Cooling or heating capacity calculation method:
R410A outdoor unit capacity = outdoor unit capacity in rated condition × correction fac
-tor of indoor and outdoor temperature condition × connection pipe distance, correction
factor of height difference between indoor unit and outdoor unit.

Selection of outdoor unit
The total capacity code of indoor units is 208. 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 rel
-ated to temperature condition × Correction of connection pipe length and height di
-fference) .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=208/(0.94×0.95)=233
Select the outdoor unit with capacity code of 160 and nominal cooling capacity of 16KW.
The capacity code ratio between indoor unit and outdoor unit is 208/160×100%=130%,
which is within 50%~135% and accords with the equipment selection standard.
Ĺ Correction of outdoor unit capacity
Suppose the combination situation between indoor unit and outdoor unit is as below.
Outdoor unit:GMV-HY160WLT/A
Indoor unit: GMV-ND25PL/B×2, GMV-ND72PL/B×1, GMV-ND50PL/B×1, GMV-ND36PL/B×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 capa
-city. So the capacity of outdoor unit under rated condition is 16KW.
ĺ Referring to the corrected ratio chart of cooling capacity related to temperature
FRQGLWLRQXQGHURXWGRRUWHPSHUDWXUHRIć'%DQGLQGRRUWHPSHUDWXUHRIć:%WKH
corrected ratio of cooling capacity is 0.94.
ĻReferring to the corrected ratio of connection pipe of 55m long and height difference
between indoor unit and outdoor unit of 25m (outdoor unit is lower than indoor unit),
the corrected ratio is 0.95.
ļCorrection of indoor unit capacity
Capacity of each indoor unit=Capacity of outdoor unit × Total capacity of indoor unit
s/Total capacity
of synchronously operating indoor units.
GMV-ND25PL/B ˖16×25/208=1.92KW
GMV-ND72PL/B ˖16×72/208=5.54KW
GMV-ND50PL/B ˖16×50/208=3.85KW

REFRIGERANT PIPING DESIGN
5.1 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.

Note ˖
ķ The refrigerant amount inside the system before ex-factory doesn’t include the required additional
refrigerant charge amount inside the pipeline system of indoor units and the pipeline system
connecting indoor unit and outdoor unit.
ĸ For the length of connection pipe in field, the required additional refrigerant charge amount shall be
confirmed according to liquid pipe size in field and its length.
Ĺ 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.

length: 5 m, without height drop between units
d. Rated heating capacity test conditions: indoor 20°C DB, outdoor 7°C DB/6 °C WB; connection pipe
length: 5 m, without height drop between units
e. The total capacity of connected indoor units must be in the range of 50%~135% of the outdoor unit
capacity. The relevant parameters can be corrected by referring to the unit capacity correction table.
f.dThe above parameters are tested based on the standard connection pipe length. In the actual
project, the parameters should be corrected referring to the capacity correction for the long connection
pipe of units

PART OF PV INTRODUCTION
10.1 PV of development and future
Solar is renewable resource and it was attached importance which clean,cheap,enough. solar is used
more and more openly on the world. It was for cutting down the cost of production. such as advancing
to decrease resource for architecture,depressing to let co2 and so on.The development process is as
follows.Basis on EPIA forecast,the cut-off date to forecast is 2050,solar generate
to grid more than 24% on all resource.
10.2 Photovoltaic direct-driven inverter GMV mode
10.2.1 Photovoltaic direct-driven inverter GMV system of configuration
GREE photovoltaic direct-driven inverter GMV is very well air-condition system which can
generation to grid and supply electricity to unit.The system reach to high level first of
all.It have fine mode to work.generation or supply need to less than 10ms at short notice.
The system process is as follows.
