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 ﬁ lled 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 eﬀ ec vely pre-

vents bearing temperature increases, and

oﬀ ers 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 ﬁ ns.

2) Heat is given oﬀ and absorbed by air be-

ing pulled across the condenser ﬁ ns 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 ﬂ ow 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 ﬁ xed oriﬁ ce 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

ﬁ ns. 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.
