●The pipe pressure and flow rate should be calculated before selecting the diameter of the pipe,
pressure drop range is 0.3〜0.5 kgf/cm2(3〜5m"head pipe flow rate range is 1 .2〜2. 5 m/s.
●The hydraulic calculation should be made after selecting the pipe diameter. If the resistance is more
than the pump head, then a more powerful pump or larger pipes are required.
5.2.4 Required Water Quality
● Bad quality water will produce more lime scale and sand: this kind of water should be filtered and
demineralized.
●The water quality should be analyzed before operating the unit: PH value, conductivity, Chloride ion
concentration and sulphate ion concentration should be checked.
●Acceptable water quality shown below:
● Suggested filter mesh = 40.
6.1 Selection of the water pump
●The circulation pump is required for the system to operate, there is a terminal connection for the
pump (single phase)
NOTE For single-phase pumps, please check the wiring diagram.
●Head of circulation pump = height difference between water level and main unit + total pipeline
resistance (determined by the hydraulic calculation) + pressure loss of main unit (see nameplate on
heat pump).
NOTE Multiple units are installed in parallel place more demand on the water pump
requirement.
