A refrigerator uses refrigerant-134a as the working fluid and follows the ideal vapor-compression refrigeration cycle with a non isentropic compressor. The refrigerant enters the evaporator at 120 kPa with a quality of 34 percent and leaves the compressor at 70°C. The compressor consumes 600 W of power. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
