Is there a way to find out the requirement power (watts) for a room? (including lights, air condition etc)?

Question

I'm given a project that i need to find out the power required for power plant given that they will have a room, road lightings, etc I got all the numbers such as for a room it says that It will require 3.5kVA per unit. But they want more explanation how to get that numbers (basically i need to break it down or explain it further) Please I really need help. This project due like in a week. much appreciated for the answer :D:D:D:D

Answer 1

Power requirements for a room are determined by the total heat load. This heat load consists of solar load (if the room has an exterior window), people load (how many people use the room at a time, and how active are they), appliance loads (lights, equipment, etc.) and the ambient conditions surrounding the room and insulation (r-value for walls separating room from hot and cold areas).

If you need more specific help for a commercial project - e-mail me.

Answer 2

Yeah, each product has a watts consumption. Usually average but sometimes max. For a power plant max if preferable because when a motor starts it consumes more current and would in effect consume more power. Then once it gets over the inertia part it consumes the average current.

Answer 3

Not sure I understand the question very well.

Basically it looks like you need to research the power consumption of the items you need to account for, and add them up. I assume if you're doing a project like this, you know the basic power equations and stuff.
