Water system
Cooling water system guarantees Water Cooled VRF reliable operation. Water volume and water temperature
should reach the design index (see the technical parameter) during the designing of VRF water system in order
to not cause cooling volume dropping or tripping protection because of inadequate water or lack water or water
temperature too high.
① System water volume and water temperature
The total water flow volume is the sum of each Water Cooled VRF flow volume referring to technical specs. for
each individual unit rated water flow volume. Temperature of water inlet is 7-45°C. When system uses electrical two
way valve to control water flow volume, the total water flow volume can be counted by the units working ratio.

② Cooling towers and pumps
a) Select the cooling tower capacity based on the system's water circulation volume.
b) The unit water system must select the closed cooling tower.
c) Circulating Pump is generally vertical pipeline pump. It is according to the length of the pipe and drag to select a
pump head. To ensure system security, water pump should remain a standby pump.
