3. Sizing

3.1 Input data required for sizing

In order to design a device adapted to the needs of the site, with controlled purchase and operating costs, you need to know :

the hourly quantity of heat to be removed Q (J/h) ;
cooling water flow rate q _vr (m ³ /h) ;
the temperature drop of this water ΔT = T _e2 – T _e1 (K) ;

knowing that these three data are linked by the following relationship :
$Q = 4,18 \times 10^{6} q_{v r} Δ T$
