6. Natural Wind by CHAOS logic

There are common rules in the irregular changes amid the breeze of highlands and valleys, the sound of
streams, the songs of birds in the forest and brain waves of relaxation.
Mmm... the breath-taking and touchy feeling of wind from the deep mountains and dark valleys.
Through analysis in its chaos simulator, Goldstar has successfully created such a feeling of freshness and
serenity by analyzing the frequency of natural wind.

Generally natural wind has the following character (frequency-Magnitude), for example dark vally, sea, moun­tain wind.

So as to make a similar Natural wind function, Indoor fan speed is shifted to high from low or reversely in
according to the CHAOS logic.

9. Deice Control

ƒU Deicing operation is controlled by timer and sensing the indoor pipe temperature.
ƒU Deicing operation checks the indoor pipe temperature and Intake-air temperature at 25 minutes and 60 min-

utes on starting of heating operation, and discriminates by temperature difference.

ƒU When the heating operation passed 25 minutes, the temperature (¡ T1=TE1–TR1) is checked and memorized

with checking the indoor pipe temperture (TE1) and the indoor Intake-air temperature (TR1).

ƒU When the heating operation passed 60 minutes, deicing operation checks the indoor pipe temperature (TE2)

and the indoor Intake-air temperature (TR2), and checks the temperature difference (¡ T2=TE2–TR2) and the
temperature difference ¡ Td(=¡ T1–¡ T2) of ¡ T1, ¡ T2.
If the temperature difference (¡ Td) become more than the option temperature, deicing operation starts.

ƒU At that time, deicing operation time is decided.
ƒU The deicing operation time stops after deicing operation started.
ƒU If deicing operation start, above heating operation time is reset, so if deicing operation is finished, the heating

operation time is recounted.

ƒU The deicinig time and the operation diagram are as following.

1) Preparation of pipings

1. Cut the pipes and the cable.

• Use the accessory piping kit or the pipes purchased

locally.

• Measure the distance between the indoor and the

outdoor unit.

• Cut the pipes a little longer than measured distance.

• Cut the cable 1.5m longer than the length of pipe.

2. Remove burrs.

• Remove burrs from cut edges of pipes.

• Turn the pipe end toward down to avoid the metal

powder entering the pipe.

Caution:

If burrs are not removed, they may cause a gas leak­age.

3. Flaring the pipes.

• Insert the flare nuts, mounted on the connection

ports of both indoor and outdoor unit, onto the cop­per pipes. Some refrigerant gas may leak, when the
flare nuts are removed from the indoor unit, as
some gas is charged to prevent the inside of the
pipe from rusting.

• Fit the copper pipe end into the Bar of flare tool

about 0.5~1.0mm higher. (See illustration).

• Flare the pipe ends.

4. Tape the flaring portion to protect it from the

dust or damages.

1. Air purging

Required tools : hexagonal wrench, adjustable

wrench, torque wrenches, wrench to
hold the joints, and gas leak
detector.

The additional gas for air purging has been charged
in the outdoor unit.
However, if the flare connections have not been done
correctly and there gas leaks, a gas cylinder and the
charge set will be needed.

The air in the indoor unit and in the piping must be
purged. If air remains in the refrigeration pipes, it will
affect the compressor, reduce to cooling capacity, and
could lead to a malfunction.

• Procedure

(1) Recheck the piping connections.
(2) Open the valve stem of the 2-way valve

counterclockwise approximately 90°, wait 10
seconds, and then set it to closed position.

– Be sure to use a hexagonal wrench to operate

the valve stem.

(3) Check for gas leakage.

– Check the flare connections for gas leakage.

(4) Purge the air from the system.

– Set the 2-way valve to the open position and

remove the cap from the 3-way valve’s service
port.

– Using the hexagonal wrench to press the valve

core pin, discharge for three seconds and then
wait for one minute. Repeat this three times.

(5) Use torque wrench to tighten the service port

nut to a torque of 1.8kg.cm.

(6) Set the 3-way valve to the back seat.
(7) Mount the valve stem nuts to the 2-way and 3-

way valves.

(8) Check for gas leakage.

– At this time, especially check for gas leakage

from the 2-way and 3-way valve’s stem nuts,
and from the service port nut.

Caution

If gas leakage are discovered in step (3) above,
take the following mesures :

If the gas leaks stop when the piping connections
are tightened further, continue working from step (4).
If the gas leaks do not stop when the connections
are retightened, repair the location of the leak,
discharge all of the gas through the service port,
and then recharge with the specified amount of
gas from a gas cylinder.

Service port unt.
Be sure, using a torque wrench to tighten the service port nut (after using the service port), so that it prevents the
gas leakage from the refrigeration cycle.

* CAUTION : Do not leak the gas in the air during Air purging.

the service port.

(4) Air purging of the charge hose.

