We have seen and used Air conditioners which directly run on
electricity and consume power according to capacity of air conditioner
irrespective of temperature settings of Air conditioners. Inverter technology
in air conditioners has changed whole scenario in world of air conditioners.

**There are following advantages of inverter air conditioners:-**

(i)
Quieter operation

(ii)
More economical operation and lower down
electricity bill

In Inverter technology , inverter equipped in air
conditioners has the ability to control the compressor’s speed and so as the
temperature which leads to draw lower current when temperature is set higher
and near auto stop, which ultimately leads to lower power consumption.

Inverter used in this technology is like inverter used in
houses for emergency power supply but added to this is microcontroller which
used to automatically adjust the temperature and current of compressor.

Since it provides smooth operation as compressor start and
stop are smooth as current is controlled to compressor through Voltage/
Frequency control method so jerk operations of compressors are avoided. Since
there are no jerk operations so operation of these air conditioners is smooth
and quieter. Smooth operation will leads to sharp fluctuations in load which
extends life of both equipment and power source supply. This will leads to
lower breakdowns.

**Difference between Fixed Speed Compressors and Variable Speed Compressors:-**

Fixed Speed compressors start and stop automatically at a
particular set temperature but in Variable speed compressors inverter regulates
the desired temperature by regulating the capacity of compressor.

Fixed Speed compressors always runs at 100% capacity but in
Variable speed compressors compressor runs at partial loads as per
requirements.

Also in our houses we can’t ascertain the exact size
required for a room which leads to oversized/ undersized air conditioners. So
by using inverter AC’s oversize factor can be reduced. If we install higher
capacity AC in our room then there will be higher power consumption irrespective of working hours of air
conditioner. But in inverter AC’s Power consumption will get controlled.

There are following advantages and disadvantages of using
inverter Air conditioners:-

**Advantages of Inverter Air conditioners:-**

(i)
Higher efficiency of air conditioners
as no. of start and Stop cycles get eliminated

(ii)
Effective temperature control can be
achieved

(iii)
Higher equipment life as these have
smoother operation

(iv)
Lower breakdowns

(v)
Quieter operation

**Disadvantages of Inverter Air conditioners:-**

There are following disadvantages of Inverter Air
conditioners:-

(i)
Energy loss during power conversion to DC and AC again leads to
losses of 4-6 %

(ii)
Higher initial cost as inverter leads to added cost

(iii)
Complexity of circuit made difficult to repair

**Price and Payback period:-**

A 1.5 Ton Air conditioner consumes 1.5 KWH as it is assumed
that 1TR consumes 1KW etc

Calculation for 8hrs/ day

Calculation for 8hrs/ day

**Operation of Fixed speed Air conditioners**

For 8 hrs of operation power consumption will be = 1.5 X 8 = 12 units

**For a Inverter AC**

An Inverter AC will operate for 30 minutes and for rest 30 minutes it will maintain the temperature. During maintaining the temperature for rest 30 minutes power consumption will be 300 W/Hr.

So power consumption /Hr= 0.750+0.300= 1.05 KWH

For 8 Hrs operation power consumption will be= 1.05 X 8= 8.4 Units

So Power saving will be = 12- 8.4 = 3.6 KW/ 8 Hrs

So do your calculations before buying any Air conditioner.

There will be price difference of 10,000-15,000 between
inverter Air conditioner and split Air conditioners.

So if we consider 12 Hrs operation for 180 days power saving
with Inverter AC will be= 12.6 X 180 = 2268 Units/annually

Rate per unit = 8 Rs

So Annual Savings will be= 18144/-

So payback for inverter AC’s is 3 months so do consider
these before buying the Air conditioners.
