The BTU (British Thermal Unit) is a standard measure used for rating the energy output of appliances (such as heating and cooling systems) and for measuring energy consumption. One BTU is equal to the energy needed to increase the temperature of one pound of water by one degree Fahrenheit. ...
2. Calculations for a small server room or data closet In this example, there's a small server room, data closet or miniedge data centerthat might be found in a generic office tower in a large city. These calculations can help determine your cooling requirements in watts, and any power s...
Specific Heat Capacity (c here) of a substance is the heat required (q) to raise the temperature of 1 unit mass of that substance by 1 unit c=qmΔT Where ΔT is the change in temperature The more heat you require to change the temperature of one unit mass of a substance by one ...
CFM Calculation:Airflow has to be strong enough to change the complete volume of 300 sq ft room (with 8 sq ft ceiling height) 2 times per hour. Volume of a room = 300 sq ft x 8 ft = 2,400 ft3. To change it 2 times per hour (ACH = 2), we need to deliver 4,800 ft3per ...
A room air conditioner's efficiency is measured by the energy efficiency ratio (EER). The EER isthe ratio of the cooling capacity (in British thermal units [Btu] per hour) to the power input (in watts). The higher the EER rating, the more efficient the air conditioner. ...
