Refrigerators currently being manufactured in the United States are using______as their refrigerant.
QI Two reservoirs 727 °C and 23 °C are used to operate heat engine. 50% from the power output of heat engine is employed to drive a reversed Carnot refrigerator that absorbs heat from the cooled space at -2 °C at a rate of 6.7 Kw and rejects heat to the surrounding at 200 °C. Calculate the rate of heat supplied to the heat engine.
The refrigeration system of a food production firm is run using the Reversed Carnot Cycle. The temperature of the hot refrigerant supply in the system should be 52°C, while the temperature of the sink should be -14°C. Its capacity is projected to be at least 24 tons. It's important not to disregard losses. Find and Show unit analysis and conversion: a. COP and COP of Heat Pump b. Heat rejected from the system in kW c. Network in, Hp and Energy Efficiency Ratio
A certain refrigerator has a COP of 5.00. When the refrigerator is running, its power input is 500 W. A sample of water of mass 500 g and temperature 20.0°C is placed in the freezer compartment. Assume all other parts of the refrigerator stay at the same temperature and there is no leakage of energy from the exterior, so the operation of the refrigerator results only in energy being extracted from the water. -->Compare the cost to make 44 kg of ice using two different refrigerators; one has a COP of 5.00 and the other has a COP of 6.00. Electricity costs $0.10 per kWh. Using the same assumptions given in the example, find the cost difference (in dollars) between the refrigerators to freeze the water.
