GENERAL DESCRIPTION
General air condioning system
1) convenonal air condioners cool the enre enclosed environment.
2) They act as “heat exchangers”, equiring an interior unit (evaporator) to blow cool
air into the interior and an exterior unit (condenser) to exhaust exchanged heat
to the outdoors.
Portable air condioning system
1) The 5KK14BEA2AA00/5KK21BGA2AA00/5KK
30BGA2AA00 is a spot cooler which directs
cool air to parcular areas or objects.
2) The 5KK14BEA2AA00/5KK21BGA2AA00/5KK
30BGA2AA00 has the following features.
3) The innovave design of the KK14BEA2AA
00/5KK21BGA2AA00/5KK30BGA2AA00 has
resulted in one compact unit, replacing the
need for two separate units.
4) With the whole cooling system built into one
compact unit, the 5KK14BEA2AA00/5KK21BG
A2AA00/5KK30BGA2AA00 requires no piping
and can be easily transported and installed.
5) The 5KK14BEA2AA00/5KK21BGA2AA00/5KK
30BGA2AA00 is economical because it cools
only the area or objects which need to be
cooled.

Compressor
The construcon of a rotary type compressor is divided into two mechanisms; the
drive mechanism (compressor motor), and the compression mechanism (compres-
sor). When the rotor sha of the motor (drive mechanism) turns, the roller (com-
pression mechanism) rotates to compress the refrigerant.

Compressor operaon
1) Start of compression
1) The cylinder is filled with low pressure gas.
2) Since pressure in the discharge chamber
is higher than in the cylinder, the dis-
charge valve is kept closed.
2) Sucon and compression
1) The pressure in the cylinder increases
gradually.
2) Refrigerant sucon begins on the suc-
on side of the cylinder.
3) The discharge valve remains closed.
3) Discharge
1) The pressure in the cylinder exceeds that
in the discharge chamber, and the dis-
charge valve opens.
2) On the sucon side, refrigerant sucon
connues.
4) Compleon of compression
1) When compression is completed, all of
the refrigerant has been drawn from the
sucon chamber.
2) Operaon then returns to step 1)(Start
of compression) and the above process
of sucon and compression connues
repeatedly in succession.

Compressor lubricaon
The lubricaon system is comprised of a
hollow sha, an oil scraper mounted at the
end face, hollow sha, a sha journal (sha
bearing), and the lubricaon groove for the
sha journal.
The lubricaon groove is wider than the oil
hole. When the sha turns, oil is scraped
upward by the oil scraper along the inside
diameter of the hollow sha. The oil is fed
through the oil hole by centrifugal force,
then supplied to the lubricaon groove for
each sha journal, lubricang the bearing.
In this lubricaon system, oil enters into
each bearing separately and returns to the
oil reservoir. This system effecvely pre-
vents bearing temperature increases, and
offers high reliability.
In addion, the specially treated sha jour-
nal keeps the bearing from being
damaged during high temperature operaon.
Condenser
1) The condenser is a heat exchanger with
Louver fins.
2) Heat is given off and absorbed by air be-
ing pulled across the condenser fins by
the axial fan. The air is then expelled
through the condenser air outlet.

Capillary Tube
The capillary tube is a long thin tube
that ulizes line flow resistance as an
expansion valve. The length and the
inner diameter of the capillary tube
are determined according to the ca-
pacity of the refrigeraon system,
operang condions, and the amount
of refrigerant. The high pressure, high
temperature liquid refrigerant sent
from the condenser expands rapidly as
the refrigerant is sprayed out through the fixed orifice in the capillary tube. As a
result, the temperature and state of the refrigerant becomes low and mist-like, and
therefore evaporates easily.
Evaporator
The evaporator is a heat exchanger covered with slit
fins. Heat is removed from the air being pulled across
the evaporator by the centrifugal fan.
The resulng cool air is expelled through the cooling air
ducts.
Accumulator
The accumulator is mounted on the sucon gas pip-
ing between the evaporator and the compressor.
The accumulator separates the liquid refrigerant from
the gas refrigerant, allowing only the gas refrigerant to
enter the compressor. In the accumulator, sucon gas
isled into a cylindrical vessel where the speed of the
gas is decreased.
This process separates the refrigerant contained in
the gas by the force of gravity, causing the refrigerant to accumulate at the boom
of the vessel. As a result, the compressor is protected from possible damage caused
by liquid refrigerant intake.

Control panel
Before operang the unit, it is important to be familiar with the basic operaon of
the control panel.
1. POWER BUTTON
• Acvates unit when POWER BUTTON is pressed.
• Fan starts on low speed.
• If POWER BUTTON is pressed during operaon, unit stops.
2. BLOWER BUTTON
• Changes fan speed from LOW to HIGH when pressed.
3. SPOT / COOL BUTTON
• Acvates compressor and begins producing cool air 5 seconds aer
buon is pressed.
• Regulates temperature based on outlet cool air temperature.
4. ROOM / COOL BUTTON
• Acvates compressor and produces cool air 5 seconds aer buo n
is pressed.
• Regulates temperature based on inlet ambient air temperature.
