The three words, "5" and the electrician's page slipped in a second, and it didn't find out until the day the bill was paid — how could the air conditioner run 200 degrees more than the neighbor? Don't yell at the manufacturer, it's a "cool code" and it's really power-efficient。
The old calendar says one = 735 w, so it's 1. 5 ≈ 1100 w, and that sounds fine, but that's the algorithm for the last century's flat frequency compressor. Now, the frequency machine is velocityd by chips, able to jump between 75 w and 2 kw, more than 20 times the difference. The logic of conversion would have to focus on “refrigeration”: 1 = 2300 w cold and 1. 5 ≈ 3,500 w; the more energy efficient the greater the amount of electricity required to move 3,500 w cold into the house. The first-stage apf 5. 0 machine, 810 w, is sufficient; the third-stage energy efficiency is only 4. 0, with 960 w — the same brand and appearance, with a power deficit of 0. 15 degrees per hour, and an easy 60-degree price difference in the summer, enough to buy two barbecues。
The area matches the more potholes. Businesses open their mouths “15-20 m2” without asking whether it's sun, top floor, floor glass. The same 18 m2 has been measured, with an afternoon surface temperature of 45 °c in the west sun, an instant cold demand of + 30 %, a direct change of 1. 5 to a “cow-and-bow” car, a compressor unable to drop frequency and electricity taking off in situ. If you want to save your life, the sun, the top floor, and the glass house are pushed back on the “200 w cool per square metre” scale, you'd rather buy big or small, and don't worry about the 300-dollar difference, and save the electricity and irritating values。
Temperature settings also have a "six degree rule": lower 26 °c to 20 °c. Electricity consumption is not linear + 30 %, but a direct doubling - the frequency is most efficient at low frequency, and when temperature increases, high frequency runs, apf 5. 0 drops to 3. 0 at short notice. I'd like to get cold, get the fan back, and the wind temperature can be reduced by 1. 5 °c, and the air conditioner can save 20 % of electricity, and the old man's more than "cool" is。
It's not just a sign. It's a laboratory condition. It's not half a dime in the kitchen. The dumbest and most efficient way to do so is to use a power meter plugin to record the curve for one night, and then write the outdoor temperature, set the temperature, the room area on a small book, and three nights to calculate “real apf at home”. The same model was measured to be 15% energy efficiency off the outside of 33 °c, 30 % direct at 40 % c, and, once the data are down, it's no longer stupid to ask “why is the neighbor paying less for electricity than i do”。
The filter is not washed for a month, the wind is 10% off, the system miscalculates “the house is not cold enough”, the compressor continues to turn and the electricity costs slip away. If you have a poor ability to do it, you can book your cell phone calendar, take the filter out of the shower on the 1st of the month and change the power to 5%-10% in five minutes, more than any “energy-saving mode”. The sleep pattern, too, is “sweetly”, and the machine automatically rises by 2 °c at 4 a. M., saves 20 % a night. The key is not to freeze up, which is much more human than air conditioning at the clock。
The last sentence is telling the truth: air conditioning is a “three-point-seven” and the energy efficiency label is just a ticket, with tanning curtains, top-level warming, a monthly filter, 26 a/s+ fans, the ultimate operation to actually keep apf 5. 0 on the bill. Alternatively, level-i energy efficiency can run out of level-iii meters, not to blame air conditioning, but to blame itself for sending the money saved back to the grid。
