R152a also entails a good reduction, equal to 53.6%. The above mentioned values can be observed in Figure 4.10. R1234ze(E) R1234yf R1270 R290 R152a R32 -60.00% -50.00% -40.00% -30.00% -20.00% -10.00% 0.00% Figure 4.10. Relative difference (%) of TEWI compared to R410A (radiator heating) In the case of floor heating the results can be seen in Figure 4.11. The pattern already observed in the radiator heating case is respected in this case already. Due to the overall higher SCOP values, the TEWI is generally lower thanks to a lower indirect effect. The direct effect is of course unchanged. Every refrigerant obtains a TEWI round 5-6% lower. The outcome can be seen in Figure 4.12. 5000.00 4500.00 4000.00 3500.00 3000.00 2500.00 2000.00 1500.00 1000.00 500.00 0.00 156.24 R152a 2.07 5.13 R290 R1270 6.38 11.27 2881.44 1784.82 914.09 1671.61 1786.42 1908.15 1934.78 Direct effect Indirect effect 1929.34 1844.74 R410A R32 R1234yf R1234ze(E) Figure 4.11.
