Myth 1 – They consume more power because the compressor runs continuously
The inverter AC was invented to solve the issue of reducing consumption of electrical energy. That the compressor is continuously in operation is a statement of fact, but the power consumption is substantially lower than that of a conventional fixed speed AC because the variable speed drive regulates the frequency of current supplied to the compressor thereby bringing down power consumption.
Myth 2 – They are less efficient than conventional fixed rate AC
After initial cooling, the conventional AC idles until the room temperature rises and then the compressor restarts the cooling process, and this cycle continues. The result is that there will be in-between periods when cooling comfort is lost. An inverter AC runs throughout and the compressor is supplied with adequate power to maintain the room temperature at the desired level. Coolness is thus maintained consistently.
Myth 3 – Inverter AC compressor may more easily suffer a breakdown
This belief has gained ground because the compressor is continuously in operation. But, the continuous operation of the motor of the compressor is at speeds regulated by the variable speed drive which controls the frequency of the current supplied. The fixed speed AC are in greater danger of breakdown because of the enormous torque of the motor to go from a state of inertia to full speed every time the compressor run begins.
Myth 4 – Inverter AC are expensive
In terms of capital cost, inverter AC are more expensive, but they give life-time value for money through the significant savings in monthly power bills. These savings may result in more than compensating for the higher outlay for acquisition of the AC.
