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?

Question
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?
