Do air conditioner and refrigerators work on joule Thomson effect or adiabatic cooling? Elaborate differences between these two processes. They both look the same
Homework Answers
Air conditioner or Refrigerator works on adiabatic cooling
Difference between Adiabatic cooling and Joule Thomson effect......
1. In Adiabatic cooling, dQ=0
Whereas, in Joule Thomson effect,dH=0..i.e. the process is isoenthalpic
2. Adiabatic cooling process may be reversible or irreversible
Whereas joule Thomson effect is highly irreversible

QUESTION 1 [15 marks] Due: 5 August 2020 An air conditioner operating at steady state takes in moist air at 28°C, 1 atm and 70% relative humidity. The moist air first passes over a cooling coil in the dehumidifier unit and some water vapor is condensed. The rate of heat transfer between the moist air and the cooling coil is 38.69 kW. Both saturated moist air and condensate streams exit the dehumidifier unit at the same temperature. The moist air...

LEARN MORE REMARKS In this problem, we didn't address the effect of possible differences in the helghts of the pistons. If the column of fluid is higher in the small piston, the fluid weight assists in supporting the car, reducing the necessary applied force. If the column of fluid is higher in the large piston, both the car and the extra fluid must be supported, so additional applied force is required. QUESTION if the radius of the output piston is...

Norwegian Air Shuttle Aspires to Become the Cheapest Global Airline It’s snowing in Copenhagen as Norwegian Air Shuttle Flight DY7041 lifts off. There are nearly 30 passengers on board, most of them Norwegians, Swedes, and Danes eager to escape the gloom that engulfs their part of the world in late November. Today they will arrive in Florida faster than usual. This is the first direct flight from Scandinavia to Fort Lauderdale. And it’s a bargain: The tickets are a fraction...
