(3) Procedure and result of equipment selection
a.Procedure of equipment selection
Introduce the equipment selection procedure step by step.
b.Equipment selection and capacity check
① Selection of indoor unit.
Select suitable indoor unit according to the corrected load of indoor unit capacity.Corrected load
of indoor unit capacity=Load/Corrected ratio of cooling capacity related to temperature condition.
Referring to the corrected ratio chart of cooling capacity related to temperature condition, under
outdoor temperature of 35℃（95 ℉）DB and indoor temperature of 17℃（81 ℉）WB, the
corrected ratio of cooling capacity is 0.94.

② Selection of outdoor unit
The total capacity code of indoor units is 48. Please select suitable outdoor unit according to the
total capacity of indoor units and corrected situation.Capacity of outdoor unit=Total capacity of
indoor units/(Corrected ratio of cooling capacity related to temperature condition × Correction of
connection pipe length and height difference) .After calculating the capacity of outdoor unit, select
suitable outdoor unit according to 50%~135% of the capacity of outdoor unit.
In the example, capacity of outdoor unit=48/(0.94×0.95)=54.
Select the outdoor unit with capacity code of 160 and nominal cooling capacity of 14.1Kw(48000Btu/
h).
The capacity code ratio between indoor unit and outdoor unit is 48/48×100%=100%, which is
within 50%~135% and accords with the equipment selection standard.
③ Correction of outdoor unit capacity
Suppose the combination situation between indoor unit and outdoor unit is as below，GMV-48WL/
A-T(U).
Indoor unit: GMV-ND09PLS/A-T(U)×2, GMV-ND12PLS/A-T(U)×1, GMV-ND18PLS/A-T(U)×1
If the total capacity code of indoor units is bigger than the capacity code of outdoor unit, the capacity
of outdoor unit in rated condition equals to its rated cooling capacity. So the capacity of outdoor unit
under rated condition is 14.1Kw(48000Btu/h).
④ Referring to the corrected ratio chart of cooling capacity related to temperature condition, under
outdoor temperature of 35
℃（95 ℉）DB and indoor temperature of 17
℃（81 ℉）WB, the
corrected ratio of cooling capacity is 0.94.
⑤ Referring to the corrected ratio of connection pipe of 55m（180ft）long and height difference
between indoor unit and outdoor unit of 25m（82ft）（outdoor unit is lower than indoor unit）, the
corrected ratio is 0.95.
Capacity of outdoor unit=48×0.94×0.95=12.59Kw（42.86Btu/h）
⑥ Correction of indoor unit capacity
Capacity of each indoor unit=Capacity of outdoor unit × Total capacity of indoor units/Total capacity
of synchronously operating indoor units.
GMV-ND09PLS/A-T(U)：48×9/48=9kBtu/h
GMV-ND12PLS/A-T(U)：48×12/48=12kBtu/h

REFRIGERANT PIPING DESIGN 6 6.1 Warning on refrigerant leakage (1) Introduction of leakage detection method Procedures of leakage detection.Before ex-factory, the cut-off valves of gap pipe and liquid pipe of outdoor unit are closed. Please confirm it before installation.Before testing, apply some suitable lubricant on the joint of cap and pipe. Use two wrenches when fixing the cap.Connecting outdoor pipeline for testing is not allowed during leakage detection. The testing pressure of R410A system is 4.15MPa (for R22 system, it is 3.0Mpa). The medium of airproof test must be dry nitrogen. Increase the pressure slowly in three steps: Step one: Slowly increase pressure to 0.5MPa and maintain pressure for 5min. Big leakage may be found during leakage detection; Step two: Slowly increase pressure to 1.5MPa and maintain pressure for 5min. Small leakage may be found during airproof test; Step three: For R410A system, slowly increase pressure to 4.15MPa(for R22 system, it is 3.0Mpa) and maintain pressure for 5min. Tiny leakage may be found during strength test. Increase pressure to testing pressure and maintain pressure for 24h. Check if the pressure decreases. The test is passed if pressure doesn’t decrease. (2) Introduction of handling method of leakage Firstly, discharge the refrigerant and then charge nitrogen for leakage welding. The nitrogen charging way is the same as that in airproof test. Blow away the impurities and clean the pipeline after finishing welding. Finally, rearrange airproof test for leakage detection until there is no leakage. 6.2 Free branching system ODU Gas pipe Liquid pipe Connection pipe between outdoor unit and the first branching joint in indoor side Branching pipes of indoor units and connection pipes among indoor units Indoor unit 1 Branching joints among indoor units Connection pipes of branching joints among indoor units Branching pipes of indoor units and connection pipes among indoor units Indoor unit 2 Connection pipes of branching joints among indoor units Branching pipes of indoor units and connection pipes among indoor units Indoor unit 3 Connection pipes of branching joints among indoor units 16

Dc Inverter Multi VRF System Technical Sales Guide ③ Record additional refrigerant charge amount for future reference. Note: If the total length of liquid pipe is within 20m, no additional refrigerant is needed. When the compressor is not working after ensuring there is no leakage, charge the required additional refrigerant amount to the unit from the valve of liquid pipe of outdoor unit. When the pipe pressure increases and the additional refrigerant can’t be charged to the required amount quickly, please set the unit in cooling operation status and charge refrigerant from the low pressure maintenance port of outdoor unit. WIRING DESIGN 7 7.1 General wiring principle (1) All electrical work shall be done by professionals according to national and local laws and regulations.
