To calculate the cooling capacity (Tons):
\[ \text{Tons} = \frac{\text{CFM}}{400} \]
Where:
CFM stands for cubic feet per minute and is a measure of airflow. It is commonly used to specify the performance of air compressors, HVAC systems, and other equipment that moves or processes air. In the context of cooling systems, CFM is used to measure the volume of air that passes through an air conditioning unit, which is directly related to the unit’s cooling capacity.
In HVAC terms, a “ton” is a unit of measurement that describes the cooling capacity of an air conditioning system. One ton of cooling is defined as the amount of heat required to melt one ton (2000 pounds) of ice in a 24-hour period. This is equivalent to 12,000 BTU/hour or approximately 3.517 kilowatts. The term originated from the use of tons of ice to cool buildings in the past.
Let's assume the following values:
Using the formula:
\[ \text{Tons} = \frac{2000}{400} = 5 \]
The cooling capacity is 5 tons.
Let's assume the following values:
Using the formula:
\[ \text{Tons} = \frac{1200}{400} = 3 \]
The cooling capacity is 3 tons.
