Question

What is the reverse Carnot cycle?

Answer 1

Reverse Carnot Cycle

1. The mechanism of a refrigerator or heat pump is an example of the reversed Carnot cycle.
2. The contrary of the Carnot cycle happens at reversed carnot cycle.
3. In this cycle user supplies work to a pump, it extracts heat from the low-temperature source and pumps it to the high-temperature sink.

The efficiency of the reverse Carnot cycle

1. The efficiency of the reversed Carnot cycle is the ratio of the heat removed from the cold reservoir to the amount of work input.
2. Efficiency, $\eta =\frac{Q_1}{W}$

Where$Q_1=$ the heat removed from the source (cold reservoir)

$W=Q_2-Q_1=$Amount of work input.

$Q_2=$Heat pumps to the sink
