As shown in the figure, an air conditioner operating at steady state maintains a dwelling at 70°F on a day when the outside temperature is 102°F. The rate of heat transfer into the dwelling through the walls and roof is 30,000 Btu/h and the net power input to the air conditioner compressor is 3.4 hp. Inside, 70° F Evaporator 30.000 Btu Refrigerant loop W. Compressor Outside Condonsor mmo Determine the coefficient of performance of the air conditioner. Determine the power input required, in hp, and the coefficient of performance for a reversible air conditioner providing the same cooling effect while operating between the same cold and hot temperatures.

The PV diagram below shows a sequence of processes applied to an ideal gas inside an engine 1. Which process is an isothermal compression? 2. In which process does the pressure increase with constant volume? 3. In which process is workdone on the gas? 4. What is the workdone on the gas by the process DA?

Required information Refrigerant-134a enters the condenser of a steady-flow Carnot refrigerator as a saturated vapor at 65.0 psia, and it leaves with a quality of 0.05. The heat absorption from the refrigerated space takes place at a pressure of 30 psia. Determine the coefficient of performance. (Round the final answer to three decimal places.) The coefficient of performance is

Provide complete solution and detailed diagram.  A refrigerator is to remove heat from the cooled space at a rate of 300 KJ/min to maintain itstemperature at  - 8oC. If the air surrounding the refrigerator is 25oC, determine the minimum powerrequired for this refrigerator? A. 0.263 kw              B. 0.473 kw           C. 0.623 kw     D. 0.984 kw
