Total and Partial Heat Recovery Pressure Drops
To determinate the pressure drop for different versions or at different working condition, please refer to the following formula:
PD

(kPa) = PD
1
(kPa) x
1.80

Pressure drop to be determinated (kPa)
PD

Pressure drop at nominal condition (kPa)
Q

water fl ow at new working condition (l/s)
Q

water fl ow at nominal condition (l/s)
How to use the formula: Example
The unit EWWD360I-XS has been selected for working at the following conditions:
- evaporator water in/out: 12/7°C
- condenser water in/out: 30/35°C
- Partial heat recovery leaving wate
r temperature 45/50°C
The heating capacity at these working conditions is: 13.2 kW
The water fl ow at these working conditions is: 0.63 l/s
The unit EWWD360I-XS at nominal working conditions has the followi
ng data:
- evaporator water in/out: 12/7°C
- condenser water in/out: 30/35°C
- Partial heat recovery leaving water temperature 40/45°C
The heating capacity at these working conditions is: 23.8 kW
The water fl ow at these working conditions is: 1.14 l/s
The pressure drop at these working conditions is: 17 kPa
The pressure drop at the selected working condition will be:
PD
