A hopeful inventor who has not studied thermodynamics (nor kept up to date with current technology) believes he has created a wonderful device for heating a space. He circulates refrigerant between a cold space and a warm space, using a compressor to move the refrigerant. The cold space is kept at 23°C, whereas the warm space is maintained at 25°C. The inventor believes his system can deliver 50 kW of heat while the system’s compressor uses 1 kW of power. What do you tell the inventor about his proposed system, which he has called a “pump of heat”?
