2. EXPLANATION OF TERMINOLOGY

1)Air Conditioning:

Keeping room air in an optimum condition, depending on the use or purpose. (Cooling, heating, humidity regulatiog,air cleaning, etc.)

2) Cooling (Heating) capacity:

Calorie which is able to be released (or added) per a unit time in room. It is expressed in Kcal/h, BTU/h, W or RT

3)Humidity

(1) Absolute humidity: The amount of vapor contained in the air. Generally it is equal to the amount of vapor by g unitcontained in 1m3 air, and is expressed in g/m3.

(2) Relative humidity: The ratio between the amount of vapor contained in the air and the maximum amount (theamout of saturated vapor) of vapor capable of containing at that temperature in %.

*Relative humidity= Actual vapor pressure/Saturated vapor pressure x 100= Actual vapor pressure of dew point temperature/saturated vapor pressure of dry-dulb temp.

x 100(3) Dew point temperature: The surface temperature which starts dewing on the surface when it is cooled in the air.

4) Heat

(1) Latent heat and sensible heat:Heat which causes a change in the state of a substance, with its temperature being constant, is called latent heatwhereas heat which changes the temperature of a substance is called sensible heat. Latent heat is expressed interms of calories needed to cause a change of state of a substance per 1 kg. The following equation shows that QKcal is needed to change state of a substance weight G Kg when the latent heat is L Kcal/kg. (Q=GL)

(2) Thermal flow1 Radiation : A phenomenon which termal energy as an electro-magnetic wave is transmitted directly from a

thermal source.2 Conduction : A phenomenon which transmits from high to low temperature when there is a temperature

difference partially in a substance.3 Convection : When the temperature of a fluid like gas or liquid changes by heat, the high temperature part

expands and thus the density drops to cause to be light whereas the low themperature part is tobe heavy. It means a phenomenon that heat is transmitted together when floating happens by the

weight difference of air.

5) Quantity of heat

(1) Kcal: Adding or releasing heat to or from a substance changes its temperature. This change of temperature is inproportion the heat added or released This heat is called calorie which is expressed in Kcal or cal. 1 Kcal isequal to the amount of heat required to raise the 1˚C Temperature of 1kg water 4˚C.

(2) BTU: 1 BTU is equal to the amount of heat required to raise the 1˚F temperature of 1 lb water.•1 Kcal=3.968 BTU, 1 BTU=0.252 Kcal

6) Refrigerating Ton (RT):• 1 RT is equal to the capacity which makes 1 Ton water 0˚C into ice 0˚C in 24 hours. It is expressed in calorie

required to freeze water 1 Ton water 32˚F(200 lb) into ice 32˚F, and when using the solidification latent heat ofwater, 1RT is as follows

• 1 RT= 144BTU/lb x 200 lb/24hr = 12,000 BTU/lb = 3,024 Kcal/h = 3.517 KW

7)Pressure:

Pressure p is the normal (perpendicular) force exerted by a fluid per unit area against which the force is exerted.Absolute pressure is the measure of pressure above zero; gauge pressure is measured above existing atmosphericpressure. the unit used for pressure is newtons per square meter (N/m 2), also called a pascal (Pa). The newton is aunit of force. Standard atmospheric pressure is 101,325 Pa=101.3 kPa.

8) Specific heat:

The specific heat of a substance is the quantity of energy required to raise the temperature of a unit mass by 1 K.

9) Horse Power(Hp)

• 1 Hp = 0.75 KW = 645 Kcal/h, 1W = 086 Kcal/h

10) Conversion of unit

(1) Temperature conversion (˚C ˚F)• ˚F = 9/5˚C + 32, ˚C = 5/9(˚F-32)

11) Compressor:

Absorb and compress the low pressure gasified refrigerant in evaporator and let it flow into condenser. At this time,the low pressure is to be kept in evaporator and the refrigerant gas flows into condenser as high pressure condition.The most economical condition of compressor for an proper operating is when the refrigerant gas absorbed intocompressor is in dry-saturated condition. The overly-heated suction gas may cause the mechanical ability ocompressor to be reduced and the cylinder clearance of compressor to be re-expanded, and as a result, therefrigerant may be used without its refrigerating effect. The types of compressor is Recipro. type, Rotary type, Scroll

type, Screw type, etc. and consists of cylinder, piston, vane, shaft, bearing, case and accumulator for structurereason.

12) Condenser:

The high temperature/high pressure refrigerant gas compressed by compressor is sucked into condenser andliquified by cooling. The condenser is cooled by the forced-convection of fan. The calorie emitted from condenser isequal to the sum of the heat absorbed in evaporator and the calorie used for compressor operationg.

