Why is this AC rated in tons?

I presume you're asking about an air conditioner.\n\nAir conditioners are rated in terms of the equivalent cooling capacity of tons of ice.   So, a one ton air conditioner can cool as much as a ton (2000 lbs) of ice melting in a 24 hour period.   A home air conditioning unit is typically in the range of 1-3 tons of capacity.  One ton is also equivalent to about 12000 BTUs (British Thermal Units) per hour of cooling.

your question does not make sense. I think you have a program running, or your CPU is getting hot. If it's too hot, that's why the fans are running, and you may have a lot of applications running, or you may have dust. DO NOT USE A LEAFBLOWER!!! \n\nIt can bend all the transistors and electronic to bend. Use a C02 can that compresses the air, it's much more gentler.

Air conditioning?  Well I don't really know much about this stuff but it sounds pretty cool...

The air temperature within the casing being higher than the shaft bearings is a result of compression of the air in addition to the heat generated by turbulence. You are also paying for the energy to heat this air, hence the more efficient the blower, the cheaper it is to run.\n\nYou don't mention what type of blower you are using. Assuming you are using a 'squirrel cage' type blower, some turbulence, with it's associated noise and heat, can be eliminated by adjusting the gap between the squirrel cage and the entrance to the blower's discharge opening. The smaller this gap, the more air is discharged, instead of tumbling back into the blower housing.\n\nI  have had luck with some books written by Dave Gingery, primarily the one titled "How to design and build centrifugal fans". I've listed the website below. \n\nHope this helps\n\nOuzinki

It looks like it can run to 90°C under load without problem\nhttp://users.erols.com/chare/elec.htm\nThis link may give you some tips, but I don't think you have a serious problem...\nhttp://www.hardwaresecrets.com/article/143

Don't forget to choose the best answer.\nWe are real people answering real questions with real answers so please show your appreciation by choosing the best answer!\n\nMr. Cummings owns an air conditioning repair and installation company in Gig Harbor, Washington (United States). Gig Harbor is near Fort Lewis - a major military installation.\n\nHe has an unsatisfactory record with the Better Business Bureau (BBB), based on the fact that there have eight complaints to the BBB in the last 3 years, of which five were ignored. The company is not a member of the BBB.\n\nA Nick D. from Puyallup, WA rate the company highly in a review saying, "I will definately be going here again! These guys are experts with A/C hardware and know how to get the job done right the first time! This is the best place to go if you have any questions about A/C as well! It's tough to find guys like these in the HVAC arena. I have had them help me a few times with projects and they have never failed me!"\n\nHe is apparently a Republican (donated $300 to the National Republican Congressional Comittee in 2003). \n\n\nHTH,\n\nJennyinJamaica

I can be expensive, depending on how much you want.  It usually runs about 2.3-2.4g/dollar.  The problem is most companies only sell it in bulk quantities.  You're looking at close to $200 for a bulk purchase of 450g.  It's not worth it.

Call your supplier and ask.  Though I doubt it is anywhere near as cold as it gets where you are otherwise it is not what people would use to heat their homes.

next time turn the airconditioner on...............or if you did....then may be ur partner i a bit too much heavyweight for ya...lolz

TOO MUCH.  And it limits mobility.  They are working on lightening the load, but no matter what they do, it'll still have weight and bulk.

Most house circuits are rated at 15 amps and the units you have found that list 115 volts, 15 amps are likely designed for such circuits.  That said, you must consider the total amps of other loads on the same circuit which may serve several other wall outlets, etc.  It is not a good idea to run other major units such as TV's or refrigerators on the same circuit serving your air conditioner.  Perhaps you can share the circuit with a clock or small lamp.  The air conditioner may draw maximum amps only during startup of the compressor (you can hear it groan).  If the circuit trips, shed other loads.  Avoid using extension chords for the air conditioner (even heavy duty chords increase voltage drop at the plugs).  One neighbor discovered that his house voltage was often lower than it should be and the power company added a booster for him.  Low voltage draws more current (amps).  A qualified electrician may be able to upgrade your circuit to 20 amps, depending on the house wiring, to avoid trips.  Good luck.

Probably some connection pooling happening somewhere. Don't worry about it, it'll get dropped or reused if required.

