1 Answer. , swedish. Holland. Also, the country of Tulip mania and the first recorded speculative bubble. At the peak of tulip mania, in March 1637, some single tulip bulbs sold for more than 10 times the annual income of a skilled craftsman.
Step 4. Multiply the air conditioner power consumption per hour times the number of hours the unit runs per day to determine the daily power usage by the air conditioner. If the air conditioner is used 10 hours per day, the daily power usage is 10 kilowatt-hours per day.tep 5. Multiply the kilowatt-hours used per day times the electricity rate charged by the power company. If you use 10 kilowatt-hours daily and the highest-tier rate you pay is 20 cents, the air conditioner costs $2.00 per day, or about $60 per month.
The efficiency of air conditioners is expressed using a measure referred to as the SEER rating. SEER is an acronym that stands for Seasonal Energy Efficiency Ratio. The SEER rating of any air conditioning unit basically means how much cooling output the unit produces divided by the amount of electrical energy it uses.SEER rating allows anyone who is so inclined to calculate the kilowatts per hour that it would cost to operate an air conditioning unit.or example, if you were trying to decide between a 13 SEER air conditioner and a 16 SEER model, you would probably just want to know that the 16 SEER unit is approximately 20% more energy efficient than the 13 SEER unit. (about 23% more efficient to be more precise).
