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:
A. ROLL-BOND Evaporator --> Direct Cooling ONE-DOOR Type
☞
Rolled and adhere the 2 aluminum plate and then make refrigerant passage.
B. FIN-PIPE Evaporator
⇡
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
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 (rotation axis) and the inside of cylinder and compresses.
C. Centrifugal Type
2. Product Specifications
2-8. Operation theory of refrigeration cycle components