– Open the low-pressure valve on the charge set

slightly to air purge from the charge hose.

(5) Set the 2-way valve to the closed position.

(6) Operate the air conditioner at the cooling

cycle and stop it when the gauge indicates
1kg/cm2g.

(7) Immediately set the 3-way valve to the closed

position.

– Do this quickly so that the gauge ends up

indicating 3 to 5kg/cm2g.

(8) Disconnect the charge set, and mount the 2-

way and 3-way valve’s stem nuts and the
service port nut.

– Use torque wrench to tighten the service port

nut to a torque of 1.8 kg.m.

way valve are set to the closed position.

(2) Connect the charge set and a gas cylinder to

the service port of the 3-way valve.

– Leave the valve on the gas cylinder closed.

(3) Air purging.

– Open the valves on the gas cylinder and the

charge set. Purge the air by loosening the flare
nut on the 2-way valve approximately 45° for 3
seconds then closing it for 1 minute; repeat 3
times.

– After purging the air, use a torque wrench to

tighten the flare nut on the 2-way valve.

(4) Check for gas leakage.

– Check the flare connections for gas leakage.

(5) Discharge the refrigerant.

– Close the valve on the gas cylinder and

discharge the refrigerant until the gauge
indicates 3 to 5 kg/cm2g.

(6) Disconnect the charge set and the gas

cylinder, and set the 2-way and 3-way valves
to the open position.

– Be sure to use a hexagonal wrench to operate

the valve stems.

(7) Mount the valve stem nuts and the service

port nut.

– Use torque wrench to tighten the service port

nut to a torque of 1.8 kg.m.

– Be sure to check for gas leakage.

• Procedure

(1) Confirm that both the 2-way and 3-way valves

are set to the back seat.

(2) Connect the charge set to the 3-way valve’s

port.

– Leave the valve on the charge set closed.
– Connect the charge hose with the push pin to

the service port.

(3) Open the valve (Lo side) on the charge set

and discharge the refrigerant until the gauge
indicates 0 kg/cm2G.

– If there is no air in the refrigerant cycle (the

pressure when the air conditioner is not
running is higher than 1 kg/cm2G), discharge
the refrigerant until the gauge indicates 0.5 to 1
kg/cm2G. if this is the case, it will not be
necessary to apply a evacuatin.

– Discharge the refrigerant gradually; if it is

discharged too suddenly, the refrigeration oil
will also be discharged.

(All amount of refrigerant leaked)

• Procedure

(1) Connect the vacuum pump to the charge set’s

center hose

(2) Evacuation for approximately one hour.

– Confirm that the gauge needle has moved

toward -76 cmHg (vacuum of 4 mmHg or less).

(3) Close the valve (Lo side) on the charge set,

turn off the vacuum pump, and confirm that
the gauge needle does not move (approxima­tely 5 minutes after turning off the vacuum
pump).

4. Gas Charging

(After Evacuation)

• Procedure

(1) Connect the charge hose to the charging

cylinder.

– Connect the charge hose which you dis-

connected from the vacuum pump to the valve
at the bottom of the cylinder.

– If you are using a gas cylinder, also use a scale

and revers the cylinder so that the system can
be charged with liquid.

(2) Purge the air from the charge hose.

– Open the valve at the bottom of the cylinder

and press the check valve on the charge set to
purge the air. (Be careful of the liquid
refrigerant). The procedure is the same if
using a gas cylinder.

(3) Open the valve (Lo side on the charge set and

charge the system with liquid refrigerant.

– If the system can not be charged with the

specified amount of refrigerant, it can be
charged with a little at a time (approximately
150g each time) while operating the air
conditioner in the cooling cycle; however, one
time is not sufficient, wait approximately 1
minute and then repeat the procedure
(pumping down-pin).

(4) Immediately disconnect the charge hose from

the 3-way valve’s service port.

– Stopping partway will allow the gas to be

discharged.

– If the system has been charged with liquid

refrigerant while operating the air conditioner
turn off the air conditioner before disconnecting
the hose.

(5) Mount the valve stem nuts and the service

port nut.

– Use torque wrench to tighten the service port

nut to a torque of 1.8 kg.m.

– Be sure to check for gas leakage.

\

This is different from previous procedures.
Because you are charging with liquid refrigerant
from the gas side, absolutely do not attempt to
charge with larger amounts of liquid refrigerant
while operating the air conditioner.

Notice :

Temperature difference between intake and discharge air depends on room air humidity. When the room air
humidity is relativery higher, temperature difference is smaller. When the room air humidity is relatively lower
temperature difference is larger.

2. Check temperature and pressure of refrigeration cycle.

Notice :

1. The suction pressure is usually 4.5~6.0 kg/cm2G at normal condition.

2. The temperature can be measured by attaching the thermometer to the low pressure tubing and wrap it with
putty.
