The use of tons to measure cooling capacity comes from this time. A ton refers to the amount of heat it takes to completely melt a ton of ice. The capacity of an air conditioner refers to the amount of heat it can remove. Rounding up 11,917 Btu/hr gives you 12,000 Btu/hr, which is one ton of air conditioner capacity.
How do I calculate what size air conditioner I need?
To calculate the size of the air conditioner you need for a room, first, multiply the length of the room with its width. Then multiply it with 25 BTU to get the ample cooling for the room under different weather conditions. For example, if the room is 15 feet long and 12 feet wide, it comes to 180 square feet.
Why is it called 1 ton AC?
A ton is used to describe how much heat is removing from a room in 1 hour. In earlier times, natural ice is used to cool a room. So, the cooling we get in a room with 1 ton of ice in 24 hours is called as ton of refrigeration.
What does 3 ton air conditioner mean?
‘ One ton means the rate of heat transfer needed to freeze one ton of water in 24 hours. This is equivalent to 12,000 Btu/hr. So, a 3-ton AC for instance, does not actually weigh 3 tons. It means that it has a nominal capacity of 36,000 Btu/hr.
What is the meaning of 12000 BTU?
A Btu is the amount of heat necessary to raise the temperature of 1 pound (0.45 kilograms) of water one degree Fahrenheit (0.56 degrees Celsius). One Btu equals 1,055 joules. In heating and cooling terms, one ton equals 12,000 Btu. A typical window air conditioner might be rated at 10,000 Btu.
What size air conditioner do I need for 50 square meters?
Small shops and offices also are typically in the 45 to 50-square metre range. In this case, the best capacity is seven to eight kW. For bedrooms, small kitchens, and lounges that are 10 square metres, a 2.6kW air conditioning unit will suit them.
What size air conditioner do I need for a 2000 square foot home?
Step 5: Match your square footage to an HVAC size chart Home Sq Footage Air Conditioner Size (tons) 600 – 1,000 square feet 1.5 tons 1,000 – 1,500 square feet 2 tons 1,500 – 2,000 square feet 3 tons 2,000 – 2,500 square feet 4 tons.
How do I know if my AC is 1.5 ton?
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/hr, or one ton of cooling capacity) to get your AC unit’s tonnage.
What is COP in refrigeration?
Coefficient of Performance The COP is determined by the ratio between energy usage of the compressor and the amount of useful cooling at the evaporator (for a refrigeration instalation) or useful heat extracted from the condensor (for a heat pump). A high COP value represents a high efficiency.
How many BTU is 600 square feet?
Answer: Using the EPA’s 20 BTU per sq ft rule of thumb, the room size of 12,000 BTU air conditioners is 600 sq ft. Equally, 1 ton AC room size is about 600 sq ft. Again, when narrowing down your choice of an air conditioner, knowing how big an area you need to cool is your best friend.
Can you replace a 2 ton AC unit with a 3 ton?
Simple answer: yes. But that really depends on the size of you house and its condition. If the 2 ton unit is working as designed but seems to run continuously without satisfying the thermostat setting, then it might be undersized and replacing it with a 3 ton unit might be the answer.
How many sq ft will a 3 ton AC unit cool?
3-ton is equal to 36,000 BTU. If you apply the 20 BTU per sq ft rule of thumb, you can see that a 3-ton air conditioner cools about 1,800 square feet spaces.
Is 2.5 ton AC big enough?
According to this common but somewhat inaccurate method, you need 1 ton of air cooling capacity for every so many square feet of living space. While there’s some dispute over the exact amount, an often-used amount is 600 square feet. A 2.5-ton unit, then, theoretically would fit a 1,500-square-foot home.
How many sq ft will 18000 BTU cool?
BTU Sizing Chart for Mini Split Systems Area To Be Cooled Capacity Needed (BTUs Per Hour) 450 to 550 square feet 12,000 BTUs 550 to 700 square feet 14,000 BTUs 700 to 1,000 square feet 18,000 BTUs 1,000 to 1,200 square feet 21,000 BTUs.
