SUMMARY
The discussion centers on the thermodynamic cycle of a refrigerator as described in "Heat and Thermodynamics" by Zemansky. It is established that in this cycle, the heat absorbed from the hot reservoir (|Q_H|) is greater than the heat expelled to the cold reservoir (|Q_L|), leading to a negative value for |Q_L| - |Q_H|. Consequently, this value cannot equal the work done (|W|) in the cycle, confirming the initial assertion as incorrect.
