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.ac unit barely blowing air Power Consumption and cooling capacity. air conditioner window unit 10 000 btuWhich one determines the value I am interested in? 1 ton window air conditioner prices in pakistanFor 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\% \$. It should be fine.Browse other questions tagged power ac generator or ask your own question.Written On average AC will consume 1205 Watts per hour when Temperature is set at 25 degree CelsiusThe AC's power consumption depends on its star ratingListed below is the BEE star rating chartThe EER is calculated by the following formulaCOP = amount of heat removed in W/ power consumed in WEvery 1 ton of cooling power (commonly known as heat removed by a 1 ton AC in one hour) is also expressed as 3500 wattsHence 1.5 ton AC will be rated

at at least 5275 WattsWe can calculate input wattage using the above chart for various star ratingsThus if 5 star split ac with 1.5 tons cooling capacity is rated for 1507 watts it will consume 1507 watts per hour1000 watts per hour is one unit of power consumedThus the AC will consume 1.507 units per hourIn real life usage AC compressor will run for only 70 percent of time normally. But since you are using Ac @ 4 degree Celsius above recommended Temperature the compressor will run 80 percent of the timeThus on average AC will consume only 1205 WattsThe AC will consume 1.205 Units in an HourAssuming eight hours usage per day it will consume 9.64 units per dayAC power consumption in a month (30 days) will be 290 units approximately14 percent increased power as compared to usage @ 24 degree CelsiusYou can apply the above calculation for any AC - but only for non inverter ACsIdeally the Ac must be run at around 25 degree CelsiusPlease refer to below links for more info on energy efficiencyVivek Ravindranath's answer to How can I use the air conditioner in an environment-friendly manner?

Be the coolest !!!Refrigeration tons (RT) to kilowatts (kW) power conversion calculator and how to convert. Enter the power in tons and press the Convert button: kW to tons conversion One refrigeration ton is equal to 3.5168525 kilowatts: 1 RT = 3.5168525 kW One kilowatt is equal to 0.284345 refrigeration ton: 1 kW = 0.28434517 RT So the power P in kilowatts (kW) is equal to the power P in refrigeration tons (RT) times 3.5168525: P(kW) = P(RT) × 3.5168525 Convert 2 RT to kilowatts: P(kW) = 2 RT × 3.5168525 = 7.033705 kW kW to tons conversion ►Written A 1.5 ton ac generally uses 1.5 to 2 kW for its operation, which means upto 2 units per hour if operated continously. But within a 10 hour period it would consume much less than the predictable value of 20 units (2 units*10 hours). This is because the compressor is not ON all the time. The Compressor runs and does the cooling to specified levels and then turns off until the temperature drops again.

so taking the duty as 70%. it would consume 10 to 14 units in the given scenario. Kindly note that the actual power consumption is dependent many other factors like Usage Mode, Temperature Settings, Maintenance of the Unit.Written now as asked,first check your ac ratings.as your ac is 1.5 ton then it consume 1499 w/hr.you house voltage is 240v.then current taken by ac is 1499/240=6.25A.and as different tariff u will be charged 5/6/7/8 rupey per unit as per your residential.Written The AC's power consumption depends on its star ratingListed below is the BEE star rating chartThe EER is calculated by the following formulaEER= amount of heat removed in W/ power consumed in WEvery 1 ton of cooling power (commonly known as heat removed by a 1 ton AC in one hour) is also expressed as 3516 wattsHence 1.0 ton AC will be rated at at least 3516 WattsA 5 star AC will have a EER of at least 3.5 according to BEE guidelinesHence input power wattage = Heat removed (watts) / 3.5Hence input wattage rating = 3516/3.5 = 1005 watts (5 star rating)Ratings for various Star ratings1 star - 1302 Watts2 star - 1212 Watts3 star - 1134 Watts4 star - 1065 WattsThus if 5 star split ac with 1 tons cooling capacity is rated for 3516 Watts, it will consume 1005 watts per hour1000 watts per hour is one unit of power consumedThus the AC will consume 1.005 units per hourBut compressor runs only
