Tips on Choosing AC (Air Conditioning) For Home

In determining the AC that we want to choose, we would be wise to weigh up before deciding to determine which brand air conditioner which we want to select. We should not be tempted by the cheapness of the purchase price. Because in the market we will find air conditioning ½ PK certain brands only 340 Watt power consumption, while other brands AC ½ PK 800Watt power consumption.
Of course the first AC ½ PK whose consumption is only 340 Watts purchase price is more expensive than the latter. But if we want to calculate the difference in price with the cost of electricity is needed, we will think again to select it.
Real examples on the market:
AC ½ PK brand A 355Watt power consumption at a purchase price Rp.2.450.000, -
AC ½ PK brand B 800Watt power consumption at a purchase price 2,000,000, -
Two of them have the same capacity that is 5000btu / h
If we only look at the price we would choose AC B is cheaper.
But if we want a little math, the difference in power consumption is 800W-355W Watt = 445 we have to pay more expensive each month. If we assume that the AC is turned on 10 hours a day and the price per kWh PLN = USD 500, - (rate goals. R1-2200), then we have to pay per day 0,445kWh x 10 hours x Rp 500, - = Rp.2.225, - more expensive.
Thus in a month we pay 30xRp.2.225, - = Rp. 66 750, - a sufficient amount of fantastic ... not. ??
That is, the difference in price Rp.450.000, - it will be back in less than 7 months.
