The compressor is the heart of the refrigeration system. The compressor acts as the pump that moves the refrigerant through the system. Temperature sensors start the compressor's action. Refrigeration systems cool objects through repeated refrigeration cycles. Before we proceed, here are some terms that you should know. Compressor: The compressor is the pump that enables the flow of the refrigerant. The compressor works by increasing the pressure and temperature of the vaporized refrigerant.
There are different types of compressors for refrigeration applications. Reciprocating, rotary, and centrifugal compressors are the most common among refrigeration units. Condenser: The condenser is a set of coiled tubes. In the domestic refrigerator, you will find your compressor at the back of the appliance. The condenser cools the vaporized refrigerant turning it back to liquid.
Evaporator: The evaporator is the cooling component of the refrigeration system. It absorbs heat from the contents within the cooling appliance. In the domestic refrigerator, the evaporator is in your freezing compartment. Expansion Valve: This device controls the flow of the liquid refrigerant. The expansion valve is thermostatic. It responds to the temperature that you set. The refrigerant flows from the evaporator coil through the compressor.
This flow raises the pressure of the coolant. When the compressor is activated, an audible humming noise usually can be heard coming from the refrigerator, while there usually is silence when the compressor is not active.
Cooling inside the freezer or refrigerator occurs only if the freezer compressor is running properly. A refrigerator or freezer operates by passing a gas that is hot and under high pressure through a sequence of coils located on the back of the unit until it starts to cool. Once cooled, the gas condenses into a liquid and is passed through a pressure valve that reduces the amount of pressure it is under, immediately causing it to boil and return to a gaseous state and reducing its temperature dramatically.
The cooled gas is then passed through another set of coils inside the freezer compartment that draws heat out of the compartment and into the gas, which continues to cool as it loses pressure.
