An existing steady state refrigerator has been operating using the vapor-compression cycle for some months, with a COP of 3.1. Today the rate at which work is being added to the compressor is the same, but QC has decreased. Which of the following statements must be true? a. The new COP must be higher. b. QH must be larger in magnitude than normal. c. QH must be smaller in magnitude than normal. d. The compressor efficiency is lower than normal.
