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)
The Hourly Analysis Program (HAP) is a computer programme that aids engineers in the design of commercial HVAC systems. For load estimates, HAP use the ASHRAE transfer function approach, and for energy analysis, it employs thorough 8,760 hour-by-hour simulation methodologies.
Calculate the size of the room or house that has to be cooled. You can use a measuring tape to do this for a room.
To calculate the square footage of a room, multiply its length by its width.
Increase the square footage by a factor of 20. This is a measurement of the space's BTU cooling load.
The industry standard for sizing house HVAC return and supply ducts and registers is Manual D. Based on the findings of the Manual J load calculation, the Manual D duct design distributes the proper quantity of heating and cooling to each room.
The Manual J calculation is a formula that determines a building's HVAC capacity. Because it describes the size of equipment required to heat and cool a building, it's also known as an HVAC load calculation.
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.

Sir, ye baar baar " Thik hai, Thik hai " bolte ho na , ye bahot irritating lagta hai . 1 minute me ek baar " thik hai" bolenge to chalega.
Just amazing it is very very wonderful. Teacher thoughts in a very good way. App working properly. Certificate with this is great add. Going take more course
Yeh teacher. Saaf nhi Bolta aur concepts ko deep mein nhi batata. But Thik h nahi aane se achha h much to pta chlta h. Waise toh sahi padat h
