Hint: Carnot engines run in a cycle and are reversible. The exchanging of heat takes place at temperature source and at sink temperature. Generally Carnot engine absorbs heat from the higher temperature reservoir and releases heat at lower temperature reservoir and produces the amount of work done.
Complete Solution :
- In the question it is asked what the main feature of Carnot refrigeration cycle is.
- Leonard Carnot proposed a theoretical cycle related to the Carnot engine.
- There are four processes involved in Carnot cycle : isothermal expansion, isothermal compression, adiabatic expansion and adiabatic compression.
-The above mentioned all four processes are reversible.
- Generally the Carnot refrigeration cycle absorbs the heat from the lower temperature reservoir by using external work done and delivers the absorbed heat to the higher temperature reservoir.
- Carnot refrigeration cycle and Carnot heat engine are one of the Carnot cycle applications.
- Means the main feature of Carnot refrigeration cycle is to accomplish the reverse effect of the heat engine.
So, the correct answer is “Option A”.
Note: Carnot heat engine absorbs heat from higher reservoir and releases at low temperature reservoir but Carnot refrigeration cycle does in reverse, absorbs heat at lower temperature reservoir and releases heat at high temperature reservoir.
