A group of college students living in a residence find their apartment building's A/C system is broken. It’s extremely hot and uncomfortable. Alex and Ry decide to buy a window A/C unit from Home Depot. They don’t install it in the window; instead, they place it in the center of their living room and turn it on.Meanwhile, Sam and Taylor opt for an even lazier solution: they leave the fridge door open in the kitchen to cool down their apartment.Which of the two solutions is more effective? Do either of them work? Why or why not?(There are no graphs or diagrams in this image.)

principlevof RAC:- Refrigeration and air conditioning systems work on principle that it take energy from the syster(here room) and by means of work input it operatescon cycle and supply that heat to the surrounding(here in bot the case roo. as a surrounding too). suppose it take a Q heat from the room for cool down the room or fridge unit. and applied work on it is W so this system supply Q+W heat to the surrounding (for practical case outside the room). But here, in both the case back side of AC and Refrigeration unit put inside the room. so both unit take Q unit of heat from the room and supply Q+W heat to the room from back side (which suppose to take place outside the room). From above Ultimately in both the case heat will add up in the room (W unit) and room will heat up rather then cool down! so, these ideas are not work to cool the room!

A bunch of residential college students wake up one morning to find that their apartment building's A/C system is down. It is hot and unbearable. Alex and Ry run down to Home Depot and pick up a window unit A/C. Not feeling like bothering to install it in the window, they just put the unit in the middle of their living room and run it. Sam and Taylor, being even lazier than Alex and Ry, decide to just keep the fridge door open in the kitchen to cool the apartment. Is one idea better than the other? Do they work? Why or why not?

11. Five large hotels in Miami, USA, use their own air-conditioning units, which have a c.o.p. 3.1. It is proposed that the cooling systems of the five hotels be substituted with a larger, modern unit that would have a c.o.p. 3.7. The total installed capacity of the five hotels is 2,600 tons of air-conditioning and the current systems are in use for 3,200 hours every year. Determine: a) the annual energy savings from this substitution and b) the annual avoidance of CO₂ emissions if, currently, 72% of the electric energy in the Miami area is obtained from coal power plants and 28% from nuclear power plants.
