Systems and Components Refrigerator

Refrigeration systems work
The system starts working refrigerator compressor as the heart of the refrigerator that serves as the driving force. At the time of electricity, the compressor motor will rotate and put pressure on the cooling agent. Gaseous cooling agent when given gas pressure will be high pressure and temperature. With such a form, allowing refrigerant to flow into the condenser. At the point of condensation, and the gas will condense back into liquid form. High pressure liquid refrigerant will be pushed towards the capillary. With so refrigerant to the evaporator will rise due to capillary pressure which is owned by a capillary tube.
While in the evaporator, the liquid refrigerant will evaporate and his form back into a gas, the pressure and temperature are very low. As a result, the air becomes trapped in the low temperature evaporator and finally condensed into a liquid form. In recurring conditions allow the air freezes into ice granules. This happens on objects or water accidentally placed in the evaporator.

COMPONENT IN REFRIGERATOR:

compressor
Compressor is the most important part in the refrigerator. If the analogy with the human body, the same compressor with a functioning heart pumps blood throughout the body as well as the compressor. Compressor cooling material pump function throughout the refrigerator.
condenser
The condenser is a heat exchanger for cooling the material to change the form of gas at high temperature and pressure into a liquid form. Type of condenser which is widely used in refrigerator technology is currently the air conditioning condenser. Used in the cooling system of small and medium-sized refrigerator. condenser as this has a simple form and does not require special care .Currently working refrigerator condenser will feel warm to the touch.

Filter.
Filter (filter) that may be useful to filter out impurities carried by the flow of coolant out after serkulasi from entering into the supercharger and the capillary. In addition, cooling the material to be routed to the next process is cleaner so it can absorb more heat maximum
evaporator
Evaporator absorbs heat from the object to be put into the fridge, then the evaporator evaporative cooling material to resist heat and cool it. According to its function vaporizer evaporator is cooling agents that are effective in absorbing heat and evaporating cooling material, evaporator made ​​of stainless metal material, ie copper and aluminum.
thermostat
Thermostat has many names such as temperature control and cool control. Whatever the name, the thermostat controls the compressor work automatically based restrictions on any part of the refrigerator temperature. That said, the thermostat is an automatic switch based on temperature settings. If suhau evaperator according to the temperature control thermostat, the thermostat will automatically deciding power to the compressor.
heater
Almost the entire refrigerator nofrost and a small portion is equipped with a refrigerator defrost heater (heater). Heating serves the frost melt contained in evapurator. other than that the heater can prevent frost accumulation on the ice shelf and rack storage of fruit under the ice shelf.
fan motors
Fan motors or fan handy to blow wind. the refrigerator there are two types of fans:

     evaporator fan motors
     Functioning blowing cold air from the evaporator to all parts of the shelf (shelf ice, vegetables, and fruit).
     condenser fan motors
     This fan is placed at the bottom of the fridge which has a small sized condenser which serves to suck or push air through the condenser and compressor. besides that cools the compressor.

The motor overload protector
Is a safety component that is located together with the compressor terminal. The way it works is similar to a fuse that can connect and disconnect electric current. This tool can protect electrical components from damage due to the resulting current flow compressor exceeds the normal reference flows.
Cooling Materials (Refrigerant)
Refrigerant is a substance that is easily changed its form from gas to liquid, or vice versa. Very diverse types of coolants. Each type of cooling agents have different characteristics.
Cooling Material Requirements (Refrigerant):

     Non-toxic, colorless and odorless
     Not including flammable materials.
     Not cause corrosive
     Can be mixed with lubricating oil compressor
     Has a chemical structure that is stable
     Has a low boiling point
     Have a low condensation pressure
     Has a low evaporation rate
     Have a low latent heat
     Having a relatively cheap price.
