1.A Carnot air conditioner keeps the temperature in a house at 297 K on a day where the outside temperature is 311 K. What is the coefficient of performance of this air conditioner? 2.A Carnot engine has an efficiency of 22.0%. It is operating between two reserves at constant temperature that differ by 750C. What is the minimum temperature (TL) and the maximum temperature (TH)?
An Air conditioner maintains a house temperature of 23C while outside temp is 50C. If gbe refrigeration cycle removes 8kw from the house and compressor does 2 hp of work on the refrigerent. determine 1. the heat rejected to the outside environment in kw? 2. the actual coefficient of performance for A/C unit 3. the max possible cop
A window air conditioner uses 1307 W of electricity and has a coefficient of performance of 2.75. For simplicity, let's assume that all of that electrical energy is transformed into work done by the air conditioner to cool a room with dimensions of 7 m x 7 m x 3 m. The air inside this room will initially have the same temperature as the air outside (319 K) and the air conditioner will attempt to cool the room to 295...

= To cool a summer home without using a vapor-compression refrigeration cycle, air is routed through a plastic pipe (k = 0.15 W/m-K, Di -0.15 m, Do-0.17 m) with a smooth interior surface that is submerged in an adjoining body of water. The water temperature is nominally at Too = 17°C, and a convection coefficient of ho- 1500 W/m2K is maintained at the outer surface of the pipe. Air from the home enters the pipe at a...