13) Evaporator:

Absorb the heat from room air by forced-convectionThe liquid refrigerant in evaporator is evaporated by absorbing heat from room air and flowed into compressor as a

gasified state. The evaporating temperature of refrigerant is decided by pressure, which is decided by thetemperature of suction air and the wind flow, and the pressure in evaporator is normally 5Kg/cm2G and theevaporating temperature is 5~8˚C

14) Capillary (Expansion Valve):

Regulate the refrigerant flow into evaporator get, lower the pressure of refrigerant, and lead it into a liquid of lowtemperature and low pressure. The type of capillary is generally a thin and long copper tube of 0.6~2.0mm2 innerdiameter and 1~2m long. The resistance of tube causes to turn into a liquid of low pressure and low temperature.

15) Dryer:

Any moisture in refrigerating cycle may cause the compressor motor to be damaged or turn into an ice state it selfin the middle of cycle, which blocks the flow of refrigerant. Dryer is installed in a cycle for the purpose of removing

such moisture.There are two types of dryer; a liquid line dryer which is connected serially to the condenser outlet and a suction linedryer which is connected serially to the suction line, with a desiccative in dryer.The dryer is designed for uni-directional flowing of the refrigerant.

16) Strainer:

Strainer serves to remove foreign substances from refrigerant by a metal net pelt of fine grid or a glass wool beinginserted into metal vessel and refrigerant being passed through between the interval. The mounted position isbetween condenser and capillary expansion valve.

17) Service valve:

Service valve is used for vacuum working and refrigerant filling. Front seat is called a state which cap is opened andvalve is completely rotated clockwise and refrigerant stops flowing in that condition, whereas back seat is called astate which valve is totated completely counter-clockwise and refrigerant flows. In case of pressure measurementsor vacuum work form service valve, the back seat condition is changed into some fornt seat condition. Product isreleased in front seat condition, so the back seat by brake-in is not needed.

18) Motor:

Generates a rotating force by electric power and supply the driving force to fan and blower in both indoor andoutdoor of air conditioner.


6/175

19) Fan:

Generates forced air flow. The forced air passes throngh heat-exchanger and blow out the heat (or give the heat onthe contrary) from heat-exchanger.A Fan can be classified by axial fan and radial fan. Generally we call axial fan (mostly propellar fan) as (Fan).

20) Blower (Cross Flow Fan: C.F.F):

A kind of Fan. It also generates forced air flow and air flows cross over axis of FanBlower is placed indoor unit, so a small size, high wind flow and low noise type is used.

21) Thermostat:

Sense the temperature of air or heat exchangers and controlls automatically room temperature by switchingcompressor on/off depending on temperature. Thermostat is used for a mechanical type model and thermistor for amicom type control method.

22) Capacitor:

Get shift the phase of input electricity for compressor or fan motor, which leads starting direction and torque to thecompressor motor or fan motor for aircon and make the operating efficiency better during operation.

23) Over load protector (O.L.P):A protective device of automatic retrip type which is placed in the compressor and trip(cut) off the power ofcompressor moto against the overheat and overcurrent of compressor.At this time, compressor stopps operating by power off and only fan is on work. Generally the trip temperature isaround 120°C and the return thmperature is around 90°C.

24) High pressure switch(H.P.S/W):

A protective device of automatic return type which protects compressor and the discharge pipes from overload bysensing the discharge pressure of compressor, working at an abnormal high temperature, and shutting off theelectric circuit. Generally the working pressure is around 28kg/cm2G and the return pressure is 23 kg/cm2G.

25) Accumulator:A kind of liquid refrigerant separator which prevents the liquid refrigerant getting into compressor and is installed inthe suction inlet of compressor.

26) Reversing valve (4 way valve):

Convert the flow of refrigerant upon cooling/heating switch-over, electrically power on when heating and off whencooling, be installed in outdoor, and have four connecting valves as shown in the name. The refrigerant passingthrough compressor always flows to a constant direction and is able to reverse-operate completely the refrigeratingcycle of both cooling and heating by a reversing valve. Consist of reversing valve and solenoid valve. The mainvalve in reversing valve uses a nylon resin which is deformed by heat 120˚C or over and thus causes valve not towork, so be cautious while operating or when welding.

27) Check valve:Prevent refrigerant from reverse flow in refrigerating cycle. It is installed in a place where it is necessary to preventthe reverse flow of refrigerant in a copper pipe. It has a mechanical structure and attached to the opposite of aheating capillary to expand the heating/cooling model by two speeds, and is constructed so as to flow throughcapillary in heating and through the check valve in cooling only.

