Air conditioners sold in the United States are given a seasonal energy-efficiency ratio (SEERSEER) rating that consumers can use to compare different models. A SEERSEER rating is the ratio of heat pumped to energy input, similar to a COPCOP but using English units, so a higher SEERSEER rating means a more efficient model. You can determine the COPCOP of an air conditioner by dividing the SEERSEER rating by 3.4. Required:
For typical inside and outside temperatures when you'd be using air conditioning, estimate the theoretical maximum SEER rating if an air conditioner.

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
