There are two conversion methods for the conversion between air conditioning units and room square. One is more precise calculation, the second is based on the use and habits of the room. The following small make-up for you to introduce 1.5 air conditioning a month about how much electricity charge? Suitable for what square meter room?
How much is the electricity charge for 1.5p air conditioner a month
One piece & asymp; 800W, which can't be said precisely. When using 'piece' as a unit, it will only appear in the advertisement words of the merchants. The accurate cooling power of the air conditioner can only be written on the name plate of the air conditioner.
1.5 is about 1200W - the air conditioner works for one hour and consumes 1.2kwh of electricity. However, no air conditioner will work continuously for 1 hour (unless the type of air conditioner is too small). Most air conditioners will shut down (fixed frequency air conditioning) or reduce power (frequency conversion air conditioning) when the indoor temperature reaches the set temperature.
We calculate the energy consumption after the compressor stops (constant frequency) or the energy consumption of low-power operation of the compressor (frequency conversion), the energy consumption of long-term operation of the air-conditioner for the first time and the starting energy consumption of the compressor into the electricity bill, assuming that the power consumption per hour is 0.5kwh (if the temperature of the air conditioner is higher, this value will be smaller; the power consumption of the frequency conversion air conditioner will also be smaller).
If it is used for 8 hours a day, that is 4kwh, and for 30 days it is 120kwh-0.5 yuan / kWh (average price of electricity in Beijing), it is 60 yuan / month.
What square meter does 1.5pp suit
This question is more difficult to answer because there are more variables. First of all, the power consumption of the air conditioner is out of proportion to the cooling capacity. For the same air conditioner with 1.5p, the cooling power may be 3900w (first-class energy efficiency) or 3400W (third-class energy efficiency). Let's take the average value of 3600W -- assuming that the cooling capacity of the air conditioner is 3600W.
Secondly, the cooling capacity required by rooms is also different. Some rooms have good thermal insulation effect, no sunshine, cold and humid all year round, and it's freezing enough without air conditioning. How much cooling capacity do you think it needs? Some rooms are open, and there are western windows, and there is air leakage everywhere. This kind of room needs chilling capacity.
We will not mention these special circumstances for the time being, but only the general commercial housing. The bedroom is relatively airtight, and the cooling capacity demand is about 130W / m2; the living room is generally open, and the cooling capacity demand is about 160W / m2.
Therefore, if the air conditioner with a cooling capacity of 3600W is placed in the bedroom, it can meet the requirements of a room of 3600 & divide; 130 = 27 m2; if it is placed in the living room, it can meet the requirements of a room of 3600 & divide; 160 = 22 m2.
