A refrigeration system operates with a COP of 3. If the refrigerating effect is 1200 J, what is the work input required for the system?
💡 Hint: Use the formula of COP to relate refrigerating effect and work input.
If a Bell-Coleman Cycle refrigerator must lower the temperature of the air from 300K to 270K, considering it's working at a consistent pressure of 1 atm, determine the refrigerating effect produced.
💡 Hint: Remember to analyze the cycle and compute based on temperature changes and properties of air.
