How much square footage does a 1-ton air conditioner cool? For very hot climates, a 1-ton air conditioner can cool approximately 400 square feet, but in cooler climates, the same air conditioner could cool 800 square feet. The cooling capacity of an air conditioner is greatly dependent upon the temperature of the environment in which it is installed. How many square feet does a 5,000 BTU air conditioner cool? How do you determine the size of air conditioner needed in a space? Homes that are insulated extremely well can use smaller systems. Homeowners should be careful to avoid getting larger air conditioning units than are really necessary because they could actually cool living spaces too quickly and not allow the humidity to be released. High humidity will still feel uncomfortable even if the air temperature is lower. How do you determine the appropriate number of BTUs an air conditioner should have? The number of British thermal units necessary in an air conditioner is determined in part by the square footage of the space to be cooled.

Where is the reset button on an oil furnace? Who makes aircraft air conditioning units?Written Possibly, but it depends greatly upon the temperature differential you want to hold between the outside and the inside, and the thermal resistance (insulation properties) of the walls doors and windows.E.g. if the wall are too thin you could never hold a 10 degree differential even.In hot humid areas like the south central US a temperature differential might be as much as 40 degrees F. (22 degrees C).Your best bet is to contact a HVAC specialist or look at the recommendations of the company selling the unit.Written First off, it depends on the volume of the room not the area of the room.Information is given in this link below including a table, go through it, please!How to calculate how much ton AC will be suitable for a roomWritten Written While all other answers are absolutely correct and the selection of "tonnage" of an AC machine depends on a number of factors, the rule of thumb is:Select (by minimum), 1 ton per 100 sqft of floor area of the room with normal roof height (9' to 11').

It turns out that for the 144 sqft room with 10' roof height, 1 door, max 2 windows you need 1.44 ton say 1.5 ton.Before, buying it, call an expert to visit the room and decide the tonnage for you :)Written There are other variables to consider before the question can be answeredIs the ceiling exposed to direct sunlightHow many walls get direct sunlight?diy ac repair helpHow many glass windows do you have and how much area is glass covered?hvac heat pump systemWhich city the AC is used?how much does a ac unit weighUse link at bottom of this page to calculate exact needsAir conditioner selection: understand Tonnage, EER, COP and Star RatingSummary of ideal room size for 1.5 ton AC is is as followsIf you are on top floor 130 sq feet (max)If you are on top floor and more than 1 wall receives direct sunlight120 sq feet (max)If you are not on Top floor

, One or less walls receive direct sunlight140 sq feet (max)If you are not on Top floor , Two or more walls receive direct sunlight130 sq feet (max)The above calculations are assuming 10 feet high ceiling.Online Tonnage calculator helps you to determine the AC tonnage required for a particular room. Wall thickness - 9 inch, Colling thickness - 6 inch, Room height - 10ft or less, Indoor Temperature - 24~25 deb.

I am planning to purchase a single AC that would operate on my Diesel generator. My Generator is a 5kVA , 8 HP air cooled one. I want to know that If I have to run only one AC on the generator shall I install a 2 Ton Split AC or a 1.5 Ton Split AC?

Also I Want to know the diesel consumption by the generator per hour. closed as off-topic by jippie, Scott Seidman, uint128_t, Daniel Grillo, PeterJ This question appears to be off-topic.

The cooling capacity is not relevant. The power consumed is important, but you also need to know the current. AC motors need more current than the minimum required for the power consumption. You also need to make sure you have the right voltage and whether you need single-phase or three phase. The KVA for a motor that consumes 1438 watts will probably be between 1.7 and 2.6 KVA.

Watts = VA X Power Factor It is customary for engine generator sets to be designed for 0.8 maximum power factor so 5000 VA X 0.8 = 4000 W would be expected. Power Consumption and cooling capacity. Which one determines the value I am interested in? For an Air conditioner of 1.5 ton ,the power consumption is 1438 wattt and cooling capacity is 5,050 W. Your air conditioning unit works on the principle of a "heat pump". In your case electricity is used to drive the pump. According to the rating plate it will consume 1,438 W of energy while pumping 5,050 W of heat. It is common to quote the coefficient of performance (CoP) for heat pumps as \$ \frac {heat~moved}{electrical~input} = \frac {5050}{1438} = 3.5 \$ which is reasonably good. The generator is rated at 5 kVA. For a purely resistive load 1 VA = 1 W but your air-con unit will be an inductive load so we'll need to derate the generator by about 20% when converting to watts. Let's go for 4kW. Your 1438 W AC unit (let's call it 1.5 kW) will load your generator by approximately \$ \frac {1.5~kW}{4~kW} = 38\% \$.
