23Product Specifications■Evaporator1. Role: As the low pressure liquid refrigerant flowed from capillary absorbs heat insideof the refrigerator, it becomes low pressure gas and refrigerate the foods.2. Theory: The low pressure refrigerant flowed to evaporator operates cooling whichtakes ambient evaporated potential heat with maintaining the evaporation up toevaporate completely.3.Types of EvaporatorA. 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.■Compressor1. Role: It operates same as pump which pull out the subterranean water. It inhales thelow temperature and pressure refrigerant gas (flowed out) from evaporator and makehigh temperature and pressure refrigerant liquid in the compressor and send it to thecondenser.2. Type of Condensera. Back-and-forth motion type: A method that pistol makes back-and-forth motionthrough shaft and cylinder of motor rotation and compresses.※ Used for household refrigerantb. Rotary Type: A method that inhales the refrigerant gas through the gap betweenthe outside of rotor electric attached on the shaft and the inside of cylinder andcompresses.c. Centrifugal Type3. Please insert the explanation of inverter comp operation theory.■Dryer1. Role: Absorb the moisture from the refrigerant that refrigeration cycle circulates andeliminate the foreign substance.2. Structure: If even some moisture is included refrigerant is impossible to circulate byfreezing 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 foreignsubstance.
