Q_s = 1.1*CFM*TC
This formula uses 3 Variables

Variables Used

Sensible cooling loads from ventilation air - (Measured in Watt) - Sensible cooling loads from ventilation air is the heat the results from an increase or decrease in the amount of moisture held by the air due to ventilation air.
Air ventilation rate in Cubic foot per minute - Air ventilation rate in Cubic foot per minute is the amount of air inhaled in a specified time period (eg. per minute) and it is also called breathing rate and inhalation rate.
Temperature change between Outdoor and Inside air - (Measured in Kelvin) - Temperature change between outdoor and inside air is the temperature difference between air outdoor and inside of the specified space.

STEP 1: Convert Input(s) to Base Unit

Air ventilation rate in Cubic foot per minute: 25 --> No Conversion Required
Temperature change between Outdoor and Inside air: 12 Fahrenheit --> 262.038882255554 Kelvin (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_s = 1.1*CFM*TC --> 1.1*25*262.038882255554

Evaluating ... ...

Q_s = 7206.06926202774

STEP 3: Convert Result to Output's Unit

7206.06926202774 Watt -->24604.5898837471 Btu (th) per Hour (Check conversion here)

Sensible Cooling load from ventilation air Formula

Sensible cooling loads from ventilation air = 1.1*Air ventilation rate in Cubic foot per minute*Temperature change between Outdoor and Inside air
Q_s = 1.1*CFM*TC

What is the difference between total cooling and sensible cooling?

Valuable cooling capacity is lost and the air conditioning unit works less efficiently. The entire sum of cooling capacity generated is known as the total cooling capacity. The proportion that is used for purposely cooling the air is called sensible cooling capacity.
