  • Page 55 Hydraulic Module Integrated 3.7 Brazing Care must be taken to prevent oxide forming on the inside of copper piping during brazing. The presence of oxide in a refrigerant system adversely affects the operation of valves and compressors, potentially leading to low efficiency or even compressor failure.

Figure 3-3.7: Piping orientation during brazing Brazing Brazing Brazing Piping overlap during brazing Table 3-3.5 specifies the minimum permissible piping overlap and the range of permissible gap sizes for brazed joints on piping of different diameters.
  • Page 57 Hydraulic Module Integrated 3.8 Pipe Flushing 3.8.1 Purpose To remove dust, other particles and moisture, which could cause compressor malfunction if not flushed out before the system is run, the refrigerant piping should be flushed using nitrogen. As described in Part 3, 3.3.1 “Installation procedure”, pipe flushing should be performed once the piping connections have been completed with the exception of the final connections to the Hydraulic Module.

    Hydraulic Module Integrated 3.9 Gastightness Test 3.9.1 Purpose To prevent faults caused by refrigerant leakage, a gastightness test should be performed before system commissioning. 3.9.2 Procedure Notes for installers Warning Only dry nitrogen should be used for gastightness testing. Oxygen, air, flammable gases and toxic gases must not be used for gastightness testing.

  • Page 60 Hydraulic Module Integrated 3.10.2 Procedure Notes for installers During vacuum drying, a vacuum pump is used to lower the pressure in the piping to the extent that any moisture present evaporates. At 5mmHg (755mmHg below typical atmospheric pressure) the boiling point of water is 0°C. Therefore a vacuum pump capable of maintaining a pressure of -755mmHg or lower should be used.

    Hydraulic Module Integrated 3.11 Charging Refrigerant 3.11.1 Calculating additional refrigerant charge The additional refrigerant charge required depends on the lengths and diameters of the outdoor and indoor liquid pipes, and the indoor unit capacity of the connection. Table 3-7.1 shows the additional refrigerant charge required per meter of equivalent pipe length for different diameters of pipe.
