SERVICE SIDE - WITH HYDRONIC KIT AA-AJ - BA-BJ (HEAT EXC PIPES + WATER ACCUMULATION)
The water flow rate is calculated with the following formula:
Q = Pc x 860 / ΔT
Q
Water flow rate (l/h)
Pc
Cooling capacity (kW)
ΔT
Water heat drop (°C)
Pressure drops are calculated with the following formula:
Δp = K x (Q)2
Δp
Pressure drops (kPa)
Coefficient
for the various sizes and versions
