THE FACTS. If you are sat at home, relaxing in your living room, watching telly, slobbing out, the most amount of heat that your body is going to produce is about 356 BTUs/hour.
What is the heat load of a person?
The average amount of heat given off by a person depends on the level of activity, and can range from about 100 W for a resting person to more than 500 W for a physically very active person.
How is human heat load calculated?
A more accurate heat load calculation for any type of room or building
- Calculate the area in square feet of the space to be cooled, and multiply by 31.25.
- Calculate the heat gain through the windows.
- Calculate the heat generated by occupants, allow 600 BTU per person.
How many BTUs is a ton?
12,000 Btu/
Air conditioners work something like blocks of ice in that they don’t produce cool air, but rather remove heat from the building. 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 many square feet will 24000 Btu cool?
A 24,000 BTU air conditioner would work best in a room between 1,400 and 1,500 square feet.

How many BTUs is 4 tons?
48,000 BTUs
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 the formula for BTU?
Many techs are familiar with the temperature rise formula for checking airflow. It is derived from the specific heat formula: BTU = weight x ΔT x Specific Heat.
How many BTU in 1 pound?
It is said that under ideal conditions one pound of wood @ 0% MC can produce 8600 Btu’s. Species that contain a high amount of resin can produce as much as 9000 + Btu’s/pound. Loss due to moisture from the combustion of hydrogen reduces the amount of potential Btu’s by about 6% .
How many BTU to heat a room?
Calculate the total number of BTUs required to heat the home. For each room, multiply the BTU per square footage times the square footage of the room. For example, a home located in Zone 5 with poor insulation would require 60 BTUs per square foot. Therefore, a room that is 300 square feet will need 18,000 BTUs (60 x 300).
What does a BTU measure?
Simply put, a Btu is a measurement of thermal energy—more specifically, the amount of thermal energy that it takes to boost a pound of liquid water by a single degree Fahrenheit . However, it is important to note that a Btu does not apply to liquid water at any temperature.