The general rule of thumb in the Deep South of the USA is 1 ton of AC for every 600 square feet of space with an 8-10ft ceiling.\n\nYour room has a volume of 86.8 cubic meters.\n\n1 cubic meters = 35.3146667 cubic feet\n\nso your volume is 3065.25 cubic feet.\n\n1 ton is recommended for 600 sq.ft X 10ft = 6000 cubic feet.\n\nSince you have about half of that then 1/2 ton would probably do the trick.  A ton = 12,000 BTUH so 1/2 ton = 6000ft.\n\nI would recommend you get 9000BTUH to help handle the extra load from no insulation and the excessive temperature rise.  Since you don't have to worry about humidity in the desert, then oversizing the A/C shouldn't be a problem as it would be in a place with high humidity.\n\nGood luck!

first of all, 120/240 are standard voltages for AC power, not DC.  DC comes in all flavors.\n\nanyway: 2500 kilowatts DC?\n\nthat is 2.5 MEGAwatts.  \n\ni find this somehow hard to swallow.  when i worked at a particle accelerator there was ONE really big DC power supply that put out something like 1.5 megawatts.  it was the size of a small apartment, and required massive amounts of water cooling, was entirely custom built, and probably cost something on the order of a million dollars or more.\n\ni don't think there is any such thing as "usual" for a 2.5 megawatt power supply.  think about it - you're talking about nearly the power consumption of a small town.  anything liek that would have to be custom built.\n\n----\n\nok, having seen your additional details:\n\ni'm quite positive it's AC, not DC.  it also probably depends on what kind of generator it is.  to give you a rough estimate, here's an example of a 11.5MW turbodiesel generator on a cruise ship:\nhttp://www.ship-technology.com/projects/destiny/\nnote the output is at 6.6kV.  that would set the current at the output at around 1.8 amperes.  \n\nhere's some more information.  as you can see there is no real "usual".  \nhttp://www.ship-technology.com/contractors/electrical/abb2/\n\ncheers!

I think it has something to do with the excess air trapped inside of it.

The ground conductor is a safety feature ...\n\nMost people plug a device into an AC outlet without everthinking about how it works. Most of the time, everything works fine and no problems are experienced. However, there are a few things that are helpful to know about AC power as far as disc jockeys are concerned.\n\nThe "power" that is supplied by a typical wall socket is 120 volts AC (often written as VAC). AC is an abbreviation for alternating current. In addition, some outlets are wired for 240 VAC (these are typically used for devices requiring a large amount of power, such as electric ranges, dryers, etc.). Devices requiring 240 VAC power have different plugs as compared with devices intended for "standard" household outlets.\n\nThere are two common types of power, single phase and three phase. Most disc jockeys will never have to deal with three phase power directly. There is virtually no equipment that a DJ will ever have to use that requires three phase power, as it is used only where very large amounts of power are required. Three phase power will be briefly discussed below. Since the vast majority of equipment that a mobile DJ uses runs off of standard 120 VAC, it will be the focus of these discussions.\n\nAll power outlets have a current rating, the most common ones being 15 amperes and 20 amperes (amperes is almost always abbreviated to amps). The amp rating of an outlet specifies the maximum amount of current that may be drawn from the outlet without tripping a circuit breaker (or, in older systems, blowing a fuse). The primary reason for circuit breakers and fuses is to limit the amount of current that may bedrawn. If too much current is drawn through a wire, overheating of the conductors may occur, leading to a possible fire.\n\nThe amount of power that may be safely drawn from an outlet is the product of the voltage and the current rating, and the units are watts. For 15 and 20 amp circuits (assuming 120 VAC), the power ratings are 1800 and 2400 watts, respectively. The total power draw of the devices connected to an outlet should not exceed these values (or else the circuit breaker may trip). \n\nWhat are the three "prongs" for?\nYou may have noticed that many appliances, tools and most pieces of professional audio gear have a cord with 3 prongs on the plug. The power outlet of course has 3 corresponding female receptacles (unless it is an older type,which has only two slots).\n\nThe longest, often rounded prong is the ground conductor; the primary purpose for this conductor is for safety. There is also a hot conductor, and a neutral (or sometimes called return) conductor. On a wall outlet, the wide slot is connected to the neutral conductor, and the narrow slot is connected to the hot conductor (the ground conductor is connected to the "half round"hole). On some cords with a ground prong, the hot and neutral prongs are often the same width. Most 2-prong cords today are polarized; one prong is wider than the other (allowing it to be plugged in only one way). You should never defeat polarized cords, they are made that way for a reason! Also, note that in 120 VAC wiring, the black wire is the hot wire! (often, black is used for ground in DC electronics). The hot and neutral conductors are the ones that actually carry the power to and from the device of interest.\n\nThe hot conductor is so called because it is the conductor that actually has the voltage on it. The hot conductor has 120 VAC on itwith respect to the neutral conductor. The voltage on the hot conductor is of nopractical use without the neutral conductor, because for useful work to be done current must flow through a device; the neutral conductor provides the path to complete the circuit. Ever wonder why birds can sit on power lines (at thousands of volts) without getting shocked? Despite the high voltage on the line, no current flows through the bird since there is no return path conductor. The reason for elec
