Most people will tell you that ICT is a shortening for âinformation and communications technologyâ â option number one above. Letâs unpack that phrase. So it is âinformation technologyâ or âcommunications technologyâ. It is not âinformationâ or âcommunicationâ standing on its own. âInformationâ or âcommunicationâ has to go with technology â they cannot exist independently. You could shorten information and communications technology to just technology. Option 2
For example, a 24 ft. x 24 ft. garage with an eight-foot ceiling has a volume of 4608 ft.3 (24 * 24 * 8 = 4608) Final Formula. Once you have all the data assembled, multiply them together and divide by 1.6 to find the number of BTUs required to heat your garage. (Insulation * Volume * Temp. Rise)/1.6 = BTU. For example, if your garage was 4608 ft. 3 in volume, your temperature rise was 20Â°F, and your insulation rating was one, it would be: (1 * 4608 * 20)/1.6 = 57,600 BTU
600 spf A good general rule of thumb is 20 BTU per square foot. So, a 200 sf room would require a 4000 BTU ac unit. If you use 20btu per square foot to determine the required tonnage, you will be under sizing your system. For example 20btux1500sf=30000btu. There are 12000 btu per ton so you are using a 2.5 ton system to cool 1500 sf.
