Electronics & Appliances Aircon split type

Dear @furriner, Please "Be careful on these forums because sometimes there are people who have been educated in the subject you extol so confidently about." and "... you are risking the wholesale lowering of the IQ in this thread ...".

Although he left off the H, it is obvious that the OP meant 27 kWH per day instead of kW of instantaneous load.

In the OP's original post he stated: "Just had it completely cleaned. last reading 27 kw 24 hours, ..." The "24 hours" should have given you a hint that he meant the electricity consumed over the entire 24 hour day.

In a later post, the OP attempted to clarify this by including the calculation of cost per day: "the one in question is using 27 KW a day * 10 = 270 pesos." The fact that the OP is multiplying the "27 KW a day" by the utility rate of 10 pesos per kilowatt hour (kWH) should make it obvious to you that he actually meant 27 kilowatt hours (kWH) per day instead of 27 kW of instantaneous load.

As an electrical engineer you should realize that this is the power consumed over a 24 hour period. Assuming that the air conditioner is running all day, we would take the 27 kWH divided by 24 hours per day to get 1.125 kW per hour or 1,125 watts per hour consumed. It has been hot lately so assuming the air conditioner is running at full load and not cycling down, 1,125 watts at 750 watts per HP would equate to a 1-1/2 HP unit. Which is much less than the 27,000 watts you assumed as the instantaneous load.

Furthermore, they may be looking at the meter and not considering the other appliances in the apt.

@jimeve, Does the 27 kWH include other appliances like a refrigerator? Is the tenant running it all day? Please also give us the rated power of the air conditioner unit.

It has been more humid lately. I noticed that the freezer in my refrigerator frosted up which reduced its efficiency. It was running all day and not cycling off. After defrosting it the electrical consumption dropped way off.

Thanks

 

According to the above mathematic does it implicate that a 0,75 HP window unit will consume around 0,56 Kwh an hour??

 

Figures quoted were for a split type Inverter

 

Hello SkipJack, that includes all the appliances. 1 hp split inverter aircon and yes I meant to say 27 KWH.

 

That was an example if you care to read what I posted about the drill. Please refrain from condescending remarks, It's not the first time. I have been a member on this form since it was formed 2006, I joined two months later in February 2007. You being a new member have to learn some manners. Keep out of my way.
