Moreover, How many kW is in a ton?
cooling capacity of 1 ton is equal to 3.517 kW of power.
How do I calculate BTU needed?
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.
Also Is 8000 BTU enough for a bedroom? Recommended BTU By Room Size
If you are looking for an air conditioner for a room measuring say 10′ x 15′ (150 square feet), the recommended BTU range is up to 5400. … Once you get into 340 and 400 square feet per room, you’d need an 8,000 or 9,000 BTU air conditioner, respectively.
How do I calculate BTU for air conditioner?
To calculate the size, simply multiply the length times the width of the room or area to be cooled. Then, as a practical number, multiply that total times 25 BTU. This allows ample cooling, whether it is a rainy, moist day or a hot, sunny, humid day.
