Draw a schematic representation of a refrigerator.

(N/A) refrigerator is a heat pump that extracts heat from a cold reservoir and rejects it into a hot reservoir by performing external work.
Schematic representation:
$1$. $T_H$ (Hot reservoir/Surroundings)
$2$. $Q_H$ (Heat rejected to surroundings)
$3$. $W$ (Work done by the compressor)
$4$. $T_L$ (Cold reservoir/Inside the refrigerator)
$5$. $Q_L$ (Heat extracted from the cold reservoir)
The cycle is represented as:
$Q_L + W = Q_H$
Diagram description:
- $A$ box labeled $T_L$ (Cold reservoir) releases $Q_L$ energy to the system.
- The system performs work $W$ on the refrigerant.
- The system releases $Q_H$ energy to the box labeled $T_H$ (Hot reservoir),where $T_H > T_L$.
