3.5 Water System Tubing
1) The inlet /outlet pipes and valves of the unit should have itselves insulated.
The outside parts should have protective veil to prevent the thermo lost and
dewfall happen and this brings no impact on building structure and
anti-freezing when it is in winter.
2) To ensure that there is enough water in the water-side exchanger and
pipeline system so to avoid its internal icy water comes to freeze up, over low
pressure and bad oil return rate within system when refrigerating
，
there after
lead to the failure of the compressor and burn down to the worse. So water
flow switch should be mounted at the water outlet side and was controlled
chainly with compressor.
3) If closed circuit type water distribution pipelines are used, an inflated water
tank should be placed higher by at least 1m than top of the whole set of water
distribution pipelines to buffer the water volume's expansion or contraction
and the isolated backup water pressure to water distribution pipelines'
influence. Check valve should not be mounted at the outlet of inflated water
tank so to avoid pipe leakage or crack.
4) The pump of the unit should be mounted at the water inlet of the main module
machine.
5) Avoid air left in the water system, Install automatic exhaust steam
dischanging valve in the highest position of all the water distribution pipes.
The horizontal pipe of the water distribution system must be laid with an
inclination of 1/250.
6) There should have flexible joint, flange joint and break valve for later
maintenance.
7) There mameter and pressure meter should be set in the inlet and outlet of the
unit to facilitate daily check.
8) There are same directions way and opposite direction way to install the water
pipe of the module unit.
