Which thermodynamics process is present in refrigerator?
The convection is the most present process in the refrigeration equipment you may deal with. It occurs mainly in the fluids (Liquids and Gas). It is the result of a fluid circulation, which can happen either naturally, due to differences on the temperature of the fluid, or forced way.
What is refrigeration system in thermodynamics?
Refrigeration systems operate on a series of consecutive thermodynamic processes that form a cycle that returns the working substance to the same state. A thermodynamic refrigeration cycle removes heat from a low-temperature object (refrigeration) and rejects it at a higher temperature.
How does refrigeration system work?
The refrigerant flows into the Compressor where it is compressed and pressurised. At this point, the refrigerant is a hot gas. The refrigerant is then pushed to the Condenser which turns the vapour into liquid and absorbs some of the heat. As the gas cools down the load, it absorbs the heat which turns it into a gas.
How does a refrigerator reflect the Second Law of Thermodynamics?
How does a refrigerator reflect the second law of thermodynamics? The thermodynamic changes in a refrigerator are not spontaneous, and the entropy of the system and surroundings increases.
How does a refrigerator work chemistry?
The refrigerator works by using a cycle of compression and expansion on the Freon. Work is done on the Freon by a compressor, and the Freon releases heat to the air outside of the refrigerator (as it undergoes the exothermic condensation from a gas to a liquid).
What does a refrigerant do?
A refrigerant is chemical compound that is used as the heat carrier, which changes from gas to liquid and then back to gas in the refrigeration cycle. Refrigerants are used primarily in refrigerators/freezers, air-conditioning, and fire suppression systems.
What is a refrigerator in physics?
A refrigerator is a heat engine in which work is done on a refrigerant substance in order to collect energy from a cold region and exhaust it in a higher temperature region, thereby further cooling the cold region.
What Law does a refrigerator work?
Refrigeration works on one of the corollary of second law of thermodynamics namely clausius statement. Which states that heat can’t be continuously transferred from low temperature reserviour to high temperature reserviour without using some external work.
What cycle does a refrigerator work on?
Air cycle refrigeration works on Reversed Carnot cycle and Bell Coleman cycle. Air is compressed and then heat removed, this air is then expanded to a lower temperature than before it was compressed. .
