  • A reverse heat engine does work to move heat energy from a hot body to a cold body.
  • It is the same as a normal heat engine but the heat energy transferred does not do work, it needs work.

Coefficient of performance

  • The coefficient of performance of a reverse heat engine is like its efficiency.
    • COP=QcWCOP= \frac{{Q_c}}{W}
  • Where QcQ_c is the heat from the cold reservoir.
