2-7-2. Operation theory of refrigeration cycle components
■ Condenser
1) Role: A device which radiates heat to the outside (water/air) to make liquid state for the high
temperature / high pressure gas refrigerant discharged from compressor
2) Types
A. Air-cooling Type : Condense air by circulating naturally or manually.
1) Natural Convection Type : Used for the household refrigerator which has small condensing
capacity.
2) Manual Convection Type : Circulate air manually by FAN-Motor (Large capacity)
B. Water-cooling Type : Make cooling water pass through the pipe in the condenser (Large
capacity)
※ Location
① CLUSTER heat-radiating type : All Pipes effective for radiating heat are formed in the
right/left, and front side of refrigerator with hard urethanes and radiate heat through the
whole surfaces of cabinet to ambient air.
② Install the condenser on the outside of the product. (An old model)
③ Make them cluster at the lower part of product and radiate heat manually by fan.
☞ Radiate condensed potential heat up to liquefy completely and make change the state
without changing the gas temperature itself.
※ Pipe thickness
① Low pressure: 6.3mm ② High pressure : 4.7mm ③ Capillary : About 0.4-0.8mm
※ Condenser length (Based on 300ℓ): 26.5 M
① Assistance : 5 M ② HOT-PIPE: 6.6 M ③ CLUSTER-PIPE: 15 M
■ Capillary
1. Role: A device which makes low temperature and pressure refrigerant by reducing the
pressure the normal temperature / high pressure liquid refrigerant condensed from
condenser, and supply it to the evaporator.
A. To evaporate more lower temperature in case of evaporation.
B. It flows to the evaporator without back flowing to condenser, if compressor stops, and the
difference of pressure between high pressure and low pressure is small so it is easy to
operate the compressor again.
2. Outline
A. Thickness : About 0.4-0.8ßÆ
B. Length : It is changeable to low temperature and pressure (10->5ß∏/ß≤) depends on the
2M of thin and long copper pipe wall resistance.

2-7-2. Operation theory of refrigeration cycle components
■ Evaporator
1. Role: As the low pressure liquid refrigerant flowed from capillary absorbs heat inside of the
refrigerator, it becomes low pressure gas and refrigerate the foods.
2. Theory: The low pressure refrigerant flowed to evaporator operates cooling which takes
ambient evaporated potential heat with maintaining the evaporation up to evaporate
completely.
3.Types of Evaporator
A. ROLL-BOND Evaporator → Direct Cooling ONE-DOOR Type
☞ Rolled and adhere the 2 aluminum plate and then make refrigerant passage.
B. PIN-PIPE Type → Indirect cooling TWO-DOOR Type
☞ a small aluminum plate on the aluminum pipe to increase the cooling effect.
■ Compressor
1. Role: It operates same as pump which pull out the subterranean water. It inhales the low
temperature and pressure refrigerant gas (flowed out) from evaporator and make high
temperature and pressure refrigerant liquid in the compressor and send it to the condenser.
2. Type of Condenser
a. Back-and-forth motion type: A method that pistol makes back-and-forth motion through
shaft and cylinder of motor rotation and compresses. ※ Used for household refrigerant
b. Rotary Type: A method that inhales the refrigerant gas through the gap between the
outside of rotor electric attached on the shaft and the inside of cylinder and compresses.
c. Centrifugal Type
3. Please insert the explanation of inverter comp operation theory.
■ Dryer
1. Role: Absorb the moisture from the refrigerant that refrigeration cycle circulates and
eliminate the foreign substance.
2. Structure: If even some moisture is included refrigerant is impossible to circulate by freezing
the small capillary outlet, so silica gel or molecular sieve is (included and) sealed to absorb
the internal moisture, and install a minute net to eliminate the foreign substance.

※.Influence of moisture
① Moisture precipitation – Blocked by ice
② Refrigerant and reaction
③ Life reduction of oil
④ Acceleration of oxidization
⑤ Copper plating phenomenon
⑥ Gas dissolution by the interaction of synthetic insulating material (insulator)
※.Influence of foreign substance
① Increase of condensed temperature.
② Increase of temperature.
③ Decrease of cooling efficiency
④ Shorten the life by friction between oil and foreign substance in the compressor.
■ Accumulator
1. Role : To send a pure refrigerant gas to compressor by removing completely the refrigerant
liquid from evaporator.
※ If a refrigerant liquid go into the compressor, overload is occurred.

DISASSEMBLY AND REASSEMBLY
• Unplug the refrigerator before cleaning and making repairs.
• Do not dissemble or repair the refrigerator by yourself.
- It may cause risk of causing a fire, malfunction and/or personal injury.
• Remove any foreign matter or dust from the power plug pins.
- Otherwise there is a risk of fire.
• Do not use a cord that shows cracks or abrasion damage along its length or at either end.
• Do not plug several appliances into the same multiple power board. The refrigerator should always be
plugged into its own individual electrical which has a voltage rating that matched the rating plate.
- This provides the best performance and also prevents overloading house wiring circuits, which could
cause a fire hazard from overheated wires.
• Do not install the refrigerator in a damp place or place where it may come in contact with water.
- Deteriorated insulation of electrical parts may cause an electric shock or fire.
• The refrigerator must be grounded.
- You must ground the refrigerator to prevent any power leakages or electric shocks caused by current
leakage from the refrigerator.
• Do not put bottles or glass containers in the freezer.
- When the contents freeze, the glass may break and cause personal injury.
• Do not store volatile or flammable substances in the refrigerator.
- The storage of benzene, thinner, alcohol, ether, LP gas and other such products may cause
explosions.
