British Thermal Unit BTU
BTU stands for British thermal unit which measures the amount of energy produced by the unit and it is defined as the amount of heat required to raise the temperature of one pound (0.453592 Kg) of water by one degree Fahrenheit (-17.2222 Celcius) at sea level. The higher a BTU is, the more energy it will produce.
A smaller room requires lower BTU rating. On the other hand, a very large room requires high BTU rating.
How to choose perfect BTU for Air Conditioner
First, we need to find the area of room (size) and check what BTU’s needed from above standard BTU chart.
Area of rectangle room in square feet
= Width × Height square feet
Multiply the length by the width
Area of square room in square feet
= side × side
Multiply the length of one side by itself
Area of triangle room in square feet
= 0.5 × base × height square feet
One half of base times height
How to Figure most accurate BTUs for Air Conditioner
Standard ceiling height is 8-foot.
If height is higher than 8 feet,BTU should be increased
If room location is direct contact with sun’s light, BTU should be increased by
If room location is shaded during the day, BTU should be increased by
Above chart is for two person.
If it is permanently increased, 600 BTUs should be increased per person.
4000 BTU should be increased if you install it in a kitchen.
The energy efficiency rating (EER)
The EER rating is the ratio of British thermal units (BTU) per hour to Electricity consumed in wattage.
A 10,000-BTU portable air conditioner consumes 1,100 watts, so its (EER) is 9.09 (10,000 BTU/1,100 watts).
A 10,000-BTU portable air conditioner consumes 2,200 watts, so its (EER) is 4.54 (10,000 BTU/2,200 watts).
The higher the (EER) is, the more efficient and productive the air conditioning unit is. However, a higher (EER) is usually come up with meaning at a higher price.
Higher EER rating products can save consumers money in the long duration. Big companies and factories can save a huge amount in a short period if they use higher ERP rating products.
