The table below describes two devices which were installed to study the 2nd law of thermodynamics. Both devices have different purposes and serve different types of climates. a. Identify which of the devices is a refrigerator and a heat pump. Justify your decision. b. Evaluate the power input to Device A, in kW. Given that the coefficient of performance (COP) of Device A, is 15% of a reversible cycle. c. Assess the minimum power required (in kW) to drive Device B if the outside temperature is 0C during the winter. Given that the rate of heat transter to or from the room is 7,000kJ/hr per degree Celsius temperature difference between the inside and outside air d. For the same power found in part (c), determine the maximum outside temperature to maintain the room at 23C during summer
