Homework Statement Air conditioners operate on the same principle as refrigerators. Consider an air conditioner that has 7.00 kg of refrigerant flowing through its circuit each cycle. The refrigerant enters the evaporator coils in phase equilibrium, with 54.0 % of its mass as liquid and the...

I was just pondering the way an air conditioner works, and I have a basic question. When the compressor compresses the gas, how does it change the volume, temperature, and pressure? Using pv=nrt, there does not seem to be a way to figure out what the proportion that temperature and pressure...

Air conditioners operate on the same principle as refrigerators. Consider an air conditioner that has 7.00 kg of refrigerant flowing through its circuit each cycle. The refrigerant enters the evaporator coils in phase equilibrium, with 54.0% of its mass as liquid and the rest as vapor. It flows...

A home is kept cool by an air conditioner. The outside temperature is 311.75K and the interior of the home is 288.55K. If 127kJ/h of heat is removed from the house, what is the minimum power that must be provided to the air-conditioner? answer in kJ/h my work COP = Th / (Th - Tc) = 311.75...

I bought everything I need today at the hardware store to assemble my cooling apparatus from what I have learned from this smart little whippersnapper: http://www.eng.uwaterloo.ca/~gmilburn/ac/ I haven't started working on it yet, but I was wondering about any sort of condensation problems...

I have been trying to learn how home air conditioners work since I had some problems yesterday with my split system. I was reading here: http://www.energyquest.ca.gov/how_it_works/air_conditioner.html This is a stupid question and basic mechanical engineering, but there is something about...

I have 2 places to put air filters on my home system. One is a 16x20x1 at the wall intake and the other is 4ft up the same duct at the unit (16x25x1). The filter in the wall is a pain in the ass to change in comparison to the one at the unit. But, they are both usually dirty at 3 months so I...

I am interested on understanding the unsteady period of functioning of an air conditioner system, with a traditional refrigerant, let's say R-11. Imagine there is a room which initially is at the same temperature than the external one, i.e. T_i(0)=T_e. Just when I switch on the system, the...

One problem that came up for my father and my aunt was that they did not want to work (cleaning my grandfathers garage, he's in a nursing home now :-/) during the summer in the garage. Now i was wondering how feasible is a portable air conditioner? If say, at the 'hot coils', instead of air, you...

Hi there, I have what should be a simple problem, but it's driving me insane. Here's the problem: A Carnot air conditioner maintains the temperature in a house at 290 K on a day when the temperature outside is 315 K. What is the coefficient of performance of the air conditioner? So I...

Hey, sorry if this is slightly off topic but it's the closest forum i could find that might be able to help me answer my question.. A while back i read a page and a little bit of information on it remained behind in my memory. Basically what it stated was 'the simplest form of overunity is an...
