inorder to make the water flow rate in each exchanger maintain the same,
and to avoid bias current phenomena, try to make the shuttle water pipe
resistance from chiller to every heat exchanger all the same.
4) Adopts sealed loop water system to buffer the water volume expansion or
shrink phenomina and insulate the backup water pressure to water pipe's
impact. Mount expansion water tank at unit's water returning place. The water
level of the expansion water tank should be at least 1 m higher than the top of
the waterpipe.
5) The cooling pump of the chiller should be installed at the inlet of the
evaporator.
6) Inorder to avoid the air remains in waterpipe system, the higher point of the
water pipe should have auto air vent valve mounted on. And the horizontal
water pipe should be constructed upward in 1/250 slope angle. Derusting
before water pipe installation. Make it clean and no slag.
7) Install anti-vibration soft pipe at the water pipe outlet to prevent the unit's
vibration from getting into indoor via pipes.
8) Install thermometer and pressure gauge at the inlet and outlet of the unit to
facilitate the daily maintenance.
9) When the chiller is in operation, the water flow rate and antifreeze flow rate
within evaporator should remain above the minimal.
10) Install coupling base with the water inlet/outlet pipe accessories which can
easily separate itself with waterpipe when checking.
11) The weight of the pipe should not be supported by unit
,
the inlet/outlet of the
pump group should separate itself with respective water pipe by a
anti-vibration pipe or a rubber joint to avoid vibration and noise transmission
or interfering.
12) Install water pipes for chiller, condenser or cooling water as the following
