I wanted to know that why the word ton is used in measuring the capacity of the airconditioner, why the word ton is only used for aircontioner not for any other appliance
how the word ton was decided to be used while the word aircondition or the product was invented.
what is the formula of calculating the tonage, what is EER, BTU.

Re: why the word ton used for airconditioner.
this what i found for you...
The unit ton is used in refrigeration and air conditioning to measure heat absorption. Prior to the introduction of mechanical refrigeration, cooling was accomplished by delivering ice. Installing one ton of refrigeration replaced the daily delivery of one ton of ice.
In the United States, a standard ton of refrigeration = 12,000 BTU/h = 200 BTU/min ≈ 3,517 W. It is approximately the power required to cool 1 short ton of water by 1 °F every 10 minutes; or the power required to melt one short ton (2,000 lb) of ice at 0 °C in 24 hours.
A ton is also a unit of energy equal to that power for a period of a day, or 24 h × 12,000 BTU/h = 288,000 BTU ≈ 303.9 megajoules.
A less common usage is the power required to cool 1 long ton of water by 1 °F every 10 minutes = 13,440 BTU/h ≈ 3,939 W.
All the Best.

Ton is a measure of cooling only when buildings were cooled by ice and how many tons of ice they would use in 24 hours.
British Thermal Units (BTU's) is also a measure of cooling as well as heating in 1 hour.
1 ton equals 12,000 BTU/hr and 1 watt equals to 3.41214 BTU/hr.
If you no longer have the manual that came with it, you can always measure the dimensions internally and do the math to calculate the cu ft capacity. Do do this multiply all the measurements together. Then write that down. Take and multiple 12*12*12 and write that number down. Take first number and devide second by it. That should tell you the cu ft capacity of your oven or whatever you want to determine.
Hi, I am not sure what you are wanting to know? If you want to know the size of the a/c tonnage wise, its 5,000 b t u's short of being a 1 ton unit. There is 12,000 b t u's of cooling per each ton. 2 tons would be 24,000 b t u's, 30, a 2 1/2 ton unit and so on. If this is not what you needed to know, please get back to me and let me know.

Are you referring a to an electric furnace providing the heat, the heat pump providing the heat, a heat pump providing heat usually with an auxillary/emergency electric heating unit, or an air conditioner with an electric furnace attached? If your system normally uses a heat pump for the heat normally, there is an eletric auxilliary heater. You'll probably need to turn it on at the thermostat manually when the outside temp gets below 40 degrees. If you have it nice system, it might do it automatically. If you're referring to the electric heater being rated 8 kw, it'll run using 8kw when you turn it on. It doesn't have the ability to change what heat rating it is. If you're refurring to the heat pump system being rated 8kw, you're probably mistaken. A heat pump might possibly consume 8kw to run the system but that can't be a measure of the system's capacity. Heat pump measurement units are rated in tons, but the system will always run at the same ton capacity whenever it's on, provided it doesn't need any maintenance. Some commercial air conditioning and heating systems have to ability to modify their power output based on the outside temperature, but I doubt you're dealing with that kind of thing.
I have a 3 ton a/c system that removes about 5-6 gallons of water from the air per day. Most portable dehumidifiers/air-conditioners rate at approx 1/2 to 3/4 of a ton. Your water output is pretty much normal.
