8.HOW TO REPLACE MAJOR COMPONENTS
8-1. REFRIGERATION CYCLE
In evaporator liquid refrigerant is so expanded to absorb heat around evaporator that compressor sucts refrigerant in low temperature and low pressure and then compresses it to gaseous refrigerant in high temperature and high pressure which will be discharged to outside.
Gaseous refrigerant in high temperature and in high pressure so radiates evaporation latent heat absorbed from evaporator surrounding during passing through condenser and compression heat due to refrigerant gas compression to surrounding of condenser that refrigerant becomes liquid in high pressure.
In order to prevent that moisture and foreign substances resided inside every parts during refrigeration cycle assembling is so included among refrigerant gas that it chokes the exit of inlet of capillary, dryer has drying substances (molecular sieves) and filter inside it which absorbs or purify them.
Regulates and/or keeps(in specified low)refrigerant flow rate so that maintains constant pressure drop from wire condenser to evaporator.
Liquid referigerant passed through capillary so expand in evaporator that it becomes low temperature and low pressure to absorb heat around evaporator, so that it chills surrounding air and at that time liquid refrigerant becomes gaseous.
| Liquid refrigerant in high temperature passing through capillary tube so changes heat between | |||
| low temperature on suction tube and then more lowers liquid refrigerant temperature at | just | ||
| before expansion so that increases its enthalpy to result big refrigeration efficiency at last. |
| ||
| Refrigerant gas in low temperature passing through suction tube so exchanges heat between | |||
| liguid refrigerant high temperature passing through capillary | that | it becomes more | hith |
| temperature condition and then it becomes compete gaseous so | that | increase compression | |
| efficiency of compressor. |

THERMOSTAT: | Mounted inside the refrigerator to regulate the temperature of refrigerator. |
| ||
STARTING RELAY: | When motor starts running owing to sub winding interrupts of current simultaneously. |
| ||
OVERLOAD PROTECTOR: | When circuit is overheated, it is cut off to prevent compressor wind |
