The performance of the chillers can be represented by the Daily
AVG COP, either the Daily AVG COP 07:00–18:00 or the Daily AVG
COP 19:00–23:00, depending on which portion of the energy demand
is being shifted. As an example, when addressing the first area of
intervention, shifting the energy to avoid partial load operations (red
area, Fig. 4), the average COP considered is the Daily AVG COP
19:00–23:00.
The Annual electricity savings (kWhe/year) are calculated as the
difference between the Daily electricity consumption of the cooling
system before and after the CTES introduction, multiplied by the
Number of Operative Days per Year (NODY).
