Homework Help: Schroeder, Thermal Physics: impossible refrigerator?

  1. Apr 4, 2010 #1
    1. The problem statement, all variables and given/known data
    Schroeder, Thermal Physics, p.129, Problem 4.12:
    2. Relevant equations
    COP = Qc/W

    3. The attempt at a solution
    I honestly have no idea why it shouldn't be possible. As for the COP, I get COP = cp/R * Pmin/[tex]\Delta[/tex]P + cv/R * Vmax/[tex]\Delta[/tex]V but not that it really matters, I think. It must a conceptual solution, I just have no clue...

    All help appreciated,
    Thank you
