Water volume flow m˙ w [kg/h]
Formula 1
Calculating the average temperature difference ∆m
tW1 [°C] + tW2 [°C]
∆m[K] = tR -
2
Formula 3
Calculating the total cooling capacity Q˙ Ktot (1 unit)
Q · K(tot)[kW] = q ˙K(specif)[W/m] · L(finned)[m]
Formula 4
Estimating roughly the water volume flow m˙ w
q˙ (spezif) [kW/m] · L(finned)[m]
m˙ W[kg/h] = 860 ·
tW2 - tW1 [K]
Formula 5
Calculating the total water-sided pressure drop (1 unit)
∆pW(tot)[kPa] = ∆qW(specif)[W/m] · L(finned)[m]
∆m[K] = Average temperature difference between two different media
tR [°C] = Room temperature
tW1 [°C] = Water inlet temperature
tW2 [°C] = Water outlet temperature
m · W[kg/h] = Water volume flow
Q · K(tot) = Total cooling capacity of a hilled beam
q · K(spezif)[W/m] = Cooling power per metre of finned chilled beam length (L(finned))
(L(finned)) [m] = L(tot)[m] - 0,2 m
∆pW(tot)[kPa] = Total pressure drop of a chilled beam
∆pW(spezif)[kPa/m] = Specific pressure drop of 1 m finned chilled beam length (L(finned)) see Fig. 20.5
