Hi there..

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.

Dump truck sizes

A dual axle dump truck (ten wheels) is normally rated at 10 cubic yards (270 cubic feet) load capacity.
A single axle dump truck (six wheels) is normally rated at 5 cubic yards (135 cubic feet) load capacity.
These are volume measures not weight measures.

What is the rule of thumb for computing the capacity of horsepower of air conditioner in terms of area, e.g. square meters

Horsepower does not necessarily matter. Horsepower is not computed to capacity. Amounts of btu/ heat removal, is measured capacity. 12,000btus which equals 1 ton of cooling will cool a maximum of 500 sqft depending on the heat load. Obviously a brand new home with updated insulation vs a closed in lanai with a wall of get the idea

What is the cubic ft capacity of this old model

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. Sincerely,

One horsepower is how many ton? I want to know how many tons of refrigerant is equivalent to one horsepower capacity of a cooling system.

1 to 1...
1 hp. equals 1 ton or 12,000 BTU' least in round numbers...
this can vary just a bit depending on the combination of condensers and evaporators...

NewAir AirConditioner on "Dehumidifier" Mode Only

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.