28) Solenoid valve

Regulate the refrigerant flow by refrigerant on/off in cycle which refrigerant flows according as the valve operatesthrough a coil unit being powered on. Mainly it is used when reversing the 4 way valve of a cooling/heating model orconstruction each unit cycle of multi model.

3. PRINCIPLE OF OPERATING AIR-CONDITIONER

1) Four elements of air conditioning

(1) Temperature:The dry-bulb temperature by cooling or heating room air.

(2) Humidity:

A comfortable humidity condition of room air is generally kept by the relative humidity of air, and the room air iscontrolled into a given relative humidity condition.

(3) The degree of purity:Remove dusts in the air, and keep smoke from exceeding the allowable degree of concentration.

(4) Air flow:To disperse properly the air regulated in temperature, humidity and the degree of purity into indoor, make anappropriate air flow and keep uniformaly the temperature/humidity condition of room unit.

•Satandard for feeling comfortable

2) Principle of cooling Air-Conditioner

• Sprinkling with water in summer cause to cool surroundings because water absorbs the heat of surroundings• Gasifying a liquid (R-22) which is easier to evaporate than water cooler because water evaporates at 100˚C under

1 atmosphere but freon gas (R-22) does a very low temperature of -40°C.• It is an Aircon that the principle is used for

fl

The role of each cycle

1) Compression:The gasified refrigerant evaporated is absorbed into compressor through the suction pipe, and the compressed by apiston in cylinder and turned into a gas of high temperature and high pressure which is able to be liquified in a roomtemperature.

2)Liquification:

The gas of high temperature and high pressure in compressor is cooled by air in condenser and liquified by acondensing heat.

3)Expansion:

With passing through the capillary tube, the high pressure refrigerant liquified in condenser turns into a low pressurecondition, which is easy to evaporate.

4)Evaporation:

The liquid refrigerant of low temperature and low pressure passed though the capillary tube absorbs the room air heatin evaporator and evaporates into a gas.

On pipe connection, discharging air in pipe is air purge, do purge air necessarily, because it may cause pressurerising, operating energy loss, compressor overheating, cooling efficiency drop.Before the shipment, our products are filled with the additional refrigerant for air purge. On installation, Air purges theindoor unit and pipe by using refrigerant of the outdoor unit.

Caution) open the valves coke till it cannot rotate by stopper.Fasten reliably the valve cap with tools of spanner, etc.Use 4mm L-wrench to close or open the valve coke.

Open the cap of the valve B & A

Check the leakage of pipe connection portion.

Open completely the stopper of the valve B & A.

Close the each valve cap.

Check the gas leakage.

Open the stopper of valve B by 45˚C, close the stopperafter 10sec.(At this time, tools using control the pipe,exclusive L-wrench.)

* Open needle cap of the valve A, by pressing needlevalve during 3 sec, discharge gas, and repeat 3 timesin this order.

• Close the connection tube portion, If no leakage,proceed *.

• If it is required to repair for gas leakage, afterdischarge the refrigerant gas and repair the part ofleakage, vacuum again and charge refrigerant.

6. Additional refrigerant charging

When measure the pressure with lack of the refrigerant, measure the pressure with manifold gauge after connecting tovalve.In case that the pressure is less than the standard, add the refrigerant as the following method.If the refrigerant contains too excessive refrigerant, liquid refrigerant will down the product quality.

Preparation of manifold gauge• Check that three valves is attached properly.• Check that left side (low pressure), right side (high-

pressure) handle is closed completely.• Check that there is a pin at the end of low pressure hose.

(1) Connect the middle hose of the pressure gauge to gascylinder, open the Gas side service valve of the gascylinder. (At this time, do not turn gas cylinder over.)

In holding state, the low pressure becomes differentaccording to the ambient temperature of the outdoor unit.

(3) operate airconditioner in cooling mode(fan speed/strong)

(4) In case of lower pressure than that, turn overrefrigerant gas cylinder.

(5) Loose the low-pressure valve of the pressure gaugeduring 2-3sec. And close again and wait during 4-5sec.

(7) After close the refrigerant gas cylinder, remove thehose of the low-pressure side, and close the cap of the

valves in original state.

(6) Till the pressure become 4-5kg/cm2 , repeat (5) work.

In case of proper refrigerant, pressure is about to 0 at first,10min later the pressure is stable in 4-5kg/cm2 .(The pressure can be changed according to the roomtemperature and humidity.)

