Do AC inverters consume less power?

In the heatwaves, we need to avoid the heat of the sun and hot weather, but turning on the AC is a huge burden on the budget. But innovation and technology have saved us from this problem. Today it is possible to enjoy the benefits of AC with inverter without being overburdened.

AC with inverter technology consumes less power, save money and provide more comfort in less time.

So what is this inverter air conditioning and how is it different from current technology? Let’s take a look at:

We usually adjust our room temperature according to our needs (for example, we keep the thermostat at 25 degrees Celsius). To get the temperature we want, the compressor has to run at a certain speed, which is the highest speed, which also consumes the most electricity.

When the temperature reaches the desired level, the thermostat compressor trips and its blower starts moving very slowly. But if there are air leaks in our room (from where the hot air comes in) then the room temperature rises suddenly. As a result, the thermostat issues instructions to the compressor to run again and restore our desired temperature.

Do AC inverters consume less power?

Ideally, tripping the compressor should be beneficial because we are using less electricity when the compressor is not running. But the irony is that the compressor consumes more power due to repeated tripping and restarting because it draws more power to start than when it is running in its normal mode.

Inverter technology has changed this: the running of the compressor is controlled by a different speed setting device that runs on a single DC of electricity.

Simply put, it keeps the speed of the motor running the compressor stable while feeling the room temperature. If the room temperature is high, the compressor will run at the same speed. If the temperature drops, so do the speed of the compressor.

This technology never lets the compressor trip, but keeps it running at the right speed to maintain the desired cooling. This reduces power consumption when starting a normal compressor.

Inverter ACs are expensive but they cover their cost through efficient cooling. They also consume less electricity due to fewer fluctuations.

Inverters reduce AC electricity bills by up to 30%, but depending on the ambient temperature, the type of coolant gas, the type of motor and other technical components, the rate can go up to 50%.

This makes the inverter AC more reliable and efficient than older AC units with less noise, fewer faults and less power consumption.

For example, a non-inverter AC with a 1.5 kW rating consumes 7.0 amperes and an AC inverter with a 2.6 kW rating draws 2.8 amperes (works between 0.9 and 3.0 kW). So a non-inverter AC spends 10 units on running for 8 hours, while an AC inverter spends only 4 units after running for the same length of time.

If we set the unit price at Rs. 6 per unit, then a non-inverter AC consumes Rs. 1,800 per month while an inverter AC consumes Rs. 720 per month for running the same amount. This saves you Rs. 1,080 per month.

If an inverter AC costs Rs. 1 lakh and a non-inverter AC costs Rs. 65,000 for the same rating and cooling, the cost of the inverter AC is reimbursed in just three years.

If you say that inverter ACs are more expensive than older models, you are right. But the fact is that if you can spend your money on inverter AC, it will save you a lot of money in the long run.
