Work done in cycle of a refrigerator (in Heat and Thermodynamics by Zemansky)

[MatinSAR]

TL;DR Summary

I caanot understand what is happnening in chapter 6 part 7. The book has two equations for work done in cycle of a refrigerator

I guess the first one is wrong.
Because in this cycle we have ##|Q_H| > |Q_L|## then ## |Q_L| - |Q_H| ## is negative and caanot be equal with ##|W|##.

Am I right?

Yes.
