Heat load (BTU) = Length (m) x Width (m) x Height (m) x 141. So, for a room measuring 5m x 4m x 3m = 60 > x 141 = 8,460 BTU. (For measurements in feet, the formula becomes: Heat load (BTU) = Length (m) x Width (m) x Height (m) x 4)
Some HVAC designers may figure out how much air conditioning they'll need by measuring the area they wish to cool in square feet. They'll next divide the space (in square feet) by 500 and multiply the result by 12,000 to get the BTU.
Heat load calculation is a process of finding the amount of BTU (British Thermal Unit) required to meet the specific needs of a building. This process can be applied in a number of sectors such as architecture, engineering, construction, and manufacturing. It’s also important to note that there are many different levels of heat load calculation and each level has different requirements for data collection.
The purpose of heat load calculation is to make sure that you have enough energy when designing or building something. It also provides you with information on how much energy your design will use and where it will be used most often.
The factors that affect heat load calculation include temperature, insulation value, and thermal mass.
GOOD ONE FOR FRESHERS
Best learning app
Sir it would be a great help if you provide us the necessary resources like ISHRAE Handbook etc. Thank you.
Just want to say....Thank you soo much
HAP software,Uski official website se, INDIA region ka trial nahi mil pa raha hai........kya karen?
Thank you so much sir
Very helpful who are going to come in HVAC field.
