What is air conditioner ton

Ton as the name suggests is equivalent to 1000 kg. How is this related to air conditioner? Actually room air conditioners were derived from the technology used to refrigerate ice or to convert water to ice in earlier times. To relate ice and cooling capacity a formula is derived which says the amount of energy required per hour to make one ton of ice in twenty-four hours.

This comes out to be 12000 BTU (British thermal units).

So one ton is equal to 12000 BTU.

Cooling capacity of an air conditioner is measured in tons so one ton AC provides 12000 BTU in one hour.

How much ton AC is suitable for your room

The cooling of a room also depends on other factors other than ton like, insulation, number of windows, sunlight, heat producing appliances in the room like TV, computer etc.

A simple calculation is as follows

Multiply the length, breadth and height of the room (take units as feet). Then divide this by 1000 to get the ton capacity

Example if the room’s size is 10 feet by 10 feet by 10 feet

So 10 X 10 X 10 comes out to 1000, divide this by 1000 the answer comes to 1. So your as tonnage requirement is one ton

Another example room size 12 feet by 12 feet by 9 feet. The multiplication comes out to be 1290. Dividing this by 1000 leads to 1.2. so tonnage requirement is 1.2 ton. If there is direct sunlight in the room and  /or the air conditioner is exposed to sun, or you stay on the top floor where roof heats up, go for 1.5 tom AC otherwise go for 1 ton AC as air conditioners are available in 0.75 ton. 1 ton and 2 ton and above capacity only

    what is 1 ton ac power consumption

  • Neha

    what is 1.5 ton AC power consumption

    • living advisor

      1.5 ton AC should consume between 1700 watts to 1800 watts. This translates into 1.8 units per hour. If unit rate is Rs 5 it will cost Rs 9 per hour to run the AC.
      If you keep the thermostat setting above 24 degrees you will save more electricity as the compressor will switch off more often as you increase the temperature and in the compressor switched off mode the AC will consune only 180 to 250 Watts to run the fan motor only.
      A high rated 5 star AC will consume less power and low end 1 star ac will consume more power. But in window AC you will get BEE star rating upto 3 stars only

    • AMIR NAWAB

      1.5 ton ac consuption 1800 Watts per hour and 1 ton 1400 Watts per hour

  • madhukar

    what is the power unit consumption (Rs 5 per unit) of 1.5 ton 5 start LG AC with the thermostat setting 26 degree?

  • living advisor

    Power consumption depends upon the time the compressor of the AC is on. This depends on various factors like: room size, outdoor temperature, room insulation, no of people in the room and heat producing gadgets in the room like TV and lastly the thermostat settings.
    For every degree increase in thermostat setting you save upto 5% energy. 26 degree is a good setting. Always use ceiling fan along with the AC as you feel cooler even at highet temperature settings.

    straight answer to your question

    The time compressor is on it will consume about 1.7 units an hour that comes to RS 8.50 an hour. When compressor is off and only AC fan is running it will consume about 0.2 units an hour that translates to Rs 1 an hour. If your compressor is on for 50% of the time and you run the AC for 8 hours at night the power conumption will be 7.6 units or Rs 38 per night

  • Y K

    Dear Advisor,

    My bedroom is 15*15*10,Since room is on first floor, suggest me I sholud go for window ac or split ac

    According to the above calculation minimum tonnage req is 2.0 ton, but it will consume more electricity

    so could you suggest me which company’s 1.5 ton ac will efficiently work in my that room?

    • living advisor

      2 ton ac will consume more power that is OK but it will switch off when the room becomes cooler. The 1.5 ton AC will have to work more hard to do so and it may not switch off and run continously which may damage it. The power consumption will be the same. If you keep the room temperature above 25 degree celcius then only 1.5 tom AC will be beneficial to some extent. 2 Ton ac is suggested as it will switch off when the set temperature is reached

    • DANIEL SINGH

      Y.K- 1.2 Ton is more than sufficent for your room. I suggest you go for 5 star rated a/c. This way you make little more investment upfront, that will however save you electricity bills over the life of your A/c. according to one study, 5 Star rated a/c will save around Rs. 10,000 in 5 yrs. Based on my research Hitachi a/c are the best, in terms of technology and efficency.

    According to the above calculation minimum tonnage req is 1.5 ton, but it will consume more electricity

    so could you suggest me which company’s 1 ton ac will efficiently work in my that room? & what is the power unit consumption (Rs 6.5 per unit) of 1.5 ton 5 start voltas AC with the thermostat setting 25 degree?

