# The Ecodesign for Energy-Related Products and Energy Information Regulations 2021, Paragraph 5: Modelling parameters per compartment type for the calculation of SAE


(1) Table 18 sets out the modelling parameters per compartment type for the calculation of SAE.

(a) between 1.15 and 1.56 for combi appliances with 3- or 4-star compartments;
(b) 1.15 for other combi appliances;
(c) 1.00 for other refrigerating appliances.

(2) For the purposes of table 18—
(a) rc is (Ta-Tc)/20, where Ta = 24 °C and Tc is the determined value as set out in Table 17;
(b) C for combi appliances is determined as follows—
(i) frzf = Vfr/V, where—
(aa) Vfr is the 3- or 4-star compartment volume;
(bb) V is the total volume of the appliance;
(ii) if frzf ≤ 0.3, C = 1.3 + 0.87 × frzf;
(iii) if 0.3 < frzf < 0.7, C = 1.87 – 1.0275 × frzf;
(iv) in any other case, C = 1.15.
