R290 : GWP3

R410A : GWP2088 R410A : GWP2088 R134a : GWP1430 Cooling and Heating capacities range from <1 kW to > 10,000 kW

Revised F gas regulation : GWP limits for air conditioners & heat pumps Ban on HFC with GWP150 from 2020

For SINGLE split air conditioners with a charge BELOW 3 kg : Ban on HFC with GWP750 from 2025 No GWP limit for Chillers (unless Chiller is used for refrigeration applications where GWP 2500 is not allowed)

No GWP limit for charges > 3kg No GWP limit for multi split or VRF All HFCs used in the equipment will be subject to the HFC “phase down”, even if there is no specific ban or GWP limit.

“No GWP limit” is NOT equal to “business as usual” !

Revised F gas regulation : HFC “phase down” targets Reduction on the placing on EU market of HFCs – in CO2 equivalent = quantity x GWP

How to achieve this HFC phase down ?

Where possible : 1) Change to HFC refrigerants with a lower GWP 2) Change to non-HFC refrigerants 3) Reduce the HFC refrigerant quantity 4) Recover and reuse HFCs 5) Any combination of 1) 3) 4)

GWP comparison of R410A & R32 Quantity

GWP x Quantity

> 75% Reduction â&#x20AC;˘ The GWP of R32 is only 1/3rd of R410A GWP Values according to IPCC 4th Assessment Report For the EU F gas regulation the GWP values of IPCC 3rd report are valid (R410A = 1975, R32 = 650)

â&#x20AC;˘ Taking into account the refrigerant charge, the GWP is only 1/4th !

Impact on installation / service â&#x20AC;˘ Technically, installation of i.e. R32 unit is the same as R410A â&#x20AC;˘ Tools are slightly different Tooling

Flammability of 2L refrigerants is very low.

The burning velocity (â&#x2030;¤ 10 cm/s) is too slow to cause horizontal flame propagation or explosion.

Classification according to ASHRAE34 & ISO817.

There is no “one-size-fits all” refrigerant • Each manufacturer needs to make choices depending on the application and the needs of the market & taking into account local legislations & standards.

• R32, HFO’s expected to become main refrigerants, next to number of naturals in specific segments like refrigeration

R32

i.e. R410A will still be needed for those applications where the use of flammable refrigerants is restricted.
