pressurized water nuclear reactor steam power plant has many examples of open system operation.Some of these are the pressure vessel,steam generator,turbine,condenser,and pumps.45A coal fired steam power plant as a heat engine operating in a thermodynamic cycle.Photo courtesy of Progress Energy Carolinas,Inc.6Photo courtesy of Progress Energy Carolinas,Inc.7Heat Pump SystemsA typical heat pump system is shown here.In the heating mode high pressure vapor refrigerant is sent to the indoor heat exchanger coil.The refrigerant gives up its energy to the inside air and condenses to a liquid.The liquid is throttled to a low pressure and temperature to the outdoor coil and receives energy from the from the outside air.The refrigerant vaporizes,enters the compressor to be compressed to the high pressure,and the cycle is completed.8Spark ignition internal combustion engine9Two stage(two pistons)7.5 horse power compressor with intercooling attached to an eighty gallonThe heat exchanger shown here is typical of liquid-to-gas heat exchangers.In this case hot coolant from an 1966 Mustang engine flows into and out of the heat exchanger through the inlet and exit tubes.Air from the passenger compartment is heated as it flows through the fins.10Photos Courtesy of APV Heat Exchanger Product Group11A hair drier is an example of a one entrance,one exit open system that receives electrical work input to drive the fan and power the resistance heater.1213Photo courtesy of Progress Energy Carolinas,Inc.Compressor blades in a ground station gas turbine 14Shown here are the compressor and turbine stages of an industrial gas turbine under repair.The compressor has eighteen stages of compression and the turbine has three stage of expansion.Photo courtesy of Progress Energy Carolinas,Inc.CompressorTurbine15Throttle or expansion tube.Throttle may be a simple as the expansion tube used in automobile air conditioning systems to cause the refrigerant pressure drop between the exit of the condenser and the inlet to the evaporator.16One stage of a two-stage,intercooled refrigerant compressor in a chilled water refrigeration system17Typical shell and tube heat exchanger used for the intercooler,evaporator,and condenser for a chilled water refrigeration system.18Forced draft cooling tower for cooling water used in the intercooler and condenser heat exchangers of the chilled water refrigeration system19Honey comb like structure inside forced draft cooling tower to cause better mixing of the cooling water and air.20Another application of intercooling to reduce compressor work is shown here as a two-stage,7.5 hp air compressor with intercooling.First stage piston with second stage piston in backIntercooling heat exchangerDrive wheel spokes function as fan
