To calculate the BTUs needed for a 5,000 square foot space with 12-foot ceilings, a rough estimate is to use 20 BTUs per square foot for standard conditions. However, because of the higher ceiling, you may need to adjust this to about 25 BTUs per square foot, resulting in approximately 125,000 BTUs (5,000 sf x 25 BTUs). Additional factors like insulation, windows, and climate should also be considered for a more accurate calculation.
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.
me thinks its 5000
5000 BTU's should work for a room that size.
A 5000 btu AC unit operating at 25% efficiency operating continuously for 1 hour, will use approximately 5858 watts or 5.858 KW/h.
Many things depend on this answer, so I'll offer you a guestimate. If your home is a single story, 2600 sq ft with 8 ft ceilings, and pretty loose leakage, you'll need approximately a minimum BTU/hr of 31200 BTU's, and a maximum of 62400 BTU's/hr. If it's a 2 story, with 8' ceilings, and average leakage, you'll want a minimum of 20280 BTU's and a maximum of 40560 BTU's/hr. Please check with your local professional to be exact.
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 takes about 50,000 btus to heat 1000 square feet
12,000 btu's per hour is one ton of cooling. Air conditioners for houses run between 2500 btu's and 400,000 btu's depending on the size of the house and number of units. 1 10ft x 12ft x 8ft room needs about 12,000 btu's of cooling to maintain a 20 degree difference in temperature.
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.
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.
