The result graph (figure 3) shows that paraffins amortize after ~150 to 260 cycles and 100 to 160 cycles when replacing energy from the assumed reference systems with renewable cold or heat, respectively. Assuming a useful lifetime of 20 years this means a minimum of 7.5 to 13 and 5 to 8 cycles per year, respectively.
