9.5.1 3-way-cooling water control valve

The 3-way cooling water control valve is controlled by the InRoom relating to the condenser pressure by

means of a pressure sensor at the refrigerant side. This valve controls the distribution of the water ﬂ ow

through the condenser and the bypass.

9.5.2 2-way-cooling water control valve

The 2-way cooling water control valve is controlled by the InRoom relating to the condenser pressure by

means of a pressure sensor at the refrigerant side. This valve controls the water ﬂ ow through the conden-

ser. In the table below, the admissible maximum differential pressures are listed per valve size. Up to these

pressures the valve is kept closed safely. (Closing pressure).

The admissible maximum differential pressure, at which the valve can control the water ﬂ ow throughout the

whole range, is 2 bar for all valve sizes.
