Condenser 1) Role: A device which radiates heat to the outside of the refrigerator. As this heat is dispersed, the high temperature/ high pressure vapor refrigerant changes to a liquid state. 2) Types A. Air-cooling Air-cooling Type Type : Condense air by circulating naturally or or manually. manually. 1) Natural Convection Type : Used for the household refrigerator which has small condensing capacity. (No Fan) 2) Manual Convection Type : Circulate air manually by FAN-Mo FAN-Motor tor (Large capacity) B. Water-cooling Water-cooling Type : Make Make cooling water pass through through the pipe in the condenser (Large capacity)
Location 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. product. (An old model) model) Install the condenser on the outside of the product. product and radiate heat manually by fan. Make them cluster at the lower part of product Radiate condensed potential heat up to liquefy completely and make change the state without changing the gas temperature itself. Pipe thickness Low pressure: pressure: 6.3mm 6.3mm High pressure : 4.7mm Capillary : About 0.4-0.8mm Condenser length (Based on 300ℓ): 26.5 M Assistance : 5 M HOT HOT-PIPE: -PIPE: 6.6 M CLUSTER-PIPE: 4.17 M Capillary 1. Ro Role: le: A device which makes low temperature temperature and pressure pressure refrigerant 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 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.

Evaporator 1. Role: As the low pressure pressure liquid refrigerant flowed from capillary absorbs heat heat inside of the refrigerator, it becomes low pressure gas and refrigerate the foods. 2. Theory: The low pressure refrigerant flowed to evaporator evaporator operates cooling which takes ambient evaporated potential heat with maintaining the evaporation up to evaporate completely. 3.Types of Evapora Evaporator tor A. ROLL-BOND Evaporator Direct Cooling ONE-DOOR Type
Rolled and adhere the 2 aluminum plate and then make refrigerant passage. B. PIN-PI PIN-PIPE PE 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 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 Condens Condenser er 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 comp operation theory.
Dryer 1. Role: Absorb the moisture from from the refrigerant that refrigeration cycle circulates and eliminate the foreign substance. 2. Structure: If even some moisture 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 Moisture precipitation - Blocked by ice Refrigerant and reaction Life reduction of oil Acceleration of oxidization Copper plating phenomenon Gas dissolution by the interaction of synthetic insulating material (insulator) . Influence of foreign substance Increase of condensed temperature. Increase of temperature. Decrease of cooling efficiency Shorten the life by friction between oil and foreign substance in the compressor. Accumulator 1. Role : To To send a pure pure refrigerant gas to compressor by removing completely completely the refrigerant liquid from evaporator.

• Unplug the refrigerator before cleaning and making repairs. • 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 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, ether, LP gas and other such products may cause explosions.

Reference Value
1) For example, if you want to change freezer compartment standard temperature to -4 -4(-2°C) by operating option, do as below. This function is for changing the standard temperature. In -2 -2(-19°C) of current temperature of freezer compartment, if you make the temperature lower t o -4 (-2°C) by the option, the st andard temperature would be controlled -6 -6 (-21°C) Therefore, if you change the setting of temperature option to -2 -2 (-19°C) on the panel, the appliance will be operated with -6 -6-21°C). -21°C). It means that standard temperature is controlled -4 -4 (-2°C) less than setting temperature in the display.
NOTE
Basically, all the data in option has cleared from the factory. Therefore, almost all setting value are "0". But, some setting values could be c hanged for the purpose of improving performmance. You Y ou need to check the product manual and/or specification.
2) After changing to the option mode, fresh food compartment "0" , freezer compartment "0" will be displayed. ( Basically fresh food compartment "0", freezer "0" would be set at shipping process, but sett ing value could be changed for the purpose of improving product product at mass producing process.) - If fresh food compartment "0" shows only, temperature reference value of freezer compartment will be set and current freezer compartment temperature code will be displayed on the freezer temperature display. 3) If freezer compartment "4" is set as below freezer compartment code after fresh food compartment "0 is set, standard temperature of freezer compartment will be lower than -4 -4(-2.0°C). (Refer to the picture "changing the freezer c ompartment temperature")
Code
Reference Value
: If you wait for 20 seconds after completing the setting, MICOM will save the setting value to the EEPROM and normal display will be returned and the option sett ing mode will be canceled. 4) Option changing method as above is t he same. 5) By the same method as above, it is possible to control the fresh food compartment temperature, water supply, ice-maker harvest temperature/time, defrost return time, hysteresis by temperature, notch gap by temperature etc. 6) Option function is set in the EEPROM at shipping process in the factory. You Yo u would better not to change the option of your own. Completing the setting is that option function return to normal display after 20 seconds. Do not turn off the appliance before returning to the normal display mode.
NOTE
Option setting function exists in the other items. We will skip the explanation of the other functions by the option because it is associated with refrigerator control function and is not needed at SERVICE. (Please do not set the other options except above SERVICE Manual.) 55
