Engineering

A refrigerator in a laboratory uses R-22 as the working substance. The high pressure is 1200 kPa, the low pressure is 201 kPa, and the compressor is reversible. It should remove 500 W from a specimen currently at -20°C (not equal to T in the cycle) that is inside the refrigerated space. Find the cycle COP and the electrical power required.
