8-1. REFRIGERATION CYCLE
COMPRESSOR:
CONDENSER:
DRYER:
Capillary tube:
Evaporator:
HEAT EXCHANGE BETWEEN SUCTION TUBE AND CAPILLARY TUBE:
THERMOSTAT:
STARTING RELAY:
OVERLOAD PROTECTOR:
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.
Mounted inside the refrigerator to regulate the temperature of refrigerator.
When motor starts running owing to sub winding interrupts of current simultaneously.
When circuit is overheated, it is cut off to prevent compressor wind burn-out.
