/h)

Dt: difference between inlet and outlet water temp. (°C)

P: heat exchanger capacity (kW)

Pressure drop is given by:

Dp= K x Q

/1000

Q: water flow (m

3

/h)

Dp: pressure drop (kPa)

K: unit size ratio

K evap:   standard mains filter included

Q min:   minimum water flow admitted to the heat exchanger.

Q max:   maximum water flow admitted to the heat exchang-

er.

W.c min.: minimum water content admitted in the plant, using
