Air conitioners - what does the BTU parsimonious?
Answers: First of adjectives, we need to know some jargon:
BTU: An energy component. 1Watt = 3.41 BTU/hour
SEER: Seasonal Energy Efficiency Ratio, SEER = BTU / Wattohour (see the A/C catalog)
Ton (s of cooling): standard ton of refrigeration = 12,000 BTU/hour (not used below)
kW: Kilo Watt = 1000 Watts
Calculating the annual cost of power for an air conditioner Source 1:
BTU/h × hours per year (h) × power cost ($/kWoh) ÷ SEER (BTU/Woh) ÷ 1000 W/kW
Let’s select a proper BTU from Source 2. Let’s speak the area to be cooled is 350 square foot. Then, from the chart, we need 8000 BTU/hour.
(Also From Source 2: If the room is heavily shaded, exhaust capacity by 10 percent. If the room is awfully sunny, increase capacity by 10 percent. If more than two culture regularly occupy the room, add 600 BTUs for respectively additional entity. If the unit is used surrounded by a kitchen, increase capacity by 4,000 BTUs. )
Let the catalog say the air conditioner have a SEER of 9 .The power cost is $0.2/kWoh and we will use it 1500 hours per year. Putting these to the formula
Annual cost = 8000 BTU/hour x 1500 hours per year x $0.2/kWoh ÷ 9 BTU/Woh ÷ 1000 W/kW
annual cost = 267 $
So, it will cost about 22$ a month. Note that this is solely an estimate, the real cost will modification with the warmth outside, the number of walls facing outside, the lightning system in the room, the sunlight coming to the room etc.
(BTU or Btu) is a element of energy used within the power, steam generation, and heat and air conditioning industries.
A BTU is defined as the amount of grill required to raise the warmth of one pound of liquid dampen by one degree Fahrenheit.
I'm not sure the heavens conditioner will kick on and rotten to keep the constant temp. you set.
Good luck, hope this help a little... check the encyclopaedia too
btu stands for british thermal units. its a breadth of what a unit will put out. i assume its the max capacity of the element.
