Note: All of water pipe accessories and flow switch is provide by user.
Users must install flow switch in the outlet pipe of cooler and evaporator, the two sides must be level straight pipe
with a length longer than five times the pipe diameter.
3) The water inlet pipeline and drain pipeline must be connected according to the requirements of
markings on the unit. Generally, the refrigerant pipe side of the evaporator is the chilled water
outlet side.
4) The chilled water pipeline system must be provided with the soft connection, thermometer,
pressure gauge, water filter, electronic scale remover, check valve, target flow controller,
discharge valve, drain valve, stop valve, expansion tank, etc.
5) The water system must be fitted with the water pump with appropriate displacement and head to
ensure normal water supply to the unit. The soft connection must be used between the water
pump, unit and water system pipelines, and the bracket must be provided to avoid stress on the
unit. Welding work for installation must avoid damage to the unit.
(1) Determination of water pump flow:
Flow (m
3
/h) = (1.1 ~ 1.2) * Unit Cooling Capacity (kW)/5.8
(2) Determination of water pump head:
Head (m) = (Unit Resistance (see product parameters) + Resistance at Maximum End of
Pressure Drop (see product parameters) + Pipeline Resistance (length of the least favorable loop
pipe * 0.05) + Local Resistance (length of the least favorable loop pipe * 0.05 * 0.5)) * (1.1 ~ 1.2)
