wat is meant by tonnage of a airconditioner capacity??

Domestic and commercial refrigerators may be rated in kJ/s, or Btu/h of cooling. Commercial refrigerators are mostly rated in tons of refrigeration. One ton of refrigeration capacity can freeze one short ton of water at 0 °C (32 °F) in 24 hours. Based on that:\n\nLatent heat of ice (i.e., heat of fusion) ≈ 144 Btu / lb (or 334.5 kJ/kg) \nOne short ton = 2000 lb \nHeat to be extracted = 2000 * 144 = 288000 Btu / 24 hours = 12000 Btu/hour = 200 Btu / Minute \n1 ton refrigeration = 200 Btu / minute = 3.517 kJ/s = 3.517 kilowatts[8] \nA much less common definition is: 1 tonne of refrigeration is the rate of heat removal required to freeze a metric ton (i.e., 1000 kg) of water at 0 °C in 24 hours. Based on the heat of fusion being 334.5 kJ/kg, 1 tonne of refrigeration = 13,938 kJ/h = 3.872 kW. As can be seen, 1 tonne of refrigeration is 10% larger than 1 ton of refrigeration.\n\nMost residential air conditioning units range in capacity from about 1 to 5 tons of refrigeration.

Dear u should first tell your requirements which capacity of diesel genrator u r lookig for ?

The amount of air is the difference in volumes.\nA = V(r+1) - V(r) = (4/3)pi (r+1)^3 - (4/3)pi r^3\nA = (4/3)pi((r+1)^3 - r^3)

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

Want to see something neat??\n\nType "19 gallons in cubic feet." into google.\n\nWorks for all kinds of conversions.

It includes the number of air handlers being used, and the use of each room.  For example, equipment rooms have specific cooling requirements.  Generally, it depends on the total build-up area.

Its bound into a CloroFloroCarbons used in the "Freons"\n\nThe Freons are special molicules that are realitivly safe (Unless your an Ozone layer) and have BOILING points below the temprature you want to achieve.  Basicly There is a pump inside a air conditioner that compresses the gas until it becomes liquid where it gives off its heat *feel the back side of an air conditioner* then it goes through a tiny little tube and boils inside the tubes on the front side of the air conditioner *the one on the back is called a condenser, the one on the Front is called a evaporator based on if the freon is condensing or evaporating in it*

good question...the term air conditioning refers to conditioning of air..irrespective of outside temp..i.e. when u want to cool ur room in hot climate and heat ur room in cold climate...\nrefer the site: www.marineengineering.org.uk     and go to main page and select utilities and the refrigeration and air conditioning systems both diagram and formulaes...

Since m*C*dT=Q;\n\nHeat capacity=135000 J/(5100 g*(31.5K - 18K))= 1.96 J/gK\n\n(K for Kelvin)

You need to do a heat load calculation on your house to determine your heating and cooling needs. Then you size your heat pump equipment. where ever you get the equipment from should be able to tell you diameter and length of tube. You need to decide how much room you have for the installation. If your room is unlimited go with larger tube and 2 pipe system. What type of soil do you have? You can save some time and effort by using different installation methods.

It is now clear who is asking for the limit of 3 degrees. Is it the turbine manufacturer, surface condenser manufacturer, or someone else?\n\nI assume the condensate is being pumped. Is it the condensate manufacturer that is asking for the limit?\n\nI would think from a heat conservation standpoint, you would want to keep it as close to the condensing temperature as possible and still be able to pump the condensate.

density of pure water is 62.4 lbs/sq ft.\n\nSo, load = dAgh\n\nor A = 40000/(62.4*5*32) = 4.01 sq ft.

The word ton or tonne is derived from the Old English tunne, and ultimately from the Old French tonne, and referred originally to a large cask with a capacity of 252 wine gallons, which holds approximately 2100 pounds of water. Such a barrel (of any similar volume) is still called a tun in British English, but this usage is dying out.
