difference between invertar and non inverter compressors for AC, refrigerators etc

difference between invertar and non inverter

Inverter compressor never stops, it changes speed so the refrigerant flow according to requirement, so power consumbiton varies differetn times and ultimately save

Non inverter ac compressor runs in fixed speed, so when temperatures reach desired state it stops. Again when tempretaruter goes up it turns on. As long it is on, it uses the same temperature. So it takes up much energy.On start up for motor there is a surge of electricity.

This is important because the compressor on your air conditioner consumes more power on start up than any other device in your home. Start up is the hardest time in the life of any type of electrical equipment. Ever notice that light bulbs almost always burn out when you first turn them on and not while they are on? This is due to the huge current that rushes in when a switch is thrown and power is first applied.

An ac compressor may consume 45,000 watts of power while the motor is trying to start - TEN times more power than it uses while running. By comparison, the large burner on an electric stove only consumes approximately 5,000 watts on high. The heat that accompanies the in-rush current can damage vital electrical components - the air conditioner compressor, the air conditioner run capacitor and contacts.

Your air conditioner uses anywhere from 5 to 10 times more power on start-up than it does while running. By reducing that time by up to 50%, there is far less electrical usage each and every time the air conditioner starts. For customers that are on a peak-demand payment program, these savings could be significant.

The second way that the 5-2-1 Compressor Saver® helps to lower air conditioning bills is through the protection it provides to the run capacitor. The run capacitor is the "heart" of the compressor and it determines how much electricity is consumed while the compressor or air conditioner is running. Without a 5-2-1 Compressor Saver® the run capacitor bears the brunt of the stress and electrical heat during start up.

As a result, over time the run capacitor wears down. When the run capacitor wears down, your air conditioner will still work, but it starts to use more electricity to run – just like the last step in a marathon is harder and requires more effort than the first. When weakened, your run capacitor and system can use 10% to 20% more electricity than before!

inverters are basically of DC inverters

The inverter ACs saves more energy and are more economical while still being environment friendly. A conventional AC starts multiple times and always runs at peak capacity. This means that every time it starts and it needs extra electricity to jump start its stationary motors and compressor like torque current. Without being too technical, one can think of it this way, it needs more power when it starts and it starts too many times. It also runs at full capacity each time requiring a lot of current.

In comparison, a DC inverter AC never turns off its compressor or motors. It reduces the electricity it needs and constantly keeps cooling or heating the room. When it does start the first time, a DC inverter AC starts off slowly so it doesn't require a massive torque current. The inverter ACs can start at low voltages as well thanks to the inversion mechanism. By running in a low power consumption state, the DC inverter ACs save electricity.

The inverter technology is not new and other countries have had these products for years. In most countries, the normal ACs are phased out completely. The DC inverter technology will soon start being used in other products as well.