(2) Open the low-pressure sided valve of the pressuregauge, discharge air in the hose. After 2-3sec. releasethe low part cap of the Gas side service valve andconnect the low-pressure sided hose(blue) to this place.Close the low-pressure sided valve after full connection.

Precautions in charging refrigerant

• Before connect the hose of the pressure gauge to airconditioner, work necessarily (1), (2).• Do not encloses a lot amount of the refrigerant at once.• As the above message is the explanation of additional injection of the refrigerant.

When charge first after repairing the refrigerant cycle, vacuum sufficiently inside of the airconditioner and then chargerefrigerant.

• When charge the additional refrigerant, after operate necessarily in cooling mode (strong).

• In case that that is not a cooling mode, the low-pressure side can be changed.)

• Charging Additional refrigerant per length

7. Vacuum Method

The purpose of vacuum is to remove air and moisture in the refrigerant system.It is important to vacuum in the system. Air and moisture in the system may cause Pressure-rising, operating energyloss, compressor deterioration and freezing.In case that there is no remaining refrigerant in the tube because of leakage and repairs, vacuum by opening the gasside and the liquid side service valve.After the pipe connection of indoor and outdoor, must vacuum the tube after close the liquid side and the gas side

service valve.If vacuum is made completely, start directly to charge refrigerant in order not to be intruded by open air.And in case that required to discharge refrigerant for after-service, discharge slowly and do vacuum in order not todischarge refrigerating oil of the compressor.

4.MOVING METHOD

• Refer to it on house moving and movement of the installation place.

1) Do pump down (refer to details of pump down)2) Disconnect the power cord.3) Disconnect connection cable from indoor and outdoor unit.4) Remove the flare nut for pipe connection from indoor unit.

At this time, wrap the pipe and tube of indoor unit with cap or vinyl envelope, etc so that scales do not enter it.5) Disconnect connection pipe from outdoor unit

At this time, wrap the pipe and tube of indoor unit with cap or vinyl envelope, etc so that scales do not enter it.6) To prevent middle part of connection tube from bending or cracking, wrap in the proper size, and then preserve

and move it with cables.7) Move indoor and outdoor unit to specified place.8) Dissolve the indoor plate from the wall, and then move the place to install.

About pressure of the refrigerant cycle.

• If an actual temperature is low, the pressure become low.

• If the amount of refrigerant is insufficient, the pressure become low.• Dust is attached to the filter of indoor unit, the pressure of the low pressure part become low for decreasing amount of

the wind• By blocking the air suction of outdoor unit, decreasing amount of the wind make an operation of OLP.

- In case of becoming low in low pressure part:evaporator an suction pipe is freezing.

- In case that the refrigerant is too much:If aircon operates in a low actual temperature, evaporator and suction pipe is freezing.

- In case that the refrigerant is too small: overheating compressor operates overload.

4. FUNCTION OF MAIN COMPONENTS

1. ROTARY SWITCH (SELECTOR)

Please refer to the part of selector in the chapter 9 (Wiring Diagram).The rotary switch (selector) controls the fan motor’s rotation speed, and has five positions.The function of the five position is as follow.

OFF: This po sition s tops all operations of the airconditioner.

HIGH COOL: This position provides the maximum airflow for rapid cooling, dehumidifying anddust removing operations.(Use this position on sultry summer days.)

LOW COOL: This position provides the minimum air flowfor quiet cooling, dehumidifying operations.(Use this position on suitable for night-time.)

HIGH FAN: This position provides the maximum air fiowalone fan operation without coolingoperation.

LOW FAN: This position provides the minimum air flowair flow alone fan operation without coolingoperation.

2. THERMOSTAT (TEMPERATURE CONTROL)

The Thermostat automatically starts and stops operation in order to keep the roomtemperature at a proper level, and this results in efficient use of power and economical

cooling.

Turn clockwise for a cooler room temperature.

Turn counter-clockwise for a warmer room temperature.

3. MOTORThe motor is used to rotate the indoor and outdoor fan so that the room air can be recirculated.

4. FAN

BLOWER FAN: The Blower draws hot air from the room through the Evaporator and then discharges it back into thecool air. It circulates the room air.

PROPELLER FAN: The propeller draws outdoor air through louvering and cools Condenser, and then blows the hotair out.

5. CAPACITORThe Capacitor enlarges the difference of phase between main coil and sub coil so that the Compressor and Fan Motorstarts well.

6. ACCUMULATORThe Accumulator blocks the unflow of liquid refrigerant and impurities into the Compressor.
