The condenser This component is supplied with high-temperature high-pressure, vaporized refrigerant coming off the compressor. The condenser removes heat from the hot refrigerant vapor gas vapor until it condenses into a saturated liquid state, a.k.a. condensation.
How does refrigerant go from gas to liquid?
When the Freon gas is compressed, its pressure rises, making it very hot. Next, the hot Freon gas moves through a series of coils, which has the effect of lowering its heat and converting it to liquid. The Freon liquid then flows through an expansion valve, which causes it to cool down until it evaporates.
What component is used to control the flow of liquid refrigerant?
Flow control device (expansion valve): This controls the flow of the liquid refrigerant into the evaporator. Control devices usually are thermostatic, meaning that they are responsive to the temperature of the refrigerant.
When a refrigerant changes from liquid to vapor in the evaporator the result is?
Vehicle refrigeration The refrigerant now passes into the evaporator as a mixture of liquid and vapour, its temperature being lowered to something like −10°C with a corresponding pressure of 2 bar (under these conditions the refrigerant will boil in the evaporator).
What are the 4 main components in a refrigeration system?
The refrigeration cycle contains four major components: the compressor, condenser, expansion device, and evaporator.
What are the four stages of refrigeration?
The compressor, condenser, expansion valve, and throttle valve are part of the Vapor Compression Refrigeration Cycle. The aim of the compression process is to raise the pressure in the air.
Is refrigerant liquid or gas?
The refrigerant, a chemical compound that changes easily from liquid to a gas. When the refrigerant is pushed into the compressor, it is a low pressure gas.
What is the state of refrigerant leaving the evaporator?
gas
The refrigerant leaves the evaporator as a warm, saturated low pressure gas.
When does the refrigerant change from liquid to vapor?
It continues until the refrigerant has absorbed enough heat to complete the change from liquid to vapor. As long as the refrigerant is boiling, it will remain at a constant temperature; this temperature is referred to as saturation temperature or evaporator temperature. As soon as the refrigerant is done boiling, the temperature starts to rise.
When does flash gas occur in a refrigerant system?
Flash gas happens spontaneously when the condensed liquid is subject to boiling. The more flash gas in the system the less liquid refrigerant there is to absorb the heat. In turn reduces the efficiency of the system. 21. Quality means when referring to a refrigerant.
How does a condenser affect the refrigerant cycle?
So, a condenser decreases the pressure of the refrigerant, which then causes the temperature to decrease. And a refrigerant getting colder means that the air around will be getting warmer. In an air conditioner, the condenser expels hot air — air that has stolen its energy from the refrigerant.
Where does high pressure liquid refrigerant flow from?
High pressure subcooled liquid refrigerant at a typical temperature and pressure of 30°C and 10 bar respectively flows from the receiver to the expansion valve via the sight glass and drier.
