How many BTUs per hour is a ton?

There’s a complicated mathematical formula involved in converting the weight of that ice into energy, but in the end a “ton” of air conditioning capacity represents roughly 12,000 BTU per hour. So a 2-ton unit has 24,000 BTU/hr capacity and a 3-ton has 36,000 BTU/hr, and so on.

Which is equal to 12000 BTU per hour?

A ton of refrigeration is approximately equal to 12,000 BTU/h or 3.5 kW.

How do you convert Btu hr to tons?

1. 1 ton is equal to 12,000 BTUs.
2. 1 Ton = 12,000 BTU.
3. Tons x 12,000 = Number of BTUs.
4. Number of BTUs / 12,000 = Tons.

How many BTUs is 4 tons?

A 4 ton air conditioner is one that can remove 48,000 BTUs of heat per hour from the house. For most people, though, 4 tons means 8000 pounds. (A BTU is a British Thermal Unit, approximately the amount of heat you get from burning one kitchen match all the way down.)

What is meant by 1 ton AC?

What Does the Term “AC Tonnage” Mean? In the HVAC field, a ton, or tonnage, refers to the cooling capacity of an air conditioner. … One ton of air conditioning can remove 12,000 BTUs of heat each hour.

How many BTUs is a 2 ton air conditioner?

A two-ton air conditioner removes 24,000 BTUs per hour. When an air conditioner is listed by BTUs rather than by tonnage, it’s usually referring to BTUs per hour, so the two measures are directly comparable if you multiply or divide by 12.

How much CFM is a ton?

1 ton of cooling is equal to 400 cubic feet of air per minute. 2 ton of cooling is 800 cfm and so on. So a 4 ton unit will have 1600 cubic feet of air passing through the system every minute.

How many BTUs is a ton of heating?

Since BTUs are such as small amount, tons are used for greater convenience. One ton is equal to 12,000 BTUs.

How do you calculate BTUs?

For example, a 300 square foot room typically requires 7,000 BTUs to maintain a comfortable temperature, while a 1,000 square foot room requires 18,000 BTUs. A simple formula to determine your heating needs is: (desired temperature change) x (cubic feet of space) x . 133 = BTUs needed per hour.

How many ton is my AC?

Simply divide the BTUs by 12,000 to calculate the tonnage of your unit. For example, if your air conditioner is 36,000 BTUs, you have a 3-ton unit. Some manufacturers bury tonnage or BTU information in their model numbers. Look for an even, two-digit number between 18 and 60.

How many BTUs are in a half ton?

A two-and-a-half ton air conditioner has 30,000 BTU’s and can cool a home sized 1,201 to 1,500 square feet while a three ton unit has 36,000 BTU’s and is designed for homes 1,501 to 1,800 square feet.

What does 3.5 ton AC unit mean?

So, when we talk about an air conditioner unit rated at 1 ton or 2 or 3 ton, it just means the required amount of energy in BTU to provide that amount of cooling is 12,000 times the rated tonnage. For example, a 3 ton ac unit has 36,000 BTU/hr, a 5 ton ac unit has 60,000 BTU/hr.

What does tons mean in HVAC?

Tonnage is actually a measure of how powerful an AC is at cooling down a space. Tons are units of cooling power, so when we say that a system is a “two ton” or “five ton” unit, we’re indicating how powerful it is, not its weight. One ton = 12,000 BTUs of heat removed per hour from a space.

How many square feet will a 2.5 ton AC unit cool?

How do I know if my AC unit is big enough for my house?

Rule of Thumb — The maximum size unit you should buy would be 15% over the BTUs you need for cooling and 40% of the BTUs for heating. The max for heat pumps is 25%, since it handles both cooling and heating.

How many units does a 1 ton AC consume in an hour?

1.0 Ton Split AC – 0.98 kW per hour (Approx 1.0 unit per hour) 1.5 Ton Split AC – 1.49 kW per hour (Approx 1.5 unit per hour) 2.0 Ton Split AC – 1.73 kW per hour (Approx 1.7 unit per hour) 3 Star Split AC Electricity Consumption: 0.8 Ton Split AC – 0.8 kW per hour (Approx 0.8 unit per hour) Should I go for 3 star or 5 …

How much electricity does a 1 ton AC use?

As a general rule of thumb, for AC power consumption calculation you should take, 1 ton of cooling = 1,000 watts. 1.5 ton of cooling = 1,500 watts. 2 ton of cooling = 2,00 watts.