    • living advisor

      Go for 2 ton ac. The five computers wil generate heat so the five people using it. The more the people and heat generating equipment in the room the more the requirement of air conditioner. Do not go go for 1 ton AC as it will not be able to meet your requirements. Minimum 1.5 ton AC is required

  • Shrey

    How much power does the a 1 ton and 1.5 ton AC consume at the time of start up. I have heard that it takes double the power to start, is it true?
    Thanks

    • living advisor

      Yes it is true that AC takes double the power to Start. So it is advised to switch on the airconditioners one by one if you have more than one AC in your house. Most air conditioners now come with a random timer to switch on to facilitate this.

    • living advisor

      Panasonic is a very good AC. Air conditioning depends upon many factors like, outdoor temperature, room insulation, number of doors and windows and the like. 1.5 ton AC is suggested for 12*12*9 room.

  • sachin

    1ton ac how much kw

  • Mohd Zahid

    1 Ton ac’s consume about 1300 watts which is 1.3 units per hour. if your ac runs for 10 hours a day with compressor running 70% of the total runtime then it would run for 7hrs. Now consider the billing per unit say INR 5.0 then the total cost would be 7*1.3*5 = INR 45.5/day (in energy saver mode). For a month it would be 45.5*30 = INR 1365/month.

  • Anand

    Almost all reply posted above are technically wrong:

    1 Ton AC current consumption 6 amp. Voltage 220 V the power consumption is VI 220*6= 1320 watts i.e. 1.32 units per hour

    1.5 Ton Ac current consumption 10 amp. Voltage 220V the power consumption is VI 220*10=2200 watts i.e. 2.2 units per hour

  • dogendra

    what is the power consumption per hour (per hour unit consumption)of 1T airconditioning system (centralised)for voltas & blue star make ?

    • living advisor

      The consumption will be around 1.3 units per hour if the ac compressor is on all the time. The compressor switches on and off depending on outside and inside temperature and its settings, so actual consumption will be less.

  • Shaikh

    Pls let me know that, Can split a/c capable to pump cool air from a outside space which is 27 or 30 meters away to interior.

    • MANOJ KUMAR

      It is depending upon the capacity of AC, like more capacity above 5.0 ton is possible for cooling 85 to 95% from its actual capacity its maintain to calculated by chenged the dia of suction & discharge pipe of the connecting unit and some top up of refrigerant gas 35 gram per ton above 35 ft but its opposite under 5.0 tr is not efficient to represent actual cooling cause compressor has not able to pump properly because absent of compressor oil in crankcase during when unit is running all oil moved in copper pipe with refrigerant so compressor head is too hot & system is function abnormal its create very high in summer time so it is first desided to choose the efficient capacity of AC.

    I am planning to buy an Inverter Split AC in Bangalore for my bedroom (L=12, B=10, Height=9.5 ft). One wall of room is West facing with an open balcony in which I have 4*4 ft sliding glass window and also a wooden door of 7*3.5 ft.

    Room is on 3rd floor and have one more floor above.

    Room has lots of furniture; king size bed with 2 side tables, dresser, entertainment unit with 32′ LED TV, baby crib. Room is occupied by 2 adults and 1.5 year old infant.

    I have shortlisted Daikin brand but confused between 0.75 Ton or 1 Ton models. Technicians who inspected site said both are fine, some say 0.75 is enough some say take 1 Ton to be on safe side. Checking AC tonnage calculators online some suggest 0.75 while others 1 Ton, some put it in between.

    Both have pros and cons; I think 0.75 Ton will consume less power but with temperatures soaring in Bangalore, heard it will reach 40 degrees this April, I am not sure if its correct in longer run. I am unable to take a right call, there is Rs.6K difference between 2 models.

    Please help urgently, quick response if much appreciated!!

    )

    • living advisor

      Inverter AC is new technology introduced but it is costly and requires power supply with less fluctuations. The tonnage is variable in Inverter AC as compared to fixed tonnage but the difference does not converts to more savings in electricity bills. Setting room temperature at 26-27 degree Celsius as compared to 22-23 Celsius will save more power (about 30%)

      As room is bigger 1.5 ton AC will be better. Power consumption will be the same. 1.5 ton AC will obtain the set temperature earlier and will shut off while 1 Tom AC will take a long time to coll. So more or less the power consumption will be the same. Added advantage is the room will get cooler faster.

      You can same more power by setting the room temperature at 25-26 degrees than setting it at 22-23 degrees. So the suggestion go for 1.5 tom AC and save power by setting temperature suitably.

  • Anurag

    Dear Munish,
    I have checked out various split AC brands available in the market but lil bit fuzzy about which AC to go for. I need to know which 1.5 ton provides value for money between Lloyd, HItachi, panasonic, daikin and Mistubishi.
    Kindly do reply asap.
    Cheers,
    Anurag.

    • All product brands mentioned by you are good. Go for energy efficient AC based on star rating and having copper coils. The more you think the more you get confused due to presence of many brands and models.
