Which outcome occurs when a refrigeration heat pump cycle utilizes an inefficient compressor?

💡 Explanation

A less efficient compressor increases the work input required for the same heat transfer due to internal losses during compression. This decreases a refrigerators Coefficient of Performance (COP) because COP is the desired cooling effect divided by the required work input, rather than the system performance, and altering the external energy supplied effects COP, therefore lowering overall efficiency.
