How do you calculate 1 ton of refrigeration?
One ton of refrigeration is equal to 3024 kilo-calories per hour. This is 12,000 BTU/ h divided by 2.204 (pounds per kilogram) divided by 1.8 (°C to °F). Most residential air conditioning units range in capacity from about 1 to 5 tons of refrigeration or 3.5 kW ~ 17.5 kW, or 12,000 Btu/h ~ 60,000 Btu/h.
How many KW is a 3 ton AC?
Please share if you found this tool useful:Conversions Table2 Tons Of Air Conditioning to Kilowatts = 7.00880 Tons Of Air Conditioning to Kilowatts = 280.323 Tons Of Air Conditioning to Kilowatts = 10.51290 Tons Of Air Conditioning to Kilowatts = 315.3613 more rows
How do you calculate CFM from motor kW?
If we want to calculate the CFM (Cubic Feet per Minute) for a 4 cycle motor we can multiply the cubic inch displacement of the engine by the maximum rpm (Revolutions Per Minute) and divide the result by 3456. Then we multiply the results by the volumetric efficiency of the motor.
How many watts does a 4 ton AC unit use?
If you have a 4-ton (40-Amp, 48,000 BTUs) air conditioner, you need at least a 17 KW generator. If you have a 5-ton (50-Amp, 60,000 BTUs) air conditioner, you need at least a 20 KW generator.
How many kW is in a ton?
3.5169 kilowattsConversion Ton to Kilowatt The ton (ton of refrigeration) is a unit of power. This tool converts tons to kilowatts (ton to kw) and vice versa. 1 ton ≈ 3.5169 kilowatts. The user must fill one of the two fields and the conversion will become automatically.
How many kW is a 2 ton air conditioner?
7034 wattsResidential central air systems are usually from 1 to 5 tons (3 to 20 kilowatts (kW)) in capacity. So 2 tons of air conditioning would be 7034 watts.
What is kW in refrigeration?
Cooling capacity is the measure of a cooling system’s ability to remove heat. The SI unit is watt (W). Another unit common in non-metric regions or sectors is the ton of refrigeration, which describes the amount of water at freezing temperature that can be frozen in 24 hours, equivalent to 3.5 kW or 12,000 BTU/h.
How do you convert CFM to kW?
Conversion chart – atmosphere cubic feet / minute to kilowatts atmosphere cubic foot per minute to kilowatts = 0.048 kW. atmosphere cubic feet / minute to kilowatts = 0.096 kW. atmosphere cubic feet / minute to kilowatts = 0.14 kW. atmosphere cubic feet / minute to kilowatts = 0.19 kW.More items…
What is the 1 ton of refrigeration?
A refrigeration ton is approximately equivalent to 12,000 BTU/h or 3.5 kW. Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in “tons” (of refrigeration). Many manufacturers also specify capacity in BTU/h, especially when specifying the performance of smaller equipment.
How do I calculate cfm?
Start with the total volume of air (in cubic feet), divide by the exchange rate (how quickly you want to replace the air), and the result is the total CFM you need for your system. Keep in mind that many applications (especially large areas) use more than one fan/blower.
Why is AC rated in tons not in kw?
Refrigeration and air-conditioned (AC) systems are always rated in Tons. Air conditioners are rated in Tons capacity instead of kW or kVA rating because Air conditioners are designed on the basis of quantity of heat removal from room, hall or specific area.
How much power does a 2.5 ton AC use?
I would base it off that to start with, but you must also consider the indoor blower unit which is probably 120V and 3-7 Amps…for 2.5 ton my guess is 3.5-4.5 Amps. So overall your looking at say 30 Amps. Volts x Amps = Watts. Outdoor unit is roughly 5200-6000 watts running, starting is usually rated at 125% of that.
How many kilowatts does a 5 ton AC use?
SO A 5 TON AC WOULD BE AROUND . 1.1 KW/TON X 5 TON = 5.5 KW ( 1 kw consumed electricity in per hour = 1 unit .
How many amps does a 4 ton AC draw?

How many kW is a 4 ton AC?
Central Air-Conditioners use on average 1-kilowatt hour (kWh) per ton per hour. A 4-ton air-conditioner will use approximately 4 kWh per hour.
How do you calculate kW for refrigeration?
Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. We add 273.15K to the celcius to convert it to units of Kelvin. The Specific heat capacity (Cp) is measured in units of kJ per kg per Kelvin. This gives us a final answer of Q = 2,500kW of cooling.
How many horsepower is a cfm?
Rules of thumb: A good single-stage compressor, per true HP input, will deliver about 4 true CFM at 100 psig. It is not uncommon to see this more like 3 CFM per HP.
