Introduction to spreadsheet
The following calculation spreadsheet is used to determine the capacity of room air conditioner:
- Size of Air Conditioning for Your Room
- AC Size in BTU/Hr
- AC size in Tone
- Heating and Cooling BTU
Following Room Details are inputs:
- Length of room(foot)
- Width of room(foot)
- Windows in north side
- Window in south side
- Total room area in sq.foot
- Is there any blinds on the windows?
- Number of persons who may utilize the room
- Electrical Appliances in The Room:
- Electrical Equipment
- Electrical Lighting
|Software:||Calculate size of air conditioning for room|

one CFPP MV electrical panal room of a industrial building having the size of 10Mx18Mx4M. The panals heat load for electrical equipment is 54-KW.
How much will be the total cooling requirement ?.
Thank you so much, I am very grateful to you for sharing your hard work
Thank you, Jignesh.
was really helpful. thanks for the effort :-)
Great article about air conditioning! Thank you my friend for sharing this.
What should i enter into electrical equipment i.e. actual rating of equipment in watt or i have to enter Heat Dissipation in watt.
How to download excel spread sheet
I am interested in using the spread sheet but I have an issue. The spread sheet requires a password so as to edit, what’s the password.
air con calculation looks ok. What are the chances of modifying it to work for a substation, where
the amount of DOL drives, amount of free standing VSD drives of different KW ratings and soft starters are installed. Therefore taking into consideration the heat generated by each of these units.
sub station will have no windows and fire proof door [steel/flameproof coated wood]
one to consider all drives running 24hrs.
I hope, we must consider the volume of the room in calculations. Since heat transfer coefficient value for window is higher compared to bricks wall, we shall consider the windows in all directions.
what if the the window is in east and west? ,do we need to consider door?
thanks in advance
thanks for the spread sheet
if the window is facing east or west ,what will be the changes in calculation ,do i need to consider door measurement ,waiting for ur reply ,thanks
It is wonderful excel sheet, but how can I calculate the AC capacity without input the height of building, I have a room 20×10 m2 and 12 m height and the result of this sheet does not match the requirement.
How can we make a correction to external temperature?
I cannot download the file
