5000 BTU is a tiny amount of cooling - are you sure you don't mean 50,000 BTU? A 5000 BTU might give you a drop of 5 degrees C in a 6' x 8' office with no south facing windows, as long as the ceiling isn't too high. For a normal 10' square room, 12,000 BTU is a more reasonable starting point, then add more for sources of heat gain in the room.
me thinks its 5000
5000 BTU's should work for a room that size.
A 5000 BTU air conditioner works on 1465 watts. If the BTU, 5000, is multiplied by .293071, the exact amounts are given. However, this does not display the amount of watts utilized by the air conditioner. The voltage and amperes would need to be known in order to figure the watts during usage.
It depends on room size, including ceiling height. In a 9x12 foot room with 9-foot ceilings, my 5000 BTU air conditioner cools to about 60-degrees.
500sq.ft
yes
The cooling capacity is the same. It all depends on the application as to which is better. If you have a large room then the 1 10000 Btu unit would be the better fit and probably cheaper. But if you need to cool two small rooms then the 2 5000 Btu units would probably be better.
A 5000 btu AC unit operating at 25% efficiency operating continuously for 1 hour, will use approximately 5858 watts or 5.858 KW/h.
It depends on the cost of electricity and the cost of natural gas in your area. Generally, using a 5000 BTU natural gas heater is cheaper than using a 1500 watt electric heater. Natural gas is typically more cost-effective for heating compared to electricity.
Barely. I think you'd be happier with two 8's and a 12. Of course, it depends on the configuration of the room, the location of the units and the climate, etc.
11800 BTU/hr is 3.46kW
