What tonnage is my carrier unit? Find the model number. Within this string of letters and numerals, you should find an even, two-digit number. The possibilities on residential units range from 18 to 60. Divide the number by 12 (which represents 12,000 Btu
British thermal unit
The British thermal unit (BTU or Btu) is a traditional unit of work equal to about 1055 joules. It is the amount of work needed to raise the temperature of one pound of water by one degree Fahrenheit (Physical analogue: one four-inch wooden kitchen match consumed completely generates approximately 1 BTU). In science, the joule, the SI unit of energy, has largely replaced the BTU.
How do you find the tonnage of a carrier air conditioner?
How do you find the tonnage of a Carrier AC unit? The possibilities on residential units range from 18 to 60. Divide the number by 12 (which represents 12,000 Btu/hr, or one ton of cooling capacity) to get your AC unit's tonnage.
What is the tonnage of an AC unit?
Tonnage is a measure of BTU’s in 12,000 BTU increments. A ton of air conditioning equals 12,000 BTU. Residential air conditioners usually range from 1.5 to 5 tons (or, 18,000 – 60,000 BTUh).
What is “tonnage” in HVAC?
It’s the amount of heat needed to raise the temperature of one pound of water by one degree. The word “tonnage” is used to describe the cooling capacity of an air conditioner. One ton of cooling is the rate of heat transfer needed to freeze 2,000 lbs – or one ton – of water in 24 hours. This is equivalent to 12,000 Btu/hr.
How do I find out what model my carrier unit is?
The model and serial number can be found on the rating plate of your air conditioner or heat pump. This is generally found slightly above the refrigerant valves on the back side of the unit. Also Know, how do I find out what year my carrier unit is?
Carrier Model Number Location
Finding the model number off of your Carrier air conditioner can be very simple if you have a new unit. Start by looking the model number in your owner’s manual book or any other paperwork that came with your unit. Be careful, as this sometimes can result in incorrect parts.
How to Decode Carrier Model Number
When it comes to Carrier model number breakdown, you must be very careful. Carrier has many common style of model and/or serial number. Take a look at our example below:
Why is an undersized air conditioner bad?
Of course, an undersized unit is also problematic because it can’t keep up on the hottest summer days.
What is a BTU?
One Btu is equivalent to the heat generated by a single birthday candle. It’s the amount of heat needed to raise the temperature of one pound of water by one degree. The word “tonnage” is used to describe the cooling capacity of an air conditioner.
What is AC tonnage
BTU (British Thermal Units) is the term used to measure the heating and cooling capacities of an air conditioner. A single Btu is equal to the heat produced by one birthday cake candle.
What is AC tonnage per square foot
AC tonnage per square foot is the term used to measure an area that can be cooled by an air conditioner. This is necessary to calculate before making a decision.
How AC tonnage is calculated
You can get a general idea by the fact that you will need 1 tonnage air conditioner for 600 sq ft place. This is a general estimation but there are formulas that can help you to calculate exact AC tonnage.
What tonnage of AC do I need
The answer to this question can easily be taken by calculating the square foot area of the room and then deciding the best suitable AC for that area. While the area corresponding to the AC tonnage has been mentioned above in the table, you can do a general estimation by calculating the area first and then multiplying the value with 20.
How to calculate AC tonnage for a room
Although all the methods and ways to calculate AC tonnage for a room have been briefly described, you can get it done with a simple method as well. The method also starts with taking the area and then moving forward.
How many kilowatts does a 3 ton ac unit use
In normal conditions, a 3-ton air conditioner unit uses from 3000 to 3500 watts per hour. Some ACs may use less or a bit high watts depending on the brand or varying weather conditions. The normal range of AC tonnage and their kilowatts usage of energy is as:
Thumb rule for AC tonnage calculation
The thumb rule of AC tonnage calculation is just to take the area by L * W * H of the room and then divide the value by 1,000. This will directly give you the required tonnage for the room. Suppose you have a room of 10 * 10 * 10:
