what is the major difference between A/c and refrigerator?

an air conditioner helps to maintain the room at  ambient conditions suitable for human comfort by monitoring the parameters like humidity,temperature,dust etc where as a refrigerator keeps the temperature within the system lower than that of the surroundings by using 2nd law of thermodynamics.

The compressor of your Refrigerator is not designed to keep cool a large space such as your room. So once you keep it open, the compressor will get overloaded and it will be spoiled. Take care.

They can be both. . .either that or the air conditioning turning on (it blows doors shut as if ppl are there closing them)\n\n\nBy the way, I like your avatar pic. Einstein was a great man of wisdom and innovation.

You have a 1.5 HP AC that is always running and a 2.5 HP AC that trips every 5 min. All things being equal which AC will consume the least power. \n\nAC’s have the compressor and a fan. The compressor consumes most of the power when it is on. I would guess that the difference in power consumption between the two AC fans is fairly close (a fraction of a HP each), which effectively factors the fans out. That leaves the compressors. A 2.5 HP AC will consume 1.7 times more power than the 1.5 HP AC. Therefore, if the 2.5 runs 5 min before trip than the 1.5 should go 8 or 9 min before tripping. If the 1.5 stays on all day then the 2.5 is more economical by far. \n\nPerhaps there is a malfunction either AC.

The difference is big.  With a water cooled chiller, there is a unit located in the building that acts as the driving force to transfer the heat from the building water loop to a secondary loop (condenser water loop).  The second water loop is then run up to a cooling tower usually located on the roof of a building where the heat is then expelled to the atmosphere.  High efficency with these type of devices.\n\nWith an air cooled chiller, there is no secondary water loop, and the primary water loop from the building runs directly up to the roof.  There, the chiller uses the thermodynamic principles of refrigerants to directly remove the heat to the atmosphere.  There is less equipment with this system, but the efficiency is half that of the water cooled systems.\n\nAlso, air cooled chillers are limited in the total size of the cooling system that they can adaquatly handle, where as water cooled chillers can be much much larger.

Electric Resistance heaters consume huge amounts of power and only heat a limited amount of space as compared to other types of heaters. By comparison air conditioners may be 3-5 times more efficient and heat/cool a much larger volume.\nHowever the efficiency of an air conditioner depends on the ambient temperature and the desired temperature. Also not all air conditioners have the option to both heat and cool(mine hapens to be a portable unit that also heats).\n\nExample: I have a resistance heater with a parabolic reflective dish that might heat about a 5ft radius and consumes 1000Watts.  5ft raduis -> area = (pi)r^2 = about 80sq. ft.\n\nI also have a 10,000BTU air conditioner that heats/cools up to 250sq. ft and only consumes 650Watts max.

Because of all the water that gathers on the tray that supports the a/c mechanism. As air is cooled, water condenses from the air and drips down to the bottom where it gathers. Microbes that like cool moist environments will grow there. These microbes can then be introduced into the air and blown into the room.

I assume this refers to a rule of thumb difference of 30deg F between the condensing freon and the ambient air temperature.  This difference is likely with all the freons but could vary with loading of the system and condition of the condenser.  In terms of basic physics it is the heat to be transferred, the heat transfer coefficient and the heat transfer area that determine the temperature difference and it is the temperature and type of  freon that determines its condensing pressure.

I don't know of any specific studies about air conditioning.  However, I do know from experience that evaporative coolers promote the growth of mold and bacteria, due to the humidity they produce.  Mold and bacteria also can grow on the cooler itself.  Air conditioners, due to being more dry, inhibit the growth of mold and bacteria.  Air conditioning also helps keep out pollens and allergens from the outside air.  This can mean fewer lung and sinus infections for allergy and asthma sufferers.\n\nThat's not to say they're automatically more healthy.  Stale air isn't so good for us; we need fresh air circulating.  And, dry air means dry nasal passages and airways, which means they're in less-optimal condition to help us fight off cold, flu, and little infections we encounter.  So, depending on your local climate, and your allergy/asthma situation, air conditioning could be healthier, or it might not be.

A "Split" air conditioner consists of an two main parts (that are connected only by copper tubing with refrigerant in them - hence the name "split"):\n\nPart (1): The condenser that 'dumps' heat from the conditioned space (like a house) to the outdoors (typically).  It is called a condenser because the refrigerant (the liquid/vapor that absorbs and dumps heat) changes state from a vapor to a liquid while transferring heat - it cools down, or 'condenses'.\n\nPart (2): The evaporator 'absorbs' heat from the conditioned space.  It is called an evaporator because the regrigerant evaporates in the process - it goes from a mixed state of liquid and vapor to all vapor.  In the process it cools the conditioned space.\n\nIn addtion to these two main parts is the compressor that compresses the vaporized refrigerant as it comes out of the evaporator and before it goes into the condensor.  It raised the temperature of the vapor without adding heat. It does this by performing 'work' on the vapor.

Your friend is delusional.\n\nA thermometer and two similar rooms is all you'll need - or, just one room and two thermometers. \n\nThe thermometer under the fan will indicate room temperature - say, 70 degrees - the one in front of the Air Conditioner will indicate approx. 38-40 degrees F.\n\nThere's a valid reason why central air conditioners are so prevalent in the hotter portions of our country.

it has more to do with the differant tempatures\nto put a light in the freezer you need to shield it from the frozen tempatures\n\nin the fridge this is nota prob since tempatures are above 32 deg fahrenhiet

<>You have to be more specific.  Are you talking about an electrical condenser, a refrigeration condenser, an air conditioning condenser, or some other kind?

This site offers some basic versions the the main sections of a refrigerator. They are generic but straightforward.\nhttp://www.jimdow.com/jimdow/sales/diagrams/indexdiagrams.htm

gas cools down if it expands suddenly.\n\nsimilar principle is used in AC and refrigerators.

Wow some of these answers are scary.  The air conditioner works by taking heat from inside the room and blowing it outside.  If the air conditioner is completely in the room, then all the heat that it blows outside stays in the room, therefore the temperature stays the same.\nBut...\nAll machines create heat just by running.  Think computers, light bulbs, etc.  Therefore, the temperature will get a little higher.
